Summary Comparison of Impacts, Proposed OPSP and Alternatives...............................19-19 DRAFT ENVIRONMENTAL IMPACT REPORT PAGE viii OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT This page intentionally left blank. OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 1-1 1 INTRODUCTION PURPOSE OF THE ENVIRONMENTAL IMPACT REPORT The California Environmental Quality Act and the Guidelines promulgated thereunder (together “CEQA”) require an Environmental Impact Report (EIR) to be prepared for any project which may have a significant impact on the environment. An EIR is an informational document, the purposes of which, according to CEQA are “to provide public agencies and the public in general with detailed information about the effect which a proposed project is likely to have on the environment; to list ways in which the significant effects of such a project might be minimized; and to indicate alternatives to such a project.” The information contained in this EIR is intended to be objective and impartial, and to enable the reader to arrive at an independent judgment regarding the significance of the impacts resulting from the proposed project. This EIR evaluates the potential environmental impacts that may be associated with the Oyster Point Specific Plan (OPSP), including the first phase of development (Phase I Project) in the City of South San Francisco, California and the related Redevelopment Plan amendment. The applicant is Oyster Point Ventures, LLC and the City of South San Francisco Redevelopment Agency. The Lead Agency is the City of South San Francisco. The applicant is seeking amendments of the City’s General Plan, Redevelopment Plan and Oyster Point Marina Specific Plan, as well as several entitlements to enable development of the OPSP, including but not limited to approval of a subdivision or parcel map, design review, a Transportation Demand Management (TDM) Plan, a Development Agreement, and a Disposition and Development Agreement to enable redevelopment of the OPSP and Phase I Project site. The OPSP would include replacing the existing light industrial/office park with an office/research and development (R&D) development, improvements to the site circulation, utilities, and landfill cap, provision of a flexible use recreation area and bay-front open space, and replacement of uses in the Oyster Point Marina area, potentially including one or two hotels with an aggregate of up to 350 rooms. Approval must be given by the City of South San Francisco and trustee agencies, including the Regional Water Quality Control Board and Bay Conservation and Development Commission before construction may begin. EIR REVIEW PROCESS This EIR is intended to enable City decision makers, public agencies and interested citizens to evaluate the broad environmental issues associated with the overall character and concept of the proposed OPSP. An EIR does not control the agency’s ultimate discretion on the OPSP. As required under CEQA, the agency must respond to each significant effect identified in the EIR by making findings and if necessary and warranted, by adopting a statement of overriding considerations. In accordance with California law, the EIR must be certified before any action on the project can be taken. However, EIR certification does not constitute project approval. Together, this Draft EIR (Draft EIR) and the Final EIR (Final EIR) will constitute the EIR for the project. During the review period for this Draft EIR, interested individuals, organizations and agencies DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 1-2 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT may offer their comments on its evaluation of project impacts and alternatives. The comments received during this public review period will be compiled and presented together with responses to these comments in the Final EIR. The South San Francisco City Council will review the EIR documents and will determine whether or not the EIR provides a full and adequate appraisal of the project and its alternatives. In reviewing the Draft EIR, readers should focus on the sufficiency of the document in identifying and analyzing the possible environmental impacts associated with the Project. Readers are also encouraged to review and comment on ways in which significant impacts associated with this Project might be avoided or mitigated. Comments are most helpful when they suggest additional specific alternatives or mitigation measures that would provide better ways to avoid or mitigate significant environmental impacts. Reviewers should explain the basis for their comments and, whenever possible, should submit data or references in support of their comments. The 45 day review period for the Draft EIR is from January 25, 2011 to March 10, 2011. Comments should be submitted in writing during this review period to: Gerry Beaudin, Senior Planner Department of Economic and Community Development City of South San Francisco 315 Maple Avenue South San Francisco, CA 94083 Please contact Gerry Beaudin at 650-877-8535 or gerry.beaudin@ssf.net if you have any questions. After reviewing the Draft EIR and the Final EIR and certifying the EIR as adequate and complete, the South San Francisco City Council will be in a position to consider approval, denial, or modification of the OPSP and Phase I Project and related actions. CONTENT AND ORGANIZATION OF THE EIR A Notice of Preparation (NOP) was issued in February 2010 to solicit comments from public agencies and the public regarding the scope of the environmental evaluation for the project (see Appendix A). The NOP and all written responses are presented in Appendix A. The responses were taken into consideration during Draft EIR preparation. An Executive Summary follows this introduction as Chapter 2. This summary presents an overview of the project and the potentially significant environmental impacts which may be associated with the project, including a listing of recommended mitigation measures and a discussion of those impacts which would remain significant and unavoidable even following mitigation. The Draft EIR presents a description of the project in Chapter 3. Chapters 4 through 18 present environmental analysis of the OPSP and Phase I Project, focusing on the following issues: 4.Aesthetics 5.Agricultural, Forest and Mineral Resources 6.Air Quality 7.Biological Resources 8.Cultural Resources 9.Geology and Soils CHAPTER 1: INTRODUCTION OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 1-3 10.Greenhouse Gas Emissions 11.Hazards and Hazardous Materials 12.Hydrology and Water Quality 13.Land Use and Planning 14.Noise 15.Population, Public Services and Recreation 16.Traffic/Transportation 17.Utilities/Service Systems Chapter 18 presents Other CEQA Considerations, including a discussion of a discussion of significant and irreversible modifications in the environment, growth inducing impacts, and cumulative impacts. Chapter 19 presents an evaluation of the environmental effects which may be associated with the proposed project and three alternatives evaluated: the "No Project" alternative and two reduced development intensity alternatives. Chapter 20 lists the persons who prepared the Draft EIR, identifies those persons and organizations contacted during the preparation of the document, and lists the reference materials used.

OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 2-1 2 EXECUTIVE SUMMARY AND IMPACT OVERVIEW SUMMARY DESCRIPTION This EIR analyze the potential for environmental impacts resulting from implementation of the proposed Oyster Point Specific Plan (OPSP), including the first phase of development (Phase I Project) in the City of South San Francisco, California. The applicant is Oyster Point Ventures, LLC and the City of South San Francisco Redevelopment Agency. The Lead Agency is the City of South San Francisco. The applicant is seeking amendments of the City’s General Plan, Redevelopment Plan and Oyster Point Marina Specific Plan, as well as several entitlements to enable development of the OPSP, including but not limited to approval of a subdivision or parcel map, design review, a Transportation Demand Management (TDM) Plan, a Development Agreement, and a Disposition and Development Agreement to enable redevelopment of the OPSP and Phase I Project site. The OPSP site includes areas commonly known as the Oyster Point Business Park and the Oyster Point Marina. The Oyster Point Business Park encompasses 25 acres of the OPSP area. It is a privately owned series of five single-story light-industrial buildings at 375/377, 379, 384, 385 and 389 Oyster Point Boulevard that were developed in the early 1980s totaling 403,212 square feet of space with surrounding parking (see Figure 3.2). Currently, these buildings are occupied by a variety of light industrial, office, and Research and Development (R&D) tenants. The 48-acre area known as the Oyster Point Marina area fills the remainder of the OPSP area other than roadway elements, which complete the 80-acre area. This land served as a municipal landfill for the City of South San Francisco from 1956 until it stopped accepting waste in 1970. The Marina area is owned by the City of South San Francisco and managed through a Joint Powers Agreement with the San Mateo County Harbor District. Currently, this area hosts a variety of uses including a dry boat storage area, a marine support services building, two small office buildings, a 30-room inn and banquet hall, a bait and tackle shop, a boat and motor mart and a yacht club, all totaling 74,360 square feet. The remaining area is vacant or serves as parking for the docks, boat ramp, and the Bay Trail (see Figure 3.2). The Oyster Cove Marina is privately owned and located to the west of the Oyster Point Business Park; it contains 235 berths. The Oyster Point Marina is located on the north side of the Oyster Point Marina area and contains 600 berths, a boat ramp, fuel dock and fishing pier. The South San Francisco Ferry Terminal with service to/from San Francisco and the East Bay is currently under construction and scheduled to be completed at the Oyster Point Marina in early 2011. (The Ferry Terminal is shown on Figure 3.3). This Ferry Terminal is a separate project with its own certified environmental review. As the Ferry Terminal project is currently underway, it has been assumed for this analysis that the Ferry Terminal will be operational. The OPSP would include replacing the existing light industrial/office park with an up to 2,300,000 square foot office/research and development (R&D) development, improvements to the site circulation, utilities, and the landfill cap, provision of a flexible use recreation area and bay-front open space, and replacement of uses in the Oyster Point Marina area, potentially including one or two hotels with an DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 2-2 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT aggregate of up to 350 rooms. Approval must be given by the City of South San Francisco and trustee agencies, including the Regional Water Quality Control Board and Bay Conservation and Development Commission before construction may begin. The OPSP is analyzed on a programmatic level in this EIR. The Phase I Project is the first phase of the OPSP and included in the description of the OPSP in the above paragraph. The Phase I Project involves improvements to the site circulation, utilities, and the landfill cap, provision of a flexible use recreation area and bay-front open space, and development of up to 600,000 square feet of Office/R&D uses on a currently vacant parcel at the southeast corner of Oyster Point Boulevard and Gull Drive. The Phase I Project is analyzed on a project level in this EIR. OYSTER POINT SPECIFIC PLAN IMPACTS AND MITIGATION MEASURES The analyses in Chapters 4 through 18 of this document provide a description of the existing setting, identify potential environmental impacts associated with implementation of the OPSP and Phase I Project, and recommend mitigation measures to reduce or avoid potentially significant impacts that could occur as a result of OPSP implementation. Table 2.1 at the end of this chapter lists a summary statement of each potentially significant impact and corresponding mitigation measure(s), as well as the resulting level of significance. SIGNIFICANT AND UNAVOIDABLE IMPACTS THAT CANNOT BE MITIGATED TO A LEVEL OF LESS THAN SIGNIFICANT Significant environmental impacts require the implementation of mitigation measures or alternatives (where feasible) to reduce those impacts, or a finding by the Lead Agency that possible mitigation measures are infeasible for specific reasons. For some of the significant impacts, feasible mitigation measures either have not been identified, have uncertain feasibility, or may not be effective in reducing the impacts to a less than significant level. These impacts are designated as significant and unavoidable, as follows: x Air Quality: Development anticipated as a result of the OPSP would increase employment in an area designed for employment centers served by local and regional transit. However, city-wide, vehicle miles traveled (VMT) was projected to increase at a faster rate than the city’s population, which conflicts with assumptions in the local Clean Air Plan. Mitigation Measure Traf-1 would reduce this impact by requiring implementation of a TDM Plan to reduce trips and VMT. However, the TDM Plan would not likely reduce the number of trips and VMT to an amount that would be assumed under the existing General Plan designation for the site. Thus, this impact would be considered significant and unavoidable. x Greenhouse Gas Emissions: The Phase I Project and development anticipated as a result of the OPSP would increase operational emissions of greenhouse gasses. These emissions would be above the Air District’s 2010 thresholds. Although this analysis was begun before those thresholds were in place, this has conservatively been determined to be a significant and unavoidable impact. The developer plans many measures that would reduce greenhouse gas emissions including implementation of City-required waste reduction and implementation of an aggressive Transportation Demand Management Plan and design intended to achieve LEED certification. x Noise: Noise generated by construction on the site would substantially increase noise levels at live- aboard boats in the vicinity of the site temporarily. This impact would be partially reduced through implementation of construction noise control measures (Mitigation Measure Noise-5), but the impact would remain significant and unavoidable as a result of the extended period of time that adjacent receivers could be exposed to construction noise though the noise increases would be both episodic and temporary. CHAPTER 2: EXECUTIVE SUMMARY AND IMPACT OVERVIEW OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 2-3 x Traffic: The Phase I Project and proposed OPSP would increase traffic to and from the site, resulting in declines in operation of and queuing greater than the established standards at U.S. 101 ramps and/or intersections serving them as well as the mainline U.S. 101. IMPACTS REDUCED TO A LEVEL OF LESS THAN SIGNIFICANT THROUGH MITIGATION The following potentially significant impacts could be reduced to less than significant levels with implementation of mitigation measures: x Aesthetics: The many windows and outdoor lights associated with increased development intensity within the OPSP area could potentially be substantial sources of nighttime light and daytime glare. A lighting plan to minimize light pollution (Mitigation Measure Vis-2a) and choice of building materials to reduce glare (Mitigation Measure Vis-2b) would reduce the impact to less-than- significant. x Air Quality: Development anticipated under the OPSP may expose sensitive receptors to health risks through development of new non-residential development that may be sources of TACs and PM2.5 and the potential for development of ancillary uses, such as daycare facilities, that would bring sensitive users to the site. Such exposure would represent a potentially significant impact. Assessment of health risk for specific projects that come through which will bring sensitive users to the site for long periods each day, such as child daycare facilities, and implementation of appropriate mitigating features as outlined in mitigation measure Air-2 would ensure that resulting TAC and PM2.5 exposures would be below the BAAQMD thresholds and therefore less-than- significant. Construction of development projects under the OPSP would result in temporary emissions of dust, diesel exhaust and odors that may result in both nuisance and health impacts. With implementation of fugitive dust, emissions and odor reduction measures (Mitigation Measures Air-4a and Air-4b), impacts would be reduced to a level of less than significant. x Biological Resources: Development of the OPSP could result in disturbance or loss of wetland or aquatic habitats. Implementation of Mitigation Measures Bio-2a through Bio-2d would reduce impacts to a less-than-significant level through delineations of jurisdictional areas along the shoreline, avoidance or minimization of impacts through specifics of design as possible, restoration of temporarily impacted areas where feasible, and compensation for/replacement of impacted habitat when loss cannot be avoided. Increases in turbidity resulting from construction constitutes a potentially significant impact to aquatic wildlife species, including special-status fish species such as steelhead and sensitive native species such as the Olympia oyster. Water quality degradation could also negatively impact eelgrass beds if they occur in the OPSP area. Implementation of Mitigation Measures Bio-3a and Bio-3b would reduce indirect impacts to water quality and sensitive habitats from construction- period increases in turbidity to a less-than-significant level through minimization of soil disturbance adjacent to these habitats and implementation of best management practices for water quality during construction. Stormwater outfalls from the buildings to be constructed in the southwestern part of the site outfall into vegetated swales that are to be constructed just upslope from the wetlands and tidal channel that form the southwestern boundary of the site. If these swales are not adequately constructed, there is some potential for excessive erosion or the release of untreated runoff into these wetlands and tidal waters. Implementation of Mitigation Measure Bio-4 will ensure adequate capacity and maintenance of the stormwater system to reduce these impacts to a less-than-significant level. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 2-4 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Construction-related noise and activity could disturb or displace special-status breeding birds and/or burrowing owls. These potential impacts are reduced through implementation of pre- construction nesting bird and burrowing owl surveys (and resulting recommendations) as called for in Mitigation Measure Bio-6 and Bio-7a through 7c. OPSP’s proposed buildings will project higher than existing structures, creating new, somewhat greater strike hazard for migrating and foraging birds. Implementation of building design and lighting measures presented in Mitigation Measures Bio-10a and Bio-10b will avoid and minimize such impacts. If in-water construction is undertaken as contemplated for a couple of the piers as a part of the OPSP, such construction activities could result in impacts to Essential Fish Habitat, special-status fish or marine mammals, Olympia oysters and/or eelgrass beds. These impacts could be reduced through implementation of Best Management Practices for water quality (Mitigation Measure Bio- 3a) as well as Best Management Practices specific to species and appropriate construction techniques and worker training, surveys when necessary, avoidance if possible, and replacement when populations are impacted and avoidance is not feasible (Mitigation Measures Bio-12, 13-a -b, 14-a -b -c, and 15-a, -b -c.) Avoidance of salmonid migration periods and wetland and aquatic vegetation and appropriate worker training (Mitigation Measure Bio-12) as well as implementation of best management practices for water quality during construction (Mitigation Measure Bio-3a) would reduce this impact. Implementation of mitigation measures Bio-13a and Bio-13b would reduce impacts to special- status fish and marine mammal species due to percussive in-water construction activities to less- than-significant levels by minimizing percussive noise through utilization of appropriate design and construction techniques. x Cultural Resources: Construction in the OPSP area could disturb unidentified archeological or paleontological resources and/or human remains. Halting of work in the event such resources are discovered during construction and implementation of appropriate measures (Mitigation Measures Cultural-1a and 1b) would reduce these impacts to less than significant levels. x Geology and Soils: The Bay Area is a seismically active region, so there is a high probability that the proposed development will be subjected to strong to violent ground shaking from an earthquake during its design life including the possibility of seismic-related ground failure such as liquefaction, densification, ground surface settlement and/or failure of the perimeter dikes. Compliance with applicable regulations (Mitigation Measures Geo-2a, -2c and -3b) and a design- level geotechnical investigation (Mitigation Measures Geo-2b, -3a and -4) will reduce these impact. Variable subsurface conditions at the OPSP site include varying thicknesses of Bay Mud, landfill waste and other fill as well as sloping bedrock surface and possible paleochannels in the north/northwest of the site. These will influence the design, performance and constructability of foundation systems for the proposed buildings, which could include deep foundations (Mitigation Measure Geo-5a), pre-drilling and pointed-tip pile configurations (Geo-5b), an indicator pile program (Geo-5c), and accounting for drag load on deep foundations due to consolidation and on- going decomposition-induced settlement of the wastes (Geo-6). Placement of buildings over the landfill cap could allow landfill gas to accumulate beneath building floors and permeate into the building interiors, which could adversely affect the health and safety of building occupants. This impact would be reduced through implementation of measures CHAPTER 2: EXECUTIVE SUMMARY AND IMPACT OVERVIEW OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 2-5 for the control of landfill gas such as a collection system, floor slab shielding and interior alarms (Mitigation Measure Geo-7). Placement of additional fill or other new loads at the site will result in additional site settlement due to consolidation settlement of the Bay Mud soils and the compaction and decomposition induced settlement of submerged waste and waste above groundwater. This impact will be reduced through compliance with design-level Geotechnical Investigation recommendations to minimize new fill and structure loads (Mitigation Measure Geo-8a) and building-soil interfaces designed to allow free movement to accommodate ongoing settlement (Geo-8b). Placement of underground utilities in the OPSP area could result in impacts related to contact with hazards and damage to the landfill cap during excavation or maintenance, and differential settlement causing stresses at building connections and in utility line materials, and disruption of the flow gradient. These impacts would be reduced through monitoring and testing during excavation (Mitigation Measure Geo-9a), locating utilities in common trenches (Geo-11) and in the soil cap when practicable (Geo-9b), sealing trenches and underground structures to preclude gas intrusion (Geo-9c), requiring utility trenches and other underground structures to be configured to maintain continuity of the landfill cap (Geo-10), using flexible pipe materials and joints to accommodate settlement (Geo-12), and consideration of increasing the flow gradient in sewers and storm drains of utilizing a pumping system rather than gravity flow (Geo-13). Soils exposed during site grading would be subject to erosion during storm events and could impact the Bay. Implementation of a required Storm Water Pollution Prevention Plan (Mitigation Measure Geo-14) would reduce this impact. x Hazardous Materials: While specific tenants have not yet been identified, research laboratories are likely to handle materials considered to be biological hazards, chemical hazards and/or carry a risk of fire or explosion, which pose a risk of accidental upset and environmental contamination from routine transport, storage, use and disposal. This impact is reduced through compliance with existing regulations, plans and programs (Mitigation Measures Haz-1a through Haz-1e and Haz-5). Hazardous materials could be accidentally released during site preparation and construction activities in the vicinity of the landfill or during demolition of buildings. These impacts are reduced through implementation of measures to avoid releases of wastes or waste water into the environment and to protect workers and the public during excavation and re-disposition of landfill materials (Mitigation Measure Haz-2) and implementation of a demolition plan (Haz-3). Landfill materials, which include hazardous materials in solid waste, groundwater and soil vapor, will remain on-site following construction. Installation of new structures presents the potential for build up of soil gasses within the structures, posing a risk to building occupants and additional loading of the site surface could increase the rate of on-site waste settlement, leading to off-site migration of leachate. Exposure during maintenance work on underground utilities in the vicinity of the landfill can also not de discounted. Mitigation Measures Haz-4a through Haz-4e and Haz-6a through -6d reduce the risk of future releases related to future exposure to existing landfill materials. x Hydrology and Water Quality: Proposed development in the vicinity of the landfill poses a risk of off-site migration of lechate as a result of modification of the landfill cap and underlying Bay Mud. This impact will be reduced through use of BMPs during installation of foundation piers (Mitigation Measure Hydro-1), landfill cap upgrades (Haz-4a), and continued monitoring for leachate migration during operation and maintenance (Haz-4d and -4e). Construction activities at the site will create temporary and long term alterations of the site terrain, creating potential erosion concerns. Additionally, the migration of laboratory and DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 2-6 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT parking lot pollutants into the bay could potentially impair water quality. This impact would be reduced through implementation of Phase I NPDES General Construction Activities permit requirements and a SWPPP (Mitigation Measures Hydro-3 and Hydro-2). x Traffic: Development of the Phase I Project and OPSP would result in increases in traffic that would impact local intersections. Mitigation measures have been identified to reduce these impacts to less than significant levels including improvements included in the Transportation Improvement Plan (TIP) and those to which development would be required to contribute a fair share. Additionally, because of the size of the OPSP, implementation of a Transportation Demand Management Plan would be required to reduce peak-hour trips. x Utilities: Development under the OPSP would exceed capacity of some elements of the wastewater system, including Pump Station Number 2 and the Oyster Point Subtrunk. While adequate capacity exists to accommodate the Phase I Project, fair share contribution to improvements to Pump Station Number 2 (MM Util-2a) and the Oyster Point Subtrunk (MM Util-2b) will be required for all projects under the OPSP. IMPACTS DETERMINED NOT TO BE SIGNIFICANT The following impacts related to the OPSP and Phase I Project would be considered to have no impact or a less than significant impact, with no mitigation required: x Aesthetics: The San Bruno Mountains and the San Francisco Bay are scenic resources that can be viewed from the OPSP area and surrounding areas, including from the recreational Bay Trail. Development in the OPSP area will block partial views of these scenic resources from private development and from portions of the U.S. 101 and Bay Trail. However, due to the nature of the views and site and fact that views along U.S. 101 and the Bay Trail change as users move along them, the impact related to scenic vistas and views is less than significant. The OPSP area is not located near a Scenic Highway and the change in the visual character of the site would not be considered adverse. x Air Quality: The OPSP would intensify the land use, and would result in new air pollutant emissions, primarily from automobile use. However, these emission levels are anticipated to be below thresholds of significance. Due to the nature of uses proposed in the OPSP area and the surrounding area, operation would not be anticipated to create objectionable odors affecting a substantial number of people. x Biological Resources: The OPSP area is not within an area covered by a Habitat Conservation Plan (HCP) or Natural Community Conservation Plan (NCCP), or proposed for salt marsh restoration. Development of the OPSP would result in the modification or loss of common terrestrial habitats, including potentially habitat for non-breeding special-status wildlife species. However, none of these habitats represent particularly sensitive, valuable (from the perspective of providing important wildlife habitat), or exemplary occurrences of these habitat types and would be no substantial loss of foraging or non-breeding habitat for any special-status species. Development would also likely result in removal of one or more mature blue gum trees that may satisfy size requirements for a “protected tree” under the City of South San Francisco’s Tree Protection Ordinance. A permit would be required for removal of any “protected trees” though this species in particular provides low habitat functions and would not otherwise be expected to have an impact on biological resources. Development under the OPSP would also cause increased lighting impacts and recreational disturbance on wildlife, however the area is already largely habituated to high levels of human CHAPTER 2: EXECUTIVE SUMMARY AND IMPACT OVERVIEW OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 2-7 activity and artificial lighting from existing development and the impacts from increased development would be less than significant. x Geology and Soils: The OPSP site is not contained within an Alquist-Priolo Earthquake Fault Zone boundary so the potential impact of surface fault rupture is considered less-than-significant. This site is also not at significant risk for impacts related to expansive soils, landslides, or volcanic hazards, does not include mineral resources or unique geologic features and does not propose septic systems. x Greenhouse Gas Emissions: Temporary construction-related exhaust would contribute to GHG emissions as would operation on an on-going basis primarily through consumption of energy for transportation and energy usage. While the emissions were calculated to be below both the operational threshold and conservative annual construction-period thresholds of significance, measures to reduce the construction-period emissions were included as encouraged by the Air District, such as utilizing some alternate-fueled vehicles, locally-sourcing some building materials and recycling/reusing some of the demolition materials and construction waste. x Hazards and Hazardous Materials: The buildings in the OPSP area will meet height limits set for safety under the Airport Land Use Plan for the nearby San Francisco International Airport. The OPSP is not in an area subject to wildfires and the proposed development will not interfere with an adopted emergency response plan. x Hydrology: The site is not in close proximity to a landlocked body of water that could cause inundation by seiche. The site is also nearly level and not bordered by hills which could result in mudflow across the site. The OPSP area is near the shoreline, but avoids development at the fringe area at risk of run up from a tsunami or inundation resulting from climate-change induces sea level rise. The OPSP will not place new structures within the 100-year flood hazard zone or otherwise represent a significant risk of flooding. x Land Use: The OPSP would not divide an established community, would not conflict with plans and policies intended to avoid or mitigate an environmental effect, and would not conflict with a conservation plan. x Noise: The uses proposed as a part of the OPSP have projected noise levels within the standards established by the City of South San Francisco, including intermittent noise from aircraft associated with San Francisco International Airport. Following construction, the OPSP will not create a substantial permanent increase in ambient noise levels at existing uses in the vicinity and would not generate excessive groundborne vibration or groundborne noise levels. x Utilities: Demand for water, stormwater, solid waste services would be met with through service providers and/or on-site improvements, as necessary. Impacts related to increased demand for utilities would be considered less than significant. ALTERNATIVES Three alternatives to the proposed OPSP were considered in detail in the alternatives analysis presented in Chapter 19 of this document, as discussed below. Some alternatives were considered but rejected from further analysis. Given the nature of the OPSP (a Specific Plan for a specific site), the fact that the applicant owns this site and does not intend to develop these uses in another place, an off-site alternative was not feasible. Also, because the types of uses proposed are generally allowed under the existing General Plan designation for the site, and because the OPSP is compliant with TDM program trip reductions, only development intensity was targeted as a parameter that could be changed to affect impacts. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 2-8 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Alternative A: No Project/No Redevelopment Alternative. Alternative A is a “no project” alternative. It assumes the proposed OPSP is not approved and the existing uses remain on the site, and are not redeveloped at higher density. As the only currently vacant area, the portion of the OPSP area to the south of Oyster Point Boulevard and east of Gull Road would reasonably be expected to be developed even without approval of the OPSP. For this analysis, it has been assumed this area would be developed with uses similar to the existing Oyster Point Business Park, consisting of a single-story office/light industrial building of approximately 65,000 square feet. This Alternative assumes no other development and no roadway, recreational, or landfill cap improvements. Alternative B: Reduced Intensity (FAR 1.0) Alternative. Alternative B would allow redevelopment of the OPSP site at an FAR of 1.0 for office/R&D uses. This alternative assumes the same area for office/R&D uses with the same 40/60 split between office and R&D development and similar phasing and parking ratio. The remainder of development, i.e., hotel and recreation fields, would remain the same as that proposed under the OPSP. This alternative would result in the construction of approximately 714,400 square feet of office uses and 1,071,600 square feet of R&D uses, for a total of 1,786,000 square feet of office/R&D development. Buildout under Alternative B would result in approximately 5,000 office/R&D employees on the OPSP site (1,440 less than under the proposed OPSP). Alternative C: Reduced Intensity (FAR 1.12) Alternative. Alternative C would allow redevelopment of the OPSP site at an FAR of 1.12 for the office/R&D areas, with no change to the other planned development (hotel, recreation fields). This alternative assumes the same area for office/R&D uses with the same 40/60 split between office and R&D development and similar phasing and parking ratio. This alternative would result in the construction of approximately 800,110 square feet of office uses and 1,200,165 square feet of R&D uses, for a total of 2,000,275 square feet of office/R&D development. Buildout under Alternative C would result in approximately 5,600 office/R&D employees on the OPSP site (840 less than under the proposed OPSP). Alternatives Conclusion Alternative A, the No Project Alternative would avoid all the identified Significant and Unavoidable impacts under the proposed OPSP. However, benefits identified under the OPSP would not be realized under Alternative A, such as improvements to the landfill cover, remediation of the industrial sumps, protection against sea level rise and provision of recreational areas. Nonetheless, on balance, Alternative A would be the environmentally superior alternative. The other two alternatives, Alternatives B and C, would reduce the amount of development on the site, resulting in roughly 80% or 90% of the trips as would have been generated under the proposed OPSP, respectively. However, although these alternatives would result in some reduction of employees or vehicle trips to the OPSP site, they would not reduce impacts to a degree that would reduce the Significant and Unavoidable impacts to air quality, GHG, noise, and traffic to a less than significant level. Therefore, no analyzed alternative is superior in this regard and, similar to the proposed OPSP, all analyzed alternatives would result in the significant and unavoidable impacts. Additionally, Alternatives B and C may not be economically feasible. They would generate less revenue from private redevelopment. With this reduced revenue, the completion of needed upgrades to the landfill site and upgrades to utilities and infrastructure and the environmental mitigation that would be required for these improvements and any re-development would be in question under Alternatives B and C. CHAPTER 2: EXECUTIVE SUMMARY AND IMPACT OVERVIEW OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 2-9 Table 2.1: Summary of Project Impacts and Mitigation Measures Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance Significant and Unavoidable – No Feasible Mitigation to Reduce to Less Than Significant Impact Air-1: Conflict with Clean Air Plan Assumptions. Development anticipated as a result of the OPSP would increase employment in an area designed for employment centers served by local and regional transit. However, city-wide, vehicle miles traveled (VMT) was projected to increase at a faster rate than the city’s population, which conflicts with CAP assumptions. This is a significant impact. Mitigation Measure Traf-1 would reduce impact Air-1 by requiring implementation of a TDM Plan to reduce trips and VMT. However, the TDM Plan would not likely reduce the number of trips and VMT to an amount that would be assumed under the existing General Plan designation for the site. Thus, this impact would be considered significant and unavoidable. Significant and Unavoidable Impact GHG-2: Operational Greenhouse Gas Emissions. New development in the OPSP area would be an additional source of GHG emissions, primarily through consumption of energy for transportation and energy usage, which could contribute to significant impacts on the environment. This impact is potentially significant. Mitigation Measure Traf-1 and energy efficiency measures included in the project design would reduce this impact. However, since the quantified emissions are above 2010 thresholds, this impact is conservatively determined to be Significant and Unavoidable. Significant and Unavoidable Impact Noise-5: Construction Noise. The OPSP area includes existing sensitive receptors consisting of live-aboard boats in the marinas. In periods of construction, during construction hours, noise generated by construction on the site would substantially increase noise levels at residential land uses in the vicinity of the site temporarily above levels existing without the project. This is a significant impact. Noise-5: Construction Noise. To reduce noise levels generated by construction, the following standard construction noise control measures shall be included in all construction projects within the OPSP area. • Equip all internal combustion engine driven equipment with intake and exhaust mufflers that are in good condition and appropriate for the equipment. • Unnecessary idling of internal combustion engines should be strictly prohibited. • Locate stationary noise generating equipment such as air compressors or portable power generators as far as possible from sensitive receptors. Construct temporary noise barriers to screen stationary noise generating equipment when located near adjoining sensitive receptors. Temporary noise barriers could reduce construction noise levels by 5 dBA. • Utilize "quiet" air compressors and other stationary noise sources where technology exists. • Route all construction traffic to and from the OPSP area via designated truck routes where possible. Prohibit construction related heavy truck traffic in residential areas where feasible. • Control noise from construction workers’ radios to a point that they are not audible at existing residences bordering the OPSP area. • The contractor shall prepare and submit to the City for approval a detailed construction plan identifying the schedule for major noise- generating construction activities. Significant and Unavoidable DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 2-10 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance • Designate a "disturbance coordinator" who would be responsible for responding to any local complaints about construction noise. The disturbance coordinator will determine the cause of the noise complaint (e.g., starting too early, bad muffler, etc.) and will require that reasonable measures warranted to correct the problem be implemented. Conspicuously post a telephone number for the disturbance coordinator at the construction site and include it in the notice sent to neighbors regarding the construction schedule. • For pile driving activities, consider a) pre- drilling foundation pile holes to minimize the number of impacts required to seat the pile, b) using multiple pile driving rigs to expedite this phase of construction, and/or c) the use of “acoustical blankets” for receivers located within 100 feet of the site. Impact Traf-13: Off-Ramp Operation At Mainline Diverge. The following off-ramp diverge location from the U.S.101 freeway mainline would receive a significant impact due to the addition of Phase I Project traffic to year 2015 Base Case volumes (see Table 16.6). • U.S.101 Southbound Flyover Off-Ramp to Oyster Point Boulevard AM Peak Hour: The Phase I Project would increase volumes by 8.2 percent at a location where Base Case diverge volumes would already be exceeding 1,500 vehicles per hour (from 1,618 up to 1,750 VPH). This would be a significant impact. Traf-13: Off-Ramp Operation At Mainline Diverge. • U.S.101 Southbound Flyover Off-Ramp to Oyster Point Boulevard No improvements are feasible to mitigate Phase I Project-specific impacts. The spacing of southbound off-ramp connections to Airport Boulevard and to Oyster Point Boulevard precludes the possibility of providing a second off-ramp lane connection to southbound U.S.101 to serve the Oyster Point Boulevard southbound off-ramp. A second off-ramp lane connection to the freeway mainline would require a long (1,000-foot or longer) deceleration lane with only 300 feet of available space. There is no room for provision of this lane. Significant and Unavoidable Impact Traf-14: Off-Ramp Operation At Mainline Diverge. The following off-ramp diverge location from the U.S.101 freeway mainline would receive a significant impact due to the addition of Phase I Project traffic to year 2015 Base Case volumes (see Table 16.6). • U.S.101 Northbound Off-Ramp to Dubuque Avenue AM Peak Hour: The Phase I Project would increase volumes above the 1,500 VPH limit for single lane off-ramp diverge volumes (from 1,356 up to 1,536 VPH). This would be a significant impact. Traf-14: Improvements for Off-Ramp Operation At Mainline Diverge. (see Figure 23 in Appendix E). • U.S.101 Northbound Off-Ramp to Dubuque Avenue • Provide a second off-ramp lane connection to the U.S.101 mainline. Off-ramp diverge capacity would be increased to at least 2,200 vehicles per hour, which would accommodate the Base Case + Phase I Project AM peak hour volume of 1,536 vehicles per hour. This measure will require the approval of Caltrans. Also, this measure is currently not included in the East of 101 Traffic Impact Fee list. It should be noted that because the improvement is within Caltrans’ jurisdiction, the City of South San Francisco, as lead agency for the project, cannot guarantee that the mitigation will be implemented While it is likely that Caltrans will implement the measure, thereby reducing the impact to a less than significant level, because the measure is beyond the lead agency’s jurisdiction, for CEQA Significant and Unavoidable CHAPTER 2: EXECUTIVE SUMMARY AND IMPACT OVERVIEW OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 2-11 Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance purposes, this impact is considered to be significant and unavoidable. Impact Traf-17: Intersection Level of Service. The following intersection would receive a significant impact due to the addition of OPSP traffic to year 2035 Base Case volumes (see Table 16.16). • Oyster Point Boulevard / Dubuque Avenue / U.S.101 Northbound On-Ramp PM Peak Hour: The OPSP would degrade acceptable (LOS D) Base Case operation to unacceptable (LOS E) operation. This would be a significant impact. Traf-17: Intersection Level of Service. There are no improvements feasible to mitigate the OPSP- specific impacts. Significant and Unavoidable Impact Traf-18: Intersection Level of Service. The following improvements would receive a significant impact due to the addition of OPSP traffic to year 2035 Base Case volumes (see Table 16.16). • Oyster Point Boulevard / Gateway Boulevard / U.S.101 Southbound Flyover Off-Ramp AM Peak Hour: The OPSP would increase volumes by 22.7 percent at a location with unacceptable LOS F Base Case operation. PM Peak Hour: The OPSP would increase volumes by 22.5 percent at a location with unacceptable LOS F Base Case operation. This would be a significant impact. Traf-18: Intersection Level of Service (see Figure 24 in Appendix E). The following improvements would partially mitigate OPSP- specific impacts, but not reduce them to a level of insignificance. Some of these measures are not included as part of the current East of 101 Transportation Improvement Program (TIP). The OPSP shall provide a fair share contribution towards all measures currently not part of the TIP. • Oyster Point Boulevard / Gateway Boulevard / U.S.101 Southbound Flyover Off-Ramp • Adjust signal timing. • Provide an additional through lane on the Oyster Point westbound approach (extending from Veterans Boulevard) and continue to the Dubuque/U.S.101 Northbound On-Ramp intersection. • Restripe the Oyster Point Boulevard eastbound approach from a left, 2 throughs and a combined through/right turn lane to a left, 2 throughs and an exclusive right turn lane. • Restripe the Southbound Flyover Off-Ramp approach from 2 through lanes and an exclusive right turn lane to two through lanes and a combined through/right turn lane. In conjunction with this measure, add a third eastbound departure lane on Oyster Point Boulevard (not part of TIP). • Add a second exclusive right turn lane on the southbound Genentech property driveway approach (not part of TIP). Resultant 2035 Base Case + OPSP Operation: AM Peak Hour: LOS F-194 seconds control delay, which would not be better than Base Case operation (LOS F-124 seconds delay). PM Peak Hour: LOS F-118 seconds control delay, which would not be better than Base Case operation (LOS F-108 seconds delay). Significant and Unavoidable DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 2-12 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance Impact Traf-26: 95th Percentile Vehicle Queuing — Synchro software evaluation. The following off-ramp or approach to an adjacent intersection leading away from an off-ramp would receive a significant queuing impact due to the addition of OPSP traffic to year 2035 Base Case volumes (see Table 16.17). • Oyster Point Blvd. / Gateway Blvd. / U.S.101 Southbound Flyover Off-Ramp AM Peak Hour: The OPSP would increase volumes by 54.6 percent in the through lanes on the Oyster Point Boulevard eastbound approach to Gateway Boulevard and increase the 95th percentile queue above available storage. The 95th percentile vehicle queue would be extended from 756 up to about 1,200 feet with only 900 feet of storage. This would be a significant impact. Mitigation Measure Traf-26: Vehicle Queuing (see Figure 24 in Appendix E). The following improvements would partially mitigate OPSP-specific impacts, but not reduce them to a level of insignificance. These measures are not included as part of the current East of 101 Transportation Improvement Program (TIP). The OPSP shall also provide a fair share contribution towards all measures currently not part of the TIP. • Oyster Point Blvd. / Gateway Blvd. / U.S.101 Southbound Flyover Off-Ramp Adjust signal timing. Provide an additional through lane on the Oyster Point westbound approach (extending from Veterans Boulevard) and continue to the Dubuque/U.S.101 Northbound On-Ramp intersection. Restripe the Oyster Point Boulevard eastbound approach from a left, 2 throughs and a combined through/right turn lane to a left, 2 throughs and an exclusive right turn lane. Restripe the Southbound Flyover Off-Ramp approach from 2 through lanes and an exclusive right turn lane to two through lanes and a combined through/right turn lane. In conjunction with this measure, add a third eastbound departure lane on Oyster Point Boulevard (not part of TIP). Add a second exclusive right turn lane on the southbound Genentech property driveway approach (not part of TIP). Resultant 95th Percentile Vehicle Queuing: AM Peak Hour: Eastbound through 95th percentile queue would be reduced to 1,102 feet, which would not be less than the Base Case queue of 756 feet. Significant and Unavoidable Impact Traf-27: 95th Percentile Vehicle Queuing — Synchro software evaluation. The following off-ramp/approach to an adjacent intersection leading away from an off-ramp would receive a significant queuing impact due to the addition of OPSP traffic to year 2035 Base Case volumes (see Table 16.17). • Oyster Point Boulevard / Dubuque Avenue AM Peak Hour: The OPSP would increase volumes by 14.2 percent in the through lanes on the Oyster Point Boulevard eastbound approach to Dubuque Avenue at a location with Base Case 95th percentile queuing greater than established standards. The eastbound through lane queue would be extended from 586 up to 637 feet at a location with only 250 feet of storage. In addition, the queue lanes on the northbound Dubuque Avenue approach to Oyster Point Boulevard would be increased beyond available Traf-27: Vehicle Queuing.

PM Peak Hour: The OPSP would increase volumes by 21.9 percent on the Oyster Point eastbound approach to Dubuque Avenue at a location with Base Case 95th percentile queuing greater than established standards. The eastbound through lane queue would be extended from 302 up to 376 feet at a location with only 250 feet of storage. This would be a significant impact. Impact Traf-29: Off-Ramp Queuing To Freeway Mainline During Peak Traffic Hours - SIM traffic evaluation. The following off-ramp would receive a significant impact with backups extending to the freeway mainline sometime during one or both peak hours due to the addition of OPSP traffic to year 2035 Base Case volumes. • U.S.101 Northbound Off-Ramp to S. Airport Boulevard / Wondercolor Lane AM Peak Hour: The OPSP would increase volumes on the off-ramp by 2.9 percent at a location with year 2035 Base Case off-ramp traffic occasionally backing up to the freeway mainline. This would be a significant impact. Traf-29: Off-Ramp Queuing. No improvements are feasible to mitigate OPSP- specific impacts.

This would be a significant impact. Traf-30: Vehicle Queuing. No improvements are feasible to mitigate the OPSP-specific impact. Measures recommended in Traf-28 would reduce off-ramp queuing. However, backups would continue to occasionally extend to the freeway mainline during the AM peak hour.

SIM Traffic evaluation The following off-ramp would receive a significant impact with backups extending to the freeway mainline sometime during one or both peak hours due to the addition of OPSP traffic to year 2035 Base Case volumes. • U.S.101 Northbound Off-Ramp to E. Grand Avenue / Executive Drive Intersection AM Peak Hour: The OPSP would increase volumes by 1.7 percent at a location with year 2035 Base Case off-ramp traffic occasionally backing up to the freeway mainline. The primary reason for the backup would be congestion at downstream intersections along E. Grand Avenue. This would be a significant impact. Traf-32: Vehicle Queuing. No improvements are feasible to mitigate the OPSP-specific impact. Significant and Unavoidable Impact Traf-33: Off-Ramp Operation At Mainline Diverge. The analysis concluded that there would be a significant impact at the Southbound Flyover Off-Ramp Diverge to the Oyster Point / Gateway Boulevard intersection due to the addition of OPSP traffic to year 2035 Base Case volumes (see Table 16.6). AM peak hour volumes would be increased by 16.6 percent (from 2,107 up to 2,456 vehicles per hour) at a location where Base Case volumes would already be exceeding the off-ramp diverge capacity of 1,500 vehicles per hour. This would be a significant impact. Traf-33: Improvement to Diverge Capacity – U.S.101 Southbound Flyover Off-Ramp to Oyster Point Boulevard No improvements are feasible to mitigate OPSP- specific impacts. The spacing of southbound off- ramp connections to Airport Boulevard and to Oyster Point Boulevard precludes the possibility of providing a second off-ramp lane connection to southbound U.S.101 to serve the Oyster Point Boulevard southbound off-ramp. A second off-ramp lane connection to the freeway mainline would require a long (1,000-foot or longer) deceleration lane with only 300 feet of available space. There is no room for provision of this lane. Significant and Unavoidable Impact Traf-34: Off-Ramp Operation At Mainline Diverge. The analysis concluded that there would be a significant impact at the Northbound Off-Ramp Diverge to the Dubuque Avenue due to the addition of OPSP traffic to year 2035 Base Case volumes (see Table 16.6). AM peak hour volumes would be increased by 28.7 percent (from 1,556 up to 2,002 vehicles per hour) at a location where Base Case volumes would already be exceeding the off-ramp diverge capacity of 1,500 vehicles per hour. This would be a significant impact. Traf-34: Improvement to Diverge Capacity U.S.101 Northbound Off-Ramp to Dubuque Avenue. The following improvements would mitigate the OPSP-specific impact (see Figure 24 in Appendix E). Provide a second off-ramp lane connection to the U.S.101 mainline. Off-ramp diverge capacity would be increased to at least 2,200 vehicles per hour, which would accommodate the Base Case + OPSP AM peak hour volume of 1,556 vehicles per hour. This measure will require the approval of Caltrans. Also, this measure is currently not included in the East of 101 TIP. Therefore, the OPSP shall provide a fair share contribution towards this measure.

Impact Traf-35: On-Ramp Operation. The analysis concluded that there would be a significant impact at the Northbound On-Ramp from Oyster Point Boulevard / Dubuque Avenue due to the addition of OPSP traffic to year 2035 Base Case volumes (see Table 16.7). PM peak hour volumes would be increased by 17.0 percent (from 2,190 up to 2,563 vehicles per hour) at a location where Base Case volumes would be just less than the on-ramp capacity of 2,200 vehicles per hour. This would be a significant impact. Traf-35: Improvement to On-Ramp Capacity Northbound On-Ramp from Oyster Point Boulevard / Dubuque Avenue (see Figure 24 in Appendix E). Provision of a second on-ramp lane would increase capacity to about 3,000 to 3,100 vehicles per hour. This measure will require the approval of Caltrans. Also, this measure is currently not included in the East of 101 TIP. Therefore, the OPSP shall provide a fair share contribution towards this measure. It should be noted that because the improvement is within Caltrans’ jurisdiction, the City of South San Francisco, as lead agency for the OPSP, cannot guarantee that the mitigation will be implemented While it is likely that Caltrans will implement the measure, thereby reducing the impact to a less than significant level, because the measure is beyond the lead agency’s jurisdiction, for CEQA purposes, this impact is considered to be significant and unavoidable. There are no other physical improvements possible acceptable to Caltrans to accommodate the Base Case + OPSP volume of about 2,563 vehicles per hour. Significant and Unavoidable Impact Traf-36: On-Ramp Operation. The analysis concluded that there would be a significant impact at the Southbound On-Ramp from Dubuque Avenue due to the addition of OPSP traffic to year 2035 Base Case volumes (see Table 16.7). PM peak hour volumes would be increased by 11.5 percent (from 1,906 up to 2,125 vehicles per hour) at a location where Base Case volumes would be just less than the on- ramp capacity of 2,000 vehicles per hour. This would be a significant impact. Traf-36: Improvement to On-Ramp Capacity Southbound On-Ramp from Dubuque Avenue (see Figure 24 in Appendix E). This OPSP should provide a fair share contribution as determined by the City Engineer to the following measure. Provide a second on-ramp lane connection to the U.S.101 freeway. On-ramp capacity would be increased from 2,000 up to 3,000 vehicles per hour, with a Base Case + OPSP PM peak hour volume of about 2,125 vehicles per hour. This measure will require the approval of Caltrans. Also, this measure is currently not included in the East of 101 TIP. Therefore, the OPSP shall provide a fair share contribution towards this measure. It should be noted that because the improvement is within Caltrans’ jurisdiction, the City of South San Francisco, as lead agency for the OPSP, cannot guarantee that the mitigation will be implemented While it is likely that Caltrans will implement the measure, thereby reducing the impact to a less than significant level, because the measure is beyond the lead agency’s jurisdiction, for CEQA purposes, this impact is considered to be significant and unavoidable. Significant and Unavoidable Impact Traf-37: Freeway Mainline Operation. One U.S.101 mainline segments would receive a significant impact due to the addition of OPSP traffic to year 2035 Base Case volumes (see Traf-37: Improvement to Freeway Mainline.

This would be a significant impact. such mitigation is not feasible. Additionally, such mitigation would be prohibitively expensive in relation to the types of land uses it would benefit. Given these specific concerns, mitigation of Impact 14A is not feasible as defined by CEQA. Less than Significant with Mitigation Impact Vis-2: Light and Glare. The many windows and outdoor lights associated with increased development intensity within the OPSP area could potentially be substantial sources of nighttime light and daytime glare. This impact is potentially significant. Vis-2a: Lighting Plan. In order to reduce sources of light and glare created by lighting within the OPSP area, the applicant shall specify fixtures and lighting that maintains appropriate levels of light at building entries, walkways, courtyards, parking lots and private roads at night consistent with minimum levels detailed in the City’s building codes. These fixtures shall be designed to eliminate spillover, high intensity, and unshielded lighting, thereby avoiding unnecessary light pollution. Prior to issuance of building permits for each phase of construction within the OPSP, the applicant shall submit a Lighting Design Plan for review and approval by the City of South San Francisco Planning Department. The plan shall include, but not necessarily be limited to the following: • The Lighting Design Plan shall disclose all potential light sources with the types of lighting and their locations. • Typical lighting shall include low mounted, downward casting and shielded lights that do not cause spillover onto adjacent properties and the utilization of motion detection systems where applicable. • No flood lights shall be utilized. • Lighting shall be limited to the areas that would be in operation during nighttime hours. • Low intensity, indirect light sources shall be encouraged. • On-demand lighting systems shall be encouraged. • Mercury, sodium vapor, and similar intense and bright lights shall not be permitted except where their need is specifically approved and their source of light is restricted. • Generally, light fixtures shall not be located at the periphery of the property and should shut off automatically when the use is not operating. Security lighting visible from the highway shall be motion-sensor activated. • Use “cut-off” fixtures designed to prevent the Less than Significant CHAPTER 2: EXECUTIVE SUMMARY AND IMPACT OVERVIEW OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 2-17 Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance upward cast of light and avoid unnecessary light pollution where appropriate. • All lighting shall be installed in accordance with the building codes and the approved lighting plan during construction. Vis-2b: Glare Reduction. In order to reduce sources of daytime glare created by reflective building materials, the applicant shall specify exterior building materials for all proposed structures constructed for the Phase I Project and each subsequent phase of development under the OPSP that include the use of textured or other non- reflective exterior surfaces and non-reflective glass types, including double glazed and non-reflective vision glass. These materials shall be chosen for their non-reflective characteristics and their ability to reduce daytime glare. All exterior glass must meet the specifications of all applicable codes for non-reflective glass and would therefore reduce daytime glare emanating from the OPSP area. Impact Air-2: Possible Exposure of Sensitive Receptors to TACs and PM2.5. Development anticipated under the OPSP may expose sensitive receptors to TACs and PM2.5 through development of new non-residential development that may be sources of TACs and PM2.5 and the potential for development of ancillary uses, such as daycare facilities, that would bring sensitive users to the site. Such exposure would represent a potentially significant impact. Air-2: Health Risk Assessment for Proposed Sensitive Receptors. New projects within the OPSP area that would include sensitive receptors (e.g., daycare centers) shall analyze TAC and PM2.5 impacts and include mitigation measures to reduce exposures to less than significant levels. The following measures could be utilized in site planning and building designs to reduce TAC exposure: • New development of sensitive receptors located within OPSP area shall require site specific analysis to determine the level of TAC and PM2.5 exposure. This analysis shall be conducted following procedures outlined by BAAQMD. If the site specific analysis reveal significant exposures, based on BAAQMD guidance, then additional measures listed below shall be required. • Where exterior exposures are significant, consider site planning to buffer new sensitive receptors from TAC emissions. Active site uses and building air intakes shall be situated away from TAC sources • Provide tiered plantings of vegetation along the site boundaries closest to TAC sources. Preliminary laboratory studies show that redwood and/or deodar cedar trees can remove some of the fine particulate matter emitted from traffic under low wind speeds. Low wind speeds typically result in the highest particulate matter concentrations. Less than Significant Impact Air-4: Construction Period Dust, Emissions and Odors.

Without appropriate measures to control these emissions, these impacts would be considered significant. construction are recommended to ensure that short-term health impacts to nearby sensitive receptors are avoided. Dust (PM10) Control Measures: • Water all active construction areas at least twice daily and more often during windy periods. Active areas adjacent to residences should be kept damp at all times. • Cover all hauling trucks or maintain at least two feet of freeboard. • Pave, apply water at least twice daily, or apply (non-toxic) soil stabilizers on all unpaved access roads, parking areas, and staging areas. • Sweep daily (with water sweepers) all paved access roads, parking areas, and staging areas and sweep streets daily (with water sweepers) if visible soil material is deposited onto the adjacent roads. • Hydroseed or apply (non-toxic) soil stabilizers to inactive construction areas (i.e., previously- graded areas that are inactive for 10 days or more). • Enclose, cover, water twice daily, or apply (non- toxic) soil binders to exposed stockpiles. • Limit traffic speeds on any unpaved roads to 15 mph. • Replant vegetation in disturbed areas as quickly as possible. • Suspend construction activities that cause visible dust plumes to extend beyond the construction site. • Post a publically visible sign(s) with the telephone number and person to contact at the Lead Agency regarding dust complaints. This person shall respond and take corrective action within 48 hours. The Air District’s phone number shall also be visible to ensure compliance with applicable regulations. Additional Measures to Reduce Diesel Particulate Matter and PM2.5 and other construction emissions: • The developer or contractor shall provide a plan for approval by the City or BAAQMD demonstrating that the heavy-duty (>50 horsepower) off-road vehicles to be used in the construction project, including owned, leased and subcontractor vehicles, will achieve a project wide fleet-average 20 percent NOx reduction and 45 percent particulate reduction compared to the most recent CARB fleet average for the year 2011 • Clear signage at all construction sites will be posted indicating that diesel equipment standing idle for more than five minutes shall be turned CHAPTER 2: EXECUTIVE SUMMARY AND IMPACT OVERVIEW OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 2-19 Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance off. This would include trucks waiting to deliver or receive soil, aggregate, or other bulk materials. Rotating drum concrete trucks could keep their engines running continuously as long as they were onsite or adjacent to the construction site. • Opacity is an indicator of exhaust particulate emissions from off-road diesel powered equipment. Each project shall ensure that emissions from all construction diesel powered equipment used on the project site do not exceed 40 percent opacity for more than three minutes in any one hour. Any equipment found to exceed 40 percent opacity (or Ringelmann 2.0) shall be repaired immediately • The contractor shall install temporary electrical service whenever possible to avoid the need for independently powered equipment (e.g. compressors). • Properly tune and maintain equipment for low emissions. Air-4b: Implement Odor-Control Measures During Refuse Relocation. The following measures shall be implemented during disturbance of the landfill for refuse relocation: • All areas shall remain under foundation layer cover until localized refuse relocation occurs. • Limit the horizontal area of opened foundation layer to at most an acre of horizontal area at any one time per area (an acre for the area being excavated and an acre for the area where trash is being relocated). • Excavation and fill zones shall be covered at the end of each day, either with secured tarping or with the foundation layer of soil. • Additional measures for odor control such as a foam cover or scented misters in active areas and/or covering of the materials in the haul trucks may be considered and implemented based upon actual field conditions. • Post a publically visible sign(s) with a 24-hour contact number for odor complaints. The Air District’s phone number shall also be visible to ensure compliance with applicable regulations. Concerns/complaints related to odor from the work will be evaluated and protocol measures will be amended as necessary. • If 10 or more complaints are logged with BAAQMD within a 90-day period, BAAQMD will have regulatory authority that supersedes this mitigation measure consistent with BAAQMD Regulation 7. Impact Bio-2: Disturbance or Loss of Wetland or Aquatic Habitats. Development of the OPSP Bio-2a: Delineate Jurisdictional Boundaries.

Due to the ecological importance of wetland and aquatic habitats, such impacts would be potentially significant. elements that are expected to potentially have direct impacts on USACE jurisdictional habitats, a focused delineation shall be performed to determine the precise limits of USACE jurisdiction at the site, and USACE approval of the jurisdictional boundaries will be obtained. Bio- 2b: Impact Avoidance/Minimization. Future OPSP elements near the Bay shoreline shall be designed with consideration of the boundaries of sensitive wetland and aquatic habitats in order to avoid and minimize impacts to these sensitive habitats to the extent practicable while still accomplishing OPSP objectives. For example, building and trail construction, landscaping activities, and other terrestrial activities shall be planned and designed to avoid impacting the sensitive habitats near the Bay shoreline to the extent feasible. For activities that cannot avoid impacting sensitive habitats due to their water- related purpose or location, such as construction or replacement of piers or docks in the marina, the amount of new fill or the footprint of new structures placed in or on the water shall be limited to the minimum necessary to achieve the objectives of that component. The City shall review plans for any proposed activities that will result in impacts to sensitive wetland and aquatic habitats to ensure that impacts have been avoided and minimized to the extent feasible. Bio-2c: Restoration of Temporarily Impacted Wetland/Aquatic Habitats. USACE-jurisdictional areas that are temporarily impacted during construction of programmatic elements shall be restored to preexisting contours and levels of soils compaction following build-out. The means by which such temporarily impacted areas will be restored shall be described in the mitigation plan described in Measure 2d below. Bio-2d: Compensation for Permanently Impacted Wetland/Aquatic Habitats. Unavoidable permanent fill of all habitats within USACE jurisdiction shall be replaced at a minimum 1:1 (mitigation area: impact area) ratio by creation or restoration of similar habitat around San Francisco Bay. Any aquatic, marsh, or mudflat habitat areas experiencing a net increase in shading as a result of docks or other structures constructed over or on the water shall require compensatory mitigation at a 0.5:1 (mitigation area: impact area) ratio; this ratio is less than the 1:1 required for permanent filling of such habitats because shaded areas are expected to retain some ecological habitat value. Mitigation could be achieved through a combination of on-site restoration or creation of wetlands or aquatic habitats (including removal of on-site fill or structures, resulting in a gain of wetland or aquatic CHAPTER 2: EXECUTIVE SUMMARY AND IMPACT OVERVIEW OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 2-21 Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance habitats); off-site restoration/creation; funding of off-site restoration/creation projects implemented by others; and/or mitigation credits purchased at mitigation banks within the San Francisco Bay Region. Because impacts to aquatic habitats on-site could also potentially impact special-status fish and EFH (see Impacts to Essential Fish Habitat and Special-Status Fish below), all compensatory mitigation for impacts to aquatic habitat must also provide habitat for green sturgeon, Central California Coast steelhead, and longfin smelt that is of a quality at least as high as that impacted. For funding of off-site improvements or purchase of mitigation bank credits, the OPSP Applicant shall provide written evidence to the City that either (a) compensation has been established through the purchase of a sufficient number of mitigation credits in a mitigation bank to satisfy the mitigation acreage requirements of the OPSP activity, or (b) funds sufficient for the restoration of the mitigation acreage requirements of the OPSP activity have been paid to an entity implementing a project that would create or restore habitats of the type being impacted by the OPSP. For areas to be restored to mitigate for temporary or permanent impacts, the OPSP Applicant shall prepare and implement a mitigation plan. The OPSP Applicant shall retain a restoration ecologist or wetland biologist to develop the mitigation plan, and it shall contain the following components (or as otherwise modified by regulatory agency permitting conditions): 1. Summary of habitat impacts and proposed mitigation ratios, along with a description of any other mitigation strategies used to achieve the overall mitigation ratios, such as funding of off- site improvements and/or purchase of mitigation bank credits 2. Goal of the restoration to achieve no net loss of habitat functions and values 3. Location of mitigation site(s) and description of existing site conditions 4. Mitigation design: • Existing and proposed site hydrology • Grading plan if appropriate, including bank stabilization or other site stabilization features • Soil amendments and other site preparation elements as appropriate • Planting plan • Irrigation and maintenance plan • Remedial measures/adaptive management, etc. 5. Monitoring plan (including final and performance criteria, monitoring methods, data DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 2-22 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance analysis, reporting requirements, monitoring schedule, etc.) 6. Contingency plan for mitigation elements that do not meet performance or final success criteria. Impact Bio-3: Construction-Period Increases in Turbidity. Sediment may wash from construction areas into adjacent aquatic habitats, or soil loosened by grading could slide downslope into such areas. Increases in turbidity resulting from construction constitutes a potentially significant impact to aquatic wildlife species, including special-status fish species such as steelhead and sensitive native species such as the Olympia oyster. Water quality degradation could also negatively impact eelgrass beds if they occur in the OPSP area. Due to the ecological importance of these aquatic habitats and sensitive resources, such impacts would be potentially significant. Bio-3a: Incorporate Best Management Practices for Water Quality During Construction. The Plan shall incorporate Best Management Practices (BMPs) for water quality to minimize impacts in the surrounding wetland environment, sloughs and channels, and the San Francisco Bay during construction. These BMPs shall include numerous practices that will be outlined within the Stormwater Pollution Prevention Plan (SWPPP), including, but not limited to, the following mitigation measures: 1. No equipment will be operated in live flow in any of the sloughs or channels or ditches on or adjacent to the site. 2. No debris, soil, silt, sand, bark, slash, sawdust, cement, concrete, washings, petroleum products or other organic or earthen material shall be allowed to enter into or be placed where it may be washed by rainfall or runoff into aquatic or wetland habitat. 3. Standard erosion control and slope stabilization measures will be required for work performed in any area where erosion could lead to sedimentation of a waterbody. For example, silt fencing will be installed just outside the limits of grading and construction in any areas where such activities will occur upslope from, and within 50 ft of, any wetland, aquatic, or marsh habitat. This silt fencing will be inspected and maintained regularly throughout the duration of construction. 4. Machinery will be refueled at least 50 ft from any aquatic habitat, and a spill prevention and response plan will be developed. All workers will be informed of the importance of preventing spills and of the appropriate measures to take should a spill occur. Bio-3b: Minimize Soil Disturbance Adjacent to Wetland and Marsh Habitat. To the extent feasible, soil stockpiling, equipment staging, construction access roads, and other intensively soil-disturbing activities shall not occur immediately adjacent to any wetlands that are to be avoided by the OPSP. The limits of the construction area shall be clearly demarcated with Environmentally Sensitive Area fencing to avoid inadvertent disturbance outside the fence during construction activities. Less than Significant Impact Bio-4: Operational Stormwater Impacts on Wetlands and a Tidal Channel. Installation of stormwater outfalls from the buildings to be constructed in the southwestern part of the site Bio-4: Ensure Adequate Stormwater Run-off Capacity. Increases in stormwater run-off due to increased hardscape shall be mitigated through the construction and maintenance of features designed Less than Significant CHAPTER 2: EXECUTIVE SUMMARY AND IMPACT OVERVIEW OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 2-23 Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance shall outfall into vegetated swales that are to be constructed just upslope from the wetlands and tidal channel that form the southwestern boundary of the site. If these swales are not adequately constructed, there is some potential for excessive erosion or the release of untreated runoff into these wetlands and tidal waters. Due to the value of wetland habitats to the ecology of the Bay’s aquatic habitats and the value of these aquatic habitats to a variety of fish, benthic organisms, and other species, degradation of water quality or wetlands would be a potentially significant impact. to handle the expected increases in flows and provide adequate energy dissipation. All such features, including outfalls, shall be regularly maintained to ensure continued function and prevent failure following construction. Impact Bio-6: Disturbance of Special-Status Nesting Birds. Construction-related noise and activity could disturb or displace special-status breeding birds. The number of nesting individuals that could be disturbed is very small, and the OPSP’s impacts would not substantially reduce regional populations of special-status bird species, and thus these impacts do not meet the CEQA standard of having a substantial adverse effect on these species. However, the loss of any active nests of protected birds would be in violation of federal and state laws, thus this impact would be considered potentially significant. Bio-6: Pre-Construction Nesting Bird Survey. Pre-construction surveys for nesting birds protected by the Migratory Bird Treaty Act of 1918 and/or Fish and Game Code of California within 100 feet of a development site in the OPSP area shall be conducted if construction commences during the avian nesting season, between February 1 and August 31. The survey should be undertaken no more than 15 days prior to any site-disturbing activities, including vegetation removal or grading. If active nests are found, a qualified biologist shall determine an appropriate buffer in consideration of species, stage of nesting, location of the nest, and type of construction activity. The buffers should be maintained until after the nestlings have fledged and left the nest. Less than Significant Impact Bio-7: Construction-Period Disturbance of Burrowing Owls. Burrowing owls could potentially burrow in grassland habitats and/or use crevices in shoreline riprap as temporary refugia. Due to the marginal nature of habitat on the site, and the current lack of suitable breeding sites in the form of ground squirrel burrows, the OPSP will not result in a significant loss of burrowing owl habitat. Nevertheless, any loss of burrowing owls or fertile eggs, any activities resulting in nest abandonment, or the destruction of occupied burrowing owl burrows would constitute a potentially significant impact under CEQA due to the regional rarity of the species and declining nature of its populations. Bio-7a: Pre-construction Burrowing Owl Surveys. Pre-construction surveys for burrowing owls shall be completed in potential habitat in conformance with the California Burrowing Owl Consortium protocol, no more than 30 days prior to the start of construction. If no burrowing owls are located during these surveys, no additional action would be warranted. However, if burrowing owls are located on or immediately adjacent to the site, mitigation measures Bio-7b and Bio-7c shall be implemented. Bio-7b: Buffer Zones. For burrowing owls present during the non-breeding season (generally 1 September to 31 January), a 150-ft buffer zone shall be maintained around the occupied burrow(s) if practicable. If such a buffer is not practicable, then a buffer adequate to avoid injury or mortality of owls shall be maintained, or the birds shall be evicted as described for Mitigation Measures Bio-7c, below. During the breeding season (generally 1 February to 31 August), a 250-ft buffer, within which no new activity shall be permissible, shall be maintained between OPSP activities and occupied burrows. Owls present on site after 1 February shall be assumed to be nesting unless evidence indicates otherwise. This protected buffer area shall remain in effect until 31 August, or based upon monitoring Less than Significant DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 2-24 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance evidence, until the young owls are foraging independently or the nest is no longer active. Bio-7c: Passive Relocation. If construction will directly impact occupied burrows, eviction of owls should occur outside the nesting season to prevent injury or mortality of individual owls. No burrowing owls shall be evicted from burrows during the nesting season (1 February through 31 August) unless evidence indicates that nesting is not actively occurring (e.g., because the owls have not yet begun nesting early in the season, or because young have already fledged late in the season). Relocation of owls during the non-breeding season shall be performed by a qualified biologist using one-way doors, which should be installed in all burrows within the impact area and left in place for at least two nights. These one-way doors shall then be removed and the burrows backfilled immediately prior to the initiation of grading. Impact Bio-10: Increased Potential for Bird Strikes. Relative to the height of the existing structures, several of the OPSP’s proposed buildings will project higher, creating new, somewhat larger obstacles along the flight path of migrating and foraging birds. Therefore, the OPSP could result in the creation of a new strike hazard for migrating. Although large-scale injury or mortality of birds due to collisions with buildings is not anticipated, because of the potential for such mortality to occur, the OPSP is considered to have a potentially significant impact to migratory birds. Bio-10a: Lighting Measures to Reduce Impacts to Birds. During design of any building greater than 100 feet tall, the OPSP Applicant shall consult with a qualified biologist experienced with bird strikes and building/lighting design issues to identify lighting-related measures to minimize the effects of the building’s lighting on birds. Such measures, which may include the following and/or other measures, shall be incorporated into the building’s design and operation. • Use strobe or flashing lights in place of continuously burning lights for obstruction lighting. Use flashing white lights rather than continuous light, red light, or rotating beams. • Install shields onto light sources not necessary for air traffic to direct light towards the ground. • Extinguish all exterior lighting (i.e., rooftop floods, perimeter spots) not required for public safety. • When interior or exterior lights must be left on at night, the operator of the buildings shall examine and adopt alternatives to bright, all-night, floor- wide lighting, which may include: • Installing motion-sensitive lighting. • Using desk lamps and task lighting. • Reprogramming timers. • Use of lower-intensity lighting. • Windows or window treatments that reduce transmission of light out of the building shall be implemented to the extent feasible. Bio-10b: Building Design Measures to Minimize Bird Strike Risk. During design of any building greater than 100 feet tall, the OPSP Applicant shall Less than Significant CHAPTER 2: EXECUTIVE SUMMARY AND IMPACT OVERVIEW OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 2-25 Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance consult with a qualified biologist experienced with bird strikes and building/lighting design issues to identify measures related to the external appearance of the building to minimize the risk of bird strikes. Such measures, which may include the following and/or other measures, shall be incorporated into the building’s design. • Use non-reflective tinted glass. • Use window films to make windows visible to birds from the outside. • Use external surfaces/designs that “break up” reflective surfaces rather than having large, uninterrupted areas of surfaces that reflect, and thus may not appear noticeably different (to a bird) from, the sky. Impact Bio-12: In-Water Construction Impacts on Essential Fish Habitat. Special-status fish species that occur in the OPSP vicinity and could potentially be impacted by in-water construction activities are the southern green sturgeon, the Central California Coast steelhead, and the longfin smelt. Habitat for occasional dispersing individuals of all three species is similarly located in open waters and estuarine habitats of the San Francisco Bay along the boundaries of the OPSP area. This is a potentially significant impact. Bio-12: Measures to Reduce Impacts on Essential Fish Habitat. The following mitigation measures, adapted from Amendment 11 of the West Coast Groundfish Plan (PFMC 2006) and Appendix A of the Pacific Coast Salmon Plan (PFMC 2003), shall be implemented during in-water construction activities unless modified by the federal permitting agencies (NMFS or USACE). Avoidance of Salmonid Migration Periods. In-water work when juvenile salmonids are moving through the Bay on the way to the open ocean or when groundfish and prey species could be directly impacted shall be avoided. Because steelhead are potentially present, the allowed dredge window for this area of the San Francisco Bay is June 1 through November 30. All in-water construction shall occur during this window. If completion of in-water work within this period is not feasible due to scheduling issues, new timing guidelines shall be established and submitted to the NMFS and CDFG for review and approval. Worker Training. Personnel involved in in-water construction and deconstruction activities shall be trained by a qualified biologist in the importance of the marine environment to special-status fish, and birds and the environmental protection measures put in place to prevent impacts to these species, their habitats, and EFH. The training shall include, at a minimum, the following: 1. A review of the special-status fish and sensitive habitats that could be found in work areas 2. Measures to avoid and minimize adverse effects to special-status fish, birds, their habitats, and EFH 3. A review of all conditions and requirements of environmental permits, reports, and plans (i.e., USACE permits) Avoidance of Areas of Wetland and Aquatic Vegetation. All construction equipment used in conjunction with in-water work (pipelines, barges, Less than Significant DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 2-26 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance cranes, etc.) shall avoid wetlands, marshes, and areas of sub-aquatic vegetation (including eelgrass beds). Mitigation Measure Bio-3a would also reduce impact Bio-12 through implementation of Best Management Practices for water quality during construction. Impact Bio-13: Percussive In-Water Construction Noise and Special-Status Fish. If in- water construction is undertaken and includes jackhammering, pile-driving or other in-water percussive activities, pressure waves could cause negative behavioral, psychological and physiological effects that could disturb, injure or kill special-status fish or marine mammals. Due to the number of fish that could be present near in-water construction areas, the potential presence of special-status fish, and the sensitivity of marine mammals such as harbor seals and California sea lions, such impacts are potentially significant. Bio-13a: Incorporation of Design Considerations that Minimize the Need for Percussive Construction Techniques. If programmatic OPSP elements after the Phase I Project include in-water construction of structures that require percussive techniques, structure design shall adhere to the following principles to the greatest extent practicable: 1. Engineer structures to use fewer or smaller piles, where feasible, and preferably, solid piles 2. Design structures that can be installed in a short period of time (i.e., during periods of slack tide when fish movements are lower). 3. The City, with consultation from a qualified biologist who is familiar with marine biology, shall review the final plan design to ensure that these design requirements have been incorporated into the plan. Bio-13b: Utilization of Construction Tools and Techniques that Minimize Percussive Noise. If programmatic OPSP elements include construction of structures that require percussive techniques, construction activities shall employ the following techniques to the greatest extent practicable. 1. Drive piles with a vibratory device instead of an impact hammer if feasible, and use a cushioning block between the hammer and the pile. 2. Restrict driving of steel piles to the June 1 to November 30 work window, or as otherwise recommended by the NMFS (driving of concrete piles would not be subject to this condition). 3. If steel piles must be driven with an impact hammer, an air curtain shall be installed to disrupt sound wave propagation, or the area around the piles being driven shall be dewatered using a coffer dam. The goal of either measure is to disrupt the sound wave as it moves from water into air. 4. If an air curtain is used, a qualified biologist shall monitor pile driving to ensure that the air curtain is functioning properly and OPSP- generated sound waves do not exceed the threshold of 180183-decibels generating 1 micropascal (as established by NMFS guidelinesthe Fisheries Hydroacoustic Working Group; 2008). This shall require monitoring of in-water sound waves during pile driving. Less than Significant CHAPTER 2: EXECUTIVE SUMMARY AND IMPACT OVERVIEW OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 2-27 Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance 5. Use of fewer piles, or smaller piles, or a different type of pile, with hollow steel piles appearing to create the most impact at a given size 6. Driving piles when species of concern are absent 7. Use of a vibratory hammer rather than an impact hammer 8. Use of a cushioning block between hammer and pile 9. Use of a confined or unconfined air bubble curtain; and 10. Driving piles during periods of reduced currents Impact Bio-14: In-Water Construction Disturbance of Olympia Oyster Beds. There is a known population of Olympia oysters at Oyster Point. In-water construction activities, including activities at the marina and along the shoreline, could potentially impact oysters through the removal of substrate supporting oysters, smothering of oyster beds with fill, or degradation of water quality. Such oysters, including their larvae, provide food, refugia, and attachment sites for a number of aquatic organisms and filter nutrients and pollutants from the water. As a result, these oysters perform a valuable function to the Bay ecosystem, and impacts to oysters from in-water construction activities are potentially significant. Bio-14a: Avoidance of Suitable Oyster Habitat. To the greatest extent practicable, OPSP activities shall avoid removing or disturbing riprap and other rocky substrates that serve as suitable oyster habitat. If impacts to oysters and their habitat are unavoidable, measures Bio-14b and Bio-14c shall be implemented. Bio-14b: Native Oyster Surveys. A detailed survey for native oysters shall be conducted in all suitable substrates within the OPSP area. This survey shall be conducted by a qualified oyster biologist at low tides that expose the maximum amount of substrate possible. Surveys can be conducted at any time of year, but late summer and early fall are optimal because newly settled oysters are detectable. This survey shall occur before any construction within aquatic habitats takes place to establish a baseline condition. If few or no oysters are observed on hard substrates that would remain in place after construction, no further mitigation is required. Bio-14c: Replacement of Suitable Oyster Habitat. If more than 100 oysters would be removed or are in areas where construction-generated sediment could settle out onto the oysters, compensatory mitigation shall be provided by the OPSP Applicant at a minimum 1:1 ratio. The OPSP Applicant shall retain a qualified oyster biologist to develop an Oyster Restoration Plan that shall be reviewed and approved by the City. This Plan shall include site selection, substrate installation, and monitoring procedures, and include the following components (unless otherwise modified by NMFS): 1. A suitable site for installation of replacement substrate would be one with adequate daily tidal flow, a location that would not be affected by maintenance dredging or other routine marina maintenance activities, and one that is lacking in appropriate settlement substrate. A location outside of the breakwaters or in association with any eelgrass mitigation sites would be appropriate. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 2-28 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance 2. Although oysters may settle on a variety of materials, the most appropriate for restoration purposes is oyster shell. This is typically installed by placing the shell into mesh bags that can then be placed in piles on the seafloor of the mitigation site. Enough shell shall be installed under the guidance of a qualified oyster biologist to make up for the loss attributable to the OPSP. Mitigation shall occur after construction of all in-water elements of the OPSP. 3. The restoration site shall be monitored on a regular basis by a qualified oyster biologist for a minimum of two years, or until success criteria are achieved if they are not achieved within two years. Monitoring shall involve routine checks (bi-monthly during the winter and monthly during the spring and summer) to evaluate settlement, growth, and survival on the mitigation site. Success shall be determined to have been achieved when settlement and survival rates for oysters are not statistically significantly different between the mitigation site and the populations being impacted. Mitigation Measure Bio-3a would also reduce impact Bio-14 through implementation of Best Management Practices for water quality during construction. Impact Bio-15: Increased Turbidity During In-Water Construction and Eelgrass Beds. In- water construction activities that result in increased turbidity could potentially result in adverse effects to eelgrass by covering eelgrass with sediment. Because eelgrass beds provide nursery habitat for a variety of fish species, they are very important to the Bay ecosystem, and impacts to eelgrass beds are thus potentially significant. Bio-15a: Water Quality Best Management Practices for Eelgrass. In addition to the water quality BMPs described above in Measure Bio-3a, the following BMPs shall minimize impacts to any eelgrass beds in the OPSP area. 1. Conduct all in-water work during periods of eelgrass dormancy (November 1-March 31) [Note: the majority of this period conflicts with the period during which in-water activities should not occur to avoid impacts to salmonids; only the period November 1-30 would avoid impacts during sensitive periods for both taxa.] 2. Install sediment curtains around the worksite to minimize sediment transport If these BMPs are not feasible, or if OPSP activities will occur in aquatic areas outside of the marina, mitigation measures 15b and 15c shall be undertaken. Bio-15b: Eelgrass Survey. Prior to any construction activities in aquatic habitats, a survey for eelgrass beds or patches shall be conducted within 750 ft of expected aquatic construction activities. The survey shall be conducted by a biologist(s) familiar with eelgrass identification and ecology and approved by NMFS to conduct such a survey. Survey methods shall employ either SCUBA or sufficient grab samples to ensure that the Less than Significant CHAPTER 2: EXECUTIVE SUMMARY AND IMPACT OVERVIEW OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 2-29 Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance bottom was adequately inventoried. The survey shall occur between August and October and collect data on eelgrass distribution, density, and depth of occurrence for the survey areas. The edges of any eelgrass beds or patches shall be mapped. At the conclusion of the survey a report shall be prepared documenting the survey methods, results, and eelgrass distribution, if any, within the survey area. This report shall be submitted to NMFS for approval. If OPSP activities can be adjusted so that no direct impacts to eelgrass beds would occur, no further mitigation would be required. If direct impacts to eelgrass beds cannot be avoided, the following measures shall be implemented. Bio-15c: Compensatory Eelgrass Mitigation. If direct impacts to eelgrass beds cannot be avoided, compensatory mitigation shall be provided in conformance with the Southern California Eelgrass Mitigation Policy. Mitigation shall entail the replacement of impacted eelgrass at a 3:1 (mitigation: impact) ratio on an acreage basis, based on the eelgrass mapping described in mitigation measure 8B above, and detailed designs of the feature(s) that would impact eelgrass beds. Such mitigation could occur either off site or on site (NMFS 2005b). Off-site mitigation could be achieved through distribution of a sufficient amount of funding to allow restoration or enhancement of eelgrass beds at another location in the Bay. If this option is selected, all funds shall be distributed to the appropriate state or federal agency or restoration-focused non-governmental agency (i.e., CDFG restoration fund, California Coastal Conservancy, Save the Bay, etc). The OPSP Applicant shall provide written evidence to the City that either a) compensation has been established through the purchase of a sufficient number of mitigation credits to satisfy the mitigation acreage requirements of the OPSP activity, or funds sufficient for the restoration of the mitigation acreage requirements of the OPSP activity have been paid. These funds shall be applied only to eelgrass restoration within the Bay. If on-site mitigation is selected as the appropriate option, the OPSP Applicant shall retain a qualified biologist familiar with eelgrass ecology to prepare and implement a detailed Eelgrass Mitigation Plan. Unless otherwise directed by NMFS, the Eelgrass Mitigation Plan shall follow the basic outline and contain all the components required of the Southern California Eelgrass Mitigation Policy (as revised in 2005), including: identification of the mitigation need, site, transplant methodology, mitigation extent (typically 3:1 on an acreage basis), monitoring protocols (including frequency, staffing, reviewing agencies, duration, etc), and success criteria. A draft Eelgrass Mitigation Plan shall be submitted to DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 2-30 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance NMFS, for its review and approval prior to implementation, with a copy to the City. Once the plan has been approved, it shall be implemented in the following appropriate season for transplantation. Restored eelgrass beds shall be monitored for success over a 5-year period. Mitigation Measure Bio-3a would also reduce impact Bio-15 through implementation of Best Management Practices for water quality during construction. Impact Culture-1: Disturbance of Unidentified Paleontological Resources, Archaeological Resources or Human Remains. During earth- moving activities at the OPSP site, it is possible that unidentified paleontological resources, archaeological resources or human remains could be uncovered and disturbed. Culture-1a: Halt Construction Activity, Evaluate Find and Implement Mitigation. In the event that any previously unidentified paleontological or archaeological resources are uncovered during site preparation, excavation or other construction activity, all such activity shall cease until these resources have been evaluated by a qualified paleontologist or archaeologist and specific mitigation measures can be implemented to protect these resources. Culture-1b: Halt Construction Activity, Evaluate Find and Take Appropriate Action in Coordination with Native American Heritage Commission. In the event that any human remains are uncovered during site preparation, excavation or other construction activity, all such activity shall cease until these resources have been evaluated by the County Coroner, and appropriate action taken in coordination with the Native American Heritage Commission. Less than Significant Impact Geo-2: Seismic Ground Shaking. There is a high probability that the proposed development will be subjected to strong to violent ground shaking from an earthquake during its design life. Strong to violent seismic ground shaking is considered a potentially significant impact. Geo-2a: Compliance with California Building Code. OPSP development shall meet requirements of the California Building Code, including the California Building Standards, published by the International Conference of Building Officials, and as modified by the amendments, additions and deletions as adopted by the City of South San Francisco, California. Incorporation of seismic construction standards will reduce the potential for catastrophic effects of ground shaking, such as complete structural failure, but will not completely eliminate the hazard of seismically induced ground shaking. Geo-2b: Compliance with a design-level Geotechnical Investigation report prepared by a Registered Geotechnical Engineer and with Structural Design Plans as prepared by a Licensed Professional Engineer. Proper foundation engineering and construction shall be performed in accordance with the recommendations of a Registered Geotechnical Engineer and a Licensed Professional Engineer. The structural engineering design, with supporting Geotechnical Investigation, shall incorporate seismic parameters compliant with the California Building Code. Less than Significant CHAPTER 2: EXECUTIVE SUMMARY AND IMPACT OVERVIEW OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 2-31 Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance Geo-2c: Obtain a building permit. The OPSP applicant shall obtain a building permit through the City of South San Francisco Building Division. Plan Review of planned buildings and structures shall be completed by the Building Division for adherence to the seismic design criteria for planned commercial and industrial sites in the East of 101 area of the City of South San Francisco. According to the East of 101 area plan, Geotechnical Safety Element, buildings shall not be subject to catastrophic collapse under foreseeable seismic events, and will allow egress of occupants in the event of damage following a strong earthquake. Impact Geo-3. Liquefaction, Densification, and Ground Surface Settlement. The Association of Bay Area Governments identifies the OPSP area as an area of high hazard for liquefaction. However, based on the subsurface data obtained from the previous drilled borings at Oyster Point (noted above among the references reviewed), the existing landfill materials, residual soils, Bay Mud, and Franciscan Complex bedrock have a low potential for liquefaction. Therefore, damage due to liquefaction at Oyster Point is considered low. It should be noted that the landfill is contained by soil dikes along the water-side site perimeter. These perimeter dikes are reported to have been constructed of Bay Mud, which has low potential for liquefaction. Prior to new site development, geotechnical studies shall be undertaken to confirm the material types used in the construction of the perimeter dikes to verify the assumed low potential for liquefaction. Liquefaction or densification of soils composing or underlying the perimeter dikes could result in settlement and differential settlement of site improvements including buildings, pavements, and utilities and pose a threat to human health. The potential for liquefaction of perimeter dike soils is considered a potentially significant impact. Geo-3a: Compliance with recommendations of a Geotechnical Investigation and in conformance with Structural Design Plans. A design-level Geotechnical Investigation shall be prepared for the site under the direction of a California Registered Geotechnical Engineer and shall include analysis for liquefaction potential of the site soils, particularly in the perimeter dikes. Proper foundation engineering and construction shall be performed in accordance with the recommendations of the Geotechnical Investigation. The Geotechnical Investigation shall be reviewed and approved by the City’s Geotechnical Consultant and by the City Engineer. A Registered Structural Engineer shall prepare project structural design plans. Structures shall be designed to reduce the effects of anticipated seismic settlements. The Geotechnical Engineer shall review the Structural Design Plans and provide approval for the Geotechnical elements of the plans. The design plans shall identify specific mitigation measures to reduce liquefaction potential, if the potential for liquefaction is found to exist, or other ground failure modes such as lateral spreading, seismic densification or stability of the perimeter dike slopes. Mitigation measures may include ground improvement by methods such as stone columns or jet grouting. Geo-3b: Obtain a building permit. The OPSP applicant shall obtain a building permit through the City of South San Francisco Building Division. Plan Review of planned buildings and structures shall be completed by the Building Division for adherence to the seismic design criteria for planned commercial and industrial sites in the East of 101 area of the City of South San Francisco. According to the East of 101 area plan, Geotechnical Safety Element, buildings should not be subject to catastrophic collapse under foreseeable seismic events, and will allow egress of occupants in the event of damage following a strong earthquake. Less than Significant Impact Geo-4. Perimeter Dike Stability. Based on a review of available subsurface information, the dikes that surround the site are assumed to be Geo-4: Compliance with recommendations of a Geotechnical Investigation. A design-level Geotechnical Investigation shall include an Less than Significant DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 2-32 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance constructed primarily of cohesive soils derived from Bay Mud. Slope stability of the perimeter dikes is critical to the integrity of the site. Slope stability of the dikes is controlled primarily by the strength of the materials used in dike construction and of the soils on which the dikes are founded. Prior to new site development, geotechnical studies shall be undertaken to confirm the material types used in the construction of the perimeter dikes to verify that the slopes meet minimum criteria for stability under both static and seismic conditions. Failure of the perimeter dike slopes could result in settlement and differential settlement of site improvements including buildings, pavements, and utilities and pose a threat to human health. In the absence of evidence that demonstrates adequate stability of the perimeter dike slopes under both static and seismic conditions, stability of the perimeter dike slopes is considered a potentially significant impact. evaluation of static stability and seismic stability under a design magnitude earthquake event. Seismic analyses shall include pseudo-static analyses to estimate permanent slope displacements due to earthquake motions. The Geotechnical Engineer shall prepare recommendations to mitigate potential slope instability, if slope stability problems are identified. Mitigation measures may include ground improvement by methods such as stone columns or jet grouting. Design-level Geotechnical Investigations shall be completed during preliminary and final design stages and will confirm material types used in the construction of the perimeter dikes to verify that the slopes meet minimum criteria for stability under both static and seismic conditions. Knowledge of the stability of the perimeter dikes will guide the selection of any future measures to mitigate any deficiencies identified in the perimeter dike. Impact Geo-5: Variable Subsurface Conditions and Selection of Foundation Types and Depths. Geotechnical considerations for the selection of alternative foundation types for the site include the following: • The presence of Bay Mud, landfill waste and other area fill over most of the proposed building footprint areas; • Varying thicknesses of Bay Mud, landfill waste and other fill; • Sloping bedrock surface; and • Presence of possible paleochannels in the north/northwest portions of the site. These variable subsurface conditions will influence the design, performance and constructability of foundation systems for the proposed buildings and are considered a potentially significant impact. Geo-5a: Deep Foundations. Because of the magnitude of expected settlement of Bay Mud soils and waste fill materials that would occur under new building loads, the OPSP applicant must consider the use of deep foundations such as driven piles. Specific recommendations for suitable deep foundation alternatives and required penetrations will be provided during the course of a design-level geotechnical investigation and will depend on factors such as the depth and hardness of the underlying clays, sands or bedrock, and the corrosivity of the waste materials and Bay Mud soils. Suitable deep foundation types may include driven precast, prestressed concrete piles or driven closed-end steel pipe piles with the interior of the pile filled with concrete after driving. Deep foundations shall extend through all waste materials and Bay Mud and be tipped in underlying stiff to hard clays, dense sands or weathered bedrock. Where waste and Bay Mud soils underlie the site, wall and column loads as well as floor slabs shall be founded on deep foundations. Settlement of properly-designed and constructed deep foundation elements is typically less than about one-half inch. The majority of settlement typically occurs during construction as the loads are applied. Where landfill waste and Bay Mud are not present (possibly at extreme western and northwestern edges of the site) and competent soil or bedrock are present near the ground surface (within about 5 feet of finished grade elevation), shallow foundations such as footings or mats may be appropriate foundation types, as determined during the course of a design-level geotechnical investigation. Where proposed structures straddle a transition zone between these conditions, a combination of shallow Less than Significant CHAPTER 2: EXECUTIVE SUMMARY AND IMPACT OVERVIEW OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 2-33 Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance and deep foundations may be required. Any transition zones shall be identified during site- specific geotechnical investigations for preliminary and final designs. Geo-5b: Predrilling and/or Pile Configuration. Piles either shall be predrilled through the fill and landfill materials to protect the piles from damage due to unknown materials, to reduce pushing waste material deeper, and to reduce pile alignment problems or shall have a pointed tip configuration. If a drill is used, it should only loosen and break up in-place obstructions that may cause pile damage. During recent subsurface investigations reported by Treadwell & Rollo (2009b) obstructions including concrete rubble was encountered throughout the landfill area, particularly in the northern end of the site. Even with predrilling, precast concrete piles could be damaged during installation at a landfill site such as Oyster Point. For preliminary planning purposes, a precast concrete pile breakage rate during installation of 10 to 15 percent may be considered applicable. Piles usually have to include pointed tip configurations to avoid pushing landfill waste downward. These configurations are typically readily accommodated by pile driving contractors. Geo-5c: Indicator Pile Program. Prior to specifying the lengths of the production piles, drive indicator piles at the structure sites in order to observe the driving characteristic of the piles and the ability of the driving equipment when a driven pile is used. The driving criteria and pile length of production piles shall also be estimated from the information obtained from driving of the indicator piles. The contractor shall use the same equipment to drive both the indicator and production piles. Indicator pile lengths and locations shall be selected by the Geotechnical Engineer, in conjunction with the Structural Engineer and Contractor after the foundation plan has been finalized. The indicator pile program will serve to establish information on the following: • Estimates of production pile lengths; • Drivability of production piles; • Performance of pile driving equipment; and • Variation in driving resistance relative to depth and location of piles. Impact Geo-6: Drag Load on Deep Foundations. The landfill wastes and the underlying Bay Mud are settling due to consolidation and on-going decomposition-induced settlement of the wastes. Deep foundations (piles) will extend through the waste and Bay Mud layers and into underlying materials that are relatively incompressible. The Geo-6: Account for Drag Load on Deep Foundations. The Geotechnical Engineer shall account for accumulation of drag load in the structural design of the deep foundations elements (piles). Less than Significant DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 2-34 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance settlement of the waste and Bay Mud around the piles will tend to move downward relative to the pile. This settlement will accumulate a drag load on the pile element, which will depend on the material layering and thickness, pile length and load on the pile. On-going settlement of Bay Mud soils and waste materials is considered a potentially significant impact. Impact Geo-7: Landfill Gas Entry into Buildings. Construction of buildings over the landfill cap could allow landfill gas to accumulate beneath building floors and permeate into the building interiors. Landfill gas accumulation inside buildings and at the building-soil interface may adversely affect the health and safety of building occupants. Accumulation of landfill gas beneath and inside structures is a potentially significant impact. Geo-7: Incorporate Systems for Landfill Gas Control. Measures for the control of landfill gas shall be included in building design. Measures for the control of landfill gas typically include a collection system, floor slab shielding and interior alarms. Less than Significant Impact Geo-8: Landfill Waste Materials and Bay Mud. Placement of additional fill or other new loads at the site will result in additional site settlement due to consolidation settlement of the Bay Mud soils and the compaction and decomposition induced settlement of submerged waste and waste above groundwater. Due to the generally heterogeneous nature of the landfill, differential settlement of the soil cap will be on- going. This differential settlement can disrupt drainage patterns and cause damage to pavements, underground utilities and soil- supported structures. The magnitude of new settlement in response to additional fill will depend on the thickness of the fill, the lateral extent, and the current thickness of the soil cap. For estimating purposes, settlements on the order of 3 to 5 inches for every foot of new fill should be anticipated. Settlement due to the presence of unstable soil, waste and Bay Mud is a potentially significant impact. Geo-8a: Avoid Significant New Loads on Landfill Waste and Bay Mud. A design-level Geotechnical Investigation shall include exploration to more thoroughly determine the thickness and areal extent of landfill waste and Bay Mud. To avoid inducing additional settlement to the settlement that is already on-going, grading plans shall include as little additional new fill as possible, and significant new structure loads or any structures that are settlement-sensitive shall be founded on deep foundations extended below the Bay Mud, as recommended in the design-level Geotechnical Investigation report. All grading shall be planned to avoid penetrating the landfill cap and to reduce the amount of long-term settlement in response to new fills. Because the Bay Mud and waste across most of the site are still settling under the weight of existing fill and waste decomposition and will settle more under new fills, additional settlement should be expected, with the creation of localized low-lying surface areas. Existing low areas shall be corrected during site grading to allow for proper drainage. Long-term maintenance planning for the development shall also include provisions for periodic grading to correct drainage problems and improve site grades, as outlined in the Disposition and Development Agreement. The Geotechnical Engineer will recommend other site-specific recommendations based on the results of the design-level Geotechnical Investigation to mitigate on-going settlement and any additional settlement to be expected in response to new development. Geo-8b: Design Building-Soil Interface to Allow Free Movement. The Structural Engineer shall provide that structures not supported on deep foundations not be structurally tied into pile- Less than Significant CHAPTER 2: EXECUTIVE SUMMARY AND IMPACT OVERVIEW OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 2-35 Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance supported buildings, except as noted below, and shall be designed to allow free vertical movement between structures. Articulated ramps on walkways and building entrances at the interface between the pile and soil- supported areas can provide a smooth walkway over moderate differential settlements with some amount of maintenance. As the magnitude of the differential settlement increases, however, these ramps may need to be rebuilt or realigned to account for the larger elevation differential. Similar ramps may also reduce differential settlements between driveways and pile-supported parking lots. Over time, voids will tend to form beneath pile- supported buildings due to on-going settlement of the landfill. Use of wall skirts around the building perimeter will help to reduce the visual impact of these voids. Impact Geo-9: Hazardous Conditions During Excavation and Following Construction. Excavations extending into either the landfill cap or into the waste fill are expected to encounter potentially hazardous conditions including poisonous and explosive gases. This may be true in shallower excavations as well. This is a potentially significant impact during and following site construction activities. Geo-9a: Monitoring and Testing. Special precautions shall be taken to monitor the safety conditions and to provide for the safety of workers in the area. Additionally, if excavations encounter water, this water shall be tested for contaminants and may have to undergo specialized handling, treatment and/or disposal if it is contaminated. A system to disperse methane during construction shall be installed in or adjacent to the trenches. Geo-9b: Locate Underground Utilities in Soil Cap. To the extent practicable, the utilities shall be constructed in the soil landfill cap to avoid direct contact of the utility lines and construction workers with the waste material. If construction of utilities in the waste material is necessary, proper design and construction precautions shall be taken to protect the system and the workers from the corrosive and hazardous conditions of the waste. Geo-9c: Seal Trenches and Underground Structures. Trenches and underground structures shall be sealed to preclude gas intrusion. Typical types of sealing procedures include providing a low permeability clay cover of 1 foot over the top of the pipe, or the utility trench be lined with a relatively impervious geomembrane. Underground manholes may be shielded from methane intrusion by placement of a membrane around the outside of the structure. To reduce gas migration off-site within the utility trenches, all trenches crossing the transition zone between the landfill and non-landfill portions of the property shall be sealed with a clay plug surrounding the pipe or other approved methods. In addition, plugs shall also be provided at the perimeters of buildings to reduce migration of gas through the utility trenches to beneath the buildings. Less than Significant DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 2-36 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance Impact Geo-10: Damage to Landfill Cap Due to Excavation. Excavations for buildings, utilities and other underground structures that extend into the landfill cap may result in damage to the landfill cap. This would be a potentially significant impact on safety during and after construction and on the continued performance of the landfill cap. Geo-10: Provide For Continuity of Landfill Cap. Following planned landfill excavation and landfill cap repair, the project Civil Engineer shall require that excavations for building foundations, utility trenches and other underground structures be configured to maintain continuity of the landfill cap. The specific configuration will depend upon the excavation depth and orientation to underlying wastes. However, a low-permeability layer of soil or a geomembrane properly tied to surrounding cap areas may be required. Less than Significant Impact Geo-11: Stresses at Building Connections. Underground utilities will be subject to distress at building connection locations due to differential settlement. It is anticipated that the most crucial sections of the utility lines will occur at the interface between the soil supported utility line and the pile supported buildings. At this interface differential settlements of several feet are possible. This would be a potentially significant impact on the performance of underground utilities. Geo-11: Common Trenches and Vaults. Where underground utilities are to be located in landfill areas, consideration shall be given to reducing the number of utilities trenches by locating utilities in common trenches to the extent practicable. In addition, vaulted systems shall be designed and maintained at such interfaces that provide flexible and/or expandable connections to the proposed buildings. In addition, the utility lines beneath buildings shall be suspended from hangers fastened to structural floor slabs. Less than Significant Impact Geo-12: Stresses in Utility Line Materials. Differential settlement will cause distress to the materials used in underground utilities construction. On a landfill site the effects of differential settlement are typically more severe than at a conventional site due to the generally higher levels of settlement that occur. Differential settlement is a potentially significant impact on the performance of underground utilities. Geo-12: Flexible Materials and Joints. Utility lines shall be constructed of flexible pipe such as welded polyethylene to accommodate differential settlement within the waste material and landfill cap. At the border of the landfill, where differential settlements are expected to be large, the utility lines shall be designed to allow for rotation. As with buried utilities on a conventional site, proper bedding and backfilling shall be completed, as specified in a design-level geotechnical investigation report. Less than Significant Impact Geo-13: Disruption of Flow Gradient. Differential settlement will tend to disrupt flow gradients in gravity-flow sewers and storm drains. This is a potentially significant impact on the performance of these utilities. Geo-13: Increase Flow Gradient. The Civil Engineer shall consider increasing the flow gradient in sewers and storm drains so that differential settlements will not disrupt the flow. An alternative is to provide a pumping system that does not rely on gravity flow. Such measures will reduce the impact of reduced flow gradient due to differential settlement to less than significant. This applies to the entire OPSP, including the Phase I Project. Less than Significant Impact Haz-1: Routine transportation, use or disposal of hazardous materials. While specific tenants have not yet been identified, research laboratories are likely to handle materials considered to be biological hazards, chemical hazards and/or carry a risk of fire or explosion. The risk of accidental upset and environmental contamination from routine transport, storage, use and disposal of hazardous and potentially hazardous materials to the public and environment is a potentially significant impact. Haz-1a: Plan Review for Adherence to Fire and Safety Codes. Building space shall be designed to handle the intended use, with sprinklers, alarms, vents, and secondary containment structures, where applicable. These systems shall pass plan review through the City of South San Francisco Planning, Building and Fire Departments. Haz-1b: Construction Inspection and Final Inspection Prior to Occupancy. During construction, the utilities including sprinkler systems shall pass pressure and flush tests to make sure they perform as designed. At the end of construction, occupancy shall not be allowed until a final inspection is made Less than Significant CHAPTER 2: EXECUTIVE SUMMARY AND IMPACT OVERVIEW OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 2-37 Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance by the Fire Department for conformance of all building systems with the Fire Code and National Fire Protection Agency Requirements. The inspection shall include testing of sprinklers systems, alarm systems, ventilation and airflow systems, and secondary containment systems. The inspection shall include a review of the emergency evacuation plans. These plans shall be modified as deemed necessary. Haz-1c: Hazardous Materials Business Plan Program. Businesses occupying the development shall complete a Hazardous Materials Business Plan for the safe storage and use of chemicals. The Business Plan shall include the type and quantity of hazardous materials, a site map showing storage locations of hazardous materials and where they may be used and transported from, risks of using these materials, material safety data sheets for each material, a spill prevention plan, an emergency response plan, employee training consistent with OSHA guidelines, and emergency contact information. Businesses qualify for the program if they store a hazardous material equal to or greater than the minimum reportable quantities. These quantities are 55 gallons for liquids, 500 pounds for solids and 200 cubic feet (at standard temperature and pressure) for compressed gases. Exemptions include businesses selling only pre- packaged consumer goods; medical professionals who store oxygen, nitrogen, and/or nitrous oxide in quantities not more than 1,000 cubic feet for each material, and who store or use no other hazardous materials; or facilities that store no more than 55 gallons of a specific type of lubricating oil, and for which the total quantity of lubricating oil not exceed 275 gallons for all types of lubricating oil. These exemptions are not expected to apply to on-site laboratory facilities. Businesses occupying and/or operating at the proposed development shall submit a business plan prior to the start of operations, and shall review and update the entire Business Plan at least once every two years, or within 30 days of any significant change, including without limitation, changes to emergency contact information, major increases or decreases in hazardous materials storage and/or changes in location of hazardous materials. Plans shall be submitted to the San Mateo County Environmental Health Department (SMCEHD) Business Plan Program, which may be contacted at (650) 363-4305 for more information. The SMCEHD shall inspect the business at least once a year to make sure that the Business Plan is complete and accurate. Haz-1d: Hazardous Waste Generator Program. Qualifying businesses shall register and comply DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 2-38 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance with the hazardous waste generator program. The State of California DTSC authorized the SMCEHD to inspect and regulate non-permitted hazardous waste generators in San Mateo County based on the Hazardous Waste Control Law found in the California Health and Safety Code Division 20, Chapter 6.5 and regulations found in the CCR Title 22, Division 4.5. Regulations require businesses generating any amount of hazardous waste as defined by regulation to properly store, manage and dispose of such waste. SMCEHD staff also conducts surveillance and enforcement activities in conjunction with the County District Attorney's Office for businesses or individuals that significantly violate the above referenced law and regulations. Haz-1e: Compliance with Applicable Laws and Regulations. All transportation of hazardous materials and hazardous waste to and from the OPSP area shall be in accordance with CFR Title 49, US Department of Transportation (DOT), State of California Department of Transportation (Caltrans), and local laws, ordinances and procedures including placards, signs and other identifying information. Impact Haz-2: Accidental Hazardous Materials Release During Disturbance of Landfill Materials. Site preparation and construction activities in the vicinity of the landfill could result in release of hazardous solid waste, groundwater and/or soil vapor and the potential for direct exposure to workers engaged in soil excavation and dewatering activities. This represents a potentially significant impact. Haz-2: Waste Excavation and Re- disposition. A plan shall be written for management of excavated wastes/refuse. Non-hazardous excavated waste shall be re-deposited in an alternate part of the site and any hazardous waste shall be relocated off-site for appropriate disposal. The plan can be a section of the Site Management Plan (Mitigation Measure Haz-4a), or a stand alone document. The plan shall include measures to avoid releases of wastes or waste water into the environment and to protect workers and the public. The details of the plan shall be based, in part, on the amount of material to be removed and the final design of foundation structures, but will generally include the following, as deemed appropriate by the regulatory agencies, particularly DTSC and RWQCB: • To the greatest extent possible, use existing boring data to obtain pre-characterization of refuse for off-site disposal, and to pre-plan areas to be removed versus areas to be re-deposited on-site. • Divide excavation areas into daily sections; plan to complete excavation and backfilling a section during each working day. Minimize the time period that refuse is exposed. • Review existing boring data and existing site documentation to evaluate potential subsurface materials to be encountered. • Stake out area to be excavated. • If excavation is to be conducted at depths where Less than Significant CHAPTER 2: EXECUTIVE SUMMARY AND IMPACT OVERVIEW OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 2-39 Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance groundwater is to be encountered, conduct dewatering to minimize worker potential direct contact with groundwater. Removed groundwater shall be treated in accordance with the requirements outlined in the Site Management Plan (Mitigation Measure Haz-4a). • Screen excavation site with a portable photoionization detector and combustible gas monitor for landfill gasses. Continue screening progress of each excavation section as work proceeds. Use foam suppressants or 6 inches minimum of daily soil cover for nuisance odors. • Provide carbon dioxide gas source (fire extinguisher or cylinder) to flood excavation as necessary to prevent migration of gases into atmosphere above excavation, minimize explosive or fire potential, and control nuisance and odors. • Begin excavation and segregate soil and /or clay cap material above refuse for reuse as foundation layer. • Upon reaching refuse, place refuse into dump truck standing by on-site. • Dispose of each truck load of refuse immediately after filling equipment. All loads to be covered when hauling. Refuse shall be either re-deposited on-site in a specified area, or hauled to an off-site disposal facility. • Prior to relocation, field verify each load for disposal classification type (landfill classification, Class 3 or Class 2). If waste for off-site disposal is characterized as either California or Federal Hazardous Waste as defined in the criteria described in CCR Title 22 Section 66261, then the hazardous waste shall be tracked using the Uniform Hazardous Waste Manifest System (USEPA Form 8700-22). • Hazardous and if necessary, non-hazardous waste shall be transported to the appropriate disposal facility using a permitted, licensed, and insured transportation company. Transporters of hazardous waste shall meet the requirements of 40 CFR 263 and 22 CCR 66263. Copies of uniform hazardous waste manifests signed by the designated waste disposal facility shall be retained for at least five years from the date the waste was accepted by the initial transporter. Copies of records pertaining to the characterization of hazardous or nonhazardous waste shall be retained for a minimum of three years. • Upon reaching over-excavation depth, place a minimum of 6-inch thick layer of appropriate backfill soil on excavation bottom to seal exposed refuse surface. Place soil by the end of the same day excavation is completed. • Upon completion of excavation, begin cap DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 2-40 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance placement procedures. Specific measures shall be targeted to minimize the duration of waste exposure, plan for appropriate final destination of wastes based on the presence of contaminants of concern, allow for adjustment in plan based on unexpected occurrences, and to protect worker safety and the public. Additional work plan measures are discussed in Haz-4a. In addition, worker protection measures for soil and dewatering are discussed in Haz-6a. Measures specific to off-site air quality during construction are included in mitigation measure Air-4. Impact Haz-3: Accidental Release of Hazardous Building Materials. During demolition of existing buildings, hazardous building materials could be released from structures at the site. These represent potentially significant impacts. Haz-3: Demolition Plan and Permitting. A demolition plan with permit applications shall be submitted to the City of South San Francisco Building Department for approval prior to demolition. Prior to obtaining a demolition permit from the Bay Area Air Quality Management District (BAAQMD), an asbestos demolition survey shall be conducted in accordance with the requirements of BAAQMD Regulation 11, Rule 2. Prior to building demolition, hazardous building materials such as peeling, chipping and friable lead-based paint and asbestos containing building materials, if identified on the site, shall be removed in accordance with all applicable guidelines, laws, and ordinances. The Demolition Plan for safe demolition of existing structures shall incorporate recommendations from the site surveys for the presence of potentially hazardous building materials, as well as additional surveys if required by the City. The demolition plan shall address both on-site Worker Protection and off-site resident protection from both chemical and physical hazards. Contaminated building materials, if identified, shall be tested for contaminant concentrations and shall be disposed of to appropriate licensed landfill facilities. The Demolition Plan shall include a program of air monitoring for dust particulates and attached contaminants, as merited by the surveys. The need for dust control and suspension of work during dry windy days shall be addressed in the plan. Less than Significant Impact Haz-4: Accidental Future Hazardous Materials Release of Pre-existing Site Materials. Landfill materials, which include hazardous materials in solid waste, groundwater and soil vapor, shall remain on-site following construction. Installation of new structures presents the potential for build up of soil gasses within the structures, posing a risk to building occupants and additional loading of the site surface could increase the rate of on-site waste settlement, leading to off-site migration of leachate. This represents a potentially significant impact. Haz-4a: Landfill Cap Upgrades. A landfill cap currently exists to prevent exposure of the public to impacted solids or groundwater. The cap shall be repaired and upgraded to meet CCR Title 27 requirements. CCR Title 27 requires closed landfills have a minimum 4 foot cap, consisting of a 2 foot base layer, a 1 foot clay layer with specified low hydraulic conductivity and a 1 foot erosion control layer. The minimum 4 feet of clean material that comprises the cap shall prevent exposure of the underlying material, preventing releases at the surface. The low hydraulic conductivity layer shall also act to minimize generation of leachate. Haz-4b: Use Of Deep Foundations To Prevent Load Induced Settlement. Buildings on fill Less than Significant CHAPTER 2: EXECUTIVE SUMMARY AND IMPACT OVERVIEW OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 2-41 Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance shall be supported using driven steel or concrete piles founded in stiff to hard clays, dense sands or weathered bedrock underlying the fill. Both the structural loads and building floor slabs shall be supported on piles. This will avoid placing additional building loads on fill material. Haz-4c: Minimization of Irrigation Water Use. Landscaping of the site shall be selected to stabilize the soil, prevent erosion, and reduce the need for extensive irrigation. Excessive water could infiltrate the landfill cap and produce leachate. To prevent this, low-water vegetation shall be selected to reduce irrigation water. In addition the thickness of the erosion resistant layer in landscaped areas will be increased to minimize intrusion of roots into the lower layers of the cover. Haz-4d: Monitoring for Leachate Migration. A series of natural and man-made barriers have been implemented to prevent migration of impacted leachate into the surrounding area. Based on monitoring at the site implemented per the PCMP, these measures are currently effective in preventing releases. Leachate shall continue to be monitored, as discussed in Haz-4e, below. Leachate containment for the landfill portion of the OPSP shall be upgraded as needed during and following construction, as per the requirements of RWQCB Order No. 00-046 and the PCMP. Haz-4e: Operation and Maintenance Activities. Operation and maintenance (O&M) activities are expected to occur indefinitely at the site. Operation and maintenance activities shall include inspections and observations of site features to protect the landfill cap, prevent utility damage, maintain gravity flow of sewer systems, maintain the landfill gas barrier and venting systems, and monitor for leachate and groundwater contaminant concentrations. O&M shall act to prevent releases of hazardous materials by identifying deficits in engineering controls prior to release events. Impact Haz-5: Accidental Hazardous Materials Release of Laboratory Chemicals. Following construction, operations at the proposed facilities are expected to represent a continuing threat to the environment through accidental release of hazardous materials since the site is proposed to include laboratory facilities, where hazardous materials stored or used on site could lead to an accidental release. This represents a potentially significant impact. Haz-5: California Accidental Release Prevention Program (CalARP). Future businesses at the development shall check the state and federal lists of regulated substances available from the SMCEHD. Chemicals on the list are chemicals that pose a major threat to public health and safety or the environment because they are highly toxic, flammable or explosive. Businesses shall determine which list to use in consultation with the SMCEHD. Should businesses qualify for the program, they shall complete a CalARP registration form and submit it to SMCEHD. Following registration, they shall submit a Risk Management Plan (RMP). RMPs are designed to handle accidental releases and ensure that businesses have the proper information to provide to emergency response teams Less than Significant DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 2-42 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance if an accidental release occurs. All businesses that store or handle more than a threshold quantity (TQ) of a regulated substance shall develop a RMP and follow it. Risk Management Plans describe impacts to public health and the environment if a regulated substance is released near schools, residential areas, hospitals and childcare facilities. RMPs shall include procedures for keeping employees and customers safe, the handling regulated substances, staff training, equipment maintenance, checking that substances are stored safely, and responding to an accidental release. Impact Haz-6: Exposure to Contaminated Soil, Soil Vapor, and Groundwater. As currently designed, utilities and foundation slabs shall be separated from landfill wastes by a minimum of 4 feet of clean material, however the potential for future maintenance work to penetrate into the subsurface where contamination remains cannot entirely be discounted. Soil and groundwater disturbance presents an exposure hazard to workers and trespassers. Disturbance of the subsurface also increases the potential for contamination to spread through surface water runoff, and through wind blown dust. These impacts are potentially significant. Haz-6a: Development and Implementation of Site Management Plans. A Site Management Plan shall be prepared that addresses the exposure risk to people and the environment resulting from future demolition, construction, occupancy, and maintenance activities on the property. The plans for the landfill portion of the OPSP shall be in accordance with RWQCB order No. 00-046, the PCMP and recommendations of the Environmental Consultant, and shall be reviewed and approved by the RWQCB, DTSC, the SMCEHD Groundwater Protection Program and the City of South San Francisco Public Works Department. Specific mitigation measures designed to protect human health and the environment shall be provided in the plan. At a minimum, the plan shall include the following: 1) Requirements for site specific Health and Safety Plans (HASP) shall be prepared in accordance with OSHA regulations by all contractors at the OPSP area. This includes a HASP for all demolition, grading and excavation on the site, as well as for future subsurface maintenance work. The HASP shall include appropriate training, any required personal protective equipment, and monitoring of contaminants to determine exposure. The HASP shall be reviewed and approved by a Certified Industrial Hygienist. The plan shall also designate provisions to limit worker entry and exposure and shall show locations and type of protective fencing to prevent public exposure to hazards during demolition, site grading, and construction activities. 2) Requirements for site-specific construction techniques that would minimize exposure to any subsurface contamination shall be developed. This shall include dewatering techniques to minimize direct exposure to groundwater during construction activities, treatment and disposal measures for any contaminated groundwater removed from excavations, trenches, and dewatering systems in accordance with local and Less than Significant CHAPTER 2: EXECUTIVE SUMMARY AND IMPACT OVERVIEW OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 2-43 Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance Regional Water Quality Control Board guidelines. Groundwater encountered in excavations shall not be discharged into the neighboring storm drain, but into a closed containment facility, unless proven to have concentrations of contaminants below established regulatory guidelines. Extracted contaminated groundwater shall be required to be stored in tanks or other sealed container until tested. If testing determines that the water can be discharged into the sanitary sewer system, then the applicant shall acquire a ground water discharge permit from the City of South San Francisco Sanitary Sewer District and meet local discharge limits before being allowed to discharge into the sanitary sewer. Water shall be analyzed for the chemicals of concern at the site, including benzene, ethylbenzene, xylenes, chlorobenzene, naphthalene and additional compounds as requested by the receiving facility or the City of South San Francisco. 3) Waste relocation. Relocation or removal of existing landfill waste/refuse will be required for landfill cap upgrades and for site construction. Excavated waste can either be re-deposited on site or disposed of at an active landfill facility. Off-site disposal will require pre-characterization of the waste for acceptance at an approved waste disposal facility. Waste manifests will be prepared to document transportation and disposal. On-site disposal shall require proper placement, compaction, and capping of the refuse material. In either case, segregation of Class 2 and Class 3 from Class 1 material for disposal purposes shall be performed on-site to the extent possible. No Class 1 material shall be relocated or re-deposited on-site. BAAQMD Regulation 8 Rule 34 section 118 documents a limited exemption for construction activities at landfill sites. This section specifies that when the construction activities are related to “installing, expanding, replacing, or repairing components of the landfill gas, leachate, or gas condensate collection and removal systems.” Excavation for cap upgrades falls under this exemption. Excavation for construction purposes will also likely fall under this exemption. As such it will be necessary to provide BAAQMD with construction plans and other documentation as detailed under this regulation for the purposes of obtaining a letter of exemption from BAAQMD. Excavation procedures are also discussed in Measure Haz-2. 4) Future subsurface work plan. The plan shall document procedures for future subsurface landscaping work, utility maintenance, etc., with proper notification, where applicable. The plan shall include a general health and safety plan for DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 2-44 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance each expected type of work, with appropriate personal protective equipment, where applicable. This plan may be included in the operations and maintenance plan as appropriate. Haz-6b: Landfill Gas System. Section 21160 of Title 27 of the CCR requires that closed landfills implement and maintain landfill gas control. A landfill gas (LFG) venting system shall be placed under the bottom slabs of each structure built entirely or partially over landfill material, to collect and vent the build up of gases diffusing through the landfill cap. The LFG system shall include spray- applied vapor barrier membranes, horizontal collection and passive venting, gas detection and monitoring. The system shall either have backup active collection and venting or shall be designed to facilitate retrofitting with an active system, if measures warrant the retrofit. Potential migration of LFG into the building space shall be mitigated by the collection and venting system, and secondly by the spray-applied membrane. Subsurface landfill gases shall be vented by a network of perforated piping placed beneath the building slabs. The exhaust gases shall be manifolded to a series of riser piping that is to be vented above structure roofs. Passive landfill gas systems do not require permits, however if an active system is installed, either at the time of construction or as part of a retrofit, a BAAQMD permit will be needed. Haz-6c: Non-use of Groundwater. Water supply wells shall not be installed at the site. This will prevent direct contact between the public and site groundwater and leachate. Haz-6d: San Mateo County Environmental Health Department Closure of Existing Facilities. Any businesses on the site that are currently registered in the hazardous materials business plan program shall submit a closure work plan in accordance with the SMCEHD Business Closure Policy prior to vacating the property. The closure plan shall detail any necessary sampling and remediation. Closure shall not be granted until businesses have demonstrated there is no need for further remediation, and shall include documentation of the removal of any hazardous chemicals. Impact Hydro-1: Potential Contamination of Off-Site Waters due to Leachate Migration. The OPSP area is located within the historical limits of the Bay. Subsurface water at the site is underlain by Bay Mud and has a low-hydraulic conductivity cap, which confines the groundwater. Based on ongoing monitoring at the site, leachate, which has elevated contaminant concentrations from the landfill material, is not migrating off-site. Re-development of the site shall require excavation of a portion of the Hydro-1: Best Management Practices (BMPs) shall be used during installation of foundation piers to reduce the potential for gaps in the subsurface confining layers around the piers. BMP requirements shall be identified in the SWPPP and shall be developed by the applicant or their authorized representative. The exact BMPs to be implemented shall depend on final pier design and type, but can include pre-drilling and grouting of concrete piers, use of hollow steel piers, or other methods to reduce the risk of displaced refuse Less than Significant CHAPTER 2: EXECUTIVE SUMMARY AND IMPACT OVERVIEW OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 2-45 Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance landfill cap, and shall require deep foundation piers which may penetrate the Bay Mud. The potential for off-site migration of leachate as a result of modification the landfill cap and underlying Bay Mud represents a potentially significant impact. creating a void in the Bay Mud layer. The proposed BMPs shall be benchmarked against the California Department of Transportation Stormwater Quality Handbooks Construction Site Best Management Practices (BMPs) Manual (2003 and associated updates). Mitigation Measure Haz-4a: Landfill Cap Upgrades would also reduce impact Hydro-1 through repair and upgrade of the cap which will act to minimize generation of leachate. Mitigation Measure Haz-4d and 4e: Monitoring for Leachate Migration and Operation and Maintenance Activities would also reduce impact Hydro-1 through requirements for post-construction monitoring for leachate migration, with repairs to prevent migration completed on an as needed basis. Impact Hydro-2: Potential Construction and Post-construction Contamination of Bay Waters: Construction activities at the site will create temporary and long term alterations of the site terrain, creating potential erosion concerns. The migration of laboratory and parking lot pollutants into the bay could potentially impair water quality. This represents a potentially significant impact. Hydro-2: Preparation and Implementation of Project SWPPP. Pursuant to NPDES requirements, the applicant of a project under the OPSP shall develop a SWPPP to protect water quality during construction. If the SWPP will be developed after September 2, 2011, the SWPPP shall be developed by a California Qualified SWPPP Developer in accordance with the State Water Resources Control Board Construction General Permit 2009-009- DWQ. The project SWPPP shall include, but is not limited, to the following mitigation measures for the construction period: 1) Grading and earthwork shall be allowed with the appropriate SWPPP measures during the wet season (October 1 through April 30) and such work shall be stopped before pending storm events. 2) Erosion control/soil stabilization techniques such as straw mulching, erosion control blankets, erosion control matting, and hydro-seeding, shall be utilized in accordance with the regulations outlined in the Association of Bay Area Governments “Erosion & Sediment Control Measures” manual. Silt fences shall be installed down slope of all graded slopes. Hay bales shall be installed in the flow path of graded areas receiving concentrated flows and around storm drain inlets. 3) BMPs to be developed by the applicant shall be used for preventing the discharge or other construction-related NPDES pollutants beside sediment (i.e. paint, concrete, etc) to downstream waters. 4) After construction is completed, all drainage facilities shall be inspected for accumulated sediment and these drainage structures shall be cleared of debris and sediment. In accordance with the handbook C.3 Stormwater Technical Guidance, Version 2, permanent mitigation measures for stormwater Less than Significant DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 2-46 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance shall be submitted as part of project application submittals with the Planning Permit Application and the Building Permit Application. Elements that shall be addressed in the submittals include the following: 5) Description of potential sources of erosion and sediment at the OPSP area. R&D activities and significant materials and chemicals that could be used at the proposed OPSP area shall be described. This shall include a thorough assessment of existing and potential pollutant sources. 6) Identification of BMPs to be implemented at the OPSP area based on identified industrial activities and potential pollutant sources. Emphasis shall be placed on source control BMPs, with treatment controls used as needed. 7) Development of a monitoring and implementation plan. Maintenance requirements and frequency shall be carefully described including vector control, clearing of clogged or obstructed inlet or outlet structures, vegetation/landscape maintenance, replacement of media filters, etc. 8) The monitoring and maintenance program shall be conducted as described in Haz-4e. 9) Proposed pervious and impervious surfaces, including site design measures to minimize impervious surfaces and promote infiltration (except where the landfill cover is present). 10) Proposed locations and approximate sizes of stormwater treatment measures. Impact Hydro-3: Erosion or Siltation On- or Off-Site. Construction of the proposed OPSP would involve demolition of existing structural foundations and will involve excavation of both landfill waste material and the earthen cap overlying the waste. Construction operations associated with the OPSP would present a threat of soil erosion from soil disturbance by subjecting unprotected bare soil areas to the erosional forces of runoff during construction activities. This represents a potentially significant impact. Hydro-3: Compliance with NPDES Requirements. Applicants for a project under the OPSP shall comply with all Phase I NPDES General Construction Activities permit requirements established by the CWA and the Grading Permit requirements of the City of South San Francisco. Erosion control measures to be implemented during construction shall be included in the project SWPPP. The project SWPPP shall accompany the NOI filing and shall outline erosion control and storm water quality management measures to be implemented during and following construction. The SWPPP shall also provide the schedule for monitoring performance. Refer to Mitigation Measure Hydro-2 for more information regarding the project SWPPP. Implementation of Phase I NPDES General Construction Activities permit requirements would reduce construction-related impacts associated with erosion and/or siltation to less-than-significant. Less than Significant Impact Traf-1: Trip Generation Exceeds 100 Trips During Peak Hours. Both the Phase I Project and the entire OPSP would generate more than 100 net new two-way trips during the AM Traf-1: Transportation Demand Management Program. The OPSP sponsors shall implement a Transportation Demand Management (TDM) program consistent with the City of South San Less than Significant CHAPTER 2: EXECUTIVE SUMMARY AND IMPACT OVERVIEW OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 2-47 Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance and PM peak hours (1,402 trips during the AM peak hour and 1,621 trips during the PM peak hour at build out of the OPSP, as shown in Table 16.19). The San Mateo City/County Association of Governments (C/CAG) Agency Guidelines for the implementation of the 2003 Draft Congestion Management Program (“C/CAG Guidelines”) specifies that local jurisdictions must ensure that the developer and/or tenants will mitigate all new peak hour trips (including the first 100 trips) projected to be generated by the development. This would be a significant impact. Francisco Zoning Ordinance Chapter 20.400 Transportation Demand Management, and acceptable to C/CAG. These programs, once implemented, must be ongoing for the occupied life of the development. The C/CAG guidelines specify the number of trips that may be credited for each TDM measure. Impact Traf-2: Pedestrian Walkways. Sidewalks will be provided along both sides of Oyster Point Boulevard and Marina Boulevard internal to the OPSP site. Sidewalks will also be provided along both sides of all other internal roadways connecting to Marina Boulevard. The Phase I TDM Conceptual Site Plan (June 1, 2010) shows pedestrian connections between OPSP buildings and the sidewalks lining Oyster Point Boulevard and Marina Boulevard. No such detail has been provided by the applicant for the other phases of development. No detail has been provided regarding pedestrian access to the Phases III & IV garage and whether pedestrian access points are proposed that could encourage midblock crossing. These would be potentially significant impacts. Traf-2: Pedestrian Facilities. To discourage mid-block crossing, pedestrian flow across Oyster Point Boulevard between the Phase III & IV garage and the Phase III & IV offices shall be regulated to the following extent. Pedestrian access shall only be allowed at the north and south ends of the garage, adjacent to signalized or all-way stop intersections. Less than Significant Impact Traf-5: Year 2035 Internal Circulation. Year 2035 Base Case + OPSP AM and PM peak hour volumes expected internal to the OPSP site along Oyster Point Boulevard and Marina Boulevard (with full OPSP development) are presented in Appendix E, Figure 21, while projected roadway geometrics and control are presented in Appendix E Figure 22. Operations analysis has been conducted for the Oyster Point Boulevard / Marina Boulevard, Marina Boulevard / Phase I access / Bayfront parking lot, Oyster Point Boulevard / Phase II garage / Phases III / IV garage and Oyster Point Boulevard / North Access intersections. The north intersection includes an easterly extension of Oyster Point Boulevard to serve a secondary access to the OPSP Phases III / IV garage as well as traffic from two existing office buildings to the east of the OPSP. The western leg of the north access intersection will provide access to the Oyster Cove Marina to the west of the OPSP. Based upon an iterative analysis process, it was determined that all-way stop control would only provide acceptable operation at the Marina Boulevard / Phase I and Oyster Point Boulevard / North Access intersections. Signalization would be required at the other two locations. At City Traf-5: Internal Circulation System Signalization. The OPSP applicant shall provide signals at the Oyster Point Boulevard / Marina Boulevard and Oyster Point Boulevard / Phase II Access / Phases III / IV garage access intersections when volumes are approaching warrant criteria levels.

As shown, all internal intersections should function at acceptable AM and PM peak hour levels of service with the assumed geometrics and signal / all-way stop control with either Phases III / IV garage access Option 1 or 2. Failure of the applicant to provide required signalization would result in less than acceptable operation. This would be a significant impact. Impact Traf-6: Intersection Level of Service. The following intersection would receive a significant impact due to the addition of Phase I Project traffic to year 2015 Base Case volumes (see Table 16.11). • Oyster Point Boulevard / Gateway Boulevard / U.S.101 Southbound Flyover Off-Ramp AM Peak Hour: The Phase I Project would increase volumes by 9.11 percent at a location with unacceptable LOS F Base Case operation. PM Peak Hour: The Phase I Project would degrade acceptable Base Case LOS D operation to unacceptable LOS E operation. This would be a significant impact. Traf-6: Oyster Point Boulevard / Gateway Boulevard / U.S.101 Southbound Flyover Off-Ramp (see Table 16.23 and Figure 23 in Appendix E) The following improvements would mitigate the Phase I Project-specific impacts. All of these improvements (other than measures to the Southbound Flyover Off-Ramp, the eastbound departure and the southbound approach) are included as part of the East of 101 Transportation Improvement Program (TIP) and will be funded via the Phase I Project’s traffic impact fee contribution to this program. The Phase I Project shall also provide a fair share contribution towards all measures currently not part of the TIP. Adjust signal timing. Provide an additional through lane on the Oyster Point westbound approach (extending from Veterans Boulevard) and continue to the Dubuque/U.S.101 Northbound On-Ramp intersection. Restripe the Oyster Point Boulevard eastbound approach from a left, 2 throughs and a combined through/right turn lane to a left, 2 throughs and an exclusive right turn lane. Restripe the Southbound Flyover Off-Ramp approach from 2 through lanes and an exclusive right turn lane to two through lanes and a combined through/right turn lane. In conjunction with this measure, add a third eastbound departure lane on Oyster Point Boulevard (not part of TIP). Add a second exclusive right turn lane on the southbound Genentech property driveway approach (not part of TIP).

Less than Significant Impact Util-2: Exceed Existing Pump Station and Subtrunk Wastewater Capacity. The additional wastewater flows from the construction of the total OPSP will exceed the hydraulic capacities of the existing Oyster Point Subtrunk, and Pump Station No. 2. The inadequate capacity to serve the project’s projected demand of the wastewater subtrunk and pump station is a potentially significant impact. Util-2a: Upsize Pump Station No. 2. To provide the required sewer capacity for the Plan, Pump Station No. 2 will need to be upsized to a firm capacity of 1.6. The Sewer Master Plan includes expanding Pump Station No. 2. Improvements under the Sewer Master Plan are funded through a flat-rate sewer connection fee for new development and a monthly impact fee. The amount of the impact fee is based on the quantity (flow) of wastewater generated. The occupants of the proposed OPSP development shall pay the sanitary sewer fees imposed by the City of South San Francisco in order to mitigate the cost of the pump station upgrade necessary to manage the wastewater flows generated by the OPSP. Util-2b: Oyster Point Subtrunk Replacement. To provide the required sewer capacity, the Oyster Point Subtrunk will need to be replaced with a larger sized trunk line, with sizes ranging from 12, 15, and 18-inches. The majority of these improvements are included in Less than Significant CHAPTER 2: EXECUTIVE SUMMARY AND IMPACT OVERVIEW OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 2-55 Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance the Sewer Master Plan and are funded through a flat-rate sewer connection fee for new development and a monthly impact fee.

An additional 700 feet of 8-inch diameter sewer trunk from Eccles Avenue to Gull Road needs to be upsized to a 12-inch diameter trunk sewer. This segment of sewer trunk was not included in the recommendations in the Sewer Master Plan. The applicants shall either work with the City to include this improvement in an Sewer Master Plan update or directly fund their fair share of the improvement. Less than Significant Impacts Impact Vis-1: Scenic Vista. Many prominent visual landmarks, such as the San Bruno Mountains, the San Francisco Bay, Sign Hill, and Wind Harp, are visible from properties in the East of 101 Area in South San Francisco, including along the Bay Trail. CEQA generally protects against significant adverse impacts to public views of such scenic vistas, taking into consideration the environmental context i.e., whether the view is from a recreation area or scenic expanse, as opposed from a developed urban area. Here, the Project will not significantly impact public views of a scenic vista from a recreation area or scenic expanse. Further, given the OPSP’s urban setting, a less-than- significant impact would result on scenic vistas with no mitigation warranted. No mitigation warranted. Less than Significant Impact Air-3: Possible Exposure of Sensitive Receptors to Operational Odors. Development anticipated under the OPSP may expose sensitive receptors to odors through development of new non-residential development that may be sources of odors near sensitive receptors. Such exposure would represent a less-than-significant impact. No mitigation warranted. Less than Significant Impact Bio-1: Loss of Common Terrestrial Habitats. Development of the OPSP would result in the modification or loss of Developed and Landscaped areas, California Annual Grassland/Coyote Brush Scrub, Ornamental Woodland Habitats and Non-Jurisdictional Armored Rock Levee Slope Habitats. However, none of these habitats represent particularly sensitive, valuable (from the perspective of providing important wildlife habitat), or exemplary occurrences of these habitat types. No mitigation warranted. Less than Significant DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 2-56 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance Therefore, impacts to these habitats, and the loss of potential nesting, roosting, and foraging opportunities associated with such habitats, are considered a less-than-significant impact. Impact Bio-5: Loss of Habitat for Non-breeding Special-Status Wildlife Species. Several terrestrial special-status species may use the OPSP area as transients or migrants, or may occur in very low numbers, but are not expected to breed at the site or to be present in any numbers. These species include the American peregrine falcon, black skimmer, harlequin duck, northern harrier, Vaux’s swift, yellow warbler, tricolored blackbird, white-tailed kite and loggerhead shrike. There would be no substantial loss of foraging or non-breeding habitat for any of these species, as the OPSP footprint primarily includes already developed and/or heavily impacted areas. Therefore, the impact on non- Breeding Special-Status Wildlife Species would be less-than-significant. No mitigation warranted. Less than Significant Impact Bio-8: Increased Recreational Disturbance on Wildlife. Recreational demand in the Oyster Point area is expected to increase with the development of the OPSP and such increased use could potentially subject biological resources (both within and outside the OPSP area, such as waterbirds using the edge of San Francisco Bay) to greater disturbance by people walking and biking. However, because there is already a substantial amount of human activity at Oyster Point, the area is already largely habituated to high levels of human activity. Increased use of trails or other areas that are already fairly heavily used by people is thus not expected to reduce the use of such areas by wildlife. Therefore, an increase in recreational users of the Bay Trail and other areas adjacent to wildlife habitat resulting from construction of the OPSP would have a less-than-significant impact on wildlife in these areas. No mitigation warranted. Less than Significant Impact Bio-9: Increased Lighting Impacts on Wildlife. Lighting in and adjacent to more natural areas on the OPSP area, especially the shoreline along San Francisco Bay, is expected to increase as a result of the OPSP. Artificial lighting has been demonstrated to cause changes in the physiology and behavior of certain animals. However, the OPSP area is already subjected to substantial amounts of artificial night lighting, including night lighting from roads, parking lots, and buildings. As a result, any wildlife currently using the site is habituated to the lighting present within this urban area. The OPSP incorporates guidelines for the design of lighting to minimize light pollution in areas other than those intended No mitigation warranted. Less than Significant CHAPTER 2: EXECUTIVE SUMMARY AND IMPACT OVERVIEW OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 2-57 Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance to be lit. Therefore, impacts from increased lighting levels on wildlife will be less-than- significant. Impact Bio-11: Protected Tree Removal. One or more mature blue gum trees within the ornamental woodland habitat may satisfy size requirements for a “protected tree” under the City of South San Francisco’s Tree Protection Ordinance. Trees are considered protected if they are 48 inches or more at 54 inches above the natural grade. These trees, while providing some wildlife habitat, are non-native invasive trees that severely degrade natural habitats. Eucalyptus species outcompete native species and produce leaf litter that reduces the diversity and cover, and can alter fire regimes within the associated woodland understory. If any of these trees are found to be of sufficient size to be considered protected under the City’s ordinance, a permit will be required for their removal. However, due to the low habitat functions and values provided by these trees, their loss, and the loss of potential nesting, roosting, and foraging opportunities associated with them, this is considered a less- than-significant impact. No mitigation warranted. Less than Significant Impact Geo-1: Surface Fault Rupture. According to the latest available maps, the OPSP site is not contained within an Alquist-Priolo Earthquake Fault Zone boundary. Published geologic maps of the area show the San Andreas fault (the closest known fault to the site) as lying about 7.3 kilometers (4.5 miles) to the west. The potential impact of surface fault rupture is considered less- than-significant. No mitigation warranted. Less than Significant Impact Geo-15: Expansive Soils. Available existing geotechnical information for the OPSP site does not identify the presence of highly- plastic, near-surface expansive soils. Therefore, at this time the impact of expansive soils with respect to shallow foundations is considered to be less-than-significant. This applies to the entire OPSP, including the Phase I Project. No mitigation warranted. Less than Significant Impact GHG-1: Construction-Period GHG Emissions. Temporary construction-related exhaust would be an additional source of GHG emissions that could contribute to significant impacts on the environment. This is a less-than- significant impact. Although the impact is less-than-significant, BAAQMD recommends implementation of best management practices to further reduce construction-period GHG impacts. GHG-1: Construction GHG Reduction Measures. The following best practice measures shall be included in construction contracts to reduce GHG emissions during construction, as feasible. • At least 15 percent of the fleet of construction vehicles/equipment shall be alternative fueled (e.g., biodiesel, electric). • At least 10 percent of the building materials shall be locally sourced. Less than Significant DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 2-58 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance • At least 50 percent of construction waste or demolition materials shall be recycled or reused. Impact Haz-7 Airport Land Use Plan. The OPSP would be located within the jurisdiction of the Airport Land Use Plan for the San Francisco International Airport. According to the East of 101 area plan, the most stringent height limits in South San Francisco are south of Forbes Boulevard and Lindenville (the area between Railroad Avenue, South Spruce Avenue, and San Mateo Avenue), which is south of the site. Federal Aviation Regulations, Part 77, limits building heights to an elevation of 161 feet above mean sea level, approximately 12 to 14 stories, in the most restricted areas, increasing at a slope of 20:1 to a height of 361 feet above mean sea level. Since the tallest building portion would not exceed 161 feet in height, the OPSP would be in compliance with the Airport Land Use Plan. The impact of the OPSP on the Airport Land Use Plan is less-than-significant with no mitigation warranted. No mitigation warranted. Less than Significant Impact Haz-8: Cumulative Hazardous Impacts. The OPSP would be one of numerous sites, some of which are also existing hazardous materials sites that are anticipated to undergo development/redevelopment in the vicinity. The OPSP would contribute to a cumulative increase in the number of sites handling hazardous materials, and would result in a cumulative increase in transportation, use, disposal, and potential for exposure to and/or accidental release of hazardous materials during both construction and operations. However, the cumulative impact is expected to be slight and identified project- specific mitigation measures would reduce this impact to a less-than-significant level with no additional mitigation required. No mitigation warranted. Less than Significant Impact Hydro-4: Risk of Flooding. The OPSP is not located within the vicinity of a levee, nor in a potential flood path of a dam failure. The OPSP is located on the coast of the San Francisco Bay and therefore could potentially be at risk of flooding due to climate-induced sea level rise. However, grading changes proposed as a part of the Phase I Project would reduce the potential of flooding to a less-than-significant impact. No mitigation warranted. Less than Significant Impact Hydro-5: Inundation by Tsunami. Tsunamis, or tidal waves, are huge sea waves that are caused by seismic activity or other disturbance of the ocean floor. Portions of South San Francisco that are near the bay and low-lying are considered to be at risk for inundation by tsunami wave run-up. Wave run up is estimated at 6 feet above mean sea level for a 500-year tsunami. The margins of the OPSP area No mitigation warranted. Less than Significant CHAPTER 2: EXECUTIVE SUMMARY AND IMPACT OVERVIEW OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 2-59 Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance immediately border the bay waters. As such, a fringe of area is at or below 6 feet above mean sea level. However, development plans to not include development of the margins of the site that are at or below 6 feet above mean sea level. In addition, much of the shoreline of the OPSP area is protected by rip-rap to prevent damage to the shoreline by wave run-up. Consequently, this impact would be less-than-significant with no mitigation required. Impact Hydro-6: Cumulative Impacts on Hydrology and Water Quality. The increased construction activity and new development resulting from the OPSP, in conjunction with other foreseeable development in the city, would result in less-than-significant impacts on hydrology and water quality conditions with no additional mitigation measures necessary. No mitigation warranted. Less than Significant Impact Noise-1: Noise Levels at Proposed Uses. The OPSP will not expose persons to or generation of noise levels in excess of standard established by the City of South San Francisco. This is a less-than-significant impact. No mitigation warranted. Less than Significant Impact Noise-2: Projected Noise Increases. Following construction, the OPSP will not create a substantial permanent increase in ambient noise levels in the project vicinity above existing without the project. This is a less-than-significant impact. No mitigation warranted. Less than Significant Impact Noise-3: Cumulative Noise Increases. Traffic volumes along roadways serving the OPSP area will increase as a result of cumulative growth planned in and around the City of South San Francisco. The OPSP would not make a “cumulatively considerable” contribution to cumulative traffic noise increases at noise sensitive receptors within the OPSP area. This is a less-than-significant cumulative impact. No mitigation warranted. Less than Significant Impact Noise-4: Groundborne Vibration. The OPSP is not anticipated to expose persons to or generation of excessive groundborne vibration or groundborne noise levels. This is a less-than- significant impact. No mitigation warranted. Less than Significant Impact Noise-6: Aircraft Noise. Proposed uses developed at the site would be exposed to intermittent noise from aircraft associated with San Francisco International Airport. The exterior noise environment at the OPSP area would be considered compatible with proposed sensitive uses. This is a less-than-significant impact. No mitigation warranted. Less than Significant Impact Pop-1: Indirect Population Growth. As a large employment center, build-out of both Phase I Project and the entire OPSP would indirectly induce population growth through creation of additional jobs. However, these additional jobs No mitigation warranted. Less than Significant DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 2-60 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance would help in part to correct job deficiencies region-wide and the impact would be considered less-than-significant. Impact Traf-3: Bicycle Lane. Class II bicycle lanes will be provided along Oyster Point Boulevard and Marina Boulevard their entire lengths internal to the OPSP site. The Bay Trail bike/pedestrian path will also be completed internal to the OPSP site. The Phase I TDM conceptual site plan shows that bike parking areas will be provided within the building’s garage.

Year 2015 Base Case + Phase I Project and AM and PM peak hour volumes and roadway geometrics expected internal to the project site along Oyster Point Boulevard and Marina Boulevard (with Phase I development) are presented in Figure 16 in Appendix E. Analysis has been conducted of the Oyster Point Boulevard / Marina Boulevard and Marina Boulevard / Phase I access/Bayfront parking lot intersections assuming all-way stop control at each intersection. As shown in Table 16.21 below, both intersections should operate acceptably with projected year 2015 volumes, including development of the Phase I Project. This would be a less-than-significant impact, therefore no mitigation is required. No mitigation warranted. Less than Significant Impact Traf-15: On-Ramp Operation. Phase I Project traffic would not produce a significant impact at any on-ramp (see Table 16.7). This would be a less-than-significant impact, therefore no mitigation is required. No mitigation warranted. Less than Significant Impact Traf-16: Freeway Mainline Operation. No U.S.101 mainline segment would receive a significant impact due to the addition of Phase I Project traffic to year 2015 Base Case volumes. Operation would remain LOS D or better at all locations (see Table 16.13). This would be a less-than-significant impact, therefore no mitigation is required. No mitigation warranted. Less than Significant Impact Util-1: Increased Water Demand. Build- out of the OPSP area would increase water demand and use of the local water system. However, according to the Water Supply Assessment and Utilities Study, there is sufficient water supply through the year 2030, including the increased demand from the OPSP, and adequate water system capacity. This is a less-than- significant impact. No mitigation warranted. Less than Significant CHAPTER 2: EXECUTIVE SUMMARY AND IMPACT OVERVIEW OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 2-61 Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance Impact Util-3: Increased Wastewater Treatment Demand. Build-out of the OPSP area would increase wastewater flows and increase demand at the South San Francisco-San Bruno Water Quality Control Plant. However, according to the South San Francisco/San Bruno Water Quality Control Plant Draft Facilities Plan Update, there is sufficient capacity through the year 2030, including a reserve capacity for flows from the East of 101 area. As the wastewater treatment plant has adequate capacity to serve the OPSP’s projected demand, this increased demand is a less-than-significant impact. No mitigation warranted. Less than Significant Impact Util-4: Increased Impervious Area. OPSP area build-out will increase the impervious area by two acres, or 2.6 percent, which could result in increased stormwater flows and/or runoff not meeting treatment requirements, without appropriate on-site controls. However, the potential for increased flows will be mitigated through required compliance with the NPDES permit process, which will require such controls. Additionally, stormwater controls are proposed to meet or exceed LEED standards. The OPSP would not require additional off-site storm water facilities or fail to meet treatment requirements. This is a less-than-significant impact. No mitigation warranted. Less than Significant Impact Util-5: Increased Solid Waste Disposal Demand. The OPSP would increase solid waste generation at the site but would be served by a landfill with sufficient permitted capacity to accommodate the OPSP’s solid waste disposal needs, and would not impede the ability of the City to meet the applicable federal, state and local statutes and regulations related to solid waste. The OPSP would have a less-than- significant impact with no mitigation warranted. No mitigation warranted. Less than Significant Impact Util-6: Increased Energy Consumption. The OPSP would have an incremental increase in the demand for gas and electrical power given the increase in development in the OPSP area. However, the OPSP is expected to be served with existing capacity and would not require or result in construction of new energy facilities or expansion of existing off-site facilities and would not violate applicable federal, state and local statutes and regulations relating to energy standards. Additionally, buildings in the OPSP are proposed to meet or exceed LEED standards. The OPSP would have a less-than-significant impact relating to energy consumption with no mitigation warranted. No mitigation warranted. Less than Significant DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 2-62 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT This page intentionally left blank. OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 3-1 3 PROJECT DESCRIPTION INTRODUCTION The City of South San Francisco and a private developer are proposing a public-private redevelopment of approximately 80 acres in the proposed new Oyster Point Specific Plan area for research and development, office, commercial, hotel, recreational, and public open space uses (“OPSP”). The OPSP consists of (1) certain private and public improvements to be constructed in an initial phase of development, described in more detail below, which are analyzed on a project level in this EIR (“Phase I Project”), (2) additional private and public improvements to be constructed in later phases of development, which are analyzed on a programmatic level (including the Phase I Project), and (3) amendments to the Redevelopment Plan for the Downtown/Central Redevelopment Project. This chapter describes the OPSP location, site conditions and existing uses, specific elements of the OPSP and the Phase I Project, OPSP objectives, and intended uses of the EIR OYSTER POINT SPECIFIC PLAN LOCATION The site of the Oyster Point Specific Plan, including the Phase I Project and all subsequent phases of development (collectively, the “OPSP”) is part of the City of South San Francisco’s “East of 101” planning area, the traditional and continued core of South San Francisco’s industrial and technological businesses, including bioscience offices. The East of 101 area consists of roughly 1,700 acres of land bound by San Francisco Bay on the east side, Highway 101 and railway lines on the west, the City of Brisbane and San Francisco Bay on the north, and San Francisco International Airport on the south. The area has a mix of land uses, including industry, warehousing, retail, offices, hotels, marinas, and bioscience research and development facilities. The area is also separated from most of South San Francisco’s residential uses by U.S. 101 though some live-aboard boats are permitted at the two marinas located on Oyster Point and Oyster Cove marinas. The approximately 80-acre Plan site is located about 3/4 of a mile east of Highway 101, at the eastern end (Bay side) of Oyster Point and Marina Boulevards. Its location is shown in Figure 3.1. As more fully described in the following pages, the first phase of the OPSP (“Phase I Project”) will be analyzed on a project level, while subsequent phases of the OPSP will be analyzed on a programmatic level. Amendments to the Redevelopment Agency’s fiscally merged Redevelopment Plans, including the Downtown/Central Redevelopment Plan are also proposed. SITE CONDITIONS AND EXISTING USES The OPSP site includes areas commonly known as the Oyster Point Business Park and the Oyster Point Marina. The Oyster Point Business Park encompasses 25 acres of the OPSP area. It is a privately owned series of five single-story light-industrial buildings at 375/377, 379, 384, 385 and 389 Oyster DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 3-2 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Point Boulevard that were developed in the early 1980s totaling 403,212 square feet of space with surrounding parking (see Figure 3.2). Currently, these buildings are occupied by a variety of light industrial, office, and Research and Development (R&D) tenants. The 48-acre area known as the Oyster Point Marina area fills the remainder of the OPSP area other than roadway elements, which complete the 80-acre area. This land served as a municipal landfill for the City of South San Francisco from 1956 until it stopped accepting waste in 1970. The Marina is owned by the City of South San Francisco and managed through a Joint Powers Agreement with the San Mateo County Harbor District. Currently, this area hosts a variety of uses including a dry boat storage area, a marine support services building, two small office buildings, a 30-room inn and banquet hall, a bait and tackle shop, a boat and motor mart and a yacht club, all totaling 74,360 square feet. The remaining area is vacant or serves as parking for the docks, boat ramp, and the Bay Trail at the Oyster Point Marina area (see Figure 3.2). The Oyster Cove Marina is privately owned and located to the west of the Oyster Point Business Park; it contains 235 berths. The Oyster Point Marina is located on the north side of the Oyster Point Marina area and contains 600 berths, a boat ramp, fuel dock and fishing pier. The South San Francisco Ferry Terminal with service to/from San Francisco and the East Bay is currently under construction and scheduled to be completed at the Oyster Point Marina in early 2011. (The Ferry Terminal is shown on the Specific Plan Development Program, Figure 3.3). This Ferry Terminal is a separate project with its own environmental review. As the Ferry Terminal project is currently underway, it has been assumed for this analysis that the Ferry Terminal will be operational. OYSTER POINT SPECIFIC PLAN DESCRIPTION PROGRAMMATIC SPECIFIC PLAN As it is proposed, the OPSP will be a public and private redevelopment, consisting of the following, as shown on Figure 3.3. When specific reasonable development assumptions were needed for analysis, those shown in Table 3.1 were used. Private development including new office/research and development (R&D) buildings in the western portion of the site: x demolition of the existing inn located at 425 Marina Drive, the office buildings at 360 Oyster Point Boulevard and 401 Marina Boulevard, the boat and motor mart at 671 Marina Boulevard, the Yacht Club at 911 Marina Boulevard, and the light-industrial buildings at 375-389 Oyster Point Boulevard, x new public roadway alignment (and utility infrastructure) of Oyster Point Boulevard and Marina Drive, including relocation of sewer pump station #1 adjacent to 377 Oyster Point Boulevard, x office/R&D buildings with a Floor Area Ratio (FAR) of up to 1.25 across the 41 acres of private land area, totaling up to 2,300,000 square feet of building space, including 10,000 square feet of accessory commercial uses, x four phases of office/R&D uses of approximately 500,000 to 700,000 square feet each, x each phase will include or have access to courtyards, plazas, shuttle bus stops, and/or structured parking, CHAPTER 3: PROJECT DESCRIPTION OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 3-3 Table 3.1: Development Assumptions Building Size (square feet if not otherwise specified) Uses to Remain Oyster Point Bait and Tackle 1,440 Oyster Cove Marina 235 berths Oyster Point Marina 600 berths Phase I Office/R&D Building 508,000 to 600,000 Auxiliary Commercial 10,000 Oyster Pt Marina Beach approximately 3.1 acres Recreation Area approximately 3 acres Additional Phases New Hotel(s) 350 rooms Commercial/Retail/Restaurant in Hotel40,000 Office/R&D Building (Phase II) 700,000 Office/R&D Building (Phase III) 525,000 Office/R&D Building (Phase IV) 517,000 Uses to Remain until Hotel Construction, then be Rebuilt on Site Oyster Point Yacht Club 4,000 Oyster Point Maintenance 2,500 Note that a split of 40% Office and 60% Research & Development uses was assumed for all Office/R&D buildings. No office/research & development has been assumed on the proposed City-owned portion, however, such development would be allowed under the proposed changes to the General Plan and zoning. Any potential office/research & development on City-owned portion would be subject to subsequent environmental review. x dedication and construction of an approximately 3.1 acre parcel for use as waterfront public open space. x Site preparation and/or construction on the former landfill site will involve disturbance and relocation of landfill refuse on-site (or off-site if the material is hazardous) and modifications to the landfill cap, as more fully described under the Phase I Project description below. Public redevelopment including public open space, recreation fields, marina improvements, and a hotel: x one or two hotels with a total of 350 rooms and 40,000 square feet of retail/restaurant, as well as replacement of the Yacht Club (4,000 square feet) and maintenance building (2,500 Square feet), x new road and utility infrastructure to serve the future hotel site and Oyster Point Marina area, x a flexible-use recreation area, x reconfiguration of parking adjacent to the new ferry terminal and shuttle bus turnaround proposed with the ferry terminal, x improvements to the Bay Trail and surrounding open space throughout Oyster Point Marina and the proposed office/R&D Project (subject to BCDC Guidelines and approval), DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 3-4 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT x possible changes to two of the docks in the Oyster Point Marina, which could include removal and replacement, x enhancement (landscape and other cosmetic improvements) of existing uses at the eastern end of Oyster Point in conjunction with required landfill cap repairs, and x roadway connections to the South San Francisco Ferry Terminal, which is currently under construction. x site preparation and/or construction on the former landfill site will involve disturbance and relocation of landfill refuse on-site (or off-site if the material is hazardous), as more fully described under the Phase I Project description below. PHASE I PROJECT The first phase (“Phase I Project”) of the OPSP will include the development of a minimum of 508,000 square feet up to a maximum of 600,000 square feet of office/R&D space attached to a parking garage structure on approximately 10 acres, creation of waterfront open space, construction of the flexible recreation area, grading of most of the future hotel site, and construction of new roads serving Oyster Point Marina. The specific details of the Phase I Project work are outlined below and in the attached Phase I Site Plan, Figure 3.4. Office/R&D buildings on Developer’s Land (Private Development) Demolition x Phase I will include demolition of the four existing buildings totaling 66,420 square feet, including the Oyster Point Inn at 425 Marina Drive, two Office buildings at 360 Oyster Point Boulevard and 401 Marina Boulevard, and the boat and motor mart at 671 Marina Boulevard. Landfill Consolidation and Grading x Site preparation and building construction in Phase I will involve excavation and relocation of up to approximately 100,000 to 120,000 cubic yards of uncompacted landfill materials. Almost all of this material is anticipated to be non-hazardous and will be relocated on-site in accordance with an approved grading plan. Approximately 10,000 cubic yards of potentially hazardous material is anticipated. Any excavated hazardous material will be relocated off-site for appropriate disposal. The Phase I Grading and Drainage Plan is included as Figure 3.5. Site and Massing (see Figure 3.4: Phase I Site Plan and Figures 3.6 and 3.7: Elevations): x The Office/R&D buildings will occupy a site of approximately 10 acres to the south of Oyster Point Boulevard directly east of Gull Drive. x Phase I will include the construction of between 508,000 to 600,000 square feet of office/R&D space. x Office/R&D complex will include three office/lab buildings, the western-most of which could reach up to 10 stories, the other two of which could reach up to 6 stories. x Buildings will be located on a plaza, which will attached to a parking garage structure. CHAPTER 3: PROJECT DESCRIPTION OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 3-5 Access: x The building entrances and lobbies will be located at plaza level. x A shuttle stop and passenger drop off will be located at plaza level off Oyster Point Boulevard. x Access to the parking garage will be through an entrance/exit at the northeastern corner of the garage off of Marina Boulevard. x Service entries and loading docks for each building will be accessed at the southwest corner of the site off of Gull Drive. Open Space and Infrastructure Improvements on City’s Land (Public Redevelopment) Roads: x Phase I will include the reconfiguration of Marina Boulevard and a portion of Oyster Point Boulevard. x The new roadway construction will also include bicycle lanes, sidewalks and street trees. x Utilities will be provided in the new roads and will be sized for the full build-out of all phases including sewer, water, fire water, and a joint trench for PG&E and telecom, as shown on Figure 3.9: Utilities Plan. x The parking lot adjacent to the west basin of Oyster Point Marina will be reconstructed after landfill cover improvements have been completed to access the new Marina Boulevard configuration (see Figure 3.4: Phase 1 Site Plan). Landfill Cover: x Improvements will be constructed to update the landfill cover to current regulatory requirements (Title 27), as shown on Figure 3.10: Landfill Improvement Plan. Open Space/Recreation: x An approximately 3-acre site to the east of the Office/R&D buildings will be graded and constructed as a flexible-use recreation area, which are to be programmed by the City of South San Francisco. (See Figure 3.4) x An approximately 3.1-acre waterfront site to the north and east of the Oyster Point Boulevard and Marina Boulevard intersection will be graded and landscaped as a public park per City Specifications (See Figure 3.4) and BCDC design guidelines. x Off-street pedestrian paths (including new portions of the Bay Trail) will connect the ferry terminal to the existing Bay Trail Future Hotel Site: x The approximately 4.7-acre site to the east of the recreation area will be graded to allow for a future hotel and retail complex. To the east of this area, the Yacht Club structure and the Harbor District garage, yard and access would remain intact throughout Phase I. (See Figure 3.4) DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 3-6 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT REDEVELOPMENT PLAN AMENDMENTS Amendments to the South San Francisco Redevelopment Agency’s fiscally merged Redevelopment Plans are also proposed for approval, in order to (1) combine the fiscal limit on the amount of outstanding debt for the Downtown/Central Redevelopment Plan Added Area, which includes the Oyster Point Marina area, with the overall debt limit for the other fiscally merged redevelopment project areas, (2) increase the time period to incur debt for the Downtown/Central Redevelopment Plan Added Area and the El Camino Redevelopment Plan Added Area by ten years, and (3) refine the methodology for allocation of revenues towards the combined tax increment collection limit for the fiscally merged Project Areas that are subject to such limit to exclude housing set-aside, pass-through payments and state take-aways (SERAF). The changes could potentially help fund a number of redevelopment projects already contemplated for the City’s various project areas. For the reasons stated below and as documented in the following discussion, additional CEQA review of these projects—to the extent such review has not already been completed—is not required at this time, and therefore is not included as part of the EIR for the OPSP. The development and construction of such projects is not related to the OPSP. Most of the other projects that may ultimately be funded pursuant to the Downtown/Central Redevelopment Plan Amendments are not proposed for approval at this time, and no entitlements for such projects will be issued as part of any approval for the OPSP. While some of the redevelopment projects are in the process of being constructed (following separate CEQA review), the timing, scope, and precise design of many of the projects is still unknown. The Downtown/Central Redevelopment Plan Amendments proposed as part of the OPSP will simply operate as a funding mechanism for the other potential redevelopment projects that are unrelated to the OPSP development. Government funding mechanisms or other government fiscal activities that do not involve any commitment to any specific project are not considered a “project” requiring CEQA review. (CEQA Guidelines, § 15378(b)(4).) A “project” requiring CEQA review, is an activity that has the potential for resulting in either a direct or reasonably foreseeable indirect physical change in the environment. Accordingly, potential redevelopment projects that have not been approved, but that may be funded by the proposed Downtown/Central Redevelopment Plan Amendments to the extent the funding is not solely for the OPSP projects, will be subject to a separate CEQA analysis at the time that a particular scope and design for the project is proposed, as that is the time that the potential projects could result in a physical change in the environment. In some cases, the redevelopment project has already been approved and is under construction, and therefore, has been subject to separate CEQA review. Table 3.2 identifies completed and in-progress redevelopment projects for which separate, individualized CEQA review has already been completed. To the extent that any CEQA review of potential future redevelopment projects is required, it is important to note that the CEQA impacts of many of the potential future redevelopment projects that will be funded by Amendments were analyzed in certified EIRs at the time the corresponding Redevelopment Plan, or previous amendments thereto, were proposed for adoption. Once an EIR has been certified for a redevelopment plan, individual components of the redevelopment plan and subsequent activities within the scope of the redevelopment plan are subject to limited CEQA review. (CEQA Guidelines, § 15180.) As particular development projects are proposed, their potential impacts will be evaluated against the impacts analyzed in the certified EIRs to determine what, if any, CEQA analysis is still required. Table 3.3 identifies potential redevelopment projects that may be funded by the OPSP Redevelopment Plan Amendments, and the previous CEQA documents in which the particular projects were analyzed. This EIR for the OPSP development, including associated Redevelopment Plan Amendments, expressly relies on the analyses contained in the CEQA documents identified in Tables 3.2 and 3.3. The CHAPTER 3: PROJECT DESCRIPTION OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 3-7 CEQA documents identified in Tables 3.2 and 3.3 are in the custody of the City’s Chief Planner, and are available for review during normal business hours at the City of South San Francisco Planning Division, 315 Maple Avenue, South San Francisco, CA 94080. This EIR for the OPSP development expressly relies on the tiering procedures described in the CEQA Guidelines, Sections 15152, 15153, and 15180.

It is not yet known if or when these projects will be constructed; if they are ever to be constructed, the scope and design plans for these projects are also unknown at this time. In accordance with CEQA, the degree of specificity with which an EIR must analyze impacts, should correspond to the degree of specificity associated with the underlying activity described in the EIR. (CEQA Guidelines, § 15146.) CEQA does not require a lead agency to speculate as to the impacts of an activity which may be unforeseeable. (CEQA Guidelines, § 15144-15145.) Accordingly, the level of detail in the analysis of a project proposed for construction will be greater than the level of detail in the analysis of the secondary effects DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 3-10 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT that can be expected to follow from the adoption or amendment of a land use plan. (CEQA Guidelines, § 15146.) Here, the potential redevelopment projects that may be funded by the OPSP Redevelopment Plan amendments are not proposed for construction at this time, but rather are the “secondary effects” of the funding mechanism that will be created by the proposed Redevelopment Plan amendments. Therefore, the appropriate time for CEQA review of these remaining potential redevelopment projects is when a specific development and construction proposal is prepared for approval. At that time, the remaining potential redevelopment projects that have not already been subject to environmental review, will be analyzed in a separate CEQA document. Nevertheless, to the extent that certain impacts of these remaining potential redevelopment projects are foreseeable at this time, analysis of such impacts have been incorporated, at a programmatic level, into the analysis of the OPSP development. Analysis of the impacts on population and housing and the growth-inducing impacts of the entitlements currently proposed for approval, for example, include analysis of the impacts of the remaining potential redevelopment projects.

It may also have long term lasting effects on the evolution of the urban area, thereby stimulating growth and increasing its attractiveness for new or expanding businesses, residential development or other desired or planned land uses. On the other hand, new development can change the character of an area by disrupting the visual and aesthetic features that establish the identity and value of an urban area for its existing residents, merchants or other users. Loss of such identity and value may discourage new investment, continued residency or business activity or other activities that attract visitors to the area. A single new development can add to a district’s appeal and complement adopted goals for development and change or entirely overwhelm a district’s scale and visual landmarks. Over time, a new development may become a valued component of the district and its identity, or generate dissatisfaction by residents, visitors, employers and employees. The visual value of any given feature is highly subject to personal sensibilities and variations in subjective reaction to the features of an urban area. A negative visual impression on one person may be viewed as positive or beneficial by another. Objective or commonly agreed upon standards are difficult to establish, but an extensive body of literature is devoted to the subject of urban design and visual aesthetics. REGULATORY SETTING FEDERAL There are no federal statutes related to aesthetics that would apply to the proposed OPSP. STATE Caltrans Scenic Highway Program California’s Scenic Highway Program is administered by the California Department of Transportation (Caltrans). The Scenic Highway Program was created by the Legislature in 1963. Its purpose is to protect and enhance the natural scenic beauty of California highways and adjacent corridors, through special conservation treatment. A highway may be designated scenic depending upon how much of the natural landscape can be seen by travelers, the scenic quality of the landscape, and the extent to which development intrudes upon the traveler's enjoyment of the view. The State Scenic Highway System includes a list of highways that are either eligible for designation as scenic highways or have been officially designated. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 4-2 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Within South San Francisco, sections of Interstate-280 (I-280) have been designated as scenic corridors under the State Scenic Highway program, however, these are not in the vicinity of the OPSP site. U.S. 101 has not been designated or identified as eligible in the vicinity.1 LOCAL Aesthetic and visual resource regulations must be identified on a project-by-project basis. Potentially pertinent local aesthetic policies currently in place are listed below under their respective plan or ordinance. Many of the aesthetic-related policies are broader-reaching than simply to avoid environmental impacts. Note that the following impact section will analyze the potential for environmental impacts related to aesthetics and does not replace the design review process or prevent decision-makers from determining an inconsistency with policies in the future during that process. South San Francisco General Plan (1999) The City of South San Francisco General Plan describes goals and policies for future growth and development throughout the City. The General Plan governs the maximum amount and intensity of development within the East of 101 area, including the OPSP site. Policies pertinent to aesthetics are listed below: 2-I-3 Undertake planned development for unique projects or as a means to achieve high community design standards, not to circumvent development intensity standards. 2-I-4a Establish design requirements to achieve an FAR bonus as set forth in Table 2.2-2. 2-I-8 As part of establishment of design guidelines and standards, and design review, improve the community orientation of new development. 2-I-9 Ensure that any design and development standards and guidelines that are adopted reflect the unique patterns and characteristics of individual neighborhoods. 5.1-1-8 Improve the accessibility and visibility of Sign Hill Park and the bayfront. Appropriate departments in the City should study issues of access, safety and protection of surrounding neighborhoods in conjunction with enhanced access programs to assure greater use of Sign Hill Park does not create unacceptable impacts to surrounding areas. East of US 101 Area 3.5-G-2 Direct and actively participate in shaping the design and urban character of the East of 101 Area. 3.5-G-3 Promote campus-style biotechnology, high-technology, and research and development uses. 3.5-I-4 Unless otherwise stipulated in a specific plan, allow building heights in the East of 101 area to the maximum limits permissible under Federal Aviation Regulations Part 77. 1 California Department of Transportation, Scenic Highway Program, Eligible and Designated Routes, website: http://www.dot.ca.gov/hq/LandArch/scenic_highways/scenic_hwy.htm, accessed on November 6, 2010. CHAPTER 4: AESTHETICS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 4-3 East of 101 Area Plan (adopted 1994) The OPSP site is also located within the East of 101 Area Plan, a detailed implementation guide for the area. The East of 101 Area Plan principally provides direction related to design and certain other facets of development in the area not otherwise covered in the General Plan or other City plans. The City will use consistency with these policies in evaluating proposals for new development. Policies potentially pertinent to the aesthetics of projects in the OPSP are listed below: Land Use LU-2 New land uses that are similar to or compatible with surrounding development are encouraged. New developments should visually enhance and contribute to the aesthetic character of the East of 101 Area. LU-23 Maximum heights of buildings in the East of 101 Area shall not exceed the maximum heights established by the Airport Land Use Commission based on Federal Aviation Regulations Part 77 Criteria. Edges DE-2 Projects in the vicinity of US 101 should be designed with the freeway in mind. Visual Landmarks DE-5 Developments in the East of 101 Area should be designed to take advantage of views of San Francisco Bay and Point San Bruno Hill with its “Windchime” [now known as the Wind Harp]. Wherever possible, open space areas should be designed to provide views of these areas, and any new roadways should be laid out to provide vistas of them as well. Note that the East of 101 Area Plan also includes an Open Space and Recreation goal related to views: Goal 4.3 Preserve and enhance the natural amenities and features of the East of 101 Area including the views of the San Francisco Bay , San Bruno Mountain, and San Bruno Point Hill. However, there are no relevant implementing policies other than DE-5 above and the only vista point identified in the Plan is at the southwestern corner of the East of 101 Plan Area (not near the OPSP area), where a view of the Bay and Airport operations are available. DE-6 Within each development a landmark building should be encouraged to mark the project approach for visitors coming to it. Such landmarks shall not include signs. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 4-4 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Parking, Loading, and Access Design DE-15 Site design should de-emphasize the visual prominence of parking areas by separating parking areas into relatively small components and locating parking behind buildings whenever possible. The standard practice of placing the majority of the parking between the building and the main street frontage should be avoided when possible, as shown in Figure B [of the East of 101 Area Plan]. DE-16 All loading and service areas shall be designed so that the maneuvering of vehicles can be accomplished on-site without special effort and without disrupting on-site circulation. DE-17 In all land use categories except Light Industrial, loading docks and service areas should be located at the rear or side of the development, and should be separated from automobile parking areas. DE-20 Projects should be designed to minimize driveways and vehicular circulation areas, while maximizing outdoor public spaces. For example, owners of adjacent properties could develop shared facilities such as driveways, pedestrian plazas and walkways. Site Design and Open Space DE-21 Developments should include a landscaped buffer zone along property lines that is appropriate to the land use category, as shown in Figure A and specified in Section D of the Design Element [of the East of 101 Area Plan]. DE-22 Developments in the Planned Commercial, Planned Industrial and Coastal Commercial categories should include on-site open space as a unifying element and as areas for employee use. Open space should be continuous and should connect separate buildings or sites, especially in campus-like developments, as shown in Figure B. Open spaces should particularly be located adjacent to lunch rooms and conference rooms. DE-23 Open space should be located and designed with consideration for sun exposure and wind protection. Where possible, open space should offer seating areas with views of San Francisco Bay and Point San Bruno Hill. Landscaping and Lighting DE-28 CHAPTER 4: AESTHETICS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 4-5 Plant species chosen for the area should include low maintenance plants and plants adaptive to the extremes of climate in the area. In addition, plant species and planting design should complement the design of the development. DE-29 Lighting on the exteriors of buildings should be incorporated into the overall building and landscape design. Security and entry lights should align with, be centered on, or otherwise coordinate with the building elements. Building Design DE-38 The form and location of structures, the use of building colors and materials, and the selection of landscape materials and street furniture shall consider the overall context of the project and promote the development of a sense of identity for the East of 101 Area. DE-39 All sides of buildings that are visible from a public street or area should be detailed and treated with relief elements and changes in plane. Architectural elements used to provide relief could include awning projections, trellises, built in planters, integrated plazas, colonnades or arcades, expression of structural elements, wall/window recesses and/or projections, changes in materials and textures or elements/treatments that create patterns of shade/shadow. Blank walls should be avoided. In addition to the specific policies mentioned above, the East of 101 Area Plan also lists guiding policies to control the design of individual buildings, sites, and streetscape, including policies related to parking, loading, and access design; landscaping and lighting; utility lines; fencing and screening; open space; and signage. DE-41 Building facades should be constructed of durable materials such as those already used in the area, including stucco, well-detailed tilt-up concrete or metal panels, and decorative masonry. Within a limited range, building surfaces should incorporate more than one material or texture. Highly reflective materials are discouraged. Building materials shall be chosen to weather the salt air in the area, and shall be subject to review by the Design Review Board and the approval of the Chief Planner. Additional policies for the Light Industrial and Coastal Commercial categories are included in Section D of this Design Element. DE-42 Building color pallets shall be as approved by the applicable City body with the advice of the Design Review Board. Building colors may include earth tones and appropriate pastels. Bright colors and simple primary colors should be avoided, except as accents. Within a limited range, building surfaces should incorporate more than one color. DE-43 DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 4-6 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Retail, flex and industrial buildings should not exceed 35 feet in height. Landmark design elements should not exceed 50 feet in height. Office buildings are not subject to a height limit other than that of the ALUC, as outlined in Policy LV-23. Additional restrictions on building height in the Coastal Commercial category are included in Section D of this Design Element. Exceptions to this policy may be made if warranted by a specific proposed use, or if taller building heights are included in an approved Master Plan. Rooftop Mechanical Equipment DE-52 Rooftop mechanical equipment should be screened from view by integral architectural elements such as pitched roofs, ornamental parapets, mansards or low towers, as shown in Figure A. If screening from all significant public viewpoints is not possible due to changes in grade, then the equipment should also be enclosed in a housing that is compatible with the design of the main building. DE-53 Mechanical equipment shall be painted to match the color of the roof where it is located. South San Francisco Municipal Code The zoning regulations for the Oyster Point Marina Specific Plan District would be substantially revised as part of the approvals required for the OPSP and will be replaced with zoning regulations for the new Oyster Point Specific Plan District. Development in the OPSP area will need to comply with permitted uses, height, bulk, setbacks, etc. under this zoning. SETTING South San Francisco’s urban character is one of contrasts within a visually well-defined setting. San Bruno Mountain to the north, the ridge along Skyline Boulevard to the west, and the San Francisco Bay to the east provide the city with distinctive edges.2 The city is contained in almost a bowl-like fashion by hills on two sides and the City of San Bruno to the south. The city’s terrain ranges from the flatlands along the water to hills west and north. Hills are visible from all parts of the city, and Sign Hill and San Bruno Mountain (which is outside city limits) in the distance are visual landmarks. Much of the city’s topography is rolling, resulting in distant views from many neighborhoods. Geographically, the city is relatively small, extending approximately two miles in a north-south direction and about five miles from east to west. South San Francisco’s industrial roots are reflected in its urban character, especially in its eastern parts. Almost 20 percent of South San Francisco’s land is occupied by industrial and warehousing uses. The OPSP area is located in the East of 101 planning area of South San Francisco. The East of 101 area was part of the first industrial development in South San Francisco over 100 years ago. Since then, the area has undergone many transformations. Pioneering industrial uses, such as steel manufacturing and meat packaging gave way to industrial park, warehousing and distribution uses that came to dominate the area in the 1950s and 1960s. The recent emergence of modern office buildings marks the third 2 City of South San Francisco, prepared by Dyett & Bhatia, South San Francisco General Plan: Existing Conditions and Planning Issues, 1997, p.4-2, 4-10, 4-15. CHAPTER 4: AESTHETICS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 4-7 major wave of land use change in the area. The newly emerging research and development and office areas are unique in their uses of consistent and conscious street tree planting. Older manufacturing uses, industrial park structures and tilt-up warehousing buildings can all be found in the area and blocks are generally very large in size. Major landmarks in the East of 101 Area include San Francisco Bay and Point San Bruno Hill, which has a large sculpture known as the Wind Harp at its peak. There is no dominant building character or streetscape pattern in the East of 101 Area. The scale of the built environment ranges from one to seven stories, with some larger ten- to twelve-story hotels and buildings in the area. The condition of the structures varies from dilapidated to virtually new. Land uses in the general vicinity of the OPSP area are mostly limited to office, research & development, commercial (including childcare facilities, fitness centers, restaurants), and light industrial uses. An existing two building office complex will remain at the terminus of Oyster Point Boulevard, to the north and east of the OPSP area. Site Description The approximately 80-acre OPSP site is located about 3/4 of a mile east of Highway 101, at the eastern end (Bay side) of Oyster Point and Marina Boulevards. Its location is shown in Figure 3.1. The OPSP site includes areas commonly known as the Oyster Point Business Park and the Oyster Point Marina area. The Oyster Point Business Park consists of a series of five single-story light-industrial buildings with surrounding parking. The Oyster Cove Marina is located to the west of the Oyster Point Business Park. The Oyster Point Marina area, a former municipal landfill, currently hosts a variety of uses including a dry boat storage area, a marine support services building, two small office buildings, a small inn and banquet hall, a bait and tackle shop, a boat and motor mart and a yacht club. The remaining area is vacant or serves as parking for the docks, boat ramp, and the Bay Trail. The Oyster Point Marina is located on the north side of the Oyster Point Marina area. (See Figure 3.2.) The South San Francisco Ferry Terminal with service to/from San Francisco and the East Bay is currently under construction and scheduled to be completed at the Oyster Point Marina in 2011. See Figure 3.3. Due to the relatively flat topography of the site and surrounding area, views from much of the OPSP area are largely restricted to short-range views of nearby structures, roadways and parking areas. However, surrounding development to the south can be viewed from some of the higher elevations toward the west of the OPSP area. In addition, there are direct Bay views to the northeast, east, and southeast, and long range views of the San Bruno Mountains and Sierra Point to the northwest. Because the sign on Sign Hill is located west of the site and faces south, it cannot be seen from the OPSP area or immediate vicinity. Photographs of the site in its existing condition can be seen in Figures 4.2a, 4.3a, 4.4a and 4.5a. Changes with the OPSP and Phase I Project The full description of the proposed changes can be found in Chapter 3: Project Description and was used to assess aesthetic impacts. The proposed changes can be summarized as follows: With development of the OPSP, the majority of existing building would be demolished and replaced with new buildings as development proceeds in phases. For visual modeling of the proposed structures, we have assumed “worst-case” massing. In this instance, that means that we have modeled all buildings DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 4-8 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT at the maximum heights anticipated in the OPSP area. In actuality, the buildings will likely vary in height and could not all be built out to these masses, as it would result in much greater square footage than is actually proposed to be permitted. Because the final design for the buildings under the OPSP are not known, this methodology provides a conservative analysis of potential aesthetic impacts. All Office/R&D development have been modeled as 10 stories (approximately 210 feet with podium level and rooftop screening). While it is difficult to determine the size of the parking garage structures as it will depend on specifics of future design, we have assumed footprints consistent with current conceptual plans and heights of 5 stories, which is conservative based on parking demand and provision assumptions. Note that relocation of landfill material on-site will change the grading within the OPSP and specifically within the vicinity of the landfill. This changed grading will be intended to correct landfill settlement and raise low areas to reduce the potential for flooding and counteract the adverse effect of sea level rise. Particularly in relation to changes in proposed building heights, these grade changes will not have a substantial impact on aesthetic-related impacts. While little is known of the potential design for the future hotel(s), a footprint consistent with current conceptual plans, 75 foot height, and basic hotel styles have been used for visual modeling purposes. Visual models of the proposed development can be seen in Figures 4.2 through 4.5, with the upper figure “a” showing the existing context and the lower figure “b” showing the visual modeling of the proposed development in that context. The map of viewpoint locations is included as Figure 4.1.

DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 4-14 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT This page intentionally left blank. CHAPTER 4: AESTHETICS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 4-15 IMPACTS AND MITIGATION MEASURES Standards of Significance The following thresholds for measuring aesthetic impacts are based upon CEQA Guidelines thresholds: 1.Would the project have a substantial adverse effect on a scenic vista? 2.Would the project substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway? 3.Would the project substantially degrade the existing visual character or quality of the site and its surroundings? 4.Would the project create a new source of substantial light or glare, which would adversely affect day or nighttime views in the area? SCENIC VISTA Impact Vis-1: Scenic Vista. Development of the OPSP area would result in new buildings of increased heights and size on the OPSP site, which would obstruct some views of the San Bruno Mountains and the San Francisco Bay from some locations, but would not significantly adversely impact views of any scenic vistas from public viewing points. Further, given the OPSP’s urban setting, a less-than-significant impact would result on scenic vistas with no mitigation warranted. Many prominent visual landmarks, such as the San Bruno Mountains, the San Francisco Bay, and the Wind Harp at San Bruno Point Hill are visible from properties in the East of 101 Area in South San Francisco, including from along the recreational Bay Trail. These landmarks are not designated scenic vistas, nor are there any identified vista point from which they are intended to be viewed in the vicinity of the OPSP area. CEQA generally protects against significant adverse impacts to public views of scenic vistas, taking into consideration whether the view is from a location at which people gather specifically to enjoy views and the environmental context (i.e., if the area is a natural area or a developed urban area). The following bullet points discuss of the impacts to views of these prominent visual landmarks. x The Wind Harp at Point San Bruno Hill is located over a half mile away, south of the OPSP area and is not fully visible due to the distance, grade difference, and buildings between. Development in the OPSP area would not significantly obstruct views of the Wind Harp. (No impact.) x The San Francisco Bay is a prominent view from the OPSP area, other parts of the city, and traffic along the U.S. 101. Figures 4.2 and 4.3 show existing southeast/easterly views in the first figure, labeled “a”, as well as how those views would be changed with development in the OPSP area as the second figure, labeled “b”. Development in the OPSP area would change views toward the Bay from private development to the west, from the traffic on U.S. 101 and from portions of the Bay Trail.Figure 4.6 shows nearby portions of the Bay Trail and the locations from which views toward the Bay could be further affected by development in the OPSP area. However, as can be seen in Figures 4.1 and 4.2, the topography of the area does not provide substantial views of the Bay, and most sightlines that could be affected by development in the OPSP are already blocked by existing development. . Therefore, the impact to views of the Bay would be less than significant. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 4-16 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT x The San Bruno Mountains can be seen from many locations throughout the city, including from the OPSP area, as seen in Figures 4.4 and 4.5. The second figures of these, “b”, show how construction under the OPSP may block out a portion of the existing northwestern and western views of the San Bruno Mountains from certain locations to the south of the OPSP area and from the Oyster Point Marina area within the OPSP, including from portions of the Bay Trail and the new Ferry Terminal. To provide a “worst case” analysis, the buildings were shown all to the maximum heights anticipated (while in actuality, less total building mass would be allowable and buildings would be anticipated to vary in height). The locations for the visual modeling were chosen specifically to show the most affected views. Most view locations would be affected to a lesser degree. Figure 4.6 shows nearby portions of the Bay Trail and the locations from which views of the San Bruno Mountains could be further affected by development in the OPSP area (the views are already affected by existing development and topography). While views toward the San Bruno Mountains would be affected by development in the OPSP area, the San Bruno Mountains are not designated as a scenic vista and the locations from which views are affected are not places where people gather in order to gain a view of the San Bruno Mountains. Proposed development in the OPSP area would block views from portions of the Bay Trail toward the San Bruno Mountains. However, while the Bay Trail is a recreational trail, it is intended to co-exist along development areas and there are no designated scenic outlooks of the Figure 4.6: The Bay Trail in the vicinity of the OPSP and the potential to affect views. CHAPTER 4: AESTHETICS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 4-17 San Bruno Mountains along these portions of the Trail, which would retain intended views of the Bay. Therefore, the impact to views of the San Bruno Mountains would be less than significant. There are no other scenic vistas or visual landmarks that would be affected by the proposed OPSP and, as discussed above, impacts on views of the San Bruno Mountain and San Francisco Bay would be considered less than significant. Therefore, development in the OPSP area would not be considered to have a substantial adverse effect on a scenic vista and the impact is less-than-significant. SCENIC HIGHWAYS As described in the Regulatory Setting section above, the OPSP area is not located in the vicinity of a scenic highway, and therefore would have no impact related to scenic resource damage on a scenic highway. VISUAL CHARACTER The visual character of the East of 101 area consists of a mixture of older and newer office and industrial buildings, with differing amounts of associated landscaping. Development in the Oyster Point Business Park portion of the OPSP area would involve replacement of older office/light industrial buildings with new construction of modern buildings with a high quality design including notable landscaping and pedestrian improvements. In the Oyster Point Marina area, existing buildings will be replaced with larger, newer buildings as well as a new park area adjacent to the Bay and a recreational area east of the Phase I office/R&D project. These changes will result in a highly visible change to the site. During construction, four basic types of activities would be expected. First, demolition of existing structures within the OPSP site would occur. Second, the sites would be prepared, excavated, and graded to accommodate the new building foundations. Next, new buildings and associated landscaping and site improvements would be developed. Visual impacts associated with construction activities would be temporary in nature as they would only exist for the duration of construction activities. Such temporary impacts would include exposed pads and staging areas for grading, excavation, and construction equipment. In addition, temporary structures could be located on the OPSP site during various stages of demolition or construction, within material storage areas, or associated with construction debris piles. While these activities would take place exclusively within the OPSP site, these visual impacts could affect surrounding land uses. In addition, automobiles traveling along area roads and the U.S. 101 could have short-term views of the OPSP site during construction. Pedestrians and bicyclists along the Bay Trail may also have short-term views of construction activity occurring on the site. However, this visual condition would be a temporary visual distraction typically associated with construction activities and equipment and would not be considered a significant impact. The height of buildings in the OPSP area are expected to substantially increase over the current situation to a scale on par with other office/R&D development in the East of 101 area. Representative visual modeling shown in Figures 4.2 through 4.5 depict the possible visual outcome. However, while the visual character would change, the construction of modern buildings meeting or exceeding the city’s design criteria would not “degrade the existing visual character or quality of the site.” The proposed OPSP would have no adverse impact on the visual character of the site or the East of 101 area. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 4-18 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT LIGHT AND GLARE Impact Vis-2: Light and Glare. The many windows and outdoor lights associated with increased development intensity within the OPSP area could potentially be substantial sources of nighttime light and daytime glare. This impact is potentially significant. Sources of light and glare in the OPSP vicinity include interior and exterior building lights, service areas and surface parking lots, and city street lights. Vehicular traffic along major thoroughfares in the area also create sources of light and glare. The existing level and sources of light and glare are generally typical of those in a developed urban setting. Development in the OPSP area as proposed would create new sources of light from interior lighting, exterior building illumination, lighted vehicle and pedestrian circulation, and emphasis for key architectural or landscape features and outdoor spaces. Illumination levels in the OPSP area will conform to regulatory requirements and recommendations of the Illumination Engineering Society of North America (IESNA) and be the lowest end of the range of illumination levels provided in the IESNA. This would maintain appropriate levels of light at building entries, walkways, courtyards, and parking lots at night consistent with minimum levels required by building codes. Nighttime security lighting would not be expected to substantially increase over current conditions. Lighting would be directed onto the specific locations intended for illumination and would be characteristic of existing lighting in the surrounding industrial areas. As the proposed OPSP calls for an increase in the density and height of development, nighttime light would increase if inappropriate levels of light are used or inappropriate lighting plans are implemented. However, development within the OPSP would comply with the guidelines in the Design Element of the East of 101 Area Plan, including those related to lighting, specifically Guidelines DE-29 and DE- 50. Mitigation Measure Vis-2a: Lighting Plan. Prior to issuance of building permits for each phase of construction within the OPSP, the applicant shall submit a Lighting Design Plan for review and approval by the City of South San Francisco Planning Department. The plan shall specify fixtures and lighting that maintains appropriate levels of light at building entries, walkways, courtyards, parking lots and private roads at night consistent with minimum levels detailed in the City’s building codes. These fixtures shall be designed to eliminate spillover, high intensity, and unshielded lighting, thereby avoiding unnecessary light pollution. At a minimum, the Plan shall include, but not necessarily be limited to the following measures and requirements: x The Lighting Design Plan shall disclose all potential light sources with the types of lighting and their locations. x Typical lighting shall include low mounted, downward casting and shielded lights that do not cause spillover onto adjacent properties and the utilization of motion detection systems where applicable. x No flood lights shall be utilized. x Lighting shall be limited to the areas that would be in operation during nighttime hours. CHAPTER 4: AESTHETICS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 4-19 x Low intensity, indirect light sources shall be encouraged. x On-demand lighting systems shall be encouraged. x Mercury, sodium vapor, and similar intense and bright lights shall not be permitted except where their need is specifically approved and their source of light is restricted. x Generally, light fixtures shall not be located at the periphery of the property and should shut off automatically when the use is not operating. Security lighting visible from the highway shall be motion-sensor activated. x Use “cut-off” fixtures designed to prevent the upward cast of light and avoid unnecessary light pollution where appropriate. x All lighting shall be installed in accordance with the building codes and the approved lighting plan during construction. As the proposed OPSP calls for an increase in development at the site from one-story buildings to more visible four- to ten-story buildings, daytime glare would increase if reflective materials were used, which could adversely affect views by distant land uses, such as motorists traveling along US 101 looking towards the OPSP site to views of the San Francisco Bay, and the San Bruno Mountains. The building design within the OPSP could incorporate a mixture of materials including concrete, metals, composite, brick, terracotta, stove, wood, stucco and/or various types of glass. Buildings in the OPSP area would comply with the guidelines in the Design Element of the East of 101 Area Plan, including those related to building design, specifically Guidelines DE-41 and DE-42. Mitigation Measure Vis-2b: Glare Reduction. In order to reduce sources of daytime glare created by reflective building materials, the applicant shall specify exterior building materials for all proposed structures constructed for the Phase I Project and each subsequent phase of development under the OPSP, including the following: x Exterior building materials shall include the use of textured or other non- reflective exterior surfaces and non-reflective glass types, including double glazed and non-reflective vision glass. x These materials shall be chosen for their non-reflective characteristics and their ability to reduce daytime glare. All exterior glass must meet the specifications of all applicable codes for non-reflective glass and would therefore reduce daytime glare emanating from the OPSP area. Since development under the OPSP would consist of development and lighting treatments typical of the existing commercial/industrial urban settings and would incorporate standard and tailored lighting measures to address undue lighting on adjacent areas and glare off the building as specified in Mitigation Measures Vis-2a and Vis-2b, it would not result in new sources of substantial adverse light or glare. The impact would be reduced to less-than-significant. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 4-20 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT CUMULATIVE AESTHETIC IMPACTS The East of 101 area in South San Francisco is the geographic context for cumulative assessment of visual quality and aesthetics. This area is a historically industrial area transitioning to high technology office/R&D uses as reflected in this and other foreseeable projects in the area. These projects largely involve replacement of older facilities and/or vacant sites and include landscaping and pedestrian improvements to current City standards. All future development that could occur in the vicinity of the OPSP would be required to adhere to established restrictions, guidelines, standards, policies, and criteria that address building appearance, height, bulk, and configuration. Given the current condition of the East of 101 area and the highly designed developments in the foreseeable and anticipated future, as well as mitigation included in this OPSP to reduce contributions to light and glare impacts, the cumulative aesthetic impacts would be less than significant. OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 5-1 5 AGRICULTURAL, FOREST AND MINERAL RESOURCES INTRODUCTION This chapter of the Draft EIR contains discussion regarding the CEQA topic areas of Agricultural, Forest and Mineral Resources. Only limited analysis and discussion for these topic areas is required to make significance determinations due to the nature and specifics of the OPSP site, including the Phase I Project site. . AGRICULTURAL AND FOREST RESOURCES Under the CEQA Guidelines, Appendix G – Environmental Checklist Form, development of the OPSP area as proposed would have a significant environmental impact if it were to result in: 1.Conversion of Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland) as shown on maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non-agricultural use; 2.A conflict with existing zoning for agricultural use, or a Williamson Act contract; or 3.A conflict with existing zoning for, or cause rezoning of, forest land (as defined in Public Resources Code section 12220(g)), timberland (as defined by Public Resources Code section 4526), or timberland zoned Timberland Production (as defined by Government Code section 51104(g)). 4.The loss of forest land or conversion of forest land to no-forest land. 5.Changes in the existing environment which, due to their location or nature, could result in conversion of Farmland to non-agricultural use or conversion of forest land to non-forest use. The OPSP site is located in an urbanized area and includes land that is currently developed with light industrial/office buildings and land that is a closed landfill. No portion of the site has been zoned for agricultural use, forest land, timberland, or Timber Production. No portion of the site currently supports agricultural operations or operates under a Williamson Act contract. There are currently no agricultural operations in the immediate vicinity of the OPSP site, and no Prime Farmland, Unique Farmland, or Farmland of Statewide Importance has been identified on or in the vicinity of the OPSP area. No portion of the site currently contains any forest land for forest uses. There would be no impact related to agricultural and forest resources. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 5-2 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT MINERAL RESOURCES Under the CEQA Guidelines, Appendix G – Environmental Checklist Form, development of the OPSP site as proposed would have a significant environmental impact if it were to result in: 1.Loss of availability of a known mineral resource that would be of future value to the region and the residents of the state; or. 2.Loss of availability of a locally important mineral resource recovery site delineated on a local general plan, specific plan or other land use plan. There are no known mineral resources located at the OPSP area, and no locally important mineral resource recovery site located at the OPSP area or in the vicinity. The OPSP area has not been delineated as a locally important mineral recovery site on the City of South San Francisco General Plan, on any specific plan, or on any other land use plan. Therefore, the proposed development of the OPSP site would not result in the loss of availability of any known mineral resources or the loss of availability of any locally important mineral resource recovery site (no impact). OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 6-1 6 AIR QUALITY INTRODUCTION This analysis evaluates the air quality impacts of the OPSP, including the Phase I Project . The impacts associated with implementation of the OPSP were evaluated in terms of construction and operational impacts to air quality. The primary focus of the air quality analysis was to evaluate future OPSP-related emissions on regional air quality, as well as existing sources of air pollution near the areas subject to the proposed zoning modifications that could affect new sensitive receptors. This analysis was conducted following guidance provided by the Bay Area Air Quality Management District (BAAQMD) 1. SETTING South San Francisco enjoys generally good air quality due largely to the presence of the San Bruno Gap, a break in the Santa Cruz Mountains that allows onshore winds with cool Pacific air to flow easily into San Francisco Bay and quickly disperse air pollutants. As a result, winds are usually from the west. There are periods in fall and winter where winds tend to flow from easterly or southerly directions. Within South San Francisco, certain areas of the city are more likely to result in elevated air pollutant exposure for residents and workers. These areas include the U.S. Highway 101, Interstate 280, and El Camino Real corridors, which experience relatively high pollutant concentrations due to heavy traffic volumes, particularly during peak periods. Winds blowing out of the south and southeast expose the city to emissions from the San Francisco International Airport and the industrial areas that are east of US Highway 101. REGULATORY AIR QUALITY SETTING South San Francisco is located within the nine county San Francisco Bay Area Air Basin. The Bay Area Air Quality Management District (BAAQMD) monitors air quality in the basin through a regional network of air pollution monitoring stations to determine if the national and State standards for criteria air pollutants and emission limits of toxic air contaminants are being achieved. The Federal and California Clean Air Acts have established ambient air quality standards for different pollutants. The national ambient air quality standards (NAAQS) were established by the Federal Clean Air Act of 1970 (amended in 1977 and 1990) for six "criteria" pollutants. These criteria pollutants now include carbon monoxide (CO), ozone (O3), nitrogen dioxide (NO2), particulate matter with a diameter less than 10 microns (PM10), sulfur dioxide (SO2), and lead (Pb). In 1997, EPA added fine particulate matter or PM2.5 as a criteria pollutant. The air pollutants that standards have been established for are considered the most prevalent air pollutants that are known to be hazardous to human health. 1 BAAQMD CEQA Guidelines for Assessing Air Quality Impacts from Projects and Plans, 1996, revised 1999. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 6-2 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Federal Regulations At the federal level, the United States Environmental Protection Agency (U.S. EPA) administers and enforces air quality regulations. Federal air quality regulations were developed primarily from implementation of the Federal Clean Air Act. If an area does not meet NAAQS over a set period (three years), EPA designates it as a "nonattainment" area for that particular pollutant. EPA requires states that have areas that do not comply with the national standards to prepare and submit air quality plans showing how the standards would be met. If the states cannot show how the standards would be met, then they must show progress toward meeting the standards. These plans are referred to as the State Implementation Plan (SIP). Under severe cases, EPA may impose a federal plan to make progress in meeting the federal standards. EPA also has programs for identifying and regulating hazardous air pollutants. The Clean Air Act requires EPA to set standards for these pollutants and sharply reduce emissions of controlled chemicals. Industries were classified as major sources if they emitted certain amounts of hazardous air pollutants. The San Francisco Bay Area Air Basin is subject to air quality planning programs required by the federal Clean Air Act (CAA) (1977, last amended in 1990, 42 United States Code [USC] 7401 et seq.) to address ozone air pollution. The CAA requires that regional planning and air pollution control agencies prepare a regional Air Quality Plan to outline the measures by which both stationary and mobile sources of pollutants can be controlled in order to achieve all standards within the deadlines specified in the Clean Air Act. State Regulations The California Clean Air Act of 1988, amended in 1992, outlines a program for areas in the State to attain the California Ambient Air Quality Standards (CAAQS) by the earliest practical date. The California Air Resources Board (CARB) is the state air pollution control agency and is a part of the California Environmental Protection Agency. The California Clean Air Act set more stringent air quality standards for all of the pollutants covered under national standards, and additionally regulates levels of vinyl chloride, hydrogen sulfide, sulfates, and visibility-reducing particulates. If an area does not meet CAAQS, CARB designates the area as a nonattainment area. The San Francisco Bay Area Air Basin currently does not meet the CAAQS for ozone, PM10 and PM2.5. CARB requires regions that do not meet CAAQS for ozone to submit Clean Air Plans that describe measures to attain the standard or show progress toward attainment. CARB regulates the amount of air pollutants that can be emitted by new motor vehicles sold in California. Motor vehicle emissions standards in California have always been more stringent than federal standards since they were first imposed in 1961. CARB has also developed Inspection and Maintenance (I/M) and "Smog Check" programs with the California Bureau of Automotive Repair. Inspection programs for trucks and buses have also been implemented. CARB also has authority to set standards for fuel sold in California. Bay Area Air Quality Management District The Bay Area Air Quality Management District (BAAQMD) is primarily responsible for assuring that the National and State ambient air quality standards are attained and maintained in the Bay Area. BAAQMD is also responsible for adopting and enforcing rules and regulations concerning air pollutant sources, issuing permits for stationary sources of air pollutants, inspecting stationary sources of air pollutants, responding to citizen complaints, monitoring ambient air quality and meteorological conditions, awarding grants to reduce motor vehicle emissions, conducting public education campaigns, as well as many other activities. BAAQMD has jurisdiction over much of the nine-county Bay Area counties, including San Mateo County, in which Oyster Point is located. CHAPTER 6: AIR QUALITY OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 6-3 City of South San Francisco The City of South San Francisco’s general plan goals address concerns about air quality, and in June 2010, the BAAQMD adopted their CEQA Guidelines, which provide guidance in addressing impacts on global warming. These planning policies are used during the permitting process to assess if the OPSP, including the Phase I Project, is consistent with the policies and whether they meet the established goals. CRITERIA AIR POLLUTANTS Ambient air quality standards have been established by state and federal environmental agencies for specific air pollutants most pervasive in urban environments. These pollutants are referred to as criteria air pollutants because the standards established for them were developed to meet specific health and welfare criteria set forth in the enabling legislation. The criteria air pollutants emitted by development, traffic and other activities anticipated under the proposed development include ozone (O3), ozone precursors oxides of nitrogen and reactive organic gases (NOx and ROG), carbon monoxide (CO), nitrogen dioxide (NO2), and suspended particulate matter (PM10 and PM2.5). Other criteria pollutants, such as lead (Pb) and sulfur dioxide (SO2), would not be substantially emitted by the proposed development or traffic, and air quality standards for them are being met throughout the Bay Area. Ozone (O3) While O3 serves a beneficial purpose in the upper atmosphere (stratosphere) by reducing ultraviolet radiation potentially harmful to humans, when it reaches elevated concentrations in the lower atmosphere it can be harmful to the human respiratory system and to sensitive species of plants. O3 concentrations build to peak levels during periods of light winds, bright sunshine, and high temperatures. Short-term O3 exposure can reduce lung function in children, make persons susceptible to respiratory infection, and produce symptoms that cause people to seek medical treatment for respiratory distress. Long-term exposure can impair lung defense mechanisms and lead to emphysema and chronic bronchitis. Sensitivity to O3 varies among individuals, but about 20 percent of the population is sensitive to O3, with exercising children being particularly vulnerable. O3 is formed in the atmosphere by a complex series of photochemical reactions that involve “ozone precursors” that are two families of pollutants: oxides of nitrogen (NOx) and reactive organic gases (ROG). NOx and ROG are emitted from a variety of stationary and mobile sources. While NO2, an oxide of nitrogen, is another criteria pollutant itself, ROGs are not in that category, but are included in this discussion as O3 precursors. Carbon Monoxide (CO) Exposure to high concentrations of CO reduces the oxygen-carrying capacity of the blood and can cause dizziness and fatigue, impair central nervous system function, and induce angina in persons with serious heart disease. Primary sources of CO in ambient air are passenger cars, light-duty trucks, and residential wood burning. Emission controls placed on automobiles and the reformulation of vehicle fuels have resulted in a sharp decline in CO levels, especially since 1991. Nitrogen Dioxide (NO2) The major health effect from exposure to high levels of NO2 is the risk of acute and chronic respiratory disease. NO2 is a combustion by-product, but it can also form in the atmosphere by chemical reaction. NO2 is a reddish-brown colored gas often observed during the same conditions that produce high levels of O3 and can affect regional visibility. NO2 is one compound in a group of compounds consisting of oxides of nitrogen (NOx). As described above, NOx is an O3 precursor compound. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 6-4 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Particulate Matter (PM) Respirable particulate matter, PM10, and fine particulate matter, PM2.5, consist of particulate matter that is 10 microns or less in diameter and 2.5 microns or less in diameter, respectively. PM10 and PM2.5 represent fractions of particulate matter that can be inhaled and cause adverse health effects. PM10 and PM2.5 are a health concern, particularly at levels above the Federal and State ambient air quality standards. PM2.5 (including diesel exhaust particles) is thought to have greater effects on health because minute particles are able to penetrate to the deepest parts of the lungs. Scientific studies have suggested links between fine particulate matter and numerous health problems including asthma, bronchitis, acute and chronic respiratory symptoms such as shortness of breath and painful breathing. Children are more susceptible to the health risks of PM2.5 because their immune and respiratory systems are still developing. Very small particles of certain substances (e.g., sulfates and nitrates) can also directly cause lung damage or can contain absorbed gases (e.g., chlorides or ammonium) that may be injurious to health. Particulate matter in the atmosphere results from many kinds of dust- and fume-producing industrial and agricultural operations, fuel combustion, and atmospheric photochemical reactions. Some sources of particulate matter, such as mining and demolition and construction activities, are more local in nature, while others, such as vehicular traffic, have a more regional effect. In addition to health effects, particulates also can damage materials and reduce visibility. Dust comprised of large particles (diameter greater than 10 microns) settles out rapidly and is more easily filtered by human breathing passages. This type of dust is considered more of a soiling nuisance rather than a health hazard. In 1983, CARB replaced the standard for “suspended particulate matter” with a standard for suspended PM10 or “respirable particulate matter.” This standard was set at 50 μg/m3 for a 24-hour average and 30 μg/m3 for an annual average. CARB revised the annual PM10 standard in 2002, pursuant to the Children's Environmental Health Protection Act. The revised PM10 standard is 20 μg/m3 for an annual average. PM2.5 standards were first promulgated by the EPA in 1997, and were recently revised to lower the 24-hour PM2.5 standard to 35 μg/m3 for 24-hour exposures and revoked the annual PM10 standard due to lack of scientific evidence correlating long-term exposures of ambient PM10 with health effects. CARB has adopted an annual average PM2.5 standard, which is set at 12 μg/m3, which is more stringent than the Federal standard of 15 μg/m3. TOXIC AIR CONTAMINANTS Besides the "criteria" air pollutants, there is another group of substances found in ambient air referred to as Hazardous Air Pollutants (HAPs) under the Federal Clean Air Act and Toxic Air Contaminants (TACs) under the California Clean Air Act. These contaminants tend to be localized and are found in relatively low concentrations in ambient air. However, they can result in adverse chronic health effects if exposure to low concentrations occurs for long periods. They are regulated at the local, state, and federal level. TACs are a broad class of compounds known to cause morbidity or mortality (cancer risk), and include, but are not limited to, the criteria air pollutants listed above. TACs are found in ambient air, especially in urban areas, and are caused by industry, agriculture, fuel combustion, and commercial operations (e.g., dry cleaners). TACs are typically found in low concentrations, even near their source (e.g., benzene near a freeway). Because chronic exposure can result in adverse health effects, TACs are regulated at the regional, state, and federal level. Diesel exhaust is the predominant TAC in urban air, and is estimated to represent about two-thirds of the cancer risk from TACs (based on the statewide average). According to CARB, diesel exhaust is a complex mixture of gases, vapors and fine particles. This complexity makes the evaluation of health effects of diesel exhaust a complex scientific issue. Some chemicals in diesel exhaust, such as benzene CHAPTER 6: AIR QUALITY OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 6-5 and formaldehyde, have been previously identified as TACs by ARB, and are listed as carcinogens either under State Proposition 65 or under the Federal Hazardous Air Pollutants programs. CARB reports that recent air pollution studies have shown an association that diesel exhaust and other cancer-causing toxic air contaminants emitted from vehicles are responsible for much of the overall cancer risk from TACs in California. Particulate matter emitted from diesel-fueled engines (diesel particulate matter [DPM]) was found to comprise much of that risk. In August, 1998, CARB formally identified DPM as a TAC. Diesel particulate matter is of particular concern, since it can be distributed over large regions, thus leading to widespread public exposure. The particles emitted by diesel engines are coated with chemicals, many of which have been identified by EPA as hazardous air pollutants, and by CARB as TACs. Diesel engines emit particulate matter at a rate about 20 times greater than comparable gasoline engines. The vast majority of diesel exhaust particles (over 90 percent) consist of PM2.5, which are the particles that can be inhaled deep into the lung. Like other particles of this size, a portion will eventually become trapped within the lung, possibly leading to adverse health effects. While the gaseous portion of diesel exhaust also contains TACs, CARB’s 1998 action was specific to DPM, which accounts for much of the cancer-causing potential from diesel exhaust. California has adopted a comprehensive diesel risk reduction program to reduce DPM emissions 85 percent by 2020. The U.S. EPA and CARB adopted low sulfur diesel fuel standards in 2006 that reduce diesel particulate matter substantially. In cooler weather, smoke from residential wood combustion can be a source of TACs. Localized high TAC concentrations can result when cold stagnant air traps smoke near the ground and, with no wind, the pollution can persist for many hours, especially in sheltered valleys during winter. Wood smoke also contains a significant amount of PM10 and PM2.5. Wood smoke is an irritant, and is implicated in worsening asthma and other chronic lung problems. ODORS Objectionable odors may be associated with a variety of pollutants. Common sources of odors include wastewater treatment plants, landfills, composting facilities, refineries and chemical plants. Odors rarely have direct health impacts, but they can be very unpleasant and can lead concern over possible health effects among the public. Each year the Air District receives thousands of citizen complaints about objectionable odors.2 The Phase I Project includes disturbance of the landfill and relocation of landfill materials. The following is a list of general compound categories that could be present in a typical landfill and can cause odors. x Reduced sulfur compounds have low odor detection threshold levels and offensive characteristics such as those of rotten eggs or other rotting materials. x Aldehydes and Amines also have low odor detection threshold levels and pungent and offensive characteristics such as those of old sweaty socks or dead fish. x Ketones and alcohols have low to moderate odor detection levels are generally not offensive and can result in a sweet odor. x Volatile and semi-volatile hydrocarbon compounds have moderate to high odor detection threshold levels and can be generally classified as a chemical/solvent or gasoline (aromatic)/diesel-like odor. x Chlorinate organics have moderate to high odor detection threshold levels and are generally sweet or chlorine-like in nature. 2 BAAQMD, BAAQMD CEQA Guidelines, December 2009, as amended. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 6-6 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Odor compounds can have significantly different characteristics and odor detection thresholds, with a low threshold indicating they are discernable at lower concentrations. In general, reduced sulfur compounds and certain amines and aldehydes have low thresholds and odors that are considered objectionable. Volatile and semi-volatile hydrocarbons and chlorinate organics have distinctive odors; however the odor threshold concentrations are relatively high. Some compounds such as ketones and alcohols have moderate to low odor thresholds, however their odors are sweet and generally not objectionable. Because of the innate variation of materials within a landfill, it is difficult to predict the extent and intensity of potential odors. NATIONAL AND STATE AMBIENT AIR QUALITY STANDARDS The CAA and CCAA promulgate, respectively, national and state ambient air quality standards for carbon monoxide (CO), ozone (O3), nitrogen dioxide (NO2), particulate matter 10 microns or less in diameter (PM10), and particulate matter 2.5 microns or less in diameter (PM2.5).3 Ambient standards specify the concentration of pollutants to which the public may be exposed without adverse health effects. Individuals vary widely in their sensitivity to air pollutants, and standards are set to protect more pollution-sensitive populations (e.g., children and the elderly). National and state standards are reviewed and updated periodically based on new health studies. California ambient standards tend to be at least as protective as national ambient standards, and are often more stringent. National and California ambient air quality standards are shown in Table 6.1, below. For planning purposes, regions like the San Francisco Bay Area Air Basin are given an air quality status designation by the federal and state regulatory agencies. Areas with monitored pollutant concentrations that are lower than ambient air quality standards are designated “attainment” on a pollutant-by-pollutant basis. When monitored concentrations exceed ambient standards within an air basin, it is designated “nonattainment” for that pollutant. U.S. EPA designates areas as “unclassified” when insufficient data are available to determine the attainment status; however, these areas are typically considered to be in attainment of the standard.

CHAPTER 6: AIR QUALITY OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 6-7 EXISTING AIR QUALITY Air quality in the region is controlled by the rate of pollutant emissions and meteorological conditions. Meteorological conditions such as wind speed, atmospheric stability, and mixing height may all affect the atmosphere’s ability to mix and disperse pollutants. Long-term variations in air quality typically result from changes in air pollutant emissions, while frequent, short-term variations result from changes in atmospheric conditions. The San Francisco Bay Area is considered to be one of the cleanest metropolitan areas in the country with respect to air quality. BAAQMD monitors air quality conditions at more than 30 locations throughout the Bay Area. While no monitoring station is located in South San Francisco, the monitoring sites closest to the OPSP site are located in San Francisco and Redwood City. Monitoring station measurements indicate that air quality in the vicinity of South San Francisco performs well against State standards for criteria air pollutants. No violations of the State standard for ozone occurred between 2007 and 2009. Table 6.2 summarizes exceedances of the state and federal standards at the San Francisco monitoring site and Bay Area-wide.

PM10 monitoring was discontinued at Redwood City on June 30, 2008 In 2006, the PM2.5 standard was changed from 65 μg/m3 to 35 μg/m3 Source: Bay Area Air Quality Management District Air Pollution Summaries (http://www.baaqmd.gov/pio/aq_summaries/index.htm) In San Francisco, the Years 2007 through 2009 monitoring data indicate that the air pollutant levels met all state ambient air quality standards except those for particulate matter. There were two days that 24-hour PM10 state standards were exceeded and 6 days that the PM2.5 standards were exceeded. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 6-8 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Table 6.2 shows that air quality as a result of exceedances of O3 and PM2.5 and PM10 standards are problematic in the San Francisco Bay Area. In recent years, the State O3 standards have been exceeded at least somewhere in the Bay Area on 4 to 20 days per year. Because the San Francisco station does not lie downwind of major air pollution sources, O3 standards have not been exceeded in the last 3 years at this location. On the other hand, a station like Concord that lies downwind has exceeded standards on 2 to 14 days per year. Ozone levels in the Bay Area exceeded the federal standard on one day in 2007, and 12 days in 2006 and 2008. PM10 is just as problematic in the Bay Area, where exceedances of state standards are estimated at over 15 days per year. However, the federal PM10 standard has not been exceeded. In 2006, U.S. EPA reduced the 24-hour PM2.5 standard to 35 micrograms per cubic meter. Statistics on the number of days exceeding this standard have only been kept since 2006. The Bay Area has exceeded this standard on 10 to 14 sampling days per year. Continuous monitoring of PM2.5 monitoring in San Francisco shows there were 6 days in 2007 through 2009 where the concentrations were above the standards. Standards for CO and NO2, or any other criteria air pollutant, are not exceeded anywhere in the Bay Area. ATTAINMENT STATUS Areas that do not violate ambient air quality standards are considered to have attained the standard. Violations of ambient air quality standards are based on air pollutant monitoring data and are judged for each air pollutant. The attainment status for the area is summarized in Table 6.3, below. The Bay Area as a whole does not meet state or federal ambient air quality standards for ground level ozone and State standards for PM10 and PM2.5. Table 6.3: Regional Attainment Status PollutantFederal StatusState Status Ozone (O3) – 1-Hour StandardNo DesignationSerious Nonattainment Ozone (O3) – 8-Hour StandardMarginal NonattainmentNonattainment Respirable Particulate Matter (PM10)UnclassifiedNonattainment Fine Particulate Matter (PM2.5)NonattainmentNonattainment Carbon Monoxide (CO)Attainment/UnclassifiedAttainment Nitrogen Dioxide (NO2 Unclassified Attainment Sulfur Dioxide (SO2)Attainment Attainment Sulfates No Designation Attainment Lead No Designation Attainment Hydrogen Sulfide No Designation Unclassified Visibility Reducing Particles No Designation Unclassified Source: Bay Area Air Quality Management District. California Air Resource Board CHAPTER 6: AIR QUALITY OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 6-9 Under the Federal CAA, the U.S. EPA has classified the region as marginally nonattainment for the 1997 8-hour ozone standard. U.S. EPA required the region to attain the standard by 2007. The U.S. EPA determined that the Bay Area has met this standard, but a formal redesignation request and maintenance plan would have to be submitted before formal redesignation could be made. In May 2008, U.S. EPA lowered the 8-hour ozone standard from 0.08 to 0.075 ppm. The USEPA was poised to promulgate nonattainment designations under the 2008 ozone NAAQS in December 2009, which would have included the Bay Area. These nonattainment designations would have become effective by March 12, 2010. However, in January, 2010, the USEPA announced delay of the final designations for the 2008 NAAQS until March 12, 2011, to allow adequate time for reconsideration and possible revision of the 2008 NAAQS. The range of standards under consideration would be a significant change, which would undoubtedly result in a nonattainment designation for the Bay Area and much of California. The Bay Area has met the CO standards for over a decade, and is classified attainment maintenance by the U.S. EPA. The U.S. EPA grades the region unclassified for all other air pollutants, which include PM10 and PM2.5. In December 2008, U.S. EPA designated the entire Bay Area as nonattainment for the federal 24-hour PM2.5 standard. PM2.5 monitoring data showed violations at the Vallejo and San Jose monitoring stations. The Bay Area will have until 2015 to attain the standards, although U.S. EPA could grant extensions to 2020. At the State level, the region is considered serious non-attainment for ground level O3 and non- attainment for PM10 and PM2.5. California ambient air quality standards are more stringent than the national ambient air quality standards. The region is required to adopt plans on a triennial basis that show progress towards meeting the State O3 standard. The Bay Area is also considered nonattainment for PM10 and PM2.5 standards. The area is considered attainment or unclassified for all other pollutants. REGIONAL AIR QUALITY PLANS The BAAQMD and other agencies prepare clean air plans in response to the State and federal Clean Air Acts. The City of South San Francisco also includes General Plan policies that encourage development that reduces air quality impacts. In addition, the BAAQMD has developed CEQA Guidelines to assist local agencies in evaluating and mitigating air quality impacts. 4 2001 Ozone Attainment Plan Addressing the National Standards The BAAQMD, the Metropolitan Transportation Commission (MTC), and the Association of Bay Area Governments (ABAG) prepared the Bay Area 2001 Ozone Attainment Plan. This plan is a proposed revision to the Bay Area’s part of the State Implementation Plan (SIP) to achieve the NAAQS for the 1- hour ozone standard. The plan was prepared in response to U.S. EPA's partial approval and partial disapproval of the Bay Area's 1999 Ozone Attainment Plan. Although U.S. EPA revoked the 1-hour NAAQS, commitments made in that plan along with emissions budgets remain valid until the region develops an attainment demonstration/maintenance plan for the 8-hour NAAQS for ozone. The U.S. EPA has already determined that the region met the 1997 8-hour ozone standard. However, the region will be required to submit a maintenance plan and demonstration of attainment with a request for redesignation to U.S. EPA prior to be formally redesignated. BAAQMD will likely not act on this submittal for a few years. In addition, the U.S. EPA’s new, slightly more stringent, 8-hour standard was recently established. The U.S. EPA will be making new attainment designations based on that standard in about 3 years and eventually revoking the older standard. 4 Bay Area Air Quality Management District California Environmental Quality Act Air Quality Guidelines, June 2010 DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 6-10 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT 1991 Clean Air Plan and Subsequent Updates Addressing the State Standards In 1991, the BAAQMD, MTC and ABAG prepared the Bay Area 1991 Clean Air Plan or CAP. This air quality plan addresses the California Clean Air Act. Updates are developed approximately every three years. The plans were meant to demonstrate progress toward meeting the more stringent 1-hour ozone CAAQS. The latest update to the plan, which was adopted in September 2010, is called the Bay Area 2010 Clean Air Plan. The plan includes the following: x Updates the recent Bay Area 2005 Ozone Strategy in accordance with the requirements of the California Clean Air Act to implement “all feasible measures” to reduce ozone; x Provide a control strategy to reduce ozone, particulate matter (PM), TACs, and greenhouse gases in a single, integrated plan; x Review progress in improving air quality in recent years; and x Establish emission control measures to be adopted or implemented in the 2010-2012 timeframe. PM10 and PM2.5 Plans BAAQMD has found that the primary constituents of elevated PM2.5 and PM10 are secondary ammonium nitrate and wood smoke. Secondary ammonium nitrate forms in the atmosphere as a result primarily of fossil fuel combustion (e.g., motor vehicles). The clean air planning efforts for ozone will also reduce PM10 and PM2.5, since a substantial amount of this air pollutant comes from combustion emissions such as vehicle exhaust. BAAQMD adopts and enforces rules to reduce particulate matter emissions and develops public outreach programs to educate the public to reduce PM10 and PM2.5 emissions (e.g., Spare the Air Program). SB 656 requires further action by CARB and air districts to reduce public exposure to PM10 and PM2.5. Efforts identified by BAAQMD in response to SB 656 are primarily targeting reductions in wood smoke emissions and adoption of new rules to further reduce NOx and particulate matter from internal combustion engines and reduce particulate matter from commercial charbroiling activities. BAAQMD recently adopted a rule addressing residential wood burning. The rule restricts operation of any indoor or outdoor fireplace, fire pit, wood or pellet stove, masonry heater or fireplace insert on specific days during the winter when air quality conditions are forecasted to exceed the NAAQS for PM2.5. The proposed rule also limits excess visible emissions from wood burning devices and requires clean burning technology for wood burning devices sold (or resold) or installed in the Bay Area. Controls on ozone precursor emissions that include NOx and ROG would reduce particulate matter concentrations in winter. NOx emissions contribute to ammonium nitrate formation that resides in the atmosphere as particulate matter. The Bay Area experiences the highest PM10 and PM2.5 in winter, when wood smoke and ammonium nitrate contributions to particulate matter are highest. Because U.S. EPA designated the Bay Area nonattainment for the 24-hour PM2.5 standard, CARB and BAAQMD will have to develop a plan for meeting the standard by December 2014. The plan must be submitted to U.S. EPA by December 2012. Statewide, CARB has taken recent actions at reducing PM2.5 from diesel trucks and construction equipment. On June 2, 2010, the Air District adopted updated thresholds and the BAAQMD CEQA Guidelines in support of the new Clean Air Plan. The CEQA Guidelines Update revised significance thresholds, assessment methodologies, and mitigation strategies for criteria pollutants, air toxics, odors, and greenhouse gas emissions. However, it is BAAQMD policy that these updated thresholds would not apply to projects for which a Notice of Preparation (NOP) was published prior to the effective date of June 2, 2010. CHAPTER 6: AIR QUALITY OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 6-11 City of South San Francisco General Plan The Open Space and Conservation Element of the City of South San Francisco General Plan addresses air quality and includes the following Policies specifically to air quality in the South San Francisco area: x 7.3-G-1 Continue to work toward improving air quality and meeting all national and State ambient air quality standards and by reducing the generation of air pollutants both from stationary and mobile sources, where feasible. x 7.3-G-2 Encourage land use and transportation strategies that promote use of alternatives to the automobile for transportation, including bicycling, bus transit, and carpooling. x 7.3-G-3 Minimize conflicts between sensitive receptors and emissions generators by distancing them from one another. The Transportation element of the General Plan contains the following Policies which indirectly apply to air quality in the South San Francisco area: x 4.4-G-1 Promote local and regional public transit serving South San Francisco. x 4.4-G-2 Explore mechanisms to integrate various forms of transit. o 4.4-I-4 - Encourage SamTrans to increase the shuttle or bus-service to East of 101 area to better serve the area’s growing employment base. o 4.4-I-5 -As part of any revisions to the Oyster Point Marina Specific Plan, explore the feasibility of providing or reserving site for a ferry terminal. SENSITIVE RECEPTORS "Sensitive receptors" are defined as facilities where sensitive population groups, such as children, the elderly, the acutely ill and the chronically ill, are likely to be located. These land uses include residences, schools, playgrounds, childcare centers, retirement homes, convalescent homes, hospitals and medical clinics. The recreation fields located in the center of the Phase I Project development area is the only potentially “sensitive” receptor in the primarily office/commercial uses proposed in the OPSP. BUFFERS FROM SOURCES OF AIR POLLUTION AND ODORS The BAAQMD and CARB recommend that communities include buffers between sensitive receptors and sources of air toxic contaminant emissions and odors. In April, 2005, CARB released the final version of the Air Quality and Land Use Handbook, which is intended to encourage local land use agencies to consider the risks from air pollution prior to making decisions that approve the siting of new sensitive receptors near sources of air pollution. Unlike industrial or stationary sources of air pollution, siting of new sensitive receptors does not require air quality permits, but could create human health problems. The primary purpose of the CARB document is to highlight the potential health impacts associated with proximity to common air pollution sources, so that those issues are considered in the planning process. CARB makes recommendations regarding the siting of new sensitive land uses near freeways, truck distribution centers, dry cleaners, gasoline dispensing stations, and other air pollution sources. These “advisory” recommendations are based primarily on modeling information for studies conducted throughout the state, and may not be entirely reflective of conditions in Oyster Point. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 6-12 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT CARB-recommended setback distances that would apply to Oyster Point are summarized in Table 6.4, below. Table 6.4: Applicable Buffers Between Air Pollution Sources and Sensitive Receptors Source Recommended Setback Comments Truck Distribution Centers Up to 1,000 feet Setback distance is dependent on volumes and types of trucks and their equipment. As with freeways, emission rates will decrease substantially in the future Siting of new sensitive land uses within these recommended distances may be appropriate due to site- specific conditions (e.g., source strength or meteorology), but should only be done after site-specific studies are conducted to identify the actual health risks. CARB acknowledges that land use agencies have to balance other siting considerations such as housing and transportation needs, economic development priorities and other quality of life issues. Buffers should be considered with existing and proposed industrial sources to avoid health, odor and nuisance impacts. IMPACTS AND MITIGATION MEASURES THRESHOLDS OF SIGNIFICANCE Appendix G of the CEQA Guidelines (Environmental Checklist) contains a list of air quality effects that may be considered significant. Implementation of the OPSP would have a significant effect on the environment if it were to: 1.Conflict with or obstruct implementation of the applicable air quality plan; 2.Violate any air quality standard or contribute substantially to an existing or projected air quality violation; 3.Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors); 4.Expose sensitive receptors to substantial pollutant concentrations; or 5.Create objectionable odors affecting a substantial number of people. The CEQA Guidelines state that, where available, the significance criteria established by the applicable air quality management or air pollution control district may be relied upon to make the above determinations. BAAQMD has updated their thresholds and Guidelines on June 2, 2010, but has specifically noted that they would not apply to projects for which a Notice of Preparation (NOP) was published prior to the effective date of June 2, 2010. The NOP for this analysis was published on February 26, 2010, well before this date. Therefore, the OPSP and Phase I Project are compared against thresholds in place at the date of publication of the NOP though comparisons against the updated thresholds are also included for discussion purposes where they are different, as noted in detail under each impact area below. CHAPTER 6: AIR QUALITY OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 6-13 CLEAN AIR PLAN (CAP) POPULATION AND VMT CONSISTENCY Impact Air-1: Conflict with Clean Air Plan Assumptions. Development anticipated as a result of the OPSP would increase employment in an area designed for employment centers served by local and regional transit. However, city-wide, vehicle miles traveled (VMT) was projected to increase at a faster rate than the city’s population, which conflicts with CAP assumptions. This is a significant impact. According to the BAAQMD (in both the 1999 and 2010 BAAQMD Guidelines, though terminology has been updated), the following criteria must be satisfied for a local plan to be determined to be consistent with the CAP and not have a significant air quality impact: 1.The local plan should be consistent with the CAP population and Vehicle Miles Traveled (VMT) or Vehicle Trip assumptions. This is demonstrated if the population growth over the planning period will not exceed the growth rate included in the current CAP and the projected rate of vehicle miles travelled or vehicle trips is less than or equal to the population increase; and 2.The local plan demonstrates reasonable efforts to implement the appropriate Air Quality Plan Transportation Control Measures (TCMs) included in the CAP. In addition, the plans should not lead to development that would lead to violations of ambient air quality standards, which would include projected vehicle miles traveled or vehicle trip increases greater than projected population increases. A key element in air quality planning is to make reasonably accurate projections of future human activities that are related to air pollutant emissions. When the 1991 CAP was updated (Bay Area 2010 Clean Air Plan), it utilized the most recent projections developed by ABAG and vehicle activity projected by the MTC. These projections were based on the most recent projections at the time using land use designators developed by cities and counties through the General Plan process. The City of South San Francisco General Plan was updated in 1999, and so the CAP included the latest General Plan projections. The proposed OPSP is intended to guide development in the Oyster Point Area through 2035. Related amendments to the existing City of South San Francisco General Plan are proposed in order to ensure that the OPSP would be consistent with the General Plan. Implementation of the OPSP would enable the City of South San Francisco to accommodate additional development. The level of non-residential growth assumed for traffic modeling purposes in this Draft EIR is likely higher than will actually occur in the Oyster Point Area based on past trends, regardless of holding capacity. ABAG projections since 2007 are now policy-based in order to encourage city-centered, transit- oriented development in the Bay Area. The most recently released report from ABAG, Projections 2009, would go considerably further in focusing development in areas served by transit, to further a number of inter-related policies regarding GHG reduction, protection of open space, and encouragement of healthy cities. If the OPSP is adopted and implemented, it would be consistent with these projections, and subsequently with the recent CAP recently adopted by BAAQMD. The OPSP promotes the type of development which would tend to reduce adverse regional air quality impacts, by implementing traffic demand measures that reduce per capita vehicle trips. The proposed plan does not include residential growth and the commercial growth in an area already designated for that type of growth would be subject to City required TDM measures that would reduce the trip rate growth. The EIR prepared for the City’s 1999 General Plan identified an inconsistency with the Bay Area Clean Air Plan, related to Vehicle Miles Traveled (VMT). VMT was projected to increase at a faster rate than the City’s population, due in large part to regional traffic growth that would pass through South San DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 6-14 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Francisco, including U.S. 101. The EIR for the General Plan identified the impact as significant and unavoidable. The CAP has been subsequently updated and would include the population and traffic effects of implementing the General Plan. The City of South San Francisco General Plan, updated in 1999, contained policies to reduce emissions from transportation sources. These measures identified in the City of South San Francisco General Plan in section 4.3 the Transportation Element and Section 7.3 the Air Quality Section. Those policies identified as implementation of CAP TCMs in the General Plan are also consistent with TCMs included in the Bay Area 2010 Clean Air Plan. The OPSP would continue to implement the General Plan TCMs. The proposed OPSP is consistent with the 1999 General Plan and the respective EIR. Under the General Plan policies, projects are required to implement a Transportation Demand Management (TDM) program to reduce project trips. A TDM program, along with General Plan policies and Mitigation Measures identified in the Transportation and Circulation chapter of this document (Mitigation Measure Traf-1) would reasonably implement TCMs consistent with those contained in the latest approved Clean Air Plan. The OPSP’s contribution to this particular pre-existing impact would be reduced through implementation of a TDM program. In addition, the proposed OPSP would development employment centers that are served by regional transit. Transit service near the OPSP area includes local bus service and shuttle service to Caltrain and BART. Future ferry service is expected to serve the OPSP site from the on-site ferry terminal currently under construction. Mitigation Measure Traf-1 would reduce impact Air-1 by requiring implementation of a TDM Plan to reduce trips and VMT. The OPSP would not conflict with implementation of the CAP TCMs and would result in a reduced rate of vehicle trip generation due to the implementation of a TDM program and proximity to transit. However, because implementation of a TDM Plan would already be assumed under the General Plan, because the intensity of development and therefore trip generation is greater under the OPSP than under the General Plan designation for the site, and because VMT growth is known to be higher than population growth under the General Plan, the impact related to inconsistency with the Clean Air Plan would be considered significant and unavoidable. EXPOSURE OF SENSITIVE RECEPTORS TO TOXIC AIR CONTAMINANTS (TACS) Impact Air-2: Possible Exposure of Sensitive Receptors to TACs and PM2.5.Development anticipated under the OPSP may expose sensitive receptors to TACs and PM2.5 through development of new non-residential development that may be sources of TACs and PM2.5 and the potential for development of ancillary uses, such as daycare facilities, that would bring sensitive users to the site. Such exposure would represent a potentially significant impact. According to the BAAQMD CEQA Guidelines (both 1999 and 2010), for a plan to have a less-than- significant impact with respect to TACs, buffer zones must be established around existing and proposed land uses that would emit these air pollutants. Buffer zones to avoid TAC impacts must be reflected in local plan policies, land use maps, or implementing ordinances. New stationary sources of TACs would be subject to BAAQMD rules and regulations. BAAQMD Regulation 2, Rule 5 requires that new stationary sources meet emission standards and the BAAQMD would be required to ensure that health risks associated with TAC emissions would be acceptable.5 5 BAAQMD risk policy requires that these sources have a cancer risk of less than 10 in one million, which is the same as BAAQMD’s recommended CEQA threshold. CHAPTER 6: AIR QUALITY OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 6-15 Sources of air pollutant emissions complying with all applicable BAAQMD regulations generally will not be considered to have an individual significant air quality impact. Stationary sources that are exempt from BAAQMD permit requirements due to low emission thresholds would not be considered to have a significant air quality impact. There are potential sources that are not regulated by BAAQMD that could be considered TAC sources. Such sources are identified in Table 6.4. These sources are not likely to be part of the OPSP. As a result, the OPSP would have a less than significant impact. When siting new sensitive receptors, the BAAQMD Guidelines advise that lead agencies examine existing or future proposed sources of TAC and/or PM2.5 emissions that would adversely affect individuals within the planned project. Although the OPSP does not propose new residences, recreation uses could be included in the OPSP area. As a result, the OPSP could place sensitive receptors near an existing truck distribution area. In addition, there are stationary sources of TAC and PM2.5 emissions in the OPSP area. The combination of these sources could result in TAC levels that would be significant for new sensitive receptors. Neither the General Plan nor the OPSP includes policies to require buffers or reduce exposure of existing and future sensitive receptors from existing and future sources of TACs and odors. The Oyster Point area is generally fully commercialized and there is no opportunity to develop buffer zones that would be needed to ensure that exposures are consistent with CARB and BAAQMD guidance (e.g., CARB Air Quality and Land Use Handbook and BAAQMD CEQA Guidelines). There are a limited number of existing industries in Oyster Point area that create air pollution. The OPSP proposes no changes in the types of uses allowed in the area than are currently permitted under existing zoning. While new regulations under the OPSP would allow a somewhat greater intensity of use than currently permitted, new uses would be required to meet higher standards of performance for the release of odors and other potential air quality pollutants and; therefore, the impacts of these new uses should be much less than the impacts of existing businesses that were established without such controls. There is no evidence that these uses would result in TAC or PM2.5 emissions that would create a significant community risk impact (i.e., incremental cancer risk or 10 in one million chances, Hazard of 1.0 or annual PM2.5 concentration of 0.3 μg/m3). Despite the improvements in pollution control requirements, there could be localized effects if sensitive receptors are located close to industrial or commercial uses that may create conflicts. The OPSP does include recreation fields, however, the uses are transient in nature. Users of the fields would not have extended exposures, such that they could be exposed to unhealthy levels of TACs or PM2.5. The OPSP cannot anticipate such localized impacts, but can avoid significant impacts by ensuring that individual projects built under the OPSP do not create these conflicts. The exposure of new sensitive receptors to unhealthy levels of TACs would be a potentially significant impact. Mitigation Measure Air-2: Health Risk Assessment for Proposed Sensitive Receptors. New projects within the OPSP area that would include sensitive receptors (e.g., daycare centers) shall analyze TAC and PM2.5 impacts and include mitigation measures to reduce exposures to less than significant levels. The following measures could be utilized in site planning and building designs to reduce TAC exposure: x New development of sensitive receptors located within OPSP area shall require site specific analysis to determine the level of TAC and PM2.5 exposure. This analysis shall be conducted following procedures outlined by BAAQMD. If the site specific analysis reveal significant exposures, based on BAAQMD guidance, then additional measures listed below shall be required. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 6-16 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT x Where exterior exposures are significant, consider site planning to buffer new sensitive receptors from TAC emissions. Active site uses and building air intakes shall be situated away from TAC sources x Provide tiered plantings of vegetation along the site boundaries closest to TAC sources. Preliminary laboratory studies show that redwood and/or deodar cedar trees can remove some of the fine particulate matter emitted from traffic under low wind speeds. Low wind speeds typically result in the highest particulate matter concentrations. Assessment of health risk for specific projects that come through which will bring sensitive users to the site for long periods each day, such as child daycare facilities, and implementation of appropriate mitigating features as outlined in mitigation measure Air-2 would ensure that resulting TAC and PM2.5 exposures would be below the BAAQMD thresholds and therefore less-than-significant. The potential for health risk related to the construction period is discussed under Construction-Period Impacts. OBJECTIONABLE ODORS Impact Air-3: Possible Exposure of Sensitive Receptors to Operational Odors. Development anticipated under the OPSP may expose sensitive receptors to odors through development of new non-residential development that may be sources of odors near sensitive receptors. Such exposure would represent a less-than-significant impact. Odors are assessed based on the potential of the proposed OPSP to result in odor complaints (in both the 1999 and 2010 BAAQMD Guidelines). This could result by the proposed project creating objectionable odors or placing people near sources of objectionable odors. Due to the commercial nature of the Oyster Point area, odors may be present. Responses to odors are subjective and vary by individual and type of use. Sensitive land uses that include outdoor uses, such as residences and possibly daycare facilities, are likely to be affected most by existing odors. However, such uses are not located in or near the OPSP area such that frequent odor complaints are expected. As a result, the impact would be considered less-than-significant. The potential for odor impacts related to the construction period is discussed under Construction-Period Impacts, below. CONSTRUCTION-RELATED IMPACTS Impact Air-4: Construction Period Dust, Emissions and Odors. Construction of development projects under the OPSP would result in temporary emissions of dust, diesel exhaust and odors that may result in both nuisance and health impacts. Without appropriate measures to control these emissions, these impacts would be considered significant. Construction of development projects under the OPSP would involve demolition, some grading or site preparation, and building erection. Dust would be generated during demolition, grading and construction activities. Most of the dust would result during demolition activities and site preparation. The amount of dust generated would be highly variable, and is dependent on the size of the area disturbed, amount of activity, soil conditions and meteorological conditions. Typical winds during late CHAPTER 6: AIR QUALITY OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 6-17 spring through summer are from the west. Afternoon winds in late spring and summer can be gusty when conditions are dry. Land uses in the surrounding area include residential, office and commercial or retail areas that could be adversely affected by dust generated from construction. In addition, construction dust emissions can contribute to regional PM10 emissions. Although these construction activities would be temporary, they would have the potential to cause both nuisance and health-related air quality impacts. PM10 is the pollutant of greatest concern associated with dust. If uncontrolled, PM10 levels downwind of actively disturbed areas could possibly exceed State standards. In addition, dust fall on adjacent properties could be a nuisance. If uncontrolled, dust generated by grading and construction activities represents a significant impact associated with OPSP- related development. Construction impacts would be a source of exhaust emissions from construction vehicles. Exhaust from construction equipment and associated heavy-duty truck traffic emits diesel particulate matter, which is a known Toxic Air Contaminant. In the new CEQA Guidelines the BAAQMD has developed procedures or guidelines for identifying impacts from temporary construction activities where emissions are transient. These thresholds, however, do not apply to plan level impacts. Construction emissions for the Phase I Project were computed using the URBEMIS2007 model. Construction was assumed to occur over an approximate 3.5-year period (spanning 2012 through 2015) and include demolition of the existing buildings. The URBEMIS2007 model was used to predict construction emissions for construction of the Phase I Project. Construction phases included the following: x Demolition of the existing building on site; x Mass grading, including landfill relocations (including relocation of up to 120,000 cubic yards of material); x Fine site grading of the site; x Trenching was used to address the installation of wet and dry utilities along with paving was assumed to occur at the same time as trenching and also overlap with some grading activities; x Building construction would start when site grading is completed; x Paving would occur at the completion of the building exterior; and x Architectural coatings (e.g., painting) would occur during the final year and one half of building construction. Emissions from construction are shown in Table 6.5. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 6-18 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Table 6.5: Daily Regional Air Pollutant Emissions for Construction of the Phase I Project (Pounds Per Day) Description Reactive Organic Gases Nitrogen Oxides Particulate Matter (PM10)* Fine Particulate Matter (PM2.5) * 2012 10.9 66.7 3.5 3.2 2013 8.6 37.9 2.3 2.1 2014 33.9 17.5 1.0 0.9 2015 35.6 27.9 1.9 1.8 1999 BAAQMD Thresholds No quantitative thresholds 2010 BAAQMD Thresholds 54 54 82 54 * Applies to exhaust emissions only As shown in Table 6.5, emissions of NOx would be anticipated to be over BAAQMD 2010 thresholds. However, these thresholds would not be applicable to this analysis as it was begun prior to adoption of those thresholds. The applicable 1999 thresholds include only the implementation of best management practices and not quantitative thresholds for the construction period. Therefore, no exceedance of any applicable threshold would be identified based upon the projected construction-period emissions. Diesel exhaust in the form of diesel particulate matter or DPM is a TAC. During Phase I Project construction, DPM would be emitted and may affect sensitive receptors. People residing on live- aboard boats would be located about 300 to over 1,000 feet from most construction activities. Some construction activities could be as close as 150 feet. In general, sensitive receptors would be 500 feet or further from the bulk of the construction activity. Impacts of TACs on sensitive receptors are typically evaluated in terms of health risk. In the case of DPM, these impacts are evaluated based on predicted cancer risk, based on a lifetime exposure that is assumed to be 70 years. As described above, construction would occur over about a 4-year period with daily emissions ranging from 1.0 to 2.6 pounds per day of PM10 exhaust. Assuming all of this exhaust is DPM, the emission rate would be relatively low. Given the relatively short period of exposure and the separation distance between sensitive receptors and construction activities, health risks would likely be well below the significance thresholds of 10 excess cancer cases per million or a Hazard Index greater than 1. (These are 1999 and 2010 BAAQMD thresholds, though these thresholds were not generally applied to the construction- period under the 1999 BAAQMD Guidelines). However, the impact would be considered significant if measures to reduce DPM emission are not included during construction (see mitigation measure Air-4, below). Given the age of some buildings in the area, asbestos-containing materials may be present in existing structures that may be demolished as part of development projects constructed under the OPSP. Investigations would be required to identify these materials prior to any construction activities. Demolition activities would require permits from the BAAQMD if removal or disturbance of hazardous materials were to occur. For instance, the handling of asbestos containing materials is subject to BAAQMD Regulation 11 – Hazardous Pollutants, Rule 2 – Asbestos Demolition, Renovation and Manufacturing. Asbestos is a TAC that has been known to cause a number of disabling and fatal diseases such as asbestosis, lung cancer, and mesothelioma. There is no identified safe level of exposure to asbestos; therefore, all exposure to asbestos should be avoided. Project applicants would be required to consult with the BAAQMD’s Enforcement Division prior to handling materials that may contain asbestos. Adherence to this requirement on a project-by-project basis ensures that asbestos- related impacts would be less than significant. The regulation is designed to employ the best available dust mitigation measures in order to reduce and control dust emissions for both onsite workers and the public. CHAPTER 6: AIR QUALITY OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 6-19 Construction activities include disturbance of the landfill and relocation of landfill materials both on- and off-site, temporarily having the potential to cause odors that could affect nearby businesses and people residing on live-aboard boats in the marinas. These odors would be transient and temporary and such activities would be conducted in accordance with current BAAQMD rules and regulations. The applicant has proposed measures to reduce the potential impact of these temporary odors, which have been included as Mitigation Measure Air-4b below. The BAAQMD CEQA Air Quality Guidelines do not identify plan level thresholds that apply to construction. Although construction activities at individual project sites are expected to occur during a relatively short time, the combination of temporary dust from activities and diesel exhaust from construction equipment poses both a health and nuisance impact to nearby receptors. In addition, NOx emissions during grading and soil export would exceed 2010 BAAQMD NOx emission thresholds. This would not have been identified as an NOx exceedance under the 1999 BAAQMD thresholds, which included no quantitative threshold for construction-period emissions but recommended implementation of feasible control measures to determine the impact would be less than significant. As a result, this would be considered a potentially significant impact. Mitigation Measure Air-4a: Implement BAAQMD-Recommended Measures to Control Particulate Matter Emissions during Construction. Measures to reduce diesel particulate matter and PM10 from construction are recommended to ensure that short-term health impacts to nearby sensitive receptors are avoided. Dust (PM10) Control Measures: x Water all active construction areas at least twice daily and more often during windy periods. Active areas adjacent to residences should be kept damp at all times. x Cover all hauling trucks or maintain at least two feet of freeboard. x Pave, apply water at least twice daily, or apply (non-toxic) soil stabilizers on all unpaved access roads, parking areas, and staging areas. x Sweep daily (with water sweepers) all paved access roads, parking areas, and staging areas and sweep streets daily (with water sweepers) if visible soil material is deposited onto the adjacent roads. x Hydroseed or apply (non-toxic) soil stabilizers to inactive construction areas (i.e., previously-graded areas that are inactive for 10 days or more). x Enclose, cover, water twice daily, or apply (non-toxic) soil binders to exposed stockpiles. x Limit traffic speeds on any unpaved roads to 15 mph. x Replant vegetation in disturbed areas as quickly as possible. x Suspend construction activities that cause visible dust plumes to extend beyond the construction site. x Post a publically visible sign(s) with the telephone number and person to contact at the Lead Agency regarding dust complaints. This person shall respond and take corrective action within 48 hours. The Air District’s phone number shall also be visible to ensure compliance with applicable regulations. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 6-20 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Additional Measures to Reduce Diesel Particulate Matter and PM2.5 and other construction emissions: x The developer or contractor shall provide a plan for approval by the City or BAAQMD demonstrating that the heavy-duty (>50 horsepower) off-road vehicles to be used in the construction project, including owned, leased and subcontractor vehicles, will achieve a project wide fleet-average 20 percent NOx reduction and 45 percent particulate reduction compared to the most recent CARB fleet average for the year 2011 x Clear signage at all construction sites will be posted indicating that diesel equipment standing idle for more than five minutes shall be turned off. This would include trucks waiting to deliver or receive soil, aggregate, or other bulk materials. Rotating drum concrete trucks could keep their engines running continuously as long as they were onsite or adjacent to the construction site. x Opacity is an indicator of exhaust particulate emissions from off-road diesel powered equipment. Each project shall ensure that emissions from all construction diesel powered equipment used on the project site do not exceed 40 percent opacity for more than three minutes in any one hour. Any equipment found to exceed 40 percent opacity (or Ringelmann 2.0) shall be repaired immediately x The contractor shall install temporary electrical service whenever possible to avoid the need for independently powered equipment (e.g. compressors). x Properly tune and maintain equipment for low emissions. Mitigation Measure Air-4b: Implement Odor-Control Measures During Refuse Relocation. The following measures shall be implemented during disturbance of the landfill for refuse relocation: x All areas shall remain under foundation layer cover until localized refuse relocation occurs. x Limit the horizontal area of opened foundation layer to at most an acre of horizontal area at any one time per area (an acre for the area being excavated and an acre for the area where trash is being relocated). x Excavation and fill zones shall be covered at the end of each day, either with secured tarping or with the foundation layer of soil. x Additional measures for odor control such as a foam cover or scented misters in active areas and/or covering of the materials in the haul trucks may be considered and implemented based upon actual field conditions. x Post a publically visible sign(s) with a 24-hour contact number for odor complaints. The Air District’s phone number shall also be visible to ensure compliance with applicable regulations. Concerns/complaints related to odor from the work will be evaluated and protocol measures will be amended as necessary. x If 10 or more complaints are logged with BAAQMD within a 90-day period, BAAQMD will have regulatory authority that supersedes this mitigation measure consistent with BAAQMD Regulation 7. CHAPTER 6: AIR QUALITY OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 6-21 With implementation of the fugitive dust, emissions reduction, and odor control measures presented in mitigation measures Air-4a and Air-4b, the air quality impacts associated with grading and new construction to a level of less than significant. This satisfies the 1999 BAAQMD qualitative threshold requiring implementation of feasible control measures during construction. Note that these measures would also reduce total NOx emissions by at least 10 percent; however, they would remain above the 2010 BAAQMD threshold of 54 pounds per day during Phase I Project construction. OPERATIONAL RELATED IMPACTS Impact Air-5: Operational Air Quality Impacts. Operation under the OPSP would result in permanent emissions of ozone precursor pollutants and particulate matter. These impacts would be considered less-than-significant. The OPSP would intensify the land use, and would result in new air pollutant emissions, primarily from automobile use. Future changes to air quality resulting from these automobile trips were predicted using computer models. Emissions were calculated using the URBEMIS2007 model, while predicted CO concentrations were modeled using screening methodologies based on the Caline4 model. The modeling outputs are contained in Appendix B. Regional Air Quality Impacts Emissions from operation of the Phase I Project could cumulatively contribute to air pollutant levels in the region. Since the Bay Area is considered nonattainment for ozone, PM10 and PM2.5, emissions of these pollutants or their precursors could contribute to existing air quality problems. For this reason, BAAQMD has adopted emission-based significance thresholds to measure the significance of a project’s contribution. These thresholds apply to the Phase I Project impacts and not programmatic impacts for the remainder of the OPSP. The project would emit air pollutants that affect air quality in the region. These air pollutants include ROG and NOx that affect ozone levels (and to some degree – particulate levels), PM10 and PM2.5. The proposed project would add new traffic trips, which would lead to increased emissions of air pollutants. Emissions of air pollutants associated with the project were predicted using the URBEMIS2007 model (Version 9.2.4), distributed by the Rimpo Associates (www.urbemis.com) and recommended for use by BAAQMD. This model predicts daily emissions associated with development projects by combining predicted daily traffic activity, associated with the different land use types, with emission factors from the State’s mobile emission factor model (i.e. EMFAC2007). Trip generation rates used in URBEMIS2007 are based on the traffic model outputs discussed in Table 16.19 in Chapter 16: Traffic and Circulation in this EIR. Trip generation estimates take into account the assumption that a moderate TDM program will reduce compared to existing traffic generation rates. The objective of TDM programs is to reduce vehicle trips at commercial/residential developments by incorporating project components such as encouraging increased transit use, carpooling, and providing facilities for bicyclists and pedestrians. South San Francisco has a “menu” of potential TDM programs, each with a specific number of points that relate to the program’s effectiveness. Examples of TDM programs include bicycle racks and lockers, free carpool parking, shuttle services, and on-site amenities. The URBEMIS2007 model also predicts area source emissions associated with the proposed project. Those sources, which include water and space heating, are minor compared to emissions associated with traffic. Default parameters for the San Francisco Bay Area were used in the URBEMIS2007 model such as the temperature, trip types and lengths, and vehicle mix. Since the BAAQMD thresholds are based on DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 6-22 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT average daily emissions, average daily emissions were predicted with the model using the annual emissions and averaging them over a typical year. Phase I Project conditions include about 508,000 square feet of office/research and development buildings and approximately 10,000 square feet of Auxiliary Commercial uses. The traffic study predicts that this phase would add 2,671 two-way daily trips. The Phase I Project was assumed to be completed and fully operational in 2015. Area and mobile emissions associated with the existing uses are reported in Table 6.6. These emissions are compared to the significance thresholds adopted by the BAAQMD. Emissions associated with full build-out of the proposed OPSP in 2035 are also reported in Table 6.6. Existing and Proposed emissions are presented for the OPSP buildout. The difference between proposed OPSP and the emissions associated with existing land uses (projected into the future) are shown as the “Net Increase” in the Table.

This is the latest version of the State’s model used to develop past, existing and projected vehicle emission inventories. The vehicle emission rates are dependent on the age and mix of the vehicle fleet. The model predicts a continuation of decreases in vehicle air pollutant emission rates for future vehicle fleets. These were represented in the modeling. Vehicle emission rates for ROG and NOx are currently decreasing with each year and are predicted to decrease substantially between 2010 and 2020. For instance, NOx emission rates are predicted to decline by 56 percent during that period, due to improvements in vehicle emissions and retirement of older, more polluting, vehicles from the roadways. Emission rates would continue to decline through 2035, when the entire OPSP is expected to be built out. Particulate matter emissions are comprised of vehicle exhaust, tire and brake wear, and the entrainment of dust into the atmosphere from vehicles traveling on paved roadways. The EMFAC2007 portion of CHAPTER 6: AIR QUALITY OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 6-23 the URBEMIS2007 model provides emission rates of PM10 and PM2.5 from exhaust and tire and brake wear. URBEMIS2007 includes emission of entrained roadway dust based on the type of roadways that are primarily traveled. For this assessment, all travel was considered to occur on paved arterial or collector roadways. The contribution of tire and brake wear is small compared to the other PM emission processes. Gasoline powered engines have small rates of particulate matter emissions compared with diesel-powered vehicles. Since much of the traffic fleet would be made up of light-duty gasoline-powered vehicles, a large portion of the PM10 emissions would be from entrainment of roadway dust from vehicle travel. The URBEMIS2007 default silt loading values were changed to reflect values that CARB uses for calculating paved roadway dust emissions for the average vehicle traveling on arterial and collector roadways. Daily air emissions predicted with full build-out of the proposed Phase I Project are reported in Table 6.6 above and compared against BAAQMD thresholds. The project-level emissions would be below the significance thresholds established by BAAQMD (both the 1999 and 2010 thresholds). As a result, the Phase I Project would have a less-than-significant impact on regional air quality. Emissions for the entire OPSP build-out are shown for informational purposes, as there is no emission-based significance threshold for plan-level impacts. Plan level impacts to air quality, with respect to regional emissions, are evaluated under Impact Air-1 consistent with BAAQMD Guidelines. This impact evaluates the consistency of the OPSP with the clean air plan. However, it should be noted that emissions from the OPSP at full build out would be below the current BAAQMD project level emission thresholds. Carbon Monoxide The OPSP related traffic would increase concentrations of carbon monoxide along roadways serving the Oyster Point area. Carbon monoxide is a localized air pollutant, where the highest concentrations are found very near sources. The major source of carbon monoxide is automobile traffic. Elevated concentrations, therefore, are usually only found near areas of high traffic volume and congestion. The contribution of OPSP related traffic to these levels was predicted following the screening guidance recommended by the BAAQMD. This contribution was added to the background levels. Carbon monoxide concentrations measured over a three year period in San Francisco and Redwood City indicate a maximum concentration of 2.9 parts per million over an 8-hour averaging period. A review of intersection traffic volumes and level of service was conducted to identify intersections with the potential for highest carbon monoxide levels that would be affected by implementation of the OPSP. The intersections with a combination of poor level of service (LOS) and high traffic volumes were evaluated for potential high carbon monoxide levels. The intersections in the Oyster Point area with LOS E or worse that had high traffic volumes were modeled. Future carbon monoxide levels were predicted near these intersections for existing conditions and future “With Project” conditions in place using traffic projections provided in the Section F: Transportation/Traffic, below. Emission factors used were calculated using the EMFAC2007 model, developed by the California Air Resources Board, with default assumptions for San Francisco County during the winter, including a temperature of 40 degrees F. A slow travel speed of 5 miles per hour was used which results in higher emission rates. The screening analysis included the number of through lanes in the intersection configuration with a receptor located at the edge of the roadway. Table 6.7, below, summarizes the highest predicted concentrations. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 6-24 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Table 6.7: Predicted 8-Hour Worst Case Carbon Monoxide Levels (In PPM) As shown in Table 6.7, the modeling indicates that existing 8-hour Carbon Monoxide levels are currently below National and California Ambient Air Quality Standards. The 8-hour carbon monoxide levels with implementation of the OPSP (in 2035) are predicted to remain below ambient air quality standards. This is the result of decreases in emission rates due to newer automobiles with much improved exhaust emission control replacing older vehicles. The decline in carbon monoxide emissions rates began two decades ago. It has been reflected in the monitoring data, which show that a carbon monoxide concentration has not exceeded standard since about 1991. As a result, the impact on local air quality resulting from OPSP implementation is below 1999 and 2010 BAAQMD thresholds and considered to be less than significant. CUMULATIVE IMPACTS Additional analysis to determine cumulative impacts of a project or plan is not necessary. In developing thresholds of significance for air pollutants, BAAQMD considered the emission levels at which a project’s individual emissions would be cumulatively considerable. Because the Phase I Project emissions during construction and operation would not exceed these thresholds, they would not have a cumulatively considerable effect. Impacts to local air quality, which were found to be less than significant, have already included cumulative traffic conditions. The analysis of construction impacts identified as mitigation “Best Management Practices” to minimize localized emissions of PM10 and diesel exhaust. However, Implementation of the OPSP was considered to conflict with the regional Clean Air Plan, because it could increase VMT to a higher level than included in the regional projections used to develop the latest Clean Air Plan. This was identified as a significant and unavoidable impact.

OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 7-1 7 BIOLOGICAL RESOURCES INTRODUCTION This chapter is based on the Biological Resources Report prepared by H. T. Harvey & Associates for this analysis, dated September 21, 2010, the full text of which is included as Appendix C. Site visits were conducted for this analysis on November 11, 2009, December 12, 2009, May 5, 2010 and September 17, 2010. The Biological Resources Report was also based on review of the following documents: x California Department of Fish and Game’s Natural Diversity Database (CNDDB 2010); x Candlestick Point/Hunters Point Shipyard Project Biological Technical Report (PBS&J 2009); x South San Francisco Ferry Terminal Draft Environmental Impact Report (San Francisco Bay Area Water Transit Authority 2005); and x other technical databases and publications on special-status species in the vicinity. This chapter provides information on biological resources in the OPSP area, including the Phase I Project site. A discussion of federal, state, and local laws, policies, and regulations that influence the protection of such biological resources is presented. The chapter identifies impacts on biological resources that may result from site grading and construction, and habitat conversion, reduction or elimination and identifies mitigation measures to avoid, minimize, or compensate for potential significant impacts to biological resources. ENVIRONMENTAL SETTING Biotic Habitats Seven biotic habitats/land use types occur on the OPSP area: developed/landscaped, California annual grassland/coyote brush scrub, armored rock levee slope, northern coastal salt marsh, ornamental woodland, sandy beach, and open water. These habitats are described in detail below, and their distribution both within the OPSP area and, for certain sensitive habitats, in adjacent areas is shown on Figure 7.1.Table 7.1 provides the approximate acreage of each habitat and land use type within the OPSP boundary.

CHAPTER 7: BIOLOGICAL RESOURCES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 7-5 Table 7.1: Biotic Habitat/Land Use Acreages within the Boundaries of the OPSP Area Biotic Habitat/Land Use Total Area (ac) Developed/Landscaped 57.16 California Annual Grassland/Coyote Brush Scrub 18.90 Armored Rock Levee Slope 1.81 Northern Coastal Salt Marsh 2.47 Ornamental Woodland 0.57 Sandy Beach 0.38 Open Water, Marine 0.27 Total 81.56 Developed/Landscaped The OPSP area includes approximately 57.16 ac of developed and landscaped land uses comprised of hardscaped roads, buildings, parking lot surfaces, paved trail surfaces, ornamental and landscaped areas (typically irrigated with a mulch base), and irrigated turf. The habitat suitability for rare or native vegetation in these areas is very low. All developed areas within the survey area appear to be purposefully and continually maintained, or otherwise are permanently impacted by hardscape and structures. Developed habitats primarily support common, urban-adapted wildlife species, and overall wildlife abundance and diversity are low. Likewise, landscaped habitats are used sparingly by most wildlife species, largely because of the uniform, open nature of most landscaping, and regular disturbances due to landscape maintenance and use. However animals living in adjacent habitats and migratory birds often exploit foraging opportunities offered by landscaped habitats, and dense shrub and tree landscape components may offer sufficient cover for nesting birds and mammals. California Annual Grassland/Coyote Brush Scrub Approximately 18.90 ac of the OPSP area are dominated by California annual grassland/coyote brush scrub. These areas vary in composition based on water availability and soil characteristics. Non-native annual grass species are dominant throughout the annual grassland. Native purple needlegrass, (Nassella pulchra) is becoming establishedsouth of Marina Boulevard near the road along with herbaceous species such as birds-foot trefoil (Lotus corniculatus), flax (Linum sp.), and blue eyed grass (Sisyrinchium bellum). However, this patch of native grass is too small to be distinguished as a separate habitat type. Some shrubs such as coyote brush (Baccharispilularis), toyon (Heteromeles arbutifolia), and big saltbush (Atriplex lentiformis) have become established along the slopes above the estuarine canal south of Marina Boulevard. The grassland and scrubby habitats within the Project boundaries host a variety of common invertebrates, which in turn provide food for widespread reptiles and for a number of bird and mammal species. A western meadowlark (Sturnella neglecta) and a Say’s phoebe (Sayornis saya) were observed foraging at the southwestern corner of the OPSP area. Although other grassland-associated species occur in the Project vicinity and may forage in the OPSP area on occasion, this patch of grassland is likely too small to support nesting pairs of these species. Small mammals and mesocarnivores including house mice, striped skunks, and raccoons may forage in these habitats, and several valley pocket gopher (Thomomys bottae) burrows were observed in the grassland in the southwestern corner of the OPSP area. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 7-6 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Armored Rock Levee Slope Armored rock levee slope covers approximately 1.81 ac within the OPSP area and extends downslope from the Project boundary in a number of areas. The rock levees surround the Marina Boulevard peninsula and the OPSP area bordering the water west of Oyster Point Boulevard. This habitat is primarily composed of large rock rip-rap on varying degrees of slope approximately 10-15 ft wide at the edge of the water and tidal flats. Vegetation in this community is only found between the rocks and bordering the top of the slopes. It is dominated by non-native species. North of Marina Boulevard, the rock levee intergrades somewhat with salt marsh species. The rock levee slope west of Oyster Point Boulevard is influenced by landscape plantings, which have been planted along the top edges of the rip-rap. Armored rock levees such as those along the periphery of the OPSP area provide limited wildlife habitat because of their unyielding surfaces, lack of vegetation, and proximity to open marine water, but are nonetheless utilized by several species for foraging or refugia. Rocky shore crab species could shelter in crevices between the rocks, foraging on algae that grow there. Rocky shore-associated birds such as black turnstones (Arenaria melanocephala) have been observed foraging occasionally on the rocks at Oyster Point. The levee slopes also could provide habitat for nuisance species such as Norway rats, black rats (Rattus rattus), and feral cats, which are known to prey upon native wildlife species. Northern Coastal Salt Marsh Approximately 2.47 ac of northern coastal salt marsh occurs in the OPSP area in strips or larger areas surrounding the rock levees and along the estuarine canal South of Marina Boulevard. In some areas, this marsh continues downslope from the Project boundary. These areas are in the intertidal zone, and are influenced daily by rising and falling tides within the bay. In slightly higher elevation areas of the marshes, natives such as saltgrass and spearscale (Atriplex triangularis) occur with ruderal, non-native species such as brass buttons (Cotula coronopifolia). As the elevation decreases these species give way to a mix of native coastal salt marsh and alkaline-adapted species such as pickleweed (Salicornia virginica), sea lavender (Limonium californicum), and marsh jaumea (Jaumea carnosa). Other common plants in the salt marsh include coast gumweed (Grindelia stricta) and red sand spurry (Spergularia rubra). In frequently inundated areas and some marsh channels, stands of cordgrass (Spartina sp.) have been sprayed through control efforts between the 2009 and 2010 site visits. Therefore, much of the emergent tall grass structure typical of the lowest elevation portions of the marsh was missing from the OPSP area. The salt marsh southwest of the Oyster Cove Marina off of Oyster Point Boulevard has accumulated sediment and supports a small but productive tidal wetland community. The vegetation here matches that described above but covers a larger, more continuous area. It also supports a suite of bulrushes (Schoenoplectus sp.), rushes (Juncus sp.), and cattails (Typha sp.), which indicate the influence of freshwater from the adjacent drainage. A large population of cordgrass (Spartina sp.) was observed growing in this marsh during the November 2009 site visit. In May 2010 the cordgrass in this marsh was dead, indicating that it too had been controlled through Spartina control efforts. Salt marsh habitats form unique ecological communities in the San Francisco Bay that support wildlife species adapted to a saline environment and frequent cyclic changes in water levels, as well as several more widely-adapted common species. The mudflats associated with Bay salt marsh habitats provide shelter for burrowing invertebrates and rich foraging habitats for a plethora of wildlife species. Mallards (Anas platyrhynchos) and snowy egrets (Egretta thula) were observed foraging in the tidal channels in the salt marsh habitat along the southwestern portion of the OPSP area, as well as roosting higher up in pickleweed beds, and white-crowned sparrows were seen foraging in the highest edges of these salt marshes. Common bird species that live in adjacent habitats may also forage in the higher CHAPTER 7: BIOLOGICAL RESOURCES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 7-7 portions of these salt marshes on occasion; it is possible that Alameda song sparrows (Melospiza melodia pusillula) could be found here in very low numbers. The mudflats and exposed tidal channels within the OPSP area are probably used by many of the shorebird species known to occur in the Bay Area. Mammals such as rats, striped skunks, and raccoons may forage in the salt marshes in the OPSP area, but these marshes are too limited in extent, underdeveloped in vegetation, and isolated from known populations to support salt marsh adapted mammal species such as salt marsh harvest mice (Reithrodontomys raviventris) or salt marsh wandering shrews (Sorex vagrans halicoetes). Ornamental Woodland Approximately 0.57 ac of the OPSP area is dominated by ornamental woodland. This area is located near the southwest corner of the OPSP area at the intersection of Gull Drive and Marina Boulevard. Blue gum (Eucalyptus globulus) dominates the area with a few Monterey pine (Pinus radiata) interspersed. Vegetation beneath the dense eucalyptus canopy is sparse due to canopy shading and a thick cover of leaf litter. Non-native species such as Himalayan blackberry (Rubus discolor) and French broom (Genista monspessulana) are able to survive in this environment. A few shrubs such as coyote brush, toyon, and coffeeberry (Rhamnus californica) are thriving on the sunnier edges of the woodland along with the non-native pampas grass (Cortaderia jubata). This grove of eucalyptus and Monterey pine trees is likely to host an array of common invertebrate species. The trees and shrubs provide suitable nesting habitat for common birds. The trees may also support a nest of one of the larger common raptors, such as red-shouldered hawks (Buteo lineatus), red- tailed hawks (Buteo jamaicensis), and great horned owls, all of which breed in the Project vicinity. However, due to the territorial nature of these birds, no more than one nest of one of these species would be expected to occur here. The trees could also be used as roost sites by small numbers of common roosting bats such as California myotis (Myotis californicus). Other mammals, including house mice, striped skunks, and raccoons, are also likely to forage in this area. Sandy Beach Sandy beach is present on approximately 0.38 ac within the OPSP area. This area is located at the edge of the Bay along Marina Boulevard, to the northwest of Oyster Point Marina. This area includes some habitat below the wrack indicating the high tide line as well as beach sands above the high tide line that are not typically inundated. Vegetation on the beach is sparse due to the mostly unconsolidated sand substrate, high drainage, and perpetual sand movement. Typical sandy beach species such as the native beach bur (Ambrosia chamissonis), as well as non-natives such as wild radish and sea fig are becoming established on the upper edges that do not undergo frequent disturbance. This vegetation merges with California annual grassland as the slope rises away from the water. The southern end of the beach is bordered by northern coastal salt marsh vegetation and the northern end is bordered by armored rock levee slope. Sandy beaches, relatively rare within the Bay, are home to intertidal invertebrates that serve as prey for shorebirds and seabirds. Western sandpipers and Brewer’s blackbirds (Euphagus cyanocephalus) were observed during the reconnaissance survey, foraging along the wrack line on the small sandy beach within the OPSP area. Urban-adapted mammals living in the vicinity are likely to forage opportunistically on the sandy beach; we observed two feral cats on the sandy beach during the reconnaissance survey. Due to the extremely limited extent of the sandy beach on the OPSP area, beach-nesting birds such as the western snowy plover (Charadrius alexandrinus nivosus), are not expected to occur here. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 7-8 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Open Water Open water habitat is present within approximately 0.27 ac of the OPSP area. However, extensive open water is present in the Oyster Point Marina and the Oyster Cove Marina, as well as the Bay waters surrounding the peninsula. The area is underlain with unconsolidated bay mud or gravel. The average water depth at the marina averages 5 ft; however, water depth fluctuates due to tidal fluctuation, and is typically shallower around the levees and marshes. The water temperature is cooler than what would be found in estuarine habitats and supports a diversity of algae growing on rocks and piers. Open water habitat is also present within a linear tidal canal south of Marina Boulevard. This habitat is heavily influenced by tidal fluctuations with water depth ranging from approximately 0 to 5 ft. This area has a mud substrate made up of fine silt and clay that supports little vegetation in the main canal. It is bordered on both banks by northern coastal salt marsh habitat that is thickest on the south bank. There is little evidence of significant influence from fresh water tributaries due to the lack of presence of brackish plant species. The San Francisco Bay supports a thriving community of estuarine life. Benthic invertebrates present within open water and intertidal habitats in the Project vicinity include the native Olympia oyster (Ostreola conchaphila). Native Olympia oysters were historically abundant in San Francisco Bay. Currently, populations of native oysters within the Bay are relatively low compared to historical conditions. Suitable habitat, which consists of solid surfaces to which the larvae can easily attach, is distributed throughout the shoreline of the OPSP area and on the breakwater of the Oyster Point marina, and a population has been documented in these areas. A diversity of other invertebrates provide an ample prey base for common fish, which in turn provide food sources for seabirds and marine mammals such as harbor seals (Phoca vitulina). California and western gulls, surf scoters (Melanitta perspicillata), scaup (Aythya spp.), eared grebes (Podiceps nigricollis), Clark’s grebes (Aechmophorus clarkii), western grebes (Aechmophorus occidentalis), buffleheads (Bucephala albeola), California brown pelicans (Pelecanus occidentalis), and double- crested cormorants (Phalacrocorax auritus) were observed foraging in the Bay just offshore of the OPSP area during the reconnaissance survey. During low tide, shorebirds forage on intertidal mudflats here. Fish such as starry flounder (Platichthys stellatus) that are common in estuarine waters around the San Francisco Bay could inhabit the narrow channel of estuarine water within the OPSP area. Mallards and snowy egrets were observed foraging in the channel during the reconnaissance survey, and other waterbirds are likely to forage in the channel on occasion. SPECIAL-STATUS SPECIES AND SENSITIVE HABITATS CEQA requires assessment of the effects of a project on species that are “threatened, rare, or endangered”; such species are typically described as “special-status species”. For the purpose of environmental review of the Project, special-status species have been defined as described below. Impacts to these species are regulated by some of the federal, state, and local laws and ordinances described under “Regulatory Setting” below. For purposes of this analysis, “special-status” plants are considered plant species that are: Listed under the FESA as threatened, endangered, proposed threatened, proposed endangered, or a candidate species. x Listed under the CESA as threatened, endangered, rare, or a candidate species. CHAPTER 7: BIOLOGICAL RESOURCES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 7-9 x Listed by the CNPS as rare or endangered on Lists 1A, 1B, 2, 3, or 4. For purposes of this analysis, “special-status” animals are considered animal species that are: x Listed under the FESA as threatened, endangered, proposed threatened, proposed endangered, or a candidate species. x Listed under the CESA as threatened, endangered, or a candidate threatened or endangered species. x Designated by the CDFG as a California species of special concern. x Listed in the California Fish and Game Code as a fully protected species (birds at §3511, mammals at §4700, reptiles and amphibians at §5050, and fish at §5515). Figures 3 and 4 in Appendix C depict the CNDDB-mapped records of plants and wildlife, respectively, in the vicinity of the OPSP area. These generalized maps are valuable on a historical basis, and show areas where special-status species occur or have occurred previously. Special-Status Plant Species The CNPS identifies 89 special-status plant species as potentially occurring in at least one of the seven quadrangles containing or surrounding the OPSP area or, for List 4 species, in San Mateo County. Most of these have a low likelihood of occurrence within the OPSP area due to the following reasons: lack of specific edaphic requirements on site for the species in question, the species is known to be extirpated from the area, the site is outside the highly endemic range of the species in question, the elevation range of the species is outside of the range on site, or degraded habitat conditions on site are not likely to support the species in question. Of the 89 plant species considered, only six were considered to have enough potential for occurrence in the Project vicinity, based on proximity to locally documented populations mapped by the CNDDB and similar habitat requirements to those on site, to be considered in detail. Appendix A of Appendix C lists the plants that were rejected for consideration and the reasons for rejection. The six special-status plant species considered to have some potential for occurrence on the OPSP area were reviewed in depth and are listed in Table 2 in Appendix C. Of the six species considered in this assessment, none were ultimately determined to have potential to occur on-site after careful consideration of the site’s habitats due to the site’s marginal suitability, lack of recent recorded occurrence on or in the vicinity of the site, lack of noted occurrence on site during the site visits, and the highly disturbed nature of much of the OPSP site, as discussed in detail in the full Biological Resources Report included as Appendix C. Special-status Animal Species The legal status and likelihood of occurrence of special-status wildlife species known to occur, or potentially occurring, in the general Project vicinity are presented in Table 2 in Appendix C. Figure 4 in Appendix C depicts the CNDDB-mapped locations of special-status animals in the Project vicinity. Several of the special-status species listed in Table 2 in Appendix C are not expected to occur in the OPSP area because the site lacks suitable habitat, is outside the distributions of the species, and/or is isolated from the nearest known extant populations by development or otherwise unsuitable habitat. Several other special-status species are expected to occur in the OPSP area only as uncommon to rare visitors, migrants, or transients, or may forage on the site while breeding in adjacent areas. However, these species are not expected to breed in the OPSP area in any numbers, or to be affected by Project implementation. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 7-10 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT A number of other special-status wildlife species are known or expected to occur regularly on or near the OPSP area and may breed there, or are species for which resource agencies have expressed particular concern. The species with at least some potential to occur on the OPSP site are listed below. Further information about these species as well as discussion of the special-status species determined to be absent or unlikely to occur can be found in Table 2 of Appendix C. Central California Coast steelhead (Oncorhynchus mykiss). Federally listed Threatened. Some potential to occur. Juveniles and adult steelhead could be found in the open waters adjacent to the OPSP area as they migrate to and from spawning and rearing streams in South San Francisco Bay. Populations are known from relatively nearby creeks on the peninsula (i.e., San Francisquito Creek). Southern green sturgeon (Acipenser medirostris). Federally listed Threatened. Some potential for occurrence. The species forages in the Bay, possibly including estuarine habitats near the OPSP area. The OPSP area is within designated critical habitat for this species. Longfin smelt (Spirinchus thaleichthys). State listed Threatened. Some potential for occurrence. Based on a 2009 status review, the primary distribution of larval fish is determined by outflow from the Sacramento-San Joaquin River Estuary where adults spawn. As they develop swimming ability, occasional individuals could disperse as far as the OPSP area (the species is also known to spawn in the South Bay). They are captured in the Bay as by-catch during bay shrimp (Crangon franciscorum) harvesting. California least tern (Sternula antillarum browni). Federally listed Endangered, State listed Endangered, State Protected Species. Some potential for occurrence. This species does not currently breed anywhere on the west side of South San Francisco Bay, and no suitable breeding habitat is present on the OPSP area. However, there is some potential for small numbers of individuals from East Bay or Suisun Bay breeding areas to forage in Bay waters near the OPSP area. Harlequin duck (Histrionicus histrionicus). California Species of Special Concern (breeding). Some potential for occurrence. Occasional individuals could occur in the OPSP area during the non-breeding season. However, the OPSP area is outside of the breeding range of this species and does not provide suitable breeding habitat, and this species is only a species of special concern while nesting. Black skimmer (Rynchops niger). California Species of Special Concern (breeding). Some potential for occurrence. Occasional individuals may forage in the waters immediately adjacent to the OPSP area, but there is no suitable breeding habitat on-site. This species is only a species of special concern while nesting. Northern harrier (Circus cyaneus). California Species of Special Concern (breeding). Some potential for occurrence. Breeding has been confirmed in the Project vicinity, and suitable foraging habitat exists on the OPSP area. The lack of extensive marshland or tall grasses precludes nesting on the OPSP area. This species is only a species of special concern while nesting. Vaux’s swift (Chaetura vauxi). California Species of Special Concern (breeding). Some potential for occurrence. Birds may forage in the OPSP area during the post-breeding season, but no suitable nesting habitat is available on the OPSP area. This species is only a species of special concern while nesting. Loggerhead shrike (Lanius ludovicianus). California Species of Special Concern (breeding). Some potential for occurrence. A small amount of suitable foraging habitat exists within the Phase I portion CHAPTER 7: BIOLOGICAL RESOURCES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 7-11 of the OPSP area, and up to one pair of birds could potentially breed here. Breeding shrikes have been confirmed in the Project vicinity (Sequoia Audubon Society 2001), but records in the area are few, and the OPSP area is isolated from larger patches of suitable habitat by extensive development. Most likely occurs as an occasional nonbreeding visitor, if at all. Yellow warbler (Dendroica petechia). California Species of Special Concern (breeding). Expected to occur. Expected to forage in landscaped or ornamental forest areas of the OPSP area during migration, but not expected to breed in the OPSP area, as no suitable breeding habitat is present. This species is only a species of special concern while nesting. San Francisco common yellowthroat (Geothlypis trichas sinuosa). California Species of Special Concern. May occur. Suitable emergent aquatic habitat is present in the OPSP area, and individuals have been observed on the OPSP area during the breeding season (eBird 2010). Up to a few pairs may breed in these marshes. Tricolored blackbird (Agelaius tricolor). California Species of Special Concern (breeding). Some potential for occurrence. No suitable breeding habitat is present on the OPSP area; however tricolored blackbirds may occur as occasional visitors during the non-breeding season. This species is only a species of special concern while nesting. White-tailed Kite (Elanus leucurus). State Protected Species. Some potential for occurrence. The OPSP area provides some suitable foraging habitat, and individuals have been observed in the OPSP vicinity. There are no confirmed breeding records in the OPSP area (Sequoia Audubon Society 2001). Most likely to occur as an occasional nonbreeding visitor. Sensitive and Regulated Plant Communities and Habitats The CDFG ranks certain rare or threatened plant communities, such as wetlands, meadows, and riparian forest and scrub, as ‘threatened’ or ‘very threatened’. These communities are tracked in the CNDDB. Impacts to CDFG sensitive plant communities, or any such community identified in local or regional plans, policies, and regulations, must be considered and evaluated under the California Environmental Quality Act (California Code of Regulations: Title 14, Div. 6, Chap. 3, Appendix G). Furthermore, wetland and riparian habitats are also afforded protection under applicable federal, state, or local regulations, and are generally subject to regulation, protection, or consideration by the U.S. Army Corps of Engineers (USACE), Regional Water Quality Control Board (RWQCB), CDFG, and/or the USFWS. Essential Fish Habitat is identified and regulated by the National Marine Fisheries Service (NMFS) in collaboration with regional, state and local agencies, and is defined as any habitat that is essential to the long-term survival and health of United States fisheries. Eelgrass beds are considered a sensitive resource by the USACE and CDFG because little accurate information exists about the historic distribution of eelgrass beds, and because of their current relative scarcity and importance in the overall ecology of the bay. CDFG Sensitive Habitats No sensitive habitats are mapped by the CDFG in the OPSP vicinity (Figure 3 in Appendix C). Essential Fish Habitat The tidal aquatic habitats on and adjacent to the OPSP area are considered EFH by the NMFS for a species assemblage that includes anchovies, sardines, rockfish, sharks, sole, and flounder. Areas supporting the native Olympia oyster, such as the hardened shoreline and the marina breakwater, are DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 7-12 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT also considered EFH by NMFS because oyster beds serve a number of important roles in the Bay ecosystem. Eelgrass Beds Eelgrass beds form areas of important habitat for birds, fish, and crustaceans and are one of the preferred spawning habitats of pacific herring (Wyllie-Echeverria and Fonseca 2003). These plants also support grazing crustaceans, shrimp, and amphipods. Because it requires light for photosynthesis, eelgrass is limited by water clarity to depths of about 6 feet or less. Eelgrass beds and patches occur in both subtidal and intertidal areas of the San Francisco Bay. Although no eelgrass beds or patches have been mapped closer than 3 mi from the OPSP area, the NMFS (2010) considers portions of Oyster Point to offer suitable eelgrass habitat, and there is some evidence that eelgrass populations in the Bay are expanding (Merkel & Associates 2004). Thus, we cannot rule out the possibility that eelgrass patches or beds have become established in or near the OPSP area. Waters of the U.S./State As discussed under Regulatory Setting below, open water and intertidal habitats of San Francisco Bay, the tidal canal at the southern edge of the OPSP site, and associated wetlands and shoreline areas (extending up to the high tide line or the upper limits of wetlands, whichever is higher) are considered Waters of the U.S. under the Clean Water Act and Waters of the State under the Porter-Cologne Water Quality Control Act. The approximate upslope limits of such areas are shown on Figure 7.1. These wetlands and aquatic habitats are also important habitats for a variety of animal species. REGULATORY SETTING This section describes the local, state, and federal plans, policies, and laws that are relevant to biological, resources and that are applicable to the OPSP. FEDERAL Clean Water Act Areas meeting the regulatory definition of “Waters of the U.S.” (jurisdictional waters) are subject to the jurisdiction of the United States Army Corps of Engineers (USACE) under provisions of Section 404 of the 1972 Clean Water Act (Federal Water Pollution Control Act) and Section 10 of the 1899 Rivers and Harbors Act (described below). These waters may include all waters used, or potentially used, for interstate commerce, including all waters subject to the ebb and flow of the tide, all interstate waters, all other waters (intrastate lakes, rivers, streams, mudflats, sandflats, playa lakes, natural ponds, etc.), all impoundments of waters otherwise defined as “Waters of the U.S.,” tributaries of waters otherwise defined as “Waters of the U. S.,” the territorial seas, and wetlands (termed Special Aquatic Sites) adjacent to “Waters of the U.S.” (33 CFR, Part 328, Section 328.3). Wetlands on non-agricultural lands are identified using the Corps of Engineers Wetlands Delineation Manual (Environmental Laboratory 1987). Areas typically not considered to be jurisdictional waters include non-tidal drainage and irrigation ditches excavated on dry land, artificially-irrigated areas, artificial lakes or ponds used for irrigation or stock watering, small artificial water bodies such as swimming pools, and water-filled depressions (33 CFR, Part 328). CHAPTER 7: BIOLOGICAL RESOURCES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 7-13 Construction activities within jurisdictional waters are regulated by the USACE. The placement of fill into such waters must comply with permit requirements of the USACE. No USACE permit will be effective in the absence of state water quality certification pursuant to Section 401 of the Clean Water Act. The State Water Resources Control Board (SWRCB) is the state agency (together with the Regional Water Quality Control Boards [RWQCBs]) charged with implementing water quality certification in California. OPSP Applicability: Any work within areas defined as Waters of the U.S. (i.e., wetlands and other waters), including open water and intertidal habitats of San Francisco Bay, the tidal canal at the southern edge of the OPSP site, and associated wetlands and shoreline areas (extending up to the high tide line or the upper limits of wetlands, whichever is higher) may require a Section 404 fill discharge permit from the USACE and Section 401 Water Quality Certification from the RWQCB. The approximate upslope limits of USACE jurisdiction under the Clean Water Act are shown on Figure 7.1. A jurisdictional wetland delineation to determine the precise boundaries of USACE jurisdiction has not been performed for the OPSP. Porter-Cologne Water Quality Control Act The RWQCB is responsible for protecting surface, ground, and coastal waters within its boundaries, pursuant to the Porter-Cologne Water Quality Control Act of the California Water Code. The RWQCB has jurisdiction under Section 401 of the Clean Water Act for activities that could result in a discharge of dredged or fill material to a water body. Federal authority is exercised whenever a proposed project requires a Clean Water Act Section 404 permit from the USACE in the form of a Section 401 Water Quality Certification. State authority is exercised when a proposed project is not subject to federal authority, in the form of a Notice of Coverage, Waiver of Waste Discharge Requirements. Many wetlands fall into RWQCB jurisdiction, including some wetlands and waters that are not subject to USACE jurisdiction. RWQCB jurisdiction of other waters, such as streams and lakes, extends to all areas below the ordinary high water mark. The RWQCB has no formal technical manual or expanded regulations to help in identifying their jurisdiction. The only guidance can be found in Porter-Cologne Water Quality Control Act, Chapter 2 (Definitions), which states, “‘waters of the State’ means any surface water or ground water, including saline waters, within the boundaries of the state.” Under the Porter-Cologne Water Quality Control Act, the SWRCB and the nine regional boards also have the responsibility of granting Clean Water Act National Pollutant Discharge Elimination System (NPDES) permits and waste discharge requirements for certain point-source and non-point discharges to waters. These regulations limit impacts to aquatic and riparian habitats from a variety of urban sources. OPSP Applicability: As stated above, any OPSP activities that impact waters of the U.S./State will require 401 Certification and/or a Waste Discharge Requirement from the RWQCB. In the Study Area, these include the same boundaries of aquatic, intertidal, and wetlands/shoreline habitats as described above for areas subject to jurisdiction under the Clean Water Act. Rivers and Harbors Act Section 10 of the Rivers and Harbors Act (1899) 33 U.S.C. 403 regulates the construction of structures, placement of fill, and introduction of other potential obstructions to navigation in navigable waters. Under Section 10 of the Act, the building of any wharfs, piers, jetties, and other structures is prohibited DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 7-14 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT without Congressional approval, and excavation or fill within navigable or tidal waters requires the approval of the Chief of Engineers. The USACE has the authority to issue permits for the discharge of refuse into, or affecting, navigable waters under section 13 of the 1899 Act (33 U.S.C. 407; 30 Stat. 1152). The Act was modified by title IV of P.L. 92-500, October 18, 1972; the Federal Water Pollution Control Act Amendments of 1972 (33 U.S.C. 1341-1345; 86 Stat. 877), as amended, established the NPDES permits. OPSP Applicability: Within the OPSP area, all tidally influenced open water and intertidal habitats of San Francisco Bay, the tidal canal at the southern edge of the OPSP site, and associated wetlands and shoreline areas (extending up to the mean high water line) are subject to USACE jurisdiction under the Rivers and Harbors Act, and any activities affecting these areas would potentially require a Section 10 Letter of Permission. Federal Endangered Species Act The federal Endangered Species Act (FESA) protects listed wildlife species from harm or “take” which is broadly defined as to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, collect, or attempt to engage in any such conduct. Take can also include habitat modification or degradation that directly results in death or injury of a listed wildlife species. An activity can be defined as “take” even if it is unintentional or accidental. Listed plant species are provided less protection than listed wildlife species. Listed plant species are legally protected from take under the FESA only if they occur on federal lands or if the project requires a federal action, such as a Clean Water Act Section 404 fill permit from the USACE. The U. S. Fish and Wildlife Service (USFWS) has jurisdiction over federally listed threatened and endangered wildlife species under the FESA, while the National Marine Fisheries Service (NMFS) has jurisdiction over federally listed, threatened and endangered, marine and anadromous fish. OPSP Applicability: Several federally listed species occur in the general vicinity of the OPSP area. Although only limited habitat for such species occurs in the OPSP area, federally listed animal species that occur, or could potentially occur, in the OPSP area include the green sturgeon (Acipenser medirostris), Central California Coast steelhead (Oncorhynchus mykiss), and California least tern (Sterna antillarum browni), and possibly several Central Valley-breeding salmonids. Magnuson-Stevens Fishery Conservation and Management Act The Magnuson-Stevens Fishery Conservation and Management Act governs all fishery management activities that occur in federal waters within the United States’ 200-nautical-mile limit. The Act establishes eight Regional Fishery Management Councils responsible for the preparation of fishery management plans to achieve the optimum yield from U.S. fisheries in their regions. These councils, with assistance from the NMFS, establish Essential Fish Habitat (EFH) in fishery management plans for all managed species. Federal agencies that fund, permit, or implement activities that may adversely affect EFH are required to consult with the NMFS regarding potential adverse effects of their actions on EFH, and respond in writing to recommendations by the NMFS. OPSP Applicability: A number of fish species regulated by the Coastal Pelagics and Pacific Groundfish Fisheries Management Plans occur in tidal habitats of San Francisco Bay, including the open water habitats on and adjacent to the OPSP area. Thus, these tidal waters are considered EFH. CHAPTER 7: BIOLOGICAL RESOURCES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 7-15 Marine Mammal Protection Act The Marine Mammal Protection Act (MMPA) was enacted in 1972 and amended through 2007 (16 USC 1631). All marine mammals are protected by the MMPA, which prohibits their take in U.S. Waters. Take is defined in the MMPA as “harass, hunt, capture, kill or collect, or attempt to harass, hunt, capture, kill or collect” [16 USC 1631 Section 3(13)]. OPSP Applicability: The only two marine mammal species that have potential to occur in the OPSP vicinity at all regularly are the harbor seal and the California sea lion (Zalophus californianus), both of which may occasionally forage in Bay waters near the OPSP site. The MMPA would apply to the OPSP, because in-water construction activities such as pile driving could potentially harass these animals. Federal Migratory Bird Treaty Act The federal Migratory Bird Treaty Act (MBTA; 16 U.S.C., §703, Supp. I, 1989) prohibits killing, possessing, or trading of migratory birds except in accordance with regulations prescribed by the Secretary of the Interior. The trustee agency that addresses issues related to the MBTA is the USFWS. Migratory birds protected under this law include all native birds and certain game birds (e.g., turkeys and pheasants; Federal Register 70(2):372-377). This act encompasses whole birds, parts of birds, and bird nests and eggs. The MBTA protects active nests from destruction and all nests of species protected by the MBTA, whether active or not, cannot be possessed. An active nest under the MBTA, as described by the Department of the Interior in its 16 April 2003 Migratory Bird Permit Memorandum, is one having eggs or young. Nest starts, prior to egg laying, are not protected from destruction. OPSP Applicability: All native bird species occurring in the Study Area are protected by the MBTA. STATE California Endangered Species Act The California Endangered Species Act (CESA, Fish and Game Code of California, Chapter 1.5, Sections 2050-2116) prohibits the take of any plant or animal listed or proposed for listing as rare (plants only), threatened, or endangered. In accordance with the CESA, the CDFG has jurisdiction over state-listed species. The CDFG regulates activities that may result in “take” of individuals listed under the Act (i.e., “hunt, pursue, catch, capture, or kill, or attempt to hunt, pursue, catch, capture, or kill”). Habitat degradation or modification is not expressly included in the definition of “take” under the Fish and Game Code. The CDFG, however, has interpreted “take” to include the “killing of a member of a species which is the proximate result of habitat modification.” OPSP Applicability: Although habitat suitability in the OPSP area for these species is marginal, State- listed animal species that occur, or could potentially occur, in the OPSP area include the longfin smelt (Spirinchus thaleichthys) and California least tern. California Environmental Quality Act The California Environmental Quality Act (CEQA) is a state law that requires state and local agencies, such as the City of South San Francisco, to document and consider the environmental implications of their actions and to refrain from approving projects with significant environmental effects if there are feasible alternatives or mitigation measures that can substantially lessen or avoid those effects. CEQA requires the full disclosure of the environmental effects of agency actions, such as approval of a general plan update or the projects covered by that plan, on resources such as air quality, water quality, cultural DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 7-16 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT resources, and biological resources. The State Resources Agency promulgated guidelines for implementing CEQA known as the State CEQA Guidelines. CEQA and the CEQA Guidelines provide guidance in evaluating impacts of projects to biological resources and determining which impacts will be significant. CEQA defines “significant effect on the environment” as “a substantial adverse change in the physical conditions which exist in the area affected by the proposed project.” Under CEQA Guidelines section 15065, a project's effects on biotic resources are deemed significant where the project would: “substantially reduce the habitat of a fish or wildlife species” “cause a fish or wildlife population to drop below self-sustaining levels” “threaten to eliminate a plant or animal community” “reduce the number or restrict the range of a rare or endangered plant or animal” In addition to the section 15065 criteria that trigger mandatory findings of significance, Appendix G of the CEQA Guidelines provides a checklist of other potential impacts to consider when analyzing the significance of project effects. The impacts listed in Appendix G may or may not be significant, depending on the level of the impact. For biological resources, these impacts include whether the project would: “have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Service” “have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, regulations or by the California Department of Fish and Game or U.S. Fish and Wildlife Service” “have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act” “interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites” “conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance” “conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan” Section 15380(b) of the CEQA Guidelines provides that a species not listed on the federal or state lists of protected species may be considered rare if the species can be shown to meet certain specified criteria. These criteria have been modeled after the definitions in the FESA and the CESA and the section of the California Fish and Game Code dealing with rare or endangered plants or animals. This section was included in the guidelines primarily to deal with situations in which a public agency is CHAPTER 7: BIOLOGICAL RESOURCES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 7-17 reviewing a project that may have a significant effect on a species that has not yet been listed by either the USFWS or CDFG or species that are locally or regionally rare. The CDFG has produced three lists (amphibians and reptiles, birds, and mammals) of “species of special concern” that serve as “watch lists”. Species on these lists are of limited distribution or the extent of their habitats has been reduced substantially, such that threat to their populations may be imminent. Thus, their populations should be monitored. They may receive special attention during environmental review as potential rare species, but do not have specific statutory protection. All potentially rare or sensitive species, or habitats capable of supporting rare species, are considered for environmental review per the CEQA § 15380(b). The CNPS, a non-governmental conservation organization, has developed lists of plant species of concern in California. Vascular plants included on these lists are defined as follows: List 1A Plants considered extinct. List 1B Plants rare, threatened, or endangered in California and elsewhere. List 2 Plants rare, threatened, or endangered in California but more common elsewhere. List 3 Plants about which more information is needed - review list. List 4 Plants of limited distribution-watch list. These CNPS listings are further described by the following threat code extensions: .1—seriously endangered in California; .2—fairly endangered in California; .3—not very endangered in California. Although the CNPS is not a regulatory agency and plants on these lists have no formal regulatory protection, plants appearing on List 1B or List 2 are, in general, considered to meet the CEQA’s Section 15380 criteria, and adverse effects to these species may be considered significant. Impacts to plants that are listed by the CNPS on List 3 or 4 are also considered during CEQA review, although because these species are typically not as rare as those on List 1B or List, impacts to them are less frequently considered significant. OPSP Applicability: All impacts to biological resources will be considered during CEQA review of the OPSP in the context of this EIR. California Fish and Game Code The California Fish and Game Code includes regulations governing the use of, or impacts to, many of the state’s fish, wildlife, and sensitive habitats. The CDFG exerts jurisdiction over the bed and banks of rivers, lakes, and streams according to provisions of §§1601–1603 of the Fish and Game Code. The Fish and Game Code requires a Streambed Alteration Agreement for the fill or removal of material within the bed and banks of a watercourse or waterbody and for the removal of riparian vegetation. Certain sections of the Fish and Game Code describe regulations pertaining to certain wildlife species. For example, Fish and Game Code §§3503, 2513, and 3800 (and other sections and subsections) DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 7-18 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT protect native birds, including their nests and eggs, from all forms of take. Disturbance that causes nest abandonment and/or loss of reproductive effort is considered “take” by the CDFG. Raptors (i.e., eagles, falcons, hawks, and owls) and their nests are specifically protected in California under Fish and Game Code §3503.5. Section 3503.5 states that it is “unlawful to take, possess, or destroy any birds in the order Falconiformes or Strigiformes (birds of prey) or to take, possess, or destroy the nest or eggs of any such bird except as otherwise provided by this code or any regulation adopted pursuant thereto.” Non-game mammals are protected by Fish and Game Code §4150, and other sections of the Code protect other taxa. OPSP Applicability: All native bird and mammal species that occur in the OPSP area are protected by the state Fish and Game Code. Because no non-tidal creeks are present in the OPSP area, it is unlikely that a Streambed Alteration Agreement would be required for OPSP activities. REGIONAL McAteer-Petris Act The McAteer-Petris Act created the San Francisco Bay Conservation and Development Commission (BCDC) in 1965. BCDC’s mission is to preserve the San Francisco Bay from unregulated filling. BCDC has prepared a comprehensive study of the Bay and determined how future development of the Bay should occur, resulting in the production of the San Francisco Bay Plan in 1968. BCDC’s jurisdiction includes all areas below the mean high tide line and an area within a shoreline band that extends landward for 100 feet from the mean high tide line. The McAteer-Petris Act includes a permitting process for projects that would place fill in, on, or over any part of BCDC’s jurisdiction. OPSP Applicability: Portions of the OPSP in, on, or over the Bay, including areas within 100 feet of the mean high tide elevation (or, in areas supporting coastal wetlands, within 100 feet of the mean high tide elevation plus 5 feet), are within BCDC’s jurisdiction, and BCDC approval of any activities within these areas would be required. City of South San Francisco Tree Preservation Ordinance Under Chapter 13.30 of the South San Francisco Municipal Code, the City of South San Francisco maintains a tree preservation ordinance designed to: (a) Provide standards and requirements for the protection of certain large trees (trees with a circumference of 48 inches or greater at 54 inches above the natural grade) and trees and stands with unique characteristics (having been so designated by the Parks and Recreation director); (b) Provide standards and requirements for planting and maintenance of trees for new development; and (c) Establish recommended standards for planting and maintaining trees on property that is already developed. This chapter achieves these objectives in ways that support and encourage the reasonable economic enjoyment of private property, not in ways that prevent it. (Ord. 1271 § 1 (part), 2000: Ord. 1060 § 1 (part), 1989). Protected trees are not to be removed or pruned without a permit from the City, and must be protected from development-related impacts such as soil compaction and underground trenching for utilities. Additionally, new developments must conform to a series of tree planting requirements. CHAPTER 7: BIOLOGICAL RESOURCES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 7-19 OPSP Applicability: No trees of protected size or that were known to be protected by special designation from the Parks and Recreation director (as demarcated by a fence) were found to occur on- site. As the Oyster Point Business Park will be located in an areas designated as community commercial, business commercial, coastal commercial, office or business and technology park, one landscape tree must be planted for every 2000 square feet of new floor area. IMPACTS AND MITIGATION MEASURES CRITERIA OF IMPACT SIGNIFICANCE The proposed OPSP may have effects on the biological resources of the OPSP area. The California Environmental Quality Act (CEQA) and the CEQA Guidelines provide guidance in evaluating project impacts and determining which impacts will be significant. CEQA defines “significant effect on the environment” as “a substantial adverse change in the physical conditions which exist in the area affected by the proposed project.” Under CEQA Guidelines section 15065(a)(1) and Appendix G, a project’s effects on biotic resources may be significant when the project would: 1. have the potential to degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory 2.have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Service 3.have a substantial adverse effect on any riparian habitat or other sensitive natural community (e.g., oak woodland) identified in local or regional plans, policies, regulations or by the California Department of Fish and Game or U.S. Fish and Wildlife Service 4.have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act 5.interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites 6.conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance 7.conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan The following impact analyses consider the project-specific impacts of proposed Phase I activities and the programmatic impacts of other activities that could be performed as part of the OPSP. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 7-20 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Key Assumptions for the Phase I Project x No grading or placement of fill, either temporary or permanent, will occur in any aquatic or wetland habitat (i.e., within the “Approximate Limit of USACE Jurisdiction” indicated on Figure 7.1) during Phase I Project activities. x The tallest building to be constructed in Phase I is 10 stories high. x Lighting will be in conformance with the OPSP’s lighting guidelines. Key Assumptions for the Remainder of the OPSP x The tallest of the new office/R&D buildings to be constructed outside the Phase I area will be no more than 10 stories high. x Lighting will be in conformance with the OPSP’s lighting guidelines. HABITAT MODIFICATION Terrestrial Habitats Impact Bio-1: Loss of Common Terrestrial Habitats. Development of the OPSP would result in the modification or loss of Developed and Landscaped areas, California Annual Grassland/Coyote Brush Scrub, Ornamental Woodland Habitats and Non- Jurisdictional Armored Rock Levee Slope Habitats. However, none of these habitats represent particularly sensitive, valuable (from the perspective of providing important wildlife habitat), or exemplary occurrences of these habitat types. Therefore, impacts to these habitats, and the loss of potential nesting, roosting, and foraging opportunities associated with such habitats, are considered a less-than-significant impact. Phase I construction may result in the loss or conversion of up to 20.05 ac of developed and landscaped areas, 14.20 ac of California annual grassland/coyote brush scrub, and 0.57 ac of ornamental woodland habitat due to the construction of buildings, landscaping, and other activities. These habitats are located within the boundary of Phase I of the OPSP, and above USACE jurisdiction. An additional 0.72 acres of northern coastal salt marsh, 0.01 acres of armored rock levee slope, and 0.11 acres of sandy beach habitat are located within the boundary of Phase I of the OPSP and within USACE jurisdiction; however, these areas will be avoided during construction. Portions of the OPSP area outside of the Phase I boundary contain 37.11 ac of developed and landscaped areas, 4.54 ac of California annual grassland/coyote brush scrub, and 1.04 ac of armored rock levee slope habitats. As a result, there is some potential for some or all of these habitats to be lost or modified due to the construction of buildings, installation of landscaping, and other activities. These habitats are located above the approximate limits of USACE jurisdiction. Impacts to these habitats during construction activities will reduce the extent of these habitat types on the OPSP area, and will result in a reduction in abundance of some of the common wildlife species that use the site. However, these habitat types are relatively abundant and widespread regionally, and none of the habitats to be impacted by the OPSP represent sensitive, valuable (from the perspective of providing important wildlife habitat), or exemplary occurrences of these habitat types. Therefore, impacts to these habitats, and the loss of potential nesting, roosting, and foraging opportunities associated with such habitats, are considered a less-than-significant impact. CHAPTER 7: BIOLOGICAL RESOURCES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 7-21 Wetland or Aquatic Habitats Impact Bio-2: Disturbance or Loss of Wetland or Aquatic Habitats. Development of the OPSP would result in the disturbance or loss of Northern Coastal Salt Marsh, Open Water and Jurisdictional Armored Rock Levee Slope Habitats. Due to the ecological importance of wetland and aquatic habitats, such impacts would be potentially significant. A total of 1.74 acres of northern coastal salt marsh, 0.27 acres of open water (including intertidal habitats), and 0.76 acres of armored rock levee slope below the approximate limits of USACE jurisdiction are present within the OPSP area outside of the boundaries of Phase I activities. While the actual acreage of impacts to these sensitive/jurisdictional habitats is unknown, it is possible that these habitats could be impacted due to the construction of buildings, marina improvements, Bay Trail improvements, landscaping, and other activities. Additional wetland and open water habitat, within the “Additional Study Area” but outside the OPSP boundaries (see Figure 2 in Appendix C), could potentially be impacted by marina improvements, such as addition or replacement of piers and reconstruction of docks, and by shading from such structures. Mitigation Measures Bio-2a: Delineate Jurisdictional Boundaries. Prior to construction of any programmatic OPSP elements that are expected to potentially have direct impacts on USACE jurisdictional habitats, a focused delineation shall be performed to determine the precise limits of USACE jurisdiction at the site, and USACE approval of the jurisdictional boundaries will be obtained. Bio- 2b: Impact Avoidance/Minimization. Future OPSP elements near the Bay shoreline shall be designed with consideration of the boundaries of sensitive wetland and aquatic habitats in order to avoid and minimize impacts to these sensitive habitats to the extent practicable while still accomplishing OPSP objectives. For example, building and trail construction, landscaping activities, and other terrestrial activities shall be planned and designed to avoid impacting the sensitive habitats near the Bay shoreline to the extent feasible. For activities that cannot avoid impacting sensitive habitats due to their water-related purpose or location, such as construction or replacement of piers or docks in the marina, the amount of new fill or the footprint of new structures placed in or on the water shall be limited to the minimum necessary to achieve the objectives of that component. The City shall review plans for any proposed activities that will result in impacts to sensitive wetland and aquatic habitats to ensure that impacts have been avoided and minimized to the extent feasible. Bio-2c: Restoration of Temporarily Impacted Wetland/Aquatic Habitats. USACE- jurisdictional areas that are temporarily impacted during construction of programmatic elements shall be restored to preexisting contours and levels of soils compaction following build-out. The means by which such temporarily impacted areas will be restored shall be described in the mitigation plan described in Measure 2d below. Bio-2d: Compensation for Permanently Impacted Wetland/Aquatic Habitats. Unavoidable permanent fill of all habitats within USACE jurisdiction shall be replaced at a minimum 1:1 (mitigation area: impact area) ratio by creation or restoration of similar habitat around San Francisco Bay. Any aquatic, marsh, or DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 7-22 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT mudflat habitat areas experiencing a net increase in shading as a result of docks or other structures constructed over or on the water shall require compensatory mitigation at a 0.5:1 (mitigation area: impact area) ratio; this ratio is less than the 1:1 required for permanent filling of such habitats because shaded areas are expected to retain some ecological habitat value. Mitigation could be achieved through a combination of on-site restoration or creation of wetlands or aquatic habitats (including removal of on-site fill or structures, resulting in a gain of wetland or aquatic habitats); off-site restoration/creation; funding of off-site restoration/creation projects implemented by others; and/or mitigation credits purchased at mitigation banks within the San Francisco Bay Region. Because impacts to aquatic habitats on-site could also potentially impact special-status fish and EFH (see Impacts to Essential Fish Habitat and Special-Status Fish below), all compensatory mitigation for impacts to aquatic habitat must also provide habitat for green sturgeon, Central California Coast steelhead, and longfin smelt that is of a quality at least as high as that impacted. For funding of off-site improvements or purchase of mitigation bank credits, the OPSP Applicant shall provide written evidence to the City that either (a) compensation has been established through the purchase of a sufficient number of mitigation credits in a mitigation bank to satisfy the mitigation acreage requirements of the OPSP activity, or (b) funds sufficient for the restoration of the mitigation acreage requirements of the OPSP activity have been paid to an entity implementing a project that would create or restore habitats of the type being impacted by the OPSP. For areas to be restored to mitigate for temporary or permanent impacts, the OPSP Applicant shall prepare and implement a mitigation plan. The OPSP Applicant shall retain a restoration ecologist or wetland biologist to develop the mitigation plan, and it shall contain the following components (or as otherwise modified by regulatory agency permitting conditions): 1. Summary of habitat impacts and proposed mitigation ratios, along with a description of any other mitigation strategies used to achieve the overall mitigation ratios, such as funding of off-site improvements and/or purchase of mitigation bank credits 2.

Mitigation design: x Existing and proposed site hydrology x Grading plan if appropriate, including bank stabilization or other site stabilization features x Soil amendments and other site preparation elements as appropriate x Planting plan x Irrigation and maintenance plan x Remedial measures/adaptive management, etc. 5. Monitoring plan (including final and performance criteria, monitoring methods, data analysis, reporting requirements, monitoring schedule, etc.) CHAPTER 7: BIOLOGICAL RESOURCES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 7-23 6. Contingency plan for mitigation elements that do not meet performance or final success criteria. Implementation of mitigation measures Bio-2a through Bio-2d would reduce impacts related to disturbance or loss of wetland and aquatic habitats to a less-than-significant level through delineations of jurisdictional areas, avoidance or minimization of impacts through specifics of design as possible, restoration of temporarily impacted areas where feasible, and compensation for/replacement of impacted habitat when loss cannot be avoided. Indirect Impacts to Water Quality and Sensitive Habitats Impact Bio-3: Construction-Period Increases in Turbidity. Sediment may wash from construction areas into adjacent aquatic habitats, or soil loosened by grading could slide downslope into such areas. Increases in turbidity resulting from construction constitutes a potentially significant impact to aquatic wildlife species, including special-status fish species such as steelhead and sensitive native species such as the Olympia oyster. Water quality degradation could also negatively impact eelgrass beds if they occur in the OPSP area. Due to the ecological importance of these aquatic habitats and sensitive resources, such impacts would be potentially significant. Construction in and near drainage channels, storm drains, or the Bay could have a significant adverse effect on water quality in the Bay within and adjacent to the OPSP area due to increased turbidity, if ground-disturbing activities occur during the wet season, if soil is allowed to enter channels or storm drains, or if dredging or other substrate-disturbing activities take place within the Bay. Some grading, construction, and landscaping will occur in close proximity to, and upslope from, sensitive aquatic habitats. There is thus some potential for construction activities to result in indirect effects on these habitats and on water quality in adjacent aquatic habitats. For example, in the absence of measures to prevent erosion and sedimentation, sediment may wash from construction areas into adjacent aquatic habitats, or soil loosened by grading could slide downslope into such areas. Such impacts could result in the loss or degradation of wetland or aquatic habitats, and degradation of water quality in adjacent waters. Mitigation Measures Bio-3a: Incorporate Best Management Practices for Water Quality During Construction. The Plan shall incorporate Best Management Practices (BMPs) for water quality to minimize impacts in the surrounding wetland environment, sloughs and channels, and the San Francisco Bay during construction. These BMPs shall include numerous practices that will be outlined within the Stormwater Pollution Prevention Plan (SWPPP), including, but not limited to, the following mitigation measures: 1.No equipment will be operated in live flow in any of the sloughs or channels or ditches on or adjacent to the site. 2.No debris, soil, silt, sand, bark, slash, sawdust, cement, concrete, washings, petroleum products or other organic or earthen material shall be allowed to enter into or be placed where it may be washed by rainfall or runoff into aquatic or wetland habitat. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 7-24 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT 3.Standard erosion control and slope stabilization measures will be required for work performed in any area where erosion could lead to sedimentation of a waterbody. For example, silt fencing will be installed just outside the limits of grading and construction in any areas where such activities will occur upslope from, and within 50 ft of, any wetland, aquatic, or marsh habitat. This silt fencing will be inspected and maintained regularly throughout the duration of construction. 4.Machinery will be refueled at least 50 ft from any aquatic habitat, and a spill prevention and response plan will be developed. All workers will be informed of the importance of preventing spills and of the appropriate measures to take should a spill occur. Bio-3b: Minimize Soil Disturbance Adjacent to Wetland and Marsh Habitat. To the extent feasible, soil stockpiling, equipment staging, construction access roads, and other intensively soil-disturbing activities shall not occur immediately adjacent to any wetlands that are to be avoided by the OPSP. The limits of the construction area shall be clearly demarcated with Environmentally Sensitive Area fencing to avoid inadvertent disturbance outside the fence during construction activities. Implementation of mitigation measures Bio-3a and Bio-3b would reduce indirect impacts to water quality and sensitive habitats from construction-period increases in turbidity to a less-than-significant level through minimization of soil disturbance adjacent to these habitats and implementation of best management practices for water quality during construction. Impact Bio-4: Operational Stormwater Impacts on Wetlands and a Tidal Channel. Installation of stormwater outfalls from the buildings to be constructed in the southwestern part of the site shall outfall into vegetated swales that are to be constructed just upslope from the wetlands and tidal channel that form the southwestern boundary of the site. If these swales are not adequately constructed, there is some potential for excessive erosion or the release of untreated runoff into these wetlands and tidal waters. Due to the value of wetland habitats to the ecology of the Bay’s aquatic habitats and the value of these aquatic habitats to a variety of fish, benthic organisms, and other species, degradation of water quality or wetlands would be a potentially significant impact. Mitigation Measure Bio-4: Ensure Adequate Stormwater Run-off Capacity. Increases in stormwater run- off due to increased hardscape shall be mitigated through the construction and maintenance of features designed to handle the expected increases in flows and provide adequate energy dissipation. All such features, including outfalls, shall be regularly maintained to ensure continued function and prevent failure following construction. Implementation of mitigation measure Bio-4 would reduce indirect impacts to wetland and aquatic habitats related to stormwater outfalls to a less-than-significant level through assuring adequate capacity and maintenance of the stormwater system. Habitat for and Individuals of Non-Breeding Special-Status Wildlife Species Impact Bio-5: Loss of Habitat for Non-breeding Special-Status Wildlife Species. Several terrestrial special-status species may use the OPSP area as transients or migrants, CHAPTER 7: BIOLOGICAL RESOURCES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 7-25 or may occur in very low numbers, but are not expected to breed at the site or to be present in any numbers. These species include the American peregrine falcon, black skimmer, harlequin duck, northern harrier, Vaux’s swift, yellow warbler, tricolored blackbird, white-tailed kite and loggerhead shrike. There would be no substantial loss of foraging or non-breeding habitat for any of these species, as the OPSP footprint primarily includes already developed and/or heavily impacted areas. Therefore, the impact on non-Breeding Special-Status Wildlife Species would be less-than-significant. American peregrine falcons have been observed occasionally on the OPSP area and throughout the OPSP vicinity; the nearest confirmed breeding location is on Bair Island near Redwood City (Sequoia Audubon Society 2001). This species is uncommon throughout the Bay Area, and does not occur frequently or in large numbers in the OPSP area. Black skimmers and California least terns are known to occur in the Bay in low numbers throughout the year, and a small breeding population of each species has become established in the South Bay. However there is no suitable nesting habitat for these species on the OPSP area and individuals are expected to forage in the small amount of marine aquatic habitat within the OPSP area rarely if at all. Harlequin ducks occur regularly in low numbers in the OPSP vicinity during the non-breeding season only. The OPSP area is outside of the known breeding range of the species (Robertson and Goudie 1999), and individuals are expected to occur in the OPSP area rarely if at all. Northern harriers breed in San Mateo County (Sequoia Audubon Society 2001) and are regularly observed in grassy and marshy habitats throughout the year. Occasional individuals may forage in the grassy habitats on the OPSP area, but harriers are not expected to occur there in any numbers, or to nest on the site. Vaux’s swifts may occasionally forage for insects over the OPSP area, but would not roost there, nor would they occur frequently or in large numbers. Yellow warblers have been observed in the OPSP vicinity during migration, and the species forages in the OPSP area during migratory periods. However, the species is not expected to nest on the OPSP area. Tricolored blackbirds may occasionally forage in open grassy or ruderal portions of OPSP area, but records of birds in the vicinity are few, and they are not expected to occur there in any numbers or to nest on the site. The white-tailed kite and loggerhead shrike could possibly also forage in the portion of the OPSP area outside the Phase I area, but they are not expected to nest here. OPSP construction would not result in injury or mortality of any individuals of these species, which are mobile enough to avoid construction equipment. There would be no substantial loss of foraging or non- breeding habitat for any of these species, as the OPSP footprint primarily includes already developed and/or heavily impacted areas. As a result, the OPSP’s impacts do not meet the CEQA standard of having a substantial adverse effect on these species’ populations, and the OPSP will have a less than significant impact on these species. Habitat for and Individuals of Certain Potentially Nesting Special-Status Birds Impact Bio-6: Disturbance of Special-Status Nesting Birds. Construction-related noise and activity could disturb or displace special-status breeding birds. The number of nesting individuals that could be disturbed is very small, and the OPSP’s impacts would not substantially reduce regional populations of special-status bird species, and thus these impacts do not meet the CEQA standard of having a substantial adverse effect on these species. However, the loss of any active nests of protected birds would be in violation of federal and state laws, thus this impact would be considered potentially significant. Some special-status bird species could potentially nest in or adjacent to the OPSP area but are not expected to be significantly impacted by the OPSP. These species include the white-tailed kite and DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 7-26 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT loggerhead shrike, for which there is a very low probability of nesting, as well as the San Francisco common yellowthroat, Alameda song sparrow, and Bryant’s savannah sparrow, which have a somewhat higher probability of nesting in wetland vegetation at the periphery of the site. White-tailed kites and loggerhead shrikes are uncommon to rare on the Peninsula due to the scarcity of suitable grassland habitat, and due to the limited extent of foraging habitat and disturbance, there is a low probability that either species nests on the site. Nevertheless, there is some potential for up to one pair of each species to nest in the southwestern portion of Phase I of the OPSP area. Any such nesting pairs would be displaced by OPSP activities. Therefore, a small amount of marginal nesting and foraging habitat will be removed as a result of OPSP activities. San Francisco common yellowthroats occur throughout the Bay Area in tidal marshes and nearby freshwater riparian areas. Common yellowthroats have been observed in the OPSP area, and enough suitable nesting habitat exists on the OPSP area that up to two pairs of common yellowthroats could establish nesting territories in wetland vegetation along the tidal channel south of the OPSP area or just outside the northwestern part of the OPSP area. OPSP activities will not result in the loss of any nesting or foraging habitat, but breeding individuals could be disturbed or displaced by construction-related noise and activity. Alameda song sparrows are restricted to salt marsh habitat, which will not be impacted by Phase I of the proposed OPSP. Bryant’s savannah sparrows utilize salt marsh habitat as well, but can also be found in adjacent ruderal or grassland habitats, which will be lost as a result of OPSP activities. Pairs of song sparrows or savannah sparrows nesting in the salt marsh habitat within the OPSP area could be disturbed by noise, movement, and other construction activities. Any pairs of savannah sparrows nesting in the ruderal or grassland areas within the Phase I footprint would be displaced by OPSP activities. However, the amount of salt marsh habitat in the OPSP area is small and the quality is low, and thus the number of pairs of these species that could potentially be disturbed due to OPSP activities represents a very small fraction of the regional population. Likewise, the number of savannah sparrows that could potentially nest in the small patch of ruderal grassland habitat within the Phase I footprint is low. Because the amount and quality of habitat for white-tailed kites, loggerhead shrikes, San Francisco common yellowthroats, Alameda song sparrows, and Bryant’s savannah sparrows being impacted is low, and the number of nesting individuals that could be disturbed is very small, the OPSP’s impacts would not substantially reduce regional populations of these species, and thus these impacts do not meet the CEQA standard of having a substantial adverse effect on these species. However, the loss of any active nests of protected birds would be in violation of federal and state laws (see Regulatory Setting above). Mitigation Measure Bio-6: Pre-Construction Nesting Bird Survey. Pre-construction surveys for nesting birds protected by the Migratory Bird Treaty Act of 1918 and/or Fish and Game Code of California within 100 feet of a development site in the OPSP area shall be conducted if construction commences during the avian nesting season, between February 1 and August 31. The survey should be undertaken no more than 15 days prior to any site-disturbing activities, including vegetation removal or grading. If active nests are found, a qualified biologist shall determine an appropriate buffer in consideration of species, stage of nesting, location of the nest, and type of construction activity. The buffers should be maintained until after the nestlings have fledged and left the nest. CHAPTER 7: BIOLOGICAL RESOURCES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 7-27 Implementation of pre-construction nesting bird surveys as called for in Mitigation Measure Bio-6 would reduce the impacts related to disturbance of nesting special-status birds to a less-than- significant level. DISTURBANCE OR LOSS OF SPECIAL-STATUS SPECIES Burrowing Owls Impact Bio-7: Construction-Period Disturbance of Burrowing Owls. Burrowing owls could potentially burrow in grassland habitats and/or use crevices in shoreline riprap as temporary refugia. Due to the marginal nature of habitat on the site, and the current lack of suitable breeding sites in the form of ground squirrel burrows, the OPSP will not result in a significant loss of burrowing owl habitat. Nevertheless, any loss of burrowing owls or fertile eggs, any activities resulting in nest abandonment, or the destruction of occupied burrowing owl burrows would constitute a potentially significant impact under CEQA due to the regional rarity of the species and declining nature of its populations. Although no burrowing owls or ground squirrel burrows were observed on the OPSP area during the November 2009 or September 2010 reconnaissance surveys, burrowing owls could potentially occur on the Phase I site in grassland habitats if ground squirrels are present. There is also some potential for occasional transient owls to use crevices in shoreline riprap as temporary refugia. In the unlikely event that owls were nesting on the site, construction-related disturbance during the breeding season could result in the incidental loss of fertile eggs or nestlings, or otherwise lead to nest abandonment. However, if burrowing owls occur on the site at all, they likely do so as nonbreeding visitors. Because this species live in burrows even during the non-breeding season, they are more likely to take refuge in those burrows rather than flushing in response to disturbance as most birds do, therefore raising the risk of individual owls being crushed in their burrows during construction activities in any season. Mitigation Measures Bio-7a: Pre-construction Burrowing Owl Surveys.Pre-construction surveys for burrowing owls shall be completed in potential habitat in conformance with the California Burrowing Owl Consortium protocol, no more than 30 days prior to the start of construction. If no burrowing owls are located during these surveys, no additional action would be warranted. However, if burrowing owls are located on or immediately adjacent to the site, mitigation measures Bio-7b and Bio-7c shall be implemented. Bio-7b: Buffer Zones.For burrowing owls present during the non-breeding season (generally 1 September to 31 January), a 150-ft buffer zone shall be maintained around the occupied burrow(s) if practicable. If such a buffer is not practicable, then a buffer adequate to avoid injury or mortality of owls shall be maintained, or the birds shall be evicted as described for Mitigation Measures Bio-7c, below. During the breeding season (generally 1 February to 31 August), a 250-ft buffer, within which no new activity shall be permissible, shall be maintained between OPSP activities and occupied burrows. Owls present on site after 1 February shall be assumed to be nesting unless evidence indicates otherwise. This protected buffer area shall remain in effect until 31 August, or based upon monitoring evidence, until the young owls are foraging independently or the nest is no longer active. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 7-28 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Bio-7c: Passive Relocation. If construction will directly impact occupied burrows, eviction of owls should occur outside the nesting season to prevent injury or mortality of individual owls. No burrowing owls shall be evicted from burrows during the nesting season (1 February through 31 August) unless evidence indicates that nesting is not actively occurring (e.g., because the owls have not yet begun nesting early in the season, or because young have already fledged late in the season). Relocation of owls during the non-breeding season shall be performed by a qualified biologist using one-way doors, which should be installed in all burrows within the impact area and left in place for at least two nights. These one- way doors shall then be removed and the burrows backfilled immediately prior to the initiation of grading. With implementation of Mitigation Measures Bio-7a through Bio-7c, impacts related to disturbance of burrowing owls would be reduced to a less-than-significant level. Increased Recreational Disturbance on Wildlife Impact Bio-8: Increased Recreational Disturbance on Wildlife. Recreational demand in the Oyster Point area is expected to increase with the development of the OPSP and such increased use could potentially subject biological resources (both within and outside the OPSP area, such as waterbirds using the edge of San Francisco Bay) to greater disturbance by people walking and biking. However, because there is already a substantial amount of human activity at Oyster Point, the area is already largely habituated to high levels of human activity. Increased use of trails or other areas that are already fairly heavily used by people is thus not expected to reduce the use of such areas by wildlife. Therefore, an increase in recreational users of the Bay Trail and other areas adjacent to wildlife habitat resulting from construction of the OPSP would have a less-than-significant impact on wildlife in these areas. Impacts of Lighting on Terrestrial and Aquatic Animals Impact Bio-9: Increased Lighting Impacts on Wildlife. Lighting in and adjacent to more natural areas on the OPSP area, especially the shoreline along San Francisco Bay, is expected to increase as a result of the OPSP. Artificial lighting has been demonstrated to cause changes in the physiology and behavior of certain animals. However, the OPSP area is already subjected to substantial amounts of artificial night lighting, including night lighting from roads, parking lots, and buildings. As a result, any wildlife currently using the site is habituated to the lighting present within this urban area. The OPSP incorporates guidelines for the design of lighting to minimize light pollution in areas other than those intended to be lit. Therefore, impacts from increased lighting levels on wildlife will be less-than-significant. Artificial lighting has been demonstrated to cause changes in the physiology and behavior of a number of animal taxa; while some animals take advantage of artificial lighting to more easily detect prey at night, or take advantage of prey concentrations attracted to artificial lights, other animals are adversely affected by artificial lighting (Rich and Longcore 2006). Species such as birds and amphibians can become disoriented by changes in lighting, and many species of insects are attracted to light (Longcore and Rich 2004). Reproductive behaviors of some species can be affected by the increased risk of predation caused by increases in lighting, and visual communication between individuals of can be disrupted by lighting (Longcore and Rich 2004). In more remote areas that are not already subjected to urban lighting, an increase in night lighting could disrupt the behavior of animals, potentially increase CHAPTER 7: BIOLOGICAL RESOURCES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 7-29 predation on some nocturnal animals, and result in displacement of the most sensitive species from areas with increased lighting. However, the OPSP area is already subjected to substantial amounts of night lighting, including night lighting from roads, parking lots, and buildings. As a result, any wildlife currently using the site is habituated to the lighting present within this urban area. The OPSP incorporates guidelines for the design of lighting to minimize light pollution in areas other than those intended to be lit. For example, lighting will be directed downward at low cut-off angles to minimize off-site light migration and the OPSP’s contribution to light pollution. Implementation of a lighting plan is included in Mitigation Measure Vis-2a, detailed in Chapter 4 and would further reduce this impact. Because there is already a substantial amount of artificial lighting at Oyster Point, the implementation of these guidelines will prevent the installation of new lighting from substantially increasing lighting levels, and from impacting terrestrial and aquatic species. Therefore, impacts from increased lighting levels on wildlife will be less than significant. Impacts to Migratory Birds from Buildings and Lighting Impact Bio-10: Increased Potential for Bird Strikes. Relative to the height of the existing structures, several of the OPSP’s proposed buildings will project higher, creating new, somewhat larger obstacles along the flight path of migrating and foraging birds. Therefore, the OPSP could result in the creation of a new strike hazard for migrating. Although large-scale injury or mortality of birds due to collisions with buildings is not anticipated, because of the potential for such mortality to occur, the OPSP is considered to have a potentially significant impact to migratory birds. The Study Area is located along the Pacific Flyway for migratory birds, and the juxtaposition of wetland, shoreline, and open water habitats used by birds results in large-scale movements of birds along the edge of San Francisco Bay, both during long-distance movements (such as migration) and during daily movements between roosting and foraging habitats. During spring and fall migratory periods in particular, birders have documented high densities of migrant songbirds using vegetated areas at the edges of San Francisco Bay, and the OPSP area has the potential to support high densities of birds at times during migration. There is thus potential for injury or mortality of birds due to collisions with artificial structures such as buildings as birds engage in such movements. Many birds migrate at night, when it is difficult for them to see structures in their paths. In addition, birds migrating at night are often attracted to sources of artificial light, particularly during periods of inclement weather. Exposure to night lighting can cause alteration of flight paths and can attract birds to the light source (Keyes 2005, Gauthreaux and Belser 2006). As a result, bright lights on buildings can result in bird collisions with the buildings. Even during the day, birds may collide with windows or with tall, glass-covered buildings. Large-scale collisions resulting in mortality of large numbers of birds have been documented in eastern and Midwestern North America (Avery 1979), but it is possible that such mortality could occur in the West as well. Within the OPSP area, there is some potential for birds to collide during daytime and nocturnal flights with structures such as windows of office buildings. Structures currently present along the southern portion of Oyster Point are one to three stories high, while several structures at the northern end of Oyster Point are five stories high. The existing structures at Oyster Point are relatively low, and the exteriors of these buildings have been designed with clear patterns that do not result in extensive areas of reflective surfaces. As a result, most migrating birds would be flying above these buildings, and birds would easily be able to see these buildings because they are not comprised of extensive areas that reflect, and that thus would appear to a bird to be similar to, the sky. Therefore, the risk of bird strikes under existing conditions is expected to be relatively low. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 7-30 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT The tallest new building that will be constructed during Phase I of the OPSP could be 10 stories high. Relative to the height of the existing structures, several of the OPSP’s proposed buildings will project higher, creating new, somewhat larger obstacles along the flight path of migrating and foraging birds. Although all of these buildings are likely to be at a lower height than most migrating birds will be flying, the OPSP would create potential bird strike hazards at elevations that do not currently exist. With structures up to 195 ft tall and windy, often foggy conditions along San Francisco Bay, the risk of collision for birds would increase. Therefore, the OPSP could result in the creation of a new strike hazard for migrating birds that could result in the loss of substantial numbers of birds over the life of the OPSP. Additionally, operating effects associated with the lighting of the buildings can alter the flight patterns of migratory birds and potentially increase bird strike collisions with the tall buildings. Although large-scale injury or mortality of birds due to collisions with buildings has not been reported from the West Coast, depending on the design of the buildings there is some potential for such mortality to occur in the absence of mitigation measures. Because of these potential effects, the OPSP is considered to have a potentially significant impact to migratory birds. Mitigation Measures Bio-10a: Lighting Measures to Reduce Impacts to Birds. During design of any building greater than 100 feet tall, the OPSP Applicant shall consult with a qualified biologist experienced with bird strikes and building/lighting design issues to identify lighting-related measures to minimize the effects of the building’s lighting on birds. Such measures, which may include the following and/or other measures, shall be incorporated into the building’s design and operation. x Use strobe or flashing lights in place of continuously burning lights for obstruction lighting. Use flashing white lights rather than continuous light, red light, or rotating beams. x Install shields onto light sources not necessary for air traffic to direct light towards the ground. x Extinguish all exterior lighting (i.e., rooftop floods, perimeter spots) not required for public safety. x When interior or exterior lights must be left on at night, the operator of the buildings shall examine and adopt alternatives to bright, all-night, floor-wide lighting, which may include: x Installing motion-sensitive lighting. x Using desk lamps and task lighting. x Reprogramming timers. x Use of lower-intensity lighting. x Windows or window treatments that reduce transmission of light out of the building shall be implemented to the extent feasible. Bio-10b: Building Design Measures to Minimize Bird Strike Risk. During design of any building greater than 100 feet tall, the OPSP Applicant shall consult with a qualified biologist experienced with bird strikes and building/lighting design issues to identify measures related to the external appearance of the building to minimize the risk of bird strikes. Such measures, which may include the following and/or other measures, shall be incorporated into the building’s design. CHAPTER 7: BIOLOGICAL RESOURCES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 7-31 x Use non-reflective tinted glass. x Use window films to make windows visible to birds from the outside. x Use external surfaces/designs that “break up” reflective surfaces rather than having large, uninterrupted areas of surfaces that reflect, and thus may not appear noticeably different (to a bird) from, the sky. Implementation of the building design and lighting measures presented in mitigation measures Bio-10a and Bio-10b will avoid and minimize impacts to migrating and foraging birds as a result of increased bird strikes and the impact will be reduced to a less-than-significant level. TREES PROTECTED BY THE CITY’S TREE PROTECTION ORDINANCE Impact Bio-11: Protected Tree Removal. One or more mature blue gum trees within the ornamental woodland habitat may satisfy size requirements for a “protected tree” under the City of South San Francisco’s Tree Protection Ordinance. Trees are considered protected if they are 48 inches or more at 54 inches above the natural grade. These trees, while providing some wildlife habitat, are non-native invasive trees that severely degrade natural habitats. Eucalyptus species outcompete native species and produce leaf litter that reduces the diversity and cover, and can alter fire regimes within the associated woodland understory. If any of these trees are found to be of sufficient size to be considered protected under the City’s ordinance, a permit will be required for their removal. However, due to the low habitat functions and values provided by these trees, their loss, and the loss of potential nesting, roosting, and foraging opportunities associated with them, this is considered a less-than-significant impact. IMPACTS OF IN-WATER CONSTRUCTION In-water construction is not proposed as a part of Phase I of the OPSP, but could be included in the form of removal and replacement of piers in the Oyster Point Marina during future phases of OPSP development. If such in-water construction were to take place, it could result in the following additional impacts. Essential Fish Habitat and Special-Status Fish Impact Bio-12: In-Water Construction Impacts on Essential Fish Habitat. Special-status fish species that occur in the OPSP vicinity and could potentially be impacted by in- water construction activities are the southern green sturgeon, the Central California Coast steelhead, and the longfin smelt. Habitat for occasional dispersing individuals of all three species is similarly located in open waters and estuarine habitats of the San Francisco Bay along the boundaries of the OPSP area. This is a potentially significant impact. The tidal aquatic habitats adjacent to the OPSP area are considered Essential Fish Habitat by the NMFS. If programmatic OPSP elements include construction activities in the waters of the Bay, such activities could adversely impact Essential Fish Habitat in the OPSP area Mitigation Measure Bio-12: Measures to Reduce Impacts on Essential Fish Habitat. The following mitigation measures, adapted from Amendment 11 of the West Coast Groundfish DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 7-32 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Plan (PFMC 2006) and Appendix A of the Pacific Coast Salmon Plan (PFMC 2003), shall be implemented during in-water construction activities unless modified by the federal permitting agencies (NMFS or USACE). Avoidance of Salmonid Migration Periods. In-water work when juvenile salmonids are moving through the Bay on the way to the open ocean or when groundfish and prey species could be directly impacted shall be avoided. Because steelhead are potentially present, the allowed dredge window for this area of the San Francisco Bay is June 1 through November 30. All in-water construction shall occur during this window. If completion of in-water work within this period is not feasible due to scheduling issues, new timing guidelines shall be established and submitted to the NMFS and CDFG for review and approval. Worker Training. Personnel involved in in-water construction and deconstruction activities shall be trained by a qualified biologist in the importance of the marine environment to special-status fish, and birds and the environmental protection measures put in place to prevent impacts to these species, their habitats, and EFH. The training shall include, at a minimum, the following: 1.A review of the special-status fish and sensitive habitats that could be found in work areas 2.Measures to avoid and minimize adverse effects to special-status fish, birds, their habitats, and EFH 3.A review of all conditions and requirements of environmental permits, reports, and plans (i.e., USACE permits) Avoidance of Areas of Wetland and Aquatic Vegetation. All construction equipment used in conjunction with in-water work (pipelines, barges, cranes, etc.) shall avoid wetlands, marshes, and areas of sub-aquatic vegetation (including eelgrass beds). Mitigation Measure Bio-3a would also reduce impact Bio-12 through implementation of Best Management Practices for water quality during construction. Implementation of mitigation measures Bio-12 and Bio-3a would reduce impacts to essential fish habitat to a less-than-significant level through avoidance of salmonid migration periods and wetland and aquatic vegetation, appropriate worker training, and implementation of best management practices for water quality during construction. Pile-Driving Impacts to Fish and Marine Mammals Impact Bio-13: Percussive In-Water Construction Noise and Special-Status Fish. If in-water construction is undertaken and includes jackhammering, pile-driving or other in- water percussive activities, pressure waves could cause negative behavioral, psychological and physiological effects that could disturb, injure or kill special- status fish or marine mammals. Due to the number of fish that could be present near in-water construction areas, the potential presence of special-status fish, and the sensitivity of marine mammals such as harbor seals and California sea lions, such impacts are potentially significant. CHAPTER 7: BIOLOGICAL RESOURCES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 7-33 If programmatic OPSP elements include construction activities in the waters of the Bay, individuals of special-status fish species could suffer injury or mortality due to construction activities including percussive noise due to jackhammering, pile-driving, or other in-water percussive activities. Pile- driving outside of the water will not result in pressure waves sufficient to result in injury or mortality of fish or marine mammals. This discussion of pile-driving impacts and mitigation pertains only to pile- driving within the water. For further information related to pile-driving and vibration, see Chapter 12: Noise. The in-water pressure wave, if of sufficient magnitude, can injure or kill fish. Pressure waves have an actual force associated with them and the stronger the force, the more likely they are to damage sensitive tissues in aquatic species. Pressure waves interact with fish in the water column, causing behavioral and physiological effect such as avoidance, stress, temporary loss of hearing, rupture of swim bladders (air pockets that are used for buoyancy), the formation of bubbles in the circulatory system and corresponding rupturing of blood vessels, traumatic brain injuries, and death. Current criteria indicate that sound levels of 183 decibels can injure or kill fish (Fisheries Hydroacoustic Working Group 2008). Marine mammals, which have sensitive hearing, can also easily be disturbed by sound-generated pressure waves, although effects from OPSP activities would be unlikely to cause injury or mortality of these species. Mitigation Measures Bio-13a: Incorporation of Design Considerations that Minimize the Need for Percussive Construction Techniques. If programmatic OPSP elements after the Phase I Project include in-water construction of structures that require percussive techniques, structure design shall adhere to the following principles to the greatest extent practicable: 1.Engineer structures to use fewer or smaller piles, where feasible, and preferably, solid piles 2.Design structures that can be installed in a short period of time (i.e., during periods of slack tide when fish movements are lower). 3.The City, with consultation from a qualified biologist who is familiar with marine biology, shall review the final plan design to ensure that these design requirements have been incorporated into the plan. Bio-13b: Utilization of Construction Tools and Techniques that Minimize Percussive Noise.If programmatic OPSP elements include construction of structures that require percussive techniques, construction activities shall employ the following techniques to the greatest extent practicable. 1.Drive piles with a vibratory device instead of an impact hammer if feasible, and use a cushioning block between the hammer and the pile. 2.Restrict driving of steel piles to the June 1 to November 30 work window, or as otherwise recommended by the NMFS (driving of concrete piles would not be subject to this condition). 3.If steel piles must be driven with an impact hammer, an air curtain shall be installed to disrupt sound wave propagation, or the area around the piles being driven shall be dewatered using a coffer dam. The goal of either measure is to disrupt the sound wave as it moves from water into air. 4.If an air curtain is used, a qualified biologist shall monitor pile driving to ensure that the air curtain is functioning properly and OPSP-generated sound DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 7-34 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT waves do not exceed the threshold of 180183-decibels generating 1 micropascal (as established by NMFS guidelinesthe Fisheries Hydroacoustic Working Group; 2008). This shall require monitoring of in-water sound waves during pile driving. 5.Use of fewer piles, or smaller piles, or a different type of pile, with hollow steel piles appearing to create the most impact at a given size 6.Driving piles when species of concern are absent 7.Use of a vibratory hammer rather than an impact hammer 8.Use of a cushioning block between hammer and pile 9.Use of a confined or unconfined air bubble curtain; and 10.Driving piles during periods of reduced currents Implementation of mitigation measures Bio-13a and Bio-13b would reduce impacts to special-status fish and marine mammal species due to percussive in-water construction activities to less-than- significant levels by minimizing percussive noise through utilization of appropriate design and construction techniques. Impacts to Olympia Oyster Beds Impact Bio-14: In-Water Construction Disturbance of Olympia Oyster Beds. There is a known population of Olympia oysters at Oyster Point. In-water construction activities, including activities at the marina and along the shoreline, could potentially impact oysters through the removal of substrate supporting oysters, smothering of oyster beds with fill, or degradation of water quality. Such oysters, including their larvae, provide food, refugia, and attachment sites for a number of aquatic organisms and filter nutrients and pollutants from the water. As a result, these oysters perform a valuable function to the Bay ecosystem, and impacts to oysters from in-water construction activities are potentially significant. Mitigation Measures Bio-14a: Avoidance of Suitable Oyster Habitat. To the greatest extent practicable, OPSP activities shall avoid removing or disturbing riprap and other rocky substrates that serve as suitable oyster habitat. If impacts to oysters and their habitat are unavoidable, measures Bio-14b and Bio-14c shall be implemented. Bio-14b: Native Oyster Surveys. A detailed survey for native oysters shall be conducted in all suitable substrates within the OPSP area. This survey shall be conducted by a qualified oyster biologist at low tides that expose the maximum amount of substrate possible. Surveys can be conducted at any time of year, but late summer and early fall are optimal because newly settled oysters are detectable. This survey shall occur before any construction within aquatic habitats takes place to establish a baseline condition. If few or no oysters are observed on hard substrates that would remain in place after construction, no further mitigation is required. CHAPTER 7: BIOLOGICAL RESOURCES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 7-35 Bio-14c: Replacement of Suitable Oyster Habitat. If more than 100 oysters would be removed or are in areas where construction-generated sediment could settle out onto the oysters, compensatory mitigation shall be provided by the OPSP Applicant at a minimum 1:1 ratio. The OPSP Applicant shall retain a qualified oyster biologist to develop an Oyster Restoration Plan that shall be reviewed and approved by the City. This Plan shall include site selection, substrate installation, and monitoring procedures, and include the following components (unless otherwise modified by NMFS): 1.A suitable site for installation of replacement substrate would be one with adequate daily tidal flow, a location that would not be affected by maintenance dredging or other routine marina maintenance activities, and one that is lacking in appropriate settlement substrate. A location outside of the breakwaters or in association with any eelgrass mitigation sites would be appropriate. 2.Although oysters may settle on a variety of materials, the most appropriate for restoration purposes is oyster shell. This is typically installed by placing the shell into mesh bags that can then be placed in piles on the seafloor of the mitigation site. Enough shell shall be installed under the guidance of a qualified oyster biologist to make up for the loss attributable to the OPSP. Mitigation shall occur after construction of all in-water elements of the OPSP. 3.The restoration site shall be monitored on a regular basis by a qualified oyster biologist for a minimum of two years, or until success criteria are achieved if they are not achieved within two years. Monitoring shall involve routine checks (bi-monthly during the winter and monthly during the spring and summer) to evaluate settlement, growth, and survival on the mitigation site. Success shall be determined to have been achieved when settlement and survival rates for oysters are not statistically significantly different between the mitigation site and the populations being impacted. Mitigation Measure Bio-3a would also reduce impact Bio-14 through implementation of Best Management Practices for water quality during construction. With implementation of mitigation measures Bio-14a through Bio-14c and Bio-3a, the impacts to related to in-water construction disturbance of Olympia oyster beds would be reduced to a less-than- significant level by implementing Best Management Practices for water quality, identifying oyster populations, avoiding suitable habitat where possible and replacement of suitable habitat when avoidance is not feasible. Impacts to Eelgrass Beds Impact Bio-15: Increased Turbidity During In-Water Construction and Eelgrass Beds. In- water construction activities that result in increased turbidity could potentially result in adverse effects to eelgrass by covering eelgrass with sediment. Because eelgrass beds provide nursery habitat for a variety of fish species, they are very important to the Bay ecosystem, and impacts to eelgrass beds are thus potentially significant. Although no eelgrass beds or patches have been mapped closer than 3 mi from the OPSP area, the NMFS (2010) considers portions of Oyster Point to offer suitable eelgrass habitat, and there is some evidence that eelgrass populations in the Bay are expanding (Merkel & Associates 2004). Thus, we DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 7-36 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT cannot rule out the possibility that eelgrass patches or beds have become established, or will become established prior to the initiation of programmatic activities, in or near the OPSP area. Mitigation Measures Bio-15a: Water Quality Best Management Practices for Eelgrass. In addition to the water quality BMPs described above in Measure Bio-3a, the following BMPs shall minimize impacts to any eelgrass beds in the OPSP area. 1.Conduct all in-water work during periods of eelgrass dormancy (November 1- March 31) [Note: the majority of this period conflicts with the period during which in-water activities should not occur to avoid impacts to salmonids; only the period November 1-30 would avoid impacts during sensitive periods for both taxa.] 2.Install sediment curtains around the worksite to minimize sediment transport If these BMPs are not feasible, or if OPSP activities will occur in aquatic areas outside of the marina, mitigation measures 15b and 15c shall be undertaken. Bio-15b: Eelgrass Survey. Prior to any construction activities in aquatic habitats, a survey for eelgrass beds or patches shall be conducted within 750 ft of expected aquatic construction activities. The survey shall be conducted by a biologist(s) familiar with eelgrass identification and ecology and approved by NMFS to conduct such a survey. Survey methods shall employ either SCUBA or sufficient grab samples to ensure that the bottom was adequately inventoried. The survey shall occur between August and October and collect data on eelgrass distribution, density, and depth of occurrence for the survey areas. The edges of any eelgrass beds or patches shall be mapped. At the conclusion of the survey a report shall be prepared documenting the survey methods, results, and eelgrass distribution, if any, within the survey area. This report shall be submitted to NMFS for approval. If OPSP activities can be adjusted so that no direct impacts to eelgrass beds would occur, no further mitigation would be required. If direct impacts to eelgrass beds cannot be avoided, the following measures shall be implemented. Bio-15c: Compensatory Eelgrass Mitigation. If direct impacts to eelgrass beds cannot be avoided, compensatory mitigation shall be provided in conformance with the Southern California Eelgrass Mitigation Policy. Mitigation shall entail the replacement of impacted eelgrass at a 3:1 (mitigation: impact) ratio on an acreage basis, based on the eelgrass mapping described in mitigation measure 8B above, and detailed designs of the feature(s) that would impact eelgrass beds. Such mitigation could occur either off site or on site (NMFS 2005b). Off-site mitigation could be achieved through distribution of a sufficient amount of funding to allow restoration or enhancement of eelgrass beds at another location in the Bay. If this option is selected, all funds shall be distributed to the appropriate state or federal agency or restoration-focused non-governmental agency (i.e., CDFG restoration fund, California Coastal Conservancy, Save the Bay, etc). The OPSP Applicant shall provide written evidence to the City that either a) compensation has been established through the purchase of a sufficient number of mitigation credits to satisfy the mitigation acreage requirements of the OPSP activity, or funds sufficient for the restoration of the mitigation acreage requirements of the OPSP activity have been paid. These funds shall be applied only to eelgrass restoration within the Bay. CHAPTER 7: BIOLOGICAL RESOURCES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 7-37 If on-site mitigation is selected as the appropriate option, the OPSP Applicant shall retain a qualified biologist familiar with eelgrass ecology to prepare and implement a detailed Eelgrass Mitigation Plan. Unless otherwise directed by NMFS, the Eelgrass Mitigation Plan shall follow the basic outline and contain all the components required of the Southern California Eelgrass Mitigation Policy (as revised in 2005), including: identification of the mitigation need, site, transplant methodology, mitigation extent (typically 3:1 on an acreage basis), monitoring protocols (including frequency, staffing, reviewing agencies, duration, etc), and success criteria. A draft Eelgrass Mitigation Plan shall be submitted to NMFS, for its review and approval prior to implementation, with a copy to the City. Once the plan has been approved, it shall be implemented in the following appropriate season for transplantation. Restored eelgrass beds shall be monitored for success over a 5-year period. Mitigation Measure Bio-3a would also reduce impact Bio-15 through implementation of Best Management Practices for water quality during construction. With implementation of mitigation measures Bio-15a through Bio-15c and Bio-3a, the impacts to related to in-water construction disturbance of eelgrass beds would be reduced to a less-than- significant level by implementing Best Management Practices for water quality, additional Best Management Practices for eelgrass, and if necessary, conducting eelgrass surveys and replacement when avoidance is not feasible. HABITAT CONSERVATION PLAN OR NATURAL COMMUNITY CONSERVATION PLAN The OPSP area is not within an area covered by a Habitat Conservation Plan (HCP) or Natural Community Conservation Plan (NCCP), or proposed for salt marsh restoration. The proposed OPSP would not conflict with other wildlife protection or enhancement programs that includes Alameda County, such as the Alameda County Wildlife Friendly Pond Restoration Program, a U.S. Fish & Wildlife Service “Safe Harbor Agreement” for the enhancement of the California red-legged frog and California tiger salamander. There are no ponds on the OPSP area and no habitat for red-legged frogs or tiger salamanders (no impact). CUMULATIVE BIOLOGICAL RESOURCES IMPACTS Cumulative impacts arise from a concatenation of impacts from past, current, and reasonably foreseeable future projects in the region. With implementation of the mitigation measures above, no significant impacts are expected as a result of project-level or program-level implementation of the OPSP. The proposed OPSP will not result in a cumulatively considerable contribution to cumulative impacts to biological resources. With the exception of isolated protected open spaces, the OPSP vicinity is largely built up, and few areas for new development remain. However, infill development and redevelopment of existing areas are likely to occur in the OPSP vicinity. For example, the Candlestick Point-Hunters Point Shipyard redevelopment project is proposed just north of the OPSP area (City of San Francisco 2010). All of these Projects are each expected to complete (or have completed) their own separate CEQA reviews, and to address any potential impacts therein by mitigating them to a less than significant level. OPSP impacts will result primarily from the loss or modification of regionally abundant terrestrial habitats and the associated modification of wildlife communities dominated by regionally abundant DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 7-38 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT species. Due to the abundance of these species and habitat types regionally, the OPSP will not contribute to cumulative impacts on these resources. Wetland and aquatic habitats of San Francisco Bay, which could be impacted by the OPSP, are of particular ecological importance, have undergone more substantial modification by human activities, and are less extensive regionally than the upland habitats that will be impacted by the OPSP. However, not only will the OPSP mitigate its contribution to cumulative impacts to these resources, but restoration projects such as the South Bay Salt Ponds Restoration Project and others throughout San Francisco Bay will enhance and restore Bay habitats and animal communities in the coming decades, thus helping to reverse cumulative impacts on these resources. The OPSP area does not contain areas that would be considered federally protected wetlands, riparian habitat or other sensitive natural communities, does not appear to constitute a major movement corridor for native wildlife, and does not conflict with any conservations plans or local ordinances. While the OPSP has the potential to impact the special status species, burrowing owl, a mitigation measure requiring a preconstruction survey that would detect use of the site by these owls and implementation of avoidance measures if found would reduce the impact to less than significant and would not contribute to cumulative impacts (no impact). OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 8-1 8 CULTURAL RESOURCES INTRODUCTION This section describes existing cultural resources at the OPSP site and describes whether implementation of the OPSP and Phase I Project would cause a substantial adverse change in the significance of a historic or archaeological resource (as defined in Section 106 of the National Historic Preservation Act and Section 15064.5 of the CEQA Guidelines), directly or indirectly destroy a unique paleontological resource or site or unique geologic feature, or result in the disturbance of any human remains, including those interred outside of formal cemeteries. Preparation of this section used data from the South San Francisco East of 101 Area Plan and South San Francisco Ferry Terminal EIR (prepared by EIP, 2006). ENVIRONMENTAL SETTING ARCHAEOLOGY Prehistoric and Ethnographic Context At the time of initial contact between European explorers and the Native Californians, the area that is now San Francisco was inhabited by a people who were of Penutian linguistic stock and who spoke the Ramaytush language. These people, referred to as Costanoan, reaped the benefit of living in a bountiful, temperate environment. Abundant marine and terrestrial resources made both agriculture and animal husbandry unnecessary. Evidence of the success of their hunter/gatherer subsistence strategy may be seen in the number of flourishing village sites known to have existed at the time of contact with the Spanish. The detritus of these sites was found in numerous locations around the shoreline of San Francisco Bay in the form of shellmounds—large accumulations of shell, ash, human artifacts, and occasionally human remains. With the influx of European settlers in the mid-nineteenth century, most of these sites were destroyed or covered by buildings and roads at numerous locations around the bay shoreline, including the OPSP site. Additionally, the OPSP site is located along the southwestern shoreline of the San Francisco Bay. Gold rush-era silt accumulation and historic settlement (e.g., landfills) effectively filled in hundreds acres of the original bay shoreline. Portions of the OPSP site is located on such fill, and as a result the original shoreline would have been located approximately 2,000 feet west and 3,000 feet south of the OPSP area. Estuary and marsh locales along the former bay shoreline would have offered abundant food resources to prehistoric human population. The term Costanoan is derived from the Spanish word Costaños, or "coast people," but its application as a means of identifying this population is based in linguistics. Costanoan actually designates a family of eight languages. Of these, Ramaytush was the language spoken by the estimated 1,400 people who occupied the area now designated as San Francisco and San Mateo counties. Tribal groups occupying DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 8-2 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT the area from the Pacific Coast to the Diablo Range and from San Francisco to Point Sur spoke the other seven languages of the Costanoan family. Modern descendants of the Costanoan prefer to be known as Ohlone and formed a corporate entity in 1971, the Ohlone Indian Tribe. They are named after the Oljón tribal group, which occupied the San Gregorio watershed in San Mateo County. On the basis of linguistic evidence, it has been suggested that the ancestors of the Ohlone arrived in the San Francisco Bay area about 500 A.D. from the Sacramento-San Joaquin Delta region. Extended families lived in domed structures thatched with tule, grass, wild alfalfa, ferns or carrizo. Semi- subterranean sweathouses were built into pits excavated in stream banks and covered with a structure against the bank. The tule raft, propelled by double-bladed paddles were used to navigate across San Francisco Bay. The Ramaytush usually cremated a corpse immediately upon death but, if there were no relatives to gather wood for the funeral pyre, interment occurred. Mortuary goods were all or most of the personal belongings of the deceased. Mussels were an important staple in the Costanoan diet as were acorns of the coast live oak, valley oak, tanbark oak and California black oak. Seeds and berries, roots, grasses, and the meat of deer, elk, grizzly, sea lion, rabbit, and squirrel also contributed to the Costanoan diet. Careful management of the land through controlled burning served to insure a plentiful and reliable source of all these foods. The arrival of the Spanish in the San Francisco Bay Area in 1775 led to the rapid demise of native California populations. Diseases, declining birth rates, and the effects of the mission system served to eradicate the aboriginal life ways (which are currently experiencing resurgence among Ohlone descendants). Brought into the missions, the surviving Costanoan along with former neighboring groups of Esselen, Yokuts, and Miwok were transformed from hunters and gatherers into agricultural laborers. With abandonment of the mission system and Mexican takeover in the 1840s, numerous ranchos were established. Generally, the few native Californians who remained were then forced, by necessity, to work on the ranchos. HISTORIC BACKGROUND History of the OPSP Site and Vicinity The OPSP site is located on the San Mateo Peninsula, a landform that divides the Pacific Ocean from the southern San Francisco Bay, and connects the City of San Francisco with the Santa Clara Valley. The OPSP site is located within the historic boundaries of Rancho Buri Buri, which was first established as grazing land for Mission Dolores and the Presidio of San Francisco. Although ranchos on the Peninsula were generally smaller than those established elsewhere in the Bay Area, the 15,000 acres that made up Buri Buri extended from the San Bruno hills south into modern-day Burlingame, and from the San Andreas Valley east to the shore of San Francisco Bay. By 1810, a successful cattle operation was being run within its boundaries. In October 1827, Sublieutenant José Antonio Sánchez, who was stationed at the Presidio, was granted permission by Mexican governor José María de Echeandía to occupy the rancho for “grazing and agricultural purposes”. With the help of his 10 children and local Indian laborers, Sánchez worked the land from the time it was granted to him until his death in 1843. Upon his death, the rancho lands were divided between his children. In the decade after Sánchez’s death, settlement patterns throughout California changed dramatically. With the discovery of gold in 1849, the once isolated California frontier was soon awash in immigrants from all corners of the world. California’s 1848 population of less than 14,000 (exclusive of Native Californians) increased to 224,000 in four years. By 1850, California had gained statehood and became inextricably linked to the markets and economic forces of the rest of the United States. In the transition, Rancho Buri Buri had become extremely valuable land, not only because it afforded access to a growing transportation network, but because of its proximity to the City of San Francisco the center of CHAPTER 8: CULTURAL RESOURCES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 8-3 regional commerce and cultural activity. In 1872, the heirs to Rancho Buri Buri were forced to sell their land to pay for the high cost of property taxes, legal fees, and loans. The new owners of Rancho Buri Buri included prominent men such as D. O. Mills, Ansel Easton and Charles Lux. Just two years after Charles Lux consolidated the Rancho Buri Buri property, he formed a permanent partnership with fellow San Francisco butcher and entrepreneur Henry Miller. The two worked together to build one of the most powerful cattle businesses in nineteenth-century California. The prime grazing land of Rancho Buri Buri was ideal for holding cattle prior to slaughter, and Miller and Lux not only purchased more land within the former grant, but leased additional land on the Peninsula for grazing purposes. Miller and Lux quickly acquired other rancho properties, and by the end of the 1860s they owned over 300,000 acres of grazing land spread throughout the fertile San Joaquin Valley and the ranchos just east of Monterey Bay. They would use their vast holdings to supply beef to the growing San Francisco market. The San Jose Road served as their cattle trail during the 1860s and the San Francisco and San Jose Railroad (completed in 1866) followed the same route. Although their holdings were vast, Rancho Buri Buri was particularly important because of its proximity to the population center of San Francisco. When Charles Lux died, his wife Miranda sold his property in South San Francisco to Gustavus Swift, who represented the American Cattle Trust of Chicago. In the early 1890s the American Cattle Trust was one of the nation’s most powerful business conglomerate. The Cattle Trust formed the South San Francisco Land & Improvement Company in 1891 and created the Western Meat Company, a meatpacking firm. The South San Francisco Land & Improvement Co. began promoting the town of South San Francisco and the Western Meat Company was the first of many industrial concerns to be located at Point San Bruno. The Western Meat Company was quickly able to underbid the merchants of San Francisco’s Butchertown, and a struggle for control of San Francisco’s profitable meatpacking and processing industry escalated in the following years. The standoff was finally resolved when the 1906 earthquake almost completely destroyed the Butchertown facilities, which had been built on piers over San Francisco’s water lots. In addition to increasing the power of South San Francisco’s meatpacking facilities, the earthquake encouraged settlement south of San Francisco, as refugees fled the damage left by the powerful earthquake and fire. Propelled by the South San Francisco Land & Improvement Co., and with a population of just 1,989 people, South San Francisco incorporated in 1908. The 1910 Sanborn map reveals that Point San Bruno was home to a host of industries by that time, including several steel companies. The South San Francisco Belt Railroad had been built to service the industries in the easternmost portion of town and connected their goods and services to the Southern Pacific’s main line. By the time of the 1925 Sanborn mapping, those industries had grown to include other steel, smelting, refining, packing, and milling companies as well as a U.S. Naval Radio Station. The industries located in South San Francisco focused on wartime production during both world wars. The Shaw Batcher Co. shipyards (located at what would become 1050 Oyster Point Blvd.) built ships at the Oyster Point Channel between 1914 and 1918 to help fulfill World War I naval requirements. Shaw Batcher was purchased by Western Pipe and Steel, and between 1940 and 1945 they built 45 ships in 48 months for the Maritime Commission during World War II. The expansion of the ship building industry was part of a widespread boom in the Bay Area that brought an influx of residents. The 1950s saw the construction of large housing developments to accommodate the growing community; and the wartime shipbuilding activities contributed to the infrastructure that allowed South San Francisco to become an important twentieth-century port. In addition to increased housing, the 1950s also ushered in an era of land reclamation. Unused marshland, such as portions of the current OPSP site, was made available for industrial development. Before reclamation, the eastern portion of the landfill on the OPSP site was characterized by Bay mud, while the upland western portion consisted of soil overlying bedrock. The landfill was in operation DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 8-4 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT from 1956 to 1970 and was operated by the South San Francisco Scavenger Company, who leased the site from the City of South San Francisco. The landfill was used primarily for the disposal of solid wastes. The landfill began to receive liquid industrial waste in 1961. Liquid waste was placed into sumps constructed within the fill. In addition, Bay Mud berms were constructed in 1961, 1962, and 1964 to help contain waste. Waste disposal resulted in the extension of the shoreline approximately 3,000 feet east of the original shoreline. With the landfill still in operation, the Marina was constructed in 1962. In 1963, plans for a 600-acre industrial park adjacent to the Marina were announced. With comprehensive planning and modern facilities, the industrial park attracted light industry to the area. Since 1977, the Marina has been managed by the San Mateo County Harbor District. The Marina was expanded in 1978, the year after major landfill activities ceased. Site closure activities included compaction of the fill and placement of a 2-foot layer of low permeability soil on top of the fill. Today the Marina is a recreation destination within South San Francisco with boat launching facilities, a fishing pier, and a large park with hiking trails and picnic facilities. Possible Shipwreck in the Vicinity The California Shipwreck Database maintained by the California State Lands Commission (CSLC) contains one historic shipwreck entry within the vicinity of the OPSP site. The database entry was based on a reference in California Shipwrecks: Footsteps in the Sea, which has subsequently been found to be notoriously inaccurate. The entry in the CSLC Shipwreck Inventory lists the Echo, a sloop that reportedly foundered and sank in San Mateo County on January 15, 1879, in San Francisco Bay “between Redwood City and San Francisco.” In the List of Merchant Vessels of the United States for the years 1874, 1876, and 1877 (1878 not available), the Echo (vessel #8002) is listed consistently as a 27.59-ton sloop home ported in San Francisco. The sloop is not listed in Merchant Vessels in subsequent years, which lends some credibility to the date of loss provided in California Shipwrecks: Footsteps in the Sea (and the CSLC database). The Echo does not appear in the Lloyd’s Register of British and Foreign Shipping, American Lloyd’s Universal, or the Record of American and Foreign Shipping during that time period. REGULATORY SETTING CALIFORNIA REGISTER OF HISTORIC RESOURCES In considering impact significance under CEQA, the significance of the resource itself must first be determined. At the state level, consideration of significance as an “important archaeological resource” is measured by cultural resource provisions considered under CEQA Sections 15064.5 and 15126.4, and the draft criteria regarding resource eligibility for listing on the California Register of Historic Resources (CRHR). Generally under CEQA, a historical resource is considered significant if it meets the criteria for listing on the CRHR. These criteria are set forth in CEQA Section 15064.5, and defined as any historical resource that: (a) Is associated with events that have made a significant contribution to the broad patterns of California’s history and cultural heritage; (b) Is associated with lives of persons important in our past; (c) Embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of an important creative individual, or possesses high artistic values; or (d) Has yielded, or may be likely to yield, information important in prehistory or history. CHAPTER 8: CULTURAL RESOURCES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 8-5 Section 15064.5 of CEQA also assigns special importance to human remains and specifies procedures to be used when Native American remains are discovered. These procedures are detailed under Public Resources Code (PRC) Section 5097.98. Impacts to “unique archaeological resources” and “unique paleontological resources” are also considered under CEQA, as described under PRC Section 21083.2. A unique archaeological resource is an archaeological artifact, object, or site about which it can be clearly demonstrated that without merely adding to the current body of knowledge there is a high probability that it meets one of the following criteria: (a) The archaeological artifact, object, or site contains information needed to answer important scientific questions, and there is a demonstrable public interest in that information; (b) The archaeological artifact, object, or site has a special and particular quality, such as being the oldest of its type or the best available example of its type; or (c) The archaeological artifact, object, or site is directly associated with a scientifically recognized important prehistoric or historic event or person. A non-unique archaeological resource is an archaeological artifact, object, or site that does not meet the above criteria. Impacts to non-unique archaeological resources and resources that do not qualify for listing on the CRHR receive no further consideration under CEQA. IMPACTS AND MITIGATION MEASURES CRITERIA OF IMPACT SIGNIFICANCE Under the CEQA Guidelines, Appendix G – Environmental Checklist Form, a significant impact will occur if the proposed OPSP would: 1.Cause a substantial adverse change in the significance of a historical resources as defined in CEQA Guidelines Section 15064.5; 2.Cause a substantial adverse change in the significance of an archaeological resource pursuant to CEQA Guidelines Section 15064.5; 3.Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature; or 4.Disturb any human remains, including those interred outside of formal cemeteries. DISTURBANCE OF CULTURAL RESOURCES Impact Culture-1: Disturbance of Unidentified Paleontological Resources, Archaeological Resources or Human Remains. During earth-moving activities at the OPSP site, it is possible that unidentified paleontological resources, archaeological resources or human remains could be uncovered and disturbed. As discussed under Environmental Setting, above, a possible shipwreck may exist offshore of the OPSP site, however, the potential in-water activities associated with the OPSP consisting of the possible removal and replacement of two docks would be limited to the existing navigation channel within the Marina. Furthermore, the original shoreline of San Francisco Bay was situated DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 8-6 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT approximately 2000 feet west and 3000 feet south of the OPSP site. Consequently, there is little likelihood that cultural deposits associated with prehistoric occupation or utilization of the OPSP site (such as those associated with a shipwreck) will be encountered in the area to undergo in-water construction. In addition, any historic materials that may have been located within potential in-water construction area, such as shipwreck remains or cultural material discarded into the near shore waters, have long since been destroyed, as the navigation channel has been routinely dredged for maintenance purposes for a considerable length of time. None of the structures on OPSP site are of historic age (over 50 years) or classified as historical resources and no archaeological or paleontological resources have been identified at the OPSP site. As a previously-disturbed site, it is unlikely buried resources (paleontological, archeological or human remains) exist on the OPSP site. However, excavation for grading and building foundations has the potential to uncover previously unknown resources. While development of the OPSP site as proposed would not be expected to result in any substantial adverse effects on any cultural resource, any excavation activity carries the possibility that previously unidentified archaeological resources, paleontological resources or human remains could be uncovered. This potential impact can be mitigated though implementation of the following standard measures. Mitigation Measures Culture-1a: Halt Construction Activity, Evaluate Find and Implement Mitigation. In the event that any previously unidentified paleontological or archaeological resources are uncovered during site preparation, excavation or other construction activity, all such activity shall cease until these resources have been evaluated by a qualified paleontologist or archaeologist and specific mitigation measures can be implemented to protect these resources. Culture-1b: Halt Construction Activity, Evaluate Find and Take Appropriate Action in Coordination with Native American Heritage Commission. In the event that any human remains are uncovered during site preparation, excavation or other construction activity, all such activity shall cease until these resources have been evaluated by the County Coroner, and appropriate action taken in coordination with the Native American Heritage Commission. Incorporation of mitigation measures Culture-1a and Culture-1b will reduce the impacts associated with possible disturbance of unidentified paleontological resources, archaeological resources or unidentified human remains at the OPSP site to a level of less than significant.

REGULATORY SETTING CITY OF SOUTH SAN FRANCISCO HAZARD MITIGATION PLAN The City of South San Francisco has adopted the Association of Bay Area Governments Local Hazard Mitigation Plan as the Hazard Mitigation Plan (HMP) for the City by resolution 65-2006, on August 16, 2006. The HMP has been designed to identify the areas where people or structures may have higher vulnerability to earthquakes, flood, wildland fires, and other natural hazards. The plan identifies policies and actions that may be implemented by the City to reduce the potential for loss of life and property damage in these areas based on an analysis of the frequency of earthquakes, floods, wildland fires and landslides in terms of frequency, intensity, location, history, and damage effects. The Plan serves as a guide for decision-makers as they commit resources to reduce the effects of natural hazards. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 9-2 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT CITY OF SOUTH SAN FRANCISCO GENERAL PLAN UPDATE EIR The General Plan Update Health and Safety Element includes a section on Geological and Seismic Hazards. This section identifies geotechnical and geologic impacts to the general City of South San Francisco area. The most recent General Plan update was completed in October 1999. EAST OF 101 AREA PLAN The 1999 General Plan update also includes a summary of the East of 101 area plan, providing specific policies for the area located east of U.S. Highway 101. ALQUIST-PRIOLO EARTHQUAKE FAULT ZONING ACT The California Alquist-Priolo Earthquake Fault Zoning Act of 1972 requires the mapping and zoning of active faults within the State of California. Under the act, development within zones of active fault displacement is restricted for structures intended for human occupancy. Any development site located within an Earthquake Fault Zone Boundary as delineated on State maps must be studied to determine if an active fault crosses the subject parcel. Setbacks from active faults are required under the Act. There is an Alquist-Priolo Earthquake Fault Zone Map for the South San Francisco Quadrangle, in which the Project site is located. CALIFORNIA SEISMIC HAZARDS MAPPING ACT The California Seismic Hazards Mapping Act of 1990 (California Public Resources Code Sections 2690-2699.6) addresses seismic hazards other than surface rupture, such as liquefaction and seismically induced landslides. The Seismic Hazards Mapping Act specifies that the lead agency for a project may withhold development permits until geologic or soils investigations are conducted for specific sites and mitigation measures are incorporated into plans to reduce hazards associated with seismicity and unstable soils. The State of California does not currently have a Seismic Hazard Map for the South San Francisco Quadrangle, in which the Project is located. However, the Seismic Hazard Map Home Page indicates that mapping for the southern part of the South San Francisco Quadrangle is currently under preparation.1 This map may be completed in the near future. CALIFORNIA BUILDING CODE (2010) The California Building Code (CBC) was developed to incorporate modifications to the International Building Code (developed by the International Conference of Building Officials) required by California law and statute and has been adopted by most jurisdictions in California, including the City of South San Francisco, to oversee construction. The CBC defines four Seismic Zones in California, which are ranked according to their seismic hazard potential. Zone 1 has the least seismic potential and Zone 4 has the highest seismic potential. The City of South San Francisco is located in Seismic Zone 4 and thus development is required to comply with all design standards applicable to Seismic Zone 4. The earthquake protection law (California Health and Safety Code section 19100 et seq.) requires that structures be designed to resist stresses produced by lateral forces caused by wind and earthquakes. Specific minimum standards for seismic safety and structural design to meet earthquake protection requirements are set forth in Chapter 16 of the CBC. 1 http://www.conservation.ca.gov/cgs/shzp/Pages/Index.aspx, January 16, 2008. CHAPTER 9: GEOLOGY AND SOILS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 9-3 GEOLOGIC SETTING AND SEISMICITY REGIONAL GEOLOGY The San Francisco Bay Area lies within the Coast Range geomorphic province, a series of discontinuous northwest trending mountain ranges, ridges, and intervening valleys characterized by complex folding and faulting. The general area of Oyster Point is located on the reclaimed baylands along the westerly shores of San Francisco Bay. The bay is underlain by a depressed rock block, which is Cenozoic in age, and is wedged between two uplifted blocks featuring the East Bay Hills on the east and the Coastal Range of the San Francisco Peninsula on the west. This series of blocks is associated with the complex zone of the San Andreas fault system. The San Andreas fault is located in the Coastal Ranges along the western edge of the depressed block, and the Hayward fault (located at the base of the East Bay Hills) forms the east delineation of the depressed block. During the geologic period known as the Pleistocene Epoch, when the sea level was lowered approximately 300 feet in the Bay Area due to glacial activity, ravines and canyons were created by erosion in the elevated rock blocks. Alluvial debris was washed onto the depressed bedrock areas forming the alluvial cones, alluvial slopes, and a central plane. This central plane was an extension of Santa Clara Valley with an outlet through the Golden Gate gap to an ocean shoreline, which was miles from the present shore. As the melting of the continental ice sheets raised ocean levels, the valley, which is now San Francisco Bay, was progressively flooded by salt water. During this process, sandy alluvial deltas were built up upon the valley topography in shallow water, while in deeper water the fine-grained soils were deposited as mud. Eventually, the bay water level rose to sufficient height to submerge the alluvial cones at the margin of the valley, together with the intervening low ground and ravine outlets. Bay Mud deposits accumulated to a uniform level, burying the submerged ravines, cones, and deltas to vary depths depending upon the elevation of the original topography. The bay deposits can be summarized as follows: x Bay mud; unconsolidated and soft, consisting of silty, slightly sandy clays and sandy silts often with organic inclusions. x Alluvial sands and clays underlying the bay mud. x Lower bay clay; consolidated and of similar composition to the Bay Mud. x Sandy soils; medium to fine-grained, compact and angular, underlying the lower bay clay and directly overlying bedrock. x Bedrock; locally weathered and decomposed, consisting of sandstone, shale, and in places, serpentine and other intrusive rock. Available data indicate that the depth of the rock in the vicinity of Oyster Point ranges from near the ground surface at the western edge of the site to estimated depths of 200 feet or more at the east end of the landfill. LOCAL GEOLOGY Oyster Point is located within the historic margins of the San Francisco Bay, which is directly east of the site. According to available geological information (Bonilla, 1971)2, Oyster Point is underlain by 2 Bonilla, M.G., 1971, “Preliminary geologic map of the San Francisco South 7.5-minute quadrangle and part of the Hunters Point 7.5-minute quadrangle, California,” U.S. Geological Survey Miscellaneous Field Studies Map MF-311; scale 1:24,000. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 9-4 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT artificial fill, Bay mud, and sandstone units of the Franciscan formation. Deep channels that have been filled with Bay Mud of varying thicknesses are known to traverse shorelines in the site vicinity and have been described by others as present at the west end of the site (Treadwell & Rollo 2009a). These ancient buried channels are commonly called paleochannels. Available information pertaining to historical shorelines and known fill areas (Nichols & Wright, 1971)3 indicates that historically the Oyster Point Marina area was developed by filling a low tideland area. The fill appears to have been placed circa 1958 at the west end of Oyster Point, and after 1958 at the east end. According to a 2000 report for the Post Closure Management of the Oyster Point Landfill prepared by Gabewell with PES Environmental, the lithologic units present within and beneath the closed Oyster Point Landfill consist of a surficial clay/imported fill cap present at thicknesses from 1 to 14 feet, waste beneath the cap present up to 45 feet thick, Bay Mud present beneath the waste up to 90 feet thick, alluvial units beneath the Bay Mud of indeterminate thickness, and Franciscan bedrock that crops out a the western end of the landfill and dips steeply eastward beneath the Bay Mud and alluvium to estimated depths of about 200 feet or more. According to recent subsurface investigations by Treadwell & Rollo (2009) the thickness of the waste layer ranges from a few feet at the landfill perimeter to 35 to 40 feet over most of the site, and up to about 70 feet in some areas. FAULTING AND SEISMICITY Geologic and geomorphic structures within the San Francisco Bay Area are dominated by the San Andreas fault (SAF), a right-lateral strike-slip fault that extends from the Gulf of California in Mexico, to Cape Mendocino, on the Coast of Humboldt County in northern California. It forms a portion of the boundary between two independent tectonic plates on the surface of the earth. To the west of the SAF is the Pacific plate, which moves north relative to the North American plate, located east of the fault. In the San Francisco Bay Area, movement across this plate boundary is concentrated on the SAF; however, it is also distributed, to a lesser extent across a number of other faults that include the Hayward, Calaveras, and Concord among others. Together, these faults are referred to as the SAF system. Movement along the SAF system has been ongoing for about the last 25 million years. The northwest trend of the faults within this fault system is largely responsible for the strong northwest structural orientation of geologic and geomorphic features in the San Francisco Bay Area. The site is situated within the San Francisco Bay Area, which is characterized by numerous active faults and moderate to high seismic activity. Based on the information provided in Hart and Bryant (1997)4 the site is not located within a State-designated, Earthquake Fault Rupture Hazard Zone where site-specific studies addressing the potential for surface fault rupture are required and no known active faults traverse the site. Table 9.1 below shows the name, distance, direction, and magnitude of the closest faults to Oyster Point. 3 Nichols, D.R., and Wright, N.A., 1971, "Preliminary map of historical margins of marshland, San Francisco Bay, California,” U.S. Geological Survey Open-File Report, Basic Data Contribution 9, scale 1:125,000. 4 Hart, E.

A major seismic event on these or other nearby faults may cause substantial ground shaking at the site. GEOTECHNICAL DESIGN CONSIDERATIONS Geotechnical properties of the fill and native soils at the site that will affect the performance of future site improvements are discussed below. GENERALIZED SUBSURFACE CONDITIONS The majority of the site is underlain by landfilled solid wastes. The thickness of the landfill varies from about 4 to 70 feet and generally increases toward the center of the site. The landfill waste material consists of a variety of materials including wood, paper, plastic, cardboard, tin, rags, bricks, glass, and various organic debris mixed with varying amounts of soil. The bottom of the landfill is generally above elevation +10 feet (MSL) in the western portion of the site, and as deep as El -20 feet in the eastern portion. A soil cap varying in thickness from about 1 to 14 feet overlies the landfill areas. The soil cap consists primarily of stiff to very stiff silty and sandy clays of low to moderate plasticity, and medium dense clayey sands, with occasional gravelly clay and silty sand layers. Throughout most of the site the waste materials are underlain by very soft to soft clays and silty clays (Bay Mud) with organics and shells. The exception to this is at the western margin of the site where the waste fill is underlain by bedrock consisting of weathered claystone, sandstone, and siltstone. The Bay Mud is underlain by bedrock in the western portion of the site and by very stiff to hard clays and dense sands under the remainder of the landfill. Most of the site is underlain by 50 to 90 feet of Bay Mud. 5 International Conference of Building Officials, 1998. “Maps of Known Active Fault Near-Source Zones in California and Adjacent Portion of Nevada – To be used with the 1997 Uniform Building Code,” California Division of Mines and Geology, February. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 9-6 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Groundwater elevations range from about 5 feet to 20 feet above mean lower low water (MLLW). The higher groundwater elevations are found toward the western margin of the site where the topography is higher. The majority of the project site has a groundwater elevation from about 5 to 8 feet above MLLW. The above is a general description of the soil, rock, waste and groundwater conditions documented in the boring logs encountered in our research. Soil, rock and groundwater conditions can deviate from those encountered at the boring locations. In addition, the subsurface conditions may have changed as a result of settlement, decomposition of waste and/or erosion, and therefore the description herein may not reflect the current subsurface conditions at the site. SETTLEMENT A major geotechnical issue for design, construction and maintenance of structures at the site is settlement of the waste material and Bay Mud soils that underlie most of the waste. There are three major settlement mechanisms that are on-going at the site: consolidation settlement of the waste material and the underlying Bay Mud soils, compaction of the waste and biological decomposition shrinkage of the waste. Both consolidation and compaction of waste are load-induced settlements. Consolidation settlement results from the expulsion of water from void spaces within soil or waste in response to new loads. The Bay Mud soils that underlie the site have been undergoing consolidation settlement in response to the waste and soil fill weight since filling began in the 1950s. Laboratory test data from consolidation tests indicate that consolidation settlement of Bay Mud is on-going throughout the site. Imposition of new loads as part of new site development will lead to additional consolidation settlement of Bay Mud and waste materials below the groundwater level. Consolidation settlements are likely accruing due to the expulsion of both water and air from the waste mass. The magnitude of consolidation settlement in the waste and in the Bay Mud is difficult to estimate. However, since no new significant fill has been placed in over 40 years, it is speculated that much of the consolidation settlement of both the waste and of the underlying Bay Mud has already occurred under current loads. Compaction settlement results from crushing of the material under a new load. The magnitude of compaction settlement under new loads from new site development is of some concern, especially in the proposed building areas where grade may be raised. However, the magnitude of settlement due to waste compaction is small compared to the magnitude of settlement due to biological decomposition shrinkage, as described below. We anticipate the major portion of the settlement to be the result of decomposition of the waste. Unlike consolidation and compaction settlements, shrinkage is somewhat independent of the load. Shrinkage is defined as the settlement resulting from the biological conversion of waste with organic solids into methane, carbon dioxide and other decomposition products. The rate and magnitude of settlements resulting from the biological shrinkage of the waste is dependent on several factors including waste thickness, composition, and age of the waste. A large portion of the settlements occur within the first two years following placement with a relatively steady rate occurring after that for an indefinite period of time. Based on our review of published performance information at landfills of similar size and composition to the project site, we expect total shrinkage settlements of between 10 to 15 percent of the initial waste fill height. The thickness of the waste fill at the subject landfill varies between 1.5 and 70 feet at the deepest portion. Considering the age of the landfill and the elapsed time since closure of the landfill, the anticipated settlements are expected to fall between 3 to 6 feet over the next 15 years, for the thickest portion of the landfill at the east side of the site. Since the settlement of the landfill is time dependent and it is uncertain when the decomposition of the waste ceases to occur, it is prudent to assume that the decomposition process occurs indefinitely. CHAPTER 9: GEOLOGY AND SOILS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 9-7 Differential settlements within the waste portion of the site are difficult to predict due to the significant variety of waste material and its substantial thickness. At other landfill sites with waste thickness of approximately 25 to 30 feet, differential settlements of up to about 25 percent of the total settlement have been measured over a horizontal distance of 100 feet for a period of 12 years. Due to the uncertainties associated with settlement at the site and the substantial thickness of the waste, differential settlements could easily exceed 50 percent of the total settlement over a distance of 100 feet in the next 15 years. Consideration must also be given to differential settlement between the waste and non-waste portions (including pile supported structures) of the site. Since the non-waste areas are not expected to undergo significant settlement, the differential settlement will be equal to approximately the total settlement of the waste at the interface location. Placement of additional fill at the site will result in additional settlement due to consolidation settlement of the Bay Mud soils and the submerged waste and further compaction of waste above groundwater. The magnitude of the new settlement will depend on the thickness of the fill, the lateral extent and the current thickness of the soil cap. For estimating purposes, settlements on the order of 3 to 5 inches for every foot of new fill should be anticipated. GROUND IMPROVEMENT Several techniques are sometimes used at landfill sites in an effort to improve ground conditions and reduce settlements. Ground improvement techniques may include dynamic deep compaction or preloading with temporary soil fills. Although these techniques can reduce settlements in waste materials, they do not eliminate them as they do not prevent decomposition. Common ground improvement techniques would not likely improve the Bay Mud properties significantly across much of the site. Accordingly, we do not feel ground improvement methods are particularly feasible at Oyster Point. Seismic Hazards The site is in a region of high seismic activity and is expected to be subjected to major shaking during the design life of the project. Seismic hazards commonly investigated for projects in the site vicinity include strong-ground shaking, soil liquefaction, lateral spreading and seismic densification. Strong Ground Shaking The San Francisco Bay Area is a seismically active region. The OPSP site and region will likely be subjected to strong to violent seismically induced ground shaking within the design life of the development. The site is located in an area of active regional seismicity near active seismic sources. According to a recent study completed by the Working Group on California Earthquake Probabilities (WGCEP)6, which assesses the probability of earthquakes in the San Francisco Bay Area, there is a 62 percent probability that an earthquake of Magnitude 6.7 or greater will strike within the life of the OPSP improvements. Liquefaction Soil liquefaction is a condition in which saturated, granular soils undergo a substantial loss of strength and deformation due to pore pressure increase resulting from cyclic stress application induced by 6 Working Group On California Earthquake Probabilities (WGCEP), 2003, Earthquake Probabilities in the San Francisco Bay Region: 2002–2031, U.S. Geological Survey Open-File Report 03-214. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 9-8 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT earthquakes. In the process, the soil acquires mobility sufficient to permit both horizontal and vertical movements if the soil mass is not confined. Soils most susceptible to liquefaction are saturated, loose, clean, uniformly-graded, and fine-grained sand deposits. If liquefaction occurs, foundations resting on or within the liquefiable layer may undergo settlements. This will result in reduction of foundation stiffness and capacity. Based on the subsurface data obtained from the previous drilled borings at Oyster Point (noted above among the references reviewed), the existing landfill materials, residual soils, Bay Mud, and Franciscan Complex bedrock have a low potential for liquefaction. Therefore, damage due to liquefaction at Oyster Point is considered low. It should be noted that the landfill is contained by soil dikes along the water-side site perimeter. These perimeter dikes are reported to have been constructed of Bay Mud, which has low potential for liquefaction. Prior to new site development, geotechnical studies shall be undertaken to confirm the material types used in the construction of the perimeter dikes to verify the assumed low potential for liquefaction. Lateral Spreading Lateral spreading is a consequence of liquefaction, which results in lateral movement toward a slope. Because liquefaction potential is considered to be low at this site, the potential for lateral spreading is also considered to be low. Again, the perimeter dikes shall be evaluated to confirm that they consist of materials with low liquefaction potential. Seismic Densification During earthquake shaking, certain soils above the groundwater table may undergo densification, which could result in additional ground-surface settlement. Typically, granular soils above the water table are subject to densification during significant strong ground shaking due to earthquakes. Landfill waste material can behave as a “granular” material. Therefore, the waste material, if subject to a significant earthquake, could result in some settlement. However, based on the age of the landfill, the amount of settlement due to seismic densification is not anticipated to be greater than the future settlements anticipated as a result of the consolidation of the landfill material and underlying Bay mud. Slope Stability A principal geotechnical issue in developing final plans for the project is stability of the existing landfill perimeter dikes. Slope stability at the site is controlled primarily by the strength of the materials used in the dike construction and of the Bay Mud on which the dikes are founded. Stability analyses shall include analyses for both static stability and seismic stability under a design magnitude earthquake event. Seismic analyses shall include pseudo-static analyses to estimate permanent slope displacements due to earthquake motions. IMPACTS AND MITIGATION MEASURES STANDARDS OF SIGNIFICANCE According to CEQA Guidelines, exposure of people or structures to major geological hazards is considered a significant adverse impact. The potential geologic, geotechnical, and seismic effects of the proposed OPSP can be considered from two points of view: (1) construction impacts; and, (2) geologic hazards to people or structures. The basic criterion applied to the analysis of construction impacts is whether construction of the OPSP will create unstable geologic conditions that would last CHAPTER 9: GEOLOGY AND SOILS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 9-9 beyond the short-term construction period. The analysis of geological hazards is based on the degree to which the site geology could produce hazards to people or structures from earthquakes, ground shaking, ground movement, fault rupture, or other geologic hazards, features or events. According to CEQA Guidelines, the project would have a significant environmental impact if it were to result in: 1.The exposure of people or structures to potential substantial adverse effects, including the risk of loss, injury or death involving rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault; 2.The exposure of people or structures to potential substantial adverse effects, including the risk of loss, injury or death involving strong seismic ground shaking; 3.The exposure of people or structures to potential substantial adverse effects, including the risk of loss, injury or death involving seismic-related ground failure, including liquefaction and seismic- induced landslides; 4.The exposure of people or structures to potential substantial adverse effects, including the risk of loss, injury or death involving landslides; 5.Development located on a geologic unit or soil that is unstable (or that would become unstable as a result of the OPSP) and which could potentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction or collapse; 6.The exposure of people or structures to potential substantial adverse effects, including the risk of loss, injury or death involving volcanic hazards; 7.Development located on expansive soil, creating substantial risks to life and property; 8.The loss of topsoil or development in an area of erodible soils. 9.Development in areas where soils are incapable of adequately supporting the use of septic tanks or alternative wastewater disposal systems where sewers are not available for the disposal of wastewater; 10.The alteration or destruction of a unique geological feature. SURFACE FAULT RUPTURE Impact Geo-1: Surface Fault Rupture. According to the latest available maps, the OPSP site is not contained within an Alquist-Priolo Earthquake Fault Zone boundary. Published geologic maps of the area show the San Andreas fault (the closest known fault to the site) as lying about 7.3 kilometers (4.5 miles) to the west. The potential impact of surface fault rupture is considered less-than-significant. EXPOSURE TO STRONG SEISMIC GROUND SHAKING Impact Geo-2: Seismic Ground Shaking. There is a high probability that the proposed development will be subjected to strong to violent ground shaking from an earthquake during its design life. Strong to violent seismic ground shaking is considered a potentially significant impact. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 9-10 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Mitigation Measures Geo-2a: Compliance with California Building Code. OPSP development shall meet requirements of the California Building Code, including the California Building Standards, published by the International Conference of Building Officials, and as modified by the amendments, additions and deletions as adopted by the City of South San Francisco, California. Incorporation of seismic construction standards will reduce the potential for catastrophic effects of ground shaking, such as complete structural failure, but will not completely eliminate the hazard of seismically induced ground shaking. Geo-2b: Compliance with a design-level Geotechnical Investigation report prepared by a Registered Geotechnical Engineer and with Structural Design Plans as prepared by a Licensed Professional Engineer. Proper foundation engineering and construction shall be performed in accordance with the recommendations of a Registered Geotechnical Engineer and a Licensed Professional Engineer. The structural engineering design, with supporting Geotechnical Investigation, shall incorporate seismic parameters compliant with the California Building Code. Geo-2c: Obtain a building permit. The OPSP applicant shall obtain a building permit through the City of South San Francisco Building Division. Plan Review of planned buildings and structures shall be completed by the Building Division for adherence to the seismic design criteria for planned commercial and industrial sites in the East of 101 area of the City of South San Francisco. According to the East of 101 area plan, Geotechnical Safety Element, buildings shall not be subject to catastrophic collapse under foreseeable seismic events, and will allow egress of occupants in the event of damage following a strong earthquake. Conformity with mitigation measures Geo-2a, -2b and -2c would reduce the impact of strong seismic ground shaking to a level of less-than-significant through compliance with applicable regulations and a design-level geotechnical investigation. This applies to the entire OPSP, including the Phase I Project. SEISMICALLY INDUCED GROUND FAILURE, INCLUDING LIQUEFACTION AND GROUND SURFACE SETTLEMENT Impact Geo-3. Liquefaction, Densification, and Ground Surface Settlement. The Association of Bay Area Governments identifies the OPSP area as an area of high hazard for liquefaction. However, based on the subsurface data obtained from the previous drilled borings at Oyster Point (noted above among the references reviewed), the existing landfill materials, residual soils, Bay Mud, and Franciscan Complex bedrock have a low potential for liquefaction. Therefore, damage due to liquefaction at Oyster Point is considered low. It should be noted that the landfill is contained by soil dikes along the water-side site perimeter. These perimeter dikes are reported to have been constructed of Bay Mud, which has low potential for liquefaction. Prior to new site development, geotechnical studies shall be undertaken to confirm the material types used in the construction of the perimeter dikes to verify the assumed low potential for liquefaction. Liquefaction or densification of soils composing or underlying the perimeter dikes could result in settlement and differential settlement of site improvements including buildings, pavements, and utilities and pose a threat to human health. The potential for liquefaction of perimeter dike soils is considered a potentially significant impact. CHAPTER 9: GEOLOGY AND SOILS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 9-11 Mitigation Measures Geo-3a: Compliance with recommendations of a Geotechnical Investigation and in conformance with Structural Design Plans. A design-level Geotechnical Investigation shall be prepared for the site under the direction of a California Registered Geotechnical Engineer and shall include analysis for liquefaction potential of the site soils, particularly in the perimeter dikes. Proper foundation engineering and construction shall be performed in accordance with the recommendations of the Geotechnical Investigation. The Geotechnical Investigation shall be reviewed and approved by the City’s Geotechnical Consultant and by the City Engineer. A Registered Structural Engineer shall prepare project structural design plans. Structures shall be designed to reduce the effects of anticipated seismic settlements. The Geotechnical Engineer shall review the Structural Design Plans and provide approval for the Geotechnical elements of the plans. The design plans shall identify specific mitigation measures to reduce liquefaction potential, if the potential for liquefaction is found to exist, or other ground failure modes such as lateral spreading, seismic densification or stability of the perimeter dike slopes. Mitigation measures may include ground improvement by methods such as stone columns or jet grouting. Geo-3b: Obtain a building permit. The OPSP applicant shall obtain a building permit through the City of South San Francisco Building Division. Plan Review of planned buildings and structures shall be completed by the Building Division for adherence to the seismic design criteria for planned commercial and industrial sites in the East of 101 area of the City of South San Francisco. According to the East of 101 area plan, Geotechnical Safety Element, buildings should not be subject to catastrophic collapse under foreseeable seismic events, and will allow egress of occupants in the event of damage following a strong earthquake. Conformity with mitigation measures Geo-3a and 3b would reduce the impact of liquefaction or densification of soils composing or underlying the perimeter dikes to a level of less-than-significant. This applies to the entire OPSP, including the Phase I Project. Impact Geo-4. Perimeter Dike Stability. Based on a review of available subsurface information, the dikes that surround the site are assumed to be constructed primarily of cohesive soils derived from Bay Mud. Slope stability of the perimeter dikes is critical to the integrity of the site. Slope stability of the dikes is controlled primarily by the strength of the materials used in dike construction and of the soils on which the dikes are founded. Prior to new site development, geotechnical studies shall be undertaken to confirm the material types used in the construction of the perimeter dikes to verify that the slopes meet minimum criteria for stability under both static and seismic conditions. Failure of the perimeter dike slopes could result in settlement and differential settlement of site improvements including buildings, pavements, and utilities and pose a threat to human health. In the absence of evidence that demonstrates adequate stability of the perimeter dike slopes under both static and seismic conditions, stability of the perimeter dike slopes is considered a potentially significant impact. Mitigation Measure Geo-4: Compliance with recommendations of a Geotechnical Investigation. A design-level Geotechnical Investigation shall include an evaluation of static stability and seismic stability under a design magnitude earthquake event. Seismic analyses shall include pseudo-static analyses to estimate permanent DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 9-12 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT slope displacements due to earthquake motions. The Geotechnical Engineer shall prepare recommendations to mitigate potential slope instability, if slope stability problems are identified. Mitigation measures may include ground improvement by methods such as stone columns or jet grouting. Design-level Geotechnical Investigations shall be completed during preliminary and final design stages and will confirm material types used in the construction of the perimeter dikes to verify that the slopes meet minimum criteria for stability under both static and seismic conditions. Knowledge of the stability of the perimeter dikes will guide the selection of any future measures to mitigate any deficiencies identified in the perimeter dike. Implementation of these mitigation measures will reduce the impact of seismically-induced ground failure and seismic slope stability to a less-than-significant level. This applies to the entire OPSP, including the Phase I Project. VARIABLE SUBSURFACE CONDITIONS Impact Geo-5: Variable Subsurface Conditions and Selection of Foundation Types and Depths.Geotechnical considerations for the selection of alternative foundation types for the site include the following: The presence of Bay Mud, landfill waste and other area fill over most of the proposed building footprint areas; Varying thicknesses of Bay Mud, landfill waste and other fill; Sloping bedrock surface; and Presence of possible paleochannels in the north/northwest portions of the site. These variable subsurface conditions will influence the design, performance and constructability of foundation systems for the proposed buildings and are considered a potentially significant impact. Mitigation Measures Geo-5a: Deep Foundations. Because of the magnitude of expected settlement of Bay Mud soils and waste fill materials that would occur under new building loads, the OPSP applicant must consider the use of deep foundations such as driven piles. Specific recommendations for suitable deep foundation alternatives and required penetrations will be provided during the course of a design-level geotechnical investigation and will depend on factors such as the depth and hardness of the underlying clays, sands or bedrock, and the corrosivity of the waste materials and Bay Mud soils. Suitable deep foundation types may include driven precast, prestressed concrete piles or driven closed-end steel pipe piles with the interior of the pile filled with concrete after driving. Deep foundations shall extend through all waste materials and Bay Mud and be tipped in underlying stiff to hard clays, dense sands or weathered bedrock. Where waste and Bay Mud soils underlie the site, wall and column loads as well as floor slabs shall be founded on deep foundations. Settlement of properly-designed and constructed deep foundation elements is typically less than about one-half inch. The majority of settlement typically occurs during construction as the loads are applied. CHAPTER 9: GEOLOGY AND SOILS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 9-13 Where landfill waste and Bay Mud are not present (possibly at extreme western and northwestern edges of the site) and competent soil or bedrock are present near the ground surface (within about 5 feet of finished grade elevation), shallow foundations such as footings or mats may be appropriate foundation types, as determined during the course of a design-level geotechnical investigation. Where proposed structures straddle a transition zone between these conditions, a combination of shallow and deep foundations may be required. Any transition zones shall be identified during site-specific geotechnical investigations for preliminary and final designs. Geo-5b: Predrilling and/or Pile Configuration. Piles either shall be predrilled through the fill and landfill materials to protect the piles from damage due to unknown materials, to reduce pushing waste material deeper, and to reduce pile alignment problems or shall have a pointed tip configuration. If a drill is used, it should only loosen and break up in-place obstructions that may cause pile damage. During recent subsurface investigations reported by Treadwell & Rollo (2009b) obstructions including concrete rubble was encountered throughout the landfill area, particularly in the northern end of the site. Even with predrilling, precast concrete piles could be damaged during installation at a landfill site such as Oyster Point. For preliminary planning purposes, a precast concrete pile breakage rate during installation of 10 to 15 percent may be considered applicable. Piles usually have to include pointed tip configurations to avoid pushing landfill waste downward. These configurations are typically readily accommodated by pile driving contractors. Geo-5c: Indicator Pile Program. Prior to specifying the lengths of the production piles, drive indicator piles at the structure sites in order to observe the driving characteristic of the piles and the ability of the driving equipment when a driven pile is used. The driving criteria and pile length of production piles shall also be estimated from the information obtained from driving of the indicator piles. The contractor shall use the same equipment to drive both the indicator and production piles. Indicator pile lengths and locations shall be selected by the Geotechnical Engineer, in conjunction with the Structural Engineer and Contractor after the foundation plan has been finalized. The indicator pile program will serve to establish information on the following: x Estimates of production pile lengths; x Drivability of production piles; x Performance of pile driving equipment; and x Variation in driving resistance relative to depth and location of piles. Implementation of these mitigation measures will reduce the impact of variable subsurface conditions on the construction and performance of foundations to a less-than-significant level. This applies to the entire OPSP, including the Phase I Project. Impact Geo-6: Drag Load on Deep Foundations. The landfill wastes and the underlying Bay Mud are settling due to consolidation and on-going decomposition-induced settlement of the wastes. Deep foundations (piles) will extend through the waste and Bay Mud layers and into underlying materials that are relatively DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 9-14 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT incompressible. The settlement of the waste and Bay Mud around the piles will tend to move downward relative to the pile. This settlement will accumulate a drag load on the pile element, which will depend on the material layering and thickness, pile length and load on the pile. On-going settlement of Bay Mud soils and waste materials is considered a potentially significant impact. Mitigation Measure Geo-6: Account for Drag Load on Deep Foundations. The Geotechnical Engineer shall account for accumulation of drag load in the structural design of the deep foundations elements (piles). Implementation of this mitigation measure will reduce the impact of drag load on the performance of deep foundations to a less-than-significant level. This applies to the entire OPSP, including the Phase I Project. LANDFILL GAS AT BUILDING-SOIL INTERFACE Impact Geo-7: Landfill Gas Entry into Buildings. Construction of buildings over the landfill cap could allow landfill gas to accumulate beneath building floors and permeate into the building interiors. Landfill gas accumulation inside buildings and at the building-soil interface may adversely affect the health and safety of building occupants. Accumulation of landfill gas beneath and inside structures is a potentially significant impact. Mitigation Measure Geo-7: Incorporate Systems for Landfill Gas Control. Measures for the control of landfill gas shall be included in building design. Measures for the control of landfill gas typically include a collection system, floor slab shielding and interior alarms. Implementation of a landfill gas control system will reduce the impact of landfill gas at the building- soil interface to a level of less-than-significant. This applies to the entire OPSP, including the Phase I Project. SETTLEMENT OF LANDFILL MATERIALS AND BAY MUD Impact Geo-8: Landfill Waste Materials and Bay Mud. Placement of additional fill or other new loads at the site will result in additional site settlement due to consolidation settlement of the Bay Mud soils and the compaction and decomposition induced settlement of submerged waste and waste above groundwater. Due to the generally heterogeneous nature of the landfill, differential settlement of the soil cap will be on-going. This differential settlement can disrupt drainage patterns and cause damage to pavements, underground utilities and soil-supported structures. The magnitude of new settlement in response to additional fill will depend on the thickness of the fill, the lateral extent, and the current thickness of the soil cap. For estimating purposes, settlements on the order of 3 to 5 inches for every foot of new fill should be anticipated. Settlement due to the presence of unstable soil, waste and Bay Mud is a potentially significant impact. Mitigation Measures Geo-8a: Avoid Significant New Loads on Landfill Waste and Bay Mud. A design- level Geotechnical Investigation shall include exploration to more thoroughly CHAPTER 9: GEOLOGY AND SOILS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 9-15 determine the thickness and areal extent of landfill waste and Bay Mud. To avoid inducing additional settlement to the settlement that is already on-going, grading plans shall include as little additional new fill as possible, and significant new structure loads or any structures that are settlement-sensitive shall be founded on deep foundations extended below the Bay Mud, as recommended in the design- level Geotechnical Investigation report. All grading shall be planned to avoid penetrating the landfill cap and to reduce the amount of long-term settlement in response to new fills. Because the Bay Mud and waste across most of the site are still settling under the weight of existing fill and waste decomposition and will settle more under new fills, additional settlement should be expected, with the creation of localized low-lying surface areas. Existing low areas shall be corrected during site grading to allow for proper drainage. Long-term maintenance planning for the development shall also include provisions for periodic grading to correct drainage problems and improve site grades, as outlined in the Disposition and Development Agreement. The Geotechnical Engineer will recommend other site-specific recommendations based on the results of the design-level Geotechnical Investigation to mitigate on- going settlement and any additional settlement to be expected in response to new development. Geo-8b: Design Building-Soil Interface to Allow Free Movement. The Structural Engineer shall provide that structures not supported on deep foundations not be structurally tied into pile-supported buildings, except as noted below, and shall be designed to allow free vertical movement between structures. Articulated ramps on walkways and building entrances at the interface between the pile and soil-supported areas can provide a smooth walkway over moderate differential settlements with some amount of maintenance. As the magnitude of the differential settlement increases, however, these ramps may need to be rebuilt or realigned to account for the larger elevation differential. Similar ramps may also reduce differential settlements between driveways and pile-supported parking lots. Over time, voids will tend to form beneath pile-supported buildings due to on- going settlement of the landfill. Use of wall skirts around the building perimeter will help to reduce the visual impact of these voids. Implementation of these mitigation measures will reduce the impact of settlement and differential settlement of landfill materials and Bay Mud soils on the performance of constructed site improvements to a less-than-significant level. This applies to the entire OPSP, including the Phase I Project. UNDERGROUND UTILITIES Impact Geo-9: Hazardous Conditions During Excavation and Following Construction. Excavations extending into either the landfill cap or into the waste fill are expected to encounter potentially hazardous conditions including poisonous and explosive gases. This may be true in shallower excavations as well. This is a potentially significant impact during and following site construction activities. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 9-16 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Mitigation Measures Geo-9a: Monitoring and Testing. Special precautions shall be taken to monitor the safety conditions and to provide for the safety of workers in the area. Additionally, if excavations encounter water, this water shall be tested for contaminants and may have to undergo specialized handling, treatment and/or disposal if it is contaminated. A system to disperse methane during construction shall be installed in or adjacent to the trenches. Geo-9b: Locate Underground Utilities in Soil Cap. To the extent practicable, the utilities shall be constructed in the soil landfill cap to avoid direct contact of the utility lines and construction workers with the waste material. If construction of utilities in the waste material is necessary, proper design and construction precautions shall be taken to protect the system and the workers from the corrosive and hazardous conditions of the waste. Geo-9c: Seal Trenches and Underground Structures. Trenches and underground structures shall be sealed to preclude gas intrusion. Typical types of sealing procedures include providing a low permeability clay cover of 1 foot over the top of the pipe, or the utility trench be lined with a relatively impervious geomembrane. Underground manholes may be shielded from methane intrusion by placement of a membrane around the outside of the structure. To reduce gas migration off-site within the utility trenches, all trenches crossing the transition zone between the landfill and non-landfill portions of the property shall be sealed with a clay plug surrounding the pipe or other approved methods. In addition, plugs shall also be provided at the perimeters of buildings to reduce migration of gas through the utility trenches to beneath the buildings. Implementation of these mitigation measures will reduce the impact of hazardous conditions due to high landfill gas concentrations during excavation and on the constructed improvements to a less- than-significant level. This applies to the entire OPSP, including the Phase I Project. Impact Geo-10: Damage to Landfill Cap Due to Excavation. Excavations for buildings, utilities and other underground structures that extend into the landfill cap may result in damage to the landfill cap. This would be a potentially significant impact on safety during and after construction and on the continued performance of the landfill cap. Mitigation Measure Geo-10: Provide For Continuity of Landfill Cap. Following planned landfill excavation and landfill cap repair, the project Civil Engineer shall require that excavations for building foundations, utility trenches and other underground structures be configured to maintain continuity of the landfill cap. The specific configuration will depend upon the excavation depth and orientation to underlying wastes. However, a low-permeability layer of soil or a geomembrane properly tied to surrounding cap areas may be required. Provisions for landfill continuity of the landfill cap following planned landfill excavation and landfill cap repair, designed by a qualified Civil Engineer, will reduce the impact level of excavations into the landfill cap to less than significant. This applies to the entire OPSP in the vicinity of the landfill, including the Phase I Project. CHAPTER 9: GEOLOGY AND SOILS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 9-17 Impact Geo-11: Stresses at Building Connections. Underground utilities will be subject to distress at building connection locations due to differential settlement. It is anticipated that the most crucial sections of the utility lines will occur at the interface between the soil supported utility line and the pile supported buildings. At this interface differential settlements of several feet are possible. This would be a potentially significant impact on the performance of underground utilities. Mitigation Measure Geo-11: Common Trenches and Vaults. Where underground utilities are to be located in landfill areas, consideration shall be given to reducing the number of utilities trenches by locating utilities in common trenches to the extent practicable. In addition, vaulted systems shall be designed and maintained at such interfaces that provide flexible and/or expandable connections to the proposed buildings. In addition, the utility lines beneath buildings shall be suspended from hangers fastened to structural floor slabs. Implementation of these measures will reduce utility stresses at building connections to levels less than significant. However, even with special design to mitigate the expected differential settlement, extra maintenance and repair will be necessary on the utility lines located in the landfill area. This applies to the entire OPSP, including the Phase I Project. Impact Geo-12: Stresses in Utility Line Materials. Differential settlement will cause distress to the materials used in underground utilities construction. On a landfill site the effects of differential settlement are typically more severe than at a conventional site due to the generally higher levels of settlement that occur. Differential settlement is a potentially significant impact on the performance of underground utilities. Mitigation Measure Geo-12: Flexible Materials and Joints. Utility lines shall be constructed of flexible pipe such as welded polyethylene to accommodate differential settlement within the waste material and landfill cap. At the border of the landfill, where differential settlements are expected to be large, the utility lines shall be designed to allow for rotation. As with buried utilities on a conventional site, proper bedding and backfilling shall be completed, as specified in a design-level geotechnical investigation report. Use of flexible materials and joints in underground utilities will reduce distress of the buried utilities to levels less than significant. However, even with special design to mitigate the expected differential settlement, extra maintenance and repair will be necessary on the utility lines located in the landfill area. This applies to the entire OPSP, including the Phase I Project. Impact Geo-13: Disruption of Flow Gradient. Differential settlement will tend to disrupt flow gradients in gravity-flow sewers and storm drains. This is a potentially significant impact on the performance of these utilities. Mitigation Measure Geo-13: Increase Flow Gradient. The Civil Engineer shall consider increasing the flow gradient in sewers and storm drains so that differential settlements will not disrupt the flow. An alternative is to provide a pumping system that does not rely on gravity flow. Such measures will reduce the impact of reduced flow gradient due to differential settlement to less than significant. This applies to the entire OPSP, including the Phase I Project. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 9-18 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Detailed design of utilities, landfill gas shielding and collection systems, foundation systems and floor slabs will require careful coordination among civil, environmental, structural and geotechnical consultants. Even with careful design and construction, the need for utility maintenance will likely be greater than at a conventional site. SOIL EROSION Impact Geo-14: Soil Erosion. The OPSP would involve mass grading at a location that drains stormwater to the San Francisco Bay. Demolition of existing structures and pavements could expose underlying landfill cap soils to the elements. Excavation of soil for construction of new buildings and pavement sections would also be performed and temporary stockpiles of loose soil will be created. Soils exposed during site grading would be subject to erosion during storm events. Grading would disturb site soils potentially leading to impacts to the San Francisco Bay. This would be a potentially significant impact during and following site construction activities. Mitigation Measure Geo-14: Storm Water Pollution Prevention Plan. In accordance with the Clean Water Act and the State Water Resources Control Board (SWRCB), the Applicant shall file a Storm Water Pollution Prevention Plan (SWPPP) prior to the start of construction. The SWPPP shall include specific best management practices to reduce soil erosion. This is required to obtain coverage under the General Permit for Discharges of Storm Water Associated with Construction Activity (Construction General Permit, 99-08-DWQ). Implementation of a storm water pollution prevention plan (mitigation measure Geo-14) will reduce the impact of soil erosion to a level of less-than-significant. This applies to the entire OPSP, including the Phase I Project. EXPANSIVE SOILS Impact Geo-15: Expansive Soils. Available existing geotechnical information for the OPSP site does not identify the presence of highly-plastic, near-surface expansive soils. Therefore, at this time the impact of expansive soils with respect to shallow foundations is considered to be less-than-significant. This applies to the entire OPSP, including the Phase I Project. LANDSLIDES The OPSP site is a nearly level area with no nearby hills that could fail by landsliding. There is no impact related to landslides. This applies to the entire OPSP, including the Phase I Project. VOLCANIC HAZARDS The OPSP site is not located in an active volcano or volcanic hazard area. There is no impact related to volcanic hazards. This applies to the entire OPSP, including the Phase I Project. CHAPTER 9: GEOLOGY AND SOILS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 9-19 SEPTIC SYSTEMS A sewer system is present in the area and septic systems are not required at the site. The OPSP would have no impact related to septic systems. This applies to the entire OPSP, including the Phase I Project. UNIQUE GEOLOGICAL FEATURES No unique geologic features will be impacted by the proposed OPSP. The OPSP would have no impact related to unique geological features. This applies to the entire OPSP, including the Phase I Project. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 9-20 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT This page intentionally left blank. OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 10-1 10 GREENHOUSE GAS EMISSIONS SETTING There is a general scientific consensus that global climate change is occurring, caused in whole or in part, by increased emissions of greenhouse gases (GHGs) that keep the Earth’s surface warm by trapping heat in the Earth’s atmosphere1, in much the same way as glass traps heat in a greenhouse. While many studies show evidence of warming over the last century and predict future global warming, the precise causes of such warming and its potential effects are far less certain.2 In its “natural” condition, the greenhouse effect is responsible for maintaining a habitable climate on Earth, but human activity has caused increased concentrations of these gases in the atmosphere, thereby contributing to an increase in global temperatures. The U.S. EPA has recently concluded that scientists know with virtual certainty that: “Human activities are changing the composition of Earth’s atmosphere. Increasing levels of greenhouse gases like CO2 in the atmosphere since pre-industrial times are well documented and understood. x The atmospheric buildup of CO2 and other greenhouse gases is largely the result of human activities such as the burning of fossil fuels. x A warming trend of approximately 0.7 to 1.5°F occurred during the 20th century. Warming occurred in both the northern and southern hemispheres, and over the oceans. x The major greenhouse gases emitted by human activities remain in the atmosphere for periods ranging from decades to centuries. It is, therefore, virtually certain that atmospheric concentrations of greenhouse gases will continue to rise over the next few decades. Increasing greenhouse gas concentrations tend to warm the planet.”3 At the same time, there is much uncertainty concerning the magnitude and rate of the warming. Specifically, the U.S. EPA notes that “important scientific questions remain about how much warming will occur; how fast it will occur; and how the warming will affect the rest of the climate system, including precipitation patterns and storms. Answering these questions will require advances in scientific knowledge in a number of areas: 1 U.S. Environmental Protection Agency (U.S. EPA), Global Warming – Climate: Uncertainties (web page), January 2000, http://yosemite.epa.gov/oar/globalwarming.nsf/content/ClimateUncertainties.html#likely, accessed July 24, 2007. 2 “Global climate change” is a broad term used to describe any worldwide, long-term change in the earth’s climate. “Global warming” is more specific and refers to a general increase in temperatures across the earth, although it can cause other climatic changes, such as a shift in the frequency and intensity of weather events and even cooler temperatures in certain areas, even though the world, on average, is warmer. 3 U.S. EPA, 2000, op. cit. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 10-2 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT o Improving understanding of natural climatic variations, changes in the sun’s energy, land-use changes, the warming or cooling effects of pollutant aerosols, and the impacts of changing humidity and cloud cover. o Determining the relative contribution to climate change of human activities and natural causes. o Projecting future greenhouse emissions and how the climate system will respond within a narrow range. o Improving understanding of the potential for rapid or abrupt climate change.”4 GREENHOUSE GASES Carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), ozone (O3), and water vapor (H2O) are the principal GHGs, and when concentrations of these gases exceed the natural concentrations in the atmosphere, the greenhouse effect may be enhanced. Without these GHGs, Earth’s temperature would be too cold for life to exist. CO2, CH4, and N2O occur naturally, as well as through human activity. Of these gases, CO2 and CH4 are emitted in the greatest quantities from human activities. Emissions of CO2 are largely byproducts of fossil fuel combustion, whereas CH4 results from off gassing associated with agricultural practices and landfills. Man-made GHGs–with much greater heat-absorption potential than CO2–include fluorinated gases, such as hydrofluorocarbons (HFCs), perfluorocarbons (PFC), and sulfur hexafluoride (SF6), which are byproducts of certain industrial processes.5 POTENTIAL EFFECTS OF HUMAN ACTIVITY ON GHG EMISSIONS As mentioned above, the primary GHG generated by human activity is CO2. Fossil fuel combustion, especially for the generation of electricity and powering of motor vehicles, has led to substantial increases in CO2 emissions (and thus substantial increases in atmospheric concentrations). In 1994, atmospheric CO2 concentrations were found to have increased by nearly 30 percent above pre- industrial (c.1860) concentrations. The effect each GHG has on climate change is measured as a combination of the volume of its emissions, and its global warming potential (GWP),6 and is expressed as a function of how much warming would be caused by the same mass of CO2. Thus, GHG emissions are typically measured in terms of pounds or tons of CO2 equivalents (CO2e). (1) Global Emissions. Worldwide emissions of GHGs in 2004 were 30 billion tons of CO2e per year7 (including both ongoing emissions from industrial and agricultural sources, but excluding emissions from land-use changes). (2) U.S. Emissions. In 2004, the United States emitted about 8 billion tons of CO2e or about 25 tons/year/person.

CHAPTER 10: GREENHOUSE GAS EMISSIONS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 10-3 transportation - transportation accounts for the highest fraction of GHG emissions (approximately 35 to 40 percent); these emissions are entirely generated from direct fossil fuel combustion.8 (3) State of California Emissions. In 2004, California emitted approximately 550 million tons of CO2e, or about 6 percent of the U.S. emissions. This large number is due primarily to the sheer size of California compared to other states. By contrast, California has one of the fourth lowest per capita GHG emission rates in the country, due to the success of its energy-efficiency and renewable energy programs and commitments that have lowered the State’s GHG emissions rate of growth by more than half of what it would have been otherwise.9 Another factor that has reduced California’s fuel use and GHG emissions is its mild climate compared to that of many other states. The California EPA Climate Action Team stated in its March, 2006, report that the composition of gross climate change pollutant emissions in California in 2002 (expressed in terms of CO2 equivalence) were as follows: x Carbon dioxide (CO2) accounted for 83.3 percent; x Methane (CH4) accounted for 6.4 percent; x Nitrous oxide (N2O) accounted for 6.8 percent; and x Fluorinated gases (HFCs, PFC, and SF6) accounted for 3.5 percent.10 The California Energy Commission found that transportation is the source of approximately 41 percent of the State’s GHG emissions, followed by electricity generation (both in-state and out of- state) at 23 percent, and industrial sources at 20 percent. Agriculture and forestry is the source of approximately 8.3 percent, as is the source categorized as “other,” which includes residential and commercial activities.11 (4) Bay Area Emissions. In the Bay Area, fossil fuel consumption in the transportation sector (on- road motor vehicles, off-highway mobile sources, and aircraft) is the single largest source of the Bay Area’s GHG emissions, accounting for just over half of the Bay Area’s 85 million tons of GHG emissions in 2002. Industrial and commercial sources were the second largest contributors of GHG emissions with about 25 percent of total emissions. Domestic sources (e.g., home water heaters, furnaces, etc.) account for about 11 percent of the Bay Area’s GHG emissions, followed by power plants at 7 percent. Oil refining currently accounts for approximately 6 percent of the total Bay Area GHG emissions.12 BAAQMD updated the GHG emission inventory in 2008 to reflect the base year inventory for 200713. This updated inventory includes additional sources of GHG emissions such as those from electricity generation outside of the Bay Area, use of ozone depleting substances (e.g., refrigerants), additional sources from oil refining, and ship emissions extended out to 100 miles (the 2002 inventory only looked at emissions 3 miles out). The new inventory also reflects year 2007 8 U.S. EPA, 2000, op. cit. 9 California Energy Commission (CEC), Inventory of California Greenhouse Gas Emissions and Sinks: 1990 to 2004 - Final Staff Report, publication # CEC-600-2006-013-SF, Sacramento, CA, December 22, 2006; and January 23, 2007 update to that report. 10 CalEPA, 2006b, op. cit. 11 California Energy Commission (CEC), 2007, op. cit. 12 BAAQMD, 2006.

DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 10-4 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT activity. As a result, the 2007 Bay Area region-wide inventory was estimated at 102.7 MMCO2e. Much of the difference between the 2002 and the 2007 inventories is attributable to the methodology of the computations. About 46-percent of the County inventory is attributable to on-road vehicles. (5) City of South San Francisco Emissions. At present, the City of South San Francisco does not have an adopted plan or specific policies to reduce GHG emissions, although many of the City’s policies and ordinances—such as one of the region’s most aggressive Transportation Demand Management (TDM) programs—achieve the same objective. The City is completing an emissions survey that will provide a basis for formally developing such tools. Although the General Plan did not specify policies and programs designed to reduce GHG emissions, many of the Plan’s policies will contribute to this objective by promoting development that is less reliant on motor vehicles. Further, the Update carries forward South San Francisco’s current TDM Ordinance, which requires that non- residential development generating more than 100 daily trips, must incorporate measures to ensure that at least 28% of all trips are made through alternative mode use. As incentives to implement programs that will further reduce vehicle trips, the TDM provisions provide a floor area ratio (FAR) bonus in accordance with the General Plan when 30% to 45% of all trips involve alternative mode use, depending on the type of development and requested FAR. Adherence to such requirements would reduce potential impacts associated with this issue to a no impact level. As shown in Table 10.1, below, South San Francisco emitted approximately 527,000 tons of CO2 equivalents (CO2e) in 2005 from all major sources, nearly half of which were from transportation Table 10.1: GHG Emission Inventory for South San Francisco Community-Wide Emissions - 2005 (Metric Tons/Year) Potential Source Tons of Carbon Dioxide Equivalent (CO2e) Percent of Total Transportation City Roads (Non-Highway) State Highways 240,257 87,406 152,851 46% 17% 29% Commercial/Industrial Electrical Natural Gas 185,240 80,723 104,517 35% 15% 20% Residential Electrical Natural Gas 70,059 22,258 47,801 13% 4% 9% Waste 31,210 6% Total 526,766 100% Source: City of South San Francisco Zoning Ordinance Update, December 17, 2009 It is easy to dismiss the impact any single community can have on GHG emissions. In the context of the State of California, the City of South San Francisco accounts for .001 percent (perhaps slightly higher, if we account for traffic outside the city borders and waste impacts) of GHG emissions. However, it is important to understand that reduction of GHG emissions is partially a matter of the availability of options in transportation and other energy use. Achievement of the reductions required by Measure G and State law require local action. CHAPTER 10: GREENHOUSE GAS EMISSIONS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 10-5 POTENTIAL EFFECTS OF HUMAN ACTIVITY ON GLOBAL CLIMATE CHANGE Globally, climate change has the potential to impact numerous environmental resources through potential, though uncertain, impacts related to future air temperatures and precipitation patterns. Scientific modeling predicts that continued GHG at or above current rates would induce more extreme climate changes during the 21st century than were observed during the 20th century. A warming of about 0.2°C (0.36°F) per decade is projected, and there are identifiable signs that global warming is taking place, including substantial ice loss in the Arctic.14 However, the understanding of GHG emissions, particulate matter, and aerosols on global climate trends remains uncertain. In addition to uncertainties about the extent to which human activity rather than solar or volcanic activity is responsible for increasing warming, there is also evidence that some human activity has cooling, rather than warming, effects, as discussed in detail in numerous publications by the International Panel on Climate Change (IPCC), namely “Climate Change 2001, The Scientific Basis” (2001).15 Acknowledging uncertainties regarding the rate at which anthropogenic greenhouse gas emissions would continue to increase (based upon various factors under human control, such as future population growth and the locations of that growth; the amount, type, and locations of economic development; the amount, type, and locations of technological advancement; adoption of alternative energy sources; legislative and public initiatives to curb emissions; and public awareness and acceptance of methods for reducing emissions), and the impact of such emissions on climate change, the IPCC devised a set of six “emission scenarios” which utilize various assumptions about the rates of economic development, population growth, and technological advancement over the course of the next century.16 These emission scenarios are paired with various climate sensitivity models to attempt to account for the range of uncertainties that affect climate change projections. The wide range of temperature, precipitation, and similar projections yielded by these scenarios and models reveal the magnitude of uncertainty presently limiting climate scientists’ ability to project long-range climate change (as previously discussed). The projected effects of global warming on weather and climate are likely to vary regionally, but are expected to include the following direct effects, according to the IPCC.17 x Snow cover is projected to contract, with permafrost areas sustaining thawing. x Sea ice is projected to shrink in both the Arctic and Antarctic. x Hot extremes, heat waves, and heavy precipitation events are likely to increase in frequency. x Future tropical cyclones (typhoons and hurricanes) will likely become more intense. x Non-tropical storm tracks are projected to move poleward, with consequent changes in wind, precipitation, and temperature patterns. Increases in the amount of precipitation are very likely in high-latitudes, while decreases are likely in most subtropical regions. 14 International Panel on Climate Change (IPCC) Special Report on Emissions Scenarios, 2000, www.grida.no/climate/ipcc/emission/002.htm, accessed July 24, 2007. 15 The IPCC was established in 1988 by the World Meteorological Organization and the United Nations Environment Program to assess scientific, technical and socio-economic information relevant for the understanding of climate change, its potential impacts and options for adoption and mitigation. 16 IPCC, 2000, op. cit. 17 Ibid. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 10-6 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT x Warming is expected to be greatest over land and at most high northern latitudes, and least over the Southern Ocean and parts of the North Atlantic Ocean. Potential secondary effects from global warming include global rise in sea level, impacts to agriculture, changes in disease vectors, and changes in habitat and biodiversity. POTENTIAL EFFECTS OF HUMAN ACTIVITY ON STATE OF CALIFORNIA According to CARB, some of the potential impacts in California of global warming may include loss in snow pack, sea level rise, more extreme heat days per year, more high ozone days, more large forest fires, and more drought years.18 Several recent studies have attempted to explore the possible negative consequences that climate change, left unchecked, could have in California. These reports acknowledge that climate scientists’ understanding of the complex global climate system, and the interplay of the various internal and external factors that affect climate change, remains too limited to yield scientifically valid conclusions on such a localized scale. Substantial work has been done at the international and national level to evaluate climatic impacts, but far less information is available on regional and local impacts. In addition, projecting regional impacts of climate change and variability relies on large-scale scenarios of changing climate parameters, using information that is typically at too general a scale to make accurate regional assessments.19 Below is a summary of some of the potential effects reported in an array of studies that could be experienced in California as a result of global warming and climate change: x Air Quality – Higher temperatures, conducive to air pollution formation, could worsen air quality in California. Climate change may increase the concentration of ground-level ozone, but the magnitude of the effect, and therefore its indirect effects, are uncertain. For other pollutants, the effects of climate change and/or weather are less well studied, and even less well understood.20 If higher temperatures are accompanied by drier conditions, the potential for large wildfires could increase, which, in turn, would further worsen air quality. However, if higher temperatures are accompanied by wetter, rather than drier conditions, the rains would tend to temporarily clear the air of particulate pollution and reduce the incidence of large wildfires, thus ameliorating the pollution associated with wildfires. Additionally, severe heat accompanied by drier conditions and poor air quality could increase the number of heat related deaths, illnesses, and asthma attacks throughout the State.21 x Water Supply – Uncertainty remains with respect to the overall impact of global climate change on future water supplies in California. For example, models that predict drier conditions (i.e., parallel climate model [PCM]) suggest decreased reservoir inflows and storage and decreased river flows, relative to current conditions. By comparison, models that predict wetter conditions (i.e., HadCM2) project increased reservoir inflows and storage, and increased river flows.22 18 California Air Resources Board (CARB), 2006c.

Although the report projects that “climate change will likely have a significant effect on California’s future water resources and future water demand,” it also reports that “much uncertainty about future water demand remains, especially for those aspects of future demand that will be directly affected by climate change and warming. While climate change is expected to continue through at least the end of this century, the magnitude and, in some cases, the nature of future changes is uncertain. This uncertainty serves to complicate the analysis of future water demand, especially where the relationship between climate change and its potential effect on water demand is not well understood.”23 DWR adds “it is unlikely that this level of uncertainty will diminish significantly in the foreseeable future.”24 Still, changes in water supply are expected to occur, and many regional studies have shown that large changes in the reliability of water yields from reservoirs could result from only small changes in inflows.25 Water purveyors, such as the East Bay Municipal Utilities District (EBMUD), are required by state law to prepare Urban Water Management Plans (UWMPs) (discussed below, under Regulatory Context forGreenhouse Gas Emissions and Climate Change) that consider climatic variations and corresponding impacts on long-term water supplies.26 DWR has published a 2005 SWP Delivery Reliability Report, which presents information from computer simulations of the SWP operations based on historical data over a 73-year period (1922–1994). The DWR notes that the results of those model studies “represent the best available assessment of the delivery capability of the SWP.” In addition, the DWR is continuing to update its studies and analysis of water supplies. EBMUD would incorporate this information from DWR in its update of its current UWMP 2005 (required every five years per the California Water Code), and information from the UWMP can be incorporated into Water Supply Assessments (WSAs) and Water Verifications prepared for certain development projects in accordance with Cal. Water Code Section 10910, et seq. and Cal. Government Code Section 66473.7, et seq. x Hydrology – As discussed above, climate change could potentially affect the amount of snowfall, rainfall and snow pack; the intensity and frequency of storms; flood hydrographs (flash floods, rain or snow events, coincidental high tide and high runoff events); sea level rise and coastal flooding; coastal erosion; and the potential for salt water intrusion. Sea level rise can be a product of global warming through two main processes: expansion of seawater as the oceans warm, and melting of ice over land. A rise in sea levels could result in coastal flooding and erosion and could also jeopardize California’s water supply. In particular, saltwater intrusion would threaten the quality and reliability of the state’s major fresh water supply that is pumped from the southern portion of the Sacramento/San Joaquin River Delta. Increased storm intensity and frequency could affect the ability of flood-control facilities (including levees) to handle storm events. x Agriculture – California has a $30 billion agricultural industry that produces half the country’s fruits and vegetables.

DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 10-8 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT can stimulate plant production and increase plant water-use efficiency. However, if temperatures rise and drier conditions prevail, water demand could increase; crop-yield could be threatened by a less reliable water supply; and greater ozone pollution could render plants more susceptible to pest and disease outbreaks. In addition, temperature increases could change the time of year that certain crops, such as wine grapes, bloom or ripen, and thus affect their quality.27 x Ecosystems and Wildlife – Increases in global temperatures and the potential resulting changes in weather patterns could have ecological effects on a global and local scale. In 2004, the Pew Center on Global Climate Change released a report examining the possible impacts of climate change on ecosystems and wildlife.28 The report outlines four major ways in which it is thought that climate change could affect plants and animals: (1) timing of ecological events; (2) geographic range; (3) species’ composition within communities; and (4) ecosystem processes such as carbon cycling and storage. REGULATORY CONTEXT FOR GHG EMISSIONS AND CLIMATE CHANGE International and Federal Kyoto Protocol. The United States participates in the United Nations Framework Convention on Climate Change (UNFCCC) (signed on March 21, 1994). The Kyoto Protocol is a treaty made under the UNFCCC and was the first international agreement to regulate GHG emissions. It has been estimated that if the commitments outlined in the Kyoto Protocol are met, global GHG emissions could be reduced by an estimated 5 percent from 1990 levels during the first commitment period of 2008– 2012. It should be noted that although the United States is a signatory to the Kyoto Protocol, Congress has not ratified the Protocol and the United States is not bound by the Protocol’s commitments. Climate Change Technology Program. The United States has opted for a voluntary and incentive- based approach toward emissions reductions in lieu of the Kyoto Protocol’s mandatory framework. The Climate Change Technology Program (CCTP) is a multi-agency research and development coordination effort (which is led by the Secretaries of Energy and Commerce) that is charged with carrying out the President’s National Climate Change Technology Initiative.29 U.S. Environmental Protection Agency (U.S. EPA). To date, the U.S. EPA has not regulated GHGs under the Clean Air Act (discussed above) based on its assertion in Massachusetts et al. v. EPA et al30 that the “Clean Air Act does not authorize it to issue mandatory regulations to address global climate change and that it would be unwise to regulate GHG emissions because a causal link between GHGs and the increase in global surface air temperatures has not been unequivocally established.” However, in the same case (Massachusetts v. EPA), the U.S. Supreme Court held that the U.S. EPA can, and should, consider regulating motor-vehicle GHG emissions. 27 California Climate Change Center (CCCC), 2006, op. cit. 28 Parmesan, C. and H.

On July 1, 2002, the California Assembly passed Assembly Bill (AB) 1493 (signed into law on July 22, 2002), requiring the CARB to “adopt regulations that achieve the maximum feasible and cost-effective reduction of GHG emissions from motor vehicles.” The regulations were to be adopted by January 1, 2005, and apply to 2009 and later model-year vehicles. In September 2004, CARB responded by adopting “CO2-equivalent fleet average emission” standards. The standards will be phased in from 2009 to 2016, reducing emissions by 22 percent in the “near term” (2009–2012) and 30 percent in the “mid term” (2013– 2016), as compared to 2002 fleets. Executive Order (EO) S-3-05. On June 1, 2005, Governor Arnold Schwarzenegger signed Executive Order (EO) S-3-05, establishing statewide GHG emissions reduction targets. This EO provides that by 2010, emissions shall be reduced to 2000 levels; by 2020, emissions shall be reduced to 1990 levels; and by 2050, emissions shall be reduced to 80 percent of 1990 levels. The Secretary of the California Environmental Protection Agency (CalEPA) is charged with coordinating oversight of efforts to meet these targets and formed the Climate Action Team (CAT) to carry out the EO. Several of the programs developed by the CAT to meet the emission targets are relevant to residential construction and are outlined in a March 2006 report.31 These include prohibition of idling of certain classes of construction vehicles; provision of recycling facilities within residential buildings and communities; compliance with the Energy Commission’s building and appliance energy efficiency standards; compliance with California’s Green Buildings and Solar initiatives; and implementation of water-saving technologies and features. California Assembly Bill 32 (AB 32). On August 31, 2006, the California Assembly passed Bill 32 (AB 32) (signed into law on September 27, 2006), the California Global Warming Solutions Act of 2006. AB 32 commits California to reduce GHG emissions to 1990 levels and establishes a multi-year regulatory process under the jurisdiction of the CARB to establish regulations to achieve these goals. CARB must adopt such regulations by January 1, 2008. The regulations shall require monitoring and annual reporting of GHG emissions from selected sectors or categories of emitters of GHGs. By January 1, 2008, CARB was also required to adopt a statewide GHG emissions limit equivalent to the statewide GHG emissions levels in 1990, which must be achieved by 2020. By January 1, 2011, CARB is required to adopt rules and regulations, which shall become operative January 1, 2012) to achieve the maximum technologically feasible and cost-effective GHG emission reductions. On April 20, 2007, CARB published Proposed Early Actions to Mitigate Climate Change in California.32 This publication indicated that the issue of GHG emissions in CEQA and GeneralPlans was being deferred for later action, so the publication did not discuss any early actionmeasures generally related to CEQA or to land use decisions. As noted in that report: “AB 32requires that all GHG reduction measures adopted and implemented by the Air Resources Boardbe technologically feasible and cost effective.”33 The law permits the use of market-basedcompliance mechanisms to achieve those reductions and also requires that GHG measures haveneither negative impacts on conventional pollutant controls nor any disproportionatesocioeconomic effects (among other criteria). 31 California Environmental Protection Agency (CalEPA), 2006a.

DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 10-10 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT On October 24, 2008, CARB released a “Preliminary Draft Staff Proposal,” “Recommended Approaches for Setting Interim Significance Thresholds for Greenhouse Gas under the California Environmental Quality Act”. AB 32 also requires CARB to monitor compliance with and enforcement of any rule, regulation, order, emission limitation, emissions reduction measure, or market-based compliance mechanism that it adopts. California Senate Bill 97 (SB 97). Governor Schwarzenegger signed SB 97 (Chapter 185, Statutes 2007) into law on August 24, 2007. The legislation provides partial guidance on how greenhouse gases should be addressed in certain CEQA documents. Pursuant to Senate Bill 97, the Natural Resources Agency reviewed and adopted the amendments to the CEQA Guidelines on December 30, 2010, prepared and forwarded by the Governor’s Office of Planning and Research (OPR), including guidelines addressing GHGs. The Amendments became effective on March 18, 2010. OPR recommends that each agency develop an approach to addressing GHG emissions that is based on best available information. The approach includes three basic steps: (1) identify and quantify emissions; (2) assess the significance of the emissions; and (3) if emissions are significant, identify mitigation measures or alternatives that will reduce the impact to a less-than-significant level. California Urban Water Management Act. The California Urban Water Management Planning Act requires various water purveyors throughout the State of California (such as EBMUD) to prepare UWMPs, which assess the purveyor’s water supplies and demands over a 20-year horizon (California Water Code, Section 10631 et seq.). As required by that statute, UWMPs are updated by the purveyors every five years. As discussed above, this is relevant to global climate change, which may affect future water supplies in California, as conditions may become drier or wetter, affecting reservoir inflows and storage and increased river flows.34 Senate Bill 375. Senate Bill 375, signed into law in October, 2008, requires CARB to establish regional targets for reduction of GHG emissions due to transportation and land use, requires metropolitan planning organizations (Association of Bay Area Governments in the Bay Area) to prepare regional sustainable land use plans to reach these targets, and directs regional transportation agencies (Metropolitan Transportation Commission in the Bay Area) to ensure that regional transportation plans are consistent with and support the regional sustainability plans. Many infill development projects consistent with these plans will be exempt from CEQA. The process of establishing targets and plans is expected to take several years, based on timelines in SB 375. However, the Association of Bay Area Governments (ABAG) has already begun preparing revised Policy-Based Projections for its 2009 land use projections, and has estimated GHG impacts as part of its initial assessment of alternative projection scenarios. Overall, the Bay Area is expected to grow by approximately 2,000,000 people by 2035. DRAFT Projections 2009 have been released for jurisdictional staff review. In order to accommodate the increased population and meet the mandates of AB 32, the draft projections have a significantly increased focus on higher intensity transit-oriented development as a key strategy. 34 Brekke, 2004, op. cit. CHAPTER 10: GREENHOUSE GAS EMISSIONS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 10-11 IMPACTS AND MITIGATION MEASURES THRESHOLDS OF SIGNIFICANCE Appendix G of the CEQA Guidelines (Environmental Checklist) contains a list of air quality effects that may be considered significant. Implementation of the OPSP, including the Phase I Project, would have a significant effect on the environment if it were to: x Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment x Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions of greenhouse gases In June 2010 the Bay Area Air Quality Management District (BAAQMD) adopted the new CEQA Air Quality Guidelines; these guidelines are for project level and program level analyses. If a project or plan is located in a community with an adopted qualified GHG Reduction Strategy, the project may be considered less than significant if it is consistent with the GHG Reduction Strategy. South San Francisco does not have an adopted GHG Reduction Strategy, so this threshold cannot be used. In the absence of a GHG Reduction Strategy, a project or plan can be compared to a quantitative threshold. BAAQMD provides two alternative quantitative thresholds, a brightline threshold of 1,100 MT of CO2e per year to assess smaller projects or an efficiency-based threshold of 4.6 MT CO2e per Service Population (SP) per year to assess larger projects. BAAQMD defines the SP as the number of residents and employees generated by the project or plan. Since the City has not yet adopted a qualified GHG Reduction Strategy and the OPSP would be too large to compare against the brightline threshold, a significant impact with respect to GHG emissions would occur if annual CO2e emissions from the Phase I Project or the OPSP exceed the efficiency threshold of 4.6 metric tons per SP. While BAAQMD provides an alternate efficiency-based threshold for General Plans or regional transportation and air quality plans, the above thresholds are the same for both a project and a specific plan. It should be noted that it is BAAQMD policy that these adopted thresholds do not apply to projects for which a Notice of Preparation was published prior to the effective date of June 2, 2010. The Notice of Preparation for this analysis was published on February 26, 2010, well before this date. However, given that there were no previous quantitative thresholds and that these are the same as the interim thresholds in place at that time of publication of the Notice of Preparation, they are conservatively used in this analysis as the best available thresholds. GREENHOUSE GAS EMISSIONS AND CLIMATE CHANGE The adoption of the OPSP, in itself, will have no impacts related to GHG. However, individual projects developed in conformance with the OPSP will generate GHG impacts from their construction and operation. Overall, the following activities associated with a typical development could contribute to the generation of GHG emissions: x Removal of Vegetation. The net removal of vegetation for construction results in a loss of the carbon sequestration in plants. However, planting of additional vegetation would result in additional carbon sequestration and lower the carbon footprint of a project. x Demolition of existing buildings. Existing buildings have “embedded energy,” related to the energy involved in their initial construction that is then lost when they are demolished. The disposal of demolished building materials may also have GHG emissions related to transport to recycling facilities and other locations, including the disposal of some materials. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 10-12 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT x Construction Activities. Construction equipment typically uses fossil-based fuels to operate. The combustion of fossil-based fuels creates GHGs such as carbon dioxide, methane and nitrous oxide. Furthermore, methane is emitted during the fueling of heavy equipment. Construction activities include demolition and site preparation as well building construction. x Gas, Electric and Water Use. Natural gas use results in the emissions of two GHGs: methane (the major component of natural gas) and carbon dioxide from the combustion of natural gas. Methane is released prior to initiation of combustion of the natural gas (as before a flame on a stove is sparked), and from the small amount of methane that is uncombusted in a natural gas flame. Electricity use can result in GHG production if the electricity is generated by combusting fossil fuel. California’s water conveyance system is energy intensive. Preliminary estimates indicate that total energy used to pump and treat this water exceeds 15,000 GWh per year, or at least 6.5 percent of the total electricity used in the State per year. 35 x Motor Vehicle Use. Transportation associated with development projects would result in GHG emissions from the combustion of fossil fuels in daily automobile and truck trips. However, these emissions would not be “new” since drivers are likely relocated from another area. Also, as discussed previously, the OPSP is designed to limit auto trips. While implementation of the OPSP would lead to the generation of GHG emissions as described above, the BAAQMD and the City of South San Francisco’s anticipated implementation of a Climate Action Plan (which would be expected to include an array of programs and measures) would collectively reduce the levels of GHG emissions and contributions to global climate change attributable to activities throughout South San Francisco. GHG emissions were computed for the full build out scenario of the proposed OPSP. Specifically, construction emissions were computed for the Phase I Project under an assumed approximately 3.5- year construction period, including relocation of landfill materials and landfill cap improvements. As discussed in Chapter 6: Air Quality, the URBEMIS2007 model was used to compute annual air pollutant emissions. The URBEMIS2007 input files were then processed with the new BAAQMD Greenhouse Gas Model (BGM). Emissions model results are included in Appendix B. CONSTRUCTION GHG EMISSIONS Impact GHG-1: Construction-Period GHG Emissions. Temporary construction-related exhaust would be an additional source of GHG emissions that could contribute to significant impacts on the environment. This is a less-than-significant impact. BAAQMD does not have an adopted threshold of significance for construction-related GHG emissions, though recommends quantification using URBEMIS for proposed land use development projects. The URBEMIS2007 modeling conducted for the air quality analysis provided the estimate of construction GHG emissions in the form of CO2. Emissions associated with construction were assumed to all occur in 2012 through 2015. Total construction emissions for the Phase I Project would be 3,787 metric tons of CO2 from construction equipment, truck traffic and associated construction worker traffic over this 3.5 year construction period. Because emissions vary over time based on the actual construction work being completed during any given time-period, the highest annual emissions have been determined to be 979 metric tons of CO2. (See emissions model results in Appendix B for additional detail.)These would be temporary emissions. Emissions associated with construction of the entire OPSP were not 35 California Energy Commission (CEC), 2004. Water Energy Use in California (online information sheet) Sacramento, CA, August 24, http://energy.ca.gov/pier/iaw/industry/water.html, accessed July 24, 2007. CHAPTER 10: GREENHOUSE GAS EMISSIONS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 10-13 computed as the specifics of the construction schedule cannot be known at this time. However, it can be assumed that schedules for construction of future phases of the OPSP would be similar to that for Phase I, with similar annual emissions, though in actually, construction equipment are likely to produce fewer emissions over time to meet increasingly strict regulations, which would result in reduced emissions from those modeled today. In order to determine significance in the absence of a threshold for the construction-period, these emissions of up to 979 metric tons of CO2 annually has been conservatively compared to the operational threshold of 1,100 annual metric tons and determined to be a less-than-significant impact for the construction period. Note that such a comparison is considered very conservative as other jurisdictions divide the construction emission over the anticipated lifetime of the project, instead of looking at the highest year of emissions. Although the impact is less-than-significant, BAAQMD recommends implementation of best management practices to further reduce construction-period GHG emissions. Accordingly, mitigation measure GHG-1 is included below. Mitigation Measure GHG-1: Construction GHG Reduction Measures. The following best practice measures shall be included in construction contracts to reduce GHG emissions during construction, as feasible. x At least 15 percent of the fleet of construction vehicles/equipment shall be alternative fueled (e.g., biodiesel, electric). x At least 10 percent of the building materials shall be locally sourced. x At least 50 percent of construction waste or demolition materials shall be recycled or reused. With the implementation of appropriate reduction measures, impacts related to construction-period GHG emissions would be further reduced from the already less than significant level. OPERATIONAL EMISSIONS Impact GHG-2: Operational Greenhouse Gas Emissions. New development in the OPSP area would be an additional source of GHG emissions, primarily through consumption of energy for transportation and energy usage, which could contribute to significant impacts on the environment. This impact is potentially significant. BAAQMD developed a GHG model referred to as the BAAQMD GHG Model or BGM. BGM is an Excel workbook tool that uses the URBEMIS2007 file to provide GHG emissions in the form of equivalent CO2 emissions (CO2e) in metric tons per year. Unless otherwise noted below, the model defaults for the San Francisco Bay Area were used. The URBEMIS2007 modeling file for the Year 2020 was used in the BGM model. BGM provides emissions for transportation, areas sources, electricity consumption, natural gas combustion, electricity usage associated with water usage and wastewater discharge, and solid waste land filling and transport. Annual emissions in term of metric tons per year are provided in Table 10.2. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 10-14 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Model Year The model uses mobile emission factors from the California Air Resources Board’s EMFAC2007 model. This model is sensitive to the year selected, since vehicle emissions have and continue to be reduced due to fuel efficiency standards and low carbon fuels. The Year 2020 was selected for Phase I Project, since BAAQMD thresholds are based on meeting the AB32 reduction goals by 2020. Full build out of the OPSP would occur around 2035. Traffic Trip generation rates developed for the traffic study were used along with the default trip lengths in URBEMIS2007. Table 10.2: Phase I Project and OPSP Build Out GHG Emissions (in metric tons/year of CO2e) Source Description Phase I Project in 2020 OPSP Build Out in 2035 Transportation (i.e., traffic) 4,267 13,450 Area (e.g., landscape equipment) 1 1 Electricity 1,536 7,062 Natural Gas 505 2,519 Water & Wastewater 48 207 Solid Waste 1,776 8,447 Total (Gross*)8,132 31,686 Number of Employees (Gross*) 1,433 6,821 Annual Metric Tons Per SP 5.67 4.64 * Note that for comparison to the efficiency-based metric, gross emissions and gross employees were used in this analysis rather than net increases. Area Sources The proposed project would be designed to achieve LEED certification. Therefore, energy efficiency would be 20 percent greater than Title 24 standards in place during this analysis (2010). This should be achievable, because development under the OPSP would be subject to the Title 24 amendments to the code that became effective on January 1, 2011. Adjustments were made either in the BGM model or to the model output. These include: x Energy efficiency of the project was assumed to be 20% greater than Title 24 standards; x A minimum waste diversion rate of 50% was assumed; x Emissions associated with electricity consumption output by BGM were adjusted to account for PG&E’s lower emission rate. BGM uses a Statewide rate of 805 pounds of CO2 per megawatt of electricity produced, while the rate for PG&E is at 537 pounds per megawatt. CHAPTER 10: GREENHOUSE GAS EMISSIONS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 10-15 Development under the OPSP would be required to comply with existing City of South San Francisco and the BAAQMD policies and programs that will further reduce the GHG emissions from individual development projects, including: x Energy Efficiency – Projects developed under OPSP are required to comply with all applicable local, state, and federal regulations associated with the generation of GHG emissions and energy conservation. In particular, construction of development under the OPSP is required to meet California Energy Efficiency Standards for Residential and Nonresidential Buildings, and the requirements of pertinent City policies as identified in the City’s Residential and Commercial Energy Conservation Ordinances (RECO and CECO), helping to reduce future energy demand as well as reduce each project’s contribution to regional GHG emissions. The applicant proposes the following energy efficiency measures to meet or exceed Title 24 and CalGreen Code: o A high efficiency glazing to reduce solar heat gain/loss and to maximize daylighting o A curtain wall system “tuned” based upon solar orientation and design to maximize passive solar heating o A cool roof system to reduce solar heat gain and heat island effect o Advance lighting controls for the base building o A garage and service dock is naturally ventilated In addition, the tenant improvements will likely have the following energy efficiency measures which will meet or exceed title 24 and CalGreen: o High performance HVAC systems o High efficiency water heating systems o Advanced lighting controls for tenant spaces As indicated above, the City of South San Francisco has a variety of other policies, programs and actions to address global climate change that will apply to the Oyster Point area. These were discussed above under the existing regulatory environment, and include: x Construction Waste. Any project built in South San Francisco must comply with the City’s Construction and Waste Reduction Ordinance and submit a Construction and Demolition Waste Reduction Plan for review and approval. As a result, construction-related truck traffic (which primarily relies on diesel-fueled engines) would be reduced since some demolition debris hauled off site would be reused on site. In addition, reuse of concrete, asphalt, and other debris will reduce the amount of material introduced to area landfills. x City Standards. Any development project is also subject to all the regulatory requirements including the City’s standard conditions of approval, which would reduce GHG emissions of the project. These include conditions to address adherence to best management construction practices and equipment use. It must also minimize post construction stormwater runoff that could affect the ability to accommodate potentially increased storms and flooding within existing floodplains and infrastructure systems. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 10-16 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT x Transportation Demand Management (TDM) The City of South San Francisco requires that all new nonresidential developments expected to generate 100 or more average daily trips implement a TDM plan to reduce vehicle traffic. The Transportation/Traffic Section of the EIR discusses the various TDM measures that were included in the traffic analysis for the OPSP. The TDM measures as analyzed in the Transportation/Traffic Section of the EIR show a 9.5% reduction in peak hour traffic compared to the existing traffic, while an intensive TDM program will reduce peak hour traffic by an additional 20 to 25%. Projected Service Population The BAAQMD CEQA Guidelines identify an efficiency-based threshold to evaluate emissions associated with projects and plans. This metric is based on the “service population,” which is a combination of projected population and employment associated with the growth projections assumed. Approximately 250 square feet of floor space per employee is a rule of thumb for office uses, though research and development uses would be anticipated to need more space per employee, estimated at 500 square feet per employee. Assuming a 40-percent /60-percent split of Office/Research & Development and 294 employees in the 350 room hotel and 40,000 square foot retail/restaurant uses, this would yield a projection of 1,433 employees for the Phase I Project and 6,821 employees for the full build-out of the OPSP. Note that for comparison to the efficiency-based metric, gross emissions and employees were used in this analysis rather than net increases. The service population for the Phase I Project and full build-out of the OPSP are shown in Table 10.2. Conclusions Annual emissions reported in Table 10.2 are divided by the service population (i.e., number of employees) to evaluate the significance. BAAQMD has identified an efficiency threshold of 4.6 metric tons per capita per year for projects and plans of this type. This threshold has been conservatively used in this analysis even though the analysis was begun before adoption of the threshold, as discussed previously in this chapter. In 2020, the Phase I Project build-out is anticipated to have per-capita emissions of 5.67 metric tons per capita per year. In 2035, build-out of the entire OPSP would have emissions of 4.64 metric tons per capita per year, reflecting the lower transportation-related emission rates. The Phase I Project and OPSP would include many best practices and additional measures to reduce GHG emissions and increase efficiencies, as described previously in this chapter. However, since quantified emissions would be above the 2010 BAAQMD efficiency-based threshold, even though this threshold would not strictly apply to this analysis because it was begun before the threshold was adopted, the impact of GHG emissions from the Phase I Project and full build-out of the OPSP have conservatively been determined to be significant and unavoidable. CONSISTENCY WITH GREENHOUSE GAS REDUCTION PLANS The OPSP is not located in a community with an adopted qualified GHG Reduction Strategy, so consistency with such a plan cannot be analyzed. Emissions associated with the development of the proposed Phase I Project and OPSP were analyzed per the BAAQMD June 2010 CEQA Air Quality Guidelines. BAAQMD’s thresholds and methodologies take into account implementation of state-wide regulations and plans, such as the AB 32 Scoping Plan and adopted state regulations such as Pavley and the low carbon fuel standard. Therefore, there would be no impact in relation to consistency with GHG reduction plans. OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 11-1 11 HAZARDOUS MATERIALS INTRODUCTION A hazardous material is a substance or combination of substances which, because of its quantity, concentration, or physical, chemical or infectious characteristics, may either 1) cause, or significantly contribute to, an increase in mortality or an increase in serious, irreversible, or incapacitating reversible illness; or 2) pose a substantial present or potential hazard to human health and safety, or the environment when improperly treated, stored, transported, disposed of, or otherwise managed. Hazardous waste (a subset of hazardous materials) refers to hazardous material that is abandoned, discarded or recycled.

REGULATORY SETTING CALIFORNIA CODE OF REGULATIONS, TITLE 27, DIVISION 2 The primary design and construction standard related to the presence of landfill waste at the OPSP area is Title 27 of the California Code of Regulations (CCR), Division 2 (Solid Waste). The two state DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 11-2 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT regulatory agencies cited in Title 27 CCR Division 2 are the State Water Resources Control Board (SWRCB) and the California Integrated Waste Management Board (CIWMB). The San Mateo County Health Services Agency (SMCHSA) – Environmental Services Division is the Local Enforcement Agency (LEA) as per Title 27 CCR Section 2005. BAY AREA AIR QUALITY MANAGEMENT DISTRICT The Bay Area Air Quality Management District (BAAQMD) is responsible for monitoring site operations that affect air quality. Air pollution control measures at the site are directed towards minimizing fugitive dust emissions and controlling landfill gas (LFG) migration. Regulation 8, Rule 34 requires all landfill operators to collect and process landfill gas. Based on estimates that the entire landfill exceeds one million tons of refuse, Regulation 8, Rule 34 would require the City of South San Francisco to reduce emissions of methane and non-methane organic compounds from the waste decomposition process at Oyster Point Landfill. However, the site should qualify for an exemption from Regulation 8, Rule 34 (8-34-110) because it meets the following criteria: x It is a closed or inactive landfill, and has no design capacity available for future refuse deposition, x It last received waste at least 30 years ago (1970), and x The owner has demonstrated that the site does not pose a health risk to the public health and safety, nor does it threaten the environment under the California Health and Safety Code, Section 41805.5. In order to be exempt from BAAQMD Regulation 8 Rule 34, the City of South San Francisco shall submit a Design Capacity Report to BAAQMD. It is assumed that the development site will not need an active LFG collection and treatment system. However, it is assumed that the buildings shall require, at a minimum, a passive LFG venting system, which would need to have the capacity to be retrofitted to an active system by the addition of blowers. Therefore, a new emission source for the proposed development for the emitting gases collected under the hotel foundation would be reviewed under BAAQMD Regulation 8 Rule 2 as a general organic emission source and Regulation 2 Rule 5 as a new source of toxic air contaminants. An Application for Authority to Construct/Permit to Operate (form P-101B) shall be necessary to file a minimum of 30 days prior to construction in order to coordinate and document regulatory exemption. REGIONAL WATER QUALITY CONTROL BOARD - SAN FRANCISCO The landfill portion of the OPSP site previously operated under Waste Discharge Requirements issued by the RWQCB. The RWQCB issued on June 21, 2000 Order No. 00-046 – Updated Waste Discharge Requirements and Recision of Order No. 77-19 for City of South San Francisco Oyster Point Landfill, South San Francisco, San Mateo County. SAN MATEO COUNTY HEALTH SERVICES AGENCY The SMCHSA, as the LEA, is responsible for enforcement of the final closure and post-closure maintenance activities of the landfill under Title 27 CCR Chapter 1, Section 20005, as overseen by the CIWMB, including items related to LFG control and monitoring. Approval of the final post- closure development application by the LEA is required prior to site construction. Details for these planned closure and post-closure actions for the entire Oyster Point Landfill, including the OPSP area, are provided by in the Final Closure and Post-Closure Maintenance Plan (PCMP) (Gabewell, 2000). CHAPTER 11: HAZARDOUS MATERIALS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 11-3 CITY OF SOUTH SAN FRANCISCO The City of South San Francisco Planning, Engineering, and Building Divisions shall review all architectural, structural, civil, electrical, and landscape plans and specifications associated with the entire development. Typically a City Fire Department shall review and approve the LFG monitoring and alarm systems within the buildings as well. In addition, the City of South San Francisco General Plan contains several policies that relate to hazardous materials and waste, mainly contained in General Plan Section 8.3, shown in Table 11.1. Table 11.1: Select General Plan Policies Regarding Hazardous Materials Policy Goal 8.3-G-1 Reduce solid and hazardous waste, and recycle to slow the filling of landfills in accord with the California Integrated Waste Management Act of 1989. 8.3-G-2 Enforce revised zoning ordinance prohibition of intensive industrial production of hazardous waste and the permanent storage of hazardous materials. Limit light industrial uses that produce hazardous waste, such as auto repair and auto painting businesses. 8.3-I-3 Establish a Geographic Information Systems (GIS) database of sites included on the Cortese List. The GIS should assist in the development approval process. 8.3-I-4 Establish an ordinance specifying routes for transporting hazardous materials. Routes should not pass through residential areas or other sensitive areas and allow specific times for transport to reduce the impact and accident risk during peak travel periods. Source: City of South San Francisco General Plan OTHER REGULATIONS, PLANS AND PROGRAMS The Hazardous Materials Business Plan is used to keep track of the use of hazardous materials by businesses in accordance with both state and federal laws. The California Accidental Release Prevention (CalARP) Program is a merging of the federal and state programs for the prevention of accidental release of regulated toxic and flammable substances. The goal is to eliminate the need for two separate and distinct chemical risk management programs. CalARP is the Federal Risk Management Plan Program with additional state requirements, including a list of regulated substances and thresholds and requires preparation of a Risk Management Plan for businesses using regulated substances. The Hazardous Waste Generator Program was started in 1984 when the State of California DTSC authorized the Health Department to inspect and regulate non-permitted hazardous waste generators in San Mateo County based on the Hazardous Waste Control Law found in the California Health and Safety Code Division 20, Chapter 6.5 and regulations found in the CCR, Title 22, Division 4.5. The groundwater protection program is funded wholly or in part, by the United States Environmental Protection Agency (USEPA), under Cooperative Agreement L-009450-1-0 to the State Water Resources Control Board (SWRCB) and by Contract 8-014-550 to the County of San Mateo. In conjunction with these laws the underground storage tank program was created to regulate the chief source of underground contamination, leaking underground storage tanks (LUSTs) or fuel tanks (LUFTs). Many regulatory agencies maintain a database of sites. Currently, both the DTSC (www.envirostor.dtsc.ca.gov) and State Water Resources Control Board (geotracker.swrcb.ca.gov) DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 11-4 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT maintain online searchable databases of hazardous materials sites. Other databases with information on hazardous materials sites include the Federal Superfund list started through the Comprehensive Environmental Response, Conservation, and Liability Act (CERCLA) of 1980 and the USEPA, the Comprehensive Environmental Response, Compensation, and Liability Information System (CERCLIS), HAZNET, the leaking underground storage tank information system (LUST), and the Cortese list. Air pollution is regulated through the Bay Area Air Quality Management District (BAAQMD). These programs and regulations are intended to restrict environmental contamination, including hazards to wildlife, provide protection for natural resources, and limit public exposure to harmful chemicals. Specific programs intended to protect workers from exposure to hazardous materials and from accidental upset are covered under the Occupational Health and Safety Administration at both the Federal Level (OSHA) and the state level (CAL-OSHA). Title 40 of the Federal Code of Regulations covers worker training and safety regulations pertinent to hazardous materials. OSHA regulations for hazardous waste operations training in California are found in both the Code of Federal Regulation 29CFR, Section 1910.120(e) and CCR Title 8, General Industry Safety Orders (GISO) 5192. The law requires General Site Workers receive a minimum of 40 hours of instruction off the site, and a minimum of three days of actual field experience, while Occasional Site Workers receive a minimum 24 hours of instruction off the site, and a minimum of one day actual field experience. Transportation of hazardous materials on the highways is regulated primarily through the Federal Department of Transportation (DOT) and the California Department of Transportation (CALTRANS). This includes a system of placards, labels, and shipping papers required to identify the hazards of shipping each class of hazardous materials. Existing federal and state laws address risks associated with the transport of hazardous materials. These laws include regulations outlined in the Hazardous Materials Transportation Act administered by the DOT. Caltrans is mandated to implement the regulations established by the DOT, which is published as the Code of Federal Regulations, Title 49, commonly referred to as 49 CFR. The California Highway Patrol (CHP) enforces these regulations. Regulations of hazardous materials and wastes include the manufacture of packaging and transport containers; packing and repacking; labeling; marking or placarding; handling; spill reporting; routing of transports; training of transport personnel; and registration of highly hazardous material transport. SETTING SITE HISTORY Prior to the development of the Oyster Point landfill in the 1950’s, the San Francisco Bay shoreline was located at the west end of the OPSP area. West of the original shoreline there was a low shale and sandstone bluff which comprised a portion of the original Oyster Point. Following the 1957 enactment of laws prohibiting open air burning of rubbish in the Bay Area, plans were made to establish a solid waste disposal site on the submerged lands just east of the original Oyster Point. The landfill was developed in three phases. The first area to be filled extended about 1,500 feet eastward from the original bluff. Filling of the first section began in 1957 and was completed by late 1961. In 1962, a small craft harbor was constructed along the north shore of the landfill. To create a filled breakwater for the east side of the marina, the second phase of landfill was placed in the form of a mole extending from the eastern end of the first fill and north about 400 feet into the bay. The third phase of filling began in 1964 and was accomplished by dredging up Bay Mud and forming mud dikes and a dike-enclosed cell in which solid waste was later placed. CHAPTER 11: HAZARDOUS MATERIALS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 11-5 The Oyster Point Landfill was in operation from 1957 to 1970. Landfill closure activities were conducted from 1970 to 1981 and in 1987. The RWQCB has historically been the LEA regulating the landfill. The RWQCB issued Order No. 00-046 – Updated Waste Discharge Requirements and Recision of Order No. 77-19 for City of South San Francisco Oyster Point Landfill, South San Francisco, San Mateo County on June 21, 2000. This document updated the 1977 self-monitoring and closure program for the landfill. The Updated Waste Discharge Requirements apply only to the landfill portion of the OPSP. The landfill is currently owned by the City of South San Francisco and is operated as a marina, ferry terminal, hotel, office space and open space. The City of South San Francisco and the San Mateo County Harbor District hold responsibility for landfill maintenance pursuant to a Joint Powers Agreement. Portions of the OPSP area are outside the boundaries of the former landfill. VICINITY HAZARDOUS MATERIALS SITES There are numerous hazardous materials sites throughout the area east of Highway 101 in South San Francisco, reflecting the long industrial history of the area. Due to the density of sites, only those within or bordering the OPSP area are discussed here since potential contamination from these adjacent sites would have the greatest potential impact during development of the site. The sites were identified in the Geotracker and Envirostor databases, which are maintained by SWRCB and DTSC respectively, as shown in Table 11.2. Table 11.2: Vicinity Hazardous Materials Sites NAME/ADDRESS CONTAMINANTS OF CONCERN POTENTIAL MEDIA AFFECTED CASE STATUS/DATE DATABASE Oyster Cove Marina 385 Oyster Point Blvd. Gasoline Soil Closed as of 10/12/1994 Geotracker - Luft Seaboard Paper Co. 336 Oyster Point Blvd. Gasoline Groundwater (non-drinking water) Closed as of 11/1/1995 Geotracker - Luft Wildberg Bros 349 Oyster Point Blvd. Gasoline Soil Closed as of 7/17/2001 Geotracker - Luft Wildberg Bros 349 Oyster Point Blvd. Arsenic, lead, antimony and compounds, mercury and compounds, nickel Soil Certified as of 11/30/1987 5-yr review on 11/28/1995 confirmed No Further Action status Envirostor – Voluntary Cleanup The facility at 349 Oyster Point Blvd. is located adjacent to the OPSP area. While all of the sites are identified as having prior releases of hazardous materials, there is no reported evidence available from the databases of active leaks or contamination from these sites affecting soil or groundwater that could migrate to the OPSP area or represent significant releases in the OPSP area requiring any additional actions. Given the closed status of sites, any residual or off-site contamination would likely be secondary to the contamination present on the OPSP area from the landfill. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 11-6 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT In addition, the 2006 Draft EIR for the Ferry Terminal (EIP Associates, 2006) presented search information obtained from Environmental Data Resources, Inc. for a wider variety of regulatory databases. Databases containing information for sites on or immediately adjacent to the OPSP area include: CERCLIS-NFRAP - Comprehensive Environmental Response, Compensation, and Liability Information System – No Further Response Action Planned ERNS Emergency Response Notification System RCRIS-LQG & RCRIS SQG - Resource Conservation and Recovery Information System Large & Small Quantity Generators. CHMIRS California Hazardous Material Incident Report System CORTESE:Contains listing for LUST (Leaking Underground Storage Tank), SWF/LS, and Cal- Sites databases. SWF/LF Solid Waste Information System CA FID Facility Inventory Database of USTs HAZNET: Hazardous Waste Database. VCP:Voluntary Cleanup Program Files were also obtained directly from the South San Francisco Fire Department and the San Francisco Bay RWQCB. The Ferry Terminal Draft EIR (EIP, 2006) contained the following information regarding facilities located on or immediately adjacent to the current OPSP area (see Figure 3.3 in Chapter 3: Project Description for exact locations): Former Landfill (within the OPSP) – “Listed on the CERC-NFRAP database. This listing is due to the closed, unlined Class III landfill that extends across the project site. Listing on this database indicates that the site was determined not to be eligible for listing on the NPL. Status of the landfill is closed, meaning that the landfill is no longer accepting waste and that it is covered with a cap. An order was issued by the San Francisco Bay Regional Water Quality Control Board (RWQCB) in response to a previous proposed development (Order No. 00-046 issued June 21, 2000). The order imposes new closure and post-closure requirements on the City as part of future development. New closure and post-closure requirements are presented to ensure that future development and construction activities at the site: › Maintain the landfill cap and cutoff wall integrity › Minimize settlement-induced leachate generation › Prevent hazardous accumulations of landfill gas › Inhibit migration of leachate and landfill gas In addition, quarterly monitoring of subsurface landfill conditions is ongoing. Further investigation could be required by the RWQCB in such instances as a proposed change in land use, proposed development activities, or if a release from the landfill is discovered. As CHAPTER 11: HAZARDOUS MATERIALS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 11-7 such, a Development (or Redevelopment) Proposal shall be submitted to the RWQCB in accordance with Order No. 00-046 for the project site. › The Ferry Terminal Draft EIR (EIP, 2006) indicated that several areas of the landfill cover did not meet Title 27 requirements. The areas are indicated in Figure 9 of the Geotechnical Investigation of the Landfill Cover (Treadwell & Rollo, 2009b), and include three different potential deficiencies, 1.Six areas where the landfill cover thickness is less than 4 feet 2.Four areas where a low hydraulic conductivity layer thickness is less than 1 foot thick 3.One area where permeability of low hydraulic conductivity is greater than 1 x 10-6 cm/sec 671 Marina Boulevard (within the OPSP)—“Listed as a small quantity generator of hazardous waste. This facility has been occupied by various boat sales and maintenance companies since its construction. Based on San Mateo County Health Department—Environmental Health Division (SMCHDEHD) records reviewed, wastes reported to have been generated at this facility in the past include waste oil, oily debris/filters, Safety Kleen solvent, waste acetone, waste coolant, and glycol. These wastes were generated during boat maintenance activities. Waste oil was formerly stored within a 350-gallon AST at this facility. Solvent storage sinks were formerly located within the service areas. Waste acetone was stored within a 55-gallon drum. The EDR indicates that no violations were reported in connection with hazardous waste management at this facility. Safety Kleen solvent is no longer used at this facility. Corrections noted in the most recent SMCHDEHD inspection (2000) of this facility include disposing of all unused chemicals (lube oil, batteries, diesel, gasoline, acetone), providing housekeeping beneath compressors, storing batteries and drums under cover, and not allowing soapy water to enter the storm drain. These corrections have been implemented”. In addition the site had “a release of 50 gallons of propane from a loose fitting on a propane tank.” 95 Harbor Master Road (within the OPSP)—“Eight incidents were listed in the ERNS. These incidents included: › A reported oily sheen on the eastern end of the launch ramp in 2002 › A release of one-half cup of diesel fuel into the bay during replacement of fuel lines at the fuel dock in 2000 (cleaned up using absorbents and booms) › A release of two pounds of diesel in 1992 (contained using booms) › A release of hydraulic oil from a bilge pump of a vessel due to the rain in 2000 (remediated using booms and absorbents) › A 40-foot sheen of fuel from a sunken sailboat in 1998 (remediated using booms) › Two other listings for 95 Harbor Master Road did not provide details” In a separate database, there was a report of “an unknown sheen extending from a boat that sunk was reported in November 2002.” DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 11-8 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT 925 Marina Boulevard, 671 Marina Boulevard, & 1 Harbor Master Road (within the OPSP) —Based “on information provided in the EDR report, wastes transported from the site for off site disposal include organic solids; unspecified organic liquid mixture; waste oil and mixed oil; oil containing waste; hydrocarbon solvents; aqueous solution with less than 10% total organic residues; off-specification, aged, or surplus organics; and oxygenated solvents. During the most recent site visit, wastes observed to be stored at the site were within the used oil collection area and within the yard of the Harbor District maintenance building. Drums containing monitoring well purge water, one drum containing waste oil, and two totes containing waste oil were observed in the yard. Limited staining has occurred at the base of the drum and totes; however, it is limited to the surface of the asphalt.” 384 Oyster Point Boulevard (within the OPSP)— “According to records reviewed, a UST was formerly located to the south of this facility, near the northern boundary of the project site. This UST was 1000 gallons in capacity and was formerly used for a generator at this facility. This UST was removed in August 2002. No releases from the UST were noted.” 385 Oyster Point Boulevard (within the OPSP) - “Based on SMCHDEHD records reviewed, facilities currently and formerly located at this facility that generate/store hazardous waste include Oyster Cove Marina, Oxon Media, Intervention Therapeutics Corporation, AXYS Pharmaceuticals, ChemRX, and Morrow Services. Waste solvent, waste flammable liquids, waste corrosive liquids, and medical waste were reported to be generated. No significant concerns or releases were noted in hazardous waste management records for this facility. project site, based on the data available.” According to alternate database information for the site “two 350-gallon waste oil USTs were removed from this facility in July 1992. Based on confirmation samples, these locations were over excavated in August 1992. Two monitoring wells were installed and monitored for four quarters. Groundwater was below detection limits for four quarters for total petroleum hydrocarbons as diesel (TPH-d), total petroleum hydrocarbons as motor oil (TPH-mo), and total oil and grease (TOG). The LUST case was granted closure in October 1994.” 375 Oyster Point Boulevard (within the OPSP) —“No violations were reported in connection with hazardous waste management at this facility. This facility was not listed on any databases searched by EDR that indicate that a release has occurred.” 349 Oyster Point Boulevard (adjacent to the OPSP)—“Based on records reviewed for this facility, a fuel oil UST was removed from this facility in 1982. In 1997, during construction activities, impacted soil from the UST was discovered under a concrete slab. According to a case closure memorandum, the groundwater beneath this facility does not have appreciable beneficial uses due to its natural salinity from its proximity to the bay. The soil was excavated and the LUST case for this facility was closed in July 2001. Its listings on the VCP database are likely due to the former use of this facility as a metals refining/metals recovery facility. Elevated metals (zinc, nickel, and antimony) were reported in groundwater beneath this facility. Remedial actions included dredging the lagoon on the northern portion of this facility, sludge removal, filling the lagoon with clean soil, and removal of a slag pile. Groundwater monitoring at this facility indicted that groundwater flowed to the north, towards the Bay. Elevated metal concentrations in groundwater do not appear to extend to the south of this facility, towards the project site, based on the data available.” CHAPTER 11: HAZARDOUS MATERIALS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 11-9 IMPACTS AND MITIGATION MEASURES STANDARDS OF SIGNIFICANCE The following thresholds for measuring a project’s environmental impacts are based upon CEQA Guidelines thresholds: 1. Would the project create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? 2. Would the project create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? 3. Would the project produce hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? 4. Would the project be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment? 5. Would the project be located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport? Would the Project result in a safety hazard for people residing or working in the Project Area? 6. For a project within the vicinity of a private airstrip, would the Project result in a safety hazard for people residing or working in the Project Area? 7. Would the project impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan? 8. Would the project expose people or structures to a significant risk of loss, injury or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands? HAZARDOUS MATERIALS USE, TRANSPORT This section pertains to recurring transportation, use or disposal of hazardous materials as part of long term site activities. One time transportation, use or disposal of hazardous materials related to construction and development is discussed in the following sections. Impact Haz-1: Routine transportation, use or disposal of hazardous materials. While specific tenants have not yet been identified, research laboratories are likely to handle materials considered to be biological hazards, chemical hazards and/or carry a risk of fire or explosion. The risk of accidental upset and environmental contamination from routine transport, storage, use and disposal of hazardous and potentially hazardous materials to the public and environment is a potentially significant impact. The proposed development includes construction of office buildings and research laboratories. Depending upon the specific nature of research planned at the proposed facilities, which has not yet been determined, there are likely to be both hazardous and potentially hazardous materials stored and used on the site that will eventually require disposal. There are likely to be biological hazards, chemical hazards and risk of fire or explosion. There is also likely to be transportation of hazardous materials to and from the site, probably traveling along Highway 101 and Oyster Point Boulevard. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 11-10 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Mitigation Measures Haz-1a: Plan Review for Adherence to Fire and Safety Codes. Building space shall be designed to handle the intended use, with sprinklers, alarms, vents, and secondary containment structures, where applicable. These systems shall pass plan review through the City of South San Francisco Planning, Building and Fire Departments. Haz-1b: Construction Inspection and Final Inspection Prior to Occupancy. During construction, the utilities including sprinkler systems shall pass pressure and flush tests to make sure they perform as designed. At the end of construction, occupancy shall not be allowed until a final inspection is made by the Fire Department for conformance of all building systems with the Fire Code and National Fire Protection Agency Requirements. The inspection shall include testing of sprinklers systems, alarm systems, ventilation and airflow systems, and secondary containment systems. The inspection shall include a review of the emergency evacuation plans. These plans shall be modified as deemed necessary. Haz-1c: Hazardous Materials Business Plan Program. Businesses occupying the development shall complete a Hazardous Materials Business Plan for the safe storage and use of chemicals. The Business Plan shall include the type and quantity of hazardous materials, a site map showing storage locations of hazardous materials and where they may be used and transported from, risks of using these materials, material safety data sheets for each material, a spill prevention plan, an emergency response plan, employee training consistent with OSHA guidelines, and emergency contact information. Businesses qualify for the program if they store a hazardous material equal to or greater than the minimum reportable quantities. These quantities are 55 gallons for liquids, 500 pounds for solids and 200 cubic feet (at standard temperature and pressure) for compressed gases. Exemptions include businesses selling only pre-packaged consumer goods; medical professionals who store oxygen, nitrogen, and/or nitrous oxide in quantities not more than 1,000 cubic feet for each material, and who store or use no other hazardous materials; or facilities that store no more than 55 gallons of a specific type of lubricating oil, and for which the total quantity of lubricating oil not exceed 275 gallons for all types of lubricating oil. These exemptions are not expected to apply to on-site laboratory facilities. Businesses occupying and/or operating at the proposed development shall submit a business plan prior to the start of operations, and shall review and update the entire Business Plan at least once every two years, or within 30 days of any significant change, including without limitation, changes to emergency contact information, major increases or decreases in hazardous materials storage and/or changes in location of hazardous materials. Plans shall be submitted to the San Mateo County Environmental Health Department (SMCEHD) Business Plan Program, which may be contacted at (650) 363-4305 for more information. The SMCEHD shall inspect the business at least once a year to make sure that the Business Plan is complete and accurate. Haz-1d: Hazardous Waste Generator Program. Qualifying businesses shall register and comply with the hazardous waste generator program. The State of California DTSC authorized the SMCEHD to inspect and regulate non-permitted hazardous CHAPTER 11: HAZARDOUS MATERIALS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 11-11 waste generators in San Mateo County based on the Hazardous Waste Control Law found in the California Health and Safety Code Division 20, Chapter 6.5 and regulations found in the CCR Title 22, Division 4.5. Regulations require businesses generating any amount of hazardous waste as defined by regulation to properly store, manage and dispose of such waste. SMCEHD staff also conducts surveillance and enforcement activities in conjunction with the County District Attorney's Office for businesses or individuals that significantly violate the above referenced law and regulations. Haz-1e: Compliance with Applicable Laws and Regulations. All transportation of hazardous materials and hazardous waste to and from the OPSP area shall be in accordance with CFR Title 49, US Department of Transportation (DOT), State of California Department of Transportation (Caltrans), and local laws, ordinances and procedures including placards, signs and other identifying information. Implementation of the above mitigation measures for uses handling hazardous materials in the OPSP, including office/R&D buildings as part of the Phase I Project, would reduce the impact of routine transportation, use or disposal of hazardous materials to a level of less than significant through compliance with existing regulations, plans and programs as discussed specifically in mitigation measures Haz-1a through Haz-1e that act to ensure adequate safety levels are reached and maintained throughout the life of the OPSP. ACCIDENTAL HAZARDOUS MATERIALS RELEASE The OPSP area was formerly a municipal landfill, and is proposed to be developed as a multi-use area including biotechnology research, office, hotel, commercial/retail and open space. As such, there are potential hazardous materials release concerns related to the former use and to the proposed future uses of the OPSP area. Construction-Period Impact Haz-2: Accidental Hazardous Materials Release During Disturbance of Landfill Materials.Site preparation and construction activities in the vicinity of the landfill could result in release of hazardous solid waste, groundwater and/or soil vapor and the potential for direct exposure to workers engaged in soil excavation and dewatering activities. This represents a potentially significant impact. The majority of the waste disposed of at the landfill was municipal, non-hazardous, material. However decomposing organic waste generates methane and areas of hazardous materials in the subsurface have been encountered, primarily related to two mapped sumps. In addition, hazardous household wastes (i.e., paint cans) have been found during trenching activities. Contaminants in groundwater (leachate) have been identified at the site. Redevelopment plans include site grading, construction of a sub-grade parking structure, and installation of utility trenches, which will involve excavation of landfill waste material. Excavated non-hazardous waste will be relocated on-site. Excavated hazardous waste would be removed from the site and transported for appropriate off-site disposal. Parking structure installation will likely require construction dewatering of the subgrade. Soil gases, primarily methane, have been identified at the site at levels exceeding the lower explosive limit (LEL). Mitigation Measure Haz-2: Waste Excavation and Re-disposition. A plan shall be written for management of excavated wastes/refuse. Non-hazardous excavated waste shall be re-deposited DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 11-12 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT in an alternate part of the site and any hazardous waste shall be relocated off-site for appropriate disposal. The plan can be a section of the Site Management Plan (Mitigation Measure Haz-4a), or a stand alone document. The plan shall include measures to avoid releases of wastes or waste water into the environment and to protect workers and the public. The details of the plan shall be based, in part, on the amount of material to be removed and the final design of foundation structures, but will generally include the following, as deemed appropriate by the regulatory agencies, particularly DTSC and RWQCB: x To the greatest extent possible, use existing boring data to obtain pre- characterization of refuse for off-site disposal, and to pre-plan areas to be removed versus areas to be re-deposited on-site. x Divide excavation areas into daily sections; plan to complete excavation and backfilling a section during each working day. Minimize the time period that refuse is exposed. x Review existing boring data and existing site documentation to evaluate potential subsurface materials to be encountered. x Stake out area to be excavated. x If excavation is to be conducted at depths where groundwater is to be encountered, conduct dewatering to minimize worker potential direct contact with groundwater. Removed groundwater shall be treated in accordance with the requirements outlined in the Site Management Plan (Mitigation Measure Haz-4a). x Screen excavation site with a portable photoionization detector and combustible gas monitor for landfill gasses. Continue screening progress of each excavation section as work proceeds. Use foam suppressants or 6 inches minimum of daily soil cover for nuisance odors. x Provide carbon dioxide gas source (fire extinguisher or cylinder) to flood excavation as necessary to prevent migration of gases into atmosphere above excavation, minimize explosive or fire potential, and control nuisance and odors. x Begin excavation and segregate soil and /or clay cap material above refuse for reuse as foundation layer. x Upon reaching refuse, place refuse into dump truck standing by on-site. x Dispose of each truck load of refuse immediately after filling equipment. All loads to be covered when hauling. Refuse shall be either re-deposited on-site in a specified area, or hauled to an off-site disposal facility. x Prior to relocation, field verify each load for disposal classification type (landfill classification, Class 3 or Class 2). If waste for off-site disposal is characterized as either California or Federal Hazardous Waste as defined in the criteria described in CCR Title 22 Section 66261, then the hazardous waste shall be tracked using the Uniform Hazardous Waste Manifest System (USEPA Form 8700-22). x Hazardous and if necessary, non-hazardous waste shall be transported to the appropriate disposal facility using a permitted, licensed, and insured transportation company. Transporters of hazardous waste shall meet the CHAPTER 11: HAZARDOUS MATERIALS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 11-13 requirements of 40 CFR 263 and 22 CCR 66263. Copies of uniform hazardous waste manifests signed by the designated waste disposal facility shall be retained for at least five years from the date the waste was accepted by the initial transporter. Copies of records pertaining to the characterization of hazardous or nonhazardous waste shall be retained for a minimum of three years. x Upon reaching over-excavation depth, place a minimum of 6-inch thick layer of appropriate backfill soil on excavation bottom to seal exposed refuse surface. Place soil by the end of the same day excavation is completed. x Upon completion of excavation, begin cap placement procedures. Specific measures shall be targeted to minimize the duration of waste exposure, plan for appropriate final destination of wastes based on the presence of contaminants of concern, allow for adjustment in plan based on unexpected occurrences, and to protect worker safety and the public. Additional work plan measures are discussed in Haz-4a. In addition, worker protection measures for soil and dewatering are discussed in Haz-6a. Measures specific to off-site air quality during construction are included in mitigation measure Air-4. Implementation of mitigation measure Haz-2 would reduce the impact related to accidental hazardous materials release during disturbance of landfill materials to a level of less than significant through implementation of measures to avoid releases of wastes or waste water into the environment and to protect workers and the public during excavation and re-disposition of landfill materials, which is anticipated to occur during the Phase I Project and may also occur during subsequent construction activities at the landfill site, such as buildout of the hotel site. Impact Haz-3: Accidental Release of Hazardous Building Materials. During demolition of existing buildings, hazardous building materials could be released from structures at the site. These represent potentially significant impacts. Mitigation Measure Haz-3: Demolition Plan and Permitting. A demolition plan with permit applications shall be submitted to the City of South San Francisco Building Department for approval prior to demolition. Prior to obtaining a demolition permit from the Bay Area Air Quality Management District (BAAQMD), an asbestos demolition survey shall be conducted in accordance with the requirements of BAAQMD Regulation 11, Rule 2. Prior to building demolition, hazardous building materials such as peeling, chipping and friable lead-based paint and asbestos containing building materials, if identified on the site, shall be removed in accordance with all applicable guidelines, laws, and ordinances. The Demolition Plan for safe demolition of existing structures shall incorporate recommendations from the site surveys for the presence of potentially hazardous building materials, as well as additional surveys if required by the City. The demolition plan shall address both on-site Worker Protection and off-site resident protection from both chemical and physical hazards. Contaminated building materials, if identified, shall be tested for contaminant concentrations and shall be disposed of to appropriate licensed landfill facilities. The Demolition Plan shall include a program of air monitoring for dust particulates and attached contaminants, as merited by the surveys. The need for dust control and suspension of work during dry windy days shall be addressed in the plan. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 11-14 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Implementation of mitigation measure Haz-3 would reduce the impact related to accidental release of hazardous building materials to a level of less than significant through compliance with existing regulations and permitting requirements to ensure any hazardous building materials in structures to be demolished are identified and removed safely. This would be applicable to any buildings demolished as part of the Phase I Project or subsequent phases of development under the OPSP. Post-Construction and Operations Impact Haz-4: Accidental Future Hazardous Materials Release of Pre-existing Site Materials.Landfill materials, which include hazardous materials in solid waste, groundwater and soil vapor, shall remain on-site following construction. Installation of new structures presents the potential for build up of soil gasses within the structures, posing a risk to building occupants and additional loading of the site surface could increase the rate of on-site waste settlement, leading to off-site migration of leachate. This represents a potentially significant impact. As discussed above, there are both known and potential hazardous solid materials in the landfill and contaminants in the groundwater (leachate). Increasing development on the site could lead to an increased rate of on-site waste settlement and off-site migration of leachate. Additionally, soil gases, primarily methane, have been identified at the site at levels exceeding the lower explosive limit (LEL). A series of passively vented landfill gas recovery trenches were installed in 2007 with the goal of decreasing methane levels in the soil. Installation of new structures presents the potential for build up of soil gasses within the structures, posing a risk to building occupants. (The landfill cap upgrades referred to as mitigation measure Haz-4a are included as part of the Phase I Project.) Mitigation Measures Haz-4a: Landfill Cap Upgrades. A landfill cap currently exists to prevent exposure of the public to impacted solids or groundwater. The cap shall be repaired and upgraded to meet CCR Title 27 requirements. CCR Title 27 requires closed landfills have a minimum 4 foot cap, consisting of a 2 foot base layer, a 1 foot clay layer with specified low hydraulic conductivity and a 1 foot erosion control layer. The minimum 4 feet of clean material that comprises the cap shall prevent exposure of the underlying material, preventing releases at the surface. The low hydraulic conductivity layer shall also act to minimize generation of leachate. Haz-4b: Use Of Deep Foundations To Prevent Load Induced Settlement. Buildings on fill shall be supported using driven steel or concrete piles founded in stiff to hard clays, dense sands or weathered bedrock underlying the fill.Both the structural loads and building floor slabs shall be supported on piles. This will avoid placing additional building loads on fill material. Haz-4c: Minimization of Irrigation Water Use. Landscaping of the site shall be selected to stabilize the soil, prevent erosion, and reduce the need for extensive irrigation. Excessive water could infiltrate the landfill cap and produce leachate. To prevent this, low-water vegetation shall be selected to reduce irrigation water. In addition the thickness of the erosion resistant layer in landscaped areas will be increased to minimize intrusion of roots into the lower layers of the cover. Haz-4d: Monitoring for Leachate Migration. A series of natural and man-made barriers have been implemented to prevent migration of impacted leachate into the surrounding area. Based on monitoring at the site implemented per the PCMP, these measures are currently effective in preventing releases. Leachate shall CHAPTER 11: HAZARDOUS MATERIALS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 11-15 continue to be monitored, as discussed in Haz-4e, below. Leachate containment for the landfill portion of the OPSP shall be upgraded as needed during and following construction, as per the requirements of RWQCB Order No. 00-046 and the PCMP. Haz-4e: Operation and Maintenance Activities. Operation and maintenance (O&M) activities are expected to occur indefinitely at the site. Operation and maintenance activities shall include inspections and observations of site features to protect the landfill cap, prevent utility damage, maintain gravity flow of sewer systems, maintain the landfill gas barrier and venting systems, and monitor for leachate and groundwater contaminant concentrations. O&M shall act to prevent releases of hazardous materials by identifying deficits in engineering controls prior to release events. Mitigation measures Haz-4a through Haz-4e include measures to reduce the risk of future releases related to the existing landfill materials that will reduce the OPSP’s impact related to accidental future hazardous materials release of pre-existing site materials to a level of less-than-significant.These measures would be applicable to any development on the landfill site including portions of the Phase I Project as well as subsequent phases under the OPSP, such as development on the hotel site. Impact Haz-5: Accidental Hazardous Materials Release of Laboratory Chemicals. Following construction, operations at the proposed facilities are expected to represent a continuing threat to the environment through accidental release of hazardous materials since the site is proposed to include laboratory facilities, where hazardous materials stored or used on site could lead to an accidental release. This represents a potentially significant impact. Mitigation Measure Haz-5: California Accidental Release Prevention Program (CalARP). Future businesses at the development shall check the state and federal lists of regulated substances available from the SMCEHD. Chemicals on the list are chemicals that pose a major threat to public health and safety or the environment because they are highly toxic, flammable or explosive. Businesses shall determine which list to use in consultation with the SMCEHD. Should businesses qualify for the program, they shall complete a CalARP registration form and submit it to SMCEHD. Following registration, they shall submit a Risk Management Plan (RMP). RMPs are designed to handle accidental releases and ensure that businesses have the proper information to provide to emergency response teams if an accidental release occurs. All businesses that store or handle more than a threshold quantity (TQ)1 of a regulated substance shall develop a RMP and follow it. Risk Management Plans describe impacts to public health and the environment if a regulated substance is released near schools, residential areas, hospitals and childcare facilities. RMPs shall include procedures for keeping employees and customers safe, the handling regulated substances, staff training, equipment 1 California Code of Regulations; Title 19. Public Safety; Division 2. Office of Emergency Services; Chapter 4.5 California Accidental Release Prevention (CalARP) Program, § 2770.5. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 11-16 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT maintenance, checking that substances are stored safely, and responding to an accidental release. Implementation of this mitigation measure Haz-5 for uses handling hazardous materials in the OPSP, including office/R&D buildings as part of the Phase I Project, would reduce the OPSP’s impact related to Accidental Release of Laboratory Chemicals to a level of less-than-significant through compliance with the California Accidental Release Prevention Program including implementation of Risk Management Plans as appropriate. HAZARDOUS MATERIALS NEAR SCHOOLS The OPSP area is not located within one-quarter mile of a school site. Therefore the OPSP, including the Phase I Project, would have no impact based on proximity to school sites. HAZARDOUS MATERIALS SITES The site has a well-documented history of use as a municipal landfill, including the use of two sumps for disposal of liquid wastes including hazardous materials. In addition, there have been a variety of historic and active USTs and ASTs on site. A series of site upgrades have been installed to mitigate for potential impacts related to the landfill including construction of a landfill cap, installation of a sea wall to prevent leachate migration and installation of methane collection trenches. Collectively these modifications have reduced the hazardous materials exposure risks to an acceptable level. However, future use of the site could result in potential exposure if not appropriately mitigated. Impact Haz-6: Exposure to Contaminated Soil, Soil Vapor, and Groundwater. As currently designed, utilities and foundation slabs shall be separated from landfill wastes by a minimum of 4 feet of clean material, however the potential for future maintenance work to penetrate into the subsurface where contamination remains cannot entirely be discounted. Soil and groundwater disturbance presents an exposure hazard to workers and trespassers. Disturbance of the subsurface also increases the potential for contamination to spread through surface water runoff, and through wind blown dust. These impacts are potentially significant. The potential for accidental release of and construction-worker exposure to existing hazardous materials during build-out under the OPSP is discussed separately under Impact Haz-2 above. Accidental release of existing hazardous materials following construction are discussed under Impact Haz-5. MitigationMeasures Haz-6a:Development and Implementation of Site Management Plans. A Site Management Plan shall be prepared that addresses the exposure risk to people and the environment resulting from future demolition, construction, occupancy, and maintenance activities on the property. The plans for the landfill portion of the OPSP shall be in accordance with RWQCB order No. 00-046, the PCMP and recommendations of the Environmental Consultant, and shall be reviewed and approved by the RWQCB, DTSC, the SMCEHD Groundwater Protection Program and the City of South San Francisco Public Works Department. Specific mitigation measures designed to protect human health and the environment shall be provided in the plan. At a minimum, the plan shall include the following: CHAPTER 11: HAZARDOUS MATERIALS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 11-17 1)Requirements for site specific Health and Safety Plans (HASP) shall be prepared in accordance with OSHA regulations by all contractors at the OPSP area. This includes a HASP for all demolition, grading and excavation on the site, as well as for future subsurface maintenance work. The HASP shall include appropriate training, any required personal protective equipment, and monitoring of contaminants to determine exposure. The HASP shall be reviewed and approved by a Certified Industrial Hygienist. The plan shall also designate provisions to limit worker entry and exposure and shall show locations and type of protective fencing to prevent public exposure to hazards during demolition, site grading, and construction activities. 2)Requirements for site-specific construction techniques that would minimize exposure to any subsurface contamination shall be developed. This shall include dewatering techniques to minimize direct exposure to groundwater during construction activities, treatment and disposal measures for any contaminated groundwater removed from excavations, trenches, and dewatering systems in accordance with local and Regional Water Quality Control Board guidelines. Groundwater encountered in excavations shall not be discharged into the neighboring storm drain, but into a closed containment facility, unless proven to have concentrations of contaminants below established regulatory guidelines. Extracted contaminated groundwater shall be required to be stored in tanks or other sealed container until tested. If testing determines that the water can be discharged into the sanitary sewer system, then the applicant shall acquire a ground water discharge permit from the City of South San Francisco Sanitary Sewer District and meet local discharge limits before being allowed to discharge into the sanitary sewer. Water shall be analyzed for the chemicals of concern at the site, including benzene, ethylbenzene, xylenes, chlorobenzene, naphthalene and additional compounds as requested by the receiving facility or the City of South San Francisco. 3)Waste relocation. Relocation or removal of existing landfill waste/refuse will be required for landfill cap upgrades and for site construction. Excavated waste can either be re-deposited on site or disposed of at an active landfill facility. Off-site disposal will require pre-characterization of the waste for acceptance at an approved waste disposal facility. Waste manifests will be prepared to document transportation and disposal. On-site disposal shall require proper placement, compaction, and capping of the refuse material. In either case, segregation of Class 2 and Class 3 from Class 1 material for disposal purposes shall be performed on-site to the extent possible. No Class 1 material shall be relocated or re-deposited on-site. BAAQMD Regulation 8 Rule 34 section 118 documents a limited exemption for construction activities at landfill sites. This section specifies that when the construction activities are related to “installing, expanding, replacing, or repairing components of the landfill gas, leachate, or gas condensate collection and removal systems.” Excavation for cap upgrades falls under this exemption. Excavation for construction purposes will also likely fall under this exemption. As such it will be necessary to provide BAAQMD with construction plans and other documentation as detailed under this regulation for the purposes of obtaining a letter of exemption from BAAQMD. Excavation procedures are also discussed in Measure Haz-2. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 11-18 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT 4)Future subsurface work plan. The plan shall document procedures for future subsurface landscaping work, utility maintenance, etc., with proper notification, where applicable. The plan shall include a general health and safety plan for each expected type of work, with appropriate personal protective equipment, where applicable. This plan may be included in the operations and maintenance plan as appropriate. Haz-6b: Landfill Gas System. Section 21160 of Title 27 of the CCR requires that closed landfills implement and maintain landfill gas control. A landfill gas (LFG) venting system shall be placed under the bottom slabs of each structure built entirely or partially over landfill material, to collect and vent the build up of gases diffusing through the landfill cap. The LFG system shall include spray- applied vapor barrier membranes, horizontal collection and passive venting, gas detection and monitoring. The system shall either have backup active collection and venting or shall be designed to facilitate retrofitting with an active system, if measures warrant the retrofit. Potential migration of LFG into the building space shall be mitigated by the collection and venting system, and secondly by the spray-applied membrane. Subsurface landfill gases shall be vented by a network of perforated piping placed beneath the building slabs. The exhaust gases shall be manifolded to a series of riser piping that is to be vented above structure roofs. Passive landfill gas systems do not require permits, however if an active system is installed, either at the time of construction or as part of a retrofit, a BAAQMD permit will be needed. Haz-6c: Non-use of Groundwater. Water supply wells shall not be installed at the site. This will prevent direct contact between the public and site groundwater and leachate. Haz-6d:San Mateo County Environmental Health Department Closure of Existing Facilities.Any businesses on the sitethat are currently registered in the hazardous materials business plan program shall submit a closure work plan in accordance with the SMCEHD Business Closure Policy prior to vacating the property. The closure plan shall detail any necessary sampling and remediation. Closure shall not be granted until businesses have demonstrated there is no need for further remediation, and shall include documentation of the removal of any hazardous chemicals. Implementation of mitigation measures Haz-6a through Haz-6d during disturbance of landfill materials, , which is anticipated to occur during the Phase I Project and may also occur during subsequent construction activities at the landfill site, such as buildout of the hotel site, would reduce the impact from exposure of construction and maintenance workers and the public to contaminated soils, groundwater and soil vapor to a level of less-than-significant. AIRPORT LAND USE PLAN Impact Haz-7 Airport Land Use Plan. The OPSP would be located within the jurisdiction of the Airport Land Use Plan for the San Francisco International Airport. According to the East of 101 area plan, the most stringent height limits in South San Francisco are south of Forbes Boulevard and Lindenville (the area between Railroad Avenue, South Spruce Avenue, and San Mateo Avenue), which is south CHAPTER 11: HAZARDOUS MATERIALS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 11-19 of the site. Federal Aviation Regulations, Part 77, limits building heights to an elevation of 161 feet above mean sea level, approximately 12 to 14 stories, in the most restricted areas, increasing at a slope of 20:1 to a height of 361 feet above mean sea level. Since the tallest building portion would not exceed 161 feet in height, the OPSP would be in compliance with the Airport Land Use Plan. The impact of the OPSP on the Airport Land Use Planis less-than-significant with no mitigation warranted. The OPSP area is not located within the vicinity of a private airstrip. Private aircraft are sometimes granted air space in the East of 101 area, but OPSP buildings and structures are expected to conform to design guidelines for visibility and meet aviation requirements. Therefore, the OPSP, including the Phase I Project, would have no impact relating to a private airstrip. ADOPTED EMERGENCY RESPONSE PLAN Although there will be some realignment of existing roads, no changes to the major access and evacuation routes are planned. Roads shall be designed to have adequate capacity for ingress/egress to the OPSP area. As the site is located at the shoreline, roads do not and will not exist which go through the site to other areas. Therefore, the OPSP would have no impact related to an adopted emergency response plan. WILDLAND FIRES The OPSP area is urbanized and is not in an area adjacent to wildland subject to wildfires. Therefore the OPSP, including the Phase I Project, would have no impact from wildland fires. CUMULATIVE HAZARDS AND HAZARDOUS MATERIALS IMPACTS Impact Haz-8: Cumulative Hazardous Impacts. The OPSP would be one of numerous sites, some of which are also existing hazardous materials sites that are anticipated to undergo development/redevelopment in the vicinity. The OPSP would contribute to a cumulative increase in the number of sites handling hazardous materials, and would result in a cumulative increase in transportation, use, disposal, and potential for exposure to and/or accidental release of hazardous materials during both construction and operations. However, the cumulative impact is expected to be slight and identified project-specific mitigation measures would reduce this impact to a less-than-significant level with no additional mitigation required. Potentially significant impacts of the OPSP are detailed above under the Impact Analysis section of this document. While build-out of the OPSP would incrementally increase the use and transport of hazardous materials as well as the potential for accidental release, implementation of the identified mitigation measures Haz-1b, Haz-1c, Haz-1d, Haz-1e, Haz-1f and Haz-5 would reduce the cumulative impact to less-than-significant.

September 14. SETTING CLIMATE AND TOPOGRAPHY The OPSP area is located in a relatively flat area east of Highway 101, immediately adjacent to the San Francisco Bay shoreline, in the City of South San Francisco. The regional climate is typical of the San Francisco Bay Area and is characterized by dry, mild summers and moist, cool winters. About 80 percent of the total annual precipitation occurs during the months of November through March with an average annual precipitation of 20.25 inches. Average daily temperatures range from a high of 73.4 degrees Fahrenheit in September to a low of 42.4 degrees Fahrenheit in January.1 The OPSP area consists of approximately 81 acres of land, consisting of the former Oyster Point landfill, which was a municipal waste facility operating from 1957 to 1970 and the Oyster Point Business Park. The surrounding area is largely developed with marina, research and development, light industrial, office, hotel, and open space uses. Portions of the site are hard-scaped with a mix of 1 Western Regional Climate Center, 2005. Weather Station: San Francisco WSO AP, California (047769). DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 12-2 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT asphalt parking and building structures. The unpaved portions of the former landfill are overlain by a low hydraulic conductivity landfill cap, which acts, in part, to restrict the flow of water into the waste material. A series of man-made structures provide for drainage of surface waters. The site slopes toward the bay, with the direction of slope varying across the site. The site elevation ranges from 0 to approximately 25 feet above Mean Sea Level (MSL). REGIONAL HYDROLOGY The majority of the OPSP area consists of fill material located east of the historic shoreline within the San Francisco Bay. As such, the site lacks natural surface drainages. A series of man-made structures provide drainage of surface waters. The largest watershed in the immediate vicinity is the Colma Creek watershed. The Colma Creek watershed includes portions of San Bruno Mountain as well as urbanized areas of Daly City, Colma, and South San Francisco. Most of this urbanized creek is channelized and/or conveyed underground to allow for urban development. The percent of impervious surface area in Colma Creek was previously estimated at 63 percent, the highest in the County.2 Colma Creek is a flood control channel maintained by the San Mateo County Department of Public Works that discharges into the San Francisco Bay just north of the San Francisco International Airport. In addition to the Colma Creek Watershed, a series of small watersheds are located along the shoreline in the vicinity of the site. GROUNDWATER The California Department of Water Resources (DWR) defines state groundwater basins based on geologic and hydrogeologic conditions. According to the DWR, the site is located within the Visitacion Valley Groundwater Basin. The Visitacion Valley Groundwater Basin consists of bedrock and unconsolidated sediments. Unconsolidated material in the Visitacion Valley Groundwater Basin has a relatively low storage capacity and minimal protection from potential surface contamination. Franciscan Complex bedrock underlies the water-bearing formations. Onsite there is a subsurface, low permeability, clayey formation of Bay Mud. The Bay Mud layer is overlain by waste material placed beyond the historic shoreline limits while the site was used as a landfill. The waste material is protected at the surface by a landfill cap. The landfill cap is discussed in more detail in the Hazards section of this document. The landfill cap includes a low hydraulic conductivity clay layer which acts to reduce infiltration of precipitation into the waste material, thus limiting the production of contaminated leachate. The Bay Mud layer and landfill cap confine the shallow groundwater. SITE HYDROLOGY As mentioned, the majority of the OPSP area is currently covered by low permeability surfaces. A network of surface drainage ditches is located on site along paved roads and parking lots. A drainage channel is located along the southern boundary of the OPSP area. Surface water is collected in six drainage pipes, four of which drain to the drainage channel and two which drain directly to the San Francisco Bay. FLOODING The majority of OPSP area is located outside of the 100-year flood hazard zone as delineated by the current Federal Emergency Management Agency (FEMA) Flood Insurance Rate Maps (FIRMs) (1981). The borders of the site which abut the bay waters are within the V-1 zone designation, which defines areas in the 100-year flood hazard zone with wave action. When mapped in 1981, a portion of 2 City of Daly City Stormwater Pollution Prevention Program, 1998 CHAPTER 12: HYDROLOGY OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 12-3 the northern, center of the site was also within the V-1 zone, however subsequent landfill closure activities included changes in site elevation. Therefore, this area would likely no longer be within this zone but cannot be confirmed due to the age of the available FEMA FIRMS. FERM has updated information related to fill areas near the site, but not within the OPSP area (2001). REGULATORY SETTING The proposed OPSP must be constructed in accordance with several regulatory programs, laws, and regulations that aim to protect surface water resources. In some cases, Federal laws are administered and enforced by state and local government. In other cases, state and local regulations in California are stricter than those imposed by Federal law. This section summarizes relevant regulatory programs, laws, and regulations with respect to hydrology and water quality and how they relate to the proposed OPSP. FEDERAL LAWS AND REGULATIONS Clean Water Act The Clean Water Act (CWA) was enacted by Congress in 1972 and amended several times since inception. It is the primary federal law regulating water quality in the United States, and forms the basis for several state and local laws throughout the country. Its objective is to reduce or eliminate water pollution in the nation’s rivers, streams, lakes, and coastal waters. The CWA prescribed the basic federal laws for regulating discharges of pollutants as well as set minimum water quality standards for all waters of the United States. Several mechanisms are employed to control domestic, industrial, and agricultural pollution under the CWA. At the Federal level, the CWA is administered by the U.S. Environmental Protection Agency (EPA). At the state and regional level, the CWA is administered and enforced by the State Water Resources Control Board (SWRCB) and the Regional Water Quality Control Boards (RWQCBs). The State of California has developed a number of water quality laws, rules, and regulations, in part to assist in the implementation of the CWA and related federally mandated water quality requirements. In many cases, the Federal requirements set minimum standards and policies and the laws, rules, and regulations adopted by the State and Regional Boards exceed the Federal requirements. STATE LAWS AND REGULATIONS Porter-Cologne Water Quality Control Act The Porter-Cologne Water Quality Control Act establishes the SWRCB and the RWQCBs as the principal state agencies having primary responsibility for coordinating and controlling water quality in California. The Porter-Cologne Act establishes the responsibility of the RWQCBs for adopting, implementing, and enforcing water quality control plans (Basin Plans), which set forth the state’s water quality standards (i.e. beneficial uses of surface waters and groundwater) and the objectives or criteria necessary to protect those beneficial uses. The NPDES permit (see subsequent section) must be consistent with the Basin Plan for the site region. NPDES Permit Requirements The CWA has nationally regulated the discharge of pollutants to the waters of the U.S. from any point source since 1972. In 1987, amendments to the CWA added section 402(p), which established a framework for regulating nonpoint source (NPS) storm water discharges under the National Pollutant DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 12-4 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Elimination System (NPDES). The Phase I NPDES storm water program regulates storm water discharges from industrial facilities, large and medium-sized municipal separate storm sewer systems (those serving more than 100,000 persons), and construction sites that disturb five or more acres of land. Under the program, the applicant shall be required to comply with NPDES permit requirements. The NPDES General Construction Permit Requirements apply to clearing, grading, and disturbances to the ground such as excavation. The applicant is required to submit a Notice of Intent (NOI) with the State Water Resource Control Board’s (SWRCB) Division of Water Quality. The NOI includes general information on the types of construction activities that will occur on the site. The applicant shall also be required to submit a site-specific plan called the Stormwater Pollution Prevention Plan (SWPPP) for construction activities. The SWPPP shall include a description of Best Management Practices (BMPs) to minimize the discharge of pollutants from the site during construction. It is the responsibility of the property owner to obtain coverage under the permit prior to site construction. The NPDES General Industrial Permit Requirements apply to the discharge of storm water associated with industrial sites. It is assumed that the future R&D labs would require compliance with the requirements because it is likely that the Standard Industrial Code for the R&D labs would be 2834 (Pharmaceutical Preparations). The permit requires the implementation of management measures that will achieve the performance standard of best available technology (BAT) economically achievable and best conventional pollutant control technology (BCT). Under the statute, operators of new facilities must implement industrial BMPs in the Plan SWPPP and perform monitoring of storm water discharges and unauthorized non-storm water discharges. An annual report must be submitted to the RWQCB each July 1. Operators of new facilities must file an NOI at least 14 days prior to the beginning of operations. Sea Level Rise and Executive Order S-13-08 In November 2008, Governor Arnold Schwarzenegger issued Executive Order S-13-08. The order indicates that future potential sea level rise associated with climate change may have a substantial effect on coastal development, and provided for the formation of an independent panel to complete a California Sea Level Rise Assessment Report by December 1, 2010. This panel, the California Adaptation Advisory Panel to the State of California, published the required report in November 2010 titled Preparing for the Effects of Climate Change – A Strategy for California.3 This study notes that the State has requested an assessment of defensible sea level rise projections for the West Coast from the National Research Council, but that this study has not yet been completed. In the interim, BCDC has proposed Bay Plan amendment language, which includes guidance for addressing future sea level rise scenarios associated with planning and permitting development in potentially susceptible areas in the San Francisco Bay Area. These scenarios are: • a sea level rise of 16 inches by 2050; and • a sea level rise of 55 inches by 2100. These values represent the upper end of the range of sea level rise estimates and are consistent with preliminary state recommendations for 100-year sea level rise. These values are meant to ensure that projects take these potentially high estimates into account when planning infrastructure and development projects, prior to the release of official sea level rise projections. 3 California Adaptation Advisory Panel to the State of California, prepared by Pacific Council, Preparing for the Effects of Climate Change – A Strategy for California, November 2010. CHAPTER 12: HYDROLOGY OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 12-5 LOCAL PROGRAMS AND REGULATIONS San Mateo Countywide Stormwater Pollution Prevention Program To comply with the Clean Water Act, San Mateo County and the 20 cities and towns in the County formed the San Mateo Countywide Stormwater Pollution Prevention Program (STOPPP). STOPPP holds a joint municipal NPDES permit from the San Francisco Bay RWQCB. The permit includes a comprehensive plan to reduce the discharge of pollutants to creeks, San Francisco Bay, and the ocean to the maximum extent possible. San Francisco Bay Water Quality Control Plan (Basin Plan) The San Francisco Bay RWQCB is responsible for the development, adoption, and implementation of the Water Quality Control Plan for the San Francisco Bay region. The Basin Plan is the master policy document that contains descriptions of the legal, technical, and programmatic bases of water quality regulation in the San Francisco Bay Region. The Basin Plan identifies beneficial uses of surface waters and groundwater within its region and specifies water quality objectives to maintain the continued beneficial uses of these waters. Projects under the proposed OPSP are required to adhere to all water quality objectives identified in the Basin Plan. Beneficial Uses of Surface Waters and Groundwaters The Basin Plan defines beneficial uses for surface waters and groundwater in its corresponding jurisdiction. The beneficial uses of groundwater in the Visitacion Valley Groundwater Basin include municipal and domestic supply, industrial process supply, industrial supply, and agricultural supply. East of 101 Area Plan The East of 101 area plan provides detailed planning policies that are consistent with policies of the adopted South San Francisco General Plan. With respect to hydrology and water quality, the plan aims to reduce flooding by evaluating specific development proposals to determine drainage and flood protection requirements, and to prevent the degradation of water quality by minimizing erosion and sedimentation, and requiring that projects under the proposed OPSP comply with NPDES permit requirements.4 City of South San Francisco The City of South San Francisco Water Quality Control Plant requires Source Control Measures of Stormwater Pollutants to comply with their NPDES permit, including methods for managing pollution sources. Applicable control measures include utilization of stormwater pollution prevention devices, management of refuse areas, management of pesticide/fertilizer application for landscaping, use of treatment devices for interior level parking garage floor drains, and marking of on-site storm drains.5 4 City of South San Francisco, East of 101 Area Plan, 1994. 5 South San Francisco Water Quality Control Plant, July 2005 DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 12-6 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT IMPACTS AND MITIGATION MEASURES STANDARDS OF SIGNIFICANCE The following thresholds for measuring hydrology impacts are based upon CEQA Guidelines thresholds: 1. Would the project violate any water quality standards or waste discharge requirements? 2. Would the project substantially deplete groundwater supplies or interfere substantially with groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table level (e.g., the production rate of pre-existing nearby wells would drop to a level which would not support existing land uses or planned uses for which permits have been granted)? 3. Would the project substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, in a manner which would result in substantial erosion or siltation on- or off-site? 4. Would the project substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, or substantially increase the rate or amount of surface runoff in a manner, which would result in flooding on- or off-site? 5. Would the project create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff? 6. Would the project otherwise substantially degrade water quality? 7. Would the project place housing within a 100-year flood hazard area as mapped on a federal Flood Hazard Boundary or Flood Insurance Rate Map or other flood hazard delineation map? 8. Would the project place within a 100-year flood hazard area structures, which would impede or redirect flood flows? 9. Would the project expose people or structures to a significant risk of loss, injury or death involving flooding, including flooding as a result of climate-induced sea level rise or the failure of a levee or dam? 10. Would the project cause inundation by seiche, tsunami, or mudflow? WATER QUALITY STANDARDS OR WASTE DISCHARGE REQUIREMENTS Potential sources of pollutants include groundwater that is in contact with landfill waste material (leachate) and traditional non-point source pollutants. Non-point source pollutants (NPS) are washed by rainwater from roofs, landscape areas, and streets and parking areas into the drainage network. Typical industrial NPS pollutants for various industrial activities are listed in Table 12.1 below. CHAPTER 12: HYDROLOGY OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 12-7 Parking and research uses at the site may generate some of these classes of pollutants. Impact Hydro-1: Potential Contamination of Off-Site Waters due to Leachate Migration. The OPSP area is located within the historical limits of the Bay. Subsurface water at the site is underlain by Bay Mud and has a low-hydraulic conductivity cap, which confines the groundwater. Based on ongoing monitoring at the site, leachate, which has elevated contaminant concentrations from the landfill material, is not migrating off-site. Re-development of the site shall require excavation of a portion of the landfill cap, and shall require deep foundation piers which may penetrate the Bay Mud. The potential for off-site migration of leachate as a result of modification the landfill cap and underlying Bay Mud represents a potentially significant impact. Mitigation Measure Hydro-1: Best Management Practices (BMPs) shall be used during installation of foundation piers to reduce the potential for gaps in the subsurface confining TABLE 12.1 POTENTIAL POLLUTANTS FROM INDUSTRIAL ACTIVITIES INDUSTRIAL ACTIVITY Se d i m e n t s Nu t r i e n t s Me t a l s Or g a n i c s a n d T o x i c a n t s Fl o a t a b l e M a t e r i a l s Ox y g e n - D e m a n d i n g Su b s t a n c e s Oi l & G r e a s e Ba c t e r i a Pe s t i c i d e s Vehicle & Equipment Fueling X X X Vehicle & Equipment Washing X X X X X X Vehicle & Equipment Maintenance & Repair X X X Outdoor Loading & Unloading of Materials X X X X X X X Outdoor Container Storage of Liquids X X X X X X Outdoor Process Equipment Operations & Maintenance X X X X Outdoor Storage of Raw Materials, Products, & Byproducts X X X X X X X Waste Handling & Disposal X X X X X X Contaminated or Erodible Surface Areas X X X X X X X X Building & Grounds Maintenance X X X X X X X Building Repair, Remodeling, & Construction X X X X Parking/Storage Area Maintenance X X X X Source: California Stormwater Quality Association, 2003. California Stormwater BMP Handbook, Industrial & Commercial. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 12-8 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT layers around the piers. BMP requirements shall be identified in the SWPPP and shall be developed by the applicant or their authorized representative. The exact BMPs to be implemented shall depend on final pier design and type, but can include pre-drilling and grouting of concrete piers, use of hollow steel piers, or other methods to reduce the risk of displaced refuse creating a void in the Bay Mud layer. The proposed BMPs shall be benchmarked against the California Department of Transportation Stormwater Quality Handbooks Construction Site Best Management Practices (BMPs) Manual (2003 and associated updates). Mitigation Measure Haz-4a: Landfill Cap Upgrades would also reduce impact Hydro-1 through repair and upgrade of the cap which will act to minimize generation of leachate. Mitigation Measure Haz-4d and 4e: Monitoring for Leachate Migration and Operation and Maintenance Activities would also reduce impact Hydro-1 through requirements for post-construction monitoring for leachate migration, with repairs to prevent migration completed on an as needed basis. Implementation of these mitigation measures Hydro-1, Haz-4a, Haz-4d and Haz-4e would reduce the OPSP’s impact related to contamination of off-site waters to a level of less-than-significant through use of BMPs during installation of foundation piers, landfill cap upgrades, and continued monitoring for leachate migration during operation and maintenance. Impact Hydro-2: Potential Construction and Post-construction Contamination of Bay Waters:Construction activities at the site will create temporary and long term alterations of the site terrain, creating potential erosion concerns.The migration of laboratory and parking lot pollutants into the bay could potentially impair water quality. This represents a potentially significant impact. Mitigation Measure Hydro-2: Preparation and Implementation of Project SWPPP. Pursuant to NPDES requirements, the applicant of a project under the OPSP shall develop a SWPPP to protect water quality during construction. If the SWPP will be developed after September 2, 2011, the SWPPP shall be developed by a California Qualified SWPPP Developer in accordance with the State Water Resources Control Board Construction General Permit 2009-009-DWQ. The project SWPPP shall include, but is not limited, to the following mitigation measures for the construction period: 1) Grading and earthwork shall be allowed with the appropriate SWPPP measures during the wet season (October 1 through April 30) and such work shall be stopped before pending storm events. 2) Erosion control/soil stabilization techniques such as straw mulching, erosion control blankets, erosion control matting, and hydro-seeding, shall be utilized in accordance with the regulations outlined in the Association of Bay Area Governments “Erosion & Sediment Control Measures” manual. Silt fences shall be installed down slope of all graded slopes. Hay bales shall be installed in the flow path of graded areas receiving concentrated flows and around storm drain inlets. CHAPTER 12: HYDROLOGY OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 12-9 3) BMPs to be developed by the applicant shall be used for preventing the discharge or other construction-related NPDES pollutants beside sediment (i.e. paint, concrete, etc) to downstream waters. 4) After construction is completed, all drainage facilities shall be inspected for accumulated sediment and these drainage structures shall be cleared of debris and sediment. In accordance with the handbook C.3 Stormwater Technical Guidance, Version 2, permanent mitigation measures for stormwater shall be submitted as part of project application submittals with the Planning Permit Application and the Building Permit Application. Elements that shall be addressed in the submittals include the following: 5) Description of potential sources of erosion and sediment at the OPSP area. R&D activities and significant materials and chemicals that could be used at the proposed OPSP area shall be described. This shall include a thorough assessment of existing and potential pollutant sources. 6) Identification of BMPs to be implemented at the OPSP area based on identified industrial activities and potential pollutant sources. Emphasis shall be placed on source control BMPs, with treatment controls used as needed. 7) Development of a monitoring and implementation plan. Maintenance requirements and frequency shall be carefully described including vector control, clearing of clogged or obstructed inlet or outlet structures, vegetation/landscape maintenance, replacement of media filters, etc. 8) The monitoring and maintenance program shall be conducted as described in Haz-4e. 9) Proposed pervious and impervious surfaces, including site design measures to minimize impervious surfaces and promote infiltration (except where the landfill cover is present). 10) Proposed locations and approximate sizes of stormwater treatment measures. Preparation and implementation of a SWPPP at the OPSP area and implementation of the permanent mitigation measures following completion of site construction, as included in mitigation measure Hydro-2, would reduce impacts on potential contamination of local groundwater to a level of less- than-significant. GROUNDWATER DEPLETION/ RECHARGE The proposed OPSP shall not directly draw on, or otherwise reduce groundwater resources. (See Chapter 17: Utilities for a further discussion of water supply through CalWater.) The site is located within the historic limits of the Bay. Precipitation at the site shall be directed into the subsurface or into a water conveyance structure which shall direct water to the Bay. Although redevelopment of the site would result in an increase in the total amount of hard-scaping at the site (impervious surface areas), given the nature of the site, this will not affect the recharge of a useable groundwater basin. Thus, the proposed OPSP would not likely have a negative effect on groundwater recharge. No impact would occur and no mitigation is required. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 12-10 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT INCREASED EROSION OR SILTATION TO RECEIVING WATERS The proposed OPSP is not subject to the hydromodification management measures of the Lead Agency’s National Pollution Discharge Elimination System (NPDES) Permit.6 This exclusion is attributed to the OPSP area’s location in an identified ‘Low Gradient Area.’ In addition, the OPSP area’s stormwater is discharged directly to the Bay via hardened channels. Changes in the timing and volume of runoff from a site are known as “hydrograph modification” or “hydromodification”. When a site is developed, much of the rainwater can no longer infiltrate into the soil, so it flows offsite at faster rates and greater volumes. As a result, erosive levels of flow occur more frequently and for longer periods of time in creeks and channels downstream of the OPSP. As indicated above, the proposed OPSP shall be designed to minimize the potential for an increase in leachate (water percolating through waste material within the former landfill). Water shall be directed to into concrete lined drainage structures. Existing drainage structures divert water into the sub- surface and directly into bay waters. Additional drainage structures, if needed, shall direct precipitation into bay waters. Site waters shall not enter natural creeks or other earthen channels, and shall move directly from the site to the bay. The Post Closure Monitoring Plan (Gabewell, 2000) for the site also required a minimum 2 foot erosion resistant layer for all non-paved areas. These areas shall also be landscaped to further protect the surface from erosion. This requirement is also discussed in the “Hazardous Materials” section of this document. Despite the low erosion potential of the OPSP, portions of the OPSP area will consist of bare earth susceptible to rainfall during construction. In the event of rainfall, silt could be transported to the San Francisco Bay via overland transport. Impact Hydro-3: Erosion or Siltation On- or Off-Site. Construction of the proposed OPSP would involve demolition of existing structural foundations and will involve excavation of both landfill waste material and the earthen cap overlying the waste. Construction operations associated with the OPSP would present a threat of soil erosion from soil disturbance by subjecting unprotected bare soil areas to the erosional forces of runoff during construction activities. This represents a potentially significant impact. Mitigation Measure Hydro-3:Compliance with NPDES Requirements. Applicants for a project under the OPSP shall comply with all Phase I NPDES General Construction Activities permit requirements established by the CWA and the Grading Permit requirements of the City of South San Francisco. Erosion control measures to be implemented during construction shall be included in the project SWPPP. The project SWPPP shall accompany the NOI filing and shall outline erosion control and storm water quality management measures to be implemented during and following construction. The SWPPP shall also provide the schedule for monitoring performance. Refer to Mitigation Measure Hydro-2 for more information regarding the project SWPPP. Implementation of Phase I NPDES General Construction Activities permit requirements would reduce construction-related impacts associated with erosion and/or siltation to less- than-significant. 6 Appendix J, C.3Stormwater Technical Guidance Manual, San Mateo Countywide Water Pollution Prevention Program. CHAPTER 12: HYDROLOGY OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 12-11 CHANGES IN STORMWATER RUNOFF The OPSP area currently has a high ratio of impervious surfaces, including both hardscaping and the low hydraulic conductivity layer of the landfill cap. Redevelopment of the site will result in changes in the route of water flow on site, primarily based on diversion of precipitation from roofs directly into concrete lined drainage channels, however the net runoff from the site is expected to be similar prior to and following re-development. In addition, water from the site is transported directly from the site to the bay through over-land sheet flow or through the drainage system. Water does not enter downstream infrastructure. No impact associated with increases in peak runoff is anticipated and no mitigation is necessary. The OPSP will have no impact on stormwater drainage system, and no mitigation is required. As part of the stormwater information to be included with application submittals with the Planning Permit Application and the Building Permit Application, the project applicant shall submit hydraulic computations to establish no increased run off from the site. In the event that post development flows are higher than pre-development flows, the project applicant shall mitigate the excess run off from the site. OTHERWISE SUBSTANTIALLY DEGRADE WATER QUALITY The proposed OPSP will not alter the amount of surface area contributing non-point source pollution runoff. Other previously mentioned impacts, if mitigated, would ameliorate potential short and long term negative impacts on water quality. Therefore, there will be no additional significant impact on water quality. STRUCTURES WITHIN A 100-YEAR FLOOD HAZARD AREA The OPSP does not include housing and the majority of the OPSP area is located outside of the 100- year flood hazard zone as delineated by the current Federal Emergency Management Agency (FEMA) Flood Insurance Rate Maps (FIRMs). The OPSP will have no impact related to housing and flooding. The OPSP area will not place new structures within the 100-year flood hazard zone as delineated by the current Federal Emergency Management Agency (FEMA) Flood Insurance Rate Maps (FIRMs). In regard to impeding flood or any other flows, the OPSP will have no impact. SIGNIFICANT RISK INVOLVING FLOODING Impact Hydro-4: Risk of Flooding. The OPSP is not located within the vicinity of a levee, nor in a potential flood path of a dam failure. The OPSP is located on the coast of the San Francisco Bay and therefore could potentially be at risk of flooding due to climate-induced sea level rise. However, grading changes proposed as a part of the Phase I Project would reduce the potential of flooding to a less-than- significant impact. As discussed in the regulatory section above, the recommended sea level rise assumptions of 16 inches by 2050 and 55 inches by 2100 have been used to assess the potential for climate-induced sea level rise flooding at the OPSP site. Figure 12.1 shows the potential for flooding under these assumed future conditions with no changes to the OPSP site. This figure indicates that substantial portions of the Marina area would be susceptible to flooding under the year 2100 sea level rise scenario. The Phase I Project proposes landfill waste relocation and re-grading of the Marina area according to an approved grading plan. The proposed re-grading will result in higher elevation of areas near the shoreline, with the resultant reduced potential for flooding under assumed future climate-change induced sea level rise conditions shown in Figure 12.2.

The impact related to risk of loss, injury or death involving flooding, including flooding as a result of climate-induced sea level rise would be less than significant. INUNDATION BY SEICHE, TSUNAMI OR MUDFLOW A seiche is a tide-like rise and drop of the surface of a landlocked body of water (e.g., a lake); its period can vary from a few minutes to several hours. The site is not in close proximity to a landlocked body of water that could cause inundation by seiche. The site is also nearly level and not bordered by hills which could result in mudflow across the site. Consequently, there would be no impact related to seich or mudflow. Impact Hydro-5: Inundation by Tsunami. Tsunamis, or tidal waves, are huge sea waves that are caused by seismic activity or other disturbance of the ocean floor. Portions of South San Francisco that are near the bay and low-lying are considered to be at risk for inundation by tsunami wave run-up. Wave run up is estimated at 6 feet above mean sea level for a 500-year tsunami.7 The margins of the OPSP area immediately border the bay waters. As such, a fringe of area is at or below 6 feet above mean sea level. However, development plans to not include development of the margins of the site that are at or below 6 feet above mean sea level. In addition, much of the shoreline of the OPSP area is protected by rip-rap to prevent damage to the shoreline by wave run-up. Consequently, this impact would be less-than-significant with no mitigation required. CUMULATIVE HYDROLOGY IMPACT ANALYSIS Impact Hydro-6: Cumulative Impacts on Hydrology and Water Quality. The increased construction activity and new development resulting from the OPSP, in conjunction with other foreseeable development in the city, would result in less-than-significant impacts on hydrology and water quality conditions with no additional mitigation measures necessary. Assuming concurrent implementation of the OPSP with other reasonably foreseeable future projects in the vicinity, adverse cumulative effects on hydrology and water quality could include construction impacts related to increases in stormwater runoff and pollutant loading to San Francisco Bay. The OPSP and other future projects in the city would be required to comply with drainage and grading ordinances intended to control runoff and regulate water quality at each development site. New projects would be required to demonstrate that stormwater volumes could be managed by downstream conveyance facilities and would not induce flooding. Therefore, the effect of the OPSP on water quality and hydrology, in combination with other foreseeable projects, would be less-than- significant. 7 City of South San Francisco, prepared by Dyett and Bhatia, South San Francisco General Plan: Health and Safety Element, 1999, p. 250. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 12-16 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT This page intentionally left blank. OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 13-1 13 LAND USE INTRODUCTION This chapter describes existing land uses, adopted General Plan land use classifications, and zoning designations on and around the OPSP. This chapter also describes the applicable plans and policies that guide development in the OPSP area and evaluates the OPSP’s consistency with these plans and policies and other existing land use regulations. SETTING HISTORY South San Francisco has a distinctive land use pattern that reflects the decision to initially locate industrial areas east of supporting homes and businesses in order to take advantage of topography and winds on Point San Bruno.1 Another development trend that shaped the arrangement of uses was the extensive residential development that occurred during the 1940s and 1950s, creating large areas almost entirely developed with single-family housing. As a result, South San Francisco is largely comprised of single-use areas, with industry in the eastern and southeastern portions of the City, single family homes to the north and west, commercial uses along a few transportation corridors, and multiple family housing clustered in those same corridors and on hillsides. During the 1950s, the City of South San Francisco converted previously unused marshlands into areas usable for industrial development, drastically reshaping the shoreline and attracting light industry to the City for the first time. Plans were announced in 1963 for a 600-acre industrial park adjacent to the newly developed Oyster Point Marina. This industrial park was South San Francisco’s first industrial development to incorporate comprehensive planning and integrated design and performance provisions. It supplied ample parking and consistent landscaping and building design. In some ways a microcosm of American industry, South San Francisco has been making an industrial transformation for the past 30 years. Steel production and other heavy industries have largely been replaced by warehousing, research, development and biotechnology. Because the City’s industrial base has continued to evolve as the context for industry has changed, industry will continue to play an important role in South San Francisco’s future. The City’s continued status as a goods transportation hub, stemming mainly from proximity to San Francisco International Airport, is reflected in the presence of large tracts of land, formerly used for heavy industry, east of U.S. 101. As high technology businesses have moved into many of these older industrial areas, conflicts, such as between automobile and truck traffic, and land use and visual 1 City of South San Francisco, prepared by Dyett and Bhatia, South San Francisco General Plan, 1999. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 13-2 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT character have become increasingly pronounced. The needs of business centers include smaller blocks, more through street connections, ancillary facilities such as restaurants, easier connections to transit, sidewalks and bikeways and higher landscape standards. These needs are much different than those of warehousing and industrial areas. The City attempts to balance regional growth objectives with conservation of residential and industrial neighborhoods. EXISTING USES The OPSP is located in the East of 101 area, which is largely comprised of industrial and high technology business uses. As with the proposed OPSP, many other sites in the area have already or have plans to increase the intensity of research and development uses in this area. The Oyster Point Business Park encompasses the northern portion of the OPSP area. It is a privately owned series of five single-story buildings currently occupied by a variety of light industrial, office, and R&D tenants (see Figure 3.2). The Oyster Point Marina fills the remainder of the OPSP area. This area was a landfill closed in the 1970s and is owned by the City of South San Francisco and managed through a Joint Powers Agreement with the San Mateo County Harbor District. Currently, this area hosts a variety of uses including a dry boat storage area, a marine support services building, two small office buildings, a small inn and banquet hall, a bait and tackle shop, a boat and motor mart and a yacht club. The remaining area is vacant or serves as parking for the docks, boat ramp, and the Bay Trail at the Oyster Point Marina (see Figure 3.2). The Oyster Cove Marina is located to the west of the Oyster Point Business Park and the Oyster Point Marina is located on the north side of the Point. A ferry terminal with connections to Oakland is approved and is being constructed in the Oyster Point Marina as a separate project – service is set to begin in 2011. REGULATORY SETTING There are no federal regulations applicable to the proposed OPSP. San Francisco Bay Conservation and Development Commissions (BCDC) and the San Francisco Bay Plan As required by the McAteer-Petris Act, the San Francisco Bay Plan was submitted to the Legislature and the Governor of California in 1969. During the legislative session that year, revisions were enacted into the McAteer-Petris Act designating the San Francisco Bay Conservation and Development Commission (BCDC) as the permanent agency responsible for carrying out the Bay Plan. The 1969 revisions to the Act further specified the area and scope of the Commission's authority and established the permit system for the regulation of the Bay and shoreline. In addition to the controls over filling and dredging in the Bay, BCDC has limited control over the Bay shoreline as specified in the McAteer-Petris Act. Such limited shoreline jurisdiction is necessary to reduce pressures for Bay filling that would result from poor use of available shoreline land, and to assure that public access to the Bay is provided wherever feasible. BCDC's shoreline jurisdiction, as defined in the McAteer-Petris Act, consists of the area between the Bay shoreline, as defined in the Act, and a line 100 feet landward of and parallel to the shoreline. The Act further specifies that certain water-oriented land uses should be permitted on the shoreline, including ports, water-related industries, airports, wildlife refuges, water-oriented recreation and public assembly, desalinization plants, and CHAPTER 13: LAND USE OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 13-3 power plants requiring large amounts of water for cooling purposes. Priority use areas designated for such uses in the Bay Plan are to be reserved for them in order to minimize the need for future filling in the Bay for such uses. Within the 100-foot shoreline jurisdiction but outside of the areas designated for priority uses, BCDC may deny an application for a permit for a proposed project only on the grounds that the project fails to provide maximum feasible public access, consistent with the proposed project, to the Bay and the shoreline. These other shoreline areas should be used in any manner that would not adversely affect enjoyment of the Bay and shoreline by residents, employees, and visitors within the area itself or within adjacent areas of the Bay and shoreline. Any public agency or private owner holding shoreline lands is required to obtain a permit from BCDC before proceeding with development. Permits may be granted or denied only after public hearings (except for emergency or minor repairs or minor improvements which may be granted by the Executive Director) and after the process for review and comment by the city or county has been completed. The shoreline along the OPSP area is designated as a Waterfront Park Priority Use area, with the following description: Oyster Point Marina Park - Preserve and improve marina and shoreline park. Preserve picnicking, swimming, boating, hiking, windsurfing, and fishing opportunities. Possible ferry terminal. Allow if compatible with park and marina use; serve with bus public transit to reduce traffic and parking needs. Some fill may be needed. Provide signage regarding fish consumption advisories for anglers. South San Francisco General Plan The City of South San Francisco General Plan (1999 as amended in 2010) provides long-term guidance and policies for maintaining and improving the quality of life in, and the resources of, the community, both man-made and natural. The General Plan provides direction for the City’s growth and development. The site’s General Plan designation is Park and Recreation along the Bay edge, Business Commercial to the west and north of the existing Oyster Point Boulevard and Costal Commercial on the remainder of the area. The base floor area ratio (FAR) for Business Commercial is 0.5, but can be increased to 1.0 with structured parking or above that amount with transportation demand management plans as allowed by municipal code section 20.110.003(C). As part of OPSP approvals, a General Plan amendment would be adopted. The Business Commercial designation would be expanded to include all the proposed office/R&D buildings, with Coastal Commercial filling the remaining non-Park and Recreation area. Additionally, the text of the General Plan would be modified to reflect the higher intensity of planned development in this area. An FAR of 1.25 for the Business Commercial area is proposed, 2.0 for the hotel area and 1.0 for the remainder of the Coastal Commercial area and to clarify the City’s policy that office/R&D uses are permitted in the Coastal Commercial and Business Commercial areas. East of 101 Area Plan The OPSP site is part of the “East of 101” Planning Sub-Area as defined by the City of South San Francisco General Plan. The East of 101 area plan, adopted in 1994, was prepared to maximize the potential of undeveloped or underused properties in the City’s traditional industrial East of 101 area. Upgrading of existing uses and provisions for quality design are important components of the OPSP. In addition to policies relating to land use dispersion, intensities, and transportation, the OPSP includes a Design Element to help achieve high-standard development. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 13-4 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT South San Francisco Municipal Code and the Oyster Point Marina Specific Plan District Policies set forth in the General Plan and East of 101 area plan are implemented through enforcement of the City’s zoning regulations as presented in the City of South San Francisco Municipal Code (SSFMC). Zoning regulations prescribe the allowable uses within specific zoning districts and impose standards on those uses. The area to the west and north of the existing Oyster Point Boulevard is zoned B-C (Business Commercial) under the City’s existing zoning regulations. The remainder of the OPSP area makes up the Oyster Point Marina Specific Plan District, which is subject to the provisions of the SSFMC Chapter 20.230 (Oyster Point Marina Specific Plan District) as proposed for amendment. As part of OPSP approvals, a Specific Plan amendment would be adopted, changing the name of the district to the “Oyster Point Specific Plan District” (dropping the “Marina”) and incorporating the entire OPSP area. The municipal code would be revised to be consistent with the development planned under the proposed OPSP. CONSISTENCY DISCUSSION The proposed OPSP and Phase I Project development is consistent with the following applicable General Plan policies: Land Use Policy 2-G-2 Maintain a balanced land use program that provides opportunities for continued economic growth, and building intensities that reflect South San Francisco’s prominent inner bay location and excellent regional access. The proposed OPSP would result in higher density office/R&D uses to take advantage of the opportunities of this Bay-side site and upcoming ferry service as well as other uses such as a hotel, recreation, and supporting retail/restaurant/commercial uses. Policy 2-G-3 Provide land use designations that maximize benefits of increased accessibility that will result from BART extension to the city and adjacent locations. The proposed OPSP would provide a large employment center near the soon to be complete ferry terminal and would be expected to link into the existing BART and Caltrain commute via bicycle, SamTrans busses and/or shuttles. East of 101 Area Policy 3.5-G-1 Provide appropriate settings for a diverse range of non-residential uses. The proposed OPSP would result in office/R&D uses as well as other uses such as a hotel, recreation/open space, supporting retail/restaurant/commercial uses, and retention of the marinas. New residential uses are not proposed. Policy 3.5-G-3 Promote campus style biotechnology, high technology and research and development uses. CHAPTER 13: LAND USE OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 13-5 The proposed OPSP includes higher density office/R&D uses in a campus-like setting including open space, structured parking and plazas shared among buildings. Policy 3.5-I-3 Do not permit any residential uses in the East of 101 area. The OPSP does not propose new residential uses in the OPSP area. Existing live-aboard boats in the marina would continue to be permitted. Policy 3.5-I-4 Unless otherwise stipulated in a specific plan, allow building heights in the East of 101 area to the maximum limits permissible under Federal Aviation Regulations Part 77. The OPSP will default to allowable building heights under Federal Aviation Regulations Part 77. Policy 3.5-I-5 Do not vary permitted maximum development intensities based on lot-size. Per the proposed Oyster Point Specific Plan District, the Floor Area Ratio for the office/R&D uses in the OPSP area would be determined across the entire planning area in aggregate, rather than on a lot-by-lot basis. Policy 3.5-I-8 Encourage the development of employee-serving amenities with restaurants, cafes, support commercial establishments such as dry- cleaners, to meet the needs of the employees in the East of 101 area. Such uses could be located in independent centers or integrated into office parks or technology campuses. The OPSP proposes 10,000 square feet of auxiliary commercial in Phase I, approximately 40,000 square feet of retail/restaurant/commercial with the hotel use, and could support additional commercial as an allowed auxiliary use when subsequent phases of the office/R&D are built out. Policy 3.5-I-10 Prepare a new Concept Plan for the Oyster Point area. Work with the Bay Conservation and Development Commission (BCDC) to reconcile the differing designations for the area in the City’s General Plan and BCDC’s park priority use in the San Francisco Bay Plan. The Applicant proposes a new Oyster Point Specific Plan. Development in the OPSP area will require coordination with and permitting from BCDC, consistent with the proposed OPSP and BCDC regulations. In 1999, the City worked with BCDC to amend the Bay Plan to allow for a wider range of uses in and around the Oyster Point Marina area. Policy 3.5-I-11 Do not permit any new warehousing and distribution north of East Grand Avenue or in areas designated Business Commercial. The proposed OPSP does not include any warehousing or distribution uses; in fact, the proposed OPSP includes the framework to transition away from warehousing uses toward uses that are more compatible with the Business Commercial land use designation. Policy 3.5-I-13 Facilitate waterfront enhancement and accessibility by: DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 13-6 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Establishment of uses that would bring people to the waterfront (see polices 3.5-I-8 and 3.5-I-9); Establishment of a Bayshore design review area as part of the Zoning Ordinance; and Ensuring that the Park Recreation and Open Space Master Plan include specific improvements for shoreline enhancement and accessibility, as spelled out in the East of 101 Area Plan. In the OPSP area, office/R&D uses and open space will attract employees to the waterfront, the hotel will attract visitors, and the open space, park and Bay Trail uses will attract residents and enhance the shoreline. Transportation Policy 4.2-G-5 Make efficient use of existing transportation facilities and, through the arrangement of land uses, improved alternate modes, and enhanced integration of various transportation systems serving South San Francisco, strive to reduce the total vehicle-miles traveled. A ferry terminal is currently under construction in the OPSP area. A TDM plan will be required for office/R&D development in the OPSP area and it is anticipated this will encourage mode shifts to the on-site ferry service as well as the nearby BART and Caltrain services currently serving East of 101 commuters. Policy 4.2-G-10 Exempt development within one-quarter mile of a Caltrain or BART station, or a City-designated ferry terminal, from LOS standards. The OPSP area includes an approved ferry terminal currently under construction. LOS standards have been used to determine traffic impacts in this EIR, but the City can take this policy into consideration when deciding whether to adopt a finding of overriding consideration for significant and unavoidable impacts. Policy 4.3-G-1 Develop a comprehensive and integrated system of bikeways that promote bicycle riding for transportation and recreation. The roadways in the OPSP area will include bicycle lanes and the Bay Trail will be connected throughout the OPSP area. Policy 4.3-I-4 Require provision of secure covered bicycle parking at all existing and future multifamily residential, commercial, industrial, and office / institutional uses. Secure bicycle parking will be incorporated into OPSP area and Phase I Project development per the required TDM plans and regulations. CHAPTER 13: LAND USE OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 13-7 Policy 4.3-I-6 As part of any development in Lindenville or East of 101, require project proponents to provide sidewalks and street trees as part of frontage improvements for new development and redevelopment projects. The OPSP proposes sidewalks and street trees as part of frontage improvements (See Figures 3.3 and 3.4). Policy 4.4-G-1 Promote local and regional public transit serving South San Francisco. The location of the OPSP area poises this employment center to take advantage of the on-site ferry terminal currently under construction in addition to the existing East of 101 area transit service from BART, Caltrain and SamTrans (busses). Parks, Recreation and Open Space Policy 5.1-G-1 Develop additional park land in the city, particularly in areas lacking these facilities, to meet the standards of required park acreage for new residents and employees. The proposed OPSP includes approximately 6 acres of dedicated open space and park uses in addition to the Bay Trail (See Figures 3.3 and 3.4). Policy 5.1-G-2 Improve bayfront access along its entire length and endorse the prominence of this important natural asset. The proposed OPSP includes the Bay Trail along all shorelines as well as 3.1 acres of bay front open space and a 3-acre flexible use recreation area in the vicinity of the shore. Two existing marinas and a ferry terminal currently under construction will be accommodated under the OPSP. Further, the main roadway through the OPSP site will be re-aligned, resulting in superior access to the Bay (See Figures 3.3 and 3.4). The proposed OPSP is consistent with the following East of 101 area plan goals: Land Use Goal 1.1 Promote planned industrial, office, and commercial uses in the East of 101 Ares, and discourage other uses that would be inconsistent with these uses. The proposed OPSP includes office/R&D uses and commercial uses consistent with the developing character of the East of 101 Area and this bay side location. Goal 1.2 Encourage development that enhances net revenues to the City. The proposed OPSP includes office/R&D uses and commercial uses that will contribute to revenues to the city while enhancement of the Bay Trail, streetscape, open space and recreation will offer a high quality of development to encourage success of this and surrounding areas. Goal 1.3 Promote development that creates quality jobs for South San Francisco. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 13-8 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT The proposed OPSP includes office/R&D uses, a hotel, and some retail/restaurant uses which will provide a mixture of job opportunities including upper and moderate income salaries. Goal 1.5 Provide for the development of more retail services to serve the employees of the East of 101 Area. The proposed OPSP includes auxiliary commercial uses which can include retail, services and/or restaurant uses. Goal 1.8 Encourage the appropriate development of additional hotel facilities in the East of 101 Area. The proposed OPSP includes the demolition of a 30 room inn and construction of one or two hotels with an aggregate total of up to 350 rooms. Circulation Goal 2.5 Encourage and support transportation modes other than single- occupancy automobiles including ridesharing, bicycling, walking and transit. The proposed OPSP would provide a large employment center near the upcoming ferry terminal and would be expected to link to that and the existing BART and Caltrain commute via bicycle, walking, SamTrans busses and/or shuttles. Goal 2.6 Promote the use of public transit to and within the East of 101 Area. The location of the OPSP area poises this employment center to take advantage of the on-site ferry terminal currently under construction in addition to the existing East of 101 area transit service from BART, Caltrain and SamTrans (busses). Open Space and Recreation Goal 4.1 Encourage uses which take advantage of the San Francisco Bay shoreline and the views associated with the Bay. The proposed OPSP includes the Bay Trail along the shoreline as well as an additional approximately 3.1 acre bayside open space and an approximately 3-acre near-shore recreation area. Additionally, shoreline access and views would be considered a draw for the planned office/R&D buildings as well as the hotel. Goal 4.2 Implementation of the San Francisco Bay Trail Plan in cooperation with the Bay Conservation and Development Commission to secure a continued public access trail along the San Francisco Bay Frontage. The proposed OPSP accommodates and enhances the Bay Trail along the Bay frontage. CHAPTER 13: LAND USE OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 13-9 Design Goal 5.1 Promote high quality site, architectural and landscape design that increases a sense of identity in the East of 101 Area. Development in the OPSP area is subject to the OPSP’s design guidelines to meet this goal. Goal 5.2 Improve streetscape quality of the East of 101 Area through plantings of street trees and provision of entry monuments. The proposed OPSP includes sidewalks, bicycle lanes and landscape improvements along streets as well as plazas and promenades to provide further high-quality connections for pedestrians. Goal 5.3 Protect visually significant features of the East of 101 Area, including views of the Bay and San Bruno Mountain. The proposed OPSP would enhance enjoyment of views of the Bay from the site by bringing in more employees, visitors and residents. The potential to negatively impact views is analyzed in Chapter 4: Aesthetics and has been found to be less than significant. Goal 5.5 Promote public access to views of the San Francisco Bay and to the Bay Trail. The proposed OPSP would enhance enjoyment of views of the Bay from the site by bringing in more employees, visitors and residents and providing bayfront open space and near-shore recreation opportunities. Goal 5.6 Improve the visual quality of the East of 101 Area as seen from Highway 101 along the perimeter of the Area. The proposed OPSP would provide high-quality development in a location visible from portions of Highway 101. The potential to negatively impact views is analyzed in Chapter 4: Aesthetics and has been found to be less than significant. IMPACTS AND MITIGATION MEASURES STANDARDS OF SIGNIFICANCE The following thresholds for measuring environmental impacts are based on CEQA Guidelines thresholds: 1.Would the plan or project physically divide an established community? 2.Would the plan or project conflict with any applicable land use plan, policy or regulation of an agency with jurisdiction over the Project? 3.Would the plan or project conflict with any applicable habitat conservation plan or natural community conservation plan? DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 13-10 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT DIVIDING ESTABLISHED COMMUNITY The proposed OPSP is located at the boundary of the City adjacent to the Bay and represents redevelopment of this commercial area. There are no residential communities in the vicinity, though there are some live-aboard boats in Oyster Point Marina. The alignment of roads to and through the area will be modified, but access will not be reduced. There would be no impact related to the division of an established community. CONFLICT WITH PLANS AND POLICIES Under CEQA, environmental effects must involve an adverse change in physical conditions, as opposed to mere inconsistency with existing policies. That a project or plan might be inconsistent with particular policies in the General Plan, Zoning Ordinance, or other applicable plan, policies or regulations does not necessarily constitute a significant environmental effect.2 Rather, the threshold of significance relates not to all potential inconsistencies, but only inconsistencies with current policies that have been adopted for the purpose of avoiding or mitigating environmental effects. A general discussion of consistency has been included in the setting section above. Policy language is often subject to varying interpretations. The following conclusions are focused on an analysis of current policies and regulations that might lead to adverse effects on the physical environment. This environmental analysis is not intended to pre-suppose the City’s determinations on consistency, or prevent imposition of "conditions of approval" to correct any determined inconsistencies outside of the CEQA forum. Approval of the OPSP will involve a General Plan and Specific Plan amendments as well as revisions to the Zoning Map and Ordinance. Once approved, the OPSP will be consistent with applicable policies and regulations and such amendments and revisions would not be considered to result in environmental impacts beyond those identified as impacts throughout this EIR. No inconsistencies with policies intended to mitigate environmental effects have been identified. While it is in the domain of the City’s decision-makers to decide ultimate project consistency with applicable City plans and policies related to OPSP approval, from a CEQA perspective, the OPSP would not conflict with plans or policies in any way that could have an adverse environmental impact. (No impact.) CONFLICT WITH CONSERVATION PLAN The OPSP area is not within an area covered by a Habitat Conservation Plan (HCP) or Natural Community Conservation Plan (NCCP), or proposed for salt marsh restoration, as discussed in more detail in Chapter 7: Biological Resources. Per the City of South San Francisco Municipal Code, Section 13.30.020, a protected tree is “Any tree with a circumference of forty-eight inches or more when measured fifty-four inches above natural grade.” One or more mature blue gum trees within the ornamental woodland habitat may satisfy size requirements for a “protected tree” under this ordinance. However, these trees are non-native invasive trees that severely degrade natural habitats, as discussed in more detail in Chapter 7: Biological Resources. If any of these trees are found to be of sufficient size to be considered protected under the City’s ordinance, a permit will be required for their removal. This is considered a less-than-significant impact. 2 See Baldwin v. City of Los Angeles (1999) 70 Cal. App 4th 819,8420843 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 14-1 14 NOISE INTRODUCTION This chapter evaluates the potential significance of noise impacts that could result from the OPSP and Phase I Project, including the noise and land use compatibility of proposed uses, as well as, the potential for temporary, periodic, or permanent noise level increases at nearby sensitive receptors attributable to the OPSP. The Setting Section of this report presents the fundamentals of environmental noise and environmental vibration, describes regulatory criteria that would be applicable in the OPSP’s assessment, and summarizes the results of a noise monitoring survey made at the OPSP area. The Impacts and Mitigation Measures Section describes the significance criteria used to evaluate OPSP impacts, provides a discussion of each OPSP impact, and presents mitigation measures necessary to provide a compatible OPSP in relation to surrounding noise sources and sensitive land uses. SETTING FUNDAMENTALS OF ENVIRONMENTAL NOISE Noise is defined as unwanted sound. Airborne sound is a rapid fluctuation of air pressure above and below atmospheric pressure. Sound levels are usually measured and expressed in decibels (dB) with 0 dB corresponding roughly to the threshold of hearing. Decibels and other technical terms are defined in Table 14.1. Most of the sounds that we hear in the environment do not consist of a single frequency, but rather a broad band of frequencies, with each frequency differing in sound level. The intensities of each frequency add together to generate a sound. The method commonly used to quantify environmental sounds consists of evaluating all of the frequencies of a sound in accordance with a weighting that reflects the facts that human hearing is less sensitive at low frequencies and extreme high frequencies than in the frequency mid-range. This is called "A" weighting, and the decibel level so measured is called the A-weighted sound level (dBA). In practice, the level of a sound source is conveniently measured using a sound level meter that includes an electrical filter corresponding to the A-weighting curve. Typical A-weighted levels measured in the environment and in industry are shown in Table 14.2 for different types of noise. Although the A-weighted noise level may adequately indicate the level of environmental noise at any instant in time, community noise levels vary continuously. Most environmental noise includes a conglomeration of noise from distant sources, which create a relatively steady background noise in which no particular source is identifiable. To describe the time-varying character of environmental noise, the statistical noise descriptors, L01, L10, L50, and L90, are commonly used. They are the A- weighted noise levels equaled or exceeded during 1%, 10%, 50%, and 90% of a stated time period. A single number descriptor called the Leq is also widely used. The Leq is the average A-weighted noise level during a stated period of time. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 14-2 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT TABLE 14.1 DEFINTIONS OF ACOUSTICAL TERMS IN THIS REPORT Term Definitions Decibel, dB A unit describing, the amplitude of sound, equal to 20 times the logarithm to the base 10 of the ratio of the pressure of the sound measured to the reference pressure. The reference pressure for air is 20. Sound Pressure Level Sound pressure is the sound force per unit area, usually expressed in micro Pascals (or 20 micro Newtons per square meter), where 1 Pascal is the pressure resulting from a force of 1 Newton exerted over an area of 1 square meter. The sound pressure level is expressed in decibels as 20 times the logarithm to the base 10 of the ratio between the pressures exerted by the sound to a reference sound pressure (e.g., 20 micro Pascals). Sound pressure level is the quantity that is directly measured by a sound level meter. Frequency, Hz The number of complete pressure fluctuations per second above and below atmospheric pressure. Normal human hearing is between 20 Hz and 20,000 Hz. Infrasonic sound are below 20 Hz and Ultrasonic sounds are above 20,000 Hz. A-Weighted Sound Level, dBA The sound pressure level in decibels as measured on a sound level meter using the A-weighting filter network. The A-weighting filter de-emphasizes the very low and very high frequency components of the sound in a manner similar to the frequency response of the human ear and correlates well with subjective reactions to noise. Equivalent Noise Level, Leq The average A-weighted noise level during the measurement period. Lmax, Lmin The maximum and minimum A-weighted noise level during the measurement period. L01, L10, L50, L90 The A-weighted noise levels that are exceeded 1%, 10%, 50%, and 90% of the time during the measurement period. Day/Night Noise Level, Ldn or DNL The average A-weighted noise level during a 24-hour day, obtained after addition of 10 decibels to levels measured in the night between 10:00 pm and 7:00 am. Community Noise Equivalent Level, CNEL The average A-weighted noise level during a 24-hour day, obtained after addition of 5 decibels in the evening from 7:00 pm to 10:00 pm and after addition of 10 decibels to sound levels measured in the night between 10:00 pm and 7:00 am. Ambient Noise Level The composite of noise from all sources near and far. The normal or existing level of environmental noise at a given location. Intrusive That noise which intrudes over and above the existing ambient noise at a given location. The relative intrusiveness of a sound depends upon its amplitude, duration, frequency, and time of occurrence and tonal or informational content as well as the prevailing ambient noise level.

Several different methods are typically used to quantify vibration amplitude. One is the Peak Particle Velocity (PPV) and another is the Root Mean Square (RMS) velocity. The PPV is defined as the maximum instantaneous positive or negative peak of the vibration wave. The RMS velocity is defined as the average of the squared amplitude of the signal. The PPV and RMS vibration velocity amplitudes are used to evaluate human response to vibration. In this section, a PPV descriptor with units of mm/sec or in/sec is used to evaluate construction generated vibration for building damage and human complaints. Table 14.3 displays the reactions of people and the effects on buildings that continuous vibration levels produce. The annoyance levels shown in Table 14.3 should be interpreted with care since vibration may be found to be annoying at much lower levels than those shown, depending on the level of activity or the sensitivity of the individual. To sensitive individuals, vibrations approaching the threshold of perception can be annoying. Low-level vibrations frequently cause irritating secondary vibration, such as a slight rattling of windows, doors or stacked dishes. The rattling sound can give rise to exaggerated vibration complaints, even though there is very little risk of actual structural damage. In high noise environments, which are more prevalent where groundborne vibration approaches perceptible levels, this rattling phenomenon may also be produced by loud airborne environmental noise causing induced vibration in exterior doors and windows. Construction activities can cause vibration that varies in intensity depending on several factors. The use of pile driving and vibratory compaction equipment typically generate the highest construction related ground-borne vibration levels. Because of the impulsive nature of such activities, the use of the peak particle velocity descriptor (PPV) has been routinely used to measure and assess ground-borne vibration and almost exclusively to assess the potential of vibration to induce structural damage and the degree of annoyance for humans. The two primary concerns with construction-induced vibration, the potential to damage a structure and the potential to interfere with the enjoyment of life are evaluated against different vibration limits. Studies have shown that the threshold of perception for average persons is in the range of 0.008 to 0.012 in/sec PPV. Human perception to vibration varies with the individual and is a function of physical setting and the type of vibration. Persons exposed to elevated ambient vibration levels such as people in an urban environment may tolerate a higher vibration level. Structural damage can be classified as cosmetic only, such as minor cracking of building elements, or may threaten the integrity of the building. Safe vibration limits that can be applied to assess the potential for damaging a structure vary by researcher and there is no general consensus as to what amount of vibration may pose a threat for structural damage to the building. Construction-induced vibration that can be detrimental to the building is very rare and has only been observed in instances where the structure is at a high state of disrepair and the construction activity occurs immediately adjacent to the structure. EXISTING NOISE ENVIRONMENT The OPSP area is located in South San Francisco, east of Highway 101, in the City’s industrial and technological core area. Land uses in the vicinity of the OPSP area include commercial, industrial, office, recreational/open space, and hotel uses. The major arterial street that serves the OPSP area vicinity is Oyster Point Boulevard. CHAPTER 14: NOISE OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 14-5 TABLE 14.3 REACTION OF PEOPLE AND DAMAGE TO BUILDINGS FOR CONTINUOUS VIBRATION LEVELS Vibration Level, PPV (in/sec) Human Reaction Effect on Buildings 0.006 to 0.019 Threshold of perception, Possibility of intrusion Vibration unlikely to cause damage of any type 0.08 Vibrations readily perceptible Recommended upper level of the vibration to which ruins and ancient monuments should be subjected 0.10 Level at which continuous vibrations begin to annoy people Virtually no risk of “architectural” damage to normal buildings 0.20 Vibrations annoying to people in buildings Threshold at which there is a risk of “architectural” damage to normal dwellings such as plastered walls or ceilings. 0.4 to 0.6 Vibrations considered unpleasant by people subjected to continuous vibrations Vibration at this level would cause “architectural” damage and possibly minor structural damage.

A noise monitoring survey was conducted from January 14, 2010 to January 15, 2010 to quantify the existing noise environment at the site and in the OPSP area vicinity. The noise monitoring survey included one long-term noise measurement (LT-1), and four short-term measurements (ST-1 through ST-4) as indicated on Figure 14.1. The noise environment at the site results primarily from local traffic noise generated along arterial streets serving the plan area, distant traffic noise from Highway 101, and aircraft over flights associated with San Francisco International Airport (SFO). Figure 1 in Appendix D shows the daily trend in noise levels for the long-term noise measurement. Noise measurement location LT-1 was approximately 175 feet from the nearest boat slip of the southern portion of the Oyster Point Marina. This noise measurement location represented the noise environment resulting from local traffic in the marina parking lot, distant Highway 101, and aircraft noise. Hourly average noise levels typically ranged from 58 to 64 dBA Leq during the day, and from 44 to 62 dBA Leq at night. The day-night average noise level at this measurement location was 63 dBA CNEL. Short-term (ten-minute) noise measurements were made at four additional locations within the Specific OPSP area to complete the noise monitoring survey. Short-term noise measurement ST-1 was made at the southeast corner of the OPSP area, near the existing boat ramp facility. The average noise level during this time period was 61 dBA Leq. Short-term noise measurement ST-2 was conducted at a distance of approximately 55 feet from the center of Marina Boulevard, at the entrance gate to the marina. The average noise level during this time period was 62 dBA Leq. Short-term noise measurement ST-3 was conducted at a distance of 57 feet from the center of Oyster Point Boulevard. The average noise level during this time period was 64 dBA Leq. Short-term noise measurement ST-4 was conducted approximately 55 feet from the center of Oyster Point Boulevard adjacent to Eccles Avenue. The average noise level during this time period was 68 dBA Leq.Table 14.4 summarizes the results of these measurements.

CHAPTER 14: NOISE OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 14-9 REGULATORY SETTING The proposed OPSP and Phase I Project would be subject to noise-related regulations, plans, and policies established within documents prepared by the State of California and the City of South San Francisco. These planning documents are implemented during the environmental review process to limit noise exposure at existing and proposed noise sensitive land uses. Applicable planning documents include: (1) the California Environmental Quality Act (CEQA) Guidelines, Appendix G, (3) the California State Building Code, (3) the City of South San Francisco Noise Element of the General Plan, and (4) the City of South San Francisco Municipal Code. Regulations, plans, and policies presented within these documents form the basis of the significance criteria used to assess OPSP and Phase I Project impacts. 2007 California Building Code The development of new dormitory, apartment and other multi-family housing types, other than detached single family dwellings are subject to the environmental noise limits set forth in the 2007 California Building Code (Chapter 12, Appendix Section 1207.11.2). The noise limit is a maximum interior noise level of 45 dBA Ldn/CNEL. Where exterior noise levels exceed 60 dBA Ldn/CNEL, a report must be submitted with the building plans describing the noise control measures that have been incorporated into the design of the project to meet the noise limit. City of South San Francisco General Plan The Noise Element of the City of South San Francisco General Plan addresses noise sources in the community and identifies ways to reduce the impacts of these noise sources. The Element contains policies and programs to achieve and maintain noise levels compatible with various types of land uses. Land uses that are sensitive to noise are identified and future noise generating land uses are located so that they do not impact those sensitive areas. The following are the guiding and implementation policies contained in the Noise Element of the City of South San Francisco’s General Plan. Guiding Policies Policy 9-G-1: Protect public health and welfare by eliminating or minimizing the effects of existing noise problems, and by preventing increased noise levels in the future. Policy 9-G-2: Continue efforts to incorporate noise considerations into land use planning decisions, and guide the location and design of transportation DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 14-10 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT facilities to minimize the effects of noise on adjacent land uses. Implementation Policies Implementation Policy 9-I-4. Ensure that new noise-sensitive uses, including schools, hospitals, churches, and homes, in areas near roadways identified as impacting sensitive receptors by producing noise levels greater than 65 dBA CNEL, incorporate mitigation measures to ensure that interior noise levels do not exceed 45 dBA CNEL. Implementation Policy 9-I-5. Require that applicants for new noise-sensitive developments in areas subject to noise generators producing noise levels greater than 65 dBA CNEL, obtain the services of a professional acoustical engineer to provide a technical analysis and design of mitigation measures. Implementation Policy 9-I-6. Where site conditions permit, require noise buffering for all noise- sensitive development subject to noise generators producing noise levels greater than 65 dBA CNEL. This noise attenuation method should avoid the use of visible sound walls, where practical. Implementation Policy 9-I-7. Require the control of noise at source through site design, building design, landscaping, hours of operation, and other techniques, for new developments deemed to be noise generators. City of South San Francisco Municipal Code The noise regulations of the City of South San Francisco’s Municipal Code are contained in Chapter 8.32 of the Code. The following contain the quantitative noise limits and construction noise regulations. 8.32.030 Maximum permissible sound levels. (a) It is unlawful for any person to operate or cause to be operated any source of sound at any location within the city or allow the creation of any noise on property owned, leased, occupied or otherwise controlled by such person, which causes the noise level when measured on any other property to exceed: (1) The noise level standard for that land use as specified in Table 8.32.030 for a cumulative period of more than thirty minutes in any hour; (2) The noise level standard plus five dB for a cumulative period of more than fifteen minutes in any hour; (3) The noise level standard plus ten dB for a cumulative period of more than five minutes in any hour; (4) The noise level standard plus fifteen dB for a cumulative period of more than one minute in any hour; or (5) The noise level standard or the maximum measured ambient level, plus twenty dB for any period of time. (b) If the measured ambient level for any area is higher than the standard set in Table 8.32.030, then the ambient shall be the base noise level standard for purposes of subsection (a)(1) of this section. In such cases, the noise levels for purposes of subsections (a)(2) through (a)(5) of this section shall be increased in five dB increments above the ambient. CHAPTER 14: NOISE OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 14-11 (c) If the measurement location is on a boundary between two different zones, the noise level standard shall be that applicable to the lower noise zone plus five dB. (d)Notwithstanding any other provisions of this chapter, no person shall willfully make or continue, or cause to be made or continued, any loud, unnecessary or unusual noise which disturbs the peace or quiet of any neighborhood.

If the device is housed within a structure or trailer on the property, the measurement shall be made outside the structure at a distance as close to twenty-five feet from the equipment as possible. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 14-12 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT The noise level at any point outside of the property plane of the project shall not exceed ninety dB. (Ord. 1088 § 1 (part), 1990) IMPACTS AND MITIGATION MEASURES SIGNIFICANCE CRITERIA Appendix G of the CEQA Guidelines (Environmental Checklist) contains a list of noise effects that may be considered significant. Potential noise effects from a project are considered significant if any of the following occur: x exposure of persons to or generation of noise levels in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies; x exposure of persons to or generation of excessive ground-borne vibration or ground-borne noise levels; x a substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project; x a substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels existing without the project; x for a project located within an airport land use plan or where such a plan has not been adopted within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels; x for a project within the vicinity of a private airstrip, would the project expose people residing or working in the project area to excessive noise levels. The following quantifiable criteria were used to evaluate the significance of impacts: Noise and Land Use Compatibility. A significant noise impact would be identified where noise- sensitive land uses are proposed in exterior noise environments exceeding 65 dBA CNEL and commercial land uses exceed 70 dBA CNEL. Interior noise levels within residential land uses in excess of 45 dBA CNEL would also result in a significant noise impact. Substantial Permanent Increase to Noise Levels. A significant noise impact would be identified where project-generated traffic would increase traffic noise levels at existing noise-sensitive land uses by 3 dBA CNEL or more. A 3 dBA CNEL increase in noise is used as a threshold because this is the level at which the human ear can perceive an increase in noise, below that the increase would not be noticeable. Substantial Temporary Noise from Construction. Construction activities generate temporary noise level increases in the vicinity of project sites. Since noise generated by construction would be short-term and vary considerably day-to-day, construction noise is evaluated somewhat differently than operational noise. When construction activities are predicted to cause prolonged interference with normal activities at noise-sensitive receptors, generate noise levels in excess of 60 dBA Leq, and exceed ambient noise levels by 5 dBA Leq or more, the impact would be considered significant. Prolonged interference is defined as a substantial noise level increase that occurs for one year or more. CHAPTER 14: NOISE OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 14-13 APPROPRIATENESS OF NOISE LEVELS FOR PROPOSED USES Impact Noise-1: Noise Levels at Proposed Uses. The OPSP will not expose persons to or generation of noise levels in excess of standard established by the City of South San Francisco. This is a less-than-significant impact. Exterior Noise Levels Office/R&D buildings developed as part of the programmatic OPSP are proposed east and west of Oyster Point Boulevard on the northern portion of the site. Future exterior noise levels along Oyster Point Boulevard are calculated to be approximately 68 dBA CNEL at a distance of 55 feet from the roadway. The noise environment at portions of the OPSP area planned for office/research and development (R&D) would not exceed the City’s noise level goal for exterior noise (70 dBA CNEL) as a result of transportation noise sources in the site vicinity (e.g., Oyster Point Boulevard, Marina Boulevard and aircraft over flights). Office/R&D buildings developed as part of Phase I Project are proposed south of the intersection of Oyster Point Boulevard and Marina Boulevard. Future exterior noise levels along this portion of Oyster Point Boulevard are calculated to be approximately 67 dBA CNEL at a distance of 55 feet from the roadway. Noise levels at Phase I Project buildings would not exceed the City’s noise level goal for exterior noise (70 dBA CNEL) as a result of transportation noise sources. The future hotel site is proposed east of the office/R&D plaza, along Marina Boulevard. Grading and site preparation for the hotel and accompanying retail uses are all that are proposed for Phase I of the OPSP. Future exterior noise levels at the proposed hotel site are calculated to be approximately 65 dBA CNEL. Noise levels at a future hotel and retail/restaurant site would not exceed the City’s noise level goal for exterior noise (65 dBA CNEL) as a result of transportation noise sources. Future open space is proposed east of the intersection of Marina Boulevard and Oyster Point Boulevard, adjacent to the Oyster Point Marina. Future exterior noise levels at the proposed open space use are calculated to be approximately 64 dBA CNEL. Noise levels at future open space uses would not exceed the City’s noise level goal for exterior noise (75 dBA CNEL) as a result of transportation noise sources. Interior Noise Levels For an office development, the noise and land use compatibility guidelines are designed to screen projects and provide guidance in determining when special building sound insulation treatments may be necessary in order to adequately control the intrusion of environmental noise. The goal for hourly average noise levels inside offices varies, depending upon the type of office space. Typically, traffic noise levels should be reduced to an hourly average noise level of between 35 and 45 dBA Leq. Standard office construction normally provides about 30 dBA of noise reduction when going from outside to inside. Predicted interior noise levels at the offices on the northern facades of the Phase I office/R&D building overlooking Oyster Point Boulevard would be about 37 dBA Leq assuming standard office construction. Predicted interior noise levels at the offices on the eastern and western facades of the office buildings overlooking Marina Boulevard would be about 34 dBA Leq assuming standard office construction. Portions of the office buildings located further away from these roadways or in acoustically shielded areas will experience even lower noise levels. Noise levels at the proposed office buildings will comply with City of South San Francisco standards (45 dBA CNEL or less) and would result in a less-than significant impact. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 14-14 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT The California State Building Code and the City of South San Francisco General plan require interior noise levels to be maintained at or below 45 dBA CNEL in noise sensitive land uses. Predicted interior noise levels at the proposed hotel site would be about 35 dBA CNEL assuming standard hotel construction. Interior noise levels at the proposed hotel will comply with the State Building Code and City of South San Francisco standards and would result in a less-than-significant impact. PERMANENT NOISE LEVEL INCREASES Impact Noise-2: Projected Noise Increases. Following construction, the OPSP will not create a substantial permanent increase in ambient noise levels in the project vicinity above existing without the project. This is aless-than-significantimpact. On-Site Operational Noise Increases The OPSP allows for the development of retail/restaurant as accessory uses in the same location with office/R&D. Noise sources at these commercial uses could include loading docks, outdoor mechanical equipment (e.g., heating and cooling equipment, etc.), and parking lots. Noise associated with the use of parking lots would include vehicle circulation, loud engines, car alarms, squealing tires, door slams, and human voices. The maximum sound (Lmax) of a passing car at 15 mph typically ranges from 43 dBA to 53 dBA at 150 feet. The noise generated during an engine start is similar. Door slams create lower noise levels. Hourly average noise levels resulting from all of these noise-generating activities in a busy parking lot could range from 35 dBA to 45 dBA Leq at a distance of 150 feet from the parking area. Heating, ventilation, and cooling equipment could generate noise levels in the range of 50 dBA to 70 dBA Leq at 150 feet depending on the number, type, and size of the proposed equipment. Trash compactors typically generate maximum noise levels of 40 to 50 dBA at 150 feet, depending on the power rating and enclosure characteristics. Recreation fields and open space are also sources of community noise. Proposed fields could contain one or more of the following amenities that are often part of recreation fields: playfields, open turf area, picnic tables with barbeques, trails, etc. Noise generated by a particular park is a function of the amenities provided, groups which use the facilities, and the timing and duration of use. For normal active park events such as soccer games, baseball games, dog parks, etc., average noise levels of about 55 to 60 dBA Leq could be expected at a distance of 150 feet from the center of activities. The nearest docks at the marina are located approximately 600 feet from the proposed recreation fields. Noise generated by such active fields would generate noise levels of approximately 43 to 48 dBA Leq. Noise from passive open space areas and recreation fields would not exceed standards set forth in the City’s Municipal Code. The nearest noise sensitive receptors are live-aboard boats located in the marinas and are located approximately 150 to 550 feet from shore. Noise levels associated with commercial operations would generally be less than existing ambient noise levels and would not exceed City Municipal Code standards (60 dBA L50 during nighttime hours and 65 dBA L50 at night) for stationary noise sources at the nearest receptors within and around the mixed-use developments. Traffic Noise Increases Traffic volume information was reviewed at study area intersections around the plan area. Traffic volumes under the “Existing”, “Base Case”, “Base Case plus project” traffic scenarios were compared to CHAPTER 14: NOISE OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 14-15 calculate the relative increase in traffic noise attributable to the proposed OPSP and Phase I Project. A noise impact would be identified at noise-sensitive land uses where the OPSP would result in a noise level increase of 3 dBA CNEL or more. There are no noise sensitive receivers located on the roadways surrounding the site. The comparison of base case and base case plus project traffic volumes indicates that the OPSP would not substantially increase traffic noise levels at noise sensitive receptors in the vicinity. The OPSP would increase traffic noise levels by 0 to 2 dBA CNEL, and the impact would be less than significant. CUMULATIVE NOISE LEVEL INCREASES Impact Noise-3: Cumulative Noise Increases. Traffic volumes along roadways serving the OPSP area will increase as a result of cumulative growth planned in and around the City of South San Francisco. The OPSP would not make a “cumulatively considerable” contribution to cumulative traffic noise increases at noise sensitive receptors within the OPSP area. This is aless-than-significantcumulative impact. The Project would result in a significant cumulative traffic noise impact if existing sensitive receptors would be exposed to cumulative traffic noise level increases greater than 3 dBA CNEL above existing traffic noise levels and if the Project would make a “cumulatively considerable” contribution to the overall traffic noise level increase. A “cumulatively considerable” contribution would be defined as an increase of 1 dBA CNEL or more attributable solely to the proposed project. Cumulative traffic noise levels are calculated to increase substantially along roadways serving the project site because of cumulative growth forecast in local General Plans. Project traffic volumes under the “Existing”, “Base Case”, and “Base Case plus project” traffic scenarios were compared to calculate the relative increase in traffic noise attributable to the proposed project. The comparison of base case and base case plus project traffic volumes indicates that the project would not substantially increase traffic noise levels at noise sensitive receptors in the vicinity. Cumulative traffic noise level increases were calculated by comparing “2035 Base Case plus project” traffic volumes to “2035 Base Case without project” volumes. The OPSP’s contribution to cumulative noise level increases would be 1 to 2 dBA CNEL along roadways surrounding the OPSP area, however, there are no noise sensitive receptors located on the affected roadway segments. This increase in noise would not be considered substantial. The OPSP would not make a cumulatively considerable contribution to increased noise levels at noise sensitive receptors resulting from the build-out of the area. VIBRATION Impact Noise-4: Groundborne Vibration. The OPSP is not anticipated to expose persons to or generation of excessive groundborne vibration or groundborne noise levels.This is aless-than-significant impact. The proposed uses are not the type that will generate substantial groundborne vibration during operations. The nearest noise-sensitive receptors to the OPSP area are live-aboard boats located in the marinas. Any construction related groundborne vibrations would not be felt at adjacent noise-sensitive receptors because they are located on water and groundborne vibration would not be transmitted from the ground to the boats. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 14-16 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT For structural damage, the California Department of Transportation uses a vibration limit of 0.2 in/sec, PPV for buildings that are found to be structurally sound but where structural damage is a major concern. Office buildings located adjacent to the proposed OPSP are located approximately 100 feet away from temporary construction activities and it is not anticipated that construction activities will result in vibration levels that exceed 0.2 in/sec PPV. Table 14.5 depicts vibration source levels for various types of construction equipment. TABLE 14.5: VIBRATION SOURCE LEVELS FOR CONSTRUCTION EQUIPMENT1 Equipment PPV at 100 ft. (in/sec) upper range 0.145 Pile Driver (Impact) typical 0.081 upper range 0.092 Pile Driver (Sonic) typical 0.021 Clam shovel drop 0.025 in soil 0.001 Hydromill (slurry wall) in rock 0.002 Vibratory Roller 0.026 Hoe Ram 0.011 Large bulldozer 0.011 Caisson drilling 0.011 Loaded trucks 0.010 Jackhammer 0.004 Small bulldozer 0.000 CONSTRUCTION NOISE Impact Noise-5: Construction Noise. The OPSP area includes existing sensitive receptors consisting of live-aboard boats in the marinas. In periods of construction, during construction hours, noise generated by construction on the site would substantially increase noise levels at residential land uses in the vicinity of the site temporarily above levels existing without the project. This is asignificant impact. Noise impacts resulting from construction depend on the noise generated by various pieces of construction equipment, the timing and duration of noise generating activities, and the distance between construction noise sources and noise sensitive receptors. Where noise from construction activities exceeds 60 dBA Leq and exceeds the ambient noise environment by at least 5 dBA Leq at noise-sensitive uses in the OPSP vicinity for a period of more than one construction season, the impact would be considered significant. Table 1 in Appendix D depicts the range of A-weighted noise levels generated by specific pieces of construction equipment at a distance of 50 feet. Table 14.6 presents typical ranges in hourly average noise levels at a distance of 50 feet generated different phases of construction. Construction activities 1 Transit Noise and Vibration Impact Assessment, United States Department of Transportation, Office of Planning and Environment, Federal Transit Administration, May 2006. CHAPTER 14: NOISE OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 14-17 generate considerable amounts of noise, especially during the demolition phase and the construction of OPSP infrastructure when heavy equipment is used. Typical hourly average construction generated noise levels are about 75 dBA to 89 dBA measured at a distance of 50 feet from the center of the site during busy construction periods (e.g., earth moving equipment, impact tools, etc.). Construction generated noise levels drop off at a rate of about 6 dBA per doubling of distance between the source and receptor.

Construction projects of this type are typically built out over more than one construction season, and some construction methods generate higher noise levels and noise that would be considered impulsive. Phase I demolition, landfill materials relocation and cap upgrades, grading and infrastructure construction is predicted to last approximately 12 months and Phase I vertical construction is anticipated to last approximately 20 months, including seating the piles. Adding in interior build-out and paving and landscaping of the site, the entire Phase I construction schedule is anticipated to span approximately 3.5 year and could start as early as 2011. Construction noise impacts primarily result when construction activities occur during noise-sensitive times of the day (early morning, evening, or nighttime hours), the construction occurs in areas immediately adjoining noise sensitive receptors, or when construction durations last over extended periods of time. Limiting the hours when construction can occur to daytime hours is often a simple method to reduce the potential for noise impacts. In areas immediately adjacent to construction, controls such as constructing temporary noise barriers and utilizing “quiet” construction equipment can also reduce the potential for noise impacts. The nearest existing noise sensitive receptors are about 150 feet from the OPSP area. Hourly average noise levels would range from 71 dBA to 78 dBA during the busiest construction periods along the perimeter of the site. As construction focuses on other portions of the OPSP located further away from these receptors, noise levels would be lower. Construction noise levels are anticipated to exceed 60 dBA Leq and the ambient by 5 dBA Leq or more over extended periods of time. It is conceivable that a particular receptor or group of receptors would be subject to construction noise levels in excess of 60 dBA Leq and the ambient by 5 dBA Leq for durations exceeding one construction season. The construction of the OPSP would result in a DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 14-18 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT significant temporary noise level increase at on-site noise-sensitive receptors consisting of live-aboard boats in the marinas. Noise-generating activities at the construction site or in areas adjacent to the construction site will be restricted to the hours of 8:00 a.m. to 8:00 p.m. Monday through Friday, 9:00 a.m. to 8:00 p.m. on Saturday, and from 10:00 a.m. to 6:00 p.m. on Sundays and holidays. The City of San Francisco Municipal Code also requires that no individual piece of equipment shall produce a noise level exceeding ninety dB at a distance of twenty-five feet. If the device is housed within a structure or trailer on the property, the measurement shall be made outside the structure at a distance as close to twenty-five feet from the equipment as possible. The noise level at any point outside the property plane of the OPSP area shall not exceed ninety dB. Mitigation Measure Noise-5: Construction Noise. To reduce noise levels generated by construction, the following standard construction noise control measures shall be included in all construction projects within the OPSP area. x Equip all internal combustion engine driven equipment with intake and exhaust mufflers that are in good condition and appropriate for the equipment. x Unnecessary idling of internal combustion engines should be strictly prohibited. x Locate stationary noise generating equipment such as air compressors or portable power generators as far as possible from sensitive receptors. Construct temporary noise barriers to screen stationary noise generating equipment when located near adjoining sensitive receptors. Temporary noise barriers could reduce construction noise levels by 5 dBA. x Utilize "quiet" air compressors and other stationary noise sources where technology exists. x Route all construction traffic to and from the OPSP area via designated truck routes where possible. Prohibit construction related heavy truck traffic in residential areas where feasible. x Control noise from construction workers’ radios to a point that they are not audible at existing residences bordering the OPSP area. x The contractor shall prepare and submit to the City for approval a detailed construction plan identifying the schedule for major noise-generating construction activities. x Designate a "disturbance coordinator" who would be responsible for responding to any local complaints about construction noise. The disturbance coordinator will determine the cause of the noise complaint (e.g., starting too early, bad muffler, etc.) and will require that reasonable measures warranted to correct the problem be implemented. Conspicuously post a telephone number for the disturbance coordinator at the construction site and include it in the notice sent to neighbors regarding the construction schedule. CHAPTER 14: NOISE OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 14-19 x For pile driving activities, consider a) pre-drilling foundation pile holes to minimize the number of impacts required to seat the pile, b) using multiple pile driving rigs to expedite this phase of construction, and/or c) the use of “acoustical blankets” for receivers located within 100 feet of the site. Although the above measures would reduce noise generated by the construction of the proposed OPSP and Phase I Project, the impact would remain significant and unavoidable as a result of the extended period of time that adjacent receivers would be exposed to construction noise, though the noise would be episodic and temporary in nature. AIRCRAFT NOISE Impact Noise-6: Aircraft Noise. Proposed uses developed at the site would be exposed to intermittent noise from aircraft associated with San Francisco International Airport. The exterior noise environment at the OPSP area would be considered compatible with proposed sensitive uses. This is aless-than-significant impact. Intermittent aircraft noise resulting from operations of San Francisco International Airport would be audible at the OPSP area, but aircraft noise levels would not be considered incompatible with the proposed uses. The City of South San Francisco General Plan noise contour map2 shows where the projected 2006 65 dBA CNEL contours are located. According to the data on the contour map, the OPSP area would be located well outside the airport’s 65 dBA CNEL noise contour in an area that would be defined as noise-affected. The OPSP area is also located more than 2 miles from the San Francisco International Airport. The exterior noise environment at the OPSP area resulting from aircraft would be considered compatible with proposed sensitive uses. 2 San Mateo County Airport Land Use OPSP; San Francisco International Airport.

OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 15-1 15 POPULATION, PUBLIC SERVICES AND RECREATION INTRODUCTION This chapter of the Draft EIR contains discussion regarding three CEQA topic areas related to the increase in employees at the site: Population/Housing, Public Services, and Recreation. It describes the change in employment n the OPSP area and analyzes the potential for impacts on population and housing, public services, and recreation resulting from implementation of the proposed project. Preparation of this section used data from various sources. These sources include the Association of Bay Area Governments (“ABAG”) and the City of South San Francisco General Plan Housing Element (“Housing Element”), updated in June 2009. POPULATION/HOUSING SETTING The Association of Bay Area Governments (ABAG) Regional Comprehensive Plan and Guide governs regulations applicable to population and housing for the proposed OPSP. California’s Housing Element Law assigns responsibility for developing projections of regional housing need and for allocating a share of this need to localities within the region to regional councils of government. For the San Francisco Bay Area, these determinations are prepared by ABAG and documented in its San Francisco Bay Area Housing Needs Plan (plan). The plan documents the Regional Housing Needs Allocation (RHNA) for the Bay Area. The RHNA process is a state mandate, devised to address the need for and planning of housing across a range of affordability and in all communities throughout the state. Each jurisdiction within the Bay Area (101 cities, nine counties) is given a share of the anticipated regional housing need. The Bay Area's regional housing need is specified by the California State Department of Housing and Community Development (HCD) and finalized through negotiations with ABAG. The timeframe for this RHNA process is 2007 through 2014 (a seven year planning period). South San Francisco General Plan, Municipal Code, and the General Plan Housing Element govern regulations applicable to population and housing for the proposed OPSP. The City’s General Plan Housing Element seeks to maximize residential development opportunities on infill sites. The intent here is that increased residential development within the City will help alleviate traffic impacts resulting from economic development, and provide residential opportunities to those that work in the City but currently live elsewhere. The State of California’s Housing and Community Development Department works with regional Councils of Governments (COGs) to determine the amount of housing needed within the region. ABAG is this region’s COG. The determination of housing need is based on existing need and DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 15-2 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT estimated population growth. Need is determined for households in all income categories: very-low, low, moderate and above-moderate incomes. Once the total regional need is determined, ABAG works with local governments and others to allocate the total need to individual cities and counties. Local governments are then required to plan where and how the allocated housing units will be developed within their communities. This is done through the Housing Element of each local government’s General Plan. Based on a methodology that weighs a number of factors (e.g., projected population growth, employment, commute patterns, available sites), ABAG determines quantifiable needs for housing units in the region according to various income categories. ABAG publishes an annual report that discusses housing issues of importance to the San Francisco Bay Area. The 2008 report, San Francisco Bay Area Housing Needs Plan, 2007-2014, explains the Regional Housing Needs Allocation (RHNA) process and outcomes. The San Francisco Bay Area Housing Needs Plan, 2007-2014, allocates 1,635 housing units to the City of South San Francisco. The City’s current Housing Element was adopted in June 2009 and addressed ABAG’s previous RHNA. The planning horizon for the Housing Element extends from 2007 to 2014. Between January 1, 2007, and June 30, 2009, South San Francisco built 815 new units. In addition there were 15 housing units that were substantially rehabilitated and converted from market rate to affordable housing. Consequently, the City has a remaining balance of 805 units which it must plan for during the remainder of the planning period. According to the General Plan Housing Element, South San Francisco has an adequate number of sites to accommodate its share of the regional housing need between 2007 and 2014. There is sufficient land to support the production of more than 1,195 new housing units. According to the General Plan Housing Element, the City has a history of imbalance in its jobs/housing ratio. South San Francisco is a “jobs rich” City with substantial in-commuting from other jurisdictions. In 2007, there were approximately 30,000 employed residents in the City compared to 50,000 jobs, a ratio of 1.7 jobs per every working resident of the City. By comparison, in 2007 San Mateo County had a much closer balance between the number of employed residents and total jobs with approximately 370,000 employed residents and 340,000 jobs, a ratio of 0.9 jobs per every working resident of the County. The City’s jobs-housing balance is a measure for land use planning purposes. The City does not currently have an adopted jobs-housing ratio goal. Given that much of the land in the City, including all of the East of 101 Area, is not zoned for residential development, attainment of a jobs and housing balance in South San Francisco is doubtful. On the other hand, continued job growth in the City will promote a greater regional balance between jobs and housing. As an inner Bay Area community well served by all modes of transit—including air and rail, BART and ferry service in the near future—future employees from and traveling to the City will have varied means of reaching employment sites. As South San Francisco’s employment base, the East of 101 Area is expected to accommodate a major share of South San Francisco’s new non-residential development. While under the General Plan total building floor space is expected to increase by about 50 percent (from 12.0 million square feet [sf] to about 17.4 million sf), overall employment levels are expected to more than double (from 22,200 in 1997 to 42,000 at General Plan buildout in 2020). Consistent with this, ABAG Projections 2009 projects the City’s total employment number to be 48,290 in 2020. This represents an increase in employment in the City of 3,110 jobs from 2005 to 2015 and 2,940 jobs from 2015 to 2020. Both the Traffic Impact Fee Study Update and the ABAG Projections 2009 are based upon existing planning documentation; therefore, as new projects are CHAPTER 15: POPULATION, PUBLIC SERVICES AND RECREATION OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 15-3 approved, the projection numbers would also change. As such, the employment buildout projections are not treated as limits, rather they project the employment for the region based upon the best available data. POPULATION/HOUSING IMPACT ANALYSIS Standards of Significance Under the CEQA Guidelines, Appendix G – Environmental Checklist Form, development of the OPSP site as proposed would have a significant environmental impact if it were to result in: 1.The inducement of substantial population growth in an area either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure); or 2.The displacement of substantial numbers of existing housing, necessitating the construction of replacement housing elsewhere; or 3.The displacement of substantial numbers of people, necessitating the construction of replacement housing elsewhere. Displacement of Housing or People The only residences in the OPSP area are live-aboard boats in the marinas, which are not proposed to be affected by the OPSP. Thus, no residents would be displaced, and construction of replacement housing elsewhere would not be necessitated. Therefore, there would be no impact and no mitigation measures are required. Inducing Population Growth Impact Pop-1: Indirect Population Growth. As a large employment center, build-out of both Phase I Project and the entire OPSP would indirectly induce population growth through creation of additional jobs. However, these additional jobs would help in part to correct job deficiencies region-wide and the impact would be considered less-than-significant. The OPSP does not propose any housing. The existing 403,000 square feet of light industrial uses could support at least 733 employees and likely more depending on the mix of uses. Additionally, there are approximately 123 or more employees in the office buildings, boat and motor mart, and inn currently on the Phase I site. The Phase I Project and subsequent phases of the OPSP propose the construction of up to 600,000 square feet of office/R&D and a maximum of 2,300,000 square feet of office/R&D uses over subsequent phases in addition to up to 350 hotel rooms with up to 40,000 square feet of retail/restaurant uses that will in part replace existing uses. This could result in a net increase of approximately 1,310 employees for the Phase I Project and a total net increase of approximately 5,965 employees for the full build-out of the OPSP. ABAG projects an increase in employment in the City of 3,110 jobs from 2005 to 2015 and 2,940 jobs from 2015 to 2020 for a total increase of 6,050 by 2020. Therefore, the Phase I Project and OPSP’s contributions to the increase in employment in the City would be within ABAG’s employment projections for the City for both the years of 2015 and 2020. The increase in employees in the City could result in an increase in demand for housing. As described previously, the City is primarily built out and any housing constructed within the City limits would most likely be infill housing. Therefore, DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 15-4 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT the OPSP could result in an increased unfavorable jobs/housing ratio in the City which would increase over the implementation of the Phase I Project and subsequent phases of the OPSP. A jobs-housing ratio is a numeric representation of the relationship between the total number of jobs and the total number of residential units in an area. This ratio indicates the ability of a region to provide both adequate employment and housing opportunities for its existing and projected population. A jobs housing ratio of 1.0 represents a balance of jobs and housing. An overall jobs-housing ratio of 1.0 to 1.5 is generally considered balanced (so that there is little in- or out-commuting). A balance of jobs and housing can benefit the regional environment by reducing commute times and distances between residential areas and employment centers. Longer commutes result in increased vehicle trip length, which creates environmental effects, such as those associated with transportation, air quality, and noise. As discussed in the setting above, South San Francisco currently has a high jobs/housing ratio of 1.7; this means that South San Francisco is a job center that imports employees from surrounding communities, or alternatively, that exports housing. Based on ABAG’s projections, the future jobs/housing ratio in the City for 2015 would increase to approximately 2.09 by 2015 and to 2.11 by 2020. These ratios suggest poor housing availability relative to the amount of jobs projected, and a high level of in-commuting. Housing availability, already projected to be out of balance, would decrease with implementation of the Phase I Project and subsequent phases of the OPSP. Assuming that not more than one person per household would be employed by the OPSP, the OPSP would add 1,646 employees with Phase I and 5,717 more by build out of the OPSP. This would create the need for 8,488 new units of housing, which can not all be provided for within South San Francisco city limits. Consequently, the potential employment increase resulting from the OPSP would result in indirect growth that may not be accommodated by existing or proposed housing projections for the City. However, continued job growth in the City will promote a greater regional balance between jobs and housing. The City is a strategically located inner Bay Area community well served by all modes of transit—including air and rail, BART, and on a site that will soon be hosting ferry service as well. Therefore, future employees commuting to jobs in the City would have varied means of reaching the project. Given the fact that the City does not have an adopted jobs/housing ratio goal, and overall the OPSP would promote a greater regional jobs balance, the impact of the Phase I Project and OPSP on indirect population growth would be less than significant and no mitigation measures are required. PUBLIC SERVICES SETTING Police Service Police service within the OPSP area is provided by the South San Francisco Police Department (SSFPD). The SSFPD has an agreement with the San Mateo County Harbor District for radio communication and emergency response coordination. The South San Francisco Police Department’s jurisdictional area includes the entire city. The Department currently has a total of 79 sworn officers and 35 civilian employees covering a city of approximately 60,000 residents with a daytime population around 100,000 people.1 That’s a ratio of approximately 1.3 sworn officers for every one thousand 1 City of South San Francisco website, http://www.ci.ssf.ca.us/index.aspx?NID=285. Accessed 9/23/2010. CHAPTER 15: POPULATION, PUBLIC SERVICES AND RECREATION OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 15-5 residents. The Department is generally able to respond to high priority calls within two to three minutes. These times are within the Department’s response time goals. The Department typically works a four-beat system, but the watch supervisor has the discretion to deploy his personnel as he sees fit to accomplish daily goals and objectives. Each beat is typically staffed by a one officer unit with between six and nine other officers consisting of traffic, K-9, training, float, and supervisory units available for backup and overlap. The South San Francisco General Plan establishes guiding policies 8.5-G1 to 8.5-G2 to provide police services that are responsive to citizen’s needs to ensure a safe and secure environment for people and property in the community and to assist in crime prevention through physical planning and community design. Fire Service Fire protection and emergency services within the OPSP area is the responsibility of the South San Francisco Fire Department (SSFFD). The SSFFD has 85 members. Minimum on-duty staffing is 20 persons. There are currently five fire stations located throughout South San Francisco. In addition to the paramedics, the rest of the fire personnel are certified Emergency Medical Technicians (EMT). The SSFFD also has Advanced Life Support (ALS) engines that arrive on scene with a paramedic aboard. Station #62 is the closest station to the OPSP site, less then one mile away at 249 Harbor Way. Schools The City of South San Francisco is served by the South San Francisco Unified School District. The South San Francisco Unified School District includes ten elementary schools for kindergarten through 5th grade, three middle schools for grades 6 through 8 and three high schools for grades 9 through 12 as well as an adult education program. PUBLIC SERVICES IMPACT ANALYSIS Standards of Significance Under the CEQA Guidelines, Appendix G – Environmental Checklist Form, development of the OPSP site as proposed would have a significant environmental impact if it were to result in: 1.Substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for any of the public services: x fire services x police services x schools x parks x other public facilities DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 15-6 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Police Services Implementation of the proposed OPSP would increase development within the OPSP area, which would translate to an increase in workers on the site, specifically a net increase in 1,646 employees working on the site by the end of the Phase I Project and 5,717 additional by build-out of the OPSP, as discussed in more detail under Population, above. Compared to a daytime population of 100,000, this would represent minor increases in the City’s daytime population (1.6% for the Phase I Project and 5.7% for the OPSP) and would not lead to a change in response times and/or requirement for construction of new facilities. The SSFPD is generally able to respond to high priority calls within two to three minutes time and average response times are five to seven minutes depending on the priority. These times are within the department’s response time goals. With implementation of the proposed OPSP, police surveillance at the OPSP site would continue adequately with routine patrols and responses to calls for assistance. As implementation of the proposed OPSP, including the Phase I Project, would constitute a negligible increase in the City’s population, and would not result in SSFPD’s inability to maintain acceptable service ratios, response times, or other performance objectives or meet the goals of the General Plan. Current response times and service ratios are adequate and no new facilities that would result in potential significant impacts would be required. Therefore, the impact would be less than significant and no mitigation measures are required. Fire Services Station #62 is the closest station to the OPSP site, less then one mile away at 249 Harbor Way, and would provide all first response services to the OPSP. Build-out of the OPSP would not be anticipated to result in SSFPD’s inability to maintain acceptable service ratios, response times, or other performance objectives. Current response times and service ratios are adequate and no new facilities that would result in potential significant impacts would be required. The OPSP site is not located in any of the city’s fire hazard management unit areas. The OPSP’s design would be required to comply with the City’s Fire Code (Chapter 15.24 of the Municipal Code) and the City Fire Marshall’s code requirements regarding on site access for emergency vehicles as is a standard condition for any project approval. Therefore, the OPSP would have a less than significant impact on the city’s fire protection services. Schools It is possible that some users of the OPSP site would relocate to the City, thereby generating a small student population increase in the South San Francisco Unified School District. However, because the OPSP would not involve construction of new residences, it is not expected that the school district would experience a significant growth in student population. Therefore, the impact on the South San Francisco Unified School District would be less than significant. Other The potential impacts related to parks are discussed under recreation, below. No impacts to other public services are anticipated. CHAPTER 15: POPULATION, PUBLIC SERVICES AND RECREATION OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 15-7 RECREATION SETTING The City of South San Francisco Parks and Recreation Department manages parks and recreation centers within the city boundaries. According to the Parks, Recreation, and Open Space element of the South San Francisco General Plan, there is an estimated 320 acres of parks and open space in the city, including community parks, neighborhood parks, mini-parks, linear parks, open spaces and school lands. RECREATION IMPACT ANALYSIS Standards of Significance Under the CEQA Guidelines, Appendix G – Environmental Checklist Form, development of the OPSP site as proposed would have a significant environmental impact if it were to result in: 1.Increased use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated; or 2.Substantial adverse physical impacts associated with the provision of new or physically altered recreation facilities, or the need for new or physically altered recreation facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios. The South San Francisco General Plan requires 0.5 acres of parks per 1,000 new employees in employment areas or payment of in-lieu fees. Using the estimate of 5,965 net new on-site employment discussed above, 2.98 acres of parks or appropriate in lieu fees would be required. The proposed OPSP includes an approximately 3-acre flexible-use recreation area (park) and an additional approximately 3.1 acres of bay front open space, which is more than the projected need generated by employees of the site. Thus the OPSP would have not only a less-than-significant impact on existing facilities, but a net beneficial impact on recreational facilities.

Excerpts and findings from the following EIRs or initial studies/negative declarations have been included in this chapter: Genentech Master Plan Revised Draft EIR (EIP Associates and Korve Engineering, as partially revised December 2006), 213 East Grand Avenue Draft EIR (Lamphier-Gregory and Crane Transportation Group, December 2007), 328 Roebling Road Draft EIR (Lamphier-Gregory and Crane Transportation Group, April 2008), 494 Forbes Draft Focused EIR (Impact Sciences and Crane Transportation Group, October 2009) and the Gateway Business Park Master Plan Draft and Final EIRs (Christopher Joseph Associates and Crane Transportation Group, March 2010). SETTING ROADWAYS The OPSP site is located at the west end of Oyster Point Boulevard and along Marina Boulevard. At the Oyster Point Boulevard / Marina Boulevard T-intersection, Oyster Point continues north to existing development, and Marina Boulevard goes south/east toward the Ferry Terminal (currently under construction), Oyster Point Park and the Oyster Point Marina (see Figures 3.1 through 3.4). OPSP access to the U.S. 101 freeway is provided by a variety of major streets with several route options available to the three interchanges that could potentially be used by OPSP traffic. Each is briefly described below, while a schematic presentation of existing intersection approach lanes and control are presented in Figure 16.1. Freeways U.S.101 is an eight-lane freeway that provides access to the OPSP area. It extends from downtown San Francisco and northern California to Los Angeles and southern California. Within the study area, U.S.101 has northbound on-ramps at South Airport Boulevard (at Wondercolor Lane between Mitchell Avenue and Utah Avenue), at Grand Avenue and at Oyster Point Boulevard; northbound off-ramps are provided at, South Airport Boulevard (at Wondercolor Lane between Mitchell Avenue and Utah Avenue), at East Grand Avenue / Executive Drive and at Dubuque Avenue (just south of Oyster Point Boulevard). Southbound on-ramps are provided from Airport Boulevard (north of Oyster Point Boulevard), Dubuque Avenue (just south of Oyster Point Boulevard), and at Produce Avenue; southbound off-ramps are provided at Airport Boulevard (just north of Oyster Point Boulevard), Oyster Point Boulevard / Gateway Boulevard and at Produce Avenue. There are auxiliary lanes on northbound U.S.101 both north and south of Oyster Point Boulevard and on southbound U.S.101 south of Oyster Point Boulevard. In 2008 U.S.101 carried an annual average daily traffic (ADT) volume of 203,000 vehicles south of Produce Avenue, 203,000 vehicles south of Oyster Point Boulevard and 194,000 vehicles just north of Oyster Point Boulevard.1 1 Traffic Volumes on California State Highways, Caltrans 2008. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 16-2 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Oyster Point Boulevard is one of the primary arterial access routes serving the “East of 101 area” in South San Francisco. It has six travel lanes near its interchange with the U.S.101 freeway, four lanes east of Veterans Boulevard and two lanes near Gull Road and farther to the east (and north) internal to the OPSP site. East Grand Avenue is a major arterial street and a central access route serving the industrial/ office areas east of the U.S.101 freeway. It has six travel lanes in the vicinity of the freeway and narrows to four travel lanes east of the Forbes Boulevard / Harbor Way intersection. Harbor Way is a two-lane street serving existing and planned industrial/office uses south of East Grand Avenue. Harbor Way provides access to South Airport Boulevard and several U.S.101 freeway ramps via Mitchell Avenue and Utah Avenue. Forbes Boulevard is a four-lane collector street connecting the San Bruno Point Genentech area with East Grand Avenue. In the OPSP vicinity it is 60 feet wide curb to curb with an intermittent raised median that is 12 feet wide. On-street parking is prohibited. Airport Boulevard is a four- to six-lane, north-south arterial street that parallels the west side of the U.S.101 freeway. This roadway continues north into the City of Brisbane and the City of San Francisco, where it is called Bayshore Boulevard. South of San Mateo Avenue, Airport Boulevard changes names to Produce Avenue. In the General Plan, Airport Boulevard is classified as a major arterial. Marina Boulevard is a two-lane collector street extending easterly from Oyster Point Boulevard and ending at the east end of Oyster Point Park and Oyster Point Marina. It primarily serves as access to parking areas for the Marina and the Park. Gateway Boulevard is a four-lane major arterial street connecting East Grand Avenue with South Airport Boulevard and Oyster Point Boulevard. Littlefield Avenue is a 40-foot-wide, two-lane north-south street connecting East Grand Avenue with Utah Avenue. Utah Avenue is a four-lane east-west street connecting Littlefield Avenue with South Airport Boulevard. South Airport Boulevard is a four-lane divided roadway traveling from the Airport Boulevard / San Mateo Avenue / Produce Avenue intersection on the north near U.S.101 to the San Bruno Avenue East / North McDonnell Road intersection on the south. Most of South Airport Boulevard runs parallel to and east of U.S.101. Dubuque Avenue is a two- to four-lane roadway running east of and almost parallel to U.S.101 in a north/south direction. Extending from East Grand Avenue to Oyster Point Boulevard this roadway functions as a connector street for the traffic traveling primarily between U.S.101 and Oyster Point Boulevard. Mitchell Avenue is a two-lane roadway running in an east/west direction. Mitchell Avenue connects Airport Boulevard / Gateway Boulevard on the west to Harbor Way on the east.

INTERSECTION OPERATION Analysis Methodology Signalized Intersections. Intersections, rather than roadway segments between intersections, are almost always the capacity controlling locations for any circulation system. Signalized intersection operation is graded based upon two different scales. The first scale employs a grading system called Level of Service (LOS) which ranges from Level A, indicating uncongested flow and minimum delay to drivers, down to Level F, indicating significant congestion and delay on most or all intersection approaches. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 16-6 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT The Level of Service scale is also associated with a control delay tabulation (year 2000 Transportation Research Board [TRB] Highway Capacity Manual [HCM] operations method) at each intersection. The control delay designation allows a more detailed examination of the impacts of a particular project. Greater detail regarding the LOS/control delay relationship is provided in Table 16.1. Table 16.1: Signalized Intersection LOS Criteria Level of Service Description Average Control Delay (Seconds Per Vehicle) A Operations with very low delay occurring with favorable progression and/or short cycle lengths. ” 10.0 B Operations with low delay occurring with good progression and/or short cycle lengths. 10.1 to 20.0 C Operations with average delays resulting from fair progression and/or longer cycle lengths. Individual cycle failures begin to appear. 20.1 to 35.0 D Operations with longer delays due to a combination of unfavorable progression, long cycle lengths, and/or high volume-to-capacity (V/C) ratios. Many vehicles stop and individual cycle failures are noticeable. 35.1 to 55.0 E Operations with high delay values indicating poor progression, long cycle lengths, and high V/C ratios. Individual cycle failures are frequent occurrences. This is considered to be the limit of acceptable delay. 55.1 to 80.0 F Operation with delays unacceptable to most drivers occurring due to oversaturation, poor progression, or very long cycle lengths. > 80.0 Source: 2000 Highway Capacity Manual (Transportation Research Board). Unsignalized Intersections. Unsignalized intersection operation is also typically graded using the Level of Service A through F scale. LOS ratings for all-way stop intersections are determined using a methodology outlined in the year 2000 TRB Highway Capacity Manual. Under this methodology, all- way stop intersections receive one LOS designation reflecting operation of the entire intersection. Average control delay values are also calculated. Intersections with side streets only stop sign controlled (two-way stop control) are also evaluated using the LOS and average control delay scales using a methodology outlined in the year 2000 TRB Highway Capacity Manual. However, unlike signalized or all-way stop analysis where the LOS and control delay designations only pertain to the entire intersection, in side street stop sign control analysis LOS and delay designations are computed for only the stop sign controlled approaches or individual turn and through movements. Table 16.2 provides greater detail about unsignalized analysis methodologies. Table 16.2: Unsignalized Intersection LOS Criteria Level of Service Description Average Control Delay (Seconds Per Vehicle) A Little or no delays ” 10.0 B Short traffic delays 10.1 to 15.0 C Average traffic delays 15.1 to 25.0 D Long traffic delays 25.1 to 35.0 E Very long traffic delays 35.1 to 50.0 F Extreme traffic delays with intersection capacity exceeded (for an all-way stop), or with approach/turn movement capacity exceeded (for a side street stop controlled intersection) > 50.0 Source: 2000 Highway Capacity Manual (Transportation Research Board). CHAPTER 16: TRANSPORTATION AND CIRCULATION OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 16-7 Analysis Software All existing and future operating conditions have been evaluated using the Synchro software program. Standards The City of South San Francisco considers Level of Service D (LOS D) to be the poorest acceptable operation for signalized and all-way-stop intersections, with LOS E the poorest acceptable operation for unsignalized city street intersection turn movements. Existing Intersection Operating Conditions Table 16.3 shows that all 22 existing analyzed intersections are currently operating at good to acceptable (LOS D or better) Levels of Service during both the AM and PM peak traffic hours. VEHICLE QUEUING Analysis Methodology The Synchro software program has determined projections of vehicle queuing on the critical approaches to five signalized off-ramp intersections evaluated in this study and on the approaches to adjacent intersections that need to accommodate flow from the off-ramp intersection: x U.S.101 Southbound Off-Ramp / Airport Boulevard / Miller Avenue intersection & the adjacent Airport Boulevard / Grand Avenue intersection x U.S.101 Northbound Off-Ramp / South Airport Boulevard / Wondercolor Lane intersection x U.S.101 Southbound Flyover Off-Ramp / Oyster Point Boulevard / Gateway Boulevard intersection x U.S.101 Northbound Off-Ramp / Dubuque Avenue intersection & the adjacent Oyster Point Boulevard / Dubuque Avenue / U.S.101 Northbound On-Ramp intersection x U.S.101 Southbound Off-Ramp / Airport Boulevard intersection In addition, off-ramp queuing was also evaluated on the U.S.101 Northbound Off-Ramp connection to East Grand Avenue / Executive Drive. While this off-ramp is not controlled on its approach to this first intersection, East Grand Avenue is signal controlled at its next major intersection to the east (at Grand Avenue Overcrossing). Queuing results for this signalized location were evaluated to see if any queuing extended back to the off-ramp. Projections are provided for each off-ramp as well as for turn lanes and other surface street approaches that have nearby adjacent intersections. Queuing Standards The standard adopted by the City of South San Francisco and Caltrans is that the 95th percentile vehicle queue must be accommodated within available storage for each off-ramp and on the approaches to intersections adjacent to off-ramp intersections that accommodate a significant amount of off-ramp traffic. In addition, no off-ramp traffic is allowed to back up to the freeway mainline during the entire AM or PM peak traffic hour. The 95th percentile queue indicates that vehicle backups will only extend beyond this length five percent of the time during the analysis hour. Queuing analysis is presented in this study for year 2015 and 2035 Base Case and Base Case + Project conditions. Off-ramp queuing has been evaluated using both the Synchro software output, which details queuing for one of the signal cycles during the peak traffic hour, as well as using the SIM traffic feature of the Synchro program, which evaluates off-ramp operation and backups during the entire peak traffic hour.

Year 2000 Highway Capacity Manual Analysis Methodology Source: Crane Transportation Group CHAPTER 16: TRANSPORTATION AND CIRCULATION OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 16-9 FREEWAY OPERATION Analysis Methodology U.S.101 freeway segments have been evaluated based on the Year 2000 Highway Capacity Manual as specified by Caltrans and the San Mateo County Congestion Management Program (CMP). U.S.101 existing traffic conditions have been evaluated for the weekday AM and PM peak hours. Existing traffic volumes used for the analysis were derived from year 2009 U.S.101 mainline counts from Caltrans as provided by TJKM Associates as part of their work for the updating of the City’s East of 101 Traffic Modeling. Freeway mainline analysis was performed using the HCS software based upon the HCM methodology for freeway mainlines. San Mateo CMP Standards for Regional Roads and Local Streets The LOS standards established for roads and intersections in the San Mateo County CMP street network vary based on geographic differences. For roadway segments and intersections near the county boarder, the LOS standard was set as LOS E in order to be consistent with the recommendations in the neighboring counties. If the existing Level of Service in 1990/91 was F, the standard was set to LOS F. If the existing or future LOS was or will be E, the standard was set to E. For the remaining roadways and intersections, the standard was set to be one letter designation worse than the projected LOS in the year 2000. If a proposed land use change would either cause a deficiency (to operate below the standard LOS) on a CMP-designated roadway system facility, or would significantly affect (by using LOS F in the 1991 CMP baseline LOS, mitigation measures are to be developed so that LOS standards are maintained on the CMP-designated roadway system. If mitigation measures are not feasible (due to financial, environmental or other factors), a Deficiency Plan must be prepared for the deficient facility. The Deficiency Plan must indicate the land use and infrastructure action items to be implemented by the local agency to eliminate the deficient conditions. A Deficiency Plan may not be required if the deficiency would not occur if traffic originating outside the County were excluded from the determination of conformance. Existing Freeway Operation Existing Levels of Service on the freeway segments in South San Francisco were based upon analysis of year 2009 volumes. Table 16.4 shows a summary of existing U.S. 101 freeway operation and Table 16.5 shows details of the existing freeway Level of Service results. Currently, all U.S.101 freeway segments are operating at an acceptable LOS D or better during the weekday AM and PM peak hours. Conditions are generally poorer along U.S.101 to the north of Oyster Point Boulevard, and peak in both the northbound and the southbound directions during the AM peak hour and in the northbound direction during the PM peak hour.

However, currently there is no SamTrans service east of the U.S.101 freeway. Bus service running just west of the freeway is as follows. Route 34: Tanforan Shopping Center–Geneva operates along Bayshore Boulevard and Airport Boulevard between Brisbane and the San Bruno BART station in the study area. This route operates during midday only on weekdays with headways of about two hours. Route 130: Daly City/Colma BART–South San Francisco operates along Linden Avenue and Grand Avenue in the study area. It connects central South San Francisco with the Colma BART station and Daly City. It operates with 20-minute peak period headways and 30- to 60-minute non-peak headways on weekdays, 30-minute headways on Saturdays and 60-minute headways on Sundays. Route 132: Airport/Linden-Arroyo/El Camino operates along Hillside Avenue and Grand Avenue connecting to the South San Francisco BART station. It operates on 30-minute peak period headways and 60-minute non-peak headways on weekdays and 60-minute headways on Saturdays. Route 292: San Francisco–SF Airport–Hillsdale Shopping Center operates along Airport Boulevard. It operates with 20- to 30-minute peak headways and 25- to 60-minute non-peak headways on weekdays and 30- to 60- minute headways on Saturdays and Sundays. Caltrain Caltrain provides train service between Gilroy, San Jose and San Francisco. There is a station located on the corner of Dubuque Avenue and Grand Avenue Overcrossing in South San Francisco. Trains operate every 15 to 20 minutes during commute periods and hourly during midday. Caltrain/BART Shuttles Van shuttles are provided between the South San Francisco Caltrain station and employment centers east of U.S.101 during commute hours. Separate shuttles provide service to/from the Colma BART station. Shuttle stops are provided at two locations along East Grand Avenue and at one location along Harbor Way adjacent to the OPSP site. CHAPTER 16: TRANSPORTATION AND CIRCULATION OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 16-15 The Gateway Area/Genentech Shuttle (BART and Caltrain) provides service on Gateway Boulevard, Oyster Point Boulevard, Forbes Boulevard, Grandview Drive and East Grand Avenue. There are 15 morning trips and 15 afternoon trips on the BART shuttle, and six morning trips and five afternoon trips on the Caltrain shuttle. The Utah-Grand Shuttle (BART and Caltrain) serves over 20 employers in the Utah/Grand/Littlefield area. It provides service on Harbor Way, East Grand Avenue, Cabot Court, Grandview Avenue, Littlefield Avenue, Haskin Way and Utah Avenue. There are nine trips in the morning and nine trips in the afternoon on the BART shuttle, with nine morning and eight afternoon trips on the Caltrain shuttle. All shuttle service is fixed-route, fixed-schedule and is provided on weekdays during the commute periods. The shuttles are free to riders. The operating costs are borne by the Joint Powers Board (JPB), SamTrans, the Bay Area Air Quality Management District, and the City/County Association of Governments (75 percent) and sponsoring employers (25 percent). PEDESTRIAN AND BICYCLE FACILITIES Sidewalks are in place along Oyster Point Boulevard in the OPSP vicinity. There are no sidewalks along Marina Boulevard. However, there are paved pathways in Oyster Point Park adjacent to Marina Boulevard. There are no Class II or Class III bicycle lane designations along Oyster Point Boulevard or Marina Boulevard internal to the OPSP site, although there are numerous bicycle facilities available in the study area. Bike lanes are provided along East Grand Avenue east of Littlefield Avenue, Sister Cities Boulevard, Oyster Point Boulevard (east of Gateway Avenue), Gull Road, and Gateway Boulevard (south of East Grand Avenue). Bike routes are designated on South Airport Boulevard and on East Grand Avenue between Executive Drive and the East Grand Overcrossing. Bike paths are available along Executive Drive, and along the shoreline. Future bike lanes are planned along Gateway Boulevard, East Grand Avenue, Allerton Avenue, and Forbes Boulevard (east of Allerton Avenue). Future bike routes are planned along Forbes Boulevard (west of Allerton Avenue), while a future bike path is planned along the Caltrain right-of-way. The proposed future bike lanes, routes, and paths are designated in the General Plan Transportation Element. CITY OF SOUTH SAN FRANCISCO TRANSPORTATION DEMAND MANAGEMENT PROGRAM The City of South San Francisco requires that all nonresidential development expected to generate 100 or more average daily trips, based on the Institute of Traffic Engineers (ITE) trip generation rates or a project seeking a floor area ratio (FAR) bonus implement Transportation Demand Management (TDM) measures to reduce vehicle traffic (Chapter 20.120 Transportation Demand Management). The purposes of the TDM ordinance are as follows: x Implement a program designed to reduce the amount of traffic generated by new nonresidential development, and the expansion of existing nonresidential development pursuant to the City’s police power and necessary in order to protect the public health, safety and welfare. x Ensure that expected increases in traffic resulting from growth in employment opportunities in the City of South San Francisco will be adequately mitigated. x Reduce drive-alone commute trips during peak traffic periods by using a combination of services, incentives, and facilities. x Promote the more efficient utilization of existing transportation facilities and ensure that new developments are designed in ways to maximize the potential for alternative transportation usage. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 16-16 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT x Establish minimum TDM requirements for all new nonresidential development. x Allow reduced parking requirements for projects implementing the requirements of this chapter. x Establish an ongoing monitoring and enforcement program to ensure that the measures are implemented. The analysis prepared for the General Plan Amendment includes the assumption that a moderate TDM program will reduce peak hour traffic generation by an additional 9.5 percent compared to existing traffic generation rates, while an intensive TDM program will reduce peak hour traffic generation by an additional 20 to 25 percent. The objective of TDM programs is to reduce vehicle trips at commercial/residential developments by incorporating project components such as encouraging increased transit use, carpooling, and providing facilities for bicyclists and pedestrians. South San Francisco has a “menu” of potential TDM programs, each with a specific number of points that relate to the program’s effectiveness. Examples of TDM programs include bicycle racks and lockers, free carpool parking, shuttle services, and on-site amenities. FUTURE BASE CASE (WITHOUT PROJECT) CONDITIONS The traffic impacts have been evaluated in relation to both year 2015 and year 2035 Base Case conditions. Year 2015 reflects a horizon year that the Phase I Project of the OPSP should be completed, while year 2035 reflects the most distant horizon year currently utilized by the City Public Works Department and Caltrans for analysis purposes and the assumed build out of the OPSP and East of 101 area. This section details the process to determine Base Case traffic operation for year 2015 and 2035 conditions. Year 2015 Base Case Development The year 2015 Base Case conditions include traffic generated by existing, approved and proposed development in the study area, as well as traffic generated by projects that are under construction. The development list was provided by City Planning staff. Projects and their associated trip generation are provided in the Table 16.10 and have been utilized by TJKM Associates to develop local area intersection and freeway volumes for use in the City’s updated East of 101 Transportation Capital Improvement Program study. Year 2015 peak hour Base Case (without project) conditions were developed by adding traffic expected to be generated by all the approved and proposed developments in the greater East of 101 Area to the existing traffic network. Year 2015 projections include traffic from several recently approved background projects such as Gateway Business Park, 213 E. Grand, Lowe’s, Home Depot, Terrabay, the ferry terminal that is currently under construction and the Genentech Corporate Facilities Master Plan, as well as traffic from the proposed 494 Forbes and 328 Roebling Road developments.

In accordance with the Mitigation Fee Act, impact fees are imposed on and collected from development projects in the East of 101 area, held in a separate account, and used to fund improvements benefiting the area and the projects from which the fees were collected. Like other projects in the East of 101 area, the projects developed under the OPSP, including the Phase I Project, will pay a proportionate share towards these improvements. The City is in the process of updating their capital improvement program list for the East of 101 area; a new list is expected to be available in mid 2011. Based on currently available funding, projected growth rates, and the pending update, the City of South San Francisco Public Works division expects that the following intersection improvements will be funded and constructed by 2015. Accordingly, the improvements have been factored into the year 2015 Base Case traffic modeling conducted by TJKM Associates for the 2010 Updated East of 101 Capital Improvement Program. x S.

Year 2000 Highway Capacity Manual Analysis Methodology Source: Crane Transportation Group YEAR 2035 BASE CASE OPERATING CONDITIONS The year 2035 Base Case conditions include traffic generated by all development detailed in the 2015 analysis, the last half of the Genentech master plan the remaining half of the Gateway Master Plan as well as other increases in manufacturing, commercial, office and R&D uses. The daily and peak hour trip generation potential of all developments expected in the East of 101 area by 2035 is presented in Table 16.14. In addition to these specific developments, traffic on Airport Boulevard to/from Brisbane to the north as well as on Sister Cities Boulevard and other surface streets to the west of the U.S. 101 freeway were projected to grow from 2016 to 2035 at rates projected in the C/CAG regional model (after allowance for traffic to/from new development east of the 101 freeway). The net increase in local area trip generation between 2016 and 2035 is presented in Table 16.15. Year 2035 intersection AM and PM peak hour as well as U.S.101 freeway segment traffic volumes were developed by TJKM Associates for the City’s Update of the East of 101 Capital Improvements Program. Year 2035 Base Case (without project) AM and PM peak hour intersection volumes are presented in Figures 9 and 10 in Appendix E.

Year 2000 Highway Capacity Manual Analysis Methodology Source: Crane Transportation Group IMPACTS AND MITIGATION MEASURES SIGNIFICANCE CRITERIA Standards of Significance have been measured based on CEQA, City of South San Francisco and C/CAG Guideline thresholds. Therefore, project impacts would be significant if they result in any of the following conditions: a.The project would exceed 100 net new peak hour trips on the local roadway system (C/CAG criteria only). b.Signalized intersection operation and all-way-stop operation would change from Level of Service (LOS) A, B, C or D to LOS E or F and total volumes passing through the intersection would be increased by at least two percent. c.Uncontrolled turn movements or stop sign controlled approaches at side street stop sign controlled intersections would change from LOS A, B, C, D or E to LOS F and total volumes passing through CHAPTER 16: TRANSPORTATION AND CIRCULATION OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 16-31 the intersection would be increased by at least two percent. Side street criteria are applicable only for stop sign controlled approaches with more than 25 trips during any peak traffic hour. d.The proposed project would increase total volumes passing through an intersection by two percent or more with signalized or all-way stop operation already at a Base Case LOS E or F, or when the intersection is side street stop sign controlled and the stop sign controlled Base Case operation is at LOS F (and there are more than 25 vehicles on the stop sign controlled approach). e.Project traffic would increase Base Case volumes at an unsignalized intersection to meet peak hour volume signal warrant criteria levels, or to meet pedestrian/school crossing signal warrant criteria levels. f.The proposed project would increase traffic entering an unsignalized intersection by two percent or more with Base Case traffic levels already exceeding peak hour volume signal warrant criteria levels. g.Project traffic would increase acceptable Base Case 95th percentile vehicle queuing on a freeway off-ramp and/or also on the approaches to adjacent intersections leading away from off-ramp intersections to unacceptable levels (as determined by the Synchro software program), or if Base Case 95th percentile queuing on the freeway off-ramps or on the approaches to adjacent intersections leading away from off-ramp intersections is already projected at unacceptable lengths, the project would increase queuing volumes by one percent or more. h.Project traffic results in queues exceeding off-ramp storage capacity based upon SIM traffic software evaluation. If base case traffic already exceeds the storage capacity of the off-ramp, then a one-percent addition in traffic due to the project is considered a significant impact. i.Project traffic would degrade operation of the U.S. 101 freeway or freeway ramps from LOS E to LOS F with at least a one percent increase in volume, or would increase volumes by more than one percent on a freeway segment or a freeway ramp with Base Case LOS F operation. j.If on-site circulation would be confusing to drivers and result in excessive traffic flow through various parts of the project site. k.Project development or project traffic would produce a detrimental impact to local transit or shuttle service. l.If, in the opinion of the registered traffic engineer conducting the EIR analysis, a significant traffic, pedestrian or bicycle safety concern would be created or worsened. TRIP GENERATION Table 16.19 shows that by 2015 the Phase I Project would generate 369 inbound and 48 outbound net new trips during the AM peak hour, with 55 inbound and 343 outbound net new trips during the PM peak hour. This assumes a 20.0 percent reduction in peak hour trips due to a vigorous City-mandated TDM program. By 2035, total net new trip generation after OPSP completion would be 1,158 inbound and 244 outbound trips during the AM peak hour, with 426 inbound and 1,195 outbound trips during the PM peak hour. The 2035 analysis assumes a 25 percent reduction in peak hour trips due to a vigorous City-mandated TDM program.

It is likely that OPSP drivers destined to/from the U.S.101 freeway either north or south would choose to access the freeway via several routes and interchanges.

CHAPTER 16: TRANSPORTATION AND CIRCULATION OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 16-33 Impact Traf-1: Trip Generation Exceeds 100 Trips During Peak Hours. Both the Phase I Project and the entire OPSP would generate more than 100 net new two-way trips during the AM and PM peak hours (1,402 trips during the AM peak hour and 1,621 trips during the PM peak hour at build out of the OPSP, as shown in Table 16.19). The San Mateo City/County Association of Governments (C/CAG) Agency Guidelines for the implementation of the 2003 Draft Congestion Management Program (“C/CAG Guidelines”) specifies that local jurisdictions must ensure that the developer and/or tenants will mitigate all new peak hour trips (including the first 100 trips) projected to be generated by the development. This would be a significant impact. Mitigation Measure Traf-1: Transportation Demand Management Program. The OPSP sponsors shall implement a Transportation Demand Management (TDM) program consistent with the City of South San Francisco Zoning Ordinance Chapter 20.400 Transportation Demand Management, and acceptable to C/CAG. These programs, once implemented, must be ongoing for the occupied life of the development. The C/CAG guidelines specify the number of trips that may be credited for each TDM measure. Impact reduced to a less-than-significant level. PEDESTRIAN FACILITIES Impact Traf-2: Pedestrian Walkways. Sidewalks will be provided along both sides of Oyster Point Boulevard and Marina Boulevard internal to the OPSP site. Sidewalks will also be provided along both sides of all other internal roadways connecting to Marina Boulevard. The Phase I TDM Conceptual Site Plan (June 1, 2010) shows pedestrian connections between OPSP buildings and the sidewalks lining Oyster Point Boulevard and Marina Boulevard. No such detail has been provided by the applicant for the other phases of development. No detail has been provided regarding pedestrian access to the Phases III & IV garage and whether midblock pedestrian access points are proposed that could encourage midblock crossing. These would be potentially significant impacts. Mitigation Measure Traf-2: Pedestrian Facilities. To discourage mid-block crossing,pedestrian flow across Oyster Point Boulevard between the Phase III & IV garage and the Phase III & IV offices shall be regulated to the following extent. Pedestrian access shall only be allowed at the north and south ends of the garage, adjacent to signalized or all-way stop intersections. Impacts reduced to a less-than-significant level. BICYCLE FACILITIES Impact Traf-3: Bicycle Lane. Class II bicycle lanes will be provided along Oyster Point Boulevard and Marina Boulevard their entire lengths internal to the OPSP site. The DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 16-34 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Bay Trail bike/pedestrian path will also be completed internal to the OPSP site. The Phase I TDM conceptual site plan shows that bike parking areas will be provided within the building’s garage. These would be a less-than-significant impact, therefore no mitigation is required. INTERNAL CIRCULATION Impact Traf-4: Year 2015 Internal Circulation. Year 2015 Base Case + Phase I Project and AM and PM peak hour volumes and roadway geometrics expected internal to the project site along Oyster Point Boulevard and Marina Boulevard (with Phase I development) are presented in Figure 16 in Appendix E. Analysis has been conducted of the Oyster Point Boulevard / Marina Boulevard and Marina Boulevard / Phase I access/Bayfront parking lot intersections assuming all-way stop control at each intersection. As shown in Table 16.21 below, both intersections should operate acceptably with projected year 2015 volumes, including development of the Phase I Project.

Impact Traf-5: Year 2035 Internal Circulation. Year 2035 Base Case + OPSP AM and PM peak hour volumes expected internal to the OPSP site along Oyster Point Boulevard and Marina Boulevard (with full OPSP development) are presented in Appendix E, Figure 21, while projected roadway geometrics and control are presented in Appendix E Figure 22. Operations analysis has been conducted for the Oyster Point Boulevard / Marina Boulevard, Marina Boulevard / Phase I access / Bayfront parking lot, Oyster Point Boulevard / Phase II garage / Phases III / IV garage and Oyster Point Boulevard / North Access intersections. The north intersection includes an easterly extension of Oyster Point Boulevard to serve a secondary access to the OPSP Phases III / IV garage as well as traffic from two existing office buildings to the east of the OPSP. The western leg of the north access intersection will provide access to the Oyster Cove Marina to the west of the OPSP. Based upon an iterative analysis process, it was determined that all-way stop control would only provide acceptable operation at the Marina Boulevard / Phase I and Oyster Point Boulevard / North Access intersections. Signalization would be required at the other two locations. At City request, two access options were evaluated for the OPSP Phases III / IV garage to the east of Oyster Point Boulevard. Each is described below. CHAPTER 16: TRANSPORTATION AND CIRCULATION OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 16-35 Phase III/IV Parking Garage Access Option 1 Phases III / IV garage access will be provided as a fourth (easterly) leg of the Oyster Point / Phase II garage access intersection: Outbound flow only will be provided from the Phases III / IV garage. Primary inbound access to the Phases III / IV garage will be provided to Oyster Point Boulevard just to the north of the signalized Oyster Point Boulevard / Phase II garage / Phases III / IV garage exit intersection. Secondary inbound / outbound access to the Phases III / IV garage will be provided from Oyster Point Boulevard running along the north side of the garage. Phase III/IV Parking Garage Access Option 2 Phases III / IV garage access will be provided as a fourth (easterly) leg of the Oyster Point / Phase II garage access intersection. Both inbound and outbound flow will be provided for the Phases III / IV garage. Inbound flow to the Phases III / IV garage just north of this intersection will be eliminated. Secondary inbound / outbound access to the Phases III / IV garage will be provided from Oyster Point Boulevard running along the north side of the garage. Operating results are presented below in Tables 13.22a and b for the two access options.

Failure of the applicant to provide required signalization would result in less than acceptable operation. This would be a significant impact. Mitigation Measure Traf-5: Internal Circulation System Signalization. The OPSP applicant shall provide signals at the Oyster Point Boulevard / Marina Boulevard and Oyster Point Boulevard / Phase II Access / Phases III / IV garage access intersections when volumes are approaching warrant criteria levels. Impact reduced to a less-than-significant level. YEAR 2015 INTERSECTION OPERATION Impact Traf-6: Intersection Level of Service. The following intersection would receive a significant impact due to the addition of Phase I Project traffic to year 2015 Base Case volumes (see Table 16.11). x Oyster Point Boulevard / Gateway Boulevard / U.S.101 Southbound Flyover Off-Ramp AM Peak Hour: The Phase I Project would increase volumes by 9.11 percent at a location with unacceptable LOS F Base Case operation. PM Peak Hour: The Phase I Project would degrade acceptable Base Case LOS D operation to unacceptable LOS E operation. This would be a significant impact. CHAPTER 16: TRANSPORTATION AND CIRCULATION OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 16-37 Mitigation Measure Traf-6: Oyster Point Boulevard / Gateway Boulevard / U.S.101 Southbound Flyover Off-Ramp (see Table 16.23 and Figure 23 in Appendix E) The following improvements would mitigate the Phase I Project-specific impacts. All of these improvements (other than measures to the Southbound Flyover Off-Ramp, the eastbound departure and the southbound approach) are included as part of the East of 101 Transportation Improvement Program (TIP) and will be funded via the Phase I Project’s traffic impact fee contribution to this program. The Phase I Project shall also provide a fair share contribution towards all measures currently not part of the TIP. Adjust signal timing. Provide an additional through lane on the Oyster Point westbound approach (extending from Veterans Boulevard) and continue to the Dubuque/U.S.101 Northbound On-Ramp intersection. Restripe the Oyster Point Boulevard eastbound approach from a left, 2 throughs and a combined through/right turn lane to a left, 2 throughs and an exclusive right turn lane. Restripe the Southbound Flyover Off-Ramp approach from 2 through lanes and an exclusive right turn lane to two through lanes and a combined through/right turn lane. In conjunction with this measure, add a third eastbound departure lane on Oyster Point Boulevard (not part of TIP). Add a second exclusive right turn lane on the southbound Genentech property driveway approach (not part of TIP). Resultant 2015 Base Case + Phase I Project Operation: AM Peak Hour: LOS E-79.8 seconds control delay, which is better than LOS F 91.7 seconds control delay Base Case operation. PM Peak Hour: LOS D-54.7 seconds control delay, which is acceptable operation. Impact reduced to a less-than-significant level. The City’s East of 101 Transportation Improvement Program provides a mechanism for collecting fair share contributions toward necessary area improvements and pooling them to pay for these improvements. This program is funded via the traffic impact fee that is assessed with all new projects in the area. The planned implementation of these improvements would maintain or improve the current levels of service at these intersections (see Table 16.23), which would mitigate potential Phase I Project impacts.

The Oyster Point Boulevard / Veterans Boulevard intersection is included in the City’s East of 101 Transportation Improvement Program. Therefore, a portion of the traffic impact fee collected for the proposed Phase I Project will be used to help fund planned improvements to this intersection that would maintain or improve the current levels of service and reduce the Phase I Project’s impact to a level of less-than-significant. Impact Traf-8: Intersection Level of Service. The following intersection would receive a significant impact due to the addition of Phase I Project traffic to year 2015 Base Case volumes (see Table 16.11). x Gateway Boulevard / S.

The Gateway Boulevard / S. Airport Boulevard / Mitchell Avenue intersection is included in the City’s East of 101 Transportation Improvement Program. The proposed Phase I Project will pay to fund planned improvements to this intersection that would maintain or improve the current levels of service and reduce the Phase I Project’s impact to a level of less-than-significant. The proposed Phase I Project would not result in significant impacts at other intersections experiencing unacceptable Base Case operation as Phase I Project volume increases would be less than 2 percent.

The following off-ramp/approach to an adjacent intersection leading away from an off- ramp would receive a significant queuing impact due to the addition of Phase I Project traffic to year 2015 Base Case volumes (see Table 16.12). x Airport Boulevard / Sister Cities Boulevard / Oyster Point Boulevard The Phase I Project would increase volumes by 3.0 percent in the through and combined/through right turn lane on the Oyster Point Boulevard westbound approach to Airport Boulevard at a location with Base Case 95th percentile queuing greater than established standards. The through lane or through/right turn lane queue would be extended from 283 to 287 feet at a location with only 250 feet of storage. This would be a significant impact. Mitigation Measure Traf-9: Improvements for Vehicle Queuing. (see Figure 23 in Appendix E) The following improvements would mitigate the Phase I Project-specific impact.

CHAPTER 16: TRANSPORTATION AND CIRCULATION OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 16-41 Impact Traf-10: 95th Percentile Vehicle Queuing — Synchro software evaluation. The following approach to an adjacent intersection leading away from an off-ramp would receive a significant queuing impact due to the addition of Phase I Project traffic to year 2015 Base Case volumes (see Table 16.12). x Oyster Point Boulevard / Dubuque Avenue AM Peak Hour: The Phase I Project would increase volumes by 6.5 percent in the through lanes on the Oyster Point Boulevard eastbound approach to Dubuque Avenue at a location with Base Case 95th percentile queuing greater than established standards. The 95th percentile vehicle queue would be extended from 309 up to about 327 feet in a location with only 250 feet of storage. This would be a significant impact.

Impact reduced to a less-than-significant level. The Oyster Point Boulevard / Dubuque Avenue intersection is included in the City’s East of 101 Transportation Improvement Program. Therefore the proposed Phase I Project will pay to fund planned improvements to this intersection that would improve vehicle queuing capacity and reduce the Phase I Project’s impact to a level of less-than-significant. The proposed Phase I Project would not increase traffic more than one percent on the approaches to any other location which is projected to experience year 2015 Base Case 95th percentile queuing greater than established standards.

This would be a significant impact. Mitigation Measure Traf-11: Improvements for Off-Ramp Queuing. The following improvements would mitigate the Phase I Project-specific impacts. These improvements are not included in the East of 101 Transportation Improvement Program. x U.S.101 Southbound Flyover Off-Ramp to Oyster Point Boulevard / Gateway Boulevard (see Table 16.23 and Figure 23 in Appendix E) The following improvements would mitigate the Phase I Project-specific impacts. All of these improvements (other than measures to the Southbound Flyover Off-Ramp, eastbound departure and southbound approach) are included as part of the East of 101 Transportation Improvement Program (TIP) and will be funded via the Phase I Project’s traffic impact fee contribution to this program. The Phase I Project shall also provide a fair share contribution towards all measures currently not part of the TIP.

YEAR 2015 FREEWAY MAINLINE AND ON/OFF-RAMP OPERATION Impact Traf-13: Off-Ramp Operation At Mainline Diverge. The following off-ramp diverge location from the U.S.101 freeway mainline would receive a significant impact due to the addition of Phase I Project traffic to year 2015 Base Case volumes (see Table 16.6). x U.S.101 Southbound Flyover Off-Ramp to Oyster Point Boulevard AM Peak Hour: The Phase I Project would increase volumes by 8.2 percent at a location where Base Case diverge volumes would already be exceeding 1,500 vehicles per hour (from 1,618 up to 1,750 VPH). This would be a significant impact. Mitigation Measure Traf-13: Off-Ramp Operation At Mainline Diverge. x U.S.101 Southbound Flyover Off-Ramp to Oyster Point Boulevard No improvements are feasible to mitigate Phase I Project-specific impacts. The spacing of southbound off-ramp connections to Airport Boulevard and to Oyster Point Boulevard precludes the possibility of providing a second off-ramp lane connection to southbound U.S.101 to serve the Oyster Point Boulevard southbound off-ramp. A second off-ramp lane connection to the freeway mainline would require a long (1,000-foot or longer) deceleration lane with only 300 feet of available space. There is no room for provision of this lane. IMPACT WOULD REMAIN SIGNIFICANT & UNAVOIDABLE. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 16-44 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Impact Traf-14: Off-Ramp Operation At Mainline Diverge. The following off-ramp diverge location from the U.S.101 freeway mainline would receive a significant impact due to the addition of Phase I Project traffic to year 2015 Base Case volumes (see Table 16.6). x U.S.101 Northbound Off-Ramp to Dubuque Avenue AM Peak Hour: The Phase I Project would increase volumes above the 1,500 VPH limit for single lane off-ramp diverge volumes (from 1,356 up to 1,536 VPH). This would be a significant impact. Mitigation Measure Traf-14: Improvements for Off-Ramp Operation At Mainline Diverge. (see Figure 23 in Appendix E). x U.S.101 Northbound Off-Ramp to Dubuque Avenue x Provide a second off-ramp lane connection to the U.S.101 mainline. Off-ramp diverge capacity would be increased to at least 2,200 vehicles per hour, which would accommodate the Base Case + Phase I Project AM peak hour volume of 1,536 vehicles per hour. This measure will require the approval of Caltrans. Also, this measure is currently not included in the East of 101 Traffic Impact Fee list. It should be noted that because the improvement is within Caltrans’ jurisdiction, the City of South San Francisco, as lead agency for the project, cannot guarantee that the mitigation will be implemented While it is likely that Caltrans will implement the measure, thereby reducing the impact to a less than significant level, because the measure is beyond the lead agency’s jurisdiction, for CEQA purposes, this impact is considered to be significant and unavoidable. IMPACT WOULD REMAIN SIGNIFICANT & UNAVOIDABLE. Phase I Project traffic would not significantly increase volumes nor produce a significant impact at the other four U.S.101 off-ramp locations in South San Francisco. Impact Traf-15: On-Ramp Operation. Phase I Project traffic would not produce a significant impact at any on-ramp (see Table 16.7). This would be a less-than-significant impact, therefore no mitigation is required. Impact Traf-16: Freeway Mainline Operation. No U.S.101 mainline segment would receive a significant impact due to the addition of Phase I Project traffic to year 2015 Base Case volumes. Operation would remain LOS D or better at all locations (see Table 16.13). This would be a less-than-significant impact, therefore no mitigation is required.

No improvements are feasible to mitigate the OPSP-specific impact. IMPACT WOULD REMAIN SIGNIFICANT & UNAVOIDABLE. YEAR 2035 FREEWAY MAINLINE AND ON/OFF-RAMP OPERATION Impact Traf-33: Off-Ramp Operation At Mainline Diverge. The analysis concluded that there would be a significant impact at the Southbound Flyover Off-Ramp Diverge to the Oyster Point / Gateway Boulevard intersection due to the addition of OPSP traffic to year 2035 Base Case volumes (see Table 16.6). AM peak hour volumes would be increased by 16.6 percent (from 2,107 up to 2,456 vehicles per hour) at a location where Base Case volumes would already be exceeding the off-ramp diverge capacity of 1,500 vehicles per hour. This would be a significant impact. Mitigation Measure Traf-33: Improvement to Diverge Capacity – U.S.101 Southbound Flyover Off-Ramp to Oyster Point Boulevard No improvements are feasible to mitigate OPSP-specific impacts. The spacing of southbound off-ramp connections to Airport Boulevard and to Oyster Point Boulevard precludes the possibility of providing a second off-ramp lane connection to southbound U.S.101 to serve the Oyster Point Boulevard southbound off-ramp. A second off-ramp lane connection to the freeway mainline would require a long (1,000-foot or longer) deceleration lane with only 300 feet of available space. There is no room for provision of this lane. IMPACT WOULD REMAIN SIGNIFICANT & UNAVOIDABLE. Impact Traf-34: Off-Ramp Operation At Mainline Diverge. The analysis concluded that there would be a significant impact at the Northbound Off-Ramp Diverge to the Dubuque Avenue due to the addition of OPSP traffic to year 2035 Base Case volumes (see Table 16.6). AM peak hour volumes would be increased by 28.7 percent (from 1,556 up to 2,002 vehicles per hour) at a location where Base Case volumes would already be exceeding the off-ramp diverge capacity of 1,500 vehicles per hour. This would be a significant impact. Mitigation Measure Traf-34: Improvement to Diverge Capacity U.S.101 Northbound Off-Ramp to Dubuque Avenue. The following improvements would mitigate the OPSP- specific impact (see Figure 24 in Appendix E). Provide a second off-ramp lane connection to the U.S.101 mainline. Off-ramp diverge capacity would be increased to at least 2,200 vehicles per hour, which would accommodate the Base Case + OPSP AM peak hour volume of 1,556 DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 16-56 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT vehicles per hour. This measure will require the approval of Caltrans. Also, this measure is currently not included in the East of 101 TIP. Therefore, the OPSP shall provide a fair share contribution towards this measure. It should be noted that because the improvement is within Caltrans’ jurisdiction, the City of South San Francisco, as lead agency for the OPSP, cannot guarantee that the mitigation will be implemented While it is likely that Caltrans will implement the measure, thereby reducing the impact to a less than significant level, because the measure is beyond the lead agency’s jurisdiction, for CEQA purposes, this impact is considered to be significant and unavoidable. IMPACT WOULD REMAIN SIGNIFICANT & UNAVOIDABLE. OPSP traffic would not significantly increase volumes nor produce a significant impact at the other four U.S.101 off-ramp locations in South San Francisco. Impact Traf-35: On-Ramp Operation. The analysis concluded that there would be a significant impact at the Northbound On-Ramp from Oyster Point Boulevard / Dubuque Avenue due to the addition of OPSP traffic to year 2035 Base Case volumes (see Table 16.7). PM peak hour volumes would be increased by 17.0 percent (from 2,190 up to 2,563 vehicles per hour) at a location where Base Case volumes would be just less than the on-ramp capacity of 2,200 vehicles per hour. This would be a significant impact. Mitigation Measure Traf-35: Improvement to On-Ramp Capacity Northbound On-Ramp from Oyster Point Boulevard / Dubuque Avenue (see Figure 24 in Appendix E). Provision of a second on-ramp lane would increase capacity to about 3,000 to 3,100 vehicles per hour. This measure will require the approval of Caltrans. Also, this measure is currently not included in the East of 101 TIP. Therefore, the OPSP shall provide a fair share contribution towards this measure. It should be noted that because the improvement is within Caltrans’ jurisdiction, the City of South San Francisco, as lead agency for the OPSP, cannot guarantee that the mitigation will be implemented While it is likely that Caltrans will implement the measure, thereby reducing the impact to a less than significant level, because the measure is beyond the lead agency’s jurisdiction, for CEQA purposes, this impact is considered to be significant and unavoidable. There are no other physical improvements possible acceptable to Caltrans to accommodate the Base Case + OPSP volume of about 2,563 vehicles per hour. IMPACT WOULD REMAIN SIGNIFICANT & UNAVOIDABLE. Impact Traf-36: On-Ramp Operation. The analysis concluded that there would be a significant impact at the Southbound On-Ramp from Dubuque Avenue due to the addition of OPSP traffic to year 2035 Base Case volumes (see Table 16.7). PM peak hour volumes would be increased by 11.5 percent (from 1,906 up to 2,125 vehicles per hour) at a location where Base Case volumes would be just less than the on-ramp capacity of 2,000 vehicles per hour. This would be a significant impact. CHAPTER 16: TRANSPORTATION AND CIRCULATION OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 16-57 Mitigation Measure Traf-36: Improvement to On-Ramp Capacity Southbound On-Ramp from Dubuque Avenue (see Figure 24 in Appendix E). This OPSP should provide a fair share contribution as determined by the City Engineer to the following measure. Provide a second on-ramp lane connection to the U.S.101 freeway. On-ramp capacity would be increased from 2,000 up to 3,000 vehicles per hour, with a Base Case + OPSP PM peak hour volume of about 2,125 vehicles per hour. This measure will require the approval of Caltrans. Also, this measure is currently not included in the East of 101 TIP. Therefore, the OPSP shall provide a fair share contribution towards this measure. It should be noted that because the improvement is within Caltrans’ jurisdiction, the City of South San Francisco, as lead agency for the OPSP, cannot guarantee that the mitigation will be implemented While it is likely that Caltrans will implement the measure, thereby reducing the impact to a less than significant level, because the measure is beyond the lead agency’s jurisdiction, for CEQA purposes, this impact is considered to be significant and unavoidable. IMPACT WOULD REMAIN SIGNIFICANT & UNAVOIDABLE. Impact Traf-37: Freeway Mainline Operation. One U.S.101 mainline segments would receive a significant impact due to the addition of OPSP traffic to year 2035 Base Case volumes (see Table 16.18). x U.S.101 Southbound (to the north of the Oyster Point interchange) AM Peak Hour: The OPSP would increase volumes by 3.6 percent (from 9,698 up to 10,047 vehicles per hour) at a location with unacceptable LOS F year 2035 Base Case operation. This would be a significant impact. Mitigation Measure Traf-37: Improvement to Freeway Mainline. Mitigation of this impact would require widening the current freeway or construction of a new freeway. Given the location of the mainline freeway and its close proximity to surrounding development, such mitigation is not feasible. Additionally, such mitigation would be prohibitively expensive in relation to the types of land uses it would benefit. Given these specific concerns, mitigation of Impact 14A is not feasible as defined by CEQA. (See Pub. Resources Code §21061.1 (defining “feasible” as “capable of being accomplished…taking into account economic…and technological factors.”).) Under CEQA, the City in this matter has an obligation to balance public objectives, including specific economic concerns, against the benefits of the project. (See Pub. Resources Code §21081. subd. (a)(3); CEQA Guidelines, §15021. subd. (d).) Where economic concerns render a particular mitigation measure infeasible, the lead agency may reject the measure. (See Pub. Resources Code §21081. subd. (a)(3).) IMPACT WOULD REMAIN SIGNIFICANT & UNAVOIDABLE. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 16-58 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PARKING Parking supply was eliminated from the state’s CEQA Guidelines with the revisions that became effective in March 2010. The Court of Appeals has held that parking is not part of the permanent physical environment, that parking conditions change over time as people change their travel patterns, and that unmet parking demand created by a project need not be considered a significant environmental impact under CEQA unless it would cause significant secondary effects.2 Parking supply/demand varies by time of day, day of week, and seasonally. Parking deficits are an inconvenience to drivers, but not a significant physical impact on the environment. Decreased availability and increased time and potentially monetary costs result in changes to people’s mode and pattern of travel. However, parking deficits may be associated with secondary physical environmental impacts, such as air quality and noise effects, caused by congestion resulting from drivers circling as they look for a parking space. Cars circling and looking for a parking space in areas of limited parking supply is typically a temporary condition, often offset by a reduction in vehicle trips due to others who are aware of constrained parking conditions in a given area. Emissions for cars looking for parking would not be anticipated to contribute substantially to regional air quality or greenhouse gas and it is anticipated that such a temporary condition would lead to improved trip reduction under the required TDM Plan. The City of South San Francisco promotes reduction in parking from City zoning standards as a way to support trip reduction goals required per the City’s TDM ordinance and supported by various policies in the General Plan (G.P. Policies 4.3-1-8, 11 and 12). While the parking in the OPSP area is anticipated to be below that required by City code criteria, such a reduction is promoted by various policies in the General Plan (G.P. Policies 4.3-1-8, 11 and 12) as a way to support trip reduction goals and would not be anticipated to result in secondary impacts, such as increased noise or air emissions from idling cars. A Transportation Demand Management Plan has been prepared and is included in the Appendix E. The targeted reduction in trips would be supported by a reduced amount of parking. This is a non-CEQA item and there would be no impact related to parking. 2 San Franciscans Upholding the Downtown Plan v. the City and County of San Francisco (2002) 102 Cal.App.4th 656. OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 17-1 17 UTILITIES INTRODUCTION This chapter describes existing public utilities on and in the vicinity of the OPSP and evaluates the impact of the proposed OPSP and Phase I Project on the provision of public utilities and possible adverse physical impacts to the environment that could result from constructing expanded facilities. This chapter is based on a utilities study prepared by Carollo Engineers, the full text of which is included in Appendix G (Utilities Study) and the SB 610 Water Supply Assessment prepared by California Water Service Company , included in Appendix F (WSA). SETTING WATER SYSTEM The water system in the East of Highway 101 area is owned and operated by the California Water Service Company (CWSC). CWSC’s supply source consists of eight groundwater wells and surface water wholesaled by the San Francisco Public Utilities Commission (SFPUC). CWSC is a member of the Bay Area Water Supply and Conservation Agency (BAWSCA). CWSC serves three districts on the San Francisco Peninsula: Bear Gulch, Mid Peninsula, and South San Francisco. The South San Francisco District water supply is a combination of purchased water obtained from the SFPUC, groundwater produced from CWSC owned wells, and SB7 conservation generated supply savings.Table 17.1 summarizes the projected water supply sources and their annual quantity for the next 20 years assuming that the SB7 forecasted demand is achieved. TABLE 17.1:SOUTH SAN FRANCISCO DISTRICT WATER SUPPLIES (AFY) Water Supply Sources 2005 Actual 2010 Actual 2015 2020 2025 2030 SFPUC 8,869 8012 7,604 6,931 7,126 7,326 CWSC Groundwater Wells 0 451 1,500 1,500 1,500 1,500 SB7 Conservation Savings 0 0 441 1,335 1,365 1,393 Total (SB7 Baseline Demand) 8,869 8,463 9,545 9,766 9,991 10,219 Purchased Water CWSC purchases treated surface water from the SFPUC. This supply is predominantly from the Sierra Nevada, delivered through the Hetch Hetchy aqueducts, but also includes treated water produced by the SFPUC from its local watersheds and facilities in Alameda and San Mateo Counties. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 17-2 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT The amount of imported water available to SFPUC’s retail and wholesale customers is constrained by hydrology, physical facilities, and the institutional factors that allocate the water supply of the Tuolumne River. Due to these constraints, the SFPUC is very dependent on reservoir storage to firm-up its water supplies. The SFPUC meets its retail and wholesale water demands through an integrated regional water system that includes water from local Bay Area water sources as well as imported water from Hetch Hetchy reservoir. Local watershed facilities are operated to capture local runoff as well as store imported water. Local reservoirs include: Crystal Springs Reservoir, San Andreas Reservoir, Pilarcitos Reservoir, Calaveras Reservoir, and San Antonio Reservoir. The Raker Act, which authorized the Hetch Hetchy project, prevents a privately owned utility such as CWSC from receiving water from the Hetch Hetchy system, but allows local sources to be purchased. In addition, CWSC is subject to the Water Supply Agreement between The City and County of San Francisco and Wholesale Customers in Alameda County, San Mateo County and Santa Clara County. The water purchased is treated by SFPUC prior to delivery to CWSC. The district takes delivery from SFPUC from eleven metered connections from five SFPUC transmission lines. Supply Guarantee In July 2009, CWSC along with 29 other Bay Area water suppliers signed a Water Supply Agreement (SFWSA) between The City and County of San Francisco and Wholesale Customers in Alameda County, San Mateo County and Santa Clara County, which replaced the Settlement Agreement and Master Water Sales Contract (Master Contract) with San Francisco that had been in place since 1984. The SFWSA continues the provision to provide a Supply Guarantee of 184 mgd, expressed on an annual average basis to SFPUC wholesale customers collectively. SFPUC retail customers receive 81 mgd as a supply guarantee. CWSC’s Individual Supply Guarantee (ISG) is 35.68 mgd or 39,967 acre feet per year. The SFPUC can meet the water demands of its retail and wholesale customers in wet and normal years, however; the SFWSA allows the SFPUC to reduce water deliveries during droughts, emergencies, and for scheduled maintenance activities. The SFWSA between the SFPUC and its wholesale customers adopted in July 2009 provides that the SFPUC will determines the available water supply in drought years and call for reductions to deal with these shortages of up to 20% on an average, system-wide basis. A reduction in available supply of greater than 20% would require special negotiation between SFPUC and BAWSCA. Groundwater Groundwater is extracted from CWSC owned wells the Merced Formation of the Colma Creek Basin, a sub-basin of the Merced Valley Groundwater Basin, which is popularly referred to as the Westside Basin. Groundwater supplies ten to fifteen percent of the district’s water demand. The water level has remained relative constant since 1990 due to the area receiving average to above average rainfall and that the wells have been operating at less than 60% of total capacity. The water levels have been rising since 2003 since the wells have been placed off-line as part of a SFPUC program to demonstrate the feasibility of a conjunctive use program. SFPUC proposes to install wells in the Westside Basin, then have CWSC, Daly City and San Bruno not pump their wells during periods of above average precipitation and thereby “bank” the groundwater or increase the quantity of CHAPTER 17: UTILITIES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 17-3 groundwater basin storage. During dry periods when SFPUC anticipates reductions in its deliverable surface supplies, CWSC, Daly City and San Bruno would pump their normal amounts plus additional amounts of the stored water using the SFPUC installed wells to make up for the surface supply cutback. Agreements to implement this plan, which has been demonstrated to be technically feasible, are currently being negotiated among the parties. The South San Francisco District has five active wells with a total design capacity of 955 GPM. If operated full-time, these wells could produce 1.38 mgd (1,540 AFY). This production capacity represents about 17 percent of the annual demand in the district. A maximum of 1,560 AFY was pumped in 1970 and 1983. Over the past two decades, CWSC’s average groundwater production has been 1,015 AFY, due largely to the availability of SFPUC supplies. The future production of groundwater from 2010 to 2030 will be held at 1500 AFY. Based on historical data, future demand projections, contracted treated water deliveries from SFPUC under normal hydrologic conditions and the mandated SB7 conservation savings are expected to generate a surplus SFPUC supply during the period 2015 to 2030 of between 2.0 and 3.84 MGD. Other Potential Supply Plan Opportunities Recycled Water Recycling of wastewater is evaluated by CWSC in the SSF UWMP. Use of recycled water for non- potable uses (e.g., landscape irrigation) can reduce demands on SFPUC and groundwater supplies. Currently, no recycled water is used in the SSF District, though the potential for future recycling for non-potable uses may exist, but are not currently planned. Desalinated Water Desalination of either brackish groundwater or San Francisco Bay water has been assessed by CWSC in its December 2010 Integrated Long Term Supply Plan (ILTSP) for its three peninsula districts that are served by the San Francisco Public Utility Commission (SFPUC). It was found to be potentially feasible and the plan recommends proceeding in the near future with more detailed investigations to further develop technical, cost, environmental and permitting information. In addition to technical and cost feasibility studies, desalination treatment facilities require environmental studies and close coordination with local and state agencies. Conservatively, eight years of lead-time may be required from feasibility and environmental studies and permitting to initiation of construction. Currently, there are no desalinated water supplies available. Water Transfer Agreements and Exchanges As indicated in the ILTSP for the three peninsula districts, CWSC is pursuing water transfer agreements with water agencies in the Central Valley (CV). With the right source and water agency, water could be acquired by CWSC and transferred to the Tuolumne River Basin for subsequent SFPUC conveyance, treatment and delivery to CWSC’s three peninsula districts. Another option is to acquire water from an agency that is a state water contractor and negotiate a transfer with Department of Water Resources (DWR) for delivery to the Santa Clara Valley Water District (SCVWD) via the State Water Project (SWP) to the South Bay Aqueduct for transmission, treatment and transfer to CWSC’s Los Altos Suburban District (LAS), which is served by SCVWD. CWSC could negotiate an exchange with another agency that is served by both SFPUC and SCVWD so that instead of taking SFPUC water, the agency received SCVWD water that is not used by CWSC. This would help increase groundwater storage in LAS since less groundwater would be pumped under this plan. Another option is for CWSC DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 17-4 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT to transfer acquired CV supply treated by SCVWD to its Bear Gulch District through a newly constructed pump station and pipeline. Initial transfers amounts of approximately 4,000 to 6,000 AFY would increase SSF district supply since SFPUC supply to the three peninsula districts is treated as a whole, i.e., CWSC can decide which district receives the added supply credit. CWSC envisions that it would take 3 to 5 years to develop a water supply transfer agreement and address all planning, environmental and engineering requirements. Existing OPSP Area Water System The OPSP area is supplied from a 16-inch diameter water main in Oyster Point Boulevard. From there, mains in Oyster Point Boulevard, Marina Boulevard and along the north side of the waterfront serve the various portions of the OPSP area. (Figure 3 in Appendix G illustrates the storm drainage facilities.) WASTEWATER COLLECTION SYSTEM The existing wastewater system serving the OPSP site and surrounding community is operated and maintained by the City of South San Francisco Public Works Department. The complete sewer network consists of approximately 155 miles of 6-inch through 36-inch diameter pipes, which convey flows from the cities of South San Francisco, San Bruno, and portions of Daly City and Colma to the South San Francisco-San Bruno Water Quality Control Plant (WQCP) located at the end of Belle Air Road in South San Francisco.1 Since the first construction in 1945, the jointly owned South San Francisco and San Bruno WQCP Plant has undergone many upgrades and expansions. The last major expansion occurred in 2000. Currently, the plant processes include preliminary treatment (headworks), primary clarifiers, secondary treatment utilizing an air activated sludge process, effluent disinfection and dechlorination. An overview of the existing facilities is provided in Figure 5 in Appendix G. The treated effluent is discharged to the San Francisco Bay in a 54-inch diameter submarine gravity outfall. The most recent WQCP upgrade project was completed in 2005. The project included improvements to accommodate peak wet weather flows, including a 7-million gallon (MG) secondary effluent storage basin, an expansion of the influent pump station, and an effluent pump station. The WQCP currently has an average dry weather flow capacity of 13 mgd and a wet weather flow capacity of 62 mgd. The City is implementing a new capital improvement plan (CIP) to increase wet weather flow capacity, add reliability improvements, and add green energy facilities. The CIP will be implemented in several phases over the next 10 years. Existing OPSP Area Wastewater System The City’s wastewater collection system in the East of Highway 101 area consists of approximately 13 miles of 6-inch through 30-inch diameter sewers (see Figure 4 in Appendix G). The system consists of a series of gravity sewers and pump stations that convey flow to the main pump station (Pump Station No 4); Pump Station No. 7 conveys a small portion of the East of 101 area to the WQCP as well. The portion of the City’s collection system that serves the Oyster Point development area includes the Oyster Point Subtrunk, Pump Station No. 2, the Gateway Trunk, the Harbor Way Trunk, Pump Station 1 City of South San Francisco, prepared by Lamphier-Gregory, 249 East Grand Ave EIR, 2005 CHAPTER 17: UTILITIES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 17-5 No 4, and the Pump Station No. 4 Forcemain. Pump Station No. 1 is existing on and currently serving the business park uses along Oyster Point Boulevard in this area. STORM DRAINAGE SYSTEM The storm water system consists of a variety of disconnected drainage systems, including surface street drainage, and underground storm drains that drain to numerous outfalls that discharge to the San Francisco Bay (Bay) along the north, west, and eastern sides of Oyster Point. (Figure 6 in Appendix G illustrates the storm drainage facilities.) Stormwater flow from the outfalls is not treated. Existing OPSP Area Storm Drainage System The quantity of storm runoff during rainfall events is affected by the percentage of impervious surfaces versus pervious surfaces. Impervious surfaces, such as pavement and buildings, cause more runoff than pervious surfaces such as landscaped areas. The area of impervious surfaces for the existing development was estimated using aerial imagery and geographical information system (GIS) software. Figure 7 in Appendix G illustrates the pervious and impervious areas prior to development of the OPSP. The existing impervious area covers approximately 45 of the total 80 acres, or 57 percent of the total area. REGULATORY SETTING Wastewater treatment and disposal in the City of South San Francisco is governed by laws, regulatory programs and policies established by the Federal government, the State of California, the San Francisco Bay RWQCB, and the City of South San Francisco. Most of the pertinent requirements affecting wastewater facilities for the proposed OPSP are contained in the following: Federal Laws and Regulations Clean Water Act (CWA) The Clean Water Act (CWA) was enacted by Congress in 1972 and amended several times since its inception. It is the primary federal law regulating water quality in the United States, and forms the basis for several state and local laws throughout the country. Its objective is to reduce or eliminate water pollution in the nation’s rivers, streams, lakes, and coastal waters. The CWA prescribed the basic federal laws for regulating discharges of pollutants as well as set minimum water quality standards for all waters of the United States. At the Federal level, the CWA is administered by the U.S. Environmental Protection Agency (EPA). At the state and regional level, the CWA is administered and enforced by the State Water Resources Control Board (SWRCB) and the Regional Water Quality Control Boards (RWQCBs). The State of California has developed a number of water quality laws, rules, and regulations to assist in the implementation of the CWA and related Federally mandated water quality requirements. In many cases, the Federal requirements set minimum standards, and the laws, rules, and regulations adopted by the State and Regional Boards are more restrictive, i.e. more protective of the environment. State Laws and Regulations Porter-Cologne Water Quality Control Act The Porter-Cologne Water Quality Control Act establishes the SWRCB and the RWQCB as the principal state agencies having primary responsibility for coordinating and controlling water quality in DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 17-6 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT California. The Porter-Cologne Act establishes the responsibility of the RWQCBs for adopting, implementing, and enforcing water quality control plans (Basin Plans), which set forth the state’s water quality standards (i.e. beneficial uses of surface waters and groundwater) and the objectives or criteria necessary to protect those beneficial uses. San Francisco Bay Water Quality Control Plan (Basin Plan) The San Francisco Bay RWQCB is responsible for the development, adoption, and implementation of the Water Quality Control Plan (Basin Plan) for the San Francisco Bay region. The Basin Plan is the master policy document that contains descriptions of the legal, technical, and programmatic bases of water quality regulation in the San Francisco Bay Region. The Basin Plan identifies beneficial uses of surface waters and groundwater within its region and specifies effluent limitations, discharge prohibitions, and water quality objectives to maintain the existing potential beneficial uses of the waters. The proposed OPSP is required to adhere to all applicable requirements of the Basin Plan. National Pollution Discharge Elimination System Permit Requirements The San Francisco-San Bruno WQCP operates under an NPDES permit issued by RWQCB under the authority of the State of California. One of the requirements of the permit is that the WQCP implement a Pretreatment Program to regulate the collection of toxic and hazardous wastes in municipal sewers. Under the Pretreatment Program, dischargers of industrial wastewater are required to abide by specific wastewater discharge limits and prohibitions. Industrial dischargers are also required to submit self- monitoring reports on the total volume and pollutant concentrations of their wastewater, and to allow for inspections by the City of South San Francisco. The National Pollutant Discharge Elimination System Municipal Regional Stormwater Permit (Provision C3) for South San Francisco, requires that best management practices (BMPs) and low impact development (LID) practices be implemented as part of the redevelopment of the OPSP area. Local Programs and Regulations East of 101 Area Plan The East of 101 area plan was adopted by the City of South San Francisco in 1994 in order to guide and regulate development in the City’s East of 101 area, which includes the OPSP site. The Plan provides detailed planning policies for land use, circulation, public facilities, design, conservation, financing and other related elements. With respect to wastewater collection and treatment, the Plan outlines policies for the repair and reconstruction of East of 101 area sewer collection lines, pump stations, and the WQCP. The Plan also addresses the issue of increasing wastewater treatment demand, and recommends that new projects that will generate large wastewater quantities be required to lower their wastewater treatment needs through water recycling, on-site treatment, graywater irrigation, or other similar technologies wherever feasible. STORM DRAINAGE FACILITIES The existing drainage system in the East of 101 area is generally designed and constructed for industrial development, which has a high ratio of impervious surfaces. Thus, any redevelopment of existing development will generally not increase runoff. CHAPTER 17: UTILITIES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 17-7 SOLID WASTE Solid waste is collected from South San Francisco homes and businesses and then processed at the South San Francisco Scavenger Company’s materials recovery facility and transfer station. Materials that cannot be recycled or composted are transferred to the Ox Mountain Sanitary Landfill, near Half Moon Bay. Browning-Ferris Industries, owner of the landfill, has a permit for forward expansion of the Corinda Los Trancos Canyon at Ox Mountain. When the permit expires, either Corinda Los Trancos will be expanded further or Apanolio Canyon will be opened for fill. In 2005, the City landfilled approximately 85,091 tons. The landfill has a permitted maximum disposal of 3,598 tons per day. As of 2000 (the most recent quantification available), the landfill has exceeded its originally permitted capacity of 37.9 million cubic yards by approximately 6.7 million cubic yards (17.8 percent). The operators are permitted until 2018 to expand the Ox Mountain landfill capacity and they continue to accept waste as the landfill gradually settles and new space becomes available. The closure date is planned for 2018.2 After collection, waste is brought to the Scavenger Company’s Blue Line Transfer, Inc. facility, a public disposal and recycling center located at 500 East Jamie Court. The Blue Line Transfer facility is permitted to receive a daily maximum of 2,400 tons per day of wastes and recyclable materials3, but receives an average of approximately 800 tons per day4. This facility gives the Company increased capability to recover valuable materials from wastes, reducing the amount of waste being sent to the landfill. South San Francisco recycles both household and industrial solid waste and sewage sludge and has an estimated diversion rate of 40%.5 IMPACTS AND MITIGATION MEASURES STANDARDS OF SIGNIFICANCE The following thresholds for measuring a Project’s environmental impacts are based upon CEQA Guidelines: 1.Would the project exceed wastewater treatment requirements of the applicable Regional Water Quality Control Board? 2.Would the project require substantial expansion or alteration of the City’s water or wastewater treatment and collection facilities? 3.Would the project require or result in the construction of new storm water drainage facilities or expansion of existing facilities? 2 California Integrated Waste Management Board, Active Landfills Profile for Ox Mountain Sanitary Landfill (41-AA-0002), website: http://www.ciwmb.ca.gov/Profiles/Facility/Landfill/LFProfile1.asp?COID=7&FACID=41-AA-0002, accessed December 17, 2010. 3 San Mateo County, Countywide Integrated Waste Management Plan, Multi-Jurisdiction Non-Disposal Facility Element (NDFE), draft June 2010 amendment. 4 City of South San Francisco, prepared by Christopher A. Joseph & Associates, Gateway Business Park Master Plan Draft Environmental Impact Report, October 2009, page IV.N-8 5 San Mateo County, Countywide Integrated Waste Management Plan, Multi-Jurisdiction Non-Disposal Facility Element (NDFE), draft June 2010 amendment DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 17-8 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT 4.Would the project have sufficient water supplies available to serve the project from existing entitlements and resources, or are new or expanded entitlements needed? 5.Would the project result in a determination by the wastewater treatment provider which serves or may serve the project that it has adequate capacity to serve the project’s projected demand in addition to the provider’s existing commitments? 6.Would the project be served by a landfill with sufficient permitted capacity to accommodate the project’s solid waste disposal needs? 7.Would the project comply with federal, state, and local statutes and regulations related to solid waste? WATER SUPPLIES Impact Util-1: Increased Water Demand. Build-out of the OPSP area would increase water demand and use of the local water system. However, according to the Water Supply Assessment and Utilities Study, there is sufficient water supply through the year 2030, including the increased demand from the OPSP, and adequate water system capacity. This is a less-than-significant impact. Projected Plan Water Flows The WSA prepared for the OPSP (Appendix F) estimated a total net new water demand for the Phase I Project of 43,038 gpd and for the OPSP of 239,023 gpd. These estimates are conservative, as they are based upon water usage assumptions for older buildings (1980s) that do not employ current water efficiency measures. The actual water usage within the OPSP is anticipated to be lower than this estimate. OPSP-Proposed Improvements The OPSP proposes a new on-site distribution system consisting of new 12-inch diameter water mains routed along the realigned Marina Boulevard and Oyster Point Boulevard. The new mains will branch from the existing 16-inch water main in Oyster Point Boulevard and connect with the existing 8-inch water main on the marina waterfront to form distribution loops around the marina facilities. The new 12-inch diameter loop system is subject to review by CWSC. (Figure 9 in Appendix G illustrates the proposed water system.) Supply and System Capacity The OPSP area is currently served with a 16-inch diameter water main located in Oyster Point Boulevard. According to CWSC staff, the 16-inch main is adequate to serve the OPSP with adequate water pressure and flow. Accordingly, no impacts to the water main system are anticipated from the development of Phase I Project or entire OPSP. According to the WSA, a surplus SFPUC supply is anticipated during the period 2015 to 2030 of between 2.0 and 3.84 MGD. The projected demand for the OPSP is 0.24 MGD. Therefore, CWSC believes under normal hydrologic conditions supplies will be adequate to meet the projected 20-year demand for the SSF District including OPSP with its forecasted increase of SFPUC supplies, groundwater supplies, increased demand management or conservation. CWSC has indicated that they will provide the developer of OPSP developer with a will serve letter indicating its intention to provide water service after the proposed development is approved by the City of South San Francisco. CHAPTER 17: UTILITIES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 17-9 Therefore, the impact of increased water demand on water supply and system capacity will be less than significant. WASTEWATER Impact Util-2: Exceed Existing Pump Station and Subtrunk Wastewater Capacity. The additional wastewater flows from the construction of the total OPSP will exceed the hydraulic capacities of the existing Oyster Point Subtrunk, and Pump Station No. 2. The inadequate capacity to serve the project’s projected demand of the wastewater subtrunk and pump station is a potentially significant impact. Projected Plan Wastewater Flows The 2007 East of 101 Sewer System Master Plan Update (Sewer Master Plan) estimated wastewater flows for the East of 101 area at 90 percent of the water demands. Based on this ratio, the average daily wastewater flow for the total OPSP is estimated at 0.36 mgd. The average daily wastewater flow from the Phase I Project is estimated at 0.072 mgd. The hydraulic model of the sewer collection system developed for the Sewer Master Plan was used to assess the impacts of wastewater flows from the OPSP. The model simulates hourly dry weather flow variations in the sewers, and peak flows during wet weather. High flows during wet weather come from extraneous flows (groundwater, stormwater, also known as infiltration and inflow) that enter the sewer through pipe defects such as off-set joints or cracks. Table 17.2 summarizes the net change in wastewater flow for average and peak wet weather flow conditions. According to the model, the construction of the Phase I Project will increase the average daily flow by 0.05 mgd (from 0.09 mgd to 0.14 mgd). The peak wet weather flow (PWWF) will increase by 0.13 from (0.25 mgd to 0.38 mgd). The construction of the total OPSP will increase the ADF by 0.28 mgd (from 0.09 mgd to 0.37 mgd). The PWWF would increase by 0.61 mgd (from 0.25 mgd to 0.86 mgd). Table 17.2: Existing and Projected Sewer Flows OPSP-Proposed Improvements To accommodate the realignment of a portion of Oyster Point Boulevard and Marina Boulevard, the existing sewer system in this area will need to be revised. Figure 10 in Appendix G shows the proposed changes. Pump Station No. 1, located on Oyster Point Boulevard across from north end of Oyster Point DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 17-10 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Park, will be relocated to north of the intersection of Oyster Point Boulevard and Marina Boulevard and configured to pump flow through a new 8-inch diameter forcemain. The new pump station will have three dry well submersible pumps equipped with variable frequency drives. The new 8-inch diameter forcemain will discharge flow to the existing 8-inch diameter gravity sewer in Oyster Point Boulevard near the intersection of Oyster Point Boulevard and Gull Road. Future developments on the eastern portion of the OPSP area, including the proposed future hotel, will drain to new gravity sewers and a new pump station (not yet numbered). The pump station will pump flows into a new 6-inch diameter forcemain. The 6-inch forcemain will discharge flow at the same discharge point for Pump Station 1, at a common manhole. Pump Station The Sewer Master Plan recommended expanding Pump Station No. 2 in order to convey future flows. The “firm capacity” is the pump station’s capacity with its largest pump out of service. Pump stations need to have sufficient firm capacity to convey peak flows. The existing firm capacity of Pump Station No. 2 is 1.4 mgd. Existing peak wet weather flows at Pump Station No.2 reach 1.1 mgd. With the development of the Phase I Project, the peak wet weather flows to Pump Station No. 2 increase to 1.16 mgd. Development of the total OPSP increases the peak flows to 1.6 mgd. Therefore, the development of the Phase I Project will not trigger an upgrade of Pump Station No. 2. as the projected peak flow can be accommodated within the existing capacity, but once the total OPSP is developed, Pump Station No. 2 will need to be expanded to a firm capacity of 1.6 mgd to accommodate projected flows. The Sewer Master Plan recommended expanding Pump Station No. 2 in order to convey future flows. The existing firm capacity of Pump Station No. 2 is 1.4 mgd. Existing peak flows at Pump Station No.2 reach 1.1 mgd. Mitigation Measure Util-2a: Upsize Pump Station No. 2. To provide the required sewer capacity for the Plan, Pump Station No. 2 will need to be upsized to a firm capacity of 1.6. The Sewer Master Plan includes expanding Pump Station No. 2. Improvements under the Sewer Master Plan are funded through a flat-rate sewer connection fee for new development and a monthly impact fee. The amount of the impact fee is based on the quantity (flow) of wastewater generated. The occupants of the proposed OPSP development shall pay the sanitary sewer fees imposed by the City of South San Francisco in order to mitigate the cost of the pump station upgrade necessary to manage the wastewater flows generated by the OPSP. With the expansion of Pump Station No. 2 included in the Sewer Master Plan, impacts related to pump station capacity would be reduced to less than significant. Note that there are geology/soils considerations related to utilities. These are discussed and addressed in Chapter 9: Geology and Soils, including the potential for differential settlement throughout the area causing stresses at utility connections and in utility lines and the potential for disruption of the flow gradient (Impact and Mitigation Measure Geo-12) This potential utility-related geology/soils impact can be mitigated to a level of less than significant through implementation of the recommended mitigation measures. CHAPTER 17: UTILITIES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 17-11 Sewer Trunk Capacity Evaluation criteria from the Sewer Master Plan were used to determine the impacts from the increased wastewater flows. The criteria defines a sewer trunk as deficient if the depth of flow to pipeline diameter (d/D) for peak dry weather flow (PDWF) conditions is greater than 0.9. During PWWF, a sewer trunk is deficient if the hydraulic grade line rises to within one foot of the manhole rim elevation. According to modeling results, the existing sewer trunk lines have enough capacity of convey the increase in flow resulting from the construction of the Phase I Project. The projected increase in flow from the construction of the total OPSP creates capacity deficiencies in the existing Oyster Point Subtrunk from Pump Station No. 2 to the intersection of Oyster Point Boulevard and Gull Road. The deficient segments of sewer trunk are illustrated in Figure 12 in Appendix G and described in mitigation measure Util-1b, below. Mitigation Measure Util-2b: Oyster Point Subtrunk Replacement. To provide the required sewer capacity, the Oyster Point Subtrunk will need to be replaced with a larger sized trunk line, with sizes ranging from 12, 15, and 18-inches. The majority of these improvements are included in the Sewer Master Plan and are funded through a flat-rate sewer connection fee for new development and a monthly impact fee. The amount of the impact fee is based on the quantity (flow) of wastewater generated. The occupants of the proposed OPSP shall pay the sanitary sewer fees imposed by the City of South San Francisco in order to mitigate the cost of the sewer system upgrades necessary to manage the wastewater flows generated by the OPSP. An additional 700 feet of 8-inch diameter sewer trunk from Eccles Avenue to Gull Road needs to be upsized to a 12-inch diameter trunk sewer. This segment of sewer trunk was not included in the recommendations in the Sewer Master Plan. The applicants shall either work with the City to include this improvement in an Sewer Master Plan update or directly fund their fair share of the improvement. The improvements specified in the Sewer Master Plan call for the Oyster Point Subtrunk to be increased from Pump Station No. 2 to the intersection of Oyster Point Boulevard and Eccles Avenue. The improvement calls for a new 18-inch diameter pipe to replace the existing 12-inch sewer that continues northward on Gateway Boulevard from Pump Station No. 2. The portion that continues eastward along Oyster Point Boulevard from Gateway Boulevard consists of a new 15-inch diameter sewer to replace existing 10-inch and 12-inch diameter sewers. A new 12-inch diameter section is needed to replace approximately 800 feet of existing 8-inch diameter sewer trunk to the intersection of Oyster Point Boulevard and Eccles Avenue. With the Sewer Master Plan improvements and the additional 800 feet from Eccles Avenue to Gull Road identified in Mitigation Measures Util-2a and -2b, impacts related to sewer trunk capacity would be reduced to less than significant. Note that there are geology/soils considerations related to utilities. These are discussed and addressed in Chapter 9: Geology, including the potential for hazardous soil or vapor conditions in the vicinity of the landfill (Impact Geo-9 and Mitigation Measures Geo-9a through 9c), the potential for differential settlement throughout the area causing stresses at utility/building connections and in utility lines and the potential for disruption of the flow gradient (Impacts and Mitigation Measures Geo-11, Geo-12 and Geo-13, respectively), and the need to maintain continuity of the landfill cap when working in the DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 17-12 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT vicinity of the landfill (Impact and Mitigation Measure Geo-10). These potential utility-related geology/soils impacts can be mitigated to a level of less than significant through implementation of the recommended mitigation measures. Wastewater Treatment Impact Util-3: Increased Wastewater Treatment Demand. Build-out of the OPSP area would increase wastewater flows and increase demand at the South San Francisco-San Bruno Water Quality Control Plant. However, according to the South San Francisco/San Bruno Water Quality Control Plant Draft Facilities Plan Update, there is sufficient capacity through the year 2030, including a reserve capacity for flows from the East of 101 area. As the wastewater treatment plant has adequate capacity to serve the OPSP’s projected demand, this increased demand is a less- than-significant impact. As discussed earlier, the OPSP will increase the average dry weather flow by 0.28 mgd and the peak flow by 0.61 mgd. The City is currently updating the WQCP facilities plan to evaluate the existing and future treatment capacity needs. Carollo Engineers issued a draft Facilities Plan report (Draft Facilities Plan) in April 2010. The Draft Facilities Plan estimates average flow projections through the year 2040 to reach 10.3 mgd, which is lower than the existing average dry weather plant capacity of 13 mgd. The increase of flow is within the project flows for the East of 101 area. Based on the findings from the Draft Facilities Plan, the increased flows from the OPSP will have a less than significant impact on the WQCP. Mitigation Measure: None INCREASE IN STORMWATER FLOWS Impact Util-4: Increased Impervious Area. OPSP area build-out will increase the impervious area by two acres, or 2.6 percent, which could result in increased stormwater flows and/or runoff not meeting treatment requirements, without appropriate on-site controls. However, the potential for increased flows will be mitigated through required compliance with the NPDES permit process, which will require such controls. Additionally, stormwater controls are proposed to meet or exceed LEED standards. The OPSP would not require additional off-site storm water facilities or fail to meet treatment requirements. This is a less-than-significant impact. The volume of stormwater is directly related to the amount of impervious area within a development. The percentage of impervious surfaces from developing the Phase I Project will slightly decrease from 46 percent impervious to 37 percent impervious. According to current conceptual plans, after build-out of the OPSP, the percentage of impervious area will slightly increase. The existing development is 56.7 percent impervious, while the OPSP is estimated to be 59.3 percent impervious. This increase will cause a slight increase in stormwater flows. Table 17.3 summarizes the changes to the pervious and impervious areas as a result of the Phase I Project and the initial infrastructure construction than as a result of build-out of the entire OPSP area. Figures 13 and 14 in Appendix G graphically show the pervious and impervious areas for the Phase I Project and the entire OPSP area respectively. Based on these results, the construction of the Phase I Project will not have an impact on the storm drainage system. CHAPTER 17: UTILITIES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 17-13 Table 17.3: Net Change in Impervious Area Stormwater runoff is regulated by the City’s National Pollution Discharge Elimination System (NPDES) permit. The City’s NPDES Permit specifies that redevelopment projects are subject to Provision C3. Provision C3 requires the permit holder to use its planning authority to impose best management practices on new developments or redevelopment projects. The practices include: •source controls, •stormwater treatment measures to address both soluble and insoluble pollution discharges, •limit runoff flows from new developments and redevelopment projects, •site design measures, Site design measures include: •low impact development (LID) techniques, •post construction stormwater site design treatment controls (for example; directing runoff to vegetative areas, vegetative swales, tree wells or bioretention gardens), •minimizing land disturbances, •clustering of structures and pavement, •use of micro detention, including landscape based detention, •preservation of open space, and •protection and/or restoration of riparian areas and wetlands as project amenities. Because the OPSP does not significantly increase the impervious area and post-construction stormwater treatment and LID site design measures will be required by the NPDES permit, the OPSP is not expected to significantly impact to the storm drainage system. Note that there are geology/soils considerations related to utilities. These are discussed and addressed in Chapter 9: Geology, including the potential for hazardous soil or vapor conditions in the vicinity of DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 17-14 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT the landfill (Impact Geo-9 and Mitigation Measures Geo-9a through 9c), the potential for differential settlement throughout the area causing stresses at utility/building connections and in utility lines and the potential for disruption of the flow gradient (Impacts and Mitigation Measures Geo-11, Geo-12 and Geo-13, respectively), and the need to maintain continuity of the landfill cap when working in the vicinity of the landfill (Impact and Mitigation Measure Geo-10). These potential utility-related geology/soils impacts can be mitigated to a level of less than significant through implementation of the recommended mitigation measures. LANDFILL CAPACITY Impact Util-5: Increased Solid Waste Disposal Demand. The OPSP would increase solid waste generation at the site but would be served by a landfill with sufficient permitted capacity to accommodate the OPSP’s solid waste disposal needs, and would not impede the ability of the City to meet the applicable federal, state and local statutes and regulations related to solid waste. The OPSP would have a less-than- significant impact with no mitigation warranted. As discussed in the setting section of this chapter, the Scavenger Company is contracted by the City of South San Francisco as the sole hauler of solid waste and operator of recycling services for the City. The Scavenger Company transports all solid waste from the OPSP area to the Blue Line Transfer facility. The Blue Line Transfer facility has a permitted capacity of 2,400 tons per day. Once the useable materials have been separated at the Blue Line Transfer facility, the remaining trash is then transported to the Ox Mountain Sanitary Landfill. The landfill has a permitted maximum disposal of 3,598 tons per day. The proposed OPSP would increase the amount of development at the site, resulting in an increase of solid waste to the Blue Line Transfer facility and Ox Mountain Sanitary Landfill from the OPSP area. Development under the proposed OPSP would result in an additional 3,610 tons of solid waste per year (approximately 9.88 tons per day)6, representing less than 1 percent of the permitted maximum amount accepted daily at the Blue Line Transfer facility and Ox Mountain Sanitary Landfill (approximately 0.41 percent and 0.27 percent respectively). The remaining capacity of the Blue Line Transfer facility would be able to accommodate the additional solid waste. While the Ox Mountain landfill is currently in excess of its originally permitted capacity, they are permitted until 2018 to expand the Ox Mountain landfill and continue to accept waste as the landfill gradually settles and new space becomes available. As discussed previously, the operators would either further expand Corinda Los Trancos or open Apanolio Canyon for fill to ensure adequate available capacity after 2018. Thus, the increase in solid waste generated under the proposed OPSP would be sufficiently served by the Blue Line Transfer facility and the Ox Mountain Landfill. Therefore, the impact would be less than significant and no mitigation measures are required. Solid waste disposal and recycling in the City of South San Francisco is regulated by the City’s SSFMC, particularly Chapters 8.16 and 8.28. As neither of these chapters establishes quantitative disposal or recycling rates, the OPSP site would not be subject to diversion requirements. However, under the SSFMC, the project would be required to have its solid waste, including construction and 6 A rule of thumb of a solid waste generation rate of 0.0108 pounds per square foot per day was applied to the existing and proposed development to generate estimates of net waste generation. This factor comes originally from Guidelines for Preparation of Environmental Assessments for Solid Waste Impacts, Ventura County Solid Waste Management Department, May 1998. CHAPTER 17: UTILITIES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 17-15 demolition debris, and recyclable materials collected by the Scavenger Company. Additional health and sanitation requirements set forth in the SSFMC would be met by the Scavenger Company. As described in the Regulatory Framework, AB 939 requires that local jurisdictions divert at least 50 percent of all solid waste by 2000. Prior to 2004, the City of South San Francisco was not been able to meet the AB 939 requirement. However, the CIWMB has repeatedly granted the City time extensions to achieve the 50 percent diversion goal. Between 2004 and 2006, the City met the AB 939 requirement. As analyzed above, the OPSP area is not a substantial contributor to the City’s generation of solid waste disposal at the Ox Mountain Sanitary Landfill. Implementation of the proposed OPSP would increase the OPSP area’s solid waste contribution by less than 1 percent to the Blue Line Transfer facility and Ox Mountain Sanitary Landfill. Consequently, because the proposed OPSP would not impede the City’s compliance with AB 939, the impact related to compliance with solid waste regulations would be less than significant and no mitigation measures are required. ENERGY The OPSP would be considered to have a significant impact related to energy use if it would violate applicable federal, state and local statutes and regulations relating to energy standards and/or if energy consumption increases resulting from the OPSP would trigger the need or expanded off-site energy facilities. Impact Util-6: Increased Energy Consumption. The OPSP would have an incremental increase in the demand for gas and electrical power given the increase in development in the OPSP area. However, the OPSP is expected to be served with existing capacity and would not require or result in construction of new energy facilities or expansion of existing off-site facilities and would not violate applicable federal, state and local statutes and regulations relating to energy standards. Additionally, buildings in the OPSP are proposed to meet or exceed LEED standards. The OPSP would have a less-than-significant impact relating to energy consumption with no mitigation warranted. The OPSP would be required by the City to comply with all standards of Title 24 of the California Code of Regulations and the new California Green Building Standards Code (CALGREEN), as applicable, aimed at the incorporation of energy-conserving design and construction. PG&E infrastructure exists on the OPSP site, and any improvements and extensions required to accommodate the OPSP would be determined in consultation with PG&E prior to installation. As a result, although the OPSP would incrementally increase energy consumption, it would not result in a significant impact related to the provision of energy services. CUMULATIVE UTILITIES IMPACTS The geographic context for a discussion of cumulative impacts to utilities is the service area of the utility in question. For instance, the geographic context for cumulative impacts to water supply is the CWSC and SFPUC service areas; to wastewater, it is the East of 101 Area; and to the storm drainage system, the geographic context is the local watershed. The cumulative impacts analysis for each utility includes all cumulative growth within its respective service area, as identified by the providers’ demand projections. The surplus SFPUC supply identified under the analysis above takes into account assumed cumulative increases in system-wide water demand and would accommodate anticipated development in the area DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 17-16 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT including the OPSP. This assumes increased demand management and/or conservation system-wide over time. The cumulative impact related to water supply would be less-than significant. The existing drainage system in the East of 101 Area is generally designed and constructed for industrial development, which has a high ratio of impervious surfaces. Stormwater point and non-point source discharges are a major source of pollution in San Francisco Bay from the City, as the City’s storm drainage system discharges to the Bay. As redevelopment in the East of 101 Area continues, development could degrade water quality through industrial/R&D pollutant discharges or simply as a result of increased traffic. To combat this problem, the San Mateo County Stormwater Pollution Prevention Program (STOPPP) has prepared a Best Management Practices plan to control pollutants in their stormwater system. Compliance with the permit requirements for non-point source stormwater discharge under the NPDES also requires the property owner of all construction projects over one acre in size to obtain a stormwater discharge permit. The storm water system consists of a variety of disconnected drainage systems, including surface street drainage, and underground storm drains that drain to numerous outfalls that discharge to the San Francisco Bay (Bay) along the north, west, and eastern sides of Oyster Point. Stormwater flow from the outfalls is not treated. The developer has proposed to connect to the existing underground drainage network at several locations, and the existing outfalls will continue to be used with modifications to comply with BMPs. According to the OPSP, stormwater treatment and controls will be designed in conformance with the use of Best Management Practices (BMPs), and LID practices such as vegetated swales, vegetative buffer strips, media filters, and bioretention areas per the requirements of Provision C3 of the City’s NPDES permit. The WQCP operates under STOPPP’s Joint Municipal NPDES Permit. Cumulative impact and redevelopment may result in a significant increase of pollutant load in the runoff. The proposed project represents 81 acres or approximately 4.8 percent of the 1,700 acres in the East of 101 Area. Therefore, the proposed project would not be cumulatively considerable. Additionally, compliance with NPDES will ensure project-specific and cumulative impacts will be further reduced. The Sewer Master Plan required sewer system upgrades and allocated construction costs to existing and future users. The OPSP will increase the average dry weather flow by 0.28 mgd and the peak flow by 0.61 mgd. The City is currently updating the WQCP facilities plan to evaluate the existing and future treatment capacity needs. Carollo Engineers issued a draft Facilities Plan report (Draft Facilities Plan) in April 2010. The Draft Facilities Plan estimates average flow projections through the year 2040 to reach 10.3 mgd, which is lower than the existing average dry weather plant capacity of 13 mgd. The increase of flow is within the project flows for the East of 101 area and the cumulative impact is less than significant. Deficiencies in the collection system identified in Sewer Master Plan still need to be implemented to provide for future capacity. Specific to the OPSP, the improvements specified in the Sewer Master Plan call for Pump Station No. 2 to be upgraded with a larger capacity and the Oyster Point Subtrunk to be increased. (There is an additional 800 feet that would need to be upgraded that is not currently included in the Sewer Master Plan.) Through Mitigation Measures Util-1a and 1b and payment of connection fees that will go toward area improvements, the collection system in the vicinity will adequately the serve the cumulative growth, the impact to the collection systems is less than significant. OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 18-1 18 OTHER CEQA CONSIDERATIONS INTRODUCTION This chapter of the Draft EIR contains discussion of the following additional CEQA considerations: x Significant Irreversible Modifications In The Environment x Growth Inducing Impacts x Cumulative Impacts SIGNIFICANT IRREVERSIBLE MODIFICATIONS IN THE ENVIRONMENT An EIR must identify any significant irreversible environmental changes that could be caused by a project. These may include current or future uses of non-renewable resources, and secondary or growth-inducing impacts that commit future generations to similar uses. Irretrievable commitments of resources should be evaluated to assure that such current consumption is justified. The CEQA Guidelines describe three distinct categories of significant irreversible changes: 1) changes in land use which would commit future generations to specific uses; 2) irreversible changes from environmental actions; and 3) consumption of non-renewable resources. Changes in Land Use Which Would Commit Future Generations The OPSP would modify the mix of land uses in the OPSP area consistent with the evolving character of the East of 101 area. Office/R&D uses would be intensified, light industrial uses would be replaced, the hotel use would be intensified, and supporting commercial uses would be allowed. All of these changes are consistent with plans and policies for development of the area and region. Irreversible Changes from Environmental Actions Irreversible changes to the physical environment could stem from the accidental release of hazardous materials associated with development and/or on-going use of the site as a research facility. However, compliance with hazardous materials regulations and policies as outlined in Chapter 11 of this document, Hazardous Materials, is expected to maintain this potential impact at a less-than-significant level. Consumption of Nonrenewable Resources Consumption of nonrenewable resources includes increased energy consumption, conversion of agricultural lands, and lost access to mining reserves. The OPSP would not result in the loss of agricultural lands or mining reserves. The OPSP would result in the consumption of some nonrenewable resources during construction and operation, such as electricity and construction materials. While this would require additional energy of several types for construction and on-going DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 18-2 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT use, it would not require the construction of major new lines to deliver energy, and it is anticipated service providers can provide the capacity to serve the OPSP with existing infrastructure. Development of the OPSP area as proposed could result in the commitment of nonrenewable resources (e.g., gravel and petroleum products) and slowly renewable resources (e.g., wood products) used in construction. The operation of the proposed uses would also require further commitment of water and energy resources (e.g., petroleum products for vehicle operations, natural gas and electricity for lighting, heating, and cooling). Although the OPSP would result in the irreversible commitment of resources, these are weighed against the appropriateness of the location for such development with access to transit and views and the benefits of additional employment, revenue and recreation opportunities. GROWTH INDUCING IMPACTS The OPSP would not be expected to result in a direct increase in the local population, since it would not result in the construction of any new housing units. The OPSP area is located at a terminus, with the Bay on both the north and east sides and it is therefore not anticipated that infrastructure improvements for this area would be used to support substantial additional growth in surrounding areas. Indirect increases in population due to greater employment opportunities are discussed in more detail under Population/Housing section in Chapter 15 and found to be less than significant. CUMULATIVE IMPACTS As defined in Section 15355 of the CEQA Guidelines, a cumulative impact consists of an impact which is created as a result of the combination of the OPSP evaluated in the EIR together with other projects causing related impacts. “Cumulative impacts” refer to two or more individual effects which, when considered together, are considerable or which compound or increase other environmental impacts. The cumulative impact from several projects is the change in the environment that results from the incremental impact of the project when added to other closely related past, present and reasonably foreseeable probable future projects. Cumulative impacts can result from individually minor but collectively significant projects taking place over a period of time. The potential for cumulative impacts are discussed in the analysis chapters 4 through 17 of this document. In summary, development of the OPSP site as proposed would contribute to a cumulative increase in impacts in areas such as Air Quality, Greenhouse Gas Emissions, Geology and Soils, Hazardous Materials, Hydrology, Noise, Transportation/Traffic and Utilities. However, the OPSP’s contribution to these cumulative effects would be less-than-significant or would be reduced to a level of less than cumulatively considerable through implementation of any project-specific mitigation measures for all except the following items, which would be significant and unavoidable on a cumulative level. x Air Quality: Inconsistency with the Clean Air Plan related to increases in vehicles miles traveled greater than increases in city-wide population and General Plan assumptions for the site. x Greenhouse Gas Emissions: Emissions of greenhouse gasses that would be above the Air District’s 2010 thresholds. As described in Chapter 10, these thresholds do not apply to this analysis because this EIR was commenced prior to the effective date of these thresholds. x Traffic: Declines in operation of and unacceptable queuing at U.S. 101 ramps and/or intersections serving them as well as the mainline U.S. 101. OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 19-1 19 ALTERNATIVES INTRODUCTION The California Environmental Quality Act Guidelines (CEQA Guidelines, 1970, as amended, Section 15126.6) require an EIR to include a discussion of a reasonable range of alternatives to the proposed project. The CEQA Guidelines also require that the EIR explain why specific project alternatives considered at one time were rejected in favor of the proposed project. The selection of alternatives is to be guided by the provision of reasonable choices and the promotion of informed decision making and informed public participation. An EIR need not evaluate alternatives that would have effects that cannot be determined, or for which implementation would be remote and speculative. The Guidelines also require that the EIR specifically evaluate a “no project” alternative within this discussion and that an “environmentally superior” alternative be identified (Section 15126.6 [e]). The alternatives addressed in this EIR were selected based on the following factors: 1.The extent to which the alternative would accomplish most of the basic project objectives 2.The extent to which the alternative would avoid or lessen any of the identified significant environmental effects of the project (discussed in Chapters 4 through 18) 3.The potential feasibility of the alternative (as discussed in this Chapter) 4.The extent to which the alternative contributes to a “reasonable range” of alternatives necessary to permit a reasoned choice The proposed OPSP and Phase I Project are fully described in Chapter 3 of this EIR (Project Description). The environmental consequences are addressed in Chapters 4 through 18 of this EIR. OPSP OBJECTIVES CEQA requires the analysis of alternatives that would feasibly attain “most of the basic objectives of the project but would avoid or substantially lessen any of the significant effects of the project.”1 Therefore, the stated objectives can be used as a metric against which an alternative can be measured when determining overall feasibility.2 Additionally, CEQA requires the evaluation of a proposed project to address only impacts to the physical environment; economic and social effects can be analyzed only as one link in a chain of cause and effect from a proposed decision (e.g., physical 1 CEQA Guidelines, Section 15126.6 (a) 2 Ibid., Section 15126.6 (a) DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 19-2 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT changes caused, in turn, buy economic and social changes).3 However, economic viability can be considered when determining the feasibility of a project alternative.4 The following are applicant and city objectives that are fulfilled by the proposed OPSP (also outlined on page 3-2 of this document). Alternatives will be evaluated in part based on their ability to meet these objectives. 1.Create a vibrant destination and a new gateway to the City of South San Francisco. 2.Reorganize the area into a better pattern of land uses that will benefit all of the community’s stakeholders. 3.Provide quality research and development facilities consistent with the General Plan designation as a site for business and technology park facilities. 4.Continue to develop the East of 101 area into a nationally recognized research and development center that will attract other life science and high technology businesses. 5.Enhance availability of public open space and access to the Bay. 6.Provide flexible recreational amenities for public use. 7.Repair and upgrade the landfill closure to Title 27 standards. 8.To counteract the potential effects of sea level rise on the closed landfill and public and surrounding property. 9.Untangle the various ground leases and land uses that has prohibited the City from realizing its vision for a coherent mixture of public and private land uses on Oyster Point. 10.Redevelop under-utilized land. 11.Reconfigure existing roads to enhance view corridors to the Bay and accommodate a more efficient layout of development sites. 12.Generate additional demand for the transit mode-shift opportunities inherent in proximity to the upcoming ferry terminal. 13.Build a project that creates quality jobs for South San Francisco. 14.Generate net property tax and other fees from the development project and enhance property values. 15.Build a project that is viable in the East of 101 area based upon market conditions and projected service requirements for the area. 16.Develop a project of high quality design as called for in the Design Element of the East of 101 area Plan and which integrates with adjoining properties. 17.Allow for use of redevelopment tax increment and debt to help ensure fiscal feasibility of this and other redevelopment area projects. 3 Ibid., Section 15131. 4 Ibid., Section 15126.6(f)(1). CHAPTER 19: ALTERNATIVES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 19-3 OPSP IMPACTS The OPSP would not result in significant impacts to agricultural and forest resources, construction- period greenhouse gas emissions, land use and planning, mineral resources, population and housing, public services, or recreation. Impacts associated with the following topics would be significant without the implementation of mitigation measures, but would be reduced to a less-than-significant level if the mitigation measures recommended in this EIR are implemented. Aesthetics Air Quality Biological Resources Cultural Resources Geology and Soils Hazards and Hazardous Materials Hydrology Noise Transportation and Circulation Utilities and Service Systems Based on the analysis contained in this Draft EIR, implementation of the OPSP would result in significant and unavoidable impacts to the following: x Air Quality: Inconsistency with the Clean Air Plan related to increases in vehicles miles traveled greater than increases in city-wide population and General Plan assumptions for the site. x Greenhouse Gas Emissions: Operational emissions of greenhouse gasses that would be above the Air District’s 2010 thresholds. As described in Chapter 10, these thresholds do not apply to this analysis because this EIR was commenced prior to the effective date of these thresholds. x Noise: Construction-period noise at on-site live-aboard boats over an extended period. x Traffic: Declines in operation of and unacceptable queuing at U.S. 101 ramps and/or intersections serving them as well as the mainline U.S. 101. ALTERNATIVES ANALYSIS The alternatives analysis is presented as a comparative analysis to the proposed OPSP. A project may have the potential to generate significant impacts, but changes to certain features may also afford the opportunity to avoid or reduce such impacts. The following alternatives analysis compares the potential significant environmental impacts of the alternatives with those of the proposed OPSP for each of the environmental topics analyzed in detail in Chapters 4 through 18 of the EIR and discusses feasibility of implementation, and ability to meet objectives. SELECTION OF ALTERNATIVES Three alternatives were evaluated. All of the alternatives are located on the OPSP site. Differences between the alternatives focus on square footage of development. The three alternatives to be analyzed DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 19-4 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT in comparison to the proposed OPSP are shown in Table 19.1 at the end of this chapter and are as follows: Alternative A: No Project/No Redevelopment Alternative. Alternative A is a “no project” alternative. It assumes the proposed OPSP is not approved and the existing uses remain on the site, and are not redeveloped at higher density. As the only currently vacant area, the portion of the OPSP area to the south of Oyster Point Boulevard and east of Gull Road would reasonably be expected to be developed even without approval of the OPSP. For this analysis, it has been assumed this area would be developed with uses similar to the existing Oyster Point Business Park, consisting of a single-story office/light industrial building of approximately 65,000 square feet. This Alternative assumes no other development and no roadway, recreational, or landfill cap improvements. This alternative satisfies the CEQA requirement to evaluate a “No Project” alternative, which means “the existing conditions, as well as what would reasonably be expected to occur in the foreseeable future if the project were not approved, based on current plans and consistent with available infrastructure and community services” (CEQA Guidelines, Section 15126.6[e][2]). While the Guidelines allow the no project alternative to assess development under the continuation of the existing plan, policy, or operation into the future, the site is currently developed as a office/light industrial business park and while it is possible the site will be redeveloped at some future point even if a project does not proceed at this time, there is no reason to believe this would happen in the near-term or that new development would necessarily be more dense than the existing development. Therefore, Alternative A presumes the site would remain largely in its current state. Alternative B: Reduced Intensity (FAR 1.0) Alternative. Alternative B would allow redevelopment of the OPSP site at an FAR of 1.0 for office/R&D uses. This alternative assumes the same area for office/R&D uses with the same 40/60 split between office and R&D development and similar phasing and parking ratio. The remainder of development, i.e., hotel and recreation fields, would remain the same as that proposed under the OPSP. This alternative would result in the construction of approximately 714,400 square feet of office uses and 1,071,600 square feet of R&D uses, for a total of 1,786,000 square feet of office/R&D development. Buildout under Alternative B would result in approximately 5,000 office/R&D employees on the OPSP site (1,440 less than under the proposed OPSP). Alternative C: Reduced Intensity (FAR 1.12) Alternative. Alternative C would allow redevelopment of the OPSP site at an FAR of 1.12 for the office/R&D areas, with no change to the other planned development (hotel, recreation fields). This alternative assumes the same area for office/R&D uses with the same 40/60 split between office and R&D development and similar phasing and parking ratio. This alternative would result in the construction of approximately 800,110 square feet of office uses and 1,200,165 square feet of R&D uses, for a total of 2,000,275 square feet of office/R&D development. Buildout under Alternative C would result in approximately 5,600 office/R&D employees on the OPSP site (840 less than under the proposed OPSP). Alternatives Rejected as Infeasible As described above, Section 15126.6(c) of the CEQA Guidelines requires an EIR to identify any alternatives that were considered by the lead agency but were rejected as infeasible during the scoping process and briefly explain the reasons underlying the lead agency’s determination. Given the nature of the project (a Specific Plan for a specific site), the fact that the project applicant owns this site and does not intend to develop these uses in another place, an off-site alternative was not feasible. Also, because the types of uses proposed are allowed under the existing General Plan designation for the site, and because the OPSP is compliant with TDM program trip reductions and reduced parking levels, only CHAPTER 19: ALTERNATIVES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 19-5 development intensity was targeted as a parameter that could be changed to affect impacts. Two reduced intensity alternatives were analyzed, office/R&D development at a FAR of 1.0 and Alternative C, with an FAR half-way between that and the proposed FAR of 1.25, at 1.12, with a reasonable expectation that this reduction could reduce known significant and unavoidable impacts. ALTERNATIVE A: NO PROJECT/NO REDEVELOPMENT ALTERNATIVE Impact Analysis The impact analysis below focuses on those impacts that were determined to be potentially significant under the proposed OPSP. Less than significant impacts are generally discussed only if implementation of the alternative will substantially increase the impact. Impact Summary The No Project Alternative would involve only limited changes to the existing development at the OPSP site and so only a limited potential for environmental impacts. The impacts of the existing uses are consistent with the baseline for evaluation of this EIR, and are therefore not considered new impacts. The only new impacts would result from the development of the currently vacant parcel at the southeast corner of Oyster Point Boulevard and Gull Drive. However, this Alternative would not involve improvements to the roadways or upgrading of the landfill cap and would not involve development of a recreational area and waterfront open space. As discussed below, the majority of impacts would be substantially reduced under this Alternative, including the avoidance of all Significant and Unavoidable impacts identified under the proposed OPSP, which are related to conflict with the Clean Air Plan, construction noise and traffic congestion. Aesthetics The already less-than-significant impact related to partial blockage of scenic views from public and private locations both on and off site would be anticipated to be substantially reduced, as this Alternative includes only one additional single-story building, which would not be located at the shoreline and would not be anticipated to substantially impact any views. Lighting and building materials on the site under Alternative A would be anticipated to be similar to existing uses and would be subject to the same City standards as the proposed OPSP. Air Quality and Greenhouse Gas Emissions Because this Alternative would result in fewer vehicle trips to the site than the proposed OPSP as well as less building space that would require water and use energy, air quality impacts and greenhouse gas emissions would be roughly 95% less than those identified under the proposed OPSP. Based on BAAQMD screening levels (121,000 square feet of light industrial uses and 50,000 square feet of office), greenhouse gas emissions for Alternative A would be anticipated to be below the threshold of significance and therefore replace the significant and unavoidable impact identified under the proposed OPSP with a less than significant impact under Alternative A. Because of this significantly reduced level of traffic and emissions that are below even those assumed under the General Plan, this alternative would avoid the Significant and Unavoidable impact related to conflict with the Clean Air Plan identified for the proposed OPSP. The substantially lower amount of construction under Alternative A would equate to substantially lower construction-period emissions, though BAAQMD standard construction measures would be required to reduce the impact to less than significant and BAAQMD-recommended construction DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 19-6 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT greenhouse gas reduction measures would be implemented to further reduce impacts, as under the proposed OPSP. It can be assumed that no auxiliary uses would be developed under this Alternative, so unlike under the proposed OPSP, there would be no impacts related to bringing sensitive users to the site. As this Alternative would involve substantially less disruption of the landfill materials, it is assumed that already less than significant odor impacts would be further reduced. Biological Resources Development under Alternative A would disturb substantially less area than the proposed OPSP. While impacts related to loss of sensitive habitat is already less than significant, it would be much reduced. It is assumed no Bay Trail improvements or in-water construction would occur under this Alternative, so impacts related to wetland or aquatic habitats or species would be fully avoided, except that compliance with NPDES requirements and best management practices would still be required to ensure construction-period runoff would not impact wetland or water environments. While burrowing owls were not found on the site, they could take up residence prior to construction, under either the proposed OPSP or Alternative A. Additionally, most nesting birds are protected under the by the Migratory Bird Treaty Act of 1918 and/or Fish and Game Code of California. Nesting birds or burrowing owls could be disturbed by construction activities. The impacts would be substantially reduced because of the smaller area to be disturbed under Alternative A, but would require pre- construction surveys with appropriate mitigation if nesting birds or burrowing owls are found to ensure these impacts are less than significant. Because the exact layout under Alternative A is not known, it is assumed that potential impacts related to stormwater outfall and the wetlands/tidal channel on the southwestern part of the site would be similar to those under proposed OPSP and could be mitigated through assurance of adequate capacity and maintenance of the stormwater system. Geology and Soils The Bay Area is a seismically active region, so the potential for subjecting people or structures to ground shaking, seismic-related ground failure and/or failure of the perimeter dikes exists under both the proposed OPSP or Alternative A and would require compliance with applicable regulations and design-level geotechnical investigation. However, because development intensity would be reduced under Alternative A, and therefore would result in less structures and people, the impact would also be marginally reduced. Impacts related to variable subsurface conditions including Bay Mud, landfill waste and other fill including settlement and gas accumulation would be substantially reduced under Alternative A and would still require specific construction techniques and structural elements to reduce the impacts to less than significant. Because of the substantially smaller area to be disturbed during construction, impacts related to construction-period disturbance of soil and erosion would be substantially reduced, though still require implementation of a Storm Water Pollution Prevention Plan. CHAPTER 19: ALTERNATIVES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 19-7 Hazards and Hazardous Materials While the new building included in Alternative A would likely handle some materials considered to be biological hazards, chemical hazards and/or carry a risk of fire or explosion, which pose a risk of accidental upset and environmental contamination from routine transport, storage, use and disposal, the much reduced intensity of development coupled with the likely use for office/light industrial as opposed to research and development, would substantially reduce this risk compared to the proposed OPSP. If applicable, development under Alternative A would need to demonstrate compliance with existing regulations, plans and programs. Impacts related to construction such as fugitive contaminated dust during grading and construction and potential contact with contaminated landfill materials/gasses and groundwater during construction as well as ongoing maintenance activities would remain, but be much reduced under Alternative A due to the substantially reduced building area, area of disturbance during construction as well avoiding the need for demolition of any structures. Under either the proposed OPSP or Alternative A, buildings will meet height limits set for safety under the Airport Land Use Plan for the nearby San Francisco International Airport. The subject site is not in an area subject to wildfires and the proposed development will not interfere with an adopted emergency response plan. These impacts would be the same under the proposed OPSP or Alternative A. Hydrology Proposed development in the vicinity of the landfill poses a risk of off-site migration of leachate. This impact will be reduced through use of BMPs during installation of foundation piers, landfill cap upgrades, and continued monitoring for leachate migration during operation and maintenance. Under Alternative A, construction in the vicinity of the landfill and resultant impacts would be substantially reduced compared to the proposed OPSP. Again, because the proposed square footage, construction activities and disturbed area would be substantially reduced under Alternative A, impacts to construction-period and operational hydrology and water quality would be substantially reduces from those described for the proposed OPSP and would be less than significant with mitigation. Land Use and Planning Similar to the proposed OPSP, Alternative A would not result in any significant land use impacts. It would not divide an established community, would not conflict with plans and policies intended to avoid or mitigate an environmental effect, and would not conflict with a conservation plan. Noise Because only one building is proposed under Alternative A, it is expected that the construction phase would be substantially shortened, thereby decreasing the duration of construction-related noise in the OPSP area and resulting in substantially reduced construction-related noise impacts compared to those described for the proposed OPSP. The impact would be considered less than significant with mitigation under Alternative A, whereas it was Significant and Unavoidable under the extended construction period of the proposed OPSP. Because of the reduced intensity of development and lower levels of resultant traffic, increases in noise at and in the vicinity of the site would be substantially less under Alternative A than under the proposed OPSP. These impacts are less than significant under either scenario. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 19-8 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Transportation and Circulation Alternative A would result in new vehicle trips in the vicinity, but with substantially less development proposed, these would equate to only about 5% of the trip generation assumed under the proposed OPSP. The number of trips generated under this Alternative would likely still result in an increase over the threshold of 100 new vehicle trips, triggering the requirement of a TDM Plan. These substantially reduced traffic levels would avoid significant and unavoidable impacts related to declines in operation of and unacceptable queuing at U.S. 101 ramps and/or intersections serving them or on the U.S. 101 mainline to less than significant levels, as the contribution of traffic under Alternative A would likely be below levels that would be cumulatively considerable. While the exact layout under Alternative A is not known, it is assumed the one parcel that would be developed would be designed to avoid potential impacts related to pedestrian/vehicle conflict. Utilities and Service Systems Because only a limited new square footage is proposed under Alternative A, there would not be substantial increased demand for utilities from the existing condition. Alternative A would still be required to comply with applicable regulations and pay applicable connection fees, but would not require the upgrade of sewer system improvements beyond that anticipated to be paid for through connection fees. Ability to Accomplish OPSP Objectives and Feasibility Alternative A would not support many of the project objectives, and those it would, only to a substantially lesser degree than would the OPSP. By developing only the currently vacant parcel and not redeveloping any of the existing uses, development intensity would be reduced by approximately 95% and all of the project objectives would be seriously compromised, including: x The site would not be transformed into a gateway and underutilized land would not be redeveloped. x There would be substantially fewer jobs created during the construction and operation of the development and substantially fewer employees that would be potential Ferry users brought to the site. x Reorganizing the land use pattern and redeveloping underutilized land will be less feasible because substantially less tax increment will be generated and there would be substantially less value in the private redevelopment to support public infrastructure and community benefits through a community facilities district; x The quality of development and jobs in the area would not be substantially enhanced, nor would the collection of taxes and fees. x This alternative would not create new recreational space or provide for landfill cover repair or protection from sea level rise. While economically feasible as described, Alternative A does not propose needed upgrades to the landfill site or upgrades to utilities and infrastructure and the environmental mitigation that would be required to do so. It is uncertain how such improvements would be made under Alternative A. CHAPTER 19: ALTERNATIVES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 19-9 ALTERNATIVE B: REDUCED INTENSITY (FAR 1.0) ALTERNATIVE Impact Analysis The impact analysis below focuses on those impacts that were determined to be potentially significant under the proposed OPSP. Less than significant impacts are generally discussed only if implementation of the alternative will substantially increase the impact. Impact Summary Reducing the allowable office/R&D development to that which is currently allowed under the General Plan (i.e., a reduction of approximately 20%) would primarily reduce impacts related to vehicle trips and to some degree construction-period impacts, such as air quality emissions, traffic and noise. Alternative B would also avoid the new Significant and Unavoidable impact due to the conflict regarding assumptions in the Clean Air Plan related to growth in vehicles miles traveled versus population growth (Impact Air-1). While the growth in vehicles miles traveled would still be above that identified in the Clean Air Plan, Alternative B would be consistent with the General Plan, which already disclosed this inconsistency for development consistent with the General Plan. Therefore, no new impact would be identified related to conflict with the Clean Air Plan. However, Alternative B would not, as discussed below, result in the avoidance or lessening of any other significant and unavoidable impacts to a less than significant level. Aesthetics Similar to the proposed OPSP, Alternative B would replace single story office/light industrial buildings with larger, modern office/R&D buildings and would have no adverse impact on visual character. The already less-than-significant impact related to partial blockage of scenic views from public and private locations both on and off site would be anticipated to be somewhat reduced due to less building mass on the site. Lighting and building materials on the site under Alternative B would be anticipated to be similar to the proposed OPSP and would be subject to the same City standards as the proposed OPSP. Air Quality and Greenhouse Gas Emissions Because this Alternative would result in fewer vehicle trips to the site than the proposed OPSP as well as less building space that would require water and use energy, air quality impacts and greenhouse gas emissions would be roughly 20% less than those identified under the proposed OPSP. This would marginally reduce the already less-than-significant air quality impacts that had been identified under the OPSP. However, because greenhouse gas emissions are compared against an efficiency-based threshold and the reduction in square footage and traffic emissions under Alternative B would go along with a reduction in employees on the site, it is anticipated that the significant and unavoidable greenhouse gas emissions impact identified for the OPSP would be the same under Alternative B. As with the proposed OPSP, operation of Alternative B would not be anticipated to create objectionable odors affecting a substantial number of people. While the exact layout of buildings under the reduced-intensity Alternative B is not known, less building space would equate to marginally lower construction-period emissions, though BAAQMD fugitive dust and emissions reduction measures would be required to reduce the impact to less than significant and BAAQMD-recommended construction greenhouse gas reduction measures would be implemented to further reduce impacts, as under the proposed OPSP. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 19-10 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT As with the proposed OPSP, any proposed auxiliary uses which would bring sensitive users to the site for long periods each day (such as a daycare facility) would require assessment of the health risk. This impact would be the same under Alternative B and the proposed OPSP. Because Alternative B would result in greater development intensity than existing on the site now, a Significant and Unavoidable impact related to increases in vehicles miles traveled above that assumed in the Clean Air Plan would remain, though it would be slightly reduced from that under the OPSP. Biological Resources While habitats in the OPSP area are generally not particularly sensitive, valuable (from the perspective of providing important wildlife habitat), or exemplary occurrences and would represent no substantial loss of foraging or non-breeding habitat for any special-status species, there is the possibility of impacting wetland or aquatic habitats and/or special-status species within them primarily through in- water construction related to replacement of up to two docks and work on the shoreline Bay Trail, both of which are proposed under either the OPSP or Alternative B, so the impact would be the same. These areas could additionally be impacted by sediment from construction-period runoff, though this would be similar under either the proposed OPSP or Alternative B and mitigated through minimizing near- water soil disturbance and incorporating best management practices. Again, because the exact layout under Alternative B is not known, it is assumed that potential impacts related to stormwater outfall and the wetlands/tidal channel on the southwestern part of the site would be similar to those under proposed OPSP and could be mitigated through assurance of adequate capacity and maintenance of the stormwater system. While burrowing owls were not found on the site, they could take up residence prior to construction, under either the proposed OPSP or Alternative B. Additionally, most nesting birds are protected under the by the Migratory Bird Treaty Act of 1918 and/or Fish and Game Code of California. Nesting birds or burrowing owls could be disturbed by construction activities. The impacts would be similar under either the proposed OPSP or Alternative B and would require pre-construction surveys with appropriate mitigation if nesting birds or burrowing owls are found to ensure these impacts are less than significant. Proposed buildings will project higher than existing structures, creating new, somewhat greater strike hazard for migrating and foraging birds. As the specifics of building design under Alternative B is not known, it is assumed impacts would be similar to the proposed OPSP and would require building design and lighting measures to minimize such impacts. Impacts would also be anticipated to be generally the same as under the proposed OPSP related to tree removal and increased lighting impacts and recreational disturbance on wildlife. Geology and Soils The Bay Area is a seismically active region, so the potential for subjecting people or structures to ground shaking, seismic-related ground failure and/or failure of the perimeter dikes exists under both the proposed OPSP or Alternative B and would require compliance with applicable regulations and design-level geotechnical investigation. However, because development intensity would be reduced under Alternative B, and therefore would result in less structures and people, the impact would also be marginally reduced. Again, impacts related to variable subsurface conditions including Bay Mud, landfill waste and other fill including settlement and gas accumulation would be similar under Alternative B as under the CHAPTER 19: ALTERNATIVES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 19-11 proposed OPSP and would require specific construction techniques and structural elements to reduce the impacts to less than significant. While the specifics of development under Alternative B are not known, it can be assumed the disturbed area would not substantially change and that impacts related to construction-period disturbance of soil and erosion would remain similar to that under the proposed OPSP and be able to be reduced to less than significant through implementation of a required Storm Water Pollution Prevention Plan. Hazards and Hazardous Materials While specific tenants have not yet been identified, research laboratories are likely to handle materials considered to be biological hazards, chemical hazards and/or carry a risk of fire or explosion, which pose a risk of accidental upset and environmental contamination from routine transport, storage, use and disposal. These impacts would be marginally reduced under Alternative B as compared to the proposed OPSP due to the fact that reduction in building size could be anticipated to reduce research and development activities on site with fewer employees and decreased use of hazardous materials. Under either the proposed OPSP or Alternative B, compliance with existing regulations, plans and programs would reduce the impact to less-than-significant. Similar to the proposed OPSP, this Alternative would result in impacts related to construction such as release of hazardous materials from structure materials during demolition, fugitive contaminated dust during grading and construction, and potential contact with contaminated landfill materials/gasses and groundwater during construction as well as ongoing maintenance activities. Additionally, the building loads on the landfill could result in off-site migration of leachate from the landfill. While the specifics of development under Alternative B are not known, it can be assumed the disturbed area would not substantially change and that impacts related to construction-period hazards would remain similar to that under the proposed OPSP and be able to be reduced to less than significant through implementation of a demolition plan and measures to avoid releases of wastes or waste water into the environment and to protect workers and the public during excavation and re-disposition of landfill material and design elements to mitigate the potential for accumulation of soil vapors. Under either the proposed OPSP or Alternative B, buildings will meet height limits set for safety under the Airport Land Use Plan for the nearby San Francisco International Airport. The subject site is not in an area subject to wildfires and the proposed development will not interfere with an adopted emergency response plan. These impacts would be the same under the proposed OPSP or Alternative B. Hydrology Proposed development in the vicinity of the landfill poses a risk of off-site migration of leachate as a result of modification of the landfill cap and underlying Bay Mud. This impact will be reduced through use of BMPs during installation of foundation piers, landfill cap upgrades, and continued monitoring for leachate migration during operation and maintenance. While the specifics of development under Alternative B are not known, it is assumed construction in the vicinity of the landfill would not substantially change and impacts could be similar as under the proposed OPSP. While the square footage of office/R&D uses under Alternative B would be reduced by approximately 20%, the area disturbed during construction and resultant building footprint would not necessarily be expected to substantially change. As a result, Alternative B would result in the same or similar impacts to construction-period and operational hydrology and water quality as those described for the proposed OPSP and would be less than significant with mitigation. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 19-12 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Land Use and Planning Similar to the proposed OPSP, Alternative B would not result in any significant land use impacts. It would not divide an established community, would not conflict with plans and policies intended to avoid or mitigate an environmental effect, and would not conflict with a conservation plan. Noise Because the square footage of office/R&D uses would be reduced by approximately 20% under Alternative B, it is expected that construction phases would be shortened, thereby decreasing the duration of construction-related noise in the OPSP area and resulting in somewhat reduced construction-related noise impacts compared to those described for the proposed OPSP. However, because the construction would still require an extended period of time, the impact would remain Significant and Unavoidable, even under Alternative B. Again, because of the reduced intensity of development including lower levels of resultant traffic, increases in noise at and in the vicinity of the site would be marginally less under Alternative B than under the proposed OPSP. These impacts are less than significant under either scenario. Transportation and Circulation Similar to the proposed OPSP, Alternative B would result in new vehicle trips in the vicinity, equating to roughly a 20% reduction in trips. The number of trips generated under this Alternative would still result in an increase over the threshold of 100 new vehicle trips, triggering the requirement of a TDM Plan. This degree of trip generation reduction would not reduce traffic levels sufficiently to reduce significant and unavoidable impacts, which are related to declines in operation of and unacceptable queuing at U.S. 101 ramps and/or intersections serving them or on the U.S. 101 mainline. These impacts would be marginally reduced under Alternative B compared to the proposed OPSP. Other impacts that can be brought to a less than significant level through mitigation would also be marginally reduced. Because the exact layout under Alternative B is not known, it is assumed that potential impacts related to pedestrian/vehicle conflict could be similar to those under the proposed OPSP and could be mitigated through improved design and facilities. Utilities and Service Systems Similar to the proposed OPSP, Alternative B would increase the demand for utilities, though to a lesser degree than under the proposed OPSP. However, a smaller project such as that proposed under Alternative B may not include as many energy or water-efficiency measures and may not be designed for LEED certification. Alternative B would still be required to comply with applicable regulations and contribute fair share costs toward sewer system improvements (upgrade of the Oyster Point subtrunk and Pump Station 2) anticipated to be required even under this alternative. Ability to Accomplish OPSP Objectives and Feasibility Alternative B would not support all project objectives. By reducing the proposed development intensity by approximately 20%, several project objectives are seriously compromised, including: CHAPTER 19: ALTERNATIVES OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 19-13 x The economic viability of transforming the area into a gateway into South San Francisco because the net property tax and other fees from development will be reduced; x Reorganizing the land use pattern and redeveloping underutilized land will be less feasible because less tax increment will be generated by projects that are within the redevelopment area and there would be less value in the private redevelopment to support public infrastructure and community benefits through a community facilities district; x There would be fewer users of the Ferry Terminal since South San Francisco’s terminal is an employment destination, and the fewer employees in the area, the fewer potential riders; and x There would be fewer jobs created during the construction and operation of the development. x This alternative would not create new recreational space or provide for landfill cover repair or protection from sea level rise. Without allowances of greater FAR for private development, many of the basic OPSP objectives could not be met. Alternative B would generate less revenue from private redevelopment and may not be economically feasible. The economic feasibility of completing the needed upgrades to the landfill site and upgrades to utilities and infrastructure and the environmental mitigation that would be required for these improvements and any re-development would be in question under this reduced intensity alternative. ALTERNATIVE C: REDUCED INTENSITY (FAR 1.12) ALTERNATIVE Impact Analysis The impact analysis below focuses on those impacts that were determined to be potentially significant under the proposed OPSP. Less than significant impacts are discussed only if implementation of the alternative will substantially increase the impact. Impact Summary Reducing the allowable office/R&D development to an FAR of 1.12 (a reduction of approximately 10%) would primarily reduce impacts related to vehicle trips and to some degree construction-period impacts, such as air quality emissions, traffic and noise. However, while Alternative C would marginally reduce some impacts, it would not, as discussed below, result in the avoidance or lessening of the identified significant and unavoidable impacts to a less than significant level. Aesthetics Similar to the proposed OPSP, Alternative C would replace single story office/light industrial buildings with larger, modern office/R&D buildings and would have no adverse impact on visual character. The already less-than-significant impact related to partial blockage of scenic views from public and private locations both on and off site would be anticipated to be somewhat reduced due to less building mass on the site. Lighting and building materials on the site under Alternative C would be anticipated to be similar to the proposed OPSP and would be subject to the same City standards as the proposed OPSP. Additionally, similar to the proposed OPSP, there would be no impact related to state scenic highways. Therefore, impacts to visual character and light and glare under Alternative C would be less than significant and the same as under the OPSP. Overall impacts to visual resources would be the same as under the OPSP. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 19-14 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Air Quality and Greenhouse Gas Emissions Because this Alternative would result in fewer vehicle trips to the OPSP site than the proposed OPSP as well as less building space requiring less water and using energy, air quality impacts and greenhouse gas emissions would be less than those identified under the proposed OPSP, roughly 10% lower. This would marginally reduce the already less-than-significant air quality impacts that had been identified under the OPSP. However, because greenhouse gas emissions are compared against an efficiency- based threshold and the reduction in square footage and traffic emissions under Alternative C would go along with a reduction in employees on the site, it is anticipated that the significant and unavoidable greenhouse gas emissions impact identified for the OPSP would be the same under Alternative C. As with the proposed OPSP, operation of Alternative C would not be anticipated to create objectionable odors affecting a substantial number of people. While the exact layout of buildings under the reduced-intensity Alternative C is not known, less building space would equate to marginally lower construction-period emissions, though BAAQMD fugitive dust and emissions reduction measures would be required to reduce the impact to less than significant and BAAQMD-recommended construction greenhouse gas reduction measures would be implemented to further reduce impacts, as under the proposed OPSP. As with the proposed OPSP, any proposed auxiliary uses which would bring sensitive users to the site for long periods each day (such as a daycare facility) would require assessment of the health risk. This impact would be the same under Alternative C as under the proposed OPSP. Because Alternative C would result in greater development intensity than that assumed under the General Plan, a Significant and Unavoidable impact related to increases in vehicles miles traveled above that assumed in the Clean Air Plan would remain though it would be slightly reduced from that under the OPSP. Biological Resources While habitats in the OPSP area are generally not particularly sensitive, valuable (from the perspective of providing important wildlife habitat), or exemplary occurrences and would represent no substantial loss of foraging or non-breeding habitat for any special-status species, there is the possibility of impacting wetland or aquatic habitats and/or special-status species within them primarily through in- water construction related to replacement of a couple docks and work on the shoreline Bay Trail, both of which are proposed under either the OPSP or Alternative C, so the impact would be the same. These areas could additionally be impacted by sediment from construction-period runoff, though this would be similar under either the proposed OPSP or Alternative C and mitigated through minimizing near- water soil disturbance and incorporating best management practices. Again, because the exact layout under Alternative C is not known, it is assumed that potential impacts related to stormwater outfall and the wetlands/tidal channel on the southwestern part of the site would be similar to those under the proposed OPSP and could be mitigated through assurance of adequate capacity and maintenance of the stormwater system. While burrowing owls were not found on the site, they could take up residence prior to construction, under either the proposed OPSP or Alternative C. Additionally, most nesting birds are protected under the Migratory Bird Treaty Act of 1918 and/or Fish and Game Code of California. Nesting birds or burrowing owls could be disturbed by construction activities. The impacts would be similar under either the proposed OPSP or Alternative C and would require pre-construction surveys with appropriate mitigation if nesting birds or burrowing owls are found to ensure these impacts are less than significant.

ENVIRONMENTALLY SUPERIOR ALTERNATIVE In addition to the discussion and comparison of impacts of the proposed OPSP and the alternatives, Section 15126.6 of the CEQA Guidelines requires that an “environmentally superior” alternative be selected and the reasons for such a selection disclosed. In general, the environmentally superior alternative is the alternative that would be expected to generate the least amount of significant impacts. Identification of the environmentally superior alternative is an informational procedure and the alternative selected may not be the alternative that best meets the goals or needs of the City. DRAFT ENVIRONMENTAL IMPACT REPORT PAGE 19-18 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Table 19.1, on the following pages, provides a summary comparison of the environmental impacts of the alternatives compared to the proposed OPSP. The table lists the level of significance of the impacts of the proposed OPSP to each of the environmental topics areas analyzed in the EIR and shows whether the impacts anticipated under each proposed alternative would be similar to (“s”), greater (“+”) or lesser (“-”) than the proposed OPSP. Alternative A, the No Project/No Redevelopment Alternative, proposes development only on a currently vacant parcel and would result in the fewest employees on the site and therefore, the least amount of vehicle trips, roughly only 5% of the trips that would have been seen under the proposed OPSP. This lesser amount of trips would provide the largest decrease in operational emissions, vehicular-related noise increases, and traffic impacts, including avoidance of all the identified Significant and Unavoidable impacts under the proposed OPSP. However, benefits identified under the OPSP would not be realized under Alternative A, such as improvements to the landfill cover, remediation of the industrial sumps, protection against sea level rise and provision of recreational areas. Nonetheless, on balance, Alternative A would be the environmentally superior alternative. The CEQA Guidelines also require that “if the environmentally superior alternative is the ‘no project’ alternative, the EIR shall also identify an environmentally superior alternative among the other alternatives” (CEQA Guidelines Section 15126.6(e)(2)). In general, the environmentally superior alternative minimizes adverse impacts to the environment, while still achieving the basic project objectives. The other two alternatives, Alternatives B and C, would reduce the amount of development on the site, resulting in roughly 80% or 90% of the trips as would have been generated under the proposed OPSP, respectively. However, although these alternatives would result in some reduction of employees or vehicle trips to the OPSP site, they would not reduce impacts to a degree that would reduce the Significant and Unavoidable impacts to air quality, GHG, noise, and traffic to a less than significant level. Therefore, no analyzed alternative is superior in this regard and, similar to the proposed OPSP, all analyzed alternatives would result in the significant and unavoidable impacts. Additionally, Alternatives B and C may not be economically feasible. They would generate less revenue from private redevelopment. With this reduced revenue, the completion of needed upgrades to the landfill site and upgrades to utilities and infrastructure and the environmental mitigation that would be required for these improvements and any re-development would be in question under Alternatives B and C.

OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 21-1 21 INTRODUCTION TO THE FINAL EIR PURPOSE OF THE FINAL EIR The California Environmental Quality Act and the Guidelines promulgated thereunder (together “CEQA”) require an Environmental Impact Report (EIR) to be prepared for any project which may have a significant impact on the environment. An EIR is an informational document, the purposes of which, according to CEQA are “to provide public agencies and the public in general with detailed information about the effect which a proposed project is likely to have on the environment; to list ways in which the significant effects of such a project might be minimized; and to indicate alternatives to such a project.” The information contained in this EIR is intended to be objective and impartial, and to enable the reader to arrive at an independent judgment regarding the significance of the impacts resulting from the proposed project. This document, together with the Draft Environmental Impact Report (Draft EIR) published in January 2011, shall constitute the Final Environmental Impact Report (Final EIR) prepared pursuant to the California Environmental Quality Act (CEQA) as amended (commencing with Section 21000 of the California Public Resources Code) and the CEQA Guidelines for the proposed Oyster Point Specific Plan (OPSP), including the first phase of development (Phase I Project) in the City of South San Francisco, California and the related Redevelopment Plan amendment. The applicant is Oyster Point Ventures, LLC and the City of South San Francisco Redevelopment Agency. The Lead Agency is the City of South San Francisco. The applicant is seeking amendments of the City’s General Plan, Redevelopment Plan and Oyster Point Marina Specific Plan, as well as several entitlements to enable development of the OPSP, including but not limited to approval of a subdivision or parcel map, design review, a Transportation Demand Management (TDM) Plan, a Development Agreement, and a Disposition and Development Agreement to enable redevelopment of the OPSP and Phase I Project site. The OPSP would include replacing the existing light industrial/office park with an office/research and development (R&D) development, improvements to the site circulation, utilities, and landfill cap, provision of a flexible use recreation area and bay-front open space, and replacement of uses in the Oyster Point Marina area, potentially including one or two hotels with an aggregate of up to 350 rooms. Approval must be given by the City of South San Francisco and trustee agencies, including the Regional Water Quality Control Board and Bay Conservation and Development Commission before construction may begin. EIR REVIEW PROCESS Draft EIR A Draft EIR was made available for public review in January 2011. During the public review period for the Draft EIR (ending March 10, 2011), the City received verbal comments from the South San Francisco Planning Commission and written comments. FINAL ENVIRONMENTAL IMPACT REPORT PAGE 21-2 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Final EIR This Final EIR contains all comments received by the City on the Draft EIR and also includes responses to these comments, together with necessary changes or revisions to the text of the Draft EIR document. Changes to the text of the Draft EIR are included in Chapter 22 of this Final EIR, shown in underline for new text or strikeout for deleted text. None of the revisions or responses to comments contained in this Final EIR would be considered “significant new information” under section 15088.5 of the CEQA Guidelines and therefore no recirculation of the Draft EIR would be required. This Final EIR will be presented to the Planning Commission and City Council at public hearings to consider recommendation for and certification of this document as a technically adequate, full disclosure document consistent with the requirements of CEQA. Assuming certification of this EIR as complete and adequate under CEQA, this document together with the Draft EIR will constitute the EIR for this Project. The Planning Commission may recommend and the City Council may require additional changes or modifications to this Final EIR prior to certification. An EIR does not control the agency’s ultimate discretion on the OPSP. As required under CEQA, the agency must respond to each significant effect identified in the EIR by making findings and if necessary and warranted, by adopting a statement of overriding considerations. In accordance with California law, the EIR must be certified before any action on the project can be taken. However, EIR certification does not constitute project approval. REPORT ORGANIZATION This Final EIR consists of the following chapters, commencing after Chapter 20 of the Draft EIR: Chapter21: Introduction to the Final EIR. This chapteroutlines the purpose, organization and scope of the Final EIR document and important information regarding the public review and approval process. Chapter 22: Revisions to the Draft EIR. This chapter includes corrections, clarifications or additions to text contained in the Draft EIR based on comments received during the public review period. Chapter 23: Response to Comments. This chapter provides reproductions of letters received on the Draft EIR. The comments are numbered in the right margin. The responses to comments are also provided in this chapter immediately following each comment letter, and are keyed to the numbered comments. Chapter 24: Mitigation Monitoring and Reporting Program. This chapter contains the Mitigation Monitoring and Reporting Program (MMRP) to be adopted to ensure that the mitigation measures identified in the EIR are implemented. OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 22-1 22 REVISIONS TO THE DRAFT EIR REVISIONS TO THE DRAFT EIR The following are minor text changes, additions or modifications made to the Draft EIR for the Oyster Point Specific Plan and Phase I Project. An explanation of the changes made in response to comments can be found in Chapter 23. Comments, including the original location in the Draft EIR of the text to be changed, are in italics. Deletions are noted by strikethrough. Additions are underlined. CHANGES TO CHAPTER 2: EXECUTIVE SUMMARY x Page 2-1, paragraph 4 The following revision is made to clarify the timing of completion of the ferry terminal. The South San Francisco Ferry Terminal with service to/from San Francisco and the East Bay is currently under construction and scheduled is anticipated to be completed at the Oyster Point Marina in early by the end of 2011. x Page 2-1, paragraph 4 The following revision is made to clarify the number of berths in the Oyster Point Marina. The Oyster Point Marina is located on the north side of the Oyster Point Marina area and contains 600 465 berths, a boat ramp, fuel dock and fishing pier. x Page 2-12 Mitigation measure Traf-26 is hereby revised in Table 2.1, consistent with revisions to page 16-51. x Page 2-36 Impact Geo-14 and mitigation measure Geo-14 were accidently omitted from the summary table. They are hereby added to Table 2.1, as follows. FINAL ENVIRONMENTAL IMPACT REPORT PAGE 22-2 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Potential Environmental Impacts Recommended Mitigation Measures Resulting Level of Significance Impact Geo-14: Soil Erosion. The OPSP would involve mass grading at a location that drains stormwater to the San Francisco Bay. Demolition of existing structures and pavements could expose underlying landfill cap soils to the elements. Excavation of soil for construction of new buildings and pavement sections would also be performed and temporary stockpiles of loose soil will be created. Soils exposed during site grading would be subject to erosion during storm events. Grading would disturb site soils potentially leading to impacts to the San Francisco Bay. This would be a potentially significant impact during and following site construction activities. Geo-14: Storm Water Pollution Prevention Plan. In accordance with the Clean Water Act and the State Water Resources Control Board (SWRCB), the Applicant shall file a Storm Water Pollution Prevention Plan (SWPPP) prior to the start of construction. The SWPPP shall include specific best management practices to reduce soil erosion. This is required to obtain coverage under the General Permit for Discharges of Storm Water Associated with Construction Activity (Construction General Permit, 99-08-DWQ). Less than Significant Impact Geo-16 and mitigation measure Geo-16 are hereby added to Table 2.1, consistent with revisions to page 9-19. CHANGES TO CHAPTER 3: PROJECT DESCRIPTION x Page 3-2, paragraph 3 The following revision is made to clarify the timing of completion of the ferry terminal. The South San Francisco Ferry Terminal with service to/from San Francisco and the East Bay is currently under construction and scheduled is anticipated to be completed at the Oyster Point Marina in early by the end of 2011. x Page 3-2, paragraph 2 The following revision is made to clarify the number of berths in the Oyster Point Marina. The Oyster Point Marina is located on the north side of the Oyster Point Marina area and contains 600 465 berths, a boat ramp, fuel dock and fishing pier. x Page 3-2, 1st bullet point The following revision is made to clarify that demolition of the Yacht Club is not proposed. x demolition of the existing inn located at 425 Marina Drive, the office buildings at 360 Oyster Point Boulevard and 401 Marina Boulevard, the boat and motor mart at 671 Marina Boulevard, the Yacht Club at 911 Marina Boulevard, and the light-industrial buildings at 375-389 Oyster Point Boulevard, CHAPTER22: REVISIONS TO THE DRAFT EIR OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 22-3 x Page 3-3, Table 3.1 The following revisions are made to clarify the number of berths in the Oyster Point Marina and that demolition of the Yacht Club is not proposed.

SUSTAINABILITY OF BAYSIDE OPEN SPACE Impact Geo-16: Bayside Open Space Wave Stability. The bayside open space area could be subject to wave action, which could erode improvements and potentially lead to instability. The potential for erosion and instability of the bayside open space area is considered a potentially significant impact. Mitigation Measures Geo-16: Compliance with Recommendations of a Coastal Engineer. A design- level investigation of the sustainability of the proposed bayside open space in the local wave environment shall be prepared by a qualified coastal engineer. Elements of this analysis shall include an investigation of the FINAL ENVIRONMENTAL IMPACT REPORT PAGE 22-4 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT local wave environment at the proposed bayside open space location, development and verification of numerical models of local wave action based on comparisons of measured and predicted wave heights, and application of the predictive numerical models to refine the open space design. Depending on the results of this investigation, the design of the bayside open space may need to incorporate protection measures such as structural elements (e.g., concrete seatwalls) and/or buffer zones (i.e., lengths of flat beach between the dynamic beach slope and any needed structural elements). The design plans shall incorporate appropriate recommendations from this investigation. If the recommendations require any construction in-water or near the shoreline, these may require subsequent permitting from BCDC and/or USACE and would also be subject to mitigation measures Bio-12, -13a, - 13b, 14a, -14b, -14c, -15a, -15b, and -15c. Conformity with mitigation measure Geo-16 would reduce the impact of erosion and wave action on the bayside open space to a level of less-than-significant. CHANGES TO CHAPTER 15: POPULATION, PUBLIC SERVICES, RECREATION x Page 15-7 The following text is hereby added to specify that the Bay Trail runs through the area and has its own plan. The San Francisco Bay Trail runs through the OPSP area and is programmed through the regionally adopted San Francisco Bay Trail Plan (ABAG, 1989) CHANGES TO CHAPTER 16: TRANSPORTATION AND CIRCULATION x Page 16-15 The following text is hereby added to reference the Bay Trail specifically. The San Francisco Bay Trail is an existing multi-use bicycle and pedestrian facility along the shoreline in the OPSP area and is programmed through the regionally adopted San Francisco Bay Trail Plan (ABAG, 1989) x Page 16-20 The following change is made to Table 16.11 to correct the LOS reference as shown.

Impact Traf-2b: Construction Disruption of Bay Trail. Continuity of the Bay Trail could be disrupted by construction activities in the OPSP area. This is considered a potentially significant impact. Mitigation Measures Traf-2b: Bay Trail Continuity Provisions in Construction Management Plan. Continuity of the Bay Trail shall be included in construction management plans for all phases of development in the OPSP. When feasible, construction shall avoid disrupting the Bay Trail and when not feasible, the construction management plan shall specify plans for clear and safe detours for bicyclists and pedestrians and be ADA accessible. Conformity with mitigation measure Traf-2b will reduce the impact of disruption of the Bay Trail during construction activities to a level of less-than-significant. x Pages 16-46 and 16-47 The following revision is made to correct inconsistencies in the discussion of resultant operation following implementation of mitigation measure Traf-19. Mitigation Measure Traf-19: Intersection Level of Service.

OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 23-1 23 RESPONSE TO COMMENTS INTRODUCTION This chapter contains response to the Commissioner comments from the February 17, 2011 Planning Commission hearing and written comments on the Draft EIR. Where revisions to the Draft EIR are appropriate, such changes are summarized below and the actual text changes are included in Chapter 22. The City of South San Francisco received five (5) letters commenting on the Oyster Point Specific Plan and Phase I Project Draft EIR during the comment period. The comments are organized in chronological order as follows: Meeting PC: Planning Commission Meeting February 17, 2011 Letter A: John Bergener, San Francisco International Airport Letter B: Rob Wood, Native American Heritage Commission Letter C: Ming Yeung, San Francisco Bay Conservation and Development Commission (BCDC) Letter D: Peter Grenell, San Mateo County Harbor District Letter E: Laura Thompson, San Francisco Bay Trail Project RESPONSES TO SPECIFIC COMMENTS The following pages contain comments on the Draft EIR. Each comment is numbered and responses to these comments are provided following each comment letter. In some instances, responding to a comment received on the Draft EIR resulted in a revision to the text of the Draft EIR. In other cases, the information provided in the responses is deemed adequate in itself, and modification of the Draft EIR text was not necessary. FINAL ENVIRONMENTAL IMPACT REPORT PAGE 25-2 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT MEETING PC: PLANNING COMMISSION MEETING FEBRUARY 17, 2011 A public hearing to collect comment on the Draft EIR was held before the South San Francisco Planning Commission on February 17, 2011. There were no comments received during the public portion of the hearing. The Commissioners made a few comments, some of which related to the specifics of the project description or broader plans for the East of 101 area. The official minutes of this meeting are not yet available, so the Planning Commission’s comments relating to the environmental analysis have been summarized below with responses following. Comment PC-1 The Commission asked how the fact that the area is low would affect the ability to provide sewer service and whether settling was an issue for sewer pipes. Response to Comment PC-1 The project proposes relocation of the existing on-site pump station #1 at 383 Oyster Point Boulevard and installation of an additional pump station in the Oyster Point Marina area, as discussed on pages 17-9 and 17-10. Additionally, Mitigation Measures Util-2a and Util-2b require upgrading of the off- site pump station #2 and sewer lines to assure adequate capacity for cumulative growth in the East of 101 Area including the OPSP. On the area that is a former landfill, the Phase I Project will involve relocating of landfill materials and reconstruction of the landfill cap. As part of that process, new utility pipes will be installed. Mitigation Measures Geo-11, Geo-12 and Geo-13 (page 9-17) address settling and other concerns regarding sustainability of utility infrastructure by encouraging location of utilities in common tranches, requiring the use of flexible pipe, and increasing gradient flow to offset differential settlements. These measures are designed to ensure that new utility lines and connections continue to function properly as further settlement occurs over time. Comment PC-2 The Commission noted that the construction period for total build-out of the OPSP would continue over a long period with some intermittent gaps in between and wanted to be sure noise and air quality/health impacts had been analyzed and minimized for the entire construction period for both the nearby tenants as well as families that may use the Bay Trail and proposed recreation facilities. He asked whether the pacing of construction activity could be evaluated to minimize these impacts. Response to Comment PC-2 The proposed construction schedule for the Phase I Project was input into air quality modeling and considered for determination of the noise impacts, as discussed in the Draft EIR on pages 6-16 through 6-21 and 14-16 through 14-19, respectively. As construction of the office/R&D project is proposed to occur in four approximately equally sized phases, it is reasonable to anticipate that impacts would be similar for each phase. Mitigation measures have been recommended that would reduce potential construction-period impacts for each construction phase including Air-4a and -4b to reduce dust, diesel particulate matter and odors (pages 6-19 and 6-20) and Noise-5 to reduce noise levels generated by construction activities (page 14-18). These would apply to Phase I construction as well as subsequent phases. These mitigation measures would ensure impacts related to construction period emissions and noise are reduced to the extent feasible. However, while potential noise impacts have been reduced to the CHAPTER 23: RESPONSE TO COMMENTS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 23-3 extent feasible, the noise from construction activities can still be intermittently disruptive. Because of the duration of the construction period for a project that would be implemented over many years, the noise impact has been determined to be significant and unavoidable. As for the pacing of construction, it is anticipated this will be informed by economic impetus as well as the realities of coordinating such large construction projects and could only be constrained to a minimal degree. It is more a qualitative question of whether slightly less noise over a longer period would be more palatable than slightly more noise over a shorter period when we are discussing a matter of many years. Successive phasing as proposed from the south to the northern part of the site will help move noise and emissions sources away from the new uses coming on-line as each phase is completed and limit impacts over time to the extent possible. There is no recommendation for modification of the construction phasing from that proposed. Comment PC-3 The Commission followed-up on the previous question relating to the low level of the area by asking whether the area would need to be re-diked and if so how that would impact the Bay Trail and liquefaction. Response to Comment PC-3 Development in the OPSP area will generally avoid development or other activities within tidal areas, marshland or in-water, with the exception of possible changes to docks in the Oyster Point Marina, which are not proposed as a part of the Phase I Project and for which there are no specific design or construction proposals. If, during the approval process for specific development projects, it is determined that activities will encroach into these areas, appropriate review and permits will be pursued. The grading plan can be found in the Draft EIR, Figure 3.5. The changes to the grading in relation to anticipated future sea level rise can be seen graphically on Figures 12.1 and 12.2 on pages 12-13 and 12-14, which demonstrate how the proposed grading will protect proposed uses including enhancements to the Bay Trail, from future sea level rise. The potential for liquefaction at the site is discussed on page 9-8, as excerpted below: “Based on the subsurface data obtained from the previous drilled borings at Oyster Point (noted above among the references reviewed), the existing landfill materials, residual soils, Bay Mud, and Franciscan Complex bedrock have a low potential for liquefaction. Therefore, damage due to liquefaction at Oyster Point is considered low. It should be noted that the landfill is contained by soil dikes along the water-side site perimeter. These perimeter dikes are reported to have been constructed of Bay Mud, which has low potential for liquefaction. Prior to new site development, geotechnical studies shall be undertaken to confirm the material types used in the construction of the perimeter dikes to verify the assumed low potential for liquefaction.” Mitigation Measure Geo-4 outlines the specifics of compliance with recommendations of a geotechnical investigation including static and seismic stability of the perimeter dikes (pages 9-11 and 9-12). LetterA A- 1 A- 1 c o n t ' d . A- 2 A- 3 FINAL ENVIRONMENTAL IMPACT REPORT PAGE 23-6 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT LETTER A: JOHN BERGENER, SAN FRANCISCO INTERNATIONAL AIRPORT Response to Comment A-1 The current San Mateo County Comprehensive Airport Land Use Plan was prepared an adopted by the City/County Association of governments of San Mateo County (C/CAG) in its designated role as the Airport Land Use Commission for San Mateo County, California in December 1996. The OPSP was determined in this EIR to be consistent with regulations of the Comprehensive Airport Land Use Plan related to environmental issues (see hazards/height discussion on pages 11-18 and 11-19 and noise discussion on page 14-19) and as noted in this comment, the project will undergo consistency review through the San Mateo County Airport Land Use Commission. On February 24, 2011, the C/CAG Airport Land Use Committee unanimously recommended that the C/CAG Board, acting as the Airport Land Use Commission, find that the Oyster Point Specific Plan and Phase I Project is consistent with the December 1996 Comprehensive Airport Land Use Plan. The C/CAG Board is scheduled to consider the matter on March 10, 2011. It is understood that the project referenced in the third paragraph was intended to be the Oyster Point Specific Plan and Phase I Project and not the Transit Corridors Plan. Note that it is anticipated the EIR for this project will be certified in March 2011, prior to adoption of a new Comprehensive Airport Land Use Plan. Response to Comment A-2 As noted on pages 11-18 and 11-19 of the Draft EIR, the building heights proposed are below the permissible limits. Response to Comment A-3 As discussed on page 14-14 of the Draft EIR, the hotel will comply with the California State Building Code and the City of South San Francisco General Plan, which require interior noise levels to be maintained at or below 45 dBA CNEL. Noise modeling and comparison to the noise contour map in the South San Francisco General Plan indicate that predicted interior noise levels at the proposed hotel site would be below this level assuming standard hotel construction. See also Impact Noise-6 and the following discussion on 14-19 for additional information. No new residential uses are proposed or permitted as part of the OPSP. LetterB B- 1 CHAPTER 23: RESPONSE TO COMMENTS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 23-9 LETTER B: ROB WOOD, NATIVE AMERICAN HERITAGE COMMISSION Response to Comment B-1 These comments outline standard practice for cultural review of a project. The recommended actions are incorporated in the Draft EIR, pages 8-1 to 8-6. The Oyster Point EIR references the Ferry Terminal study conducted in the Project area in 2005. This previous Sacred Lands File check "failed to indicate the presence of Native American resources" in the area (While also referenced in the Draft EIR, the full reference to the Ferry Terminal EIR is: San Francisco Bay Area Water Transit Authority, prepared by EIP, Draft Environmental Impact Report/Environmental Assessment, South San Francisco Ferry Terminal Project, February 2006). Additionally, because the original shoreline in the area would have been 2000 feet west and 3000 feet south of the OPSP site (see pages 8-4 and 8-6 for additional information), there is a very low likelihood that undiscovered historical/Native American resources or remains will be encountered during construction activity. Nonetheless, the Draft EIR includes Mitigation Measures Culture-1a and Culture-1b, which require construction activity to be halted and appropriate action taken in the event any cultural resources or remains are discovered (page 8-6 of the Draft EIR). The following message has been sent to the tribal consultation list attached to the comment letter, though as discussed above, no responses are anticipated: Lamphier-Gregory has been contracted to prepare the environmental analysis for the Oyster Point Specific Plan (OPSP) in South San Francisco. The project area is situated at Oyster Point in unsectioned land, in Township 3 South, Range 5 West as depicted on the San Francisco South and Hunters Point USGS 7.5’ topographic quadrangles (attached). The OPSP would include replacing the existing light industrial/office park with an up to 2,300,000 square foot office/research and development (R&D) development, improvements to the site circulation, utilities, and the landfill cap, provision of a flexible use recreation area and bay-front open space, and replacement of uses in the City’s Oyster Point Marina area, potentially including one or two hotels with an aggregate of up to 350 rooms. A previous Sacred Lands File check did not to indicate the presence of Native American Resources and historic assessment indicates the site is on fill at least 2000 feet into the Bay from the original shoreline and therefore the site is unlikely to include Native American remains or cultural resources. We are contacting individuals identified by the Native American Heritage Commission as persons who might have information to contribute regarding potential Native American concerns in the project area. Any information or concerns that you may have regarding village sites, traditional properties or modern Native American uses in any portion of the project vicinity will be welcomed. If you know other individuals who are familiar with the vicinity, we would welcome this information as well.

If, during the approval process for specific development projects, it is determined that activities will encroach into this area or into the 100 foot shoreline band, appropriate permits will be pursued from BCDC along with any required plans. Because possible changes to two of the docks in the Oyster Point Marina were being contemplated during preparation of the Draft EIR, the potential environmental impacts associated with potential in- water construction for these docks were analyzed in the Draft EIR at a programmatic level of detail, consistent with the level of detail currently known about these contemplated changes. These potential actions are not part of the Phase I Project and there is currently no specific design or construction proposal for such docks. If changes to the docks are indeed proposed at a later date, the specifics will need to undergo appropriate review and permitting. Response to Comment C-2 The Waterfront Park Priority designation was discussed on pages 13-2 to 13-3 of the Draft EIR. The City will continue to coordinate with BCDC during the approval/permitting process to ensure consistency with exact boundaries of waterfront priority designations. Response to Comment C-3 No Bay fill is currently proposed as a part of the OPSP or Phase I Project. If, during the approval process for specific development projects, it is determined that any subsequent activity will require Bay fill, such as for changes to the docks (the specifics of which are not currently available), appropriate review and permitting will be pursued at that time. Response to Comment C-4 This is not a comment on the environmental analysis. Appropriate detail will be provided for any permitting through BCDC. Response to Comment C-5 This is not a comment on the environmental analysis. When final development plans for the future hotel development site and flexible use recreation area are planned/programmed, details of the public access through these sites will be considered, including connections to/from Marina Boulevard and the Bay Trail and/or through the Phase I Office/R&D site to Gull Drive. Response to Comment C-6 Full and detailed analysis of aesthetic impacts was included in the Draft EIR on pages 4-1 through 4- 20, including visual models from four locations. This analysis meets the requirements for CEQA review. Additional detail and discussion can be provided as required for any subsequent permitting through BCDC. With the planned roadway realignment, bayside open space, recreational area and Bay Trail improvements, the project will provide, enhance and preserve views of the Bay and shoreline. CHAPTER 23: RESPONSE TO COMMENTS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 23-17 Response to Comment C-7 The Draft EIR included a full and detailed analysis of potential biological impacts on pages 7-1 to 7- 38 and Appendix C of the Draft EIR. This information included recommended mitigation measures and aspects of the proposed project’s construction and use that would avoid or minimize impacts to special-status species and habitat. This analysis also included a full assessment of in-water impacts that could result if changes to the docks are subsequently proposed including measures to minimize potential impacts (see pages 7-31 to 7-37). Response to Comment C-8 The Draft EIR included a full and detailed analysis of potential impacts to water quality and recommended measures to reduce these impacts on pages 12-6 through 12-11, including measure Hydro-1 requiring best management practices during installation of foundation piers, Hydro-2 requiring preparation and implementation of a Storm Water Pollution Prevention Plan, Hydro-3 requiring compliance with NPDES requirements for erosion control measures, and measures requiring monitoring for leachate from the landfill (Haz-4a, Haz-4d and Haz-4e). Response to Comment C-9 No Bay fill is currently proposed as a part of the OPSP or Phase I Project. If, during the approval process for specific development projects, it is determined that any subsequent activity pursuant to the OPSP will require Bay fill, such as for changes to the docks (the specifics of which are not currently available), appropriate review and permitting will be pursued at that time. Response to Comment C-10 Impact and Mitigation Measure Geo-16 have been added to address the stability of the bayside open space and require investigation by and compliance with recommendations of a coastal engineer. See the revisions in Chapter 22 of this document. Compliance with mitigation measure Geo-16 will reduce potential impacts related to instability of the bayside open space to a level of less than significant. Response to Comment C-11 Development in the OPSP area will generally avoid development or other activities within tidal areas, marshland or in-water, with the exception of possible changes to docks in the Oyster Point Marina, discussed below. If, during the approval process for specific development projects, it is determined that activities will encroach into these areas, appropriate review and permits will be pursued. Because possible changes to two of the docks in the Oyster Point Marina were being contemplated during preparation of the Draft EIR, the potential environmental impacts associated with potential in- water construction for these docks were analyzed in the Draft EIR at a programmatic level of detail, consistent with the level of detail currently known about these contemplated changes. These potential actions are not part of the Phase I Project and there is currently no specific design or construction proposal for such docks. If changes to the docks are indeed proposed at a later date, the specifics will need to undergo appropriate review and permitting. Response to Comment C-12 The potential impact of future sea level rise is discussed in full on pages 12-11 through 12-15 of the Draft EIR. Figure 12.2 of the Draft EIR demonstrates protection of the entire development area under proposed grading conditions, including the public access areas, under potential sea level rise scenarios.

CHAPTER 23: RESPONSE TO COMMENTS OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT PAGE 23-23 Response to Comment D-18 Impact Hydro-4 is discussed in full on pages 12-11 through 12-15 of the Draft EIR, including Figure 12.2 that demonstrates protection of the entire development area under proposed grading conditions, including the eastern end of the shoreline. Response to Comment D-19 The environmental analysis was completed to satisfy requirements under the California Environmental Quality Act for the Oyster Point Specific Plan and Phase I Project, including infrastructure improvements, which includes full and detailed analysis of traffic on pages 16-1 through 16-58 and Appendix E of the Draft EIR including identification of significant and unavoidable impacts to US 101 and the ramps and/or intersections serving them and identification of 18 additional potentially significant impacts and the mitigation to reduce these to less than significant; full and detailed analysis of hazardous materials on pages 11-1 through 11-19 of the Draft EIR including impacts and mitigation for potentially significant impacts related to hazardous and potentially hazardous landfill materials; and full and detailed analysis of geological impacts on 9-1 through 9-19 of the Draft EIR including impacts and mitigation relating to construction over variable subsurface conditions including landfill materials that may subside over time and in a seismically active region. Additionally, the adequacy of the proposed utility infrastructure was examined in a full and detailed analysis included in the Draft EIR on pages 17-1 through 17-16 and Appendix G. The comment does not raise any specific environmental issue to which a specific written response can be provided; accordingly no further response is required Response to Comment D-20 Page 1-1, 2nd paragraph identifies the applicant as “Oyster Point Ventures, LLC and the City of South San Francisco Redevelopment Agency.” Chapter 3: Project Description describes in more detail the proposed public-private redevelopment. Response to Comment D-21 As outlined in the first paragraph of page 3-1 of the Draft EIR, the Phase I Project has been analyzed on a project level in the EIR. Because elements of the future phases within the OPSP are conceptual at this point, these have been analyzed on a programmatic level. While conceptual, as much detailed information as possible has been included for future phases to ensure a more exhaustive consideration of effects and alternative for the entire OPSP than would have been possible if each phase had been considered separately. See the detailed description of the programmatic OPSP on pages 3-2 through 3-4 and 3-19 of the Draft EIR. Programmatic analysis is explicitly allowed for projects of this type under section 15168 of the CEQA Guidelines, and is a common practice for large multi-phase Specific Plans that would not be considered “segmentation” under CEQA. Response to Comment D-22 The comment has been evaluated, but does not raise an environmental issue, nor address the adequacy of the environmental analysis. Pursuant to Public Resources Code Section 21091(d)(2), and CEQA Guidelines Section 15088, no further response is required. FINAL ENVIRONMENTAL IMPACT REPORT PAGE 23-24 OYSTER POINT SPECIFIC PLAN AND PHASE I PROJECT Response to Comment D-23 This is not a comment on the environmental analysis. This non-CEQA issue will be coordinated between the City and Harbor District. If temporary enhancements are subsequently proposed in connection with the Americas Cup competition, these may require subsequent environmental review.

SPECIAL-STATUS PLANT SPECIES REJECTED FOR OCCURRENCE...79 Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 2010iii INTRODUCTION This report describes the biological resources within the boundaries of the Oyster Point Business Park and Marina Area Redevelopment Master Plan (hereafter referred to as the “Project”). Phase I of the Project includes the development of up to 600,000 square feet (ft) of offices and Research and Development (R&D) facilities on approximately 10 acres (ac) in the southwestern corner of the Project area; the creation of approximately 3.4 ac of waterfront open space in the central portion of the Project area behind the intersection of Oyster Point Boulevard and Marina Boulevard; construction of a 3.8-ac recreational field complex immediately east of the proposed office facility; grading of a 9-ac planned hotel site adjacent to the proposed recreational field complex; and the construction of new multi-use roads serving the Oyster Point Marina. Subsequent phases of the Project will entail a variety of activities including construction of an additional 1,800,000 square ft of office and R&D space; landfill cap repairs; rehabilitation and enhancement of roads, parking lots, landscaping, public facilities, and utilities infrastructure; improvements to the Bay Trail and associated open spaces throughout the Project area; and connectivity with the previously permitted Oyster Point Ferry Terminal. These phases of the Project, while treated programmatically in this document, will undergo separate project-specific environmental analyses as planning moves forward. This report includes a project-specific analysis of Phase I of the Master Plan, and a programmatic analysis of the remainder of the Master Plan. Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 20101 PROJECT DESCRIPTION PROJECT LOCATION The Project site is part of the City of South San Francisco’s “East of 101” Planning Area, the traditional and continued core of South San Francisco’s industrial and technological businesses, including bioscience offices. The East of 101 area consists of roughly 1700 ac of land bound by San Francisco Bay on the east side, Highway 101 and railway lines on the west, the City of Brisbane on the north, and San Francisco International Airport on the south. The area has a mix of land uses, including industry, warehousing, retail, offices, hotels, marinas, and bioscience research and development facilities. The area is also separated from most of South San Francisco’s residential uses by U.S. 101, though some houseboats are permitted at Oyster Point. The approximately 80-ac Project site is located approximately 3/4 mile east of Highway 101, at the eastern end (Bay side) of Oyster Point and Marina Boulevards. Figure 1 shows the general Project location and Figure 2 shows the proposed Project boundaries and phases. EXISTING USES The Oyster Point Business Park encompasses 25 ac of the Project area. It is a privately owned series of five single-story light-industrial buildings at 375-389 Oyster Point Boulevard that were developed in the early 1980s, totaling 404,000 square ft of space with surrounding parking. Currently these buildings are occupied by a variety of light industrial, office, and R&D tenants. Other than roadway elements, the 48-ac Oyster Point Marina fills the remainder of the Project area. This land served as a municipal landfill for the City of South San Francisco from 1956 until it stopped accepting waste in 1970. The Marina is owned by the City of South San Francisco and managed through a Joint Powers Agreement with the San Mateo County Harbor District. Currently, this area includes a variety of uses including a dry boat storage area, a marine support services building, two small office buildings, and a 30-room inn and banquet hall. The remaining area is vacant or serves as parking for the docks, boat ramp, and the Bay Trail at the Oyster Point Marina. The Oyster Cove Marina is located to the west of the Oyster Point Business Park and contains 235 berths. The larger Oyster Point Marina is located on the north side of the Oyster Point Marina area and contains 600 berths, a boat ramp, fuel dock and fishing pier. A previously permitted ferry terminal with service to the East Bay is currently scheduled to be completed at the Oyster Point Marina in early 2011, and is not part of the current Project.

Private development will include new office/R&D buildings in the western portion of the site, which will entail the following elements: x Demolition of the existing restaurant and hotel located at 425 Marina Drive, and the light- industrial buildings at 375-389 Oyster Point Boulevard x New public roadway alignment (and utility infrastructure) of Oyster Point Boulevard and Marina Drive x Office/R&D buildings within the 41 ac of private land area, built in four phases of approximately 500,000 to 600,000 square ft each x Each phase will include or have access to courtyards, plazas, shuttle bus stops, and/or structured parking x Dedication and construction of an approximately 4-ac parcel for use as a beachfront open space. Public redevelopment will include public open space, recreation fields, marina improvements, and a site that could accommodate a future hotel at the eastern end of the site, entailing the following elements: x Preparation of a site to accommodate a future hotel which will include up to 350 rooms and 40,000 square ft of retail/restaurant x New road and utility infrastructure to serve the future hotel site and Oyster Point Marina x A recreation field complex x A shuttle bus turnaround and reconfiguration of parking adjacent to the new ferry terminal x Improvements to the Bay Trail and surrounding open space throughout Oyster Point Marina and the proposed office/R&D Project (subject to BCDC Guidelines and input) x Enhancement (landscape and other cosmetic improvements) of existing uses at the eastern end of Oyster Point in conjunction with required landfill cap repairs x Connections to the previously permitted Oyster Point Ferry Terminal. The programmatic component of the Project may also include replacement of two docks in the Oyster Point Marina. Although other marina-related activities, such as maintenance dredging, boat refueling, and boating on the Bay are expected to continue, such activities currently occur in the absence of the Project and would continue regardless of Project implementation; thus, these activities are not considered part of the Master Plan analyzed in this document. Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 20105 Phase I Project The first phase (“Phase I”) of the Master Plan will include the development of 508,000 to 600,000 square ft of office/R&D space over a two-level parking garage podium on approximately 10 ac, creation of waterfront open space, construction of the recreation field complex, grading of most of the future hotel site, and construction of new roads serving Oyster Point Marina. The specific details of the Phase I work are outlined below. Demolition Phase I will include demolition of the four existing Oyster Point Inn and Office buildings. Portions of the demolition waste will be salvaged and reused. This Phase of the Project would also include some grading of the old landfill to ensure appropriate drainage, and subsequent recapping. Site and Massing/Building Details Phase I will include the construction of 508,000 to 600,000 square feet of office/R&D space. The new office/R&D buildings will occupy a site of approximately 10 ac to the south of Oyster Point Boulevard directly east of Gull Drive. The office/R&D complex will include three office/lab buildings (Buildings IA, IB and IC) and a retail/restaurant building (Building IR), and will be located on a plaza, which will be built over a two-level parking garage podium. Building IA will have a maximum of 10 levels and 220,000 square ft, while buildings IB and IC will have a maximum of 6 levels and 190,000 square ft each. Levels within these buildings will have a 16-ft typical floor-to-floor height. Internal organization for each building will entail a maximum of 70% lab space and a minimum of 0% lab space (i.e.,. a minimum of 30% office space and a maximum of 100% office space). Building IR will only be one level and will provide 10,000 square ft of retail space located at the plaza level. The two-level parking garage will accommodate a maximum of 1,680 cars, based on a 2.8/1,000 square ft ratio, and will be above grade and open air on the south and east facades. The building entrances and lobbies will be located at plaza level. A shuttle stop and passenger drop off will also be located at plaza level off Oyster Point Boulevard. Access to the parking garage will be through an entrance/exit at the northeastern corner of the garage off of Marina Boulevard. Service entries and loading docks for each building will be accessed at the southwest corner of the site off of Gull Drive. Phase I activities will include grading to install stormwater drainage infrastructure on the site. At the southwestern portion of the site, this drainage will include a conveyance system that will outfall to constructed vegetated swales on the north side of the tidal channel that comprises the southwestern edge of the Project site. Open Space and Infrastructure Improvements on City’s Land (Public Redevelopment) Phase I will include the reconfiguration of Marina Boulevard and a portion of Oyster Point Boulevard. The new roadway construction will also include bicycle lanes, sidewalks and street Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 20106 trees on both sides of the roadway. Utilities will be provided in the new roads and will be sized for the full build-out of all phases (not just Phase I improvements). These will include sewer, water, fire water, and a joint trench for PG&E and telecom. Storm drainage will also be provided. A new shuttle turn-around will be constructed adjacent to the Ferry Terminal, and the parking lot adjacent to the west basin of Oyster Point Marina will be reconstructed after landfill cover improvements have been completed to access the new Marina Boulevard configuration. In addition to the road and utility improvements, additional improvements will be constructed to update the landfill cover to current regulatory requirements (Title 27). Planned recreational elements to be constructed in Phase I include a 3.8-acre site to the east of the office/R&D buildings. This site will be graded to allow for sports fields, which are to be programmed by the City of South San Francisco. A 3.4-acre waterfront site to the north and east of the Oyster Point Boulevard and Marina Boulevard intersection will be graded and landscaped per Bay Conservation and Development Commission (BCDC) design guidelines. Off-street pedestrian paths (including new portions of the Bay Trail) will connect the ferry terminal to the existing Bay Trail, the footbridge to the south of the site, to the eastern edge of the Plaza in Phase I and to Gull Drive to the south of the Phase I buildings. Finally, the 9-acre site to the east of the sports fields will be graded to allow for a future hotel and retail complex. On this site, the Yacht Club structure and the Harbor District garage, yard and surrounding access roads would remain intact throughout Phase I. Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 20107 ENVIRONMENTAL SETTING GENERAL PROJECT AREA DESCRIPTION The Project footprint for the Oyster Point Business Park and Marina Area Redevelopment Master Plan comprises approximately 80 ac of developed, landscaped, coastal salt marsh, and ruderal lands within the City of South San Francisco. The area investigated for biotic resources included the Project footprint and adjacent areas. The area supports a mix of land uses including industry, warehousing, retail, offices, hotels, marinas, and bioscience research and development facilities. While the majority of the Project site comprises developed and landscaped lands, small portions of the Project area feature patches of ruderal grassland, shrubs, and forest; a segment of the Bay Trail, bordered by patches of coastal scrub and marsh vegetation, runs along the edge of the Project area on the southeast, east, and north. The Project site is located near the northeastern edge of the San Mateo peninsula, north of the San Francisco Airport and south of Candlestick Point, where sandstone and greenstone bedrock of the Franciscan formation intergrades with quaternary alluvium of the Santa Clara formation. The Project area is underlain by soils made up of the Urban Land-Orthents, reclaimed complex, 0 to 2 percent slopes (SCS 1991) and water. The Urban Land-Orthents, reclaimed complex is composed of fill soils and landfill materials placed in areas that were once part of San Francisco Bay, as well as silts built up in adjacent tidal flats that support salt marshes. These soils are well drained and have slight to moderate salinity. The typical profile of this soil type can be variable for the top 40 inches, and underlain with silty clay, and clay from 40 to 60 inches. Within areas mapped by SCS (1991) as Urban Land-Orthents, there may be minor components (<2%) of the native Novato and Reyes soils, as well as Orthents cut and fill soil complexes. Elevations on the site range from sea level to approximately 80 ft in the southeastern corner of the site. The National Wetland Inventory (NWI 1985) depicts four wetland or aquatic habitat types on or near the Project footprint: 1) estuarine, subtidal unconsolidated bottom aquatic habitat within the open waters of San Francisco Bay and within the marinas; 2) estuarine, intertidal, emergent wetland, regularly flooded in the marshes to the west of the Oyster Cove Marina; and outside the Project area, 3) estuarine intertidal rocky shore, regularly flooded, along the northern extent of the peninsula to the east of the Oyster Cove Marina; and 4) estuarine, intertidal, unconsolidated shore irregularly flooded along the north shore of Oyster Cove. The mean annual precipitation varies from 15 to 30 inches, and the mean annual temperature ranges from 54-57 degrees Fahrenheit. BIOTIC SURVEYS Prior to conducting field work, H. T. Harvey & Associates ecologists reviewed the Draft Oyster Point Master Plan and Design Guidelines (Shorenstein/SKS 2009); the California Department of Fish and Game’s Natural Diversity Database (CNDDB 2010); recent ecological studies of other projects in the Project vicinity, including the Candlestick Point/Hunters Point Shipyard Project Biological Technical Report (PBS&J 2009) and the South San Francisco Ferry Terminal Draft Environmental Impact Report (San Francisco Bay Area Water Transit Authority 2005); and other Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 20108 technical databases and publications on special-status species in the vicinity, in order to assess the current distribution of special-status plants and wildlife in the Project vicinity. Reconnaissance-level field surveys of the Project site were conducted by H. T. Harvey & Associates on 11 November 2009.The purpose of these surveys was to provide a project- specific impact assessment for Phase I as described above, and a programmatic impact assessment for the remainder of the Project. Specifically, surveys were conducted to: 1) assess existing biotic habitats in the Project area, 2) assess the site for its potential to support special- status species and their habitats, and 3) identify potential jurisdictional habitats such as Waters of the U.S. and riparian habitat. Survey personnel included plant ecologist Kelly Hardwicke, Ph.D. and wildlife ecologist Nellie Thorngate, M.S. K. Hardwicke again visited the site on 12 December 2009 to further refine mapping of coastal salt marsh vegetation. A follow-up visit was conducted on 5 May 2010 by plant ecologist Catherine Roy, M.S., to assess spring conditions and look for suitable habitat for special-status plants that may not have been apparent during the fall surveys and on 17 September 2010 by wildlife ecologist Robin Carle, M.S. to complement the previous reconnaissance-level surveys. BIOTIC HABITATS Seven biotic habitats/land use types occur on the Project site: developed/landscaped, California annual grassland/coyote brush scrub, armored rock levee slope, northern coastal salt marsh, ornamental woodland, sandy beach, and open water. Wherever possible, habitats were described based on Holland’s system of classification (1986), a relatively coarse level of classification based on general species assemblages and broad edaphic characteristics. These habitats are described in detail below, and their distribution both within the Project site and, for certain sensitive habitats, in adjacent areas is shown on Figure 2. Table 1 provides the approximate acreage of each habitat and land use type within the Master Plan boundary. Table 1. Biotic Habitat/Land Use Acreages within the Boundaries of the Oyster Point Business Park and Marina Area Redevelopment Master Plan. Biotic Habitat/Land Use Total Area (ac) Developed/Landscaped57.16 California Annual Grassland/Coyote Brush Scrub 18.90 Armored Rock Levee Slope 1.81 Northern Coastal Salt Marsh 2.47 Ornamental Woodland 0.57 Sandy Beach 0.38 Open Water, Marine 0.27 Total81.56 Developed and Landscaped Vegetation. The Master Plan area includes approximately 57.16 ac of developed and landscaped land uses comprised of hardscaped roads, buildings, parking lot surfaces, paved trail surfaces, ornamental and landscaped areas (typically irrigated with a mulch base), and irrigated turf. The habitat suitability for rare or native vegetation in these areas is very low, and most areas mapped Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 20109 as developed/landscaped are under altered hydrologic regimes, being either dewatered by hardscape or irrigated to support landscaping. The few naturally occurring plants are typical lawn and sidewalk weeds, such as English daisy (Bellis perennis), smooth cat’s ear (Hypochaeris glabra), and yellow sorrel (Oxalis corniculata). All developed areas within the survey area appear to be purposefully and continually maintained, or otherwise are permanently impacted by hardscape and structures. Wildlife. Developed habitats primarily support common, urban-adapted wildlife species, and overall wildlife abundance and diversity are low. Likewise, landscaped habitats are used sparingly by most wildlife species, largely because of the uniform, open nature of most landscaping, and regular disturbances due to landscape maintenance and use. However animals living in adjacent habitats and migratory birds often exploit foraging opportunities offered by landscaped habitats, and dense shrub and tree landscape components may offer sufficient cover for nesting birds and mammals. Common butterflies such as cabbage whites (Pieris rapae) and painted ladies (Vanessa cardui), as well as honeybees (Apismellifera) and other common invertebrate species, are expected to use flowering landscape plants for foraging. Cliff swallows (Petrochelidon pyrrhonota), tree swallows (Tachycineta bicolor), and barn swallows (Hirundo rustica) have been observed at Oyster Point (Sequoia Audubon Society 2001, eBird 2010), and swallows may occasionally nest in the eaves of buildings within the Project area. Black phoebes (Sayornis nigricans) and house finches (Carpodacus mexicanus), which were observed in the Project area during the reconnaissance survey, also likely nest on buildings and under bridges or other structures on or near the Project site. White-crowned sparrows (Zonotrichia leucophrys) and golden-crowned sparrows (Zonotrichia atricapilla) were observed foraging and sheltering in landscape shrubbery in the Project area. Hummingbirds including Anna’s hummingbirds (Calypte anna) and possibly Allen’s hummingbirds (Selasphorus sasin) forage in areas where the landscaping includes flowering plants. Foraging flocks of yellow- rumped warblers (Dendroica coronata) were seen utilizing trees throughout landscaped portions of the Project area. The profusion of trees incorporated into the landscaping in the Oyster Point area host a variety of foraging songbirds throughout the year, and common species such as dark- eyed juncos (Junco hyemalis), northern mockingbirds (Mimus polyglottos), and American robins (Turdus migratorius), all of which were observed on the site during the reconnaissance survey, may nest in landscape shrubs or trees on the Project site. Mexican free-tailed bats (Tadarida brasiliensis) could roost in small numbers in structures that offer crevices or cavities (such as weep holes or vents) for shelter, though likely in low numbers given the relatively cool conditions along the edge of the bay. Small, non-native mammals such as house mice (Mus musculus), eastern gray squirrels (Sciurus carolinensis), and fox squirrels (Sciurus niger) are expected to forage in shrubs and trees in the landscaped potions of the Project area, and invasive Norway rats (Rattus norvegicus) are expected to use landscaping as well as inhabiting storage areas and garbage facilities at least in small numbers. Feral cats (Felis catus) were observed on the Project site, and may shelter in or under buildings and in landscape shrubs in the Project area. Urban-adapted native mammals such as raccoons (Procyon lotor) and striped skunks (Mephitis mephitis) likely occur in this land use type as well. Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201010 California Annual Grassland/Coyote Brush Scrub Vegetation.Approximately 18.90 ac of the Project site are dominated by California annual grassland/coyote brush scrub. This habitat is primarily found south and southwest of Marina Boulevard, with small patches north of Marina Boulevard., and west of the northern coastal salt marsh on the western side of Oyster Point Boulevard. These areas vary in composition based on water availability and soil characteristics. Non-native annual grass species such as wild oats (Avena fatua), rip-gut brome (Bromus diandrus), and mouse barley (Hordeum murinum) are dominant throughout the annual grassland. Annual grasslands along the estuarine canal south of Marina Boulevard, and west of the sandy beach, support dense stands wild oats and wild radish (Raphanus sativa) approximately 2-4 feet in height. Grassland areas bordering the western end of Marina Boulevard have been mown, opening the canopy for herbaceous species such as smooth cat’s ear (Hypochaeris glabra). North of Marina Boulevard there is a patch that is dominated by mouse barley and annual ryegrass (Lolium multiflorum) growing 1-3 ft in height. South of Marina Boulevard near the road, there are patches of grassland with lower densities of annual grasses. Native purple needlegrass, (Nassella pulchra) is becoming establishedhere along with herbaceous species such as birds-foot trefoil (Lotus corniculatus), flax (Linum sp.), and blue eyed grass (Sisyrinchium bellum). However, this patch of native grass is too small to be distinguished as a separate habitat type. Some shrubs such as coyote brush (Baccharispilularis), toyon (Heteromeles arbutifolia), and big saltbush (Atriplex lentiformis) have become established along the slopes above the estuarine canal south of Marina Boulevard. These are spaced sporadically and range in height from approximately 6-8 feet, and are between 5-8 feet wide. Wildlife. The grassland and scrubby habitats within the Project boundaries host a variety of common invertebrates, which in turn provide food for widespread reptiles such as western fence lizards (Sceloporus occidentalis), and for a number of bird and mammal species. A western meadowlark (Sturnella neglecta) and a Say’s phoebe (Sayornis saya) were observed foraging at the southwestern corner of the Project site. Although other grassland-associated species such as white-tailed kites (Elanus leucurus), American kestrels (Falco sparverius), and loggerhead shrikes (Lanius ludovicianus) occur in the Project vicinity (Sequoia Audubon Society 2001, eBird 2010) and may forage in the Project area on occasion, this patch of grassland is likely too small to support nesting pairs of these species. Small mammals and mesocarnivores including house mice, striped skunks, and raccoons may forage in these habitats, and several valley pocket gopher (Thomomys bottae) burrows were observed in the grassland in the southwestern corner of the Project area. Armored Rock Levee Slope Vegetation.Armored rock levee slope covers approximately 1.81 ac within the Project site and extends downslope from the Project boundary in a number of areas. The rock levees surround the Marina Boulevard peninsula and the Project area bordering the water west of Oyster Point Boulevard. This habitat is primarily composed of large rock rip-rap on varying degrees of slope approximately 10-15 ft wide at the edge of the water and tidal flats. Vegetation in this community is only found between the rocks and bordering the top of the slopes. It is dominated Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201011 by non-native species such as wild radish, wild oats, bristly ox-tongue (Picris echioides), and buckthorn plantain (Plantago aristata). North of Marina Boulevard, the rock levee intergrades somewhat with salt marsh species. Plants with higher salt tolerances such as alkali Russian thistle (Salsola soda), sea fig (Carpobrotus sp.), and saltgrass (Distichlis spicata) occur sporadically. The rock levee slope west of Oyster Point Boulevard is steeper than the rock levee surrounding Marina Boulevard. Vegetation in this community is influenced by landscape plantings such as prostrate manzanita (Arctostaphylos sp.), and nasturtium (Tropaeolum majus), which have been planted along the top edges of the rip-rap. Plants growing among the rocks above the high tide line include non-native volunteer species such as New Zealand spinach (Tetragonia tetragonioides), spring vetch (Vicia sativa), and native saltgrass. Wildlife.Armored rock levees such as those along the periphery of the Project area provide limited wildlife habitat because of their unyielding surfaces, lack of vegetation, and proximity to open marine water, but are nonetheless utilized by several species for foraging or refugia. Rocky shore crab species could shelter in crevices between the rocks, foraging on algae that grow there. Rocky shore-associated birds such as black turnstones (Arenaria melanocephala) have been observed foraging occasionally on the rocks at Oyster Point (eBird 2010). The levee slopes also could provide habitat for nuisance species such as Norway rats, black rats (Rattus rattus), and feral cats, which are known to prey upon native wildlife species. Northern Coastal Salt Marsh Vegetation. Approximately 2.47 ac of northern coastal salt marsh occurs in the Project area in strips or larger areas surrounding the rock levees and along the estuarine canal South of Marina Boulevard. In some areas, this marsh continues downslope from the Project boundary. These areas are in the intertidal zone, and are influenced daily by rising and falling tides within the bay. In slightly higher elevation areas of the marshes, natives such as saltgrass and spearscale (Atriplex triangularis) occur with ruderal, non-native species such as brass buttons (Cotula coronopifolia). As the elevation decreases these species give way to a mix of native coastal salt marsh and alkaline-adapted species such as pickleweed (Salicornia virginica), sea lavender (Limonium californicum), and marsh jaumea (Jaumea carnosa). Other common plants in the salt marsh include coast gumweed (Grindelia stricta) and red sand spurry (Spergularia rubra). In frequently inundated areas and some marsh channels, stands of cordgrass (Spartina sp.) have been sprayed through control efforts between the 2009 and 2010 site visits. Therefore, much of the emergent tall grass structure typical of the lowest elevation portions of the marsh was missing from the Project area. The salt marsh southwest of the Oyster Cove Marina off of Oyster Point Boulevard has accumulated sediment and supports a small but productive tidal wetland community. The vegetation here matches that described above but covers a larger, more continuous area. It also supports a suite of bulrushes (Schoenoplectus sp.), rushes (Juncus sp.), and cattails (Typha sp.), which indicate the influence of freshwater from the adjacent drainage. A large population of cordgrass (Spartina sp.) was observed growing in this marsh during the November 2009 site visit. In May 2010 the cordgrass in this marsh was dead, indicating that it too had been controlled through Spartina control efforts. Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201012 Wildlife.Salt marsh habitats form unique ecological communities in the San Francisco Bay that support wildlife species adapted to a saline environment and frequent cyclic changes in water levels, as well as several more widely-adapted common species. The mudflats associated with Bay salt marsh habitats provide shelter for burrowing invertebrates and rich foraging habitats for a plethora of wildlife species. Mallards (Anas platyrhynchos) and snowy egrets (Egretta thula) were observed foraging in the tidal channels in the salt marsh habitat along the southwestern portion of the Project area, as well as roosting higher up in pickleweed beds, and white-crowned sparrows were seen foraging in the highest edges of these salt marshes. Common bird species such as song sparrows (Melospiza melodia), house finches (Carpodacus mexicanus), and American goldfinches (Spinus tristis) that live in adjacent habitats may also forage in the higher portions of these salt marshes on occasion; it is possible that Alameda song sparrows (Melospiza melodia pusillula) could be found here in very low numbers. The mudflats and exposed tidal channels within the Project area are probably used by many of the shorebird species known to occur in the Bay Area; during the reconnaissance surveys, we observed black-bellied plovers (Pluvialis squatarola), willets (Catoptrophorus semipalmatus), California gulls (Larus californicus), western gulls (Larus occidentalis), snowy egrets, western sandpipers (Calidris mauri), black-necked stilts (Himantopus mexicanus), long-billed curlews (Numenius americanus), and whimbrels (Numenius phaeopus) foraging across the flats. Mammals such as rats, striped skunks, and raccoons may forage in the salt marshes in the Project area, but these marshes are too limited in extent, underdeveloped in vegetation, and isolated from known populations to support salt marsh adapted mammal species such as salt marsh harvest mice (Reithrodontomys raviventris) or salt marsh wandering shrews (Sorex vagrans halicoetes). Ornamental Woodland Vegetation. Approximately 0.57 ac of the Project area is dominated by ornamental woodland. This area is located near the southwest corner of the Project site at the intersection of Gull Drive and Marina Boulevard. Blue gum (Eucalyptus globulus) dominates the area with a few Monterey pine (Pinus radiata) interspersed. Vegetation beneath the dense eucalyptus canopy is sparse due to canopy shading and a thick cover of leaf litter. Non-native species such as Himalayan blackberry (Rubus discolor) and French broom (Genista monspessulana) are able to survive in this environment. A few shrubs such as coyote brush, toyon, and coffeeberry (Rhamnus californica) are thriving on the sunnier edges of the woodland along with the non- native pampas grass (Cortaderia jubata). Wildlife. This grove of eucalyptus and Monterey pine trees is likely to host an array of common invertebrate species. The trees and shrubs provide suitable nesting habitat for common birds such as American robins, California towhees (Pipilo crissalis), and dark-eyed juncos. The trees may also support a nest of one of the larger common raptors, such as red-shouldered hawks (Buteo lineatus), red-tailed hawks (Buteo jamaicensis), and great horned owls, all of which breed in the Project vicinity (Sequoia Audubon Society 2001). However, due to the territorial nature of these birds, no more than one nest of one of these species would be expected to occur here. The trees could also be used as roost sites by small numbers of common roosting bats such as California myotis (Myotis californicus). Other mammals, including house mice, striped skunks, and raccoons, are also likely to forage in this area. Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201013 Sandy Beach Vegetation.Sandy beach is present on approximately 0.38 ac within the Project area. This area is located at the edge of the Bay along Marina Boulevard, to the northwest of Oyster Point Marina. This area includes some habitat below the wrack indicating the high tide line as well as beach sands above the high tide line that are not typically inundated. Vegetation on the beach is sparse due to the mostly unconsolidated sand substrate, high drainage, and perpetual sand movement. Typical sandy beach species such as the native beach bur (Ambrosia chamissonis), as well as non-natives such as wild radish and sea fig are becoming established on the upper edges that do not undergo frequent disturbance. This vegetation merges with California annual grassland as the slope rises away from the water. The southern end of the beach is bordered by northern coastal salt marsh vegetation and the northern end is bordered by armored rock levee slope. Wildlife.Sandy beaches, relatively rare within the Bay, are home to intertidal invertebrates that serve as prey for shorebirds and seabirds. Western sandpipers and Brewer’s blackbirds (Euphagus cyanocephalus) were observed during the reconnaissance survey, foraging along the wrack line on the small sandy beach within the Project area. Urban-adapted mammals living in the vicinity are likely to forage opportunistically on the sandy beach; we observed two feral cats on the sandy beach during the reconnaissance survey. Due to the extremely limited extent of the sandy beach on the Project site, beach-nesting birds such as the western snowy plover (Charadrius alexandrinus nivosus), are not expected to occur here. Open Water Vegetation.Open water habitat is present within approximately 0.27 ac of the Project area. However, extensive open water is present in the Oyster Point Marina and the Oyster Cove Marina, as well as the Bay waters surrounding the peninsula within the “Additional Study Area” boundary shown on Figure 2. The area is underlain with unconsolidated bay mud or gravel. The average water depth at the marina averages 5 ft; however, water depth fluctuates due to tidal fluctuation, and is typically shallower around the levees and marshes. The water temperature is cooler than what would be found in estuarine habitats and supports a diversity of algae growing on rocks and piers. Open water habitat is also present within a linear tidal canal south of Marina Boulevard. This habitat is heavily influenced by tidal fluctuations with water depth ranging from approximately 0 to 5 ft. This area has a mud substrate made up of fine silt and clay that supports little vegetation in the main canal. It is bordered on both banks by northern coastal salt marsh habitat that is thickest on the south bank. There is little evidence of significant influence from fresh water tributaries due to the lack of presence of brackish plant species. Wildlife. The San Francisco Bay supports a thriving community of estuarine life. Benthic invertebrates present within open water and intertidal habitats in the Project vicinity include the native Olympia oyster (Ostreola conchaphila). Native Olympia oysters were historically abundant in San Francisco Bay. Currently, populations of native oysters within the Bay are relatively low compared to historical conditions (Harris 2004). Suitable habitat, which consists of solid surfaces to which the larvae can easily attach, is distributed throughout the shoreline of Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201014 the Project area and on the breakwater of the Oyster Point marina, and a population has been documented in these areas (Zabin et al. 2010). A diversity of other invertebrates provide an ample prey base for common fish, which in the Project vicinity may include such species as Pacific herring (Clupea pallasi), Pacific halibut (Hippoglossus stenolepis), Pacific sardine (Sardinops sagax), and anchovies (Anchoa spp.), which in turn provide food sources for seabirds and marine mammals such as harbor seals (Phoca vitulina). California and western gulls, surf scoters (Melanitta perspicillata), scaup (Aythya spp.), eared grebes (Podiceps nigricollis), Clark’s grebes (Aechmophorus clarkii), western grebes (Aechmophorus occidentalis), buffleheads (Bucephala albeola), California brown pelicans (Pelecanus occidentalis), and double-crested cormorants (Phalacrocorax auritus) were observed foraging in the Bay just offshore of the Project site during the reconnaissance survey. During low tide, shorebirds forage on intertidal mudflats here. Fish such as starry flounder (Platichthys stellatus) that are common in estuarine waters around the San Francisco Bay could inhabit the narrow channel of estuarine water within the Project area. Mallards and snowy egrets were observed foraging in the channel during the reconnaissance survey, and other waterbirds are likely to forage in the channel on occasion. Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201015 REGULATORY SETTING Biological resources within the Project site are regulated by a number of federal, state, and local laws and ordinances, as described below. FEDERAL Clean Water Act Areas meeting the regulatory definition of “Waters of the U.S.” (jurisdictional waters) are subject to the jurisdiction of the United States Army Corps of Engineers (USACE) under provisions of Section 404 of the 1972 Clean Water Act (Federal Water Pollution Control Act) and Section 10 of the 1899 Rivers and Harbors Act (described below). These waters may include all waters used, or potentially used, for interstate commerce, including all waters subject to the ebb and flow of the tide, all interstate waters, all other waters (intrastate lakes, rivers, streams, mudflats, sandflats, playa lakes, natural ponds, etc.), all impoundments of waters otherwise defined as “Waters of the U.S.,” tributaries of waters otherwise defined as “Waters of the U. S.,” the territorial seas, and wetlands (termed Special Aquatic Sites) adjacent to “Waters of the U.S.” (33 CFR, Part 328, Section 328.3). Wetlands on non-agricultural lands are identified using the Corps of Engineers Wetlands Delineation Manual (Environmental Laboratory 1987). Areas typically not considered to be jurisdictional waters include non-tidal drainage and irrigation ditches excavated on dry land, artificially-irrigated areas, artificial lakes or ponds used for irrigation or stock watering, small artificial water bodies such as swimming pools, and water- filled depressions (33 CFR, Part 328). Construction activities within jurisdictional waters are regulated by the USACE. The placement of fill into such waters must comply with permit requirements of the USACE. No USACE permit will be effective in the absence of state water quality certification pursuant to Section 401 of the Clean Water Act. The State Water Resources Control Board (SWRCB) is the state agency (together with the Regional Water Quality Control Boards [RWQCBs]) charged with implementing water quality certification in California. Project Applicability. Any work within areas defined as Waters of the U.S. (i.e., wetlands and other waters), including open water and intertidal habitats of San Francisco Bay, the tidal canal at the southern edge of the site, and associated wetlands and shoreline areas (extending up to the high tide line or the upper limits of wetlands, whichever is higher) may require a Section 404 fill discharge permit from the USACE and Section 401 Water Quality Certification from the RWQCB. The approximate upslope limits of USACE jurisdiction under the Clean Water Act are shown on Figure 2. A jurisdictional wetland delineation to determine the precise boundaries of USACE jurisdiction has not been performed for the Project. Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201016 Porter-Cologne Water Quality Control Act The RWQCB is responsible for protecting surface, ground, and coastal waters within its boundaries, pursuant to the Porter-Cologne Water Quality Control Act of the California Water Code. The RWQCB has jurisdiction under Section 401 of the Clean Water Act for activities that could result in a discharge of dredged or fill material to a water body. Federal authority is exercised whenever a proposed project requires a Clean Water Act Section 404 permit from the USACE in the form of a Section 401 Water Quality Certification. State authority is exercised when a proposed project is not subject to federal authority, in the form of a Notice of Coverage, Waiver of Waste Discharge Requirements. Many wetlands fall into RWQCB jurisdiction, including some wetlands and waters that are not subject to USACE jurisdiction. RWQCB jurisdiction of other waters, such as streams and lakes, extends to all areas below the ordinary high water mark. The RWQCB has no formal technical manual or expanded regulations to help in identifying their jurisdiction. The only guidance can be found in Porter-Cologne Water Quality Control Act, Chapter 2 (Definitions), which states, “‘waters of the State’ means any surface water or ground water, including saline waters, within the boundaries of the state.” Under the Porter-Cologne Water Quality Control Act, the SWRCB and the nine regional boards also have the responsibility of granting Clean Water Act National Pollutant Discharge Elimination System (NPDES) permits and waste discharge requirements for certain point-source and non-point discharges to waters. These regulations limit impacts to aquatic and riparian habitats from a variety of urban sources. Project Applicability. As stated above, any Project activities that impact waters of the U.S./State will require 401 Certification and/or a Waste Discharge Requirement from the RWQCB. In the Study Area, these include the same boundaries of aquatic, intertidal, and wetlands/shoreline habitats as described above for areas subject to jurisdiction under the Clean Water Act. Rivers and Harbors Act Section 10 of the Rivers and Harbors Act (1899) 33 U.S.C. 403 regulates the construction of structures, placement of fill, and introduction of other potential obstructions to navigation in navigable waters. Under Section 10 of the Act, the building of any wharfs, piers, jetties, and other structures is prohibited without Congressional approval, and excavation or fill within navigable or tidal waters requires the approval of the Chief of Engineers. The USACE has the authority to issue permits for the discharge of refuse into, or affecting, navigable waters under section 13 of the 1899 Act (33 U.S.C. 407; 30 Stat. 1152). The Act was modified by title IV of P.L. 92-500, October 18, 1972; the Federal Water Pollution Control Act Amendments of 1972 (33 U.S.C. 1341-1345; 86 Stat. 877), as amended, established the NPDES permits. Project Applicability. Within the Project area, all tidally influenced open water and intertidal habitats of San Francisco Bay, the tidal canal at the southern edge of the site, and associated Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201017 wetlands and shoreline areas (extending up to the mean high water line) are subject to USACE jurisdiction under the Rivers and Harbors Act, and any activities affecting these areas would potentially require a Section 10 Letter of Permission. Federal Endangered Species Act The federal Endangered Species Act (FESA) protects listed wildlife species from harm or “take” which is broadly defined as to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, collect, or attempt to engage in any such conduct. Take can also include habitat modification or degradation that directly results in death or injury of a listed wildlife species. An activity can be defined as “take” even if it is unintentional or accidental. Listed plant species are provided less protection than listed wildlife species. Listed plant species are legally protected from take under the FESA only if they occur on federal lands or if the project requires a federal action, such as a Clean Water Act Section 404 fill permit from the USACE. The U. S. Fish and Wildlife Service (USFWS) has jurisdiction over federally listed threatened and endangered wildlife species under the FESA, while the National Marine Fisheries Service (NMFS) has jurisdiction over federally listed, threatened and endangered, marine and anadromous fish. Project Applicability. Several federally listed species occur in the general vicinity of the Project site. Although only limited habitat for such species occurs in the Project area, federally listed animal species that occur, or could potentially occur, in the Project area include the green sturgeon (Acipenser medirostris), Central California Coast steelhead (Oncorhynchus mykiss), and California least tern (Sterna antillarum browni), and possibly several Central Valley- breeding salmonids. Magnuson-Stevens Fishery Conservation and Management Act The Magnuson-Stevens Fishery Conservation and Management Act governs all fishery management activities that occur in federal waters within the United States’ 200-nautical-mile limit. The Act establishes eight Regional Fishery Management Councils responsible for the preparation of fishery management plans to achieve the optimum yield from U.S. fisheries in their regions. These councils, with assistance from the NMFS, establish Essential Fish Habitat (EFH) in fishery management plans for all managed species. Federal agencies that fund, permit, or implement activities that may adversely affect EFH are required to consult with the NMFS regarding potential adverse effects of their actions on EFH, and respond in writing to recommendations by the NMFS. Project Applicability.A number of fish species regulated by the Coastal Pelagics and Pacific Groundfish Fisheries Management Plans occur in tidal habitats of San Francisco Bay, including the open water habitats on and adjacent to the Project site. Thus, these tidal waters are considered EFH. Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201018 Marine Mammal Protection Act The Marine Mammal Protection Act (MMPA) was enacted in 1972 and amended through 2007 (16 USC 1631). All marine mammals are protected by the MMPA, which prohibits their take in U.S. Waters. Take is defined in the MMPA as “harass, hunt, capture, kill or collect, or attempt to harass, hunt, capture, kill or collect” [16 USC 1631 Section 3(13)]. Project Applicability. The only two marine mammal species that have potential to occur in the Project vicinity at all regularly are the harbor seal and the California sea lion (Zalophus californianus), both of which may occasionally forage in Bay waters near the site. The MMPA would apply to the Project, because in-water construction activities such as pile driving could potentially harass these animals. Federal Migratory Bird Treaty Act The federal Migratory Bird Treaty Act (MBTA; 16 U.S.C., §703, Supp. I, 1989) prohibits killing, possessing, or trading of migratory birds except in accordance with regulations prescribed by the Secretary of the Interior. The trustee agency that addresses issues related to the MBTA is the USFWS. Migratory birds protected under this law include all native birds and certain game birds (e.g., turkeys and pheasants; Federal Register 70(2):372-377). This act encompasses whole birds, parts of birds, and bird nests and eggs. The MBTA protects active nests from destruction and all nests of species protected by the MBTA, whether active or not, cannot be possessed. An active nest under the MBTA, as described by the Department of the Interior in its 16 April 2003 Migratory Bird Permit Memorandum, is one having eggs or young. Nest starts, prior to egg laying, are not protected from destruction. Project Applicability.All native bird species occurring in the Study Area are protected by the MBTA. STATE California Endangered Species Act The California Endangered Species Act (CESA, Fish and Game Code of California, Chapter 1.5, Sections 2050-2116) prohibits the take of any plant or animal listed or proposed for listing as rare (plants only), threatened, or endangered. In accordance with the CESA, the CDFG has jurisdiction over state-listed species. The CDFG regulates activities that may result in “take” of individuals listed under the Act (i.e., “hunt, pursue, catch, capture, or kill, or attempt to hunt, pursue, catch, capture, or kill”). Habitat degradation or modification is not expressly included in the definition of “take” under the Fish and Game Code. The CDFG, however, has interpreted “take” to include the “killing of a member of a species which is the proximate result of habitat modification.” Project Applicability. Although habitat suitability in the Project area for these species is marginal, State-listed animal species that occur, or could potentially occur, in the Project area include the longfin smelt (Spirinchus thaleichthys) and California least tern. Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201019 California Environmental Quality Act The California Environmental Quality Act (CEQA) is a state law that requires state and local agencies, such as the City of San José, to document and consider the environmental implications of their actions and to refrain from approving projects with significant environmental effects if there are feasible alternatives or mitigation measures that can substantially lessen or avoid those effects. CEQA requires the full disclosure of the environmental effects of agency actions, such as approval of a general plan update or the projects covered by that plan, on resources such as air quality, water quality, cultural resources, and biological resources. The State Resources Agency promulgated guidelines for implementing CEQA known as the State CEQA Guidelines. CEQA and the CEQA Guidelines provide guidance in evaluating impacts of projects to biological resources and determining which impacts will be significant. CEQA defines “significant effect on the environment” as “a substantial adverse change in the physical conditions which exist in the area affected by the proposed project.” Under CEQA Guidelines section 15065, a project's effects on biotic resources are deemed significant where the project would: “substantially reduce the habitat of a fish or wildlife species” “cause a fish or wildlife population to drop below self-sustaining levels” “threaten to eliminate a plant or animal community” “reduce the number or restrict the range of a rare or endangered plant or animal” In addition to the section 15065 criteria that trigger mandatory findings of significance, Appendix G of the CEQA Guidelines provides a checklist of other potential impacts to consider when analyzing the significance of project effects. The impacts listed in Appendix G may or may not be significant, depending on the level of the impact. For biological resources, these impacts include whether the project would: “have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Service” “have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, regulations or by the California Department of Fish and Game or U.S. Fish and Wildlife Service” “have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act” “interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites” “conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance” Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201020 “conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan” Section 15380(b) of the CEQA Guidelines provides that a species not listed on the federal or state lists of protected species may be considered rare if the species can be shown to meet certain specified criteria. These criteria have been modeled after the definitions in the FESA and the CESA and the section of the California Fish and Game Code dealing with rare or endangered plants or animals. This section was included in the guidelines primarily to deal with situations in which a public agency is reviewing a project that may have a significant effect on a species that has not yet been listed by either the USFWS or CDFG or species that are locally or regionally rare. The CDFG has produced three lists (amphibians and reptiles, birds, and mammals) of “species of special concern” that serve as “watch lists”. Species on these lists are of limited distribution or the extent of their habitats has been reduced substantially, such that threat to their populations may be imminent. Thus, their populations should be monitored. They may receive special attention during environmental review as potential rare species, but do not have specific statutory protection. All potentially rare or sensitive species, or habitats capable of supporting rare species, are considered for environmental review per the CEQA § 15380(b). The CNPS, a non-governmental conservation organization, has developed lists of plant species of concern in California. Vascular plants included on these lists are defined as follows: List 1A Plants considered extinct. List 1B Plants rare, threatened, or endangered in California and elsewhere. List 2 Plants rare, threatened, or endangered in California but more common elsewhere. List 3 Plants about which more information is needed - review list. List 4 Plants of limited distribution-watch list. These CNPS listings are further described by the following threat code extensions: .1—seriously endangered in California; .2—fairly endangered in California; .3—not very endangered in California. Although the CNPS is not a regulatory agency and plants on these lists have no formal regulatory protection, plants appearing on List 1B or List 2 are, in general, considered to meet the CEQA’s Section 15380 criteria, and adverse effects to these species may be considered significant. Impacts to plants that are listed by the CNPS on List 3 or 4 are also considered during CEQA review, although because these species are typically not as rare as those on List 1B or List, impacts to them are less frequently considered significant. Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201021 Project Applicability. All impacts to biological resources will be considered during CEQA review of the Project in the context of this EIR. California Fish and Game Code The California Fish and Game Code includes regulations governing the use of, or impacts to, many of the state’s fish, wildlife, and sensitive habitats. The CDFG exerts jurisdiction over the bed and banks of rivers, lakes, and streams according to provisions of §§1601–1603 of the Fish and Game Code. The Fish and Game Code requires a Streambed Alteration Agreement for the fill or removal of material within the bed and banks of a watercourse or waterbody and for the removal of riparian vegetation. Certain sections of the Fish and Game Code describe regulations pertaining to certain wildlife species. For example, Fish and Game Code §§3503, 2513, and 3800 (and other sections and subsections) protect native birds, including their nests and eggs, from all forms of take. Disturbance that causes nest abandonment and/or loss of reproductive effort is considered “take” by the CDFG. Raptors (i.e., eagles, falcons, hawks, and owls) and their nests are specifically protected in California under Fish and Game Code §3503.5. Section 3503.5 states that it is “unlawful to take, possess, or destroy any birds in the order Falconiformes or Strigiformes (birds of prey) or to take, possess, or destroy the nest or eggs of any such bird except as otherwise provided by this code or any regulation adopted pursuant thereto.” Non-game mammals are protected by Fish and Game Code §4150, and other sections of the Code protect other taxa. Project Applicability. All native bird and mammal species that occur in the Project area are protected by the state Fish and Game Code. Because no non-tidal creeks are present in the Project area, it is unlikely that a Streambed Alteration Agreement would be required for Project activities. REGIONAL McAteer-Petris Act The McAteer-Petris Act created the San Francisco Bay Conservation and Development Commission (BCDC) in 1965. BCDC’s mission is to preserve the San Francisco Bay from unregulated filling. BCDC has prepared a comprehensive study of the Bay and determined how future development of the Bay should occur, resulting in the production of the San Francisco Bay Plan in 1968. BCDC’s jurisdiction includes all areas below the mean high tide line and an area within a shoreline band that extends landward for 100 feet from the mean high tide line. The McAteer-Petris Act includes a permitting process for projects that would place fill in, on, or over any part of BCDC’s jurisdiction. Project Applicability. Portions of the Project in, on, or over the Bay, including areas within 100 feet of the mean high tide elevation (or, in areas supporting coastal wetlands, within 100 feet of the mean high tide elevation plus 5 feet), are within BCDC’s jurisdiction, and BCDC approval of any activities within these areas would be required. Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201022 City of South San Francisco Tree Preservation Ordinance Under Chapter 13.30 of the South San Fancisco Municipal Code, the City of South San Francisco maintains a tree preservation ordinance designed to: (a) Provide standards and requirements for the protection of certain large trees (trees with a circumference of 48 inches or greater at 54 inches above the natural grade) and trees and stands with unique characteristics (having been so designated by the director); (b) Provide standards and requirements for planting and maintenance of trees for new development; and (c) Establish recommended standards for planting and maintaining trees on property that is already developed. This chapter achieves these objectives in ways that support and encourage the reasonable economic enjoyment of private property, not in ways that prevent it. (Ord. 1271 § 1 (part), 2000: Ord. 1060 § 1 (part), 1989). Protected trees are not to be removed or pruned without a permit from the City, and must be protected from development-related impacts such as soil compaction and underground trenching for utilities. Additionally, new developments must conform to a series of tree planting requirements. Project Applicability. No trees of protected size or that were known to be protected by special designation from the City director (as demarcated by a fence) were found to occur on-site. As the Oyster Point Business Park will be located in an areas designated as community commercial, business commercial, coastal commercial, office or business and technology park, one landscape tree must be planted for every 2000 square feet of new floor area. SPECIAL-STATUS SPECIES AND SENSITIVE HABITATS CEQA requires assessment of the effects of a project on species that are “threatened, rare, or endangered”; such species are typically described as “special-status species”. For the purpose of environmental review of the Project, special-status species have been defined as described below. Impacts to these species are regulated by some of the federal, state, and local laws and ordinances described under “Regulatory Setting” above. For purposes of this analysis, “special-status” plants are considered plant species that are: x Listed under the FESA as threatened, endangered, proposed threatened, proposed endangered, or a candidate species. x Listed under the CESA as threatened, endangered, rare, or a candidate species. x Listed by the CNPS as rare or endangered on Lists 1A, 1B, 2, 3, or 4. For purposes of this analysis, “special-status” animals are considered animal species that are: Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201023 x Listed under the FESA as threatened, endangered, proposed threatened, proposed endangered, or a candidate species. x Listed under the CESA as threatened, endangered, or a candidate threatened or endangered species. x Designated by the CDFG as a California species of special concern. x Listed in the California Fish and Game Code as a fully protected species (birds at §3511, mammals at §4700, reptiles and amphibians at §5050, and fish at §5515). Figures 3 and 4 depict the CNDDB-mapped records of plants and wildlife, respectively, in the vicinity of the Project area. These generalized maps are valuable on a historical basis, and show areas where special-status species occur or have occurred previously. Special-status Plant Species Information concerning threatened, endangered or other special-status species that may occur in the Project area was collected from several sources and reviewed by H. T. Harvey & Associates’ biologists. These sources included the CNDDB (2010), the Online Inventory of Rare and Endangered Vascular Plants of California (CNPS 2010), The Jepson Manual, Higher Plants of California (Hickman 1993), CalFlora (2010), the Consortium of California Herbaria (2010), and other information available through the USFWS, CDFG, and technical publications. The specific habitat requirements and the locations of known occurrences of each special-status species were the principal criteria used for inclusion in the list of species potentially occurring on the site. We conducted a search of CNDDB Rarefind published accounts (CNDDB 2010) for all special- status species within the USGS Topographic quadrangle maps containing the Project site (principally San Francisco South, although the eastern tip of the peninsula lies along the boundary of the Hunter’s Point quadrangle), and within the five landside quadrangles surrounding these quadrangles, which include: San Francisco North, Oakland West, Point Bonita, Montara Mountain, and San Mateo. For plants, we reviewed all species on current CNPS Lists 1A, 1B, 2, 3 occurring in any of the seven USGS 7.5-minute quadrangles listed above. A typical nine-quadrangle search was not feasible, as no land-containing quadrangles are located to the west. We also considered the list for San Mateo County as CNPS does not maintain quadrangle-level records on List 4 species. Reconnaissance-level surveys were conducted on 11 November and 12 December 2009 and 5 May 2010 for special-status plants and for habitats capable of supporting these species. The CNPS identifies 89 special-status plant species as potentially occurring in at least one of the seven quadrangles containing or surrounding the Project site or, for List 4 species, in San Mateo County. Most of these have a low likelihood of occurrence within the Project area due to the following reasons: lack of specific edaphic requirements on site for the species in question, the species is known to be extirpated from the area, the site is outside the highly endemic range of the species in question, the elevation range of the species is outside of the range on site, or Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201024 degraded habitat conditions on site are not likely to support the species in question. Of the 89 plant species considered, only six were considered to have enough potential for occurrence in the Project vicinity, based on proximity to locally documented populations mapped by the CNDDB and similar habitat requirements to those on site, to be considered in detail. Appendix A lists the plants that were rejected for consideration and the reasons for rejection. The six special-status plant species considered to have some potential for occurrence on the Project site were reviewed in depth and are listed in Table 2. Those species listed as Threatened or Endangered by the state or federal Endangered Species Acts, or considered rare by the CNPS, are discussed in detail below.Of the six species considered in this assessment, none were ultimately determined to have potential to occur on-site after careful consideration of the site’s habitats. Federal or State Endangered or Threatened Species White-rayed pentachaeta (Pentachaeta bellidiflora). Federal Listing Status: Endangered; State Listing Status: Endangered; CNPS List: 1B.1. This annual herb in the composite (Asteraceae) family occurs in cismontane woodlands and valley and foothill grassland habitats at elevations of approximately 115 - 2050 ft (CNPS 2010). When occurring in grassy habitats, this species is often found on serpentine-derived substrates, scoring a 2.4 (weak indicator) in affinity to serpentine soils (CalFlora 2010). The blooming period extends from March to May. White- rayed pentachaetawas known from 12 USGS 7.5-minute quadrangles in Marin, Santa Cruz, and San Mateo counties, but is now presumed extirpated from all historical locations except those in the Woodside quadrangle in San Mateo County. All of the previously known occurrences in other quadrangles were lost to development, making this a major threat for the species. The species is now known from fewer than 20 occurrences, as the Monterey County occurrence once attributed to this species is actually P. exilis var. aeolica (CNPS 2010). The CNDDB lists two occurrences within either the Project quadrangle or eight surrounding quadrangles. One occurrence off of Skyline Boulevard, above San Andreas Lake in San Mateo County indicates that available habitat has been lost due to the presence of a road. Both occurrences are documented as being extirpated or possibly extirpated. CalFlora (2010) has records of five reported occurrences in San Mateo County from as recent as 1994. Recent occurrences are in the serpentinite soils of Edgewood Park. It is unlikely that the fill soils in the Project area would support serpentinite species or are sufficiently rocky. Additionally, this species is only known to occur at elevations outside the elevation range within the Project area. Based on the distance from the nearest documented populations and the quality of on-site soils, this species is presumed absent from the Project area. CNPS-listed Species Coastal marsh milk-vetch (Astragalus pycnostachyus var. pycnostachyus). Federal Listing Status: None; State Listing Status: None; CNPS List: 1B.2. Coastal marsh milk-vetch is a perennial herb in the legume family (Fabaceae) that blooms from April to October.

Coastal marsh milk-vetch is a California endemic occurring in 15 USGS quadrangles in Humboldt, Mendocino, Marin, and San Mateo counties (CNPS 2010). The CNDDB has two documented occurrences within San Mateo County, last seen in 1902. Both of these populations are presumed extant. CalFlora (2010) documents or reports four occurrences dating from as recent as 2007 in San Mateo County. One occurrence in 2004 cites the location of a population of around 200 individuals in coastal bluff, estuarine flat, and constructed levee locations and in other occurrences it was found in marsh and dune habitats. Based on the recent documentation of the species in San Mateo County, and the occurrence in salt marsh habitat, and levees, suitable habitat occurs within the Project area. However, all known occurrences are located on the Pacific coastline, not within San Francisco Bay, so it is not expected that any extant populations could serve as seed sources for this species within the Project area, and the species is presumed absent. Pale yellow hayfield tarplant (Hemizonia congesta ssp. congesta). Federal Listing Status: None; State Listing Status: None; CNPS List: 1B.2. Pale yellow hayfield tarplant is an annual herb of the sunflower family (Asteraceae) that is native and endemic to the state of California. It is sometimes found on serpentine soil and is typically found in coastal grassland and sometimes roadsides. The blooming period for the species extends from April to November and occurs at elevations between 0-1000 ft.This species is known to occur in Mendocino, Marin, San Francisco, San Mateo, and Sonoma counties (CNPS 2010). The CNDDB has only 2 documented occurrences of pale yellow hayfield tarplant since 1909 within the Project quadrangles and surrounding quadrangles. These are thought to be extirpated or extant due to alteration from urban development. Due to the documented ability of the species to exist in disturbed habitats, and the presence of grassland habitat on site, marginally suitable grassland habitat exists for this species on site. However, as the only documented occurrences are found near the summit of San Bruno Mountain, too far to serve as source populations for the species on site, hayfield tarplant is considered absent from the Project Area. Saline clover (Trifolium depauperatum var. hydrophilum). Federal Listing Status: None; State Listing Status: None; CNPS List: 1B.2. Saline clover is an annual herb in the legume family (Fabaceae) that occurs in mesic, alkaline, or saline sites in valley and foothill grassland habitat, in vernal pool habitat, or in marshes and swamps at elevations from 0 to 984 ft. Hickman (1993) specifically indicates that the species occurs in coastal salt marshes as well as inland marshes. The blooming period extends from April through June, although in salt marshes the species may flower slightly later than seen in alkaline grassland areas. The range of this species has been reduced to remaining alkaline grasslands in Alameda, Colusa, San Mateo, Monterey, Napa, San Luis Obispo, San Benito, Santa Clara, Solano, Sonoma, and Santa Cruz counties. The species is documented from 22 USGS 7.5-minute quadrangles. Many occurrences of the species have likely been extirpated; the species is threatened by development, trampling, road construction, and vehicles (CNPS 2010). The CNDDB lists two records of saline cloveroccurring in San Mateo County in marshes, swamps, valley and foothill grassland or vernal pools. However, the Jepson Interchange (2010) suggests the possibility that the species is locally extinct. Due to the rarity of this species, the Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201037 lack of a nearby source population, and the long history of disturbance of the Project site, it is presumed absent. San Francisco owl’s-clover (Triphysaria floribunda). Federal Listing Status: None; State Listing Status: None; CNPS List: 1B.2.San Francisco owl’s-clover is an annual herb in the figwort family (Scrophulariaceae) that is documented from nine USGS 7.5-minute quadrangles in the counties of Marin, San Francisco, and San Mateo. It is usually found on serpentinite soils in coastal prairie, coastal scrub, and valley and foothill grassland habitats at elevations from 33 to 525 ft. It blooms from April to June and is threatened by grazing, trampling, and competition (CNPS 2010). The CNDDB lists eight documented occurrences of San Francisco owl’s clover within the Project site quadrangle or the eight surrounding quadrangles. It was last seen in the Project vicinity in the 1960s. It is unlikely that the fill soils onsite would be suitable habitat for the species since it is typically associated with serpentine soils. Due to the lack of any recent records in the Project vicinity, the long history of disturbance of the Project site, and the marginal nature of habitat on the site, this species is presumed absent. Large-flowered leptosiphon (Leptosiphon grandiflorus; formerly Linanthus grandiflorus). Federal Listing Status: None; State Listing Status: None; CNPS List: 4.2. Large-flowered leptosiphon is an annual herb in the phlox family (Polemoniaceae) found on sandy soils in coastal bluff scrub, closed-cone coniferous forest, cismontane woodland, coastal dunes, coastal prairie, coastal scrub, and valley and foothill grassland habitats. It occurs within Alameda, Kern, Madera, Merced, Monterey, Marin, Santa Clara, Santa Cruz, San Francisco, San Luis Obispo, San Mateo, and Sonoma counties. It is considered to be extirpated from Santa Barbara County. The blooming period for this species is April through August at elevations from 16 to 3674 ft. Many historical occurrences have been extirpated by development (CNPS 2010). There is limited documentation for this species in San Mateo County. CALFLORA (2010) has one documented occurrence in San Mateo County in 1961. The CNPS suggests that the species prefers sandy soils. However, it is known to inhabit a wide variety of habitats over a broad range in California. There are no sufficiently undisturbed habitats on-site, and areas approximating the habitat conditions of known occurrence locations in coastal bluff scrub or dunes or mesic coastal prairies are not present. Therefore, this species is presumed absent. Special-status Animal Species Reconnaissance-level field surveys of the Project site were conducted on 11 November 2009 and 17 September 2010 to assess the site’s potential for supporting special-status wildlife species. Additional information regarding the occurrence of special-status wildlife species in the Project area was obtained from previous H. T. Harvey & Associates projects performed in the vicinity. The legal status and likelihood of occurrence of special-status wildlife species known to occur, or potentially occurring, in the general Project vicinity are presented in Table 2. Figure 4 depicts the CNDDB-mapped locations of special-status animals in the Project vicinity. Several of the special-status species listed in Table 2 are not expected to occur in the Project area because the site lacks suitable habitat, is outside the distributions of the species, and/or is isolated Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201038 from the nearest known extant populations by development or otherwise unsuitable habitat. For instance, several federally endangered butterfly species are known to occur (or to have occurred historically) in the vicinity, primarily on Mount San Bruno to the northwest of the site; these include the Bay checkerspot butterfly (Euphydryas editha bayensis), callippe silverspot (Speyeria callipe callippe), mission blue butterfly (Plebejus icarioides missionensis), Myrtle’s silverspot (Speyeria zerene myrtleae), and San Bruno elfin (Callophrys mossii bayensis). However the site does not support any of the host plants required by these species, and is outside of their currently known distributions. Other species not expected to occur in the Project area for the reasons outlined above include the white abalone (Haliotes sorenseni), tidewater goby (Eucyclogobius newberryi), coho salmon (Oncorhynchus kisutch), California tiger salamander (Ambystoma californiense), western pond turtle (Actinemys marmorata), marbled murrelet (Brachyramphus marmoratus), Townsend’s big-eared bat (Corynorhinus townsendii), pallid bat (Antrozous pallidus), salt marsh harvest mouse, salt marsh wandering shrew, and San Francisco dusky-footed woodrat (Neotoma fuscipes annectens). Several other special-status species are expected to occur in the Project area only as uncommon to rare visitors, migrants, or transients, or may forage on the site while breeding in adjacent areas. However, these species are not expected to breed in the Project area in any numbers, or to be affected by Project implementation. Several Central Valley fish species, including the river lamprey (Lampetra ayresii), Central Valley steelhead (Oncorhynchus mykiss), and Sacramento River Winter-run and Central Valley Spring-run Chinook salmon (Oncorhynchus tshawytscha) occur regularly in the Delta and in the San Joaquin and Sacramento rivers, and occasional individuals could conceivably drift into the Project area during migration between those areas and the Golden Gate. However, we do not expect these species to occur with any regularity near the Project area, and they are not expected to be affected by Project activities. Other species expected to occur only as occasional visitors include the American peregrine falcon (Falco peregrinus anatum), black skimmer (Rynchops niger), harlequin duck (Histrionicus histrionicus), northern harrier (Circus cyaneus), Vaux’s swift (Chaetura vauxi), yellow warbler (Dendroica petechia), and tricolored blackbird (Agelaius tricolor). A number of other special-status wildlife species are known or expected to occur regularly on or near the Project site and may breed there, or are species for which resource agencies have expressed particular concern; expanded discussions of these species follow. Federal or State Threatened or Endangered Species Central California Coast steelhead. Federal Listing Status: Threatened; State Listing Status: Species of Special Concern. The Central California Coast Distinct Population Segment (DPS) of steelhead was listed as federally threatened in 1998 (NMFS 1998), and critical habitat was designated in 2005 (NMFS 2005).The Project site is within critical habitat boundaries for the Central California Coast DPS. Steelhead, the anadromous form of rainbow trout, occur in most perennial, free-flowing coastal streams in central and northern California where the water temperature does not exceed 70°F. The Central California Coast steelhead ranges from the Russian River south to Aptos Creek and includes the populations within San Francisco Bay (Moyle 2002). In central California, adult steelhead migrate upstream to spawn from early winter to mid-spring, after winter storms provide sufficient flows to facilitate migration to Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201039 spawning grounds. Spawning occurs between December and June, typically in gravelly substrates free of fine sediments, roots, and emergent vegetation.Preferred streams typically support a dense canopy cover that provides shade, woody debris, and organic matter. Most young steelhead remain in freshwater for 1 to 2 years in cool, clear streams with brisk currents, more riffles than pools, and abundant riparian cover, before they become smolt and enter the ocean (Moyle 2002). Streambed degradation, alteration, and blockages have significantly reduced steelhead habitat, and this reduction, as well as reduced genetic diversity and climate change, has seriously impacted Central Coastal California steelhead populations (Busby et al. 1996). The closest potential steelhead spawning streams in South San Francisco Bay are San Mateo Creek (approximately 7 mi south of the Project area), Alameda Creek (approximately 14 miles southeast of the Project area), and San Francisquito Creek (approximately 20 miles south of the Project area). Other South Bay watersheds farther south also support populations of steelhead. Because the Project area is between their spawning and rearing streams and the Pacific Ocean, fish from any of these streams could be found in the Bay adjacent to the Project site during adult migrations from the Pacific Ocean to spawning sites or during juvenile migrations from their natal streams to the Pacific Ocean. Southern green sturgeon (Acipenser medirostris). Federal Listing Status: Threatened; State Listing Status: None. The southern DPS of green sturgeon was listed as threatened by the NMFS on April 7, 2006 (NMFS 2006a), and critical habitat was designated in October 2009 (NMFS 2009). Critical habitat for the green sturgeon includes all of San Francisco Bay. The green sturgeon is a long-lived, anadromous, native fish that occurs in low numbers in the San Francisco Estuary and Sacramento River. Adults spawn in freshwater rivers from British Columbia south to the Sacramento River. Larvae develop within these freshwater systems, migrate downstream, and remain in the estuaries for between 1 and 4 years before migrating to the ocean. Mature adults move into estuaries in the spring and spawning adults move up the rivers of their origins in late spring/early summer. Post spawning adults return to the estuary before migrating back to the ocean in late fall. Sub-adult fish also are thought to enter estuaries during summer and fall months. The Project area does not support the necessary freshwater spawning habitat for adult sturgeon, but individuals could occasionally wander into the portion of San Francisco Bay adjacent to the Project site, where they may forage, and juvenile fish and sub-adults may rear in the adjacent waters of San Francisco Bay in small numbers. Longfin smelt (Spirinchus thaleichthys). Federal Listing Status: Threatened; State Listing Status: None.Longfin smelt were listed under the California Endangered Species Act as a threatened species in 2009. This species is endemic to the west coast of North America with small populations likely still present in the Klamath River and Russian River estuaries (Moyle 2002). However, the bulk of the longfin smelt population appears to be in San Francisco Bay. Adults spawn primarily in the Sacramento-San Joaquin Estuary almost as far upstream as the City of Sacramento on the Sacramento River and to Turner Cut on the San Joaquin River. Adults spawn in these upstream freshwater locations in early winter. The larval smelt are Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201040 distributed downstream by natural river flow. As they mature, swimming ability improves and their distribution expands. Although the bulk of this species’ population apparently spawns in the Delta region, the species also likely spawns in freshwater waters elsewhere in the Bay Area, including streams in the South Bay. No suitable spawning habitat is present on or very near the Project site, but small numbers of this species could be found in Bay waters adjacent to the Project area as individuals disperse and feed in the Bay. California red-legged frog (Rana draytonii). Federal Listing Status: Threatened; State Listing Status: Species of Special Concern. The California red-legged frog is generally restricted to riparian and lacustrine habitats in California and northern Baja California. Red- legged frogs prefer deep, calm pools (usually more than 2 ft deep) in creeks, rivers, or lakes below 5000 ft in elevation (Jennings and Hayes 1994). Breeding habitat requirements include freshwater emergent or dense riparian vegetation, such as willows adjacent to shorelines. Red- legged frogs can survive in seasonal bodies of water that are dry for short periods if a permanent water body or dense vegetation stands are nearby. Adult red-legged frogs are normally active at night and breed in still water during the late winter or early spring after waters recede. Females attach eggs in a single cluster to vegetation just under the surface of the water. The eggs hatch in approximately one week and larvae feed on plant and animal material. It takes a minimum of approximately 4 months for the larvae to metamorphose into juvenile frogs. On rare occasions larvae over winter. Red-legged frogs can move considerable distances overland. Dispersal often occurs within creek drainages, but movements of more than a mile over upland habitats have been reported (Bulger et al. 2003). Red-legged frogs are often found in summer months in habitat that would not be suitable for breeding; these individuals presumably move seasonally between summer foraging habitat and winter breeding habitat. The USFWS listed the California red-legged frog as threatened in 1996, due to continued habitat degradation throughout the species’ range and population declines. Critical habitat was most recently designated for the California red-legged frog in 2010 (USFWS 2010), but this critical habitat designation does not include the Project area. The population of red-legged frogs closest to the Project site occurs in a wetland at the edge of tidal influence, to the west of Highway 101 next to the San Francisco Airport, approximately 3.5 mi south of the Project area (CNDDB 2010). This and other more distant populations in the Project vicinity are separated from the Project area by extensive development and substantial barriers including Highway 101. The Project site does not support fresh pools, streams, or ponds, and the existing tidal marshes within the Project area are saline. Therefore we do not expect this species to occur on the Project site. San Francisco garter snake (Thamnophis sirtalis tetrataenia). Federal Listing Status: Endangered; State Listing Status: Endangered and Fully Protected. The San Francisco garter snake was listed as endangered by the U.S. Fish and Wildlife Service in 1967 (USFWS 1976). Critical habitat has not been designated for this species.The historic distribution of the Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201041 San Francisco garter snake extended from the southern San Francisco County line to Año Nuevo in southern San Mateo County. While the current distribution is likely similar, populations have declined within the range, and have become increasingly fragmented due to habitat alteration in the region (Brode et al. 1994). The San Francisco garter snake frequents wetlands and grasslands with dense vegetation cover near ponds or streams, though they have been known to make use of less suitable habitat (USFWS 2007). Additionally, San Francisco garter snakes require some upland habitat with burrows or interstitial spaces for basking and aestivation, and suitable habitat must support a prey base of species such as red-legged frogs, pacific chorus frogs (Pseudacris regilla), and western toads (Bufo boreas). The San Francisco garter snake is a live- bearing reptile, and young are born in late summer (Brode et al. 1994). The San Francisco garter snake continues to be threatened by increasing habitat loss and degradation, as well as illegal collecting by reptile fanciers (USFWS 2007). The nearest known population of San Francisco garter snakes occurs in a wetland to the west of Highway 101 next to the San Francisco Airport, approximately 3.5 mi south of the Project area (CNDDB 2010). This and other more distant populations in the Project vicinity are separated from the Project area by extensive development and substantial barriers including Highway 101. The Project site does not support freshwater marshes, and the saltmarshes within the Project boundaries do not support a sufficient amphibian prey base for garter snakes. Therefore we do not expect the species to occur on the Project site. California black rail (Laterallus jamaicensis coturniculus). Federal Listing Status: None; State Listing Status: Threatened and Fully Protected. Historically, black rails ranged along the Pacific coast from Tomales Bay in the north to northern Baja California in the south, but comprehensive and ongoing habitat loss has reduced their distribution and abundance considerably, leading to their state status as a fully protected and threatened bird (Evens et al. 1991, Eddleman and Evens 1994). The current range of the California black rail is restricted primarily to the tidal marshes of the northern San Francisco Bay, with small localized populations also occurring in the southern portion of the bay, in Marin County, in the foothills of the western Sierra Nevada, and in the Colorado River area (Spautz et al. 2005). It is estimated that up to 90% of habitat in California, and at least 85% of San Francisco salt-marsh habitat, has been degraded or destroyed, mostly due to agriculture and development. The vast majority of California black rails frequent tidal marshes with quantities of low, dense, emergent vegetation, while the few remaining inland rail populations are associated with shallow, stable freshwater marshes dominated by fine-stemmed vegetation. Prime black rail habitat features large, contiguous stretches of stable tidal marsh dominated by pickleweed (Salicornia spp), Scirpus spp, or cattails, with low levels of urban development (Spautz et al. 2005). Rails begin nesting in late February, constructing well-hidden cup nests low to the ground near the high flood line. They nest through July, after which juveniles disperse erratically; adults remain on their breeding grounds year-round (Eddleman et al. 1994). The tidal marsh habitat on the Project site consists of thin strips along the edges of the site, dominated in some areas by pickleweed and in others by tall cattails and rushes. These marshes are limited in extent, provide open to moderate cover rather than dense cover, offer a narrow tidal zone, and are highly disturbed by adjacent human activities. This habitat is of marginal quality, at best, for nonbreeding black rails, and not sufficiently extensive for use by breeding Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201042 rails. Further, the species is not currently known to breed in the South Bay. Therefore, we do not expect black rails to occur on the Project site. California clapper rail (Rallus longirostrus obsoletus). Federal Listing Status: Endangered; State Listing Status: Endangered and Fully Protected. The California clapper rail was listed as endangered by the U.S. Fish and Wildlife Service in 1970 (USFWS 1970) and is designated as both endangered and fully protected in the state of California (Baron and Takekawa 1994). Critical Habitat has not been designated for this species. The California clapper rail is a year-round endemic to the tidal marshes fringing the San Francisco Bay (Schwartzbach et al. 2006), although historically populations also occurred in salt marshes in the Tomales, Monterey, and Morro Bays (Harvey 1990, Eddleman and Conway 1998). Rail populations were decimated by extensive habitat loss and hunting in the 19th and early 20th centuries (Baron and Takekawa 1994). Continued degradation and loss of tidal marsh habitat, pollution, and the ubiquitous presence of non-native predators such as red fox (Vulpes vulpes) and feral cats (Felis catus) continue to limit rail populations throughout their remaining distribution (Foin et al. 1997, Schwartzbach et al. 2006). Rails are obligate salt-marsh inhabitants, particularly where pickleweed (Salicornia spp.) and/or non-native cordgrass (Spartina spp.) are the dominant vegetation. They construct cup nests in the upper marshes near tidal sloughs beginning in late March; the breeding season runs through August. They forage in the mud of tidal sloughs, retreating to the upper marsh during high tides. Prime habitat for California clapper rails consists of broad patches of pickleweed-dominated salt marsh free from introduced predators, with abundant slough channels, a fringe of tall salt marsh vegetation above the high-tide line, and abundant invertebrate populations (Eddleman and Conway 1998). California clapper rails are documented occurring throughout portions of San Francisco Bay in relatively extensive channeled tidal marshes dominated by pickleweed. The nearest recently documented breeding population is a small group of birds that persist in a tidal marsh just north of the San Francisco Airport, approximately 1.5 mi south of the Project site (CNDDB 2010). Locations of other nearby populations include southern Alameda Island approximately 10 mi east of the Project site, the Emeryville Crescent Marsh approximately 12 mi northeast of the Project site, and Seal Slough approximately 7.5 mi south of the Project site (CNDDB 2010). The tidal marsh habitat on the Project site consists of thin strips along the edges of the site, dominated in some areas by pickleweed and in others by tall cattails and rushes. These marshes are limited in extent, provide open to moderate cover, offer only one narrow channel, and are highly disturbed by adjacent human activities. They therefore do not provide suitable breeding habitat for clapper rails. It is possible that an occasional dispersant could use marsh vegetation on the site, but such individuals are expected to occur very infrequently and for brief duration, if at all. California least tern (Sterna antillarum browni). Federal Listing Status: Endangered; State Listing Status: Endangered and Protected. The California least tern was listed as endangered by the U. S. Fish and Wildlife Service in 1970 (USFWS 1970), and is designated as both endangered and fully protected in the state of California. No critical habitat has been designated for this species. California least terns historically nested widely along the Pacific Coast from the San Francisco Bay area to Baja California, but pervasive habitat loss, along with increasing predation pressures and disturbance due to recreational activities, has radically constrained the range and abundance of this species. Habitat degradation is ongoing, and nest predation by feral cats and other human-associated species such as raccoons and crows now poses a grave threat Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201043 (Atwood et al. 1994, Akçakaya et al. 2003). Currently, California least terns are found only in one breeding colony in the San Francisco Bay area, and breed sparsely at a few coastal sites from San Luis Obispo County to San Diego County (Atwood et al. 1994). California least terns inhabit broad, sparsely vegetated sandy beaches or mudflats near the coast, where they can construct shallow scrape nests in sand or gravel (Thompson et al. 1997). Ideal nesting habitat for California least terns is typified by open, undisturbed beaches with little to no vegetation or debris and an absence of nest predators. Least terns exhibit high site fidelity despite the typically ephemeral nature of their preferred breeding habitat (Thompson et al. 1997, Akçakaya et al. 2003). Nesting colonies averaging 30-50 pairs begin to establish themselves in late April, and breeding continues through early September, after which the birds migrate to wintering grounds in southern Mexico (Thompson et al. 1997). California least terns occur in the San Francisco Bay, and have established a nesting population near the Alameda Naval Air Station approximately 9 mi northeast of the Project site. The Project site does offer a strip of sandy beach habitat, but it is very small, highly disturbed, and frequented by predators such as feral cats and American crows. Therefore, suitable nesting habitat for California least terns is absent from the Project site. It is possible that birds from the Alameda colony, or possibly from a colony in Suisun Bay, could forage in the Bay adjacent to the Project site, though such individuals are expected to occur irregularly and/or in small numbers. Western snowy plover (Charadrius alexandrinus nivosus). Federal Listing Status: Threatened; State Listing Status: Species of Special Concern. Coastal populations of western snowy plover were listed as threatened by the USFWS in 1993 (USFWS 1993), and critical habitat was designated in 1999 (USFWS 1999). The western snowy plover is a small shorebird distributed along the pacific and gulf coasts of the United States, and patchily in the interior west during the winter months (Page et al. 1995). Snowy Plover breeding habitat on the pacific coast is typified by sandy beaches, gravel spits, salt pans, and other open, sparsely vegetated habitats near the ocean (Colwell et al. 2005). Breeding begins in California around mid-February, and nesting birds lay one to three clutches of 2 to 6 eggs in shallow scrapes near patches of cover such as driftwood, kelp, or low vegetation. The breeding season runs through September, and in central California plover populations persist throughout the year, with non- breeding birds foraging on invertebrates on shorelines, tidal flats, and salt ponds (Page et al. 1995). Optimal snowy plover nesting habitat is comprised of sandy substrates with sparsely distributed camouflaging debris or shrubs, supporting only low numbers of native predators and no introduced predators, and protected from human activities including off-road vehicles. The majority of coastal snowy plover habitat is threatened by habitat loss and degradation, disturbance due to human activities, and an influx of introduced nest predators (Ruhlen et al. 2003, Neuman et al. 2004). Although snowy plovers nest primarily on sandy beaches along the coast, breeders inside San Francisco Bay nest primarily in extensive salt pannes. Salt panne habitat is absent from the Project site, and the small patch of sandy beach on the Project site is too small, highly disturbed, and frequented by predators such as feral cats and American crows to provide suitable breeding habitat, or even foraging habitat for this species. Therefore, the snowy plover is not expected to occur on the Project site. Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201044 Salt marsh harvest mouse (Reithrodontomys raviventris). Federal Listing Status: Endangered; State Listing Status: Endangered. The salt marsh harvest mouse was listed as endangered by the U.S. Fish and Wildlife Service in 1970 (USFWS 1970) and by the California Fish and Game in 1971. Critical habitat has not been designated for this species. The salt marsh harvest mouse is restricted to the San Francisco bay area and its tributaries. It is a salt marsh obligate and requires both dense patches of pickleweed (Salicornia virginica) and high ground refuge locations during high tide (Shellhammer 1982, Shellhammer et al. 1982). Salt marsh harvest mice subsist mainly on leaves, seeds, plant stems and green grasses (Bias 1994, Shellhammer 1982). The listing of the salt marsh harvest mouse was a direct result of habitat loss, which has declined by 80% (Shellhammer 1982) from its original size of 183 mi2. Breeding of the salt marsh harvest mouse takes place primarily between August and November (Bias 1994, Bias and Morrison 2006). Average home range is approximately 0.53 ac for both sexes. Continued threats to the salt marsh harvest mouse are further habitat fragmentation and degradation (e.g., pollution, invasion by non-native predators). Salt marsh harvest mice have not been recorded on the San Francisco peninsula north of Foster City in decades. The pickleweed marshes on the Project site are poorly developed and highly disturbed, offering marginal habitat at best for the species. The nearest extant populations are distant and separated from the Project area by substantial habitat alteration. Therefore, we do not expect salt marsh harvest mice to occur on the Project site. California Species of Special Concern or State Fully Protected Species White-tailed kite (Elanus leucurus). Federal Listing Status: None; State Listing Status: Fully Protected. The white-tailed kite ranges throughout the western states and Florida where suitable habitat occurs.In California, white-tailed kites can be found in the Central Valley and along the coast, in grasslands, agricultural fields, cismontane woodlands, and other open habitats (Polite et al. 1990, Dunk 1995, Erichsen et al. 1996). Although the species rallied impressively after marked reductions during the early 20th century, populations may be exhibiting new declines as a result of recent increases in habitat conversion and disturbance (Erichsen et al. 1996). White-tailed kites are year-round residents of the state, establishing breeding territories that encompass open areas with healthy prey populations, and snags, shrubs, trees, or other nesting substrates (Dunk 1995).Non-breeding birds typically remain in the same area over the winter, although some movements do occur (Polite et al. 1990). The presence of white-tailed kites is closely tied to the presence of prey species, particularly voles, and prey base may be the most important factor in determining habitat quality for white-tailed kites (Dunk and Cooper 1994, Skonieczny and Dunk 1997). White-tailed kites have been observed in the general Project vicinity during the breeding season (CNDDB 2010, eBird 2010). The annual grassland and even some landscaped habitats on the Project site offer suitable foraging habitat. Although the pines and Eucalyptus trees comprising the ornamental forest offer potential nesting habitat, there is a low probability that a pair of kites would establish a nest in such a highly disturbed area with such limited foraging habitat. Therefore, if the species occurs on the Project site, it is likely to occur only as an occasional nonbreeding visitor. Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201045 Burrowing owl (Athene cunicularia). Federal Listing Status:None; State Listing Status: Species of Special Concern (breeding). Western burrowing owls can be found in grassland habitats throughout western and Midwestern North America (Haug et al. 1993). In California burrowing owls are distributed throughout the state, with populations in the northeast; in the Central Valley, interior San Francisco Bay Area, and Salinas Valley; on the Carrizo Plain and in the Imperial Valley; and on several of the Channel Islands. Habitat loss has reduced the abundance of this species within its range and resulted in local extirpations, particularly along the central and southern coasts (Gervais et al. 2008). California hosts both migratory and sedentary populations of burrowing owls (Rosenberg et al. 2007). These owls favor flat, open grassland or gentle slopes and sparse shrubland ecosystems for breeding, through they will also readily colonize agricultural fields and other developed areas (Haug et al. 1993, Conway et al. 2006). Mammal burrows, or other structures that mimic burrows, provide secure nesting locations and non- breeding refuges and are a fundamental ecological requirement of burrowing owls (Gervais et al. 2008); in California, owls are most often found in close association with California ground squirrel burrows (Rosenberg et al. 2007). Ideal habitat for burrowing owls is comprised of annual and perennial grasslands with low vegetation height, sparse or nonexistent tree or shrub cover, and an abundance of mammal burrows (Coulombe 1971, Haug and Oliphant 1990, Plumpton and Lutz 199). The nesting season as recognized by the California Department of Fish and Game (1995) runs from February 1 through August 31. After nesting is completed, adult owls may remain in their nesting burrows or in nearby burrows, or may migrate; young birds disperse across the landscape, from 0.12 mi to 33 mi from their natal burrows (Rosier et al. 2006). Burrowing owls occur at scattered locations throughout the South San Francisco Bay Area where low grasslands and ruderal habitats support ground squirrel colonies. Although the Project site features several patches of annual grassland and ruderal habitat, such habitat is very limited in extent, and no ground squirrel burrows were in evidence during the reconnaissance survey in November 2009. Nonbreeding burrowing owls could potentially occur on the Project site (e.g., during migration and winter), possibly roosting in riprap, but due to the limited nature of suitable foraging habitat and absence of high-quality burrows, such individuals are expected to occur irregularly and in small numbers, if at all. Loggerhead shrike (Lanius ludovicianus). Federal Listing Status:None; State Listing Status: Species of Special Concern (nesting). The loggerhead shrike is distributed throughout much of California, except in higher-elevation and heavily forested areas including the Coast Ranges, the Sierra Nevada, the southern Cascades, the Klamath and Siskiyou ranges, and the highest parts of the Transverse Ranges (Humple 2008). While the species range in California has remained stable over time, populations have declined steadily (Cade and Woods 1997). Loggerhead shrikes establish breeding territories in open habitats with relatively short vegetation that allows for visibility of prey; they can be found in grasslands, scrub habitats, riparian areas, other open woodlands, ruderal habitats, and developed areas including golf courses and agricultural fields (Yosef 1996). They require the presence of structures for impaling their prey; these most often take the form of thorny or sharp- stemmed shrubs, or barbed wire (Humple 2008). Ideal breeding habitat for loggerhead shrikes is comprised of short grass habitat with many perches, shrubs or trees for nesting, and sharp branches or barbed wire fences for impaling prey. Shrikes nest earlier than most other passerines, especially in the Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201046 west where populations are sedentary. The breeding season may begin as early as late February, and lasts through July (Yosef 1996).Nests are typically established in shrubs and low trees including sagebrush, willow, and mesquite, through brush piles may also be used when shrubs are not available. Loss and degradation of breeding habitat, as well as possible negative impacts of pesticides, are considered to be the major contributors to the population declines exhibited by this species (Cade and Woods 1997). Loggerhead shrikes are uncommon in the Bay Area but have been recorded occasionally in the Project vicinity (eBird 2010), and have been documented breeding on east San Bruno Mountain (Sequoia Audubon Society 2001). The Project site offers potential foraging and nesting habitat, particularly in the southeastern corner where Phase I of the Project is planned. However, there is a low probability that a pair would establish a nest in such a highly disturbed area with such limited foraging habitat. Therefore, if the species occurs on the Project site, it is likely to occur only as an occasional nonbreeding visitor. San Francisco common yellowthroat (Geothlypis trichas sinuosa). Federal Listing Status: None State Listing Status: Species of Special Concern (breeding). The San Francisco (also known as Salt Marsh) subspecies of the widely-distributed common yellowthroat is found only on the immediate coast of California from Tomales Bay in the north to the southern edge of San Mateo County in the south, including the San Francisco Bay. Their current range reflects their historic distribution, but habitat degradation and loss dramatically reduced the abundance of the subspecies within its range, even resulting in local extirpations before increases in freshwater marsh habitats on the bay began increasing in the 1980s as a result of increases in freshwater effluent discharged from wastewater treatment plants (Gardali and Evens 2008). San Francisco common yellowthroats are typically associated with brackish marshes and freshwater riparian swamps; they nest in the dense emergent vegetation that grows up in such moist areas (Guzy and Ritchison 1999).Common yellowthroats will use small and isolated patches of habitat as long as groundwater is close enough to the surface to encourage the establishment of dense stands of rushes (Scirpus spp.), cattails, willows (Salix spp.), Juncus spp., or other emergent vegetation (Nur et al. 1997). Ideal habitat, however, is comprised of at least 0.4 ha of thick riparian or marsh vegetation in perpetually moist areas, where populations of brown-headed cowbirds (Molothrus ater) are low (Menges 1998). Common yellowthroats build open- cup nests low in the vegetation, and nest from mid-march through late July. Common yellowthroats remain in their breeding range year-round (Guzy and Ritchison 1999, Gardali and Evens 2008). Common yellowthroats have been observed in the Project area during the breeding season (eBird 2010), and the site possesses small amounts of potential breeding habitat for the species. A few pairs could have breeding territories on the Project site, most likely along the tidal channel on the southern edge of the site. Alameda song sparrow (Melospiza melodia pusillula). Federal Listing Status: None; State Listing Status: Species of Special Concern. The Alameda song sparrow is a subspecies of the widely distributed song sparrow, which can be found, typically near water, in nearly every habitat type throughout North America (Arcese et al. 2002).The Alameda song sparrow is a year-round endemic resident of the salt marshes of the San Francisco Bay from the cities of San Francisco and El Cerrito at the northern end of its range, to the southern limits of the Bay in Santa Clara County (Chan and Spautz 2008). While the range of the Alameda song sparrow has Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201047 remained relatively unchanged over time, populations have been reduced substantially and are continually threatened by the loss and fragmentation of salt marshes around the Bay (Nur et al. 1997, Chan and Spautz 2008). Alameda song sparrows are inhabitants of tidally-influenced salt marshes dominated by pickleweed (Salicornia sp.) and cordgrass (Spartina sp.) (Chan and Spautz 2008). They breed from February through August, and require some areas of high marsh for nesting habitat, in order to avoid inundation of nests during high tides (Arcese et al. 2002). While Alameda song sparrows will nest in exotic cordgrass as well as native pickleweed, birds nesting in cordgrass experience a significantly lower rate of nest success, largely due to tidal flooding, than birds nesting in native pickleweed, which is typically found at higher elevations in the marsh and is thus less susceptible to flooding (Nordby et al. 2008). Alameda song sparrows forage on bare ground along sloughs and in bare patches within the tidal marshes, consuming plants and invertebrates. Prime habitat for Alameda song sparrows is composed of large areas of tidally-influenced marsh intersected by tidal sloughs, offering dense vegetative cover, singing perches, and areas of high marsh for nesting; free from cordgrass and introduced predators; and adjacent to extensive upland habitat (Chan and Spautz 2008). Alameda song sparrows have been documented historically in the Project vicinity in Belmont, San Bruno, San Mateo, and near Colma Creek (CNDDB 2010). Song sparrows of undetermined subspecies were observed in the Project area during the November 2009 reconnaissance survey, and have been observed near the Project area at Colma Creek during the breeding season (eBird 2010). The small amounts of tidal marsh within the Project area serve as potential breeding habitat for Alameda song sparrows. If this subspecies breeds on or near the Project site, it is most likely to breed along the tidal channel on the southern edge of the site or in the marsh adjacent to the site near the Oyster Cove Marina. Bryant’s savannah sparrow (Passerculus sandwichensis alaudinus). Federal Listing Status: None; State Listing Status: Species of Special Concern. Bryant’s savannah sparrow, a subspecies of the widely distributed savannah sparrow, is a California endemic ranging along the immediate coast from Humboldt Bay, Humboldt County, in the north; to Point Conception, Santa Barbara County, in the south (Wheelwright and Rising 2008). Bryant’s savannah sparrows breed from April through July (Dobkin and Granholm 1990) in the upper portions of tidally-influenced marshes, grasslands and ruderal habitats adjacent to tidal marshes, moist grasslands and pastures within the fog belt, and occasionally in drier grasslands up to 25 mi inland. Ideal habitat is comprised of extensive moist grassland or upper marsh habitats with relatively short vegetation, some patches of bare ground, and nearby drainages (Fitton 2008). Cup nests are built on or near the ground in dense vegetation (Wheelwright and Rising 2008). Non-breeding habitat preferences are little known, but may be similar to breeding season habitats. The range of the Bryant’s savannah sparrow has remained relatively stable, but numbers have declined, largely due to habitat loss, fragmentation, and degradation (Fitton 2008). Savannah sparrows have been regularly observed in the Project vicinity, but most of these individuals were observed during migration and winter periods. A few individuals have been documented during the breeding season about 3.5 mi north of the Project site at Bayview Hill, and approximately 8 mi south of the Project site at Tidelands Park in Foster City (eBird 2010). Breeding savannah sparrows have been documented on western San Bruno Mountain, in San Bruno, and in Millbrae (Sequoia Audubon Society 2001). The salt marsh habitat adjacent to the Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201048 Project site is of marginal quality for this species due to its small size and proximity to human disturbance, but up to a few pairs could potentially breed along the tidal channel on the southern edge of the site or in the marsh adjacent to the site near the Oyster Cove Marina. Sensitive and Regulated Plant Communities and Habitats The CDFG ranks certain rare or threatened plant communities, such as wetlands, meadows, and riparian forest and scrub, as ‘threatened’ or ‘very threatened’. These communities are tracked in the CNDDB. Impacts to CDFG sensitive plant communities, or any such community identified in local or regional plans, policies, and regulations, must be considered and evaluated under the California Environmental Quality Act (California Code of Regulations: Title 14, Div. 6, Chap. 3, Appendix G). Furthermore, wetland and riparian habitats are also afforded protection under applicable federal, state, or local regulations, and are generally subject to regulation, protection, or consideration by the U.S. Army Corps of Engineers (USACE), Regional Water Quality Control Board (RWQCB), CDFG, and/or the USFWS. Essential Fish Habitat is identified and regulated by the National Marine Fisheries Service (NMFS) in collaboration with regional, state and local agencies, and is defined as any habitat that is essential to the long-term survival and health of United States fisheries. Eelgrass beds are considered a sensitive resource by the USACE and CDFG because little accurate information exists about the historic distribution of eelgrass beds, and because of their current relative scarcity and importance in the overall ecology of the bay. CDFG Sensitive Habitats. No sensitive habitats are mapped by the CDFG in the Project vicinity (Figure 3). Essential Fish Habitat. The tidal aquatic habitats on and adjacent to the Project site are considered EFH by the NMFS for a species assemblage that includes anchovies, sardines, rockfish, sharks, sole, and flounder. Areas supporting the native Olympia oyster, such as the hardened shoreline and the marina breakwater, are also considered EFH by NMFS because oyster beds serve a number of important roles in the Bay ecosystem. Eelgrass Beds. Eelgrass beds form areas of important habitat for birds, fish, and crustaceans and are one of the preferred spawning habitats of pacific herring (Wyllie-Echeverria and Fonseca 2003). These plants also support grazing crustaceans, shrimp, and amphipods. Because it requires light for photosynthesis, eelgrass is limited by water clarity to depths of about 6 feet or less. Eelgrass beds and patches occur in both subtidal and intertidal areas of the San Francisco Bay. Although no eelgrass beds or patches have been mapped closer than 3 mi from the Project area, the NMFS (2010) considers portions of Oyster Point to offer suitable eelgrass habitat, and there is some evidence that eelgrass populations in the Bay are expanding (Merkel & Associates 2004). Thus, we cannot rule out the possibility that eelgrass patches or beds have become established in or near the Project area. Waters of the U.S./State. As discussed under Regulatory Setting above, open water and intertidal habitats of San Francisco Bay, the tidal canal at the southern edge of the site, and associated wetlands and shoreline areas (extending up to the high tide line or the upper limits of wetlands, whichever is higher) are considered Waters of the U.S. under the Clean Water Act and Waters of the State under the Porter-Cologne Water Quality Control Act. The approximate Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201049 upslope limits of such areas are shown on Figure 2. These wetlands and aquatic habitats are also important habitats for a variety of animal species. Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201050 IMPACTS AND MITIGATION MEASURES The proposed Project may have effects on the biological resources of the Project site. The California Environmental Quality Act (CEQA) and the CEQA Guidelines provide guidance in evaluating project impacts and determining which impacts will be significant. CEQA defines “significant effect on the environment” as “a substantial adverse change in the physical conditions which exist in the area affected by the proposed project.” Under CEQA Guidelines section 15065 and Appendix G, a project’s effects on biotic resources may be significant when the project would: x “have the potential to degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self- sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory” x “have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Service” x “have a substantial adverse effect on any riparian habitat or other sensitive natural community (e.g., oak woodland) identified in local or regional plans, policies, regulations or by the California Department of Fish and Game or U.S. Fish and Wildlife Service” x “have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act” x “interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites” x “conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance” x “conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan” The following impact analyses consider the Project-specific impacts of proposed Phase I activities and the programmatic impacts of other activities that could be performed as part of the Project. PROJECT-SPECIFIC ANALYSIS: MASTER PLAN PHASE I Key Assumptions The following impact analysis is based on several key assumptions: Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201051 x No grading or placement of fill, either temporary or permanent, will occur in any aquatic or wetland habitat (i.e., within the “Approximate Limit of USACE Jurisdiction” indicated on Figure 2) during Phase I activities. x The tallest building to be constructed in Phase I is 10 stories high. x Lighting will be in conformance with the Master Plan’s lighting guidelines. IMPACTS FOUND TO BE LESS THAN SIGNIFICANT Impacts to Developed/Landscaped, California Annual Grassland/Coyote Brush Scrub, and Ornamental Woodland Habitats Phase I construction may result in the loss or conversion of up to 20.05 ac of developed/landscaped, 14.20 ac of California annual grassland/coyote brush scrub, and 0.57 ac of ornamental woodland habitat due to the construction of buildings, landscaping, and other activities. These habitats are located within the boundary of Phase I of the Project, and above USACE jurisdiction. An additional 0.72 acres of northern coastal salt marsh, 0.01 acres of armored rock levee slope, and 0.11 acres of sandy beach habitat are located within the boundary of Phase I of the Project and within USACE jurisdiction; however, these areas will be avoided during construction. Impacts to habitats during Phase I of construction will reduce the extent of these habitat types on the Project site, and will result in a reduction in abundance of some of the common wildlife species that use the site. However, these habitat types are relatively abundant and widespread regionally, and none of the habitats to be impacted by Phase I activities represent particularly sensitive, valuable (from the perspective of providing important wildlife habitat), or exemplary occurrences of these habitat types. Therefore, impacts to these habitats, and the loss of potential nesting, roosting, and foraging opportunities associated with such habitats, are not considered significant. Impacts to Trees Protected by the City’s Tree Protection Ordinance One or more mature blue gum trees within the ornamental woodland habitat may satisfy size requirements for a “protected tree” under the City of South San Francisco’s Tree Protection Ordinance. Trees are considered protected if they are 48 inches or more at 54 inches above the natural grade. These trees, while providing some wildlife habitat, are non-native invasive trees that severely degrade natural habitats. Eucalyptus species outcompete native species and produce leaf litter that reduces the diversity and cover, and can alter fire regimes within the associated woodland understory. If any of these trees are found to be of sufficient size to be considered protected under the City’s ordinance, a permit will be required for their removal. However, due to the low habitat functions and values provided by these trees, their loss, and the loss of potential nesting, roosting, and foraging opportunities associated with them, is not considered significant. Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201052 Impacts to Habitat for and Individuals of Non-breeding Special-Status Wildlife Species Several terrestrial special-status species may use the Project area as transients or migrants, or may occur in very low numbers, but are not expected to breed at the site or to be present in any numbers, and thus would not be impacted significantly by Project activities. These species include the American peregrine falcon, black skimmer, harlequin duck, northern harrier, Vaux’s swift, yellow warbler, and tricolored blackbird. American peregrine falcons have been observed occasionally on the Project site and throughout the Project vicinity; the nearest confirmed breeding location is on Bair Island near Redwood City (Sequoia Audubon Society 2001). This species is uncommon throughout the Bay Area, and does not occur frequently or in large numbers in the Project area. Black skimmers and California least terns are known to occur in the Bay in low numbers throughout the year, and a small breeding population of each species has become established in the South Bay. However there is no suitable nesting habitat for these species on the Project site and individuals are expected to forage in the small amount of marine aquatic habitat within the Project area rarely if at all. Harlequin ducks occur regularly in low numbers in the Project vicinity during the non-breeding season only. The Project site is outside of the known breeding range of the species (Robertson and Goudie 1999), and individuals are expected to occur in the Project area rarely if at all. Northern harriers breed in San Mateo County (Sequoia Audubon Society 2001) and are regularly observed in grassy and marshy habitats throughout the year. Occasional individuals may forage in the grassy habitats on the Project site, but harriers are not expected to occur frequently or in any numbers, or to nest on the site. Vaux’s swifts may occasionally forage for insects over the Project area, but would not roost there, nor would they occur frequently or in large numbers. Yellow warblers have been observed in the Project vicinity during migration, and the species forages in the Project area during migratory periods. However, the species is not expected to nest on the Project site. Tricolored blackbirds may occasionally forage in open grassy or ruderal portions of Project area, but records of birds in the vicinity are few, and they are not expected to occur there in any numbers or to nest on the site. Project construction would not result in injury or mortality of any individuals of these species, which are mobile enough to avoid construction equipment. There would be no substantial loss of foraging or non-breeding habitat for any of these species, as the Project footprint primarily includes already developed and/or heavily impacted areas. As a result, the Project’s impacts do not meet the CEQA standard of having a substantial adverse effect on these species’ populations, and the Project will have a less than significant impact on these species. Impacts to Habitat for and Individuals of Certain Potentially Nesting Special-Status Birds Some special-status bird species could potentially nest in or adjacent to the Project area but are not expected to be significantly impacted by the Project. These species include the white-tailed kite and loggerhead shrike, for which there is a very low probability of nesting, as well as the San Francisco common yellowthroat, Alameda song sparrow, and Bryant’s savannah sparrow, which have a somewhat higher probability of nesting in wetland vegetation at the periphery of the site. Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201053 White-tailed kites and loggerhead shrikes are uncommon to rare on the Peninsula due to the scarcity of suitable grassland habitat, and due to the limited extent of foraging habitat and disturbance, there is a low probability that either species nests on the site. Nevertheless, there is some potential for up to one pair of each species to nest in the southwestern portion of Phase I of the Project area. Any such nesting pairs would be displaced by Project activities. Therefore, a small amount of marginal nesting and foraging habitat will be removed as a result of Project activities. San Francisco common yellowthroats occur throughout the Bay Area in tidal marshes and nearby freshwater riparian areas. Common yellowthroats have been observed in the Project area, and enough suitable nesting habitat exists on the Project site that up to two pairs of common yellowthroats could establish nesting territories in wetland vegetation along the tidal channel south of the Project site or just outside the northwestern part of the Project site. Project activities will not result in the loss of any nesting or foraging habitat, but breeding individuals could be disturbed or displaced by construction-related noise and activity. Alameda song sparrows are restricted to salt marsh habitat, which will not be impacted by Phase I the proposed Project. Bryant’s savannah sparrows utilize salt marsh habitat as well, but can also be found in adjacent ruderal or grassland habitats, which will be lost as a result of Project activities. Pairs of song sparrows or savannah sparrows nesting in the salt marsh habitat within the Project area could be disturbed by noise, movement, and other construction activities. Any pairs of savannah sparrows nesting in the ruderal or grassland areas within the Phase I footprint would be displaced by Project activities. However, the amount of salt marsh habitat in the Project area is small and the quality is low, and thus the number of pairs of these species that could potentially be disturbed due to Project activities represents a very small fraction of the regional population. Likewise, the number of savannah sparrows that could potentially nest in the small patch of ruderal grassland habitat within the Phase I footprint is low. Because the amount and quality of habitat for white-tailed kites, loggerhead shrikes, San Francisco common yellowthroats, Alameda song sparrows, and Bryant’s savannah sparrows being impacted is low, and the number of nesting individuals that could be disturbed is very small, the Project’s impacts would not substantially reduce regional populations of these species, and thus these impacts do not meet the CEQA standard of having a substantial adverse effect on these species. Although the loss of any active nests of protected birds would be in violation of federal and state laws (see Regulatory Setting above), impacts to these species and their habitats would not be considered a significant impact under the CEQA. Impacts of Lighting on Terrestrial and Aquatic Animals Lighting in and adjacent to more natural areas on the Project site, especially the shoreline along San Francisco Bay, is expected to increase as a result of the Project. Artificial lighting has been demonstrated to cause changes in the physiology and behavior of a number of animal taxa; while some animals take advantage of artificial lighting to more easily detect prey at night, or take advantage of prey concentrations attracted to artificial lights, other animals are adversely affected by artificial lighting (Rich and Longcore 2006). Species such as birds and amphibians can become disoriented by changes in lighting, and many species of insects are attracted to light (Longcore and Rich 2004). Reproductive behaviors of some species can be affected by the Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201054 increased risk of predation caused by increases in lighting, and visual communication between individuals of can be disrupted by lighting (Longcore and Rich 2004). In more remote areas that are not already subjected to urban lighting, an increase in night lighting could disrupt the behavior of animals, potentially increase predation on some nocturnal animals, and result in displacement of the most sensitive species from areas with increased lighting. However, the Project area is already subjected to substantial amounts of night lighting, including night lighting from roads, parking lots, and buildings. As a result, any wildlife currently using the site is habituated to the lighting present within this urban area. The Project incorporates guidelines for the design of lighting to minimize light pollution in areas other than those intended to be lit. For example, lighting will be directed downward at low cut- off angles to minimize off-site light migration and the Project’s contribution to light pollution. Because there is already a substantial amount of artificial lighting at Oyster Point, the implementation of these guidelines will prevent the installation of new lighting from substantially increasing lighting levels, and from impacting terrestrial and aquatic species. Therefore, impacts from increased lighting levels on wildlife will be less than significant. Impacts of Increased Recreational Disturbance on Wildlife Recreational demand in the Oyster Point area is expected to increase with the development of the Project, resulting from the associated increase in the population of people working at and using the oyster point site. Increases in the use of Oyster Point could potentially subject biological resources (both within and outside the oyster point site, such as waterbirds using the edge of San Francisco Bay) to greater disturbance by people walking and biking. However, because there is already a substantial amount of human activity at Oyster Point, wildlife that is present at Oyster Point and in surrounding areas is already largely habituated to high levels of human activity. Increased use of trails or other areas that are already fairly heavily used by people is thus not expected to reduce the use of such areas by wildlife. Therefore, an increase in recreational users of the Bay Trail and other areas adjacent to wildlife habitat resulting from construction of the Project is not expected to have a substantial effect on wildlife in these areas. IMPACTS FOUND TO BE LESS THAN SIGNIFICANT WITH MITIGATION Indirect Impacts to Water Quality and Sensitive Habitats Although no Phase I activities will occur in wetland or aquatic habitats, some grading, construction, and landscaping will occur in close proximity to, and upslope from, such sensitive habitats. There is thus some potential for Phase I activities to result in indirect effects on these habitats and on water quality in adjacent aquatic habitats. For example, in the absence of measures to prevent erosion and sedimentation, sediment may wash from construction areas into adjacent aquatic habitats, or soil loosened by grading could slide downslope into such areas. Such impacts could result in the loss or degradation of wetland or aquatic habitats, and degradation of water quality in adjacent waters. Also, Phase I activities include the installation of stormwater outfalls from the buildings to be constructed in the southwestern part of the site. These features will outfall into vegetated swales that are to be constructed just upslope from the wetlands and tidal channel that form the southwestern boundary of the site. If these swales are Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201055 not adequately constructed, there is some potential for excessive erosion or the release of untreated runoff into these wetlands and tidal waters. Due to the value of wetland habitats to the ecology of the Bay’s aquatic habitats and the value of these aquatic habitats to a variety of fish, benthic organisms, and other species, degradation of water quality or wetlands would be a significant impact. The following mitigation measures will reduce construction-phase impacts on water quality to a less-than-significant level. Mitigation Measure 1A. Incorporate Best Management Practices for Water Quality During Construction. The Project will incorporate Best Management Practices (BMPs) for water quality to minimize impacts in the surrounding wetland environment, sloughs and channels, and the San Francisco Bay during construction. These BMPs will include numerous practices that will be outlined within the Stormwater Pollution Prevention Plan (SWPPP), but will include measures such as: 1.No equipment will be operated in live flow in any of the sloughs or channels or ditches on or adjacent to the site. 2.No debris, soil, silt, sand, bark, slash, sawdust, cement, concrete, washings, petroleum products or other organic or earthen material shall be allowed to enter into or be placed where it may be washed by rainfall or runoff into aquatic or wetland habitat. 3.Standard erosion control and slope stabilization measures will be required for work performed in any area where erosion could lead to sedimentation of a waterbody. For example, silt fencing will be installed just outside the limits of grading and construction in any areas where such activities will occur upslope from, and within 50 ft of, any wetland, aquatic, or marsh habitat. This silt fencing will be inspected and maintained regularly throughout the duration of construction. 4.Machinery will be refueled at least 50 ft from any aquatic habitat, and a spill prevention and response plan will be developed. All workers will be informed of the importance of preventing spills and of the appropriate measures to take should a spill occur. Mitigation Measure 1B. Minimize Soil Disturbance Adjacent to Wetland and Marsh Habitat. To the extent feasible, soil stockpiling, equipment staging, construction access roads, and other intensively soil-disturbing activities will not occur immediately adjacent to any wetlands that are to be avoided by the Project. The limits of the construction area will be clearly demarcated with Environmentally Sensitive Area fencing to avoid inadvertent disturbance outside the fence during construction activities. Mitigation Measure 1C. Ensure Adequate Stormwater Run-off Capacity. Increases in stormwater run-off due to increased hardscape will be mitigated through the construction and maintenance of features designed to handle the expected increases in flows and provide adequate energy dissipation. All such features, including outfalls, will be regularly maintained to ensure continued function and prevent failure following construction. Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201056 Impacts to Individual Burrowing Owls Although no burrowing owls or ground squirrel burrows were observed on the Project site during the November 2009 or September 2010 reconnaissance surveys, burrowing owls could potentially occur on the Phase I site in grassland habitats if ground squirrels are present. There is also some potential for occasional transient owls to use crevices in shoreline riprap as temporary refugia. In the unlikely event that owls were nesting on the site, construction-related disturbance during the breeding season could result in the incidental loss of fertile eggs or nestlings, or otherwise lead to nest abandonment. However, if burrowing owls occur on the site at all, they likely do so as nonbreeding visitors. Because this species live in burrows even during the non- breeding season, they are more likely to take refuge in those burrows rather than flushing in response to disturbance as most birds do, therefore raising the risk of individual owls being crushed in their burrows during construction activities in any season. Due to the marginal nature of habitat on the site, and the current lack of suitable breeding sites in the form of ground squirrel burrows, the Project will not result in a significant loss of burrowing owl habitat. Nevertheless, any loss of burrowing owls or fertile eggs, any activities resulting in nest abandonment, or the destruction of occupied burrowing owl burrows would constitute a significant impact under CEQA due to the regional rarity of the species and declining nature of its populations. The following mitigation measures would reduce impacts to a less-than- significant level. Mitigation Measure 2A. Pre-construction Surveys.Pre-construction surveys for burrowing owls shall be completed in potential habitat in conformance with the California Burrowing Owl Consortium protocol, no more than 30 days prior to the start of construction. If no burrowing owls are located during these surveys, no additional action would be warranted. However, if burrowing owls are located on or immediately adjacent to the site the following mitigation measures will be implemented. Mitigation Measure 2B. Buffer Zones.For burrowing owls present during the non-breeding season (generally 1 September to 31 January), a 150-ft buffer zone will be maintained around the occupied burrow(s) if practicable. If such a buffer is not practicable, then a buffer adequate to avoid injury or mortality of owls will be maintained, or the birds will be evicted as described for Mitigation Measures 2C, below. During the breeding season (generally 1 February to 31 August), a 250-ft buffer, within which no new activity will be permissible, will be maintained between Project activities and occupied burrows. Owls present on site after 1 February will be assumed to be nesting unless evidence indicates otherwise. This protected buffer area will remain in effect until 31 August, or based upon monitoring evidence, until the young owls are foraging independently or the nest is no longer active. Mitigation Measure 2C. Passive Relocation.If construction will directly impact occupied burrows, eviction of owls should occur outside the nesting season to prevent injury or mortality of individual owls. No burrowing owls will be evicted from burrows during the nesting season (1 February through 31 August) unless evidence indicates that nesting is not actively occurring (e.g., because the owls have not yet begun nesting early in the season, or because young have already fledged late in the season). Relocation of owls during the non-breeding season will be performed by a qualified biologist using one-way doors, which should be installed in all burrows Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201057 within the impact area and left in place for at least two nights. These one-way doors will then be removed and the burrows backfilled immediately prior to the initiation of grading. Impacts to Migratory Birds from Buildings and Lighting The Study Area is located along the Pacific Flyway for migratory birds, and the juxtaposition of wetland, shoreline, and open water habitats used by birds results in large-scale movements of birds along the edge of San Francisco Bay, both during long-distance movements (such as migration) and during daily movements between roosting and foraging habitats. During spring and fall migratory periods in particular, birders have documented high densities of migrant songbirds using vegetated areas at the edges of San Francisco Bay, and the Oyster Point Project area has the potential to support high densities of birds at times during migration. There is thus potential for injury or mortality of birds due to collisions with artificial structures such as buildings as birds engage in such movements. Many birds migrate at night, when it is difficult for them to see structures in their paths. In addition, birds migrating at night are often attracted to sources of artificial light, particularly during periods of inclement weather. Exposure to night lighting can cause alteration of flight paths and can attract birds to the light source (Keyes 2005, Gauthreaux and Belser 2006). As a result, bright lights on buildings can result in bird collisions with the buildings. Even during the day, birds may collide with windows or with tall, glass-covered buildings. Large-scale collisions resulting in mortality of large numbers of birds have been documented in eastern and Midwestern North America (Avery 1979), but it is possible that such mortality could occur in the West as well. Within the Project area, there is some potential for birds to collide during daytime and nocturnal flights with structures such as windows of office buildings. Structures currently present along the southern portion of Oyster Point are one to three stories high, while several structures at the northern end of Oyster Point are five stories high. The existing structures at Oyster Point are relatively low, and the exteriors of these buildings have been designed with clear patterns that do not result in extensive areas of reflective surfaces. As a result, most migrating birds would be flying above these buildings, and birds would easily be able to see these buildings because they are not comprised of extensive areas that reflect, and that thus would appear to a bird to be similar to, the sky. Therefore, the risk of bird strikes under existing conditions is expected to be relatively low. The tallest new building that will be constructed during Phase I of the Project will be 10 stories, or 195 ft, with additional buildings at heights of 130 ft and 75 ft.Relative to the height of the existing structures, several of the Project’s proposed buildings will project higher, creating new, somewhat larger obstacles along the flight path of migrating and foraging birds. Although all of these buildings are likely to be at a lower height than most migrating birds will be flying, the Project would create potential bird strike hazards at elevations that do not currently exist. With structures up to 195 ft tall and windy, often foggy conditions along San Francisco Bay, the risk of collision for birds would increase. Therefore, the Project could result in the creation of a new strike hazard for migrating birds that could result in the loss of substantial numbers of birds over the life of the Project. Additionally, operating effects associated with the lighting of the Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201058 buildings can alter the flight patterns of migratory birds and potentially increase bird strike collisions with the tall buildings. Although large-scale injury or mortality of birds due to collisions with buildings has not been reported from the West Coast, depending on the design of the buildings there is some potential for such mortality to occur in the absence of mitigation measures. Because of these potential effects, the Project is considered to have a potentially significant impact to migratory birds. To avoid and minimize impacts to migrating and foraging birds as a result of Project construction, the following measures will be implemented: Mitigation Measure 3A. Lighting Measures to Reduce Impacts to Birds. During design of any building greater than 100 feet tall, the Project Applicant shall consult with a qualified biologist experienced with bird strikes and building/lighting design issues to identify lighting- related measures to minimize the effects of the building’s lighting on birds. Such measures, which may include the following and/or other measures, will be incorporated into the building’s design and operation. x Use strobe or flashing lights in place of continuously burning lights for obstruction lighting. Use flashing white lights rather than continuous light, red light, or rotating beams. x Install shields onto light sources not necessary for air traffic to direct light towards the ground. x Extinguish all exterior lighting (i.e., rooftop floods, perimeter spots) not required for public safety. x When interior or exterior lights must be left on at night, the operator of the buildings shall examine and adopt alternatives to bright, all-night, floor-wide lighting, which may include: o Installing motion-sensitive lighting. o Using desk lamps and task lighting. o Reprogramming timers. o Use of lower-intensity lighting. x Windows or window treatments that reduce transmission of light out of the building will be implemented to the extent feasible. Mitigation Measure 3B. Building Design Measures to Minimize Bird Strike Risk. During design of any building greater than 100 feet tall, the Project Applicant will consult with a qualified biologist experienced with bird strikes and building/lighting design issues to identify measures related to the external appearance of the building to minimize the risk of bird strikes. Such measures, which may include the following and/or other measures, will be incorporated into the building’s design. x Use non-reflective tinted glass. Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201059 x Use window films to make windows visible to birds from the outside. x Use external surfaces/designs that “break up” reflective surfaces rather than having large, uninterrupted areas of surfaces that reflect, and thus may not appear noticeably different (to a bird) from, the sky. PROGRAMMATIC ANALYSIS Key Assumptions The following impact analysis is based on several key assumptions: x The tallest of the new office/R&D buildings to be constructed outside the Phase I area will be no more than 10 stories high. x Lighting will be in conformance with the Master Plan’s lighting guidelines. IMPACTS FOUND TO BE LESS THAN SIGNIFICANT Impacts to Developed/Landscaped, California Annual Grassland/Coyote Brush Scrub, and Non-jurisdictional Armored Rock Levee Slope Habitats Portions of the Project site outside of the Phase I boundary, which comprise the programmatic components of the Project site, contain 37.11 ac of developed/landscaped, 4.54 ac of California annual grassland/coyote brush scrub, and 1.04 ac of armored rock levee slope habitats. As a result, there is some potential for some or all of these habitats to be lost or modified due to the construction of buildings, installation of landscaping, and other activities. These habitats are located within the Project area but outside of the Phase I boundary and above the approximate limits of USACE jurisdiction. The acreages of these habitats that will be impacted are unknown; the provided acreages are the maximum possible acreages that could be impacted by programmatic components of the Project. These impacts will reduce the extent of these habitat types on the Project site, and will result in a reduction in abundance of some of the common wildlife species that use the site. However, these habitat types are relatively abundant and widespread regionally, and none of these habitats represents particularly sensitive, valuable (from the perspective of providing important wildlife habitat), or exemplary occurrences of these habitat types. Therefore, impacts to these habitats, and the loss of potential nesting, roosting, and foraging opportunities associated with such habitats, are not considered significant. Impacts to Certain Special-status Wildlife Species and Their Habitats As discussed above for the Phase I component of the Project, several terrestrial special-status species may use the Project area as transients or migrants, or may occur in very low numbers, but are not expected to breed at the site or to be present in any numbers, and thus would not be impacted significantly by Project activities. These species include the American peregrine falcon, black skimmer, harlequin duck, northern harrier, Vaux’s swift, yellow warbler, and tricolored blackbird. The white-tailed kite and loggerhead shrike could possibly also forage in the portion of the Project site outside the Phase I area, but they are not expected to nest here. However, as discussed previously, Project construction would not result in injury or mortality of Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201060 any individuals of these species, which are mobile enough to avoid construction equipment. There would be no substantial loss of foraging or non-breeding habitat for any of these species, as the Project footprint primarily includes already developed and/or heavily impacted areas. As a result, the Project’s impacts do not meet the CEQA standard of having a substantial adverse effect on these species’ populations, and the Project will have a less than significant impact on these species. Impacts to Habitat for and Individuals of Certain Potentially Nesting Special-Status Birds As discussed above for the Phase I component of the Project, some special-status bird species could potentially nest in or adjacent to the Project area but are not expected to be significantly impacted by the Project. These species include the San Francisco common yellowthroat, Alameda song sparrow, and Bryant’s savannah sparrow, which could potentially nest in very low numbers in wetland vegetation at the periphery of the site. However, because the amount and quality of habitat for these species being impacted is low, and the number of nesting individuals that could be disturbed is very small, the Project’s impacts would not substantially reduce regional populations of these species, and thus these impacts do not meet the CEQA standard of having a substantial adverse effect on these species. Although the loss of any active nests of protected birds would be in violation of federal and state laws (see Regulatory Setting above), impacts to these species and their habitats would not be considered a significant impact under the CEQA. Impacts of Lighting on Terrestrial and Aquatic Animals The effects of increased lighting on terrestrial and aquatic animals, as discussed above for the Phase I component of the Project, would also apply to any new lighting provided by programmatic Project activities. As discussed above, any wildlife currently using the site is habituated to the lighting present within this urban area, and the Project incorporates guidelines for the design of lighting to minimize light pollution in areas other than those intended to be lit. Because there is already a substantial amount of artificial lighting at Oyster Point, the implementation of these guidelines will prevent the installation of new lighting from substantially increasing lighting levels, and from impacting terrestrial and aquatic species. Therefore, impacts from increased lighting levels on wildlife will be less than significant. Impacts of Increased Recreational Disturbance on Wildlife The effects of increased recreational disturbance on wildlife, as discussed above for the Phase I component of the Project, would also apply to the programmatic Project activities. Although the construction of new office/R&D facilities as part of the programmatic portion of the Project would result in an increase in the number of recreational users of bayside areas in the Oyster Point vicinity, there is already a substantial amount of human activity at Oyster Point, and wildlife that is present at Oyster Point and in surrounding areas is already largely habituated to high levels of human activity. Increased use of trails or other areas that are already fairly heavily used by people is thus not expected to reduce the use of such areas by wildlife. Therefore, an increase in recreational users of the Bay Trail and other areas adjacent to wildlife habitat resulting from construction of the Project is not expected to have a substantial effect on wildlife in these areas. Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201061 IMPACTS FOUND TO BE LESS THAN SIGNIFICANT WITH MITIGATION Impacts to Northern Coastal Salt Marsh, Open Water, and Jurisdictional Armored Rock Levee Slope Habitats A total of 1.74 acres of northern coastal salt marsh, 0.27 acres of open water (including intertidal habitats), and 0.76 acres of armored rock levee slope below the approximate limits of USACE jurisdiction are present within the Project area outside of the boundaries of Phase I activities. While the actual acreage of impacts to these sensitive/jurisdictional habitats is unknown, it is possible that these habitats could be impacted due to the construction of buildings, marina improvements, Bay Trail improvements, landscaping, and other activities. Additional wetland and open water habitat, within the “Additional Study Area” but outside the Project boundaries (see Figure 2), could potentially be impacted by marina improvements, such as addition or replacement of piers and reconstruction of docks, and by shading from such structures. Due to the ecological importance of wetland and aquatic habitats, such impacts would be potentially significant. The following mitigation measures will reduce these impacts to a less-than- significant level. Mitigation Measure 4A. Delineate Jurisdictional Boundaries. Prior to construction of any programmatic Project elements that are expected to potentially have direct impacts on USACE jurisdictional habitats, a focused delineation will be performed to determine the precise limits of USACE jurisdiction at the site, and USACE approval of the jurisdictional boundaries will be obtained. Mitigation Measure 4B. Impact Avoidance/Minimization. Future Project elements will be designed to avoid and minimize impacts to these sensitive habitats to the extent practicable while still accomplishing Project objectives. Mitigation Measure 4C. Restoration of Temporarily Impacted Wetland/Aquatic Habitats. USACE-jurisdictional areas that are temporarily impacted during construction of programmatic elements will be restored to preexisting contours and levels of soils compaction following build- out. The means by which such temporarily impacted areas will be restored shall be described in the mitigation plan described in Measure 4D below. Mitigation Measure 4D. Compensation for Permanently Impacted Wetland/Aquatic Habitats. Unavoidable permanent fill of all habitats within USACE jurisdiction will be replaced at a minimum 1:1 (mitigation area: impact area) ratio by creation or restoration of similar habitat around San Francisco Bay. Any aquatic, marsh, or mudflat habitat areas experiencing a net increase in shading as a result of docks or other structures constructed over or on the water will require compensatory mitigation at a 0.5:1 (mitigation area: impact area) ratio; this ratio is less than the 1:1 required for permanent filling of such habitats because shaded areas are expected to retain some ecological habitat value. Mitigation could be achieved through a combination of on- site restoration or creation of wetlands or aquatic habitats (including removal of on-site fill or structures, resulting in a gain of wetland or aquatic habitats); off-site restoration/creation; funding of off-site restoration/creation projects implemented by others; and/or mitigation credits purchased at mitigation banks within the San Francisco Bay Region. Because impacts to aquatic Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201062 habitats on-site could also potentially impact special-status fish and EFH (see Impacts to Essential Fish Habitat and Special-Status Fish below), all compensatory mitigation for impacts to aquatic habitat must also provide habitat for green sturgeon, Central California Coast steelhead, and longfin smelt that is of a quality at least as high as that impacted. For funding of off-site improvements or purchase of mitigation bank credits, the Project Applicant shall provide written evidence to the City that either (a) compensation has been established through the purchase of a sufficient number of mitigation credits in a mitigation bank to satisfy the mitigation acreage requirements of the Project activity, or (b) funds sufficient for the restoration of the mitigation acreage requirements of the Project activity have been paid to an entity implementing a project that would create or restore habitats of the type being impacted by the Project. For areas to be restored to mitigate for temporary or permanent impacts, the Project Applicant shall prepare and implement a mitigation plan. The Project Applicant shall retain a restoration ecologist or wetland biologist to develop the mitigation plan, and it shall contain the following components (or as otherwise modified by regulatory agency permitting conditions): 1. Summary of habitat impacts and proposed mitigation ratios, along with a description of any other mitigation strategies used to achieve the overall mitigation ratios, such as funding of off-site improvements and/or purchase of mitigation bank credits 2. Goal of the restoration to achieve no net loss of habitat functions and values 3. Location of mitigation site(s) and description of existing site conditions 4. Mitigation design: x Existing and proposed site hydrology x Grading plan if appropriate, including bank stabilization or other site stabilization features x Soil amendments and other site preparation elements as appropriate x Planting plan x Irrigation and maintenance plan x Remedial measures/adaptive management, etc. 5. Monitoring plan (including final and performance criteria, monitoring methods, data analysis, reporting requirements, monitoring schedule, etc.) 6. Contingency plan for mitigation elements that do not meet performance or final success criteria. Impacts to Migratory Birds from Buildings and Lighting As discussed above for the Phase I component of the Project, there is potential for injury or mortality of birds due to collisions with artificial structures such as buildings as birds engage in long-distance movements (such as migration) and daily movements between roosting and foraging habitats. The existing structures at Oyster Point are relatively low, and the risk of bird strikes under existing conditions is expected to be relatively low. Any buildings constructed by the programmatic components of the Project that will project higher than the existing buildings will create new, somewhat larger obstacles along the flight path of migrating and foraging birds. Although any new buildings are likely to be at a lower height than most migrating birds will be Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201063 flying, the Project could create potential bird strike hazards at elevations that do not currently exist. Therefore, the programmatic portion of the Project could result in the creation of a new strike hazard for migrating birds that could result in the loss of substantial numbers of birds over the life of the Project. Additionally, operational effects associated with the lighting of the buildings can alter the flight patterns of migratory birds and potentially increase bird strike collisions with the tall buildings. Depending on the design of the buildings there is some potential for such mortality to occur in the absence of mitigation measures. Because of these potential effects, the programmatic components of the Project are considered to have a potentially significant impact to migratory birds. To avoid and minimize impacts to migrating and foraging birds as a result of programmatic Project construction, Mitigation Measures 3A and 3B, described above, shall be implemented during design and construction of the programmatic components of the Project, thus reducing this impact to a less than significant level. Impacts to Aquatic Species Due to Degradation of Water Quality during Construction Construction in and near drainage channels, storm drains, or the Bay could have a significant adverse effect on water quality in the Bay within and adjacent to the Project site due to increased turbidity, if ground-disturbing activities occur during the wet season, if soil is allowed to enter channels or storm drains, or if dredging or other substrate-disturbing activities take place within the Bay. Increases in turbidity resulting from construction constitutes a potentially significant impact to aquatic wildlife species, including special-status fish species such as steelhead and sensitive native species such as the Olympia oyster. Water quality degradation could also negatively impact eelgrass beds if they occur in the Project area. Due to the ecological importance of these aquatic habitats and sensitive resources, such impacts would be potentially significant. Implementation of Mitigation Measures 1A through 1C, described above, would reduce this impact to a less-than-significant level. Impacts to Essential Fish Habitat and Special-Status Fish The tidal aquatic habitats adjacent to the Project site are considered EFH by the NMFS. If programmatic Project elements include construction activities in the waters of the Bay, such activities could adversely impact Essential Fish Habitat in the Project area. Special-status fish species that occur in the Project vicinity and could potentially be impacted by programmatic elements of the Project are the southern green sturgeon, the Central California Coast steelhead, and the longfin smelt. Habitat for occasional dispersing individuals of all three species is similarly located in open waters and estuarine habitats of the San Francisco Bay along the boundaries of the Project area. In combination with the BMPs for water quality described above, the following mitigation measures, adapted from Amendment 11 of the West Coast Groundfish Plan (PFMC 2006) and Appendix A of the Pacific Coast Salmon Plan (PFMC 2003), will reduce impacts to EFH and special-status fish to a less than significant level. Unless modified by the federal permitting agencies (NMFS or USACE), these measures shall be implemented during construction by the Project Applicant. Mitigation Measure 5A. Avoidance of Salmonid Migration Periods. In-water work when juvenile salmonids are moving through the Bay on the way to the open ocean or when groundfish Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201064 and prey species could be directly impacted shall be avoided. Because steelhead are potentially present, the allowed dredge window for this area of the San Francisco Bay is June 1 through November 30. All in-water construction shall occur during this window. If completion of in- water work within this period is not feasible due to scheduling issues, new timing guidelines shall be established and submitted to the NMFS and CDFG for review and approval. Mitigation Measure 5B. Worker Training. Personnel involved in in-water construction and deconstruction activities shall be trained by a qualified biologist in the importance of the marine environment to special-status fish, and birds and the environmental protection measures put in place to prevent impacts to these species, their habitats, and EFH. The training shall include, at a minimum, the following: 1.A review of the special-status fish and sensitive habitats that could be found in work areas 2.Measures to avoid and minimize adverse effects to special-status fish, birds, their habitats, and EFH 3.A review of all conditions and requirements of environmental permits, reports, and plans (i.e., USACE permits) Mitigation Measure 5C. Avoidance of Areas of Wetland and Aquatic Vegetation. All construction equipment used in conjunction with in-water work (pipelines, barges, cranes, etc.) shall avoid wetlands, marshes, and areas of sub-aquatic vegetation (including eelgrass beds). Pile-Driving Impacts to Fish and Marine Mammals If programmatic project elements include construction activities in the waters of the Bay, individuals of special-status fish species could suffer injury or mortality due to construction activities including percussive noise due to jackhammering, pile-driving, or other percussive activities. The in-water pressure wave, if of sufficient magnitude, can injure or kill fish. Pressure waves have an actual force associated with them and the stronger the force, the more likely they are to damage sensitive tissues in aquatic species. Pressure waves interact with fish in the water column, causing behavioral and physiological effect such as avoidance, stress, temporary loss of hearing, rupture of swim bladders (air pockets that are used for buoyancy), the formation of bubbles in the circulatory system and corresponding rupturing of blood vessels, traumatic brain injuries, and death. Current criteria indicate that sound levels of 183 decibels can injure or kill fish (Fisheries Hydroacoustic Working Group 2008). Marine mammals, which have sensitive hearing, can also easily be disturbed by sound-generated pressure waves, although effects from Project activities would be unlikely to cause injury or mortality of these species. Due to the number of fish that could be present near in-water construction areas, the potential presence of special-status fish, and the sensitivity of marine mammals such as harbor seals and California sea lions, such impacts are potentially significant. To reduce impacts to special-status fish and marine mammal species due to percussive activities to less than significant levels, the following measures shall be employed. Mitigation Measure 6A. Incorporation of Design Considerations that Minimize the Need for Percussive Construction Techniques. If programmatic Project elements include Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201065 construction of structures that require percussive techniques, structure design shall adhere to the following principles to the greatest extent practicable: 1. Engineer structures to use fewer or smaller piles, where feasible, and preferably, solid piles 2. Design structures that can be installed in a short period of time (i.e., during periods of slack tide when fish movements are lower). 3. The City, with consultation from a qualified biologist who is familiar with marine biology, shall review the final Project design to ensure that these design requirements have been incorporated into the Project. Mitigation Measure 6B. Utilization of Construction Tools and Techniques that Minimize Percussive Noise. If programmatic Project elements include construction of structures that require percussive techniques, construction activities shall employ the following techniques to the greatest extent practicable. 1. Drive piles with a vibratory device instead of an impact hammer if feasible, and use a cushioning block between the hammer and the pile. 2. Restrict driving of steel piles to the June 1 to November 30 work window, or as otherwise recommended by the NMFS (driving of concrete piles would not be subject to this condition). 3. If steel piles must be driven with an impact hammer, an air curtain shall be installed to disrupt sound wave propagation, or the area around the piles being driven shall be dewatered using a coffer dam. The goal of either measure is to disrupt the sound wave as it moves from water into air. 4. If an air curtain is used, a qualified biologist shall monitor pile driving to ensure that the air curtain is functioning properly and Project-generated sound waves do not exceed the threshold of 180183-decibels generating 1 micropascal (as established by NMFS guidelinesthe Fisheries Hydroacoustic Working Group; 2008). This shall require monitoring of in-water sound waves during pile driving. 5. Use of fewer piles, or smaller piles, or a different type of pile, with hollow steel piles appearing to create the most impact at a given size 6. Driving piles when species of concern are absent 7. Use of a vibratory hammer rather than an impact hammer 8. Use of a cushioning block between hammer and pile 9. Use of a confined or unconfined air bubble curtain; and 10. Driving piles during periods of reduced currents Impacts to Olympia Oyster Beds There is a known population of Olympia oysters at Oyster Point. In-water construction activities, including activities at the marina and along the shoreline, could potentially impact oysters through the removal of substrate supporting oysters, smothering of oyster beds with fill, or degradation of water quality. Such oysters, including their larvae, provide food, refugia, and attachment sites for a number of aquatic organisms and filter nutrients and pollutants from the water. As a result, these oysters perform a valuable function to the Bay ecosystem, and impacts Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201066 to oysters from programmatic activities are potentially significant. To mitigate these impacts to less than significant levels, the following measures shall be implemented: Mitigation Measure 7A. Implementation of Best Management Practices for Water Quality. The water quality Best Management Practices described above in Measure 1A shall be followed to the greatest extent practicable. If increases in turbidity due to Project activities cannot be minimized, Measures 7C and 7D shall be implemented. Mitigation Measure 7B. Avoidance of Suitable Oyster Habitat. To the greatest extent practicable, project activities shall avoid removing or disturbing riprap and other rocky substrates that serve as suitable oyster habitat. If impacts to oysters and their habitat are unavoidable, measures 7C and 7D shall be implemented. Mitigation Measure 7C. Native Oyster Surveys. A detailed survey for native oysters shall be conducted in all suitable substrates within the project area. This survey shall be conducted by a qualified oyster biologist at low tides that expose the maximum amount of substrate possible. Surveys can be conducted at any time of year, but late summer and early fall are optimal because newly settled oysters are detectable. This survey shall occur before any construction within aquatic habitats takes place to establish a baseline condition. If few or no oysters are observed on hard substrates that would remain in place after construction, no further mitigation is required. Mitigation Measure 7D. Replacement of Suitable Oyster Habitat. If more than 100 oysters would be removed or are in areas where construction-generated sediment could settle out onto the oysters, compensatory mitigation shall be provided by the Project Applicant at a minimum 1:1 ratio. The Project Applicant shall retain a qualified oyster biologist to develop an Oyster Restoration Plan that shall be reviewed and approved by the City. This Plan shall include site selection, substrate installation, and monitoring procedures, and include the following components (unless otherwise modified by NMFS): 1.A suitable site for installation of replacement substrate would be one with adequate daily tidal flow, a location that would not be affected by maintenance dredging or other routine marina maintenance activities, and one that is lacking in appropriate settlement substrate. A location outside of the breakwaters or in association with any eelgrass mitigation sites would be appropriate. 2.Although oysters may settle on a variety of materials, the most appropriate for restoration purposes is oyster shell. This is typically installed by placing the shell into mesh bags that can then be placed in piles on the seafloor of the mitigation site. Enough shell shall be installed under the guidance of a qualified oyster biologist to make up for the loss attributable to the Project. Mitigation shall occur after construction of all in-water elements of the Project. 3.The restoration site shall be monitored on a regular basis by a qualified oyster biologist for a minimum of two years, or until success criteria are achieved if they are not achieved within two years. Monitoring shall involve routine checks (bi-monthly during the winter and monthly during the spring and summer) to evaluate settlement, growth, and survival on the mitigation site. Success shall be determined to have been Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201067 achieved when settlement and survival rates for oysters are not statistically significantly different between the mitigation site and the populations being impacted. Impacts to Eelgrass Beds Although no eelgrass beds or patches have been mapped closer than 3 mi from the Project area, the NMFS (2010) considers portions of Oyster Point to offer suitable eelgrass habitat, and there is some evidence that eelgrass populations in the Bay are expanding (Merkel & Associates 2004). Thus, we cannot rule out the possibility that eelgrass patches or beds have become established, or will become established prior to the initiation of programmatic activities, in or near the Project area. In-water construction activities that result in increased turbidity could potentially result in adverse effects to eelgrass by covering eelgrass with sediment. Because eelgrass beds provide nursery habitat for a variety of fish species, they are very important to the Bay ecosystem, and impacts to eelgrass beds are thus potentially significant. In addition to the implementation of the avoidance and minimization measures for water quality described above, the following measures will be implemented to reduce impacts to eelgrass beds to less than significant levels. Mitigation Measure 8A. Water Quality Best Management Practices for Eelgrass. In addition to the water quality BMPs described above in Measure 1A, the following BMPs will minimize impacts to any eelgrass beds in the Project area. 1.Conduct all in-water work during periods of eelgrass dormancy (November 1-March 31) [Note: the majority of this period conflicts with the period during which in-water activities should not occur to avoid impacts to salmonids; only the period November 1-30 would avoid impacts during sensitive periods for both taxa.] 2.Install sediment curtains around the worksite to minimize sediment transport If these BMPs are not feasible, or if Project activities will occur in aquatic areas outside of the marina, the following measures shall be undertaken. Mitigation Measure 8B. Eelgrass Survey.Prior to any construction activities in aquatic habitats, a survey for eelgrass beds or patches will be conducted within 750 ft of expected aquatic construction activities. The survey shall be conducted by a biologist(s) familiar with eelgrass identification and ecology and approved by NMFS to conduct such a survey. Survey methods shall employ either SCUBA or sufficient grab samples to ensure that the bottom was adequately inventoried. The survey shall occur between August and October and collect data on eelgrass distribution, density, and depth of occurrence for the survey areas. The edges of any eelgrass beds or patches shall be mapped. At the conclusion of the survey a report shall be prepared documenting the survey methods, results, and eelgrass distribution, if any, within the survey area. This report shall be submitted to NMFS for approval. If Project activities can be adjusted so that no direct impacts to eelgrass beds would occur, no further mitigation would be required. If direct impacts to eelgrass beds cannot be avoided, the following measures shall be implemented. Mitigation Measure 8C. Compensatory Eelgrass Mitigation. If direct impacts to eelgrass Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201068 beds cannot be avoided, compensatory mitigation shall be provided in conformance with the Southern California Eelgrass Mitigation Policy. Mitigation shall entail the replacement of impacted eelgrass at a 3:1 (mitigation: impact) ratio on an acreage basis, based on the eelgrass mapping described in mitigation measure 8B above, and detailed designs of the feature(s) that would impact eelgrass beds. Such mitigation could occur either off site or on site (NMFS 2005b). Off-site mitigation could be achieved through distribution of a sufficient amount of funding to allow restoration or enhancement of eelgrass beds at another location in the Bay. If this option is selected, all funds shall be distributed to the appropriate state or federal agency or restoration-focused non-governmental agency (i.e., CDFG restoration fund, California Coastal Conservancy, Save the Bay, etc). The Project Applicant shall provide written evidence to the City that either a) compensation has been established through the purchase of a sufficient number of mitigation credits to satisfy the mitigation acreage requirements of the Project activity, or funds sufficient for the restoration of the mitigation acreage requirements of the Project activity have been paid. These funds shall be applied only to eelgrass restoration within the Bay. If on-site mitigation is selected as the appropriate option, the Project Applicant shall retain a qualified biologist familiar with eelgrass ecology to prepare and implement a detailed Eelgrass Mitigation Plan. Unless otherwise directed by NMFS, the Eelgrass Mitigation Plan shall follow the basic outline and contain all the components required of the Southern California Eelgrass Mitigation Policy (as revised in 2005), including: identification of the mitigation need, site, transplant methodology, mitigation extent (typically 3:1 on an acreage basis), monitoring protocols (including frequency, staffing, reviewing agencies, duration, etc), and success criteria. A draft Eelgrass Mitigation Plan shall be submitted to NMFS, for its review and approval prior to implementation, with a copy to the City. Once the plan has been approved, it shall be implemented in the following appropriate season for transplantation. Restored eelgrass beds shall be monitored for success over a 5-year period. CUMULATIVE IMPACTS Cumulative impacts arise from a concatenation of impacts from past, current, and reasonably foreseeable future projects in the region. With implementation of the mitigation measures above, no significant impacts are expected as a result of project-level or program-level implementation of the Oyster Point Business Park and Marina Area Redevelopment Master Plan. The proposed Oyster Point Business Park and Marina Area Redevelopment Master Plan will not result in a cumulatively considerable contribution to cumulative impacts to biological resources. With the exception of isolated protected open spaces, the Project vicinity is largely built up, and few areas for new development remain. However, infill development and redevelopment of existing areas are likely to occur in the Project vicinity. For example, the Candlestick Point- Hunters Point Shipyard redevelopment project is proposed just north of the Project site (City of San Francisco 2010). All of these Projects are each expected to complete (or have completed) their own separate CEQA reviews, and to address any potential impacts therein by mitigating them to a less than significant level. Project impacts will result primarily from the loss or modification of regionally abundant terrestrial habitats and the associated modification of wildlife communities dominated by Oyster Point Redevelopment Master Plan EIR Biological Resources Report H. T. Harvey & Associates 21 September 201069 regionally abundant species. Due to the abundance of these species and habitat types regionally, the Project will not contribute to cumulative impacts on these resources. Wetland and aquatic habitats of San Francisco Bay, which could be impacted by the Project, are of particular ecological importance, have undergone more substantial modification by human activities, and are less extensive regionally than the upland habitats that will be impacted by the Project. However, not only will the Project mitigate its contribution to cumulative impacts to these resources, but restoration projects such as the South Bay Salt Ponds Restoration Project and others throughout San Francisco Bay will enhance and restore Bay habitats and animal communities in the coming decades, thus helping to reverse cumulative impacts on these resources.

Redevelopment Master Plan and Project January 19, 2011 Prepared by California Water Service Company 341 North Delaware Ave San Mateo, California 94401 2 Introduction The City of South San Francisco (City) through its consultant, Lamphier Gregory, has requested California Water Service Company (Cal Water) prepare a Water Supply Assessment (WSA) in accordance with California SB 610 requirements for the proposed Oyster Point Specific Plan (OPSP) which is comprised of the Oyster Point Business Park and Marina Area. The site of the OPSP, including the Phase I Project and all subsequent phases of development is part of the City’s “East of 101” planning area. The approximately 80 acre Plan site is located about 3/4 of a mile east of Highway 101, at the eastern end (Bay side) of Oyster Point and Marina Boulevards. The Oyster Point Business Park covers 25 acres of the OPSP area. It contains privately owned five single-story light-industrial buildings at 375/377, 379, 384, 385 and 389 Oyster Point Boulevard that were developed in the early 1980s totaling 403,212 square feet of space and surrounding parking. Currently, these buildings are occupied by a variety of light industrial, office, and research and development (R&D) tenants. Other than roadway elements, the 48 acre Oyster Point Marina constitutes the remainder of the OPSP area. This land served as a municipal landfill for the City of South San Francisco from 1956 until it stopped accepting waste in 1970. The Marina is owned by the City of South San Francisco and managed through a Joint Powers Agreement with the San Mateo County Harbor District. Currently, this area includes a variety of uses: a dry boat storage area, a marine support services building, two small office buildings, Oyster Point Inn, a 30 room inn and banquet hall, Oyster Point Bait and Tackle shop, a boat and motor mart and the Oyster Point Yacht Club, totaling 74,360 square feet. The remaining area is vacant or serves as parking for the docks, boat ramp, and the Bay Trail at the Oyster Point Marina. The Oyster Cove Marina is privately owned and located to the west of the Oyster Point Business Park; it contains 235 berths. The Oyster Point Marina is located on the north side of the Oyster Point Marina area and contains 600 berths, a boat ramp, fuel dock and fishing pier. The South San Francisco Ferry Terminal with service to/from San Francisco and the East Bay is currently scheduled to be completed at the Oyster Point Marina in early 2011. This Ferry Terminal is a separate project with its own environmental review. The proposed project is to be implemented in four (4) phases includes demolition of existing commercial and recreational buildings. The Existing Conditions Aerial photo (SKS June 1, 2010) and Proposed Development Phases (Shorenstein/SKS September 10, 2009) show location features and development sequence. No set timeframe has been given for Phases II, III, and IV. As proposed, the OSPS will be a public and private redevelopment comprised of the uses shown in Table 1 below. A split of 60% Research & Development and 40% Office space use is proposed in the specific plan. The total for all Office and R&D building area cannot exceed 2,300,000 square feet. 3 Table 1: Oyster Point Specific Plan Proposed Land Uses Building Size (square feet if not otherwise specified) Uses to Remain Oyster Point Bait and Tackle 1,440 Oyster Cove Marina 235 berths Oyster Point Marina 600 berths Phase I Office/R&D Building 508,000-600,000 Auxiliary Commercial 10,000 Oyster Pt Marina Beach 3.1 acres Phases II, III, IV New Hotels 350 rooms Commercial/Retail/Restaurant in Hotel 40,000 Office/R&D Building (Phase II) 700,000 Office/R&D Building (Phase III) 525,000 Office/R&D Building (Phase IV) 517,000 Recreation Fields 4.8 acres Uses to Remain until Hotel Construction, then be rebuilt on Site Oyster Point Yacht Club 4,000 Oyster Point Maintenance 2,500 Following is a more specific breakdown of the proposed project: Private development including new office/research and development (R&D) buildings in the western portion of the site: x Demolition of the existing inn located at 425 Marina Drive, the office buildings at 360 Oyster Point Boulevard and 401 Marina Boulevard, the boat and motor mart at 671 Marina Boulevard, the Yacht Club at 911 Marina Boulevard, and the light-industrial buildings at 375-389 Oyster Point Boulevard, x New public roadway alignment (and utility infrastructure) of Oyster Point Boulevard and Marina Drive, including relocation of sewer pump station #1 adjacent to 377 Oyster Point Boulevard, x Office/R&D buildings with a Floor Area Ratio (FAR) of up to 1.25 across the 41 acres of private land area, totaling up to 2,300,000 square feet of building space, including 10,000 square feet of accessory commercial uses, x Four phases of approximately 500,000 to 700,000 square feet each, x Each phase will include or have access to courtyards, plazas, shuttle bus stops, and/or structured parking, x Dedication and construction of an approximately 3.1 acre parcel for use as waterfront public open space. 4 x Site preparation and/or construction on the former landfill site could involve disturbance and relocation of landfill refuse on- or off-site.

Future Hotel Site: x The 4.7-acre site to the east of the sports fields will be graded to allow for a future hotel and retail complex. On this site, the Yacht Club structure and the Harbor District garage, yard and surrounding access roads remain intact through Phase I. 6 This OPSP is not specifically covered in Cal Water’s 2006 South San Francisco (SSF) District Urban Water Management Plan (UWMP), which was adopted on December 15, 2006; therefore, its water requirements and how they would be met are addressed in this Water Supply Assessment (WSA). The SSF District UWMP document provides historic and forecasted water demand and supply data and analyses and can be referenced for more detailed information on those topics. Cal Water updates its Urban Water Management Plans every three to five years. Senate Bills 610 (Chapter 643, Statutes of 2001) (SB 610) and Senate Bill 221 (Chapter 642, Statutes of 2001) (SB 221) amended state law, effective January 1, 2002, to improve the link between information on water supply availability and land use development decisions made by cities and counties. SB 610/SB 221 are companion measures that require detailed information regarding water supply availability be provided to local public agency decision-makers prior to approval of development projects that meet or exceed any of the following criteria: 1.A residential development of more than 500 dwelling units. 2.A shopping center or business establishment employing more than 1,000 persons or having more than 500,000 square feet. 3.A commercial office building employing more than 1,000 persons or having more than 250,000 square feet of floor space. 4.A hotel or motel with more than 500 rooms. 5.An industrial, manufacturing or processing plant or industrial park planned to house more than 1,000 persons occupying more than 40 acres of land or having more than 650,000 square feet of floor area. 6.A mixed-used project that includes one or more of the projects specified above. 7.A project that would demand an amount of water equivalent to, or greater than the amount of water required by a 500 dwelling unit project. Since the proposed Oyster Point Redevelopment Project development project exceeds several criteria, a SB 610 WSA and a SB 221 verification document are required. A SB 610 WSA must address the adequacy of the water supply to meet estimated demands of the proposed project over the next 20 years in addition to those of Cal Water’s existing customers and other anticipated future users under normal, single dry year and multiple dry year conditions. (Water Code §10911(a).) SB 610 and SB221 require that the information developed to address the adequacy of the water supply question be included in the administrative record that serves as the evidentiary basis for an approval action by the local public agency. Both state bills recognize local control and decision-making regarding the availability of water for projects and the approval of projects.Under SB 610, water supply assessments must be furnished to local governments for inclusion in any required California Environmental Quality Act (CEQA) documents. Water Code 10910 (a) requires that any city or county that determines that a project, as defined in Section 10912, is subject to CEQA shall comply with the requirements of this part of the water code. Under SB 221, approval by a city or county of certain 7 residential subdivisions requires an affirmative written verification of sufficient water supply. An SB 221 verification document is required for tentative tract map approval. In December 2010, the City requested Cal Water prepare a SB 610 WSA for the OPSP. Cal Water submitted a Draft WSA for the proposed development to the City for review approximately 30 days later. (Water Code 10910(g) requires the water supplier to prepare the assessment within 90 days of request.) On January 19, 2011, Cal Water received review comments from the City. Cal Water subsequently revised the Draft WSA to address those comments resulting in this WSA document. As referenced, Cal Water adopted its current SSF District UWMP for the District on December 15, 2006. Per Section 10910(c) (3) of the Water Code, this water supply assessment is based on information contained in the UWMP and from other more recent sources cited here. Following is a description of the proposed Oyster Point Redevelopment Project development project, its projected water demands, and a description and assessment of the proposed water supply to meet those and all other forecasted demands in the SSF District in accordance with the requirements of SB 610. OPSP Implementation Schedule Available information on the OPSP did not include a specific implementation schedule for all four development phases. To be responsive to WSA requirements, a schedule was developed and is shown in Table 2.

Water Demand Forecast: Oyster Point Specific Plan For the proposed new facilities, it is assumed that water usage rates for new office space, R&D laboratories, commercial and retail uses and landscape irrigation will be the same as similar existing facilities in the Oyster Point area. For the December 2008 South San Francisco Gateway Business Park project WSA, actual water use records were obtained for specific buildings along with interior square footage. The following is a summary of this data. For the period from July 2007 – June 2008 (1 year or 365 days), total internal metered water use for five existing buildings at 700, 1000, 750, 800 and 850 Gateway Boulevard was 3,392,180 gallons for an area of 234,013 square feet. Overall average annual day water use was 0.04 gallons/day/ft2. The existing building at 700 Gateway Blvd is nearly all office space use. The building area is 55,098 square feet and annual water use from July 2007 – June 2008 was 722, 568 gallons or 0.036 gallons/day/ft2. The existing building at 800 Gateway Blvd is nearly all biotechnology research and development laboratory space use. The building area is 45,400 square feet and annual water use from July 2007 – June 2008 was 1,039,720 gallons or 0.063 gallons/day/ft2. For the July 2007 – June 2008 period, total landscape irrigation water use was 7,219,192 gallons for an area of 250,143 square feet. Average annual day irrigation water use was: 0.079 gallons/day/ft2. It is assumed that use of the existing average annual day water use rates will be the same in the new development. Therefore, the only change in water demand will be that due to the net increase in building space. Estimating water usage for commercial, retail, restaurants and hotels on a gallons/square feet basis requires characterizing the type and mix of businesses that are anticipated in the development. If the commercial/retail/restaurant/hotel mix has a higher concentration of higher water using businesses such as supermarkets, restaurants, coffee shops, health clubs, etc., the water use factor will be significantly higher than a mix largely comprised of dry goods retail activities such as clothing, shoes, jewelry, sporting goods, drug stores, bookstores, etc. For another development project in Cal Water’s Dominguez District in Torrance, CA, PCR Services Corporation (PCR) using data derived by the County Sanitation Districts of Los Angeles (CCDLA) developed a table of estimated water demand for a variety of commercial activities. Since there was good agreement between the estimate of residential water usage derived from Cal Water data and those developed by PCR using CCDLA data, estimates of water demand for commercial activities developed by PCR using CCDLA factors are used here for the OPSP and are summarized below. 9 Commercial Activities Water Use Factors Average Use Category gallons/sq ft/day Retail: Shopping Center 0.358 Electronic Superstore 0.110 Home Improvement 0.110 Discount Club 0.110 Home Furnishing 0.110 Office Supplies 0.110 Pet Supply 0.110 Supermarket 0.65 Restaurants: High turnover 1.100 Fast Food 1.100 Quality 1.100 Hotel water use has been estimated at 0.50 gallons/sq ft/day.

The district serves the communities of South San Francisco, Colma, a small portion of Daly City, and an unincorporated area of San Mateo County known as Broadmoor, which lies between Colma and Daly City. Figure 2 is a map showing the District’s service areas. 11 Figure 2: South San Francisco District Cal Water designates customer classifications as follows: Single Family Residential Multifamily Residential Commercial Industrial Government Other The residential sector of CWS water service customers includes permanent single and multifamily residents. A variety of land uses exist in the South San Francisco service area. Within the City of South San Francisco, 28 percent of the land is residential, 21 percent industrial, seven-percent commercial, 11 percent is vacant and agricultural land and the balance is for public and utility use. In the City of Colma, approximately 77 percent of the land is used for cemeteries. The balance of the land is for residential, commercial, and public use. The Broadmoor area is primarily residential. Although the South San Francisco District is predominantly surrounded by communities served by other water companies, a few pockets of growth and several areas of redevelopment remain. 12 The average annual services for calendar year 2004 were 16,137. Single family residential services represented 85.5 percent, commercial services 11.6 percent and all other services 2.90 percent. SSF District Water Demand Total district demand is forecasted by multiplying the number of services for each customer class by the demand per service for that class. This method accounts for the significant differences between the demand per service associated with each customer class and the different growth rates for each class. Two growth patterns were considered in the SSF UWMP: 1) 5-year average service connection growth rate, and 2) 10-year average service connection growth rate. The growth rate for the five-year period 2000 to 2004 is 0.02 percent/year. The growth rate for the ten-year period 1996 to 2005 is 0.42 percent/year. Each customer class, such as residential, commercial and other uses, grows at a different rate. Therefore, the use of short-term or long- term growth rates in developing total annual service connections is done on the basis of customer class. The 10-year average service connection growth pattern is used in the updated UWMP for making demand projections because it is more representative of actual growth in the South San Francisco District. The SSF UWMP develops three demand scenarios: low, average and high. The low and high scenarios set the range boundaries for the forecasted demand growth, while the average demand is determined by Cal Water in making a forecast of anticipated demand. Cal Water’s historical methodology for forecasting demand in the SSF District’s for the UWMP is to use the average demand per service by class is combined with the 10-year rate of growth in services by class to arrive at the most probable demand through the year 2040. However, the updated UWMP will focus on the requirements of SB7 which mandates a per capita demand reduction of 20% be accomplished by 2020 and that a baseline and a conservation demand goal be based on using one of four permitted methods. Table 4 shows projected average annual water demand and the SB7 pre-conservation baseline and post conservation demand goal for the SSF District to the year 2030. Table 4 Actual and Forecasted Annual SSF District Water Demand (Acre-Feet) Year Average SB7 Baseline SB7 Goal 2005 8,869 2010 8,463 9,085 9,085 2015 8,980 9,545 9,105 2020 9,205 9,766 8,431 2025 9,433 9,991 8,626 2030 9,668 10,219 8,826 13 The SB7 baseline was determined by combining the forecasted population for the SSF District with the baseline per capita demand of 144 gpcd. Since the SSF District already has a low per capita demand compared to other regional communities the mandated per capita goal is set at 124 gpcd, which represents a 13% reduction in overall demand from the current baseline level. The following analysis demonstrates that the forecasted demand of the OPSP can be considered as part of the SSF District forecasted demand growth. Cal Water used the SB7 Baseline demand, as presented in Table 4 above as the forecasted demand that would occur in the absence of achieving mandated SB7 demand reductions. Water savings generated by the SB7 program are treated as a water supply source. Use of these savings and additional supplies from other sources supports increased demand within the SSF service area. The SB7 Baseline demand for the SSF District in 2015 is 9,545 acre-feet/year (AFY) or 8.52 million gallons per day (mgd). The forecasted demand for 2010 is 9,085 AF, so the forecasted increase in average day demand for the 5-year period 2010 to 2015 is 460 AFY or 0.411 mgd. From Table 3, Phase I OPSP forecasted increase in demand in 2015 is 43,038 gpd or 48.2 AFY. This represents 10.5% (48.2/460) of the projected increase in forecasted SSF District water demand for that period. The SB7 Baseline demand for the SSF District in 2030 is 10,219 AFY or 9.12 mgd so the increase in average day demand from 2010 to 2030 (20-year period) is 1,134 AFY or 1.012 mgd. The OPSP forecasted net increase in demand in 2030 for all four phases is 239,023 gallons/day or 268 AFY. This represents 23.6% (268/1,134) of the projected increase in forecasted SSF District water demand for the 20 year period. With respect to either the 5-year or 20-year forecasts, the OPSP does not represent a significant percentage in the projected increase in District demand. For 2015, it leaves 89.5% of the projected increase in demand for other projects and general growth within the District. For 2030, it leaves 76.4% for other projects and general growth. Therefore, for purposes of this WSA, the increases in water demand due to the OPSP are assumed to be part of Cal Water’s SSF District demand forecast. SSF District Water Supply The South San Francisco District water supply is a combination of purchased water obtained from the San Francisco Public Utilities Commission, groundwater produced from Company owned wells, and SB7 conservation generated supply savings. Table 5 summarizes the projected water supply sources and their annual quantity for the next 20 years assuming that the SB7 forecasted demand is achieved. 14 Table 5: SSF District Water Supplies (AFY) Water Supply Sources 2005 Actual 2010 Actual 2015 2020 2025 2030 San Francisco Public Utilities Commission 8,869 8012 7,604 6,931 7,126 7,326 Cal Water Groundwater Wells 0 451 1,500 1,500 1,500 1,500 SB7 Conservation Savings 0 0 441 1,335 1,365 1,393 Total (SB7 Baseline Demand) 8,869 8,463 9,545 9,766 9,991 10,219 Purchased Water Cal Water purchases treated surface water from the San Francisco Public Utilities Commission (SFPUC). This supply is predominantly from the Sierra Nevada, delivered through the Hetch Hetchy aqueducts, but also includes treated water produced by the SFPUC from its local watersheds and facilities in Alameda and San Mateo Counties. The amount of imported water available to SFPUC’s retail and wholesale customers is constrained by hydrology, physical facilities, and the institutional factors that allocate the water supply of the Tuolumne River. Due to these constraints, the SFPUC is very dependent on reservoir storage to firm-up its water supplies. The SFPUC meets its retail and wholesale water demands through an integrated regional water system that includes water from local Bay Area water sources as well as imported water from Hetch Hetchy reservoir. Local watershed facilities are operated to capture local runoff as well as store imported water. Local reservoirs include: Crystal Springs Reservoir, San Andreas Reservoir, Pilarcitos Reservoir, Calaveras Reservoir, and San Antonio Reservoir. The Raker Act, which authorized the Hetch Hetchy project, prevents a privately owned utility such as Cal Water from receiving water from the Hetch Hetchy system, but allows local sources to be purchased. In addition, Cal Water is subject to the Water Supply Agreement between The City and County of San Francisco and Wholesale Customers in Alameda County, San Mateo County and Santa Clara County. The water purchased is treated by SFPUC prior to delivery to Cal Water. The district takes delivery from SFPUC from eleven metered connections from five SFPUC transmission lines. Supply Guarantee In July 2009, Cal Water along with 29 other Bay Area water suppliers signed a Water Supply Agreement (SFWSA) between The City and County of San Francisco and Wholesale Customers in Alameda County, San Mateo County and Santa Clara County, which replaced the Settlement Agreement and Master Water Sales Contract (Master Contract) with San Francisco that had been in place since 1984. The SFWSA continues the provision to provide a Supply Guarantee of 184 mgd, expressed on an annual average basis to SFPUC wholesale customers collectively. SFPUC retail customers receive 81 mgd as a supply guarantee. Cal Water’s Individual Supply Guarantee (ISG) is 35.68 mgd or 39,967 acre feet per year. 15 The SFPUC can meet the demands of its retail and wholesale customers in years of average and above average precipitation. The SFWSA allows SFPUC to reduce water deliveries during droughts, emergencies and for scheduled maintenance activities. SFPUC’s wholesale customers through their collective organization, the Bay Area Water Supply and Conservation Agency (BAWSCA) during 2010 negotiated the Drought Implementation Plan (DRIP), which will replace the previously adopted Interim Water Shortage Allocation Plan. The SFWSA allocates the required reduction of available water supply between San Francisco’s retail and wholesale customers. The SFWSA established that during a called upon 20% drought reduction, collective wholesale customers face up to a 28% reduction in their available supply, while SFPUC retail customers face only a 2% reduction. The DRIP aggregates the reduction applied to the wholesale customers and allocates it among individual wholesale customers during water shortages of up to 20% of system-wide. Although the DRIP has not yet been adopted by the wholesale customers, it was formulated in unanimous consensus by a BAWSCA committee of designated representatives from each wholesale customer. It is anticipated that the DRIP will be adopted in early 2011. The DRIP uses an allocation process that takes into consideration the wholesale customer’s ISG and the seasonal water use pattern of the wholesale customer’s service area. Communities that use substantially more water in the summer will face a greater reduction in their allocated drought supply. Health and safety adjustments were provided to increase the drought allocation of several wholesale customers that have extremely low ISG values. Much like the previously approved Interim Water Supply Allocation Plan, during a called upon 20% drought reduction because of the seasonal water use pattern of its customers and the recent high demand that has reached or exceeded it’s ISG, Cal Water’s customers face a potential 33% reduction in their available supply. By implementing conservation and seeking outside water supplies that can be transferred into Cal Water’s service area, the magnitude of the potential reduction can be reduced. The SFWSA also calls for implementation of an Interim Supply Allocation (ISA) accompanied by an Environmental Enhancement Fee. If the entire SFPUC service area exceeds the collective supply guarantee of 264 mgd (81 mgd to SFPUC retail and 184 mgd to wholesale), then any individual customer that exceeds their ISA will be assessed the yet to be determined Environmental Enhancement Fee. Cal Water’s ISA has been set at its ISG of 35.68 mgd. This is intended to be an incentive to implement conservation. In 2010, the collective SFPUC service area used 214.4 mgd; the five year average use is 237.6 mgd. Groundwater Groundwater is extracted from Cal Water owned wells the Merced Formation of the Colma Creek Basin, a sub-basin of the Merced Valley Groundwater Basin, which is popularly referred to as the Westside Basin. Groundwater supplies ten to fifteen percent of the district’s water demand. Cal Water monitors the groundwater level of its wells. Figure 3 shows the average ground water level for the South San Francisco District. The water level has remained relative constant since 1990 due to the area receiving average to above average rainfall and that the wells have been operating at less than 60% of total capacity. The water levels have been rising since 2003 since 16 the wells have been placed off-line as part of a SFPUC program to demonstrate the feasibility of a conjunctive use program.SFPUC proposes to install wells in the Westside Basin, then have Cal Water, Daly City and San Bruno not pump their wells during periods of above average precipitation and thereby “bank” the groundwater or increase the quantity of groundwater basin storage. During dry periods when SFPUC anticipates reductions in its deliverable surface supplies, Cal Water, Daly City and San Bruno would pump their normal amounts plus additional amounts of the stored water using the SFPUC installed wells to make up for the surface supply cutback. Agreements to implement this plan, which has been demonstrated to be technically feasible, are currently being negotiated among the parties. Figure 3: South San Francisco District Average Static Groundwater Levels In June 2003, Cal Water entered into an agreement with the SFPUC to conduct a conjunctive use test program its practicality and potential impact on the regional groundwater basin and Lake Merced recovery. The conjunctive use program was for a three year duration. As shown in the above figure, groundwater levels rose in 2004 and 2005. In 2009, Cal Water’s wells were placed back into operation. The South San Francisco District has five active wells with a total design capacity of 955 GPM. If operated full-time, these wells could produce 1.38 mgd (1,540 AFY). This production capacity represents about 17 percent of the annual demand in the district. A maximum of 1,560 AFY was pumped in 1970 and 1983. Over the past two decades, Cal Water’s average groundwater production has been 1,015 AFY, due largely to the availability of SFPUC supplies. Groundwater Basin Boundaries and Hydrology The Westside Basin is the largest groundwater basin in the San Francisco Bay hydrologic region. It is separated from the Lobos Basin to the north by a northwest trending bedrock ridge through 17 the northeastern part of Golden Gate Park. The San Bruno Mountains bound the basin on the east. The San Andreas Fault and Pacific Ocean form its western boundary and its southern limit is defined by bedrock high that separates it from the San Mateo Plain Groundwater Basin. The basin opens to the Pacific Ocean on the northwest and San Francisco Bay on the southeasti. Additional information on the basin is given in the DWR Groundwater Bulletin 118, which is included as Appendix D in the SSF District UWMP. The DWR bulletin provides information on: San Francisco Bay Hydrologic Region Merced Valley (Westside) Basin Santa Clara Sub-basin Groundwater Basin Number: 2-35 Non-adjudicated Status of Basin SFPUC Proposed Conjunctive Use Westside Basin Groundwater Management Plan SFPUC, Cal Water, San Bruno and Daly City for the past 5 years have been working on developing a conjunctive use plan for managing Westside Basin groundwater. Technical and cost studies were conducted along with extensive hydrogeologic modeling to determine the feasibility of using the basin to store water during above normal hydrologic years so that during drought years, the stored water could be extracted to make up for reductions in SFPUC treated surface water supply. Basin storage would be increased due to three utilities (who normally extract groundwater) not pumping during surplus supply years as a result of receiving more SFPUC water. During drought periods, the three utilities would resume pumping and in addition SFPUC would pump the “added” stored groundwater from wells it proposes to construct and operate and either feed this water into its transmission mains or the distribution systems of the three utilities. Considerable effort has been expended in the last three years in working on an agreement among the four parties. This conjunctive use plan would help to reduce the severity of drought supply reductions from SFPUC but would not be adequate since total additional pumped supply among the utilities is considerably less than the proposed combine surface water supply reductions. Recycled Water Recycling of wastewater is evaluated by Cal Water in the SSF UWMP. Use of recycled water for non-potable uses (e.g., landscape irrigation) can reduce demands on SFPUC and groundwater supplies. Currently, no recycled water is used in the SSF District. Following is a summary of the potential for future recycling for non-potable uses. Wastewater Collection The North San Mateo County Sanitation District (NSMCSD) treats wastewater from Cal Water’s South San Francisco service area communities of Broadmoor and portions of Colma. Communities also within the NSMCSD, but not in Cal Water’s service area include Westlake, Westborough County Water District, Daly City, and the San Francisco County Jail. Municipal wastewater is generated in the NSMCSD service area by residential, commercial, and limited industrial sources. NSMCSD owns, operates and maintains its sewer system consisting of gravity sewers and pumping stations. 18 South San Francisco and San Bruno own and operate the South San Francisco Water Quality Control Plant (SSFWQCP). Wastewater from Cal Water’s South San Francisco service area communities of South San Francisco and Colma is treated at the SSFWQCP. Wastewater from San Bruno and a small portion of Daly City is also treated at the SSFWQCP, but these areas are not within Cal Water’s service area. The sewer system includes gravity lines and force mains that combine both wastewater and storm water runoff. The quantity of wastewater generated is proportional to the population and the water use in the service area. For 2008, it is estimated that 3,300 AFY of wastewater flows from Cal Water’s South San Francisco District. It is projected to increase to 3,700 AFY in 2028. Wastewater Treatment in SSF District Area Wastewater at the North San Mateo Wastewater Treatment Plant (NSMWTP) receives secondary treatment. The NSMWTP can not provide tertiary treatment. NSMWTP design treatment capacity is 10.3 MGD average daily flow but currently receives 6.8 MGD from the North San Mateo County Sanitation District service area. Effluent is discharged to an outfall at Thornton Beach via pipeline. Secondary non-public contact treated water is currently recycled from this plant for irrigation of landscaped medians in Westlake. Recycled water from the NSMWTP is not available to the SSF District service area. Wastewater from the South San Francisco Water Quality Control Plant (SSFWQCP) receives secondary treatment with chlorination and de-chlorination before being discharged to the San Francisco Bay. The SSFWQCP also provides de-chlorination for chlorinated effluent for Burlingame, Millbrae, and San Francisco International Airport. The SSFWQCP has capacity to treat 13 MGD average daily flow (instantaneous peak wet weather flow capacity of 30 mgd) and currently receives 10 MGD from the SSFWQCP service area. The SSFWQCP does not provide recycled water. An assessment of using recycled water from this plant was made by the firm CDM in preparing the Cal Water’s Water Supply and Facilities Master Plan for the SSF District and although it was concluded to not be feasible presently, it was recommended that recycling should be re-evaluated in the future. Potential Water Recycling in District South San Francisco has conducted studies to assess the feasibility of developing a recycled water program and is continuing with further investigations to determine capital and operations and maintenance costs associated with various stages of implementation of a water recycling program as well as environmental, institutional, regulatory, and financial issues that must be addressed. NSMCWTP staff has worked on upgrading its treatment facilities to meet Title 22 requirements, i.e., tertiary treatment. Some process improvements have been made. Planned uses for recycled water include irrigation of three golf courses adjacent to the treatment plant and irrigation of local median strips and athletic fields. However, theses golf courses currently use groundwater for irrigation. The golf courses and median strips are not within Cal Water’s SSF district service area. In addition, Cal Water’s service areas in Broadmoor and Colma are residential communities with no current use for recycled water. It is hoped that potential customers will be served with recycled water from the North San Mateo Wastewater Treatment Plant in the future, but none of these potential customers are within Cal Water’s service area. 19 Current projected recycled water demand for Cal Water’s service area, which is served by NSMWTP through 2030 is 0 acre-feet per year. Cal Water will continue to participate in planning for future recycled water project(s) with South San Francisco, San Bruno and SFPUC and consider supporting a joint feasibility study with Daly City to investigate supplying recycled water to Colma cemeteries. The SSFWQCP will be at capacity in approximately 5 years and any available space will be used to increase capacity. Under current conditions the SSFWQCP does not have plans to provide recycled water at any time in the near future. Desalinated Water Desalination of either brackish groundwater or San Francisco Bay water has been assessed by Cal Water in its December 2010 Integrated Long Term Supply Plan (ILTSP) for its three peninsula districts that are served by the San Francisco Public Utility Commission (SFPUC). It was found to be potentially feasible and the plan recommends proceeding in the near future with more detailed investigations to further develop technical, cost, environmental and permitting information. In addition to technical and cost feasibility studies, desalination treatment facilities require environmental studies and close coordination with local and state agencies. Conservatively, eight years of lead-time may be required from feasibility and environmental studies and permitting to initiation of construction. Currently, there are no desalinated water supplies available. The following is information is summarized from Cal Water’s December 2010 Integrated Long Term Supply Plan for the three peninsula districts prepared by the engineering firm CDM. Cal Water Peninsula Districts (3) Desalination Alternatives Location Varies: From SSF to Redwood City -See Figure Intakes Vertical wells (brackish groundwater) Slant wells (seawater) Open water (seawater) Brine Disposal Joint use WWTP outfall New outfall Cargill brine line 20 Cal Water Peninsula Districts (3) DesalinationAlternatives (continued) Small capacity plants Sub-surface intake 1 to 10 mgd Simplify permitting Lower costs and environmental risk Large capacity plants 10 to 20 mgd Open water intake Greater costs and risks Factors Influencing Desalination Feasibility Yield Extraction amounts Brine disposal quantities -Hydraulics and NPDES permitting Operations Considerations Continuous vs intermittent production Degree of facilities redundancy Staffing Approvals EIR –adequate water conservation and recycling? Permitting 21 Potential Desalination Plant Intake Locations, and Brine Discharge Locations 22 Possible Locations for Desalination Treatment Facilities in SSF District Water Transfer Agreements and Exchanges As indicated in the ILTSP for the three peninsula districts, Cal Water is pursuing water transfer agreements with water agencies in the Central Valley (CV). With the right source and water agency, water could be acquired by Cal Water and transferred to the Tuolumne River Basin for subsequent SFPUC conveyance, treatment and delivery to Cal Water’s three peninsula districts. Another option is to acquire water from an agency that is a state water contractor and negotiate a transfer with Department of Water Resources (DWR) for delivery to the Santa Clara Valley Water District (SCVWD) via the State Water Project (SWP) to the South Bay Aqueduct for transmission, treatment and transfer to Cal Water’s Los Altos Suburban District (LAS), which is served by SCVWD. Cal Water could negotiate an exchange with another agency that is served by both SFPUC and SCVWD so that instead of taking SFPUC water, the agency received SCVWD water that is not used by Cal Water. This would help increase groundwater storage in LAS since less groundwater would be pumped under this plan. Another option is for Cal Water to transfer acquired CV supply treated by SCVWD to its Bear Gulch District through a newly constructed pump station and pipeline. Initial transfers amounts of approximately 4,000 to 6,000 AFY would increase SSF district supply since SFPUC supply to the three peninsula districts is treated as a whole, i.e., Cal Water can decide which district receives the added supply credit. Cal Water envisions that it would take 3 to 5 years to develop a water supply transfer agreement and address all planning, environmental and engineering requirements. Purchased Water As previously indicated, Cal Water serves the South San Francisco District, Mid- Peninsula District (San Mateo and San Carlos), and Bear Gulch District (Atherton, Portola Valley, 23 Woodside, portions of Menlo Park, and adjacent unincorporated portions of San Mateo County including; West Menlo Park, Ladera, North Fair Oaks, and Menlo Oaks). The major supply for three districts is purchased treated water from SFPUC. The Water Supply Agreement between The City and County of San Francisco and Wholesale Customers in Alameda County, San Mateo County and Santa Clara County (WSA), provides for a 206,106 AFY (184 mgd annual average basis), Supply Guarantee to SFPUC’s wholesale customers collectively. This allocation was reached through negotiation in the early 1990s between the SFPUC and Bay Area Water Users Association (BAWUA), the predecessor organization to BAWSCA. Cal Water’s Individual Supply Guarantee (ISG) for the three districts is 39,966 AFY (35.68 mgd). The SFPUC can meet the water demands of its retail and wholesale customers in wet and normal years, however; the SFWSA allows the SFPUC to reduce water deliveries during droughts, emergencies, and for scheduled maintenance activities. The SFWSA between the SFPUC and its wholesale customers adopted in July 2009 provides that the SFPUC will determines the available water supply in drought years and call for reductions to deal with these shortages of up to 20% on an average, system-wide basis. The table below taken from the SFWSA identifies various potential levels of supply reductions in terms of share of available supply, percent of available supply and resulting percent reduction faced for SFPUC retail and wholesale customers. A reduction in available supply of greater than 20% would require special negotiation between SFPUC and BAWSCA. SFWSA Interim Water Shortage Allocation Plan - Tier 1 Reduction Rates Level of System Wide Reduction 0% 5% or less 6% to 10% 11 % to 15% 16% to 20% Percent Reduction (1) 0% 5% 10% 15% 20% Interim Supply Limitation (ISL) 265.0 251.8 238.5 225.3 212.0 Wholesale Customers Share 69.4%64.5%64.0%63.0% 62.5% Share of Available Water(1) SFPUC Share 30.6%35.5%36.0%37.0% 37.5% Wholesale Customers 184.0 162.4 152.6 141.9 132.5 Quantity of Available Water ( mgd ) SFPUC Retail 81.0 89.4 85.9 83.3 79.5 Wholesale Customers 0.0%-11.8%-17.0%-22.9% -28.0% Percent Reduction from Normal Supply SFPUC Retail 0.0%10.3%6.0%2.9% -1.9% In the SFWSA, SFPUC has the authority to determine that during a moderate drought (taken here as a “dry year”) resulting in an available supply reduction of 5% to 10%, it may cut back deliveries to the wholesale customers of 17% of the wholesale customers collective Individual Supply Guarantee (ISG). Likewise during a severe drought (taken here as “multiple dry years”) resulting in an available supply reduction of 11% to 20%, it may cut back deliveries by 28% of the wholesale customers collective ISG amount. 24 SFPUC in cooperation with the members of the Bay Area Water Supply and Conservation Agency (BAWSCA) prepared a Water Supply and Facilities Master Plan for the service area, which lead to the Water Supply Improvement Program (WSIP). As a BAWSCA member, Cal Water reviewed 2030 demand projections prepared by BAWSCA and determined the most likely purchase amounts for that time period. Cal Water has and continues to work with SFPUC and BAWSCA in developing SFPUC’s Capital Improvement Plan. This has included development of demand projections. Cal Water has reviewed and concurs with SFPUC and BAWSCA’s projected service area population, customer water demand, conservation program levels and estimates of supply purchases from the SFPUC. Their projections are consistent with and are within the range of values contained in Cal Water’s SSF Urban Water Management Plan; both the currently approved and draft updated versions. Copies of these concurrence statements and the associated values are included in Appendix K of the SSF UWMP. Because SFPUC will not increase the available supply to its wholesale water customers, at least in the foreseeable future, Cal Water developed an Integrated Long Term Supply Plan for its three peninsula districts to meet future growth and droughts. This plan calls for enhanced conservation as mandated by SB7, development of water supply transfers, and investigation of the feasibility of desalinization. During normal or above normal hydrologic conditions and based on water demand forecasts included in the ILTWSP prepared by CDM, Cal Water’s three districts as a whole do not need additional supplies through 2030. Under normal hydrologic conditions with the SFPUC ISG and 90% of local supply available, Cal Water can meet its projected demand in 2030 for all three peninsula districts. Table 6 shows anticipated supplies versus demand for all three Cal Water peninsula districts under normal hydrologic conditions.

There are various combinations of supplemental supplies and levels of increased conservation being assessed by Cal Water under the supply reductions planned by SFPUC during drought. Cal Water’s experience shows its can achieve an additional 5% - 10% demand reduction through voluntary measures during drought. An additional 5% of demand reduction can be readily achieved through mandatory rationing resulting in a total of 15% additional demand reduction. The amount of additional supplies that need to be developed and provided by Cal Water depends on the drought level and effectiveness of additional conservation and rationing measures. The range of additional supplies required under the two drought conditions (moderate and severe) is presented in Table 7. The demand, supply and reductions quantities included in Table 6 above and Table 7 below; and also discussed below are from early draft updates of the UWMP and from BAWSCA’s DRIP. These are reasonably similar but not exactly the same as those included in the versions under consideration for adoption. Table 7: Multiple Dry Year Conditions (Moderate and Severe Drought) Cal Water's 3 Peninsula Districts (mgd) Year Demand with Conservat ion Local Supply 17% Reduction of SFPUC Supply 28% Reduction of SFPUC Supply 15% Drought Driven Demand Reductio n Moderate Drought: Net Supply Severe Drought: Net Supply 201037.661.1029.6125.695.65-1.30-5.22 201536.271.1029.6125.695.44-0.12-4.04 202034.381.1029.6125.695.161.49-2.43 202535.091.1029.6125.695.260.89-3.04 203035.821.1029.6125.695.370.27-3.66 In 2010, for a 17% SFPUC supply reduction accompanied by an additional 15% drought driven demand reduction, the additional supply required is 1.3 mgd (1,457 AFY). In 2010, for a 28% SFPUC supply reduction accompanied by an additional 15% drought driven demand reduction, the additional supply required is 5.22 mgd (5,852 AFY). In 2020, because Cal Water will have progressively implemented permanent demand reductions as a result of its enhanced conservation program in compliance with SB 7, no additional supply is required for a 17% reduction in SFPUC supply if there is an additional 15% drought driven demand reduction. There would be a net surplus of 1.49 mgd in this case. In 2020, even with the benefits of an enhanced conservation program in compliance with SB 7, and a 15% drought driven demand reduction, the 28% reduction in SFPUC supply results in a shortfall of supply of 2.43 mgd (2,724 AFY). 26 In 2030, additional supply requirement is projected to increase again since there is no assumed further increase in water conservation demand reduction. For the 17% SFPUC supply reduction with 15% additional drought driven demand reduction, there is a slight supply surplus of 0.27 mgd (303 AFY). In 2030, for a 28% SFPUC supply reduction with 15% additional drought driven demand reduction, additional supply needed is 3.66 mgd (4,103 AFY). As indicated in Table 7, projected increases in water conservation reduce supply needs between 2010 and 2030 by 1.84 mgd (2,062 AFY). The above SFPUC supply analysis is based on no additional reductions in supply from SFPUC. However, that is not certain since in October 2010 SFPUC advised Cal Water and BAWSCA that newly agreed to fishery flow releases on Alameda Creek (Calaveras Reservoir) and San Mateo Creek (Crystal Springs Reservoir) will reduce the limited SFPUC annual average local supply by an additional 7.4 mgd. This reduction in local supply could have a more significant effect on Cal Water due to the Raker Act which limits Cal Water to local SFPUC supply sources rather than the much larger supply source from the Tuolumne River basin. The potential additional reduction in supply has not been established by the SFPUC. However, it could result in additional SFPUC supply reductions during drought periods and possibly during normal hydrologic conditions. Water Quality Historically and presently, Cal water meets all state and federal water quality regulations. The well field in the SSF District has treatment facilities for removal of iron and manganese ions and blending for nitrates and Volatile Organic Compounds (VOCs). The water purchased from SFPUC has trihalomethane concentrations that can exceed California drinking water standards. To reduce this problem, SFPUC has converted its disinfection system from free chlorine to chloramines. Cal Water has also installed ammonia chemical feed equipment at its well field to accomplish chloramination of well water. The well field is permitted for use only when pumped groundwater is blended with SFPUC water. The need for back-up supply is the most important challenge with respect to water quality. Water Supply Projects Cal Water will continue its annual main replacement program to upgrade and improve the distribution system of the SSF District. Storage facilities and new booster pumps will be added as needed to meet the average day and maximum day requirements. Because growth potential is limited, no major new facilities are currently planned, only replacement of existing facilities. Future capital expenditures are planned for drilling and developing new wells to replace aging wells currently in operation, which will increase system reliability and allow Cal Water to pump its full share of sustainable extracted groundwater from the Westside basin, which Cal Water estimates at 1,500 AFY. Cal Water’s SSF Water Supply and Facilities Master Plan includes a capital improvements plan and schedule. 27 Water Demand Management Water conservation reduces water supply needs. In addition to Cal Water’sexisting conservation programs, Cal Water received approval from the California Public Utilities Commission (CPUC) in December 2010 for expanded SB7 driven programs for 2011 – 2013. This approval increases conservation expenditures in some of its districts by over 700% annually. Expanded conservation programs will enable Cal Water to achieve greater per capita water use reductions as required by SB7. Based on Cal Water’s analysis of SB7 requirements, SSF District potable water use is projected to be reduced by 1,393 AF in 2030 compared to the forecasted demand without SB 7 (Table 4). Cal Water is also implementing enhanced water conservation programs in response to the requirements of SB7 in its Bayshore (San Mateo and San Carlos) District and Bear Gulch (part of Menlo Park, Atherton, Woodside, Portola Valley and other areas) District during this period with the same goal to achieve substantial reductions in water demand by 2020. During severe drought periods it is likely that further reductions in demand beyond those projected from implementation of the SB7 conservation program will be required. This is shown in Table 7 as a 15% drought driven demand reduction With respect to in-place conservation programs, Cal Water is a member of the California Urban Water Conservation Council (CUWCC). The CUWCC was created to increase efficient water use statewide through partnerships among urban water agencies, public interest organizations, and private entities. The Council's goal is to integrate urban water conservation Best Management Practices (BMP) into the planning and management of California's water resources. Implementation of water conservation BMPs will help limit water demand from customers within the SSF District’s service area and reduce water supply requirements. Cal Water submits reports to the CUWCC every two years describing implementation of its conservation best management practices (BMP). The Department of Water Resources (DWR), water utilities, environmental organizations and other interested groups collaboratively developed urban BMPs for conserving water and signed a Memorandum of Understanding Regarding Urban Water Conservation in California (MOU) (amended March 9, 2005) to implement these BMPs. The MOU is administered by the CUWCC. As a signatory of the MOU, Cal Water has agreed to implement the BMPs as defined in Exhibit 1 of the MOU that are cost beneficial and complete implementation in accordance with the schedule assigned to each BMP. Table 8 presents the BMPs as defined by the MOU. 28 Table 8: Existing Water Conservation Best Management Practices No. BMP Name 1 Water survey programs for single-family residential and multi-family residential connections 2 Residential plumbing retrofit 3 System water audits, leak detection and repair 4 Metering with commodity rates for all new connections and retrofit of existing connections 5 Large landscape conservation programs and incentives 6 High-efficiency washing machine rebate programs 7 Public information programs 8 School education programs 9 Conservation programs for commercial, industrial, and institutional accounts 10 Wholesale agency assistance programs 11 Conservation pricing 12 Conservation coordinator 13 Water waste prohibition 14 Residential ULFT replacement programs Water Demand Reduction Should there be periods of anticipated water supply shortages, Cal Water has in place plans and measures for further reducing customer water demand. This includes if necessary mandatory reductions, rationing, and penalties. As shown in Table 9, Cal Water has a four-stage water demand reduction plan comprised of voluntary and mandatory stages. Approval from the CPUC must be obtained prior to implementation of mandatory restrictions. Table 9: SSF District Water Demand Reduction Plan Supply Shortage Stage Demand Reduction Goal Type of Program Minimum 5 - 10% Stage 1 10% reduction Voluntary Moderate 10 - 20% Stage 2 20% reduction Voluntary or Mandatory* Severe 20 - 35% Stage 3 35% reduction Mandatory* Critical 35 - 50% Stage 4 50% reduction Mandatory* * Mandatory = Allocations 29 The following summarizes the actions to be taken during periods when demand reduction is required: Stage 1 Public information campaign consisting of distribution of literature, speaking engagements, monthly bill inserts, and conservation messages printed in local newspapers (ongoing) Educational programs in area schools (ongoing) Stage 2 More aggressive public information and education programs Requests to consumers to reduce voluntarily water use by 10 to 20 percent or mandatory reductions will be implemented Prior to implementation of mandatory reductions, obtain approval from CPUC Lobby for passage of drought ordinances by appropriate governmental agencies Stage 3 Implement mandatory reductions after receiving approval from CPUC Maintain rigorous public information campaign explaining water shortage conditions. Water use restrictions go into effect; prohibited uses explicitly defined Limiting landscape irrigation by restricting hours of the day and or days of the week during which water for irrigation can be used Monitor production weekly for compliance with necessary reductions Installation of flow restrictors on the service lines of customers who consistently violate water use restrictions Stage 4 All of steps taken in prior stages intensified. Discontinuance of water service for customers consistently violating water use restrictions Monitor production daily for compliance with necessary reductions More restrictive conditions or a prohibition of landscape irrigation Section 357 of the Water Code requires that suppliers that are subject to regulation by the CPUC shall secure its approval before imposing water consumption regulations and restrictions required by water shortages. Water Rights to the SSF District Groundwater Supply Cal Water owns the land on which its wells are located in the SSF District. Under state law, the use of percolating groundwater in California is governed by the doctrine of correlative rights and reasonable use, which gives the overlying property owner a common right to reasonable, beneficial use of the basin supply on the overlying land. The Westside Basin is an unadjudicated groundwater basin. Design, Construction and Operation of OPSP Water Supply Facilities Cal Water will provide the developer of the private development portion of the OPSP with a will serve letter indicating its intention to serve as the water utility for providing water service. A 30 complete water system includes distribution system, meters, etc. As planning and design proceed further, Cal Water anticipates working closely with the developer, its engineer, the City of South San Francisco, CA Dept of Public Health and any other agencies that may be involved with the approval of required water supply facilities. Cal Water will review all proposed design drawings and specifications for compliance with state and Cal Water’s standards with respect to pipe sizes, valves, materials, etc. and connection to its existing system. Cal Water’s SSF District, supported by its engineering, water quality and customer service staff in San Jose, will be responsible for providing ongoing local operations and maintenance services of the water system. SB 610 Section 10910 Paragraph (d)(2) requires identification of existing water supply entitlements, water rights, or water service contracts held by the public water system shall be demonstrated by providing information related to all of the following: (A)Written contracts or proof of entitlement to an identified water supply. Proof of entitlement to use of the wells cited as a major supply source to the District is demonstrated by Cal Water’s ownership of the property and the wells and its legal right to use the underlying percolated waters. Proof of entitlement to the use of SFPUC treated water are provided in the contracts cited in this document between Cal Water and SFPUC and are available for review. (B)Copies of a capital outlay program for financing the delivery of a water supply system that has been adopted by the public water system. Capital costs for design and construction of the water distribution system within the development site are the responsibility of the developer. The developer will also be responsible for per lot assessment fees in accordance with California Public Utility Commission (CPUC) rules to cover the cost of the water supply. Cal Water’s SSF District capital improvement program is separate from and does not include any of the costs associated with the design and construction of the water system for or within the OPSP area. However, upon legal transfer of the completed water system external to the development site to Cal Water by the developer, the water system will be incorporated into Cal Water’s capital improvement and maintenance programs. The SSF District Water Supply and Facilities Master Plan provides specific recommendations for water system facility or capital improvements to the year 2030. It is Cal Water’s intention to update this plan and recommended capital improvements every five years. Federal, state, and local permits for construction of necessary infrastructure associated with delivering the water supply. For any distribution system improvements, the developer will be required to obtain the necessary building permits from the City of South San Francisco. 31 It does not appear that additional storage facilities are needed for this project. Were a storage tank required, Cal Water would be responsible for its design and construction and for obtaining a conditional use permit and building permit. The developer would be responsible for direct reimbursement of those costs to Cal Water. Cal Water is highly experienced in preparing applications and obtaining the necessary permits that are needed in order to proceed with design, construction, startup and operation of water distribution facilities. Cal Water is familiar with approvals it must obtain from the City of South San Francisco and California Dept of Public Health. Comparison of Supply and Demand Demand and Supply Comparison for a Normal Hydrologic Year: Table 6 presents a supply and demand comparison for normal hydrologic conditions for all three Cal Water peninsula districts that are served by SFPUC. It demonstrates that the combination of existing local and purchased supplies are adequate to meet forecasted demands for the OPSP and those associated with existing Cal Water customers and all other new developments in the SSF District. Active wells in the SSF District have total capacity of 1,540 AFY. The SSF District had for several years not pumped any groundwater due to Cal Water’s participation in a demonstration study for a proposed SFPUC in-lieu groundwater storage program. Hence, Table 5, groundwater production in 2005 is 0 AFY. The total supply capacity of SSF wells is expected to increase slightly over time as new wells are installed. As illustrated in Table 5, the future production of groundwater from 2010 to 2030 will be held at 1500 AFY. Based on historical data, future demand projections, contracted treated water deliveries from SFPUC under normal hydrologic conditions and the mandated SB7 conservation savings are expected to generate a surplus SFPUC supply during the period 2015 to 2030 of between 2.0 and 3.84 MGD. Therefore, Cal Water believes under normal hydrologic conditions supplies will be adequate to meet the projected 20 year demand for the SSF District including OPSP with its forecasted increase of SFPUC supplies, groundwater supplies, increased demand management or conservation. Other supply plan objectives include water transfers and/or desalination of local waters. Demand and Supply Comparison for a Single Dry Year: For a single dry year based on previous experience, Cal Water expects no reduction in SFPUC supplied water. Therefore the total supply available to the three peninsula districts and the SSF district during a single dry year is considered to be the same as for a normal hydrologic year. The same assumption applies to the amount of groundwater that will be pumped, even though it is Cal Water’s intention to develop sufficient redundant capacity to extract more water than its average annual pumpage. During a single dry year local surface runoff that feeds the Bear Gulch Reservoir in Cal Water’s Bear Gulch District may be reduced. While a single dry year may trigger increased water conservation measures in Cal Water’s upgraded conservation program, as shown in Table 6, demand has not been further reduced to reflect those likely changes. 32 Demand and Supply Comparison for Multiple Dry Years: As shown in Table 7, SFPUC has indicated that depending on the degree of drought during a multiple dry year period, it proposes to reduce supply to its wholesale customers by 17% for a moderate drought and 28% for a severe drought. During the first year, it is expected that demand and supply might be as indicated in Table 6. In the second and third years, it is expected that Cal Water would implement additional conservation measures to reduce demand by 15% because of SFPUC’s probable imposition of a 17% supply reduction requirement. As shown, this would result in a near adequate supply for all three Cal Water peninsula districts in 2015 (minus 120,000 gpd) and a positive supply condition from 2015 to 2030. Should SFPUC reduce supply by 28% due to a more severe drought condition and Cal Water has not yet been able to complete development of additional supplies as described previously in this WSA, Cal Water would have a net shortage of supply on average of around 4.0 mgd (4,484 AFY). Under these circumstances, Cal Water might have to implement Stage 3 mandatory reductions to achieve another 11% of drought driven demand reduction (i.e., 4.0 mgd) for a total of 26% drought driven demand reduction. It is assumed here that Westside Basin groundwater supplies would continue to be pumped at current rates even though that would result in a reduction in basin storage and a lowering of groundwater levels. It is also assumed that the local runoff supply that feeds the Bear Gulch Reservoir in Cal Water’s Bear Gulch District would under these circumstances be zero. Water Supply Assessment Conclusion Based on: 1.Current Westside Basin groundwater supplies and Cal Water’s current and projected groundwater production rates from its active wells, 2.Generally adequate long-term normal hydrologic supplies provided by the SFPUC, but recent significant proposed reductions in supply during moderate and severe droughts, 3.An enhanced demand reduction program to meet requirements of state law SB7 to achieve 20% reduction in supply by 2020, 4.Future Cal Water plans to develop additional supply sources including transfers of supplies from outside the peninsula area and development of local desalination facilities, 5.The prospect of longer term additional local supplies being obtained from SFPUC’s proposed conjunctive use program for the Westside Basin, 6.Possible recycled water projects being developed collaboratively among local wastewater and water utilities in the SSF District area, 7.Cal Water’s ability to achieve additional drought driven reductions in demand (15% to 26%) during moderate and severe droughts (multiple dry years) through its established in-place water rationing programs, 8.Historical performance which demonstrates Cal Water’s ability to both increase supply sources and effectively achieve demand reductions if required, Cal Water’s concludes that for the next 20 years, its SSF District will be able to provide adequate water supplies to meet its existing and projected customer demands which includes all four 33 phases of the proposed Oyster Point Specific Plan for normal, single dry year and multiple dry year conditions. Cal Water is currently engaged in planning, designing and constructing new water supply projects including wells, groundwater treatment facilities and related distribution and storage facilities so as to increase supply capacity ahead of projected demand growth. The plan is to provide adequate supply capacity to accommodate growth even during dry weather periods that result in reductions in SFPUC surface water deliveries. Implementation Cal Water will provide the developer of OPSP developer with a will serve letter indicating its intention to provide water service after the proposed development is approved by the City of South San Francisco. Cal Water will insure that the required water facilities are designed consistent with the proposed development plan and will coordinate with the developer, its engineer, the City of South San Francisco, and the California Dept of Public Health in the design, construction and operation of the proposed water distribution system. Cal Water will insure compliance with state and city standards with respect to pipe sizes, fire flows, equipment, materials, valves, appurtenances and connection to its system. Cal Water’s SSF District supported by its engineering, water quality and customers service staff in San Jose, will be responsible for providing ongoing operations and maintenance services for the constructed water facilities.

The Project location is illustrated in Figure 1. The Project is under the planning jurisdiction of theSouth San Francisco East of 101 Planning Area,which consists primarily ofindustrial and bio-technological offices. The current project site encompasses a varietyof uses, including marina services buildings, the Oyster Point Business Park, the Oyster Point Inn andadjacent office buildings, and a bait and tackle shop. Carollo Engineers Inc.was contracted by Lamphier-Gregoryto determine the impacts of the project onexisting utilities within the City, including the water system, wastewater collection system, wastewater treatment, and stormwater system.This study will be included inthe Environmental Impact Report (EIR) for the Project. 2.0PROJECTDESCRIPTION According to the Draft Oyster Point Master Plan and Design Guidelines Report (Oyster Point Master Plan, Perkins and Will, September 2009) the Project will be locatedonapproximately 81acres of privately and publicly held lands.Private properties will beredeveloped asanoffice, researchand development business park, andauxiliary commercial and retail properties. Redevelopment plans for publicallyheldproperties includeanew hotel, recreational fields,and open space(OysterPoint Park).Infrastructure improvements required for the new planinclude realigning Marina Boulevardand replacing the existing utilities. The Project is planned for four phases,plus a hotelplanned for the more distant future.The projectsiteis shownin Figure 2. The four phases will developovertwo million square feet of office and research and development space. The planned floor space needs for the four phases are summarized in Table 1. Per direction from City staff, a 40/60 split between office and research and development(R&D)was assumed. The EIR will address the impacts from the Project on a project level and a programmatic level. The project level evaluation is based on the development of Phase I, where the programmatic evaluation considers the impacts from the total Project. The development of Phase I includes 518,000 square feet of office, R&D, and auxiliary commercial space.

Water demand projections prepared for the City’s East of Highway 101Sewer System Master Planin 2007were used as the basis for projecting water demand for the Project.Thewater demands were based on projections prepared by EIP and Associates for the Genentech Research and Development Overlay District Water Supply Assessment in 2006 (Genentech WSA). The water demand factors used for this assessment are shown in Table 2.

The Genentech/WSA water demand factors wereused to project water demands for the Project. Office/R&D land use types were assumed to develop as40 percentofficespaceand 60 percent R&Dspace.Table3 summarizes the projected water demands.The estimated average daily demand (ADD) for the Project totals approximately 0.4 mgd. Based on peaking factors in California Water Service Company’s South San Francisco District Urban Water Management Plan, a peaking factor of 1.57 was applied to the ADD to determine the projected Maximum Day Demand.Using this factor, the maximum daywater demand for the Project is estimated to be 0.63mgd. The estimated average daily water demand for Phase I totals approximately 0.08 mgd, while the maximum day water demand is estimated to reach 0.13mgd. 2.2 WASTEWATER FLOWS The 2007 Sewer Master Plan Updateestimatedwastewaterflows for the East of 101 area at 90 percent of the water demands. Based on this ratio, the average daily wastewaterflow for the total Project is estimated at 0.36 mgd.The average daily wastewater flow from Phase I is estimated at 0.072 mgd. The hydraulic model of the sewer collection system developed for the East of Highway 101 Sewer Master PlanUpdate was used to assess the impacts of wastewater flows from the Project. The model simulateshourlydry weatherflow variations inthe sewers,andpeak flows during wet weather. High flows during wet weather come from extraneous flows (groundwater, stormwater, also known as infiltration and inflow)that enter the sewer through pipe defects such as offsetjoints or cracks.

Water service is provided by the California Water Service Company (CWSC). 4.1Water System The water system in the East of Highway 101 areais owned and operated by the California Water Service Company (CWSC). CWSC’ssupply source consists of eight groundwater wells andsurface waterwholesaled bythe San Francisco Public Utilities Commission (SFPUC). CWSC is a member of the Bay Area Water Supply and Conservation Agency (BAWSCA).CWSC serves three districtson the San Francisco Peninsula:Bear Gulch, Mid Peninsula, and, South San. FINAL –January 20118 pw://Carollo/Documents/Client/CA/South SF/8543A00/Deliverables/OPSB_Study.doc (Draft) 4.1.1 WaterDistribution System The existing water distribution system for the Project area is illustrated in Figure 3.The area is supplied from a16-inch diameter water main in Oyster Point Boulevard.The eastern portion of the system that serves the Marina consists of 12-inch diameter water mains in Marina Boulevard and 8-inch diameter mains along the north side of the waterfront. A 12-inch diameter main runs north along Oyster Point Boulevardto serve businesses in the Oyster Point Business Park. 4.1.2 WaterSupply Sources CWSC is a wholesale customer of SFPUC. According to the Bay Area Waster Supply and Conservation Agency (BAWSCA)Long Term Reliable Water Supply Strategy Phase I Scoping Report,CWSC is guaranteed an allocation from SFPUC of 35.68 mgd during normal years. CWSC also relies on groundwater wells within the Westside Groundwater Basin and surface water from the Bear Gulch Reservoirto supplement the water they are allocated fromSFPUC.The groundwater and surface water supplies account for 1.37 mgd each, for a total of 2.74 mgd. The combination of SFPUC allocations and local sources provides a maximumsupply of 38.68 mgd during normal non-drought conditions(35.68 mgd from SFPUC plus 2.74 from groundwater and surface water). CWSC distributes the total supply among the three districtson the San Francisco peninsula, and can apportion water among the districts as required to meet demands. 4.2Wastewater Collection System The City’s wastewater collection system in the East of Highway 101 area consists of approximately 13 miles of 6-inch through 30-inch diameter sewers(see Figure 4). The system consists of a series of gravity sewersand pump stations that convey flow to the main pump station (Pump Station No4);Pump Station No. 7conveys a small portion of the East of 101 area to the WQCP as well).The portion of the City’s collection system that serves the Oyster Point development area includes the Oyster Point Subtrunk, Pump Station No.2, the Gateway Trunk, the Harbor Way Trunk, Pump Station No 4,and the Pump station No. 4 Forcemain. The collection system components serving Oyster Point are described below. 4.2.1 Trunk Lines The Harbor Trunk begins at Pump Station No. 4 and continues northward (upstream) along Harbor Way with a 30-inch trunk sewer, then a 27-inch pipeto East Grand Avenue. This is the largest interceptor in the system that conveys flow from the system north of Mitchell and East Harris Avenues.

It continues east (upstream) to the intersection of Gull Road and Oyster Point Boulevard. The trunk becomes an 8-inch diameter sewer between Eccles Avenue and Veterans Boulevard. 4.2.1 Pump Stations Pump Stations No. 2 and No. 4 convey flow from the Oyster Point area. Pump Station No. 2 is located at the intersection of Gateway Boulevard and Oyster Point Boulevard. It consists of two 20 horsepower pumps each with a capacity of 1,000 gallons per minute (gpm). The firm and total capacity is 1.44 and 2.88 million gallons per day (mgd) respectively. Pump Station No. 2 dischargesinto a 843-foot long 10-inch diameter forcemain. Pump Station No. 4 is located at the intersection of Harbor Way and Mitchell Avenue. Pump Station No. 4 was upgraded by installing four new 70 Hp motors and four new 3,000 gpm pumps. The new firm and total capacity are 12.9 mgd and 17.3 mgd respectively. Pump Station No. 4 is the largest pump station in the system and discharges flow to a 2,814 linear foot 21-inch diameter forcemain that discharges at the headworks of the WQCP. 4.2.2 Wastewater Treatment System–Water Quality Control Plant Sincethe first construction in 1945, thejointly owned South San Francisco and San Bruno WQCPPlant has undergone many upgrades and expansions. The last major expansion occurred in 2000. Currently, the plant processes include preliminary treatment (headworks), primary clarifiers, secondary treatment utilizing an air activated sludge process, effluent disinfection and dechlorination. An overview of the existing facilities is provided in Figure5. The treated effluent is discharged to the San Francisco Bayin a 54-inch diameter submarine gravity outfall. The most recent WQCP upgrade project was completed in 2005. The project included improvements to accommodate peak wet weather flows, includinga 7-million gallon (MG) secondary effluent storage basin, an expansion of the influent pump station, and an effluent pump station. The WQCP currently has a average dry weather flow capacity of 13 mgd and a wet weather flow capacity of 62 mgd.The City is implementing a new capital improvementplan (CIP) to increase wet weather flow capacity, add reliability improvements, and add green energy facilities. The CIP will be implemented in several phases over the next 10 years.

Thestorm watersystem consists of a variety of disconnected drainage systems, including surface street drainage, and underground storm drainsthat drain tonumerous outfalls that discharge to the San Francisco Bay (Bay)along the north, west, and eastern sides of Oyster Point. Stormwater flow from theoutfallsis not treated. The National Pollutant Discharge Elimination System Municipal Regional Stormwater Permit(Provision C3) for South San Francisco, requires that best management practices (BMPs) and low impact development (LID) practices be implemented as part of the redevelopment of the Project area. The quantity of storm runoff during rainfall events is affected by the percentage of impervious surfaces versus pervious surfaces. Impervious surfaces, such as pavement and buildings, cause more runoff than pervious surfaces such as landscaped areas. Thearea of impervious surfacesfor the existing development was estimated using aerial imagery and geographical information system (GIS) software. Figure 7 illustrates the pervious and impervious areas prior to development of the Project. The existing impervious areacovers approximately 45 of the total 80 acres, or 57 percent of the total area. 5.0PROPOSED CHANGES TO UTILITIES The redevelopment of Oyster Point includes a realignment of the eastern portion of Oyster Point Boulevard and Marina Boulevard. As a result,many of the existing utilities will be abandoned and replaced. This section describes the changes to the existing utilities,the construction sequence for Phase I, and the initial infrastructure developmentproposed by the Project developers. 5.1Initial Infrastructure and Phase I Construction The Oyster Point Master Plan describes the proposed construction sequence and the initial infrastructure development that will occur before the construction of Phase I. According to the Master Plan,the developers propose to: x Demolish the Oyster Point Inn, adjacent office buildings, the Oyster Point Marina entry kiosk and the marina service building, x Construct the reconfigured Oyster Point and Marina Boulevard intersection and install the proposed utilities (described in the sections to follow) in Oyster Point and Marina Boulevards, x Complete site work to include, landfill cover modifications, grading for Phase I of the office and R&D development, the open space, and the future hotel site.

The new on-site distribution system will consist of new 12-inch diameter water mainsrouted along the realigned Marina Boulevard and Oyster Point Boulevard.The new mains will branch from the existing 16-inch water main in Oyster Point Boulevardandconnect with the existing 8-inch water main on the marina waterfrontto form distribution loops around the marinafacilities.The new 12-inch diameter loop system is subject to review by CWSC. The analysis in this study will only asses impacts to existing 16-inch diameter water main that will serve the Project area. 5.3Sewer Collection System Changes To accommodatethe realignment of a portion of Oyster Point Boulevard and Marina Boulevard,the existing sewer systemin this area will need to be revised.Figure 10shows the proposed changes. Pump Station No. 1, located on Oyster PointBoulevard across from north end ofOyster Point Park,will be abandoned. A new pump station will be constructed at north of the intersection of Oyster Point Boulevard and Marina Boulevardandconfigured topump flow through a new 8-inch diameter forcemain. The new pump station will have three dry well submersible pumps equipped with variable frequency drives. The new 8-inch diameter forcemain will discharge flow to the existing 8-inch diameter gravity sewer in Oyster Point Boulevard near the intersection of Oyster Point Boulevard and Gull Road. Future developments on the eastern portion of the Project site, including the proposed future hotel,will drain to new gravity sewers and a new pump station. The pump station will pump flows into a new 6-inch diameter forcemain. The 6-inch forcemain will discharge flow at the same discharge point for Pump Station 1, at a common manhole. 5.4StormwaterSystem Changes As described previously, the existing storm drainage system consists of many disconnected drainage networks. The developer hasproposed to connect to the existing underground drainage network at several locations, and the existing outfalls will continue to be used with modifications to comply with BMPs. According to the Oyster Point Master Plan, stormwater treatment and controls will be designed in conformancewith the use of Best Management Practices (BMPs),and LID practicessuch as vegetated swales, vegetative buffer strips, media filters,and bioretention areasper the requirements of Provision C3 of the City’s NPDES permit.Figure 11illustrates the proposed storm drainage system.

According to CWSC staff, the 16-inch main is adequate to serve the Project with adequate water pressure and flow. Accordingly, no impacts to the water main system areanticipated from the development of Phase I or the total Project. 6.1.2 Water Supply The CWSC purchases the majority of its water supply from the SFPUC. Since 2008 several events have occurred that has affectedthe amount of water available to CWSC. In October 2008, the San Francisco Planning Commission certified the Programmatic Environmental Impact Report (PEIR) for the SFPUC Water SystemImprovement Program (WSIP). The purpose of the WSIP is to repair, replace,and seismically upgrade the SFPUC regional water system, whichis nearing the end of its useful life and is vulnerable to damage during earthquakes. The SFPUC along with the San Francisco Planning Department ultimately decided on a phased WSIP Variant that established, as part of the 2009 Water Supply Agreement between the City and County of San Francisco and Wholesale Customers,the Interim Supply Limitation, whichcapped the amount of water available to wholesale customers (BAWSCA)at 184mgd until the year 2018. In order to limit SFPUC water purchases to 184mgd, BAWSCA developed the Water Conservation Implementation Plan (WCIP, Maddaus Water Management and Brown and Caldwell, September 2009). The WCIP developed projected water demands for BAWSCA member agencies for the year 2018 and 2030. According to the WCIP, BAWSCA members would need to implement water conservation programs in order to conserve up to 10 mgd to keep SFPUC purchases below 184 mgdby 2018. According to CWSC staff, since CWSC is a BAWSCA member agency,the Interim Supply Limitation has an impact on growth as any new demand within CWSC’s SSF District will need to be served through conservation, transfers between CWSC’s three districtsor by developing new supply sources such as groundwater wells, or desalinization.The decision on how to developthe new supply source would be made between the Project developer and CWSC. Groundwater produced in the South San Francisco District comes from the Westside (Merced Valley) Basin. According to CWSC’s South San Francisco District 2006 Urban FINAL –January 201122 pw://Carollo/Documents/Client/CA/South SF/8543A00/Deliverables/OPSB_Study.doc (Draft) Water Management Plan (SSFD UWMP), the Westside Basin is not adjudicated, but CWSC has voluntarily agreed to limit groundwater production to500 million gallons per year or 1.37 mgd.Currently CWSC has seven (7) wells in the South San Francisco District capable of producing over 2.0 mgd. If it is determined that new supply should come from groundwater, CWCS has the ability to develop wells in one of its other districts, such as the Bear Gulch or Mid Peninsula districts, and exchange water with the South San Francisco District. According to CWSC,groundwater sources in the Oyster Pointarea tendto be brackish, and new groundwater wells would most likely need treatment to reduce Iron and manganese, andpossibly nitrates. As described in Section 2.1,average daily water demands for Phase I and thetotalProject are estimated at 0.08 mgd and 0.4 mgdrespectively.According to data provided by the City for the 2007 Master Plan Update,the average daily water demand for the existing users at OysterPoint totalsapproximately 0.02mgdfor the Phase I area and 0.1 for the total Project area. Table 5 summarizes the existing and projected water demands and the net change in water demand for Phase I and the total Project.Phase I and the totalProject areplanned to increase the average daily water demand by approximately 0.06mgd and 0.3 mgd respectively.Theincrease will need to be metbydevelopingnewsupply sources.

FINAL – January 201123 pw://Carollo/Documents/Client/CA/South SF/8543A00/Deliverables/OPSB_Study.doc (Draft) 6.2Recommended WaterSystemImprovements According to Department of Public Health Standards, supply sources should be sized to supplymaximum day demands (MDD) with peak hour demands being met with water from storage tanks and reservoirs. The Project is estimated to increase the average water demand by 0.06mgd for Phase I and 0.3 mgdfor the total Project.Basedona MDD peaking factor of 1.57, the MDD would increase byapproximately 0.09mgdfor Phase I and 0.75 mgdfor the total Project. The CWSC prepareda Water Supply Assessment(WSA)according to the requirements of Senate Bill 610 (SB 610) in order to evaluate their potential to supply watertothe Project with the constraints placed on future supply from SFPUC. The WSA details CWSC’s approach to meeting future demands in the SSF District. CWSC has developed an Integrated Long Term Supply Plan (ILTSP) that calls for: x Projected groundwater production rates, x Enhanced conservation measured, x Development of water supply transfers, and x Investigation into desalinization. Based on the ILTSP as discussed in the WSA, CWSC has concluded that they will be able to supply the projected demands of the SSF District and subsequently the Project. The complete WSA is located in Appendix B. 6.3WastewaterCollection System 6.3.1 The development of Phase I will increase the average wastewater flow from 0.09 mgd to 0.14 mgd. Phase I will increase the peak flows from 0.25 mgd to 0.38 mgd Theconstruction of the totalProject will increase the average wastewater flow conveyed in the City’s collection system an additional 0.28 mgd and the peak flow by0.61.Table 6 summarizes the net change in wastewater flow resulting from the development of Phase I and the total Project. Sewer TrunkLines FINAL –January 201124 pw://Carollo/Documents/Client/CA/South SF/8543A00/Deliverables/OPSB_Study.doc (Draft) Evaluation criteria from the East of 101 Sewer Master Plan were used to determine the impacts from the increasedwastewaterflows.Thecriteria defines a sewer trunk as deficient if the depth of flow to pipeline diameter (d/D) for PDWF conditions is greater than 0.9. During PWWF, a sewer trunk is deficient if the hydraulic grade line rises to within one foot of the manhole rim elevation. Pump Stations are evaluated based on their firm capacity. The firm capacity is the pump stations capacity with its largest pump out of service. Pump stations need to have sufficient firm capacity to convey peak flows. According to modeling results the existing sewer trunk lines have enough capacity of convey the increase in flow resulting from the construction of Phase I. The projectedincrease in flowfrom the construction of the total Projectcreates capacity deficiencies in the existing Oyster Point Subtrunk from Pump Station No. 2 to the intersection of Oyster Point Boulevard and Gull Road. The deficient segments of sewer trunk are illustrated in Figure 12.

The existing firm capacity of Pump StationNo. 2 is 1.4 mgd. Existing peak flowsat Pump Station No.2 reach 1.1 mgd. With the development of Phase I, the peak flows to Pump Station No. 2 increase to 1.16 mgd. Development of the totalProject, increases the peak flows to1.6 mgd.Therefore, the development of Phase I will not trigger an upgrade of Pump Station No. 2., but once the total Projectis developed Pump Station No. 2 will need to be expanded to afirm capacity of 1.6 mgd. 6.3.3 Wastewater Collection System Improvements The improvements specified in the East of 101 Master Plan call for the Oyster Point Subtrunk to be increasedfrom Pump Station No. 2 to the intersection of Oyster Point Boulevard and Eccles Avenue. The improvement calls for a new 18-inch diameter pipe to replace the existing 12-inch sewer that continues northward on Gateway Boulevard from Pump Station No. 2. The portion that continues eastward along Oyster Point Boulevard from Gateway Boulevard consists of a new 15-inch diameter sewer to replace existing 10- inch and 12-inch diameter sewers. A new 12-inch diameter section is needed to replace approximately 800feet of existing 8-inch diameter sewer trunk to the intersection of Oyster Point Boulevard andEccles Avenue. An additional 700 feet of 8-inch diameter sewer trunk from Eccles Avenue to Gull Road need to be upsized to a 12-inch diameter trunk sewer. This segment of sewer trunk was not included in the recommendations in the East of 101 Master Plan. The East of 101 Master Planalsorecommends upgrading Pump Station No. 2 to a firm and total capacity of 3.5 mgd and 4.9 mgd respectively. The recommended capacities in the East of 101 Master Plan would allow Pump Station No. 2 to have capacity for growth to 2030. 6.4Wastewater Treatment As discussed earlier, the Project will increase the average dry weather flow by 0.28 mgd andthe peak flow by0.61mgd.The City is currently updating the WQCP facilities plan to evaluate the existing and futuretreatmentcapacity needs. Carollo Engineers issued a draft Facilities Plan report (Draft Facilities Plan) in April 2010. The Draft Facilities Plan estimates average flow projections through the year 2040 to reach 10.3 mgd, which is lower than the existing average dry weather plant capacity of 13 mgd. The increase of flow is within the project flows forthe East of 101 area. Based on the findings from the Draft Facilities Plan, the increased flows from the Project will not impact the WQCP. FINAL –January 201127 pw://Carollo/Documents/Client/CA/South SF/8543A00/Deliverables/OPSB_Study.doc (Draft) 6.5Storm Drainage System Impacts As described above, the existing Project site consists of approximately 57 percent impervious surfaces. Table 6summarizes the existing and proposed pervious surface areas for the existing Phase I project area and for the total Project site. 6.5.1 Phase I Storm Drainage Impacts ForPhase I,the Developer is proposing to construct the reconfigured intersection of Oyster Point and Marina Boulevards, along with the demolition of the Oyster Point Inn, the marina services building and other adjacent office buildings. Table 7summarizes the changes to the pervious and impervious areas as a result of Phase I and the initial infrastructure construction. The development of Phase I along with the +initial infrastructure construction, demolition,and site workwillincrease the pervious area by 2.9 acres. Figure 13 shows the area affected by the construction of Phase I and the supporting infrastructure. Based on these results the construction of Phase I will not have an impact on the storm drainage system. 6.5.2 Total Project Storm Drainage Impacts The construction of the totalProject will increasein the impervious areaby the modest amount oftwo acres,or 2.6 percent.Figure 14 shows the pervious and impervious areas for the total Project. 6.6Storm Drainage System Improvements The slight increasein stormwater flow with the construction of the total Projectwillbe mitigated by implementingthe requirements in Provisions C3 of the City’s NPDES permit. The complete text of Provision C3 is provided in Appendix A. Provision C3requires the permit holder to use itsplanning authority to impose best management practices on new developments or redevelopment projects. The practices include: x source controls, x stormwater treatment measures to address both soluble and insoluble pollution discharges, x limitrunoff flows from new developments and redevelopment projects, x site designmeasures, Site design measures include: x low impact development (LID) techniques, x post construction stormwater site design treatmentcontrols (for example; directing runoff to vegetative areas, vegetative swales, tree wells or bioretention gardens), FINAL –January 201128 pw://Carollo/Documents/Client/CA/South SF/8543A00/Deliverables/OPSB_Study.doc (Draft) Ta b l e 7 N e t C h a n g e t o I m p e r v i o u s S u r f a c e s Oy s t e r P o i n t R e d e v e l o p m e n t U t i l i t i e s S t u d y La m p h i e r - G r e g o r y Pr e - P r o j e c t (1 ) Po s t - P r o j e c t (2 ) ( 3 ) Net Change(4) La n d A r e a A r e a ( a c r e s ) % o f A r e a A r e a ( a c r e s ) % o f A r e a A r e a ( a c r e s ) % o f A r e a Ph a s e 1 Pe r v i o u s A r e a 1 7 . 9 5 4 2 0 . 8 6 3 + 2 . 9 + 9 Im p e r v i o u s A r e a 1 4 . 9 4 6 1 2 . 0 3 7 - 2 . 9 - 9 To t a l A r e a 3 2 . 8 1 0 0 3 2 . 8 1 0 0 - 0 . 0 - 0 To t a l P r o j e c t Pe r v i o u s A r e a 3 4 . 7 4 3 3 2 . 6 4 1 - 2 . 1 - 3 Im p e r v i o u s A r e a 4 5 . 3 5 7 4 7 . 4 5 9 + 2 . 1 + 3 To t a l A r e a 8 0 . 0 1 0 0 8 0 . 0 1 0 0 + 0 . 0 + 0 No t e s : 1.

The Project will not cause a significant impact to the existing 16-inch water main. 7.1.2 Water Supply System x According to the WSA, CWSC will have sufficient water supply to serve the SSF Distinct for the next 20-years. x Future water supply for the SSF District is to be met by implementation of CWSC’s Integrated Long Term Supply Plan. 7.2WastewaterSystem x The development of Phase I will increase the average wastewater flows from 0.09 mgd to 0.14 mgd. The peak wet weather flow after the development of Phase I will increase from 0.25 mgd to 0.38 mgd. x The total Project will increase the current average wastewater flows from 0.09 mgd to 0.37 mgd. The peak wet weather flows will increase from 0.25 mgd to 0.86 mgd. FINAL – January 201132 pw://Carollo/Documents/Client/CA/South SF/8543A00/Deliverables/OPSB_Study.doc (Draft) 7.2.1 x The development of Phase I will not have an impact on the existing wastewater collection systemdownstream of the Project site. Wastewater Collection System x The additional wastewater flows from the construction of the total Project willexceed the hydraulic capacities of theexisting Oyster Point Subtrunk, and Pump Station No. 2. x To provide the required sewer capacity, the Oyster Point Subtrunkwill need to be replaced with a larger sized trunk line, with sizes ranging from12, 15, and 18- inches. x Pump Station No. 2 currently has a firm capacity of 1.4 mgd. Wastewater flows from the project will increase peak flows to 1.6 mgd. Pump Station No. 2 will need to upsized to a firm capacity of 1.6 mgd to have capacity to serve the Project. 7.2.2 According to the South San Francisco/San Bruno Water Quality Control Plant Draft Facilities Plan Update (Carollo, April 2010), the WQCP has sufficient capacity through the year 2030, includinga reserve capacityfor flows fromthe East of 101 area. Accordingly, the Project willisnotexpected to appreciably impact thewastewater treatment plant. Wastewater Treatment System 7.3StormDrainage System The volume of stormwater is directly related to the amount of imperviousarea within a development. The percentage of impervious surfaces from developing Phase I will slightly decrease from 46 percent impervious to 37 percentimpervious. After the development of the totalProjectthe percent imperviouswill slightly increase.The existing developmentis 56.7 percent impervious, while thetotalProjectsite is estimated to be59.3 percentimpervious. This increase will cause a slight increase in stormwater flows. Stormwater runoff is regulated by the City’s National Pollution Discharge Elimination System (NPDES) permit. The City’s NPDES Permit specifies that redevelopment projects are subject to Provision C3. Provision C3will require the Project developers to implement BMPs and low impact development (LID) techniques employing landscape based treatment measures.
