This Initial Study iden environmental impacts associated with demolition, grading, construction and future occupancy of the Project which includes any reasonably foreseeable impacts associated with the Project in its entirety. CEQA (PRC Section 21065) defines a Project as: An activity which may cause either a direct physical change in t reasonably foreseeable indirect physical change in the environme the following: a)An activity directly undertaken by a public agency. b)An activity undertaken by a person which is supported, in whole through contracts, grants, subsidies, loans, or other forms of a or more public agencies. c)An activity that involves the issuance to a person of a lease, p certificate, or other entitlement for use by one or more agencie The Applicant is requesting entitlement approvals to expand an existing parking facility at 195 1 North Access Road, South San Francisco, CA. The existing Park SFO facility, constructed in 2001 and expanded in 2007, contains approximately1,306 parking spaces in a seven level 2 parking structure with approximately 629 additional spaces on an adjacent surface lot. The proposed project would expand Park SFO by removing the adjacent paved surface parking lot and constructing a seven level structure that would park an addi1,600 vehicles and connect to the existing seven-level parking structure.

The proposed project requires design review and modification to the existing conditional use permit to expand the parking structure. The project would also require an administrative waiver to the roof-top landscaping requirements contained in Section 20.330.010.L.8 of the Zoning Code. The proposed project (2013 Project) meets criteria b and c, identified above and therefore requires environmental review. Preparation of an environmental a environmental determination is required prior to or simultaneously with entitl Environmental review does not constitute Project approval, but is an independent analysis of potential Project impacts and mitigation measures. The Lead Agency may, after review of the entirety of the record, find that the environmental analysis is or conditionally approve the Project based upon environmental anmerits review. The Lead Agency for this document is the City of South San Francsco. The Planning Commission will deliberate and take action on the 2013 Project entitlements and environmental documentation. These actions will take place in legally-noticed public hearings. This Initial Study, City Project Number: P12-0048, ND12-0003, UPM12-0003 and DR-0022 is for the 2013 Project identified 195 North Access Road in South San Francisco, California (APNs: 015-180-020 and 015-173-160). Total site area is approximately seven acres (6.96). The site aincludes the 5.71 acre parcel supporting the existing parking garage (2001 Project)and the adjacent 1.25 acre parcel currently containing surface parking (2007 Project). The 2007 Project would be demolished, re-graded and reconstructed with a seven-level parking structure. Some demolition of the north wall of the 2001 Project would be necessary to connect the two structures. The existing vertical entrance and exit ramps would be expanded to provide access to the expanded facility (referred to as the 2013 Project). New stairs and a lobby with two elevators are proposed as part of the 2013 Project. Drive aisles would be constructed and connected to allow vehicles to flow between the new and existing facility. The 2013 Project architecture is proposed to be similar to and compliment the existing facility.The totality of these actions, as well as the daily operations of the expanded facility, constitutes the 2013 Project.

The 2007 parcel 1 is owned by the City of South San Francisco and leased to Mr. Roms, the Project sponsor. The 2013 Project would demolish the 2007 Project and construct a seven-level parking structure connecting to the existing 2001 Project. The site is located in the East of 101 Planning Area, in the sou North Access Road. North Access Road and San Bruno Canal are immediately south of the site. South of North Access Road is another parking structure. San Francisco International Airport is property is 200 feet south of the site with its main operations approximately 1,300 feet further south. San Francisco Bay is directly east, the City of South San Francisc the north and an aviation fuel tank farm is to the west.

SPH-EC ITE LANNING ISTORYXISTING ONDITIONS The City received a development application in 1997 that trigger entitlement review to construct the existing Park SFO facility. The 1997 review resulted in the City adopting a Mitigated Negative Declaration of Environmental Signi Monitoring and Reporting Program (MMRP) for site development and. Amendments to the 1999 General Plan, East of 101 Area Plan and Zoning Ordinance to designate and zone the site as Mixed Industrial (MI) to allow a parking facility that includes , and parking on the unused dry docks were also approved. Three of the dry docks are leased from the City and one is owned by the Project sponsor. Other actions included authorization and execution of a development agreement and land lease agreements; a lot line adjustment; and use permit and design review approvals, with conditions of approval. The project was approved in April, 1998 and The 2013 Project is the demolition of the 1.25-acre surface parking lot paved in 2007 and construction of a sev-level 1 parking structure connecting to the parking structure constructed in 1998.

Research on envirostor.dtsc.ca.gov does not indicate hazardous or toxic issues associated with the property although there may be monitoring wells on the property in connection with monitoring nearby properties (website accessed December 5, 2012). Chapter 3, Section 3.8 Hazards and Hazardous Materials describes site conditions in more detail. Luis DaSilva South San Francisco Fire Marshal did not identify hazardou with the property (memorandum June 25, 2012). The Chief Planner, Ms. Susy Kalkin, concurs with these findings.

BCDC(BCDC)BT AY ONSERVATION AND EVELOPMENT OMMISSION AY RAIL AND BA AY CCESS The City, in 1998 amended the East of 101 Area Plan in part to relocate a portion of the planned-for San Francisco Bay Trail (Bay Trail) along with the first entitlements for Park SFO. BCDC in 1996/97 approved a trail alignment for San Francisco International Airport (SFO) realigning the Bay Trail entirely west of the SFO terminating at the comer of South Airport Boulevard and North Access Road. The rerouting requested by Mr. Simms and approved by the City in 1, resulted in connecting the two trail segments and provided a direct route back to the shoreline north of the 2 SFO and the Project site (see Figure 2.4 Bay Trail). A regional view of the Bay Trail may be located on www.abag.ca.gov/bayaarea/baytrail/map.html. Mr. Simms constructed a 32,000 square foot public park on the southern-most dry dock as part of the 1998 Project. The Bay Trail is just south of the park. The realignment realized in the late 1990s provides a public park, Bay Trail links north of the Project are experience by avoiding the odoriferous activities of the Water Q as noted in the City 1997 staff reports. 2 Prior to the Citys amendment the Bay Trail was planned to leave northerly parallel to the dry docks (through the Project site) adge the canal and connect further to northern portions of the City.

A possible exception to this would be to accommodate concrete pours which requires a consistent and const pour is completed. Typically, concrete pours would occur on Thursdays or Fridays to take advantage of weekend downtime allowing the concrete to adequately cure before construction resumes on the following Monday. Should Saturday pours be necessary, the activity would occur between the hours of 8:30 AM and 5:00 PM. These proposed hours of construction are in conformance with the Citys noise ordinance outlined in Chapter 1, Introduction, Section 1.5.5 3 which limits weekday construction from 8 AM to 8 PM. 3 Construction noise is regulated through the Municipal Code (8.32 to 8 P.M.

The construction would occur over a 16 month period. Chapter 2 Project Description provides further information on Project phasing and constructio Project construction would generate short-term emissions of criteria pollutants, including fugitive dust and equipment exhaust emissions. The BAAQMD CEQA Air Quality Guidelines recommend quantification of construction-related exhaust emissions and comparison of those emissions to significance thresholds. Therefore, thisanalysis includes quantification of construction emissions and comparison of the emissions to the BA significance thresholds. The CalEEMod (California Emissions Est quantify project construction emissions of criteria pollutants (see Appendix A for emissions estimate assumptions). Air Quality Table 2 provides the estimated short-term construction emissions that would be associated with the Project and compares those emissions to the construction exhaust emissions.

The methodology includes the following: 7 Based upon trip generation rates found at commercial airports in Manual (9th Edition - 2012), pm peak hour trip generation is about 5.6 to 6 percent of daily generation. PARKSFO–ISP3-15 NITIAL TUDYAGE C3:EC HAPTER NVIRONMENTAL HECKLIST Project is consistent with an applicable congestion management p by the county congestion management agency for designated roads regional transportation plan, and local congestion management agency plans. The project traffic would increase traffic volumes at affected i than 44,000 vehicles per hour. The project traffic would increase traffic volumes at affected i than 24,000 vehicles per hour where vertical and/or horizontal mixing is substantially limited (e.g., tunnel, parking garage, bridge unde street canyon, below-grade roadway). The two signalized intersections at the South Airport Boulevard/I-380 interchange as well as the North Access Road/I-380 end of freeway intersection just south of the site are curre operating at Levels of Service (LOS) A and B during AM and PM co conditions. All three analysis intersections would have LOS A or B during the AM and PM peak 8 hour operation in the year 2015 with the addition of Project tra. Two of the three analysis intersections would have LOS A or B during the AM and PM peak hour operation in the year 2035 with the addition of Project traffic. In addition, the South Airport Boulevard/North Access Road/I-380 westbound on-ramp intersection would maintain LOS B during the AM peak hour and LOS D during the PM peak hour operation with the addition of Project t The additional traffic would not exceed the screening criteria based on the size of the facility, the anticipated resultant traffic volumes, and the anticipated LOS a . CI UMULATIVE MPACTS The BAAQMD CEQA Air Quality Guidelines recommend that cumulative air quality effects from criteria air pollutants also be addressed by comparison to the B significance thresholds. Project-related emissions would be below the thresholds with implementation of the measures the City requires by law (see Introduction, Chapter 1, Section 1.2.2) as shown in Air Quality Tables 2 through 4. d) Impacts to Sensitive Receptors Significance Criteria: The significance of impact to sensitive receptors is dependent of contracting cancer from exposure to carcinogenic toxic air contaminants (TACs) such as DPM, or of having adverse health effects from exposure to non-carcinogenic TACs. A project is considered to be significant if the incremental cancer risk a For cumulative analysis of cancer risk, BAAQMD recommends that the risks from a within a 1,000 foot radius of the source or receptor be assessed 8 The trip generation and intersection levels of service are from -specific traffic analysis conducted by Crane Transportation Group and discussed in Section 3.16 Transportatio P3-16 PARKSFO–IS AGE NITIAL TUDY C3:EC HAPTER NVIRONMENTAL HECKLIST increased risk threshold of 100 in one million. The non-cancer hazard index significance threshold of 1.0 is defined in the BAAQMD CEQA Air Quality Guidelines. For cumulative analysis of non-cancer hazard index, BAAQMD requires that the hazards from all s a 1,000 foot radius of the source or receptor be assessed and coto a cumulative hazard index threshold of 10. The BAAQMD has established a separate significance threshold for health as emissions of PM2.5 are associated with health risks. 3 BAAQMD significant threshold for PM2.5 impacts is an average annual increase of 0.3 µg/m. For cumulative analysis, BAAQMD recommends that the PM2.5 concen sources within a 1,000 foot radius of the receptor be assessed a 3 threshold of an average annual increase of 0.8 µg/m. CR ANCER ISK Cancer risk is defined as the lifetime probability of developing carcinogenic substances. Cancer risks are expressed as the chan cancer, for example, ten cancer cases among one million people e Following HRA guidelines established by California Office of Env Assessment (OEHHA) and BAAQMDs Health Risk Screening Analysis Guidelines, incremental cancer risks were calculated by applying toxicity factors to modeled TAC concentrations i to determine the inhalation dose (milligrams per kilogram of bod-day]). See Appendix A for details. Construction Related Impacts As a result of construction activities (with implementation of the measures the City requires by law), the unmitigated maximum cancer risk for a residential-adult receptor would be 0.18 per million and for a residential-child would be 2.0 per million. Operational Related Impacts The maximum cancer risks from the Project operations for a resid-adult receptor would be 0.30 per million and for a residential-child would be 0.15 per million with implementation of the measures the City requires by law. Total Project Impacts The maximum cancer risks from the Project construction and opera(with implementation of the measures the City requires by law), the unmitigated maximum cancer risk a residential- adult receptor would be 0.30 per million and for a residential-child would be 2.0 per million with implementation of the measures the City requires by law. PARKSFO–ISP3-17 NITIAL TUDYAGE C3:EC HAPTER NVIRONMENTAL HECKLIST N-CHI ONANCER EALTH MPACTS Both acute (short-term) and chronic (long-term) adverse health impacts unrelated to cancer are measured against a hazard index (HI), which is defined as the ra exposure concentration from the Project to a published reference exposure level (REL) that could cause adverse health effects. The RELs are published by OEHHA based on epidemiological research. The ratio (referred to as the Hazard - carcinogenic substance that affects a certain organ system is added to produce an overall HI for that organ system. The overall HI is calculated for each organ highest-impacted organ system is greater than 1.0, then the impact is co significant. The chronic reference exposure level for DPM was established by 3 5 g/m. There is no acute REL for DPM. However, diesel exhaust does other compounds, which do have an acute REL. Based on BAAQMDs acrolein emissions are approximately 1.3percent of the total DPM emissions. The acute REL 93 for acrolein was established by the California OEHHA as 2.5 g/m. The chronic HI would be 0.01. The acute HI would be 0.01. PM2.5 Concentration Dispersion modeling was also used to estimate exposure of sensit-related concentrations of PM2.5. Because emissions of PM2.5 are associa BAAQMD has established a separate significance threshold to protublic health. The BAAQMD guidance requires inclusion of PM2.5 exhaust emissions on fugitive dust emissions are addressed under BAAQMD dust control by law to be implemented into Project construction, see Introduction, Chapter 1, Section 1.5.2). The unmitigated maximum annual PM2.5 concentration as a result 3 construction would be 0.02 µg/m. Cumulative Impacts The BAAQMDs CEQA Air Quality Guidelines include standards and methods for determining the significance of cumulative health risk impacts. The method e health risk requires the addition of the health risks from permi in the vicinity of a project (i.e., within a 1,000-foot radius of the source, also considered the zone P3-18 PARKSFO–IS AGE NITIAL TUDY C3:EC HAPTER NVIRONMENTAL HECKLIST of influence for a health risk analysis), then adding the health risks of the Project impacts to determine whether the cumulative health risk thresholds are exce The BAAQMDs CEQA Air Quality Guidelines include standards and methods for determining the significance of cumulative health risk impacts. The method for determining cumulative health risk requires the tallying of health risk from permitted vicinity of a project (i.e., within a 1,000-foot radius of the source or new receptor), then adding the Project impacts to determine whether the cumulative health risk thresholds are excee BAAQMD has developed a geo-referenced database of permitted emissions sources throughout the San Francisco Bay Area, and has developed the Stationary Source Risk & Hazard Analysis Tool (dated May, 2011) for estimating cumulative health risks from per sources are located within 1,000 feet of the Project.

Since the June 2007 CARB hearing, CARB staff has evaluated all 48 recommendations submitted by stakeholders and several internally- generated staff ideas and published the Expanded List of Early Action Measures To Reduce Greenhouse 17 Gas Emissions In California Recommended For Board Consideration. Pursuant to AB 32, CARB adopted a Scoping Plan in December 2008, outlining measures to meet the 2020 GHG reduction limits. In order to meet these goals, California must reduce its GHG emissions by 30 percent below projected 2020 business as usual emission levels o 18 15 percent from todays levels.The Scoping Plan estimates a reduction of174 MMTCOe 2 (about 191 million U.S. tons) from the transportation, energy, agriculture, global warming potential sectors (see GHG Emissions Table 1). CARB has identified an 19 implementation timeline for the GHG reduction strategies include Some measures may require new legislation to implement, some will req already been developed, and some will require additional effort Additionally, some emissions reductions strategies may require t under CEQA.

CSSF ITY OF OUTH AN RANCISCO The City of South San Francisco does not have an adopted plan or GHG emissions, although many of the Citys policies and ordinanc-such as one of the regions most aggressive TDM programs-achieve the same objective. Currently, the City is preparing a community-wide comprehensive Climate Action Plan (CAP). The CAP will prov policies, and programs to reduce GHG emissions, climate change a goals of AB 32 and SB 375. In preparation of the CAP, the City Operations Emissions Inventory, a community-wide Greenhouse Gas Emissions Inventory, and has recently adopted a Bicycle Master Plan. Although the general plan did not specify policies and programs designed to reduce GHG emissions, many of the Plan this objective by promoting development that is less reliant on City of South San Francisco Zoning Ordinance Update (December 17, 2009), South San Francisco emitted approximately 527,000 tons of CO2e in 2005 fro half of which were from transportation. I MPACTS a) Generation of Greenhouse Gas Emissions Significance Criteria: The BAAQMD CEQA Air Quality Guidelines identify a project specific threshold of either a bright-line threshold of 1,100 metric tons of COe per year or an efficiency 2 threshold of 4.6 metric tons of COe per year per service population (i.e., the number of 2 P3-26 PARKSFO–IS AGE NITIAL TUDY C3:EC HAPTER NVIRONMENTAL HECKLIST residents plus the number of employees associated with a new development) as resulting in a cumulatively considerable contribution of GHG emissions and a cu Alternatively, a project that is found to be consistent with a Q than significant impact to global climate change.

Both pampas grass and highly invasive French broom (Genista monspessulana) occur along the north bank of San Bruno Creek, just south of the exist and the landscape plantings along the canal-side of the paved Bay Trail (see Figure 2.4 in Chapter 2) segment adjacent to the site. These planting areas are in poor cond exposed concrete rubble, and very little visible soil necessary establishment. The site boundaries extend down the slope of each of the finger -marsh zone of the tidelands of San Bruno Canal. The mid-marsh zone along the shoreline of the fingers, between the unvegetated mudflats and open water of San Bruno Canal and the uplands that are not under tidal influence, supports native pickleweed (Salicornia virginica), with gum plant (Grindelia stricta) and salt grass (Distichlis spicata) at higher elevations. Most of the former drydocks are now exposed mudflats during low tides. The upland areas of the site provide only marginal habitat for s suburban areas. However, the adjacent tidelands support scattere saltmarsh and mudflats, which are highly sensitive habitat. The species of invertebrates which provide foraging opportunities fo willets, godwits, dowitchers, sandpipers, snipes, turnstones, an of the adjacent turning basin provides foraging opportunities for grebes, corm coots, gulls, kingfishers, terns, and pelicans. The Project site is paved for surface parking with approximately ornamental landscaping. Given the absence of essential habitat features, it appears unlikely t 22 the site supports any special-status plant or animal species. No occurrences of species with special-status have been mapped in the Project vicinity by the California Natural Diversity Base. A small population of the state and federally-endangered California clapper rail (Rallus longirostris obsoletus) was reported in the salt marsh habitat of San Bruno Point in 1975. Suitable foraging habitat for this species is absent in the scattered clumps of pickleweed along the lower elevations of the fingers on the site. There remains a possibility that special-status bird and fish species 22 As defined further below under Regulatory Framework,special-status species are plants and animals that are legally protected under the state and/or federal Endangered Species Acts considered rare enough by the scientific community and trustee aegard to protection of isolated populations, nesting or denning locati habitat.

The Regulatory Framework below provides a detailed discussion of the regulatory structure related to wetlands and jurisdictional waters. The open waters of the former drydocks and San Bruno Canal are j by the U.S. Army Corp of Engineers (Corps), Regional Water Quality Control Board (RWQCB), and California Department of Fish and Wildlife (CDFW). All modifications associated with the Project would be located in upland areas at the existing paved parking lot, and would not affect any jurisdictional wetlands or waters. RF EGULATORY RAMEWORK Local, State, and federal regulations have been enacted to provide for the protection management of sensitive biological and wetland resources. The following section outlines the key local, State, and federal regulations that apply to these re F EDERAL The U.S. Fish and Wildlife Service (USFWS) is responsible for protection freshwater organisms through implementation of the federal Endan the Migratory Bird Treaty Act (MBTA).

WOWUS ETLANDS AND THER ATERS OF THE NITED TATES Although definitions vary to some degree, wetlands are generallyare periodically or permanently inundated by surface or ground water adapted to life in saturated soil. Wetlands are recognized as i national level due to their high inherent value to fish and wild and flood waters, and water recharge, filtration and purificatiounctions. The CDFW, Corps, and RWQCB have jurisdiction over modifications to river banks, lakes, stre other wetland features. Technical standards for delineating wetlands have been developed the Corps and the United States Fish and Wildlife Service (USFWS), which generally define wetlands through consideration of three criteria: hydrology, so The CWA was enacted to address water pollution, establishing regulations requirements regarding construction activities that affect storm water, dredge and fill material operations, and water quality standards. The regulatory program requires that discharges to surface waters be controlled under the National Pollutant Discha (NPDES) permit program which applies to sources of water runoff, private developments, public facilities. Under Section 404 of the CWA, the Corps is responsible for regul material into waters of the United States. The term waters inands and non-wetland bodies of water that meet specific criteria as defined in the Co three of the identified technical criteria must be met for an ar under Corps jurisdiction, unless the area has been modified by human activity.

City of South San Francisco General Plan The Open Space and Conservation Element of the City of South San Francisco General Plan contains a number of policies related to protection of sensitive biological and wetland resources that are applicable to the site. The policies are: 7.1-G-1: Protect special status species and supporting habitats within So Francisco, including species that are State or federally listed reatened, or Rare. 7.1-G-2: Protect and, where reasonable and feasible, restore saltmarshes 7.1-I-2: As part of the Park, Recreation and Open Space (PROS) Master Pla institute an ongoing program to remove invasive plant species frecologically sensitive areas, including Sign Hill Park, Colma Creek Linear Park, Bayfro other City-owned open space, as depicted in Figure 7-1. 7.1-I-3: As part of development approvals on sites that include ecologica habitat designated in Figure 7-2, require institution of an on-going program to remove and prevent the re-establishment of the invasive species and restore the native spe P3-34 PARKSFO–IS AGE NITIAL TUDY C3:EC HAPTER NVIRONMENTAL HECKLIST 7.1-I-4: Require development on the wetlands delineated in figure 7-1 to complete assessments of biological resources. 7.1-I-5: Work with private, non-profit conservation, and public groups to secure funding for wetland and marsh protection and restoration projects. East of 101 Area Plan The East of 101 Area Plan was adopted by the City of South San Francisco in July 1994. The Area Plan includes a Conservation Element that contains policies intended enhance natural resources in the East of 101 Area. Policies rel: Policy CON-1: Prior to construction of development projects on sensitive res lands the City shall require an applicant to conduct a formal we project site The results of the wetlands delineation shall be ma project specific impacts associated with sensitive habitats Policy CON-2: The City shall require that developments comply with all appli and federal laws and regulations regarding protection and replac Policy CON-4: The City shall take all feasible measures to preserve any sensitive plant and animal species that occur in the East of 101 Area.

I MPACTS a) Special-Status Species and Nesting Habitat Significance Criteria: The Project would have a significant impact if were to result in a substantial adverse effect on special-status species, as identified in 3.5 Biological Resources a, above. Essential habitat for special-status species would not be affected by the Project. The addition to the parking structure would be located adjacent to the open wate San Bruno Canal, where special-status birds and fish may occasionally forage and disperse. The Project would have no direct affect on this area and is not likely to di and dispersal activity for these species. Suitable nesting habitat for State and federally-listed bird species is absent on the site. However, the few native shrubs along the perimeter of the fingers could be used for nesting common bird species. These nests would be protected under the f in active use.

Construction activities during the bre incidental loss of fertile eggs or nestlings or nest abandonment A standard requirement is to either initiate construction during t-nesting season, which in San Mateo County is September 1- January 31, or to conduct a nesting survey within seven days prior to initial grubbing and construction to determine whether any active nests are present that must be protected until any young have fledged and are no longer. Protection of the nests, if present, would require that construction setbacks be provided during the nesting and fledging period, with the setback depending on t, degree to which the individuals have already acclimated to other on-going disturbance, and other factors.

South San Francisco Municipal Code Section 13.30.020 defines a Protected Tree as o 48 or more when measured 54 above natural grade; a tree or stand of trees designated by the P3-38 PARKSFO–IS AGE NITIAL TUDY C3:EC HAPTER NVIRONMENTAL HECKLIST Director of Parks and Recreation as one of uniqueness, importanc location or unusual appearance, historical significance or other Director of Parks and Recreation has determined each tree is dependent on survival. There are no trees on the site which meet the Citys definition no adverse impacts are anticipated. Biological Study and Protection of Resources As indicated in the Regulatory Framework discussion, the City of South San Francisco General Plan and the East of 101 Area Plan contain policies relevant to the site and Project. Policies 7.1-G-1 and 7.1-G-2 of the general plan pertain to protection of special-status species and wetland habitat. As discussed under criterion a and c, the Project woul for special-status species or nearby wetland habitat associated with the San Biology Mitigation 1 is identified to ensure Project construction does not disrupt and bird nesting activity, in the remote instance new nests were establis consistent with the intent of these goals. The biological asseshis Initial Study preparation provides the review called for in Policy 7.1-I-4. The Project site is located adjacent to wetlands but does not contain wetlands.

The bi assessment conducted as part of this Initial Study preparation pes for the review called for in East of 101 Area Plan Policies CON-1 and CON-5 and implements the biological review required by Figure 7-2 of the General Plan. No wetlands would be affected by the Project, as discussed above under criterion c, above. Therefore the ProjectPolicy CON-2. No significant adverse impacts on special-status species are anticipated (as discussed above under criterion a). The Project would not conflict with Policies CON-4 and CON-6. Policy CON-7 includes standards for new development adjacent to sensitive habitat, including the wetlands adjacent to the site, addressing requirements for n PARKSFO–ISP3-39 NITIAL TUDYAGE C3:EC HAPTER NVIRONMENTAL HECKLIST new lighting, restrictions on entry, and controls on run-off. The policy states that the City will review developments proposed within the 100-foot buffer area on a case-by-case basis. The policy requires a biological assessment which is conducted throuinitial study and implementation of identified mitigation measures, if warranted.Mitigation measures are identified in this Initial Study to reduce biological impacts to a less-than-significant level. Left unmitigated the spread of invasive exotic plant materials w Implementation of Biology Mitigation 2 would reduce the spread of invasive species on the site, provide for habitat enhancement through establishment of n compliance with General Plan Policies 7.1-I-2 and 7.1-I-3. Implementation of Biology Mitigation 2 would reduce Project impacts to less-than-significant with respect to habitat quality and policy compliance.

Lighting The application materials note that lighting would be designed to mi skyward and are silent on light seepage towards the Bay. Chapter 1, Legislative Framework, Section 1.5.1 Aesthetics stipulate the Citys requirement to control off-site glare and light. Municipal Code Section (Zoning) 20.300.008.4 also requires light to be shielded so as not to produce obtrusive glare onto the public right-of-way or adjoining properties. Protection of the Bay lands from an additional substantial light source, such as n-directed or unshielded light associated with doubling the size of the existing parking struct noted in the East of 101 Area Plan Policy CON-7 and left unmitigated could result in a significant impact. Implementation of Biology Mitigation 3 would reduce the lighting impact to less- than-significant. BIOLOGY IMPACT 3: SUBSTANTIAL INCREASE IN LIGHT ONTO BAY LANDS MAY REDUCE THE HABITAT VALUE OF THE TIDAL AREA (WETLAND HABITAT) AND WOULD CONFLICT WITH POLICY CON-7.

S ETTING PS ROJECT ITE The Project site is approximately seven acres in area (6.96). The existing Park SFO (2001 Project) parking garage sits on 5.71 acres adjacent to and south of the 1-acre site that would support the parking garage expansion. The 1.25-acre site (2007 Project) is paved and used as surface parking associated with the existing Park SFO parking ga As noted throughout this document, prior to 2001, the 1.25 acre 2007 Project site supported industrial land uses, ship repair, warehouse and freight forwarding, and from 2001-2003 was used as a composting area for the Citys Water Quality Control Plant. In 2007, the property owner received approvals from the City to pave the Project site and provide surface parking that is part and parcel to the existing Park SFO facility that was constructed in 1998. Therefore, the Project site has been paved and used for a surface parking lot as part of the Park SFO The site is relatively level and surface the elevation is approximately 11 feet above mean sea level (MSL) (Furgo West, Inc., March 2003, see below) San Francisco Bay is immediately east of the Project. Although the 2013 Geotechnical Report prepared by Furgo West makes note of a potential basement level parking area, this initial study analyzes an above grade parking structure only consistent with the plans submitted to the Planning Divisio RF EGULATORY RAMEWORK The City Engineering Division requires geotechnical reports as a projects to be constructed on vacant land, demolition and rebuil that require grading and additional loading (see Chapter 1, Section 5).

The dominant fault in this located about 3.4 miles southwest of the site. Other active faults in the area include t Gregorio fault located roughly 8.8 miles west-southwest, Monte Vista-Shannon is located 17.2 miles southeast, and the Hayward fault located on the order of 14.7 miles northeast. Additional faults in the area that are not considered active include the Sa roughly 2.2 and 3.3 miles southwest of the site, respectively. The Hillside fault, a northwesterly-trending escarpment aligned with a zone of sheared rocks on the knoll of Point San Bruno just south of Oyster Point, has also been mapped a short distance from the Project site. Until the late 1990s this fault was cons purposes. Subsequent geophysical studies conducted in the late 1990s usin-powered deep-penetrating sonar system found no evidence suggesting that the H active. Moreover, geologic observations of the Hillside fault e on San Bruno Mountain did not detect any recognizable offsets of current fault rupture hazard. Therefore, there is no evidence t within geologically recent time; however, it may be possible for sympathetic movemen imposed on this fault as a result of stress from major earthquak San Andreas and Hayward faults.

Liquefaction is a secondary seismic hazard involving saturated c sediments located close to the ground surface. Liquefaction occ decreases and pore pressure increases as a response to strong se During the loss of strength, the soil becomes mobile, and can mo vertically, if not confined. Soils most susceptible to liquefac uniformly-graded, fine-grained sands. The Project site is underlain by a non-saturated layer of medium dense to dense sand and gravel encountered within the upper five feet of undocumented fills and will likely induce a minor seismic settlement due to dynamic densification on the order of less than a quarter (1/4) inch during a design seismic event. The non-saturated medium dense to dense sand and silty gravel, along with the stiff clay and weathered rocks are not susceptiblThe Geotechnical Report (Furgo West, March 2003) concludes that the liquefaction potential necessary for liquefaction of materials under the Project site i low. Therefore, iv) Landslides Significance Criteria: The Project would have a significant environmental impact if i expose people or structures to substantial hazards from landslid A landslide is a mass of rock, soil and debris displaced down slope by sliding, flowing or falling. The Project site is flat. b) Erosion or Loss of Topsoil Significance Criteria:The Project would result in a significant environmental impact if it were result in substantial soil erosion or in the loss of topsoil. In absence of the NPDES C-3 requirements implemented by the City as a condition of buildin and grading permit issuance the Project would have a potential t construction. These requirements are described in detail in Section 3.8: Hydrology and Water PARKSFO–ISP3-51 NITIAL TUDYAGE C3:EC HAPTER NVIRONMENTAL HECKLIST Quality and in Chapter 1, Section 5. c) Geologic Instability Significance Criteria: The Project would have a significant environmental impact if l geologic unit or soil that is unstable, or that would become uns and potentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction or collapse. The Geotechnical Report, based upon subsurface testing (maximum depth of 35 feet) found that the site is located on Franciscan bedrock at a depth of 13 feet, a stable geologic unit. The site does contain undocumented fill consisting of dense silty gravel eight feet below existing grade, followed by five feet of very sl deposits. The Applicant indicates that an intention to export approximatel6,118 cubic yards of material and re-compact approximately 6,694 cubic yards of material from the site. The City Engineer (Mr. Sam Bautista, May 7, 2013) and Cotton Shires Associates (March 22, 2013) have indicated a concern with respect to site stability in absence of details reg-compacting of the soil. Specifically Cotton Shires notes: &concerns about the proposed use of undocumented fill materials resistance or support of slabs-on-grade (even with the propped 12 inches of over excavation). The Standard of Practice in the City is to remove undocumented fill or to obtain support for new structures (inclu-on-grade floors) with foundations that exceed through undocumented fill a competent native materials. The Standard of Practice in the [c]ity also does not include reliance on undocumented fill for passive resistance.

P3-52 PARKSFO–IS AGE NITIAL TUDY C3:EC HAPTER NVIRONMENTAL HECKLIST Project soils were identified as having a PI of 16 in the 2003 g According to Cotton ShiresAssociates, the Citys geotechnical consulting firm, a PI of 16 is a low plasticity level and suitable for the proposed development (Principal Engineering Geologist, May 1, 2013). Issues related toexpansive soils typically occur when the PI exceeds 25 (op., cit). e) Capability of Soils to Support Septic Tanks Significance Criteria: The Project would have a significant environmental impact if involved construction of septic systems in soils incapable of adequately or alternative wastewater disposal systems. The Project does not propose to build any new septic tank or alt The Project site is connected to the citys sanitary sewer system. Finding: There are no active faults underlying the site and the nearest one is the San Andreas Fault, located about three miles northeast. The hazard from fau considered to be low (Furgo West, 2003). Therefore, the Project significant impact on exposing people or structures to danger from surface rupture of a known earthquake fault.

Shell Oilowns and operates a fuel tank farm adjacent to and northwest of Project. Review on the National Pipeline Mapping System (www.npms.phmsa.dot.gov) indicates 25 that Shell Oil and Santa Fe pipelines may cross the 2013 Project site (viewed on January 29, 2013). The mapping system is a macro-based service and as such shall not be deemed completely reliable for the location of pipelines and other underground utilities; civil drawings or a Phase I ESA would provide this information. Review of Geotracker (https://geotracker.waterboards.ca.gov/) accessed on January 29, 2013 indicates that there are two closed hazardous spill sites on the2001 Project site, but none on the 2013 portion of the Project. One was an underground storage tank which leaked gasoline and was closed in 1992. The other was a sump that contained volatile organic compounds (VOCs). The site was closed and the monitoring wells destroyed in 2011. SMCDEH Director Dean Peterson issued a notice of case closure on August 8, 2011. Geotracker also indicates that some off-site monitoring wells from the Shell Oil Tank Farm may be located on the 2013 Project site. The wells appear to be northw2001 Project parking structure, on the 2013 Project portion of the site along. The architectural drawings do not show the location of the wells and civil drawings were not provided. The location of the monitoring wells and access thereto, must be shown on civil drawings to assure as-built conditions allow access to the wells. Absence of access t monitoring wells would be a significant impact. 24 Map Viewer identifies Deborah Price at (713) 241-2035 as the contact person for Shell Oil.

I MPACTS a) and b) Recreation Significance Criteria: The Project would have a significant environmental impact if it were to resu in an increase in the use of existing parks or recreational faci deterioration of these facilities could be anticipated, or if ittional facilities, the construction of which might have adverse physical effects on The 2001 Project created a public park on the southern-most dry dock, and relocated and improved the Bay Trail. The 2013 Project would not result in a significant increase in the use of existing parks or recreational facilities as the site would not , office or industrial purposes. Parks and recreational needs within the City are derived from th population and development projections contained in the South San Francisco General Plan. The 2013 Project is consistent with these development assumptions and wou population of the City, as noted in Sections 3.10 Land Use and Planning and 3.13 Population and Housing. Finding: Parks and recreational needs within the City are derived from th assumptions contained in the South San Francisco General Plan. The Project is consistent with planning projections and needs assessments based upon the projecgeneral plan and is not a population or employment generator. The Project would not result in an individual or cumulatively considerable impact on parks and recreation.

The existing surface parking constructed in 2007, would be demolished and a seven-level parking structure constructed in its place, connecting to the existing Park SFO facility constructed in 2001. Total on-site parking 28 would increase from 1,901 to 3,194 spaces. Access to all parking would remain in its existing location alonA circulation impact evaluation has been conducted for existing, year 2015 and year 2035 conditions, both with and without the 2013 Project. Locations evaluated are the two South Airport Boulevard intersections with I-380 ramps, the North Access Road intersection with the eastbound end of the I-380 freeway just south of the Park SFO site and the North Access Road/parking facility access driveway intersections. S ETTING The existing Park SFO(2001 and 2007 Projects) long term parking operation (serving the San Francisco International Airport-SFO) is located in the southern section of the City of South San Francisco adjacent to and north of North Access Road. The eastb-380 freeway terminates at a signalized intersection with North Acces site. Access between the site and the I-380 freeway is provided at two locations: via North Access Road just south of the site and via South Airport Boulevard to the west of the site. The I-380 ramps connecting to South Airport Boulevard also provide access to a northbound on- ramp to the U.S.101 freeway. The I-380 freeway connecting to North Access Road just south of the Project site also provides full access to the U.S.101 freeway via a series of north and southbound on- and off-ramps (see Traffic Figure 1 Area Map and Traffic Figure 2 Project Vicinity Roadways. Note: All figures are located at the end of the Traffic Sect tables are provided throughout the text). The existing Park SFO facility has a total of 1,901 long term pathe garage and 625 in surface parking lots to the north and east of the garage. Acces surface parking is provided via two side-by-side driveways on the outside of a 90-degree curve along North Access Road, about 180 and 270 feet north of the sig- 380 end of freeway intersection. The southerly driveway connect outbound traffic, while the northerly driveway is used primarily Appendix Traffic Figure 1  Existing Site Plan).

Each roadway is briefly described below (see Traffic Figure 2). North Access Road extends easterly from a signalized intersection with South Airport Boulevard and an I-380 westbound on-ramp. Approximately 900 feet to the east it curves 90 degrees to the south and Tees into a signalized intersection wit leg of the intersection). North Access Road then continues around the north and east edges of San Francisco International Airport (as the east leg of the intersection). North Access Road adjacent to the Project site has two north (west) bound through bound through travel lane, and a single east (south) bound left into the existing Park SFO facility as well as continuing to the-380 signalized intersection south of the site. Class II striped bike lanes are along the segment of North Access Road South Airport Boulevard and the I-380 ramp intersections. These lanes are part of the Bay Trail. South Airport Boulevard is primarily a four-lane arterial roadway in South San Francisco running parallel to and just east of the U.S.101 freeway. Addites are provided on the approaches to its signalized intersections with -380 eastbound off-ramp and an I-380 westbound on-ramp & North Access Road. Traffic Figure 3 Lane Geometrics and Intersection Control provides a schematic presentation of approach lanes and control intersections near the Project site. U.S. 101 is an eight-lane north-south freeway that provides access to the Project area extending from downtown San Francisco and Northern California to Los Angel U.S.101 is approximately 0.38 miles west of the Project site. U.S. 101 is a major regional freeway on the peninsula. The freeway has an Average Annual Daily Traff 229,000 vehicles south of I-380 including 15,900 vehicles during the peak hour.

Signalized Intersections. The 2000 Highway Capacity Manual (Transportation Research Board, National Research Council) methodology was utilized for signalized intersections. Operations are defined by the level of service and average control delay pe for the entire intersection with this methodology. Control delay is the portion of the total delay attributed to traffic signal operation for a signalized intersection. This includes delay associated with deceleration, acceleration, stopping, and moving up in the Traffic Table 1 summarizes the relationship between delay and LOS for signalizedrsections. 2.

Box 2505 South San Francisco, California 940831 Attention: Mr. Robert Simms Subject: Plan Review, REST Parking Facilities, South San Francisco, California Dear Mr. Simms: In accordance with your request, Fugro Consultants, Inc., (Fugro) has reviewed the geotechnical aspects of the Luk and Associates E-1 document dated July 9, 2013. This plan/grading plans should achieve the removal of the existing undocumented fill below the foot print of the proposed REST Parking Facilities, to be located at the northeast corner of North Access Road and south of the South San Francisco Water Pollution Control Plant (WPCP) in South San Francisco, California. Fugro previously performed a geotechnical investigation for the parking structure project, the results of which were presented in the report titled, “Geotechnical Investigation Report, REST Parking Facilities, South San Francisco, California”, dated March 12, 2003, and an updated Geotechnical Letter study dated February 12, 2013. It should be noted that in the February 12 update letter, Fugro recommended a partial reworking of the undocumented fills. As requested by the 3rd party reviewer for South San Francisco, Fugro is now recommending the entire undocumented fill below the foot print of the proposed parking structure be removed and reworked. During the actual grading, Fugro should be on site to verify that the fill has been completely removed. The undocumented fill that meets the requirements for fills in Section 4.1.4 of our March 2003 geotechnical report can be used to backfill the excavation resulting from the removal of the undocumented fill. The fill should be placed and compacted as required in Section 4.1.5 of our March 2003 report. A member of the Fugro group of companies with offices throughout the world. Rest Parking Facilities July 15, 2013 (Project No. 04.72130009) Our services have been limited to the review of the geotechnical aspects of the Luk and Associates E-1 document dated July 9, 2013, and have been provided in accordance with generally accepted geotechnical engineering principles and practices.

Intersection delay would be increased by no more than three locations. 6. Both project driveway access intersections along North Access Road should continue to function acceptably with increased traffic from Project expansio local area growth. The 25 to 30 percent growth in non-Project related traffic expected on North Access Road by 2035 at the Project site should not produce operational impacts at either Project driveway intersection, alt increased frequency of northbound traffic on the approach to the380 end of freeway intersection backing up in front of the garage during the PM peak traffic hour. However, these queues should clear quickly with a green light for northbo will be operating at good levels of service during both AM and P and signal timing adjustments can be made to more rapidly clear traffic backups from in front of the garage, if ever required. 7. Recommendations: No specific off-site circulation improvements are required. However, the Project should pay its required East of 101 Capital Improvements Program area traffic impact fee. III. PROJECT LOCATION AND DESCRIPTION The existing Park SFO long term parking operation (serving the S Airport) is located in the southern section of the City of South of North Access Road. The eastbound end of the I-380 freeway terminates at a signalized intersection with North Access Road just south of the Project si I-380 freeway is provided at two locations: via North Access Road just south of the site and via S. Airport Boulevard to the west of the site. The I-380 ramps con also provide access to a northbound on-ramp to the U.S.101 freeway. The I-380 freeway connecting to North Access Road just south of the Project site also provide full acce via a series of north and southbound on- and off-ramps (see Traffic Figure 2).

CRANE, P.E. • CRANE TRANSPORTATION GROUP The Park SFO existing facility has a total of 1,901 long term pan a garage and 625 in surface parking lots to the north and east of the garage. parking is provided via two side-by-side driveways on the outsid Access Road, about 180 and 270 feet north of the signalized Nort freeway intersection. The southerly driveway connection is used while the northerly driveway is used primarily by outbound traff Appendix Traffic Figure 1  Existing Site Plan). The proposed Project would increase on-site parking from 1,901 up to 3,194 spaces through expansion of the parking garage (on property now used for surfac there would be 2,833 garage spaces and 361 surface parking spaces. Customer and shuttle bus access would remain via the two existing driveways along North A Appendix Traffic Figure 2  Proposed Project Site Plan). IV. EXISTING CIRCULATION SYSTEM OPERATION A. Roadways Direct access to the Project site is provided via North Access Road. It connects to the 380 and U.S.101 freeways via the end of I-380 freeway connection just south of the Project site and via tw intersections with S.

Please see Traffic Figure 4 for existing AM and PM peak hour volumes. It should be noted tthe Park SFO facility had higher volumes at other times during the count (7:08:00 AM & 4:00-5:00 PM), volumes on the local system were significantly lower during these hours. of ambient plus Park SFO traffic (8:00-9:00 AM & 4:45-5:45 PM) were used for analysis purposes in this study.

PROJECT IMPACTS A. SIGNIFICANCE CRITERIA Standards of Significance have been measured based on CEQA, City C/CAG Guideline thresholds. Therefore, project impacts would be 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 would change from Level of Ser A, B, C or D to LOS E or F and total volumes passing through the intersection would least two percent. c.The proposed project would increase total volumes passing through percent or more with signalized operation already at a Base Case E or F. B. Trip Generation The proposed Project will add approximately 1,293 parking spacese Park SFO facility, with parking increased from 1,901 up to 3,194 spaces. Trip generatio been projected utilizing trip rates per parking space developed Wednesday of the week preceding the Labor Day holiday weekend. As shown in Traffic Table 5, trip rates have been developed for shuttle buses as well as cust total trip rate combining both shuttles and customer vehicles co would have resulted in the same number of net new vehicles being Based upon the Park SFO weekday trip rates, the proposed expansi generate 21 inbound and 15 outbound trips during the AM peak houcommute traffic on the local circulation system, with 15 inbound and 32 outbound trips commute traffic on the local circulation system (see Traffic Table 6). As previously detailed, the Park SFO existing operation has its PM commute peak periods offset by about an hour from times of pe circulation system. The times of peak traffic on the local circ poorest operation at all analysis intersections and have therefo even though Park SFO is not at its maximum generation during the conservative Project evaluation and allow for daily variations ir of new customer vehicleshas been increased by 100 percent for analysis purposes. Using this 100 percent safety factor increase in customer vehicles, the proposed increase in parking spaces would be expected to generate 35 inbound and 21 outbound of commute traffic on the local circulation system, with 22 inbo the PM peak hour of commute traffic on the local circulation sys Traffic Table 7). These volumes have been used for analysis purposes. CTG 9/13/12 Park SFO Page 6 MARK D. CRANE, P.E. • CRANE TRANSPORTATION GROUP C. Trip Distribution The increment of traffic from Park SFO expansion was distributed the same pattern as existing Park SFO traffic (see Traffic Figure 7). As shown, the vast majority of customer/employee trafficaccesses the site via the I-380 connection to North Access Road just south of the garage. All inbound shuttles use this route, while travel to the west to S. Airport Boulevard. Overall, there would be a lesser amount of Park SFO expansion traffic expected to travel along S. Airport Boulevard than via I-380 just south of the site. The AM and PM peak hour Project traffic increment is presented i Traffic Figure 8, while 2015 and 2035 with Project AM and PM peak hour volumes are presented in Traffic Figures 9 and 10, respectively. D. Year 2015 Project Intersection Impacts The addition of Park SFO expansion traffic would result in no si intersection near the Project site. Operation of the S. Airport Boulevard intersections with the I-380 ramps would remain LOS A or B during the AM and PM peak hours, w Road/I-380 end of freeway intersection just south of the garage B during both commute peak traffic hours. Project traffic would p increase in delay at the three analysis intersections. E. Year 2035 Project Intersection Impacts The addition of Park SFO expansion traffic would result in no siat any signalized intersection near the Project site. Operation of the S. Airport Boulevard intersections with the I-380 ramps would remain LOS A or B during the AM and PM peak hours, w S. Airport Boulevard at the I-380 westbound on-ramp, which would be operating at an acceptable LOS D during the PM peak hour (with or without the Project). Th380 end of freeway intersection just south of the garage would be operat peak traffic hours. Project traffic would produce only a 0.6 second or less increase three analysis intersections. F. Project Driveway Access Intersections The two project access intersections along North Access Road wou locations along the outside of a 90-degree curve. Sight lines are goo the west (almost 500 feet) and to the south (from 180 to 270 fee I-380 end of freeway signalized intersection). Vehicles making le are infrequently delayed during PM commute conditions due to nor backups extending past the site frontage from a red signal at th-380 end of freeway intersection. However, these backups clear quickly and would be expected to continue to clear relative as area traffic increases. No significant impacts would be expe intersection with proposed expansion traffic. It should be note PM peak hour backups from the I-380 freeway signalized intersection extending in front of the garage driveways ever become a problem, signal timing adjustment reduce these queues. The North Access Road/I-380 end of freeway intersection will be operating at CTG 9/13/12 Park SFO Page 7 MARK D.
