PAGE 9-1 CITY OF SOUTH SAN FRANCISCO HAZARD MITIGATION PLAN
The following paragraph was updated to reflect the Regional Hazard Mitigation plan:
In 2011 ABAG released a Regional Hazard Mitigation plan updating the 2006 HMP. The 2011
plan lists seven earthquake related hazards (fault-related ground surface rupture, seismic
shaking, earthquake induced landslides, liquefaction, dynamic/seismic compaction, lateral
spreading and tsunamis) and four weather related hazards (flooding, landslides, wildfires and
drought). The 2011 Regional HMP was approved by the Federal Emergency Management

Agency (FEMA) in March 2011. Participating local governments, such as the City of South San
Francisco, have prepared annexes to the 2010 plan to specifically explain how the HMP applies
to their jurisdiction. The City prepared their annex in in 2010, releasing it on June 29, 2011.
The annex details previous disaster occurrences, assesses risk and vulnerability, describes
natural hazard exposure associated with land uses, critical facilities and infrastructure within the
City.
Conformity with mitigation measures Geo-3, Geo-3a and Geo-3b would reduce the impact of earthquake
and weather related hazards associated with the entire OPSP, including Phase I project.
Project Impact: less-than-significant.

Appendix and Design Guidelines on March 23, 2011. An update to the plan presenting
Amendments through February 2016 was approved by the City of South San Francisco City
Council on February 10, 2016.
Conformity with mitigation measures Geo-2a, Geo-2b and Geo-2c would reduce the adherence to

South San Francisco Quadrangle, in which the Project site is located.” This information
is incorrect. The project site is not located within the Alquist-Priolo Earthquake Fault
Zone.
Conformity with mitigation measures Geo-1, Geo-2, Geo-3a and Geo-3b should occur as described in the
EIR.

The following paragraph was updated to reflect revisions to the California Building Code (Revised,
2016)
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 2016 CBC.
For earthquake design, Chapter 16 of the 2016 CBC shall be used. To estimate seismic design
parameters, site class estimation is required. Based on the existence of Bay Mud and landfill
material, the site can be classified as Site Class E (soft soils) and/or Site Class D (stiff soils). For
the code level Maximum Considered Earthquake (MCE), the site could experience peak ground
accelerations (PGA) of 0.6g to 0.7g.
Conformity with mitigation measures Geo-3, Geo-3a and Geo-3b as outlined in the original EIR should
occur to address the impact of earthquake and weather related hazards associated with the entire OPSP,
including Phase I project.
Project Impact: less-than-significant.

Some name and distance corrections were made in the table (above). Each of the closest faults is
considered independent seismogenic sources to Oyster Point.
Additional Information
Based on the Fault Activity Map of California (2010) 5, the closest fault to the site is the City
College fault at a distance of about 1 mile to the southwest. The City College fault is a pre-
Quaternary fault and is not considered by CGS as an independent seismogenic source. The
Serra fault is located at a distance of about 3.5 miles to the southwest and is a Holocene fault.
However, this fault and is also not considered by CGS as an independent seismogenic source
and its sesmogenicity has been lumped with the San Andreas Fault. The San Andreas Fault is
the closest independent seismogenic fault and is located approximately 4.5 miles (7.3 kilometers)
southwest of Oyster Point. A major seismic event on these or other nearby faults may cause
substantial ground shaking at the site.
The project site is located in an area characterized by high seismic activity. A number of large
earthquakes have occurred within this area in the past years. Some of the significant nearby
events include the 1906 (M7.9) “Great” San Francisco earthquake, the 1838 (M7) San Francisco
Peninsula earthquake, the 1865 (M6.4) Santa Cruz Mountains earthquake, the 1868 (M6.8)
Hayward earthquake, the 1890 (M6.2) Pajaro Gap earthquake, the 1899 (M5.8) and 1984 (M6.1)
Morgan Hill earthquakes, the 1882 (M5.8) and 1892 (M5.8) Hollister earthquakes, the 1897
(M6.2) Gilroy earthquake, the two 1903 (M5.5) San Jose earthquakes, the 1910 (M5.8)
Watsonville earthquake, two 1926 (M6) Monterey Bay earthquakes, and the 1989 (M6.9) Loma
Prieta earthquake. During the 1989 Loma Prieta earthquake on the San Andreas Fault, several
California Strong Motion Instrumentation Program (CSMIP) stations in the area recorded free-
field horizontal peak ground accelerations ranging from 0.1 to 0.5 g (Thiel Jr., et al., 1990). The
recent South Napa (M6.0) earthquake was located about 65 km to the southwest. The
earthquake occurred along the West Napa fault. A PGA of as large as 1.0 g was recorded at the
Crokett-Carquinez Bridge Geotechnical Array site (Bray et al., 2014).
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.
Project Impact: less-than-significant.
PAGES 9-7 GROUND IMPROVEMENT
Strong Ground Shaking
The text was edited to address new information regarding seismic event probabilities.
A recent publication prepared by the U.S. Geological Survey regarding earthquake probabilities in
the San Francisco Bay Area (Working Group on California Earthquake Probabilities, 2014)6
concludes that there is a 72 percent chance that one of the major faults within the Bay Area will
experience a major (M6.7+) earthquake during the period of 2014-2043. As has been
demonstrated recently by the 1989 (M6.9) Loma Prieta earthquake, the 1994 (M6.7) Northridge
20181427.001A /DOC # Page 5 of 10 August 2017
Copyright 2017 Kleinfelder
earthquake, and the 1995 (M6.9) Kobe earthquake, earthquakes of this magnitude range can
cause severe ground shaking and significant damage to modern urban areas.
Previous EIR stated that “according to a recent study completed by the Working Group of
California Earthquake Probabilities, which assess 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 [Oyster Point Specific Plan] improvements.
Conformity with mitigation measures Geo-2a, -2b and -2c should occur to address strong seismic ground
shaking as well as compliance with applicable regulations and a design-level geotechnical investigation.
This applies to the entire OPSP, including the Phase I Project.
Project Impact: less-than-significant

The majority of OPSP area (71 acres) is located outside of the Federal Emergency
Management Agency (FEMA) 100-year flood hazard zone (FEMA Zone X – Area of
Minimal Flood Zone) as delineated by the current FEMA Flood Insurance Rate Maps
(FIRMs) (2012). The borders of the site which abut the bay waters are within Zone VE
(10 acres), which defines areas in the 100-year flood hazard zone with wave action.
Additionally, the western shorelines are delineated as Zone AE (2 acres), which has a
one percent probability of flooding every year.
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).
Project Impact: None.
PAGE 12-3 REGULATORY SETTING – STATE LAWS AND REGULATIONS
Updated to reflect a new version of the Porter-Cologne Water Quality Act that is available.
The Porter-Cologne Water Quality Control Act, as amended, including statutes 2016,t
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.
PAGE 12-4 REGULATORY SETTING – STATE LAWS AND REGULATIONS
Updated to reflect the project would comply with the most recent version of the Construction
General Permit Order.
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. All construction and SWPPP activity would be in compliance with the
Construction General Permit Order 2009-2009-DWQ, (As amended by 2010-0014-DWQ
and 2012-0006-DWQ).
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.

PAGE 12-11 SIGNIFICANT RISK INVOLVING FLOODING
The following section was updated to reflect the release of the California Climate Science and
Data For Water Resources Management report (2015).
As discussed in the regulatory section above, the recommended sea level rise
assumptions of 24 inches by 2050 and 66 inches by 2100 have been used to assess the
potential for climate-induced sea level rise flooding at the OPSP site (California, South of
Cape Mendocino; DWR 2015). 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

This document provides the Federal Emergency Management Agency’s determination regarding a request for a Letter of Map Revision for the property
described above. Using the information submitted and the effective National Flood Insurance Program (NFIP) map, we determined that the structure(s) on
the property is/are not located in a Coastal High Hazard Area or the SFHA, an area inundated by the flood having a 1-percent chance of being equaled or
exceeded in any given year (base flood). This document revises the effective NFIP map to remove the subject property from the Coastal High Hazard Area
and the SFHA located on the effective NFIP map; therefore, the federal mandatory flood insurance requirement does not apply. However, the lender has
the option to continue the flood insurance requirement to protect its financial risk on the loan. A Preferred Risk Policy (PRP) is available for buildings
located outside the SFHA. Information about the PRP and how one can apply is enclosed.
This determination is based on the flood data presently available. The enclosed documents provide additional information regarding this determination. If
you have any questions about this document, please contact the FEMA Map Information eXchange toll free at 1-877-336-2627 (FEMA MAP) or by letter

ZONE V (This Additional Consideration applies to the preceding property)
A portion of this property, but not the subject of the Determination/Comment Document, is located within a Coastal High
Hazard Area (Zone V, VE or V1-30). Therefore, any future construction or substantial improvement on the property
remains subject to Federal, State/Commonwealth, and local regulations for floodplain management. No construction
using fill for structural support or that may increase flood damage to other property may take place in these areas.
PORTIONS OF THE PROPERTY REMAIN IN THE SFHA (This Additional Consideration
applies to the preceding property)
Portions of this property, but not the subject of the Determination/Comment document, may remain in the Special Flood
Hazard Area. Therefore, any future construction or substantial improvement on the property remains subject to Federal,
State/Commonwealth, and local regulations for floodplain management.
STUDY UNDERWAY (This Additional Consideration applies to the preceding property)
This determination is based on the flood data presently available. However, the Federal Emergency Management Agency
is currently revising the National Flood Insurance Program (NFIP) map for the community. New flood data could be
generated that may affect this property. When the new NFIP map is issued it will supersede this determination. The
Federal requirement for the purchase of flood insurance will then be based on the newly revised NFIP map.
SUPERSEDES OUR PREVIOUS DETERMINATION (This Additional Consideration applies to all properties in
the LOMA DETERMINATION DOCUMENT (REMOVAL))
This Determination Document supersedes our previous determination dated 3/29/2017, for the subject property.
