extinct animals, such as mammoth, could be found virtually anywhere in the County, especially along watercourses such as the San Joaquin River and its tributaries (San Joaquin County 2016a). Environmental Impacts and Mitigation Measures a -i) Fault Rupture Hazards. The project site is not on or near a known earthquake fault. The Alquist-Priolo Earthquake Fault Zoning Act, enacted in 1972 and subsequently amended, requires the delineation of Special Studies Zones along known active faults in California. Cities and counties must regulate certain development projects within the zones. The project site is not within an Alquist-Priolo Special Studies Zone (California Geological Survey 2021). The Seismic Hazards Mapping Act, passed in 1990, requires mapping of seismic hazard zones and sets requirements for projects located within such zones. The project site is not within a seismic hazard zone map prepared under the Seismic Hazards Mapping Act (California Geological Survey 2021). Based on this information, the project would have no impact related to fault rupture hazards. a -ii) Seismic Ground Shaking. As noted, the project site may be subject to ground shaking from earthquakes occurring outside the County, which poses a risk of structural damage to the proposed residential buildings. In turn, this could pose a risk to the safety of the occupants. Project development must comply with applicable provisions of the adopted California Building Code, which includes seismic safety provisions that minimize ground shaking impacts. In addition, since the project involves major subdivisions, it is required to prepare a geotechnical report for the County that is intended to identify the presence of geologic hazards such as slope instability, subsidence, adverse soil conditions, seismic hazards, etc., which if not corrected would lead to structural defects (San Joaquin County Code Section 9-905.11). A geotechnical report was prepared for the 2706 Pock Lane site. Appendix D contains a copy of this report. It is expected that the conclusions reached in the geotechnical report would also apply to the 3009 Pock Lane site, given that both sites share the same geological and soil characteristics. The report indicated that the project site could experience seismic ground shaking from several faults in the region (CTE Cal 2021). Implementation of the provisions of the 2019 California Building Code would minimize the risk of structural damage due to potential ground shaking. In addition, the geotechnical report recommended development of the project site in accordance with seismic design criteria specified in the report. Incorporation of these criteria in the design and construction of the proposed development, as required by the mitigation measure described below, would minimize the potential impacts of seismic ground shaking to a level that would be less than significant.
