City of Pleasanton 2023-2031 (6th Cycle) Housing Element Update CEQA Findings of Fact and Statement of Overriding Considerations 28 FirstCarbon Solutions Https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480022/FOF/21480022 Pleasanton Housing Element FOF.docx Goal 2 focuses on minimizing risks to lives and property due to geologic hazards. Policy 5 requires investigation of potential for geologic hazards during the development review process and implementation of soils engineering and construction standards to minimize potential dangers from earthquakes. The applicable programs included in Policy 5 (Program 5.1, 5.2, 5.3, 5.4, and 5.5) require site-specific soils study prior to the issuance of building permits and prior to the approval of final improvement plans and a site-specific geologic and/or geotechnical engineering study where there is risk of surface fault rupture, bank failures, rock falls, landslides, and for areas with slopes equal to greater than 20 percent. They also require certain technical review of geotechnical studies to ensure the recommendations and mitigations provided in those studies are incorporated into project design. Accordingly, as required by Policy 2, a site-specific soils, geologic, and/or geotechnical engineering studies would be required prior to development approval of structures for human occupancy for any project proposed within Site 22 (MerrittMerritt), and, as required by Program 5.1 and 5.2, site-specific soils study and/or site-specific geologic and/or geotechnical engineering studies would be required for all individual development approval on the potential sites for rezoning and the recommendations provided by the studies would be incorporated into project design as required by Program 2.2. Site 27 (PUSD-Vineyard) is within the Vineyard Avenue Corridor Specific Plan Area, and it would be required to abide by the applicable geological requirements related to construction. Impacts related to surface fault rupture would be reduced by compliance with California Building Standards Code (CBC) engineering design and construction measures. Foundations and other structural support features would be designed to resist or absorb damaging forces from strong ground shaking and surface fault rupture. Chapter 20.08 of the Municipal Code incorporates the most recent CBC. The Pleasanton City Building and Safety Inspection Division reviews plans and applications for site clearance, grading, and building permits to ensure compliance with Chapter 20.08 (California Building Standards Code) and imposes requirements for revisions where needed to ensure that new or significantly remodeled structures are constructed in compliance with the CBC, and reflect any additional measures deemed appropriate. Permit issuance would be based upon satisfactory completion of any identified applicable measures. Additionally, Chapter 17.12 (Geologic Hazards) requires the consideration of geologic hazards when considering applications and permits for new real estate developments or structures for human occupancy Strong Seismic Ground Shaking: The Calaveras, Hayward, and San Andreas Fault are most likely to produce the greatest level of ground shaking at the potential sites for rezoning. “Violent” or “severe to violent” ground shaking is expected to occur throughout the city including at several of the potential sites for rezoning. As discussed above, Chapter 5 of the General Plan, Public Safety Element, includes policies and programs to protect residents within the city and surrounding areas from seismically induced hazards associated with strong seismic ground shaking, including Goal 1, Policy 1, Policy 2 (including, but not limited to, Program 2.1, 2.2, 2.3, 2.5, and 2.6), Policy 5 (including Program 5.1, 5.2, 5.3, 5.4, and 5.5). Site 27 (PUSD-Vineyard) is within the Vineyard Avenue Corridor Specific Plan Area, and it would be required to abide by the applicable geological requirements related to construction. Potential structural damage and exposure of people to risk of injury or death from structural failure associated with strong seismic ground shaking would be reduced by compliance with CBC
