Planning Commission meeting agenda packet 7-9-25

City of Pleasanton—Vineyard Avenue Residential Project 15183 Consistency Checklist Consistency Checklist 83 and the Vineyard Avenue Corridor Specific Plan (as applicable) would minimize structural damage and minimize the exposure of people to risk of injury or death from structural failure in the event of surface rupture during an earthquake and ensure that impacts would be less than significant. The Housing Element Update FEIR further indicated that the Calaveras, Hayward, and San Andreas Faults 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. Refer to Draft EIR Exhibit 3.6-3. The Housing Element Update FEIR concluded that compliance with CBSC, applicable Municipal Code requirements, as well as goals, policies, and programs included as part of the General Plan, and the Vineyard Avenue Corridor Specific Plan (as applicable) would ensure that future development projects are appropriately investigated in terms of potential seismic hazards and that any new buildings and structures are constructed to withstand strong seismic ground shaking and, therefore, impacts would be less than significant. Proposed Project Analysis and Conclusion According to the Geotechnical Investigation Report, the project site is located in the seismically active San Francisco Bay Area. The seismicity of the area is dominated by the San Andreas, Hayward and Calaveras faults; thus, strong ground shaking during a major earthquake on a nearby fault is likely to be felt at this site. The proposed residences would be constructed in accordance with the requirements of the CBSC, which provides minimum standards to ensure that proposed structures would be designed using sound engineering practices and appropriate engineering standards for the seismic area in which the project site is located. Projects designed in accordance with the CBSC should be able to: 1) resist minor earthquakes without damage; 2) resist moderate earthquakes without structural damage, but with some non-structural damage; and 3) resist major earthquakes without collapse, but with some structural, as well as non-structural, damage. Although conformance with the CBSC does not guarantee that substantial structural damage would not occur in the event of a maximum magnitude earthquake, conformance with the CBSC can reasonably be assumed to ensure that structures would be survivable, allowing occupants to safely evacuate in the event of a major earthquake. As previously discussed, compliance with applicable General Plan policies and the CBSC would ensure impacts related to fault rupture hazards and seismic ground shaking
