City of Pleasanton—Vineyard Avenue Residential Project 15183 Consistency Checklist Consistency Checklist 85 that the potential for liquefaction and soil settlement is likely low, but recommended that a confirmation boring be performed as part of the design-level Geotechnical Investigation conducted as required by General Plan policies, including Policies 2 and 5 within the Public Safety Element. In addition, the CBSC, as adopted by the City in Section 20.08.010 of the Pleasanton Municipal Code, provides standards to protect property and public safety by regulating the design and construction of excavations, foundations, building frames, retaining walls, and other building elements, which would further reduce the potential for seismic-related ground failure, including liquefaction. Compliance with the aforementioned uniformly applicable development regulations would ensure that the potential for risks related to liquefaction would be less than significant and the proposed project would not result in any effects that would require further CEQA review for this topic. iv) Seismic-related Ground Failure, Including Landslides Summary of Housing Element Update FEIR As indicated in the Housing Element Update FEIR, aside from Sites 1 (Lester), 22 (Merritt), 23 (Sunol Boulevard), 24 (Sonoma Drive Area), and 26 (St. Augustine), none of the potential sites for rezoning are located within a rainfall-induced landslide hazard zone (Refer to Draft EIR Exhibit 3.6-5). The Housing Element Update FEIR concluded that compliance with California Building Standards Code, 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 protect residents, structures, and infrastructure from potential substantial adverse effects, including the risk of loss, injury or death involving landslides. Therefore, it was concluded that impacts related to landslides at the programmatic level would be less than significant. Proposed Project Analysis and Conclusion Seismically induced landslides are triggered by earthquake ground shaking. The risk of landslide hazard is greatest in areas with steep, unstable slopes. According to the Geotechnical Investigation Report, strong ground shaking during a major earthquake on a nearby fault is likely to be felt at this site, but the site is not mapped in a Zone of Earthquake Induced Landsliding by the State. Based on the relatively flat nature of the site and not being mapped in a Zone of Earthquake Induced Landsliding, the potential for earthquake induced landsliding is low. Therefore, the findings of the Geotechnical
