City of Pleasanton 2023-2031 (6th Cycle) Housing Element Update CEQA Findings of Fact and Statement of Overriding Considerations 80 FirstCarbon Solutions Https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480022/FOF/21480022 Pleasanton Housing Element FOF.docx reviewed by the City for compliance with the fire protection measures identified in the General Plan and the California Fire Code to ensure that fire risks are not exacerbated (Draft Program EIR, Page 3.16-20–21). Potential Effect Impact WILD-4: Development consistent with the Housing Element Update, rezonings, and General Plan and Specific Plan Amendments would not expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes. (Draft Program EIR, Page 3.16-21). Findings: Less than significant impact. Facts in Support of Findings: Slope instability from wildfire scarring of the landscape can result in more intensive flooding and landslides. New development in the areas identified as very high FHSZ could expose people or structures to wildfire spread. As discussed above, most of the city is not located in a very high FHSZ LRA or SRA. Therefore, the degree of wildland fire hazard, including downslope or downstream flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes, would not substantially change with adoption of the Housing Element Update, and current hazards would not significantly increase. All future development on the potential sites for housing would be subject to the rules and regulations of the Municipal Code and the General Plan regarding development on unstable geologic soils and controlling stormwater runoff during and after construction. Specific policies related to the prevention of flooding, landslides, and drainage changes include Program 5.1 and 5.2, which requires site-specific soils study and/or site-specific geologic and/or geotechnical engineering studies for all individual development approval on the potential sites for housing and the recommendations provided by the studies would be incorporated into project design as required by Program 2.2. Policy 6 restricts new development of sites with structures intended for human occupancy in any landslide prone or unstable areas. The applicable programs included in this policy (Programs 6.1, 6.2, 6.3, 6.4, 6.5, and 6.6) prohibit new development of sites with structures intended for human occupancy in any landslide prone areas unless the landslide risk can be eliminated and requires engineering studies to demonstrate that structures in landslide prone areas would sustain no more damage related to slope instabilities than damage sustainable by similar buildings within the city. The programs also require developments to include design features and mitigation to reduce damage associated with seismic-related ground failure and the establishment of Geologic Hazard Abatement Districts (GHADs) to ensure ongoing monitoring and maintenance of slopes and drainage facilities occur. Combined with the review of architectural and development plans by the LPFD, these policies provide additional proactive measures to refine and enhance the resiliency of the city, as well as strengthening the City’s review of new applications for development to ensure that potential exposure to secondary wildland fire hazards are not exacerbated (Draft Program EIR, Page 3.16-21–22). Potential Effect Cumulative Impact: Cumulative impacts related to wildfire would be less than significant. (Draft Program EIR, Page 3.16-23).
