ITEM 23 ATTACHMENT 1 - CEQA Checklist

City of Pleasanton—Merritt Property Project Consistency Checklist 15183 Consistency Checklist 204 d) Flooding and Landslide Hazards Due To Post-fire Slope Instability/Drainage Changes Would the project: If located in or near State Responsibility Areas or lands classified as Very High Fire Hazard Severity Zones, 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? Summary of Housing Element Update FEIR As noted under Impact XIX(a) above, most of the City is not located in a VHFHSZ 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. As described under Impact XIX(b) above, the Housing Element Update FEIR indicated new development in the areas identified as VHFHSZ could expose people or structures to wildfire spread. All future development on the housing sites 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. 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. Thus, the Housing Element Update FEIR concluded that impacts would be less than significant. Proposed Project Analysis and Conclusion The southern portion of the project site is within a Moderate FHSZ with the easternmost portion of the site mapped as a VHFHSZ SRA. Additionally, the northern portion of the project site is mapped as a VHFHSZ LRA (Exhibit 7). As described under Impact VII(c) of Geology, Seismicity, and Soils, the project site is flat and is not at risk for landslides because the project site generally consists of competent soils and bedrock. As such, the project site would not be at risk of downslope flooding. Furthermore, Section X, Hydrology and
