Plans shall be prepared for facilities that use, store, or handle hazardous materials in quantities exceeding thresholds established by regulatory agencies to assure safety in handling of such materials under normal and emergency conditions. Specific Plan, p. 78-79; DEIR, pp. 84-85. Hydroloey. Draina¢e, and Water Quality 1. Potential to contribute to flooding risk onsite and downstream of the Project Findin .The City finds that the following mitigation measures are feasible and have been incorporated into the Specific Plan, thereby mitigating the impacts to a less-than-significant level: • The detention basins on the Phase II Specific Plan site have been sized to accommodate anticipated development. With the adoption of the Bernal Property Phase II Specific Plan, the City will revalidate the design assumptions to confirm the basin sizes. • All drainage components will be designed in compliance with City of Pleasanton standards, and the Department of Public Works will review grading and drainage plans to assure compliance. • All Specific Plan projects covered by Provision C.3.f of the County NPDES Permit shall fully comply with permit requirements. Specific Plan, p. 74-76; DEIR, pp. 87-89; Responses to Comments, p. 30. 2. Potential degradation of surface water quality from runoff during construction and operation of the Project Findin>;. The City finds that the following mitigation measures are feasible and have been incorporated into the Specific Plan, thereby mitigating the impact to a less-than-significant level: • A Storm Water Pollution Prevention Plan (SWPPP) is to be prepared and implemented to reduce potential impacts on surface water quality through the construction period of the Project. • All Specific Plan projects covered by Provision C.3.f of the County NPDES Permit shall fully comply with permit requirements. Specific Plan, p. 75; DEIR, pp. 89-90. 3. Potential degradation of groundwater resources Findin .The City finds that the following mitigation measures are feasible and have been incorporated into the Specific Plan, thereby mitigating the impact to a less-than-significant level: The design of any modification to the stormwater detention basins shall maintain an adequate distance between the basin floor and the underlying groundwater (generally, 10 feet of unsaturated sediments) or comply with Bernal Property Phase II Specific Plan and Bernal Community Park Master Plan Environmental Impact Report Findings and Statement of Overriding Considerations Page 16 of 24
