City of Pleasanton—Villages at the Quarry Project <br />15183 Consistency Checklist Consistency Checklist <br /> <br /> <br /> 147 <br />connections to the municipal water supply, which could potentially increase <br />demand for groundwater supplies. <br />The Housing Element Update FEIR concluded that future development <br />consistent with the Housing Element Update would be required to comply <br />with requirements of the Municipal Code and General Plan policies and <br />actions related to maximizing infiltration and rainwater retention and <br />requiring the identification of an adequate water supply. Therefore, future <br />development consistent with the Housing Element Update would not <br />substantially interfere with groundwater recharge or impede groundwater <br />management of the basin, and impacts would be less than significant. <br />Proposed Project Analysis and Conclusion <br />According to the Preliminary Geotechnical Report (Appendix E) prepared for <br />the proposed project, no groundwater was encountered during subsurface <br />explorations performed at the project site. However, previous subsurface <br />explorations encountered groundwater between 50 and 60 feet below <br />ground surface (BGS).26 <br />The proposed project would include the addition of 1,348,814 square feet of <br />new impervious surface. <br />As detailed in the Preliminary Stormwater Control Plan, the proposed project <br />is required to treat 100 percent of the runoff from impervious surfaces within <br />the project site; this would be achieved by directing all runoff (i.e., roof, <br />street, and driveway) to six proposed bioretention basins located throughout <br />the project site. These proposed project design features would help to <br />reduce the impact to groundwater recharge and sustainable basin <br />management. <br />The proposed project would be required to comply with requirements of the <br />Municipal Code and General Plan policies and actions related to maximizing <br />infiltration and rainwater retention and requiring the identification of an <br />adequate water supply. <br />Therefore, there are no environmental effects that are peculiar to the <br />proposed project. The proposed project would not result in a new or more <br />severe adverse impact that was not previously identified in the Housing <br />Element Update FEIR. <br /> <br />26 ENGEO Incorporated (ENGEO). 2024.
