City of Pleasanton—Vineyard Avenue Residential Project Consistency Checklist 15183 Consistency Checklist 116 compliance the General Plan contains policies and programs that would facilitate groundwater recharge by encouraging pervious surfaces in new developments and requiring projects to meet federal, State, regional, and local stormwater requirements, including stormwater infiltration. Therefore, implementation of the Housing Element Update would not conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan and impacts would be less than significant. Proposed Project Analysis and Conclusion Water supplies for the City are managed by Zone 7 of the Alameda County Flood Control and Water Conservation District (Zone 7 Water Agency). Approximately 75 percent of the water supplied by the Zone 7 Water Agency acquires more than 80 percent of its raw water supply from the California State Water Project (SWP), a multi-purpose water storage and delivery system comprised of canals, pipelines, reservoirs, and hydroelectric power facilities that extends more than 705 miles. SWP surface water is treated at the Patterson Pass Water Treatment Plant (PPWTP) and the Del Valle Water Treatment Plant (DVWTP) and is conveyed through a network of Zone 7 Water Agency transmission pipelines to the City’s service areas and other retail customers. Although the proposed project would have the potential to result in an increase in population, the proposed project would be consistent with the type of residential development anticipated for the project site by the City. Therefore, the potential increase in water demand has been accommodated for within the previous analysis. In addition, the project site represents a relatively small area compared to the overall surface area of the San Francisco Bay Basin. Runoff from the proposed impervious surfaces would be directed to the on-site stormwater drainage management facilities and ultimately into the City’s storm drain system. At both locations, runoff water would percolate and recharge the San Francisco Bay Basin. Therefore, any new impervious surfaces associated with the proposed project would not interfere substantially with groundwater recharge within the San Francisco Bay Basin. As discussed in further detail in Section XVIII, Utilities and Service Systems, the proposed project would not result in substantial adverse effects related to groundwater use or water supply. Thus, impacts related to substantially decreasing groundwater supplies or interfering substantially with groundwater recharge were adequately addressed in the Housing Element
