City of Pleasanton Pleasanton Climate Action Plan 2.0 or telecommunications utilities. However, projects resulting from implementation of the CAP 2.0 could include redevelopment and/or restructuring of electricity and natural gas power facilities and infrastructure, as well as new local renewable energy generation and storage and green stormwater infrastructure projects. Potential impacts related to these strategies are discussed further below. Water Supply Facilities/Infrastructure The City of Pleasanton is the retail water supplier for development within the City. Pleasanton obtains its municipal water supply from a mix of local groundwater wells and Zone 7 of the Alameda County Flood Control and Water Conservation District (Zone 7). According to the Pleasanton Urban Water Management Plan (UWMP), the City currently purchases approximately 80 percent of its water from Zone 7 and the remaining 20 percent is produced from the City's groundwater wells. Zone 7 uses a combination of water supplies to meet water demand which include imported surface water from the State Water Project, imported surface water transferred from the Byron Bethany Irrigation District, local surface water runoff captured in Del Valle Reservoir, and local groundwater. The City's distribution system consists of 327 miles of pipelines and 22,369 water service connections. There are 14 pump stations, 22 water storage reservoirs, one hydropneumatics tank, and approximately 51,500 linear feet of recycled water pipeline.94 The City addresses issues of water supply in the Pleasanton UWMP, which is a long-range planning document used to assess current and projected water usage, water supply planning, and conservation and recycling efforts. According to the UWMP, the City has analyzed three different hydrological conditions to determine the reliability of water supplies: average/normal water year, single dry water year, and multiple, dry water year periods. The UWMP indicates that water supplies under the three hydrological conditions will be sufficient to meet demand through 2045. In addition, the UWMP includes a Water Shortage Contingency Plan.95 CAP 2.0 Action P15 seeks to decrease community water use by promoting water efficiency retrofits, sustainable landscaping, and efficient landscaping irrigation. In addition, CAP 2.0 Actions S8 and P13 would increase green stormwater management infrastructure and the planting of urban trees, which would increase permeable surfaces throughout the City, improving water infiltration and groundwater recharge. Furthermore, the CAP 2.0 would not result in new land uses, such as increased residential or commercial development, that would contribute to an increase in water use compared to existing conditions or that would require relocation or construction of new water infrastructure. Therefore, the CAP 2.0 would have no impact related to the need for construction or expansion of water supply facilities and infrastructure. Wastewater Treatment Facilities/Infrastructure The City of Pleasanton collects wastewater within Pleasanton City limits as well as wastewater from the Castlewood Area of Alameda County. The sanitary sewer system currently serves an area of approximately 24 square miles and consists of 250 miles of gravity sewers, approximately 25,192 feet of force main, and ten pump stations.96 Sewage treatment for the collected wastewater is 94 Pleasanton, City of. 2021. 2020 Urban Water Management Plan.
