Less than significant impact. Water A significant impact may occur if a project would increase water consumption to such a degree that the capacity of facilities currently serving the project site would be exceeded. Water for the City of Pleasanton is supplied by Zone 7, which is predominantly sourced from the South Bay Aqueduct, surface runoff collected in the Del Valle Reservoir, and local groundwater. Zone 7 has a current sustainable water supply of about 86,100 acre-feet per year and manages a local groundwater basin with a capacity of 240,000 acre-feet.111 As a water retailer, the City of Pleasanton provides potable water service to businesses and homes within the City. According to the General Plan Water Element, the current sustainable water supply is 86,100 acre- feet per year. Zone 7 predicts a long-term demand throughout its service area of 82,313 acre-feet in the year 2025, and maintains a 100 percent reliability policy for existing development for the next 20 years through average, single dry, and multiple dry years. Accordingly, estimated demand can be adequately served by existing and forecasted supplies. The UWMP indicates that the City projected total water demand is a total of 20,167 acre-feet per year by 2035 and 21,064 acre-feet per year by 2040.112 Thus, in the long-term, Zone 7 has sufficient water to maintain full water deliveries through General Plan build-out of its customers—including Pleasanton.113 According to the City of Pleasanton’s Water Master Plan Update, the water demand factor for Industrial and Service developments is 0.09 gallons per day (gpd).114 Based on the demand factor, the proposed project would create a demand for 34,295.58 gallons per day, or 38.42 acre-feet per year. This is a conservative estimate based on the highest water demand rate for the land use types that are proposed; therefore, the actual water demand of the proposed project would likely be lower. The estimated water demand would represent less than 0.2 percent of the City’s projected 2040 total water demand, which is a nominal percentage of the City’s projected water demand. The proposed project would be consistent with the General Plan and the City’s 2015 UWMP and would utilize existing water facilities, therefore not requiring construction of new facilities or the expansion of current facilities. Therefore, impacts would be less than significant. Wastewater Treatment A significant impact may occur if a project would increase wastewater generation to such a degree that the capacity of facilities currently serving the project site would be exceeded, or if the RWQCB 111 City of Pleasanton. 2009.
