Saticoy & Wells Community Plan and Code EIRSection 4.14 Utilities and Service Systems4.14 UTILITIES and SERVICE SYSTEMSThis section discusses potential impacts to utilities, including water supply and distribution,wastewater collection and treatment, and energy resources.4.14.1 Settinga. Water Supply. City of Ventura water facilities include water treatment, reservoirs,wells, pump stations, and pipelines. The City provides drinking water to over 109,000 residentsthrough approximately 31,000 water service connections. The City receives its water from threesources: the Ventura River, Lake Casitas, and local groundwater wells. The City owns andoperates 11 wells, three water treatment plants, 23 pump stations, 31 reservoirs, and more than380 miles of distribution pipelines. A portion of Ventura’s water is taken from the VenturaRiver and is stored and pumped from four shallow wells. The City also receives water fromLake Casitas which is operated and treated by the Casitas Municipal Water District (CMWD).Groundwater wells are pumped in the City’s eastside to service the eastern portion of the Cityincluding the Project Area. Only City-generated water diverted from the Ventura River atFoster Park can be used to service the eastern area of the City.There are presently five water sources that provide water to the City water system.• Casitas Municipal Water District• Ventura River Surface Water Intake, Subsurface Water and Wells (Foster Park)• Mound Groundwater Basin• Oxnard Plain Groundwater Basin (Fox Canyon Aquifer)• Santa Paula Groundwater BasinThe City generally uses its water supplies in the following order: (1) Ventura River; (2) LakeCasitas; and (3) groundwater basins. Each of these water sources accounts for approximatelyone-third of the City’s entire water supply. Water is used in this order to maximize the amountof surface water that would otherwise be lost to runoff before using stored groundwater.Figure 4.14-1 shows the locations of the City’s water distribution facilities.Table 4.14-1 summarizes historic and projected water supply from these sources, as detailed inthe 2008 City of Ventura Urban Water Management Plan. The historic delivery values shownrepresent the capacity of available sources. The projected numbers in the table estimateavailable water supply levels under normal, non-drought conditions. Actual water supplylevels in any given year may be higher or lower than these averages.Table 4.14-2 presents historic and projected water production for the City. The City does notcurrently experience water supply shortages and, with the upcoming addition of the SaticoyYard Well, does not anticipate the need for additional supplies within a 20-year horizon. TheSaticoy Yard Well property has been acquired and construction is slated for 2010. The SaticoyYard Well is anticipated to begin production in 2010, with an estimated 75% of designproduction capacity of 2,400 AFY.4.14-1City of Ventura
