4.10 PUBLIC SERVICES AND UTILITIES This section provides an overview of existing public services and utilities for the city of Manteca and the proposed project area, including water supply, solid waste management, electrical service,natural gas service, fire protection, and police service. Because the proposed project would not involve the construction of any new residential structures and would not directly generate more than 14 residents in the project area, it would not require schools or parks;therefore,these resources are not addressed further in this section. Wastewater service is also not addressed in this section because the proposed project is a wastewater service project and the impacts of providing this service are evaluated throughout this DEIR. Stormwater management and drainage impacts are addressed in Section 4.9, "Hydrology and Water Quality."Impacts are evaluated in relation to increased demand for public services associated with the proposed project and actions needed to provide the services and utilities that could potentially lead to physical environmental effects. 4.10.1 ENVIRONMENTAL SETTING WATER SUPPLY Groundwater The City operates a system of groundwater wells interconnected with a transmission and distribution pipeline. Well depths range from 155 feet to 400 feet, and individual capacities of the operating wells range from 380 gallons per minute(gpm)to 2,300 gpm. The groundwater aquifers underlying the city extend to depths in excess of 600 feet, and the strata slope from the hills east of the city downward to the west. Area groundwater levels are influenced by the proximity of the Sacramento—San Joaquin Delta(Delta)channels to the west. Groundwater recharge comes from irrigation of agricultural lands surrounding the city and infiltration from streams flowing west out of the Sierra Nevada. This recharge occurs in areas with permeable materials that allow filtration of water along streams, alluvial fans, and foothill areas;however,none of these features are present within the city, and there are no notable groundwater recharge areas within the city(City of Manteca 2003a). The groundwater basin safe yield was estimated at 1.0 acre-foot per acre per year; however,the basin is currently in a state of groundwater overdraft. The City began receiving surface water from the South County Water Supply Project(SCWSP) in 2005 to reduce the overdraft(City of Manteca 2006). The SCWSP is a joint effort between the Cities of Manteca,Lathrop,Tracy, and Escalon and the South San Joaquin Irrigation District(SSJID)to implement a conjunctive use water system for these cities. The City of Manteca 2005 Urban Water Management Plan recommends a conjunctive use of surface water from the SCWSP and groundwater pumped by the City's groundwater wells. Surface water supply would be used as the base supply and groundwater facilities would be used to meet peak water demands. Surface Water The City is currently participating in the SCWSP. In 1995,the City, along with the Cities of Lathrop, Tracy, and Escalon, entered into an agreement with the SSJID for surface water delivery to these jurisdictions. The SCWSP will deliver up to 11,500 acre-feet per year(AFY)of treated surface water through 2010 from Woodward Reservoir to the turnouts: one on Lathrop Road, east of Union, and the other on West Yosemite Avenue near the wastewater quality control facility(WQCF). A subsequent phase would increase the City's water allocation to 18,500 AFY by 2027(City of Manteca 2003b). Construction of a new water treatment plant at Woodward Reservoir and transmission lines to the City's turnouts were completed in 2005 (City of Manteca 2006). Reclaimed Water Reclaimed water is wastewater that has been collected and highly treated, after human use. Reclaimed water is frequently used to irrigate golf courses,parks, and crops; fill decorative fountains; and fight fires.
