4.5 PUBLIC UTILITIES This section analyzes the impacts of the proposed project on utility systems, including water,wastewater and recycled water,electricity,and natural gas. The Initial Study prepared for the project determined that impacts related to solid waste services were less than significant and is not required to be analyzed further in this EIR.Information related to this conclusion can be found in the Initial Study included in Appendix D of this EIR. 4.5.1 PHYSICAL SETTING WATER Water Supply Although most of the College Park project site is located within the sphere of influence or service area of the Byron—Bethany Irrigation District(BBID),and an additional 3 acres of the project site are located within the r service area of Plain View Irrigation District(PVID). BBID is a multi-county special district with pre-1914 water rights for reasonable beneficial use of 60,000 acre-feet per annum(afa)of water.BBID diverts water originating in the Sacramento—San Joaquin Delta from the California Aqueduct at the California Department of Water Resource's Intake Channel of the Harvey O. Banks Pumping Plant. BBID's historically highest 5-year average water diversion has been 47,000 afa. In 1996,BBID entered into a Water Services Agreement with Mountain House Community Services District(MHCSD),the domestic water service provider for the project site,to provide 9,413 afa of raw water to MHCSD. As part of the proposed project,the community college area and the 3-acre site mentioned above would be annexed to the BBID.Approval for the annexation from the San Joaquin Local Agency Formation Commission �- (SJLAFCO)would be required before provision of water services from the MHCSD,which receives water from the BBID. In addition,the entire College Park project site would be annexed to the MHCSD service area before the commencement of water services. In addition to BBID's water supply,Trimark Communities(Trimark)owns rights to 2,600 afa of riparian water within the Mountain House Master Plan(MHMP)boundary.Trimark is the developer of both Specific Plan I and II areas of the MHMP. A Water Supply Assessment(WSA)has been prepared for the College Park project as required by California Senate Bill(SB) 610 and is included as Appendix 1. See the WSA for further background information concerning ' the MHMP and College Park water supply. Existing Water Users Existing agricultural water users on the project site include irrigated familand,irrigated pasture, and two dairies. These agricultural water uses would cease under a phased schedule as proposed development replaces these agricultural lands uses.The project site also includes 55 existing residences that receive domestic water supplies from well water. Westside Irrigation District(WSID)owns and utilizes an underground pipeline to deliver water to WSID canals located east of the project site.This pipeline would remain in operation to avoid service disruption in the WSID service area. The majority of existing agricultural land uses on the project site receives water from BBID through irrigation canals.The irrigation canals would be filled or removed as part of project development.
