4.5.4 IMPACTS ANALYSIS ANALYSIS METHODOLOGY _ The evaluation of utilities systems is based on comparisons of existing and planned capacities of domestic water, irrigation water, wastewater,electricity, and natural gas systems with estimated post-development demands for these utilities. Information regarding existing and planned capacities is based on the College Park at Mountain House Specific Plan III(EDAW 2004),Mountain House Community Services District Specific Plan III ` Amendments to the Sanitary Sewer Collection System Study(MacKay& Somps 2004a),Mountain House Master Plan Final EIR(1994),Delta College EIR(2003),and Technical Memorandum regarding Mountain House Specific Plan III Utilities(MacKay& Somps 2004b).These documents are available for review during normal business hours at the San Joaquin County Community Development Department, 1810 East Hazelton Avenue, Stockton,California 95205. IMPACTS AND MITIGATION MEASURES 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(IS)prepared for the proposed project found that little or no groundwater would be used for the project's water supply,and the project would not substantially deplete groundwater supplies.Along with this, development of the proposed project would result in less than 0.2%of the Tracy groundwater subbasin being covered with impervious surfaces and would result in a negligible reduction in infiltration within the subbasin as a whole.Therefore,the project would not interfere substantially with groundwater recharge.Based on information related to solid waste disposal capacities of the San Joaquin County South County Refuse Service Area,and because the proposed project would comply with all applicable federal, state,and local statutes and regulations related to solid waste,adequate permitted landfill capacity exists to accommodate the proposed project.Therefore,in accordance with Section 15063(b)(1)(C)of the State CEQA Guidelines,the potential for the proposed project to interfere with groundwater water recharge and impact solid waste disposal services are not evaluated further in this EIR. See the IS(Appendix D of this Draft EIR) for further discussion. " IMPACT Public Utilities—Demand for Water Supply. The proposed project would create a demand for water from 4.5-1 BBID that, when added to the existing and future water demand for the balance of the MHMP area at buildout(2025), would exceed existing contracted capacity according to the College Park SB 610 WSA. However, subsequent to the preparation of the SB 610 WSA, a non-potable irrigation water system was added to the proposed project that would avoid this projected water supply shortfall. Wdh implementation of this system, adequate water supply would be available to serve the proposed project.A less-than- significant impact would occur. Through a Water Services Agreement,MHCSD has a contract with BBID to provide 9,413 afa of raw water to MHCSD which is the domestic water service provider for the MHMP area,including the project site.According to MHCSD's WSMP,which calculates the average daily water demand for both domestic water and irrigation water generated by total development in the MHMP area,the average daily water demand would be 9,849 afa at MHMP buildout.The difference between MHCSD's contracted supply of 9,413 afa and the total demand of 9,849 ' afa would be 436 afa.This shortfall would be met with Trimark's existing rights to 2,600 afa of riparian water which would be used to meet irrigation needs.As a result,the MHMP EIR determined that there would be sufficient total water supply to serve buildout under the MHMP. The proposed College Park project would create a projected water demand of 1.45 mgd(MacKay& Somps 2004b).This demand would be below the demand of 1.52 mgd estimated for the project in the MHMP(MacKay & Somps 2004b).Table 4.5-1 below shows the projected water demand for the project compared to that associated with buildout of the College Park project site under the MHMP.As shown in Table 4.5-1,the project would demand approximately 0.077 mgd less water than estimated under the MHMP.
