to supply the proposed project. However, the County does not intend to draw more groundwater from existing wells on the project site to provide for the proposed project. In the memorandum dated March 6, 1996,from Morris Allen, Director of Municipal Utilities for the City of Stockton and provided in Appendix A of theDEIR, the City indicated that the water �— demand for the project can be met by constructing a new well in the project area that is capable of . , producing approximately 2,000 gallons per minute. To mitigate for potential impacts, such as salinity intrusion and movement of the contaminated groundwater plume from Austin Road Landfill, that could occur from this additional ground water pumping and to accommodate the additional demand from the project, Mr. Allen further states that the South Stockton Aqueduct from the Stockton East Water District treatment plant would need to be constructed. Use of surface water !! ' provided by the aqueduct would reduce or eliminate the need for pumping and would avoid impacts related to salinity intrusion and movement of the contaminated groundwater plume. In addition, Mr. Allen states that an update of the South Stockton Water System Master Plan is being initiated to reflect the projected needs of the proposed project. Adoption and E, implementation of this updated plan will ensure that water can be provided and that potential adverse impacts related to salinity intrusion and movement of the contaminated groundwater plume will be avoided. In summary, the City has identified the measures required to meet the demands of the proposed project and to mitigate for potential adverse affects that could potentially result from meeting the demand. This impact is therefore considered less than significant. It is beyond the scope of this program level EIR to provide the environmental review and clearance for projects the City must undertake to safely meet the demands of the project and the obligations of the SWSOM agreement. The environmental effects of these projects will be evaluated in subsequent environmental review. Mitigation Measure None required. Consistency with General Plan and Other Planning Policies The proposed storm drainage improvements comply with San Joaquin County regulations that restrict the peak rate of stormwater runoff from a development to a level that is less than or equal to the preproject flow. Implementation of mitigation measures that require construction contractors to install and operate erosion control and pollutant discharge BMPs complies with General Plan policies for the protection of water quality for existing beneficial uses. Implementation of mitigation } measures related to drainage and flooding will ensure that flooding and drainage hazards will not occur and that facilities essential for emergencies and large public assembly facilities are free from flood inundation. iStockton Metropolitan Airport Project Chapter 5.
