Metropolitan Airport property. Under the terms of the agreement, the`City is to provide the water"' `service, but the County, with establishment of a new County Service Area, will be responsible for constructing; operating, and maintaining distribution facilities on the airport property. IL As indicated in the letter from Morris Allen,director of Municipal Utilities, City of Stockton, in a memorandum dated March 6, 1996, and provided in Appendix A of the DEIR, the City has indicated that the water demand for the project can be met by constructing a new well in the project area capable of producing approximately 2,000 gallons per minute. To mitigate for potential impacts, suchras salinity intrusion and movement of the contaminated groundwater plume from Austin Road Landfill,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. In addition, he states that an update of the South Stockton Water System Master Plan is being initiated to reflect the projected needs of the project. In summary, the City has identified the 'measures required to meet the demands of the proposed project and to mitigate for potential adverse impacts that could result from meeting the demand. It is beyond the scope of this program level EIR to provide the environmental review and clearance for projects that 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. Table .1-1, page 3-13, Impact PS-4 on page 10-6, and page 5-11 of the DEIR have been modified to reflect this information. Response to Comment 1-6. Refer to Response to Comment 1-5. As discussed in Response to Comment 1-5,,the City has identified measures to avoid adverse effects related to the contaminated groundwater plume. It is beyond the scope of this program level EIR to provide the environmental review and clearance for projects that the City must undertake to safely meet demands of the project and the obligations of the SWSOM agreement. The environmental effects of these projects will be evaluated in subsequent environmental review. Table 1-1, page 3-13, Impact PS-4 on page 10-6, and page 5-11 of the DEIR have been modified to reflect this information. FResponse to Comment 1-7. Page 3-4 of the DEIR has been modified to state that the detention basin will be constructed within the Stockton city limits and that storm utility facilities constructed within the City must comply with City and San Joaquin County standards and be approved by the City and the County's Department of Public Works. k Response to Comment 1-8. Proposed drainage for the project site is discussed in the Overall Drainage Studies Report, which is part of the Stockton Metropolitan Airport Master Plan. On pages 5-6 and'5-7,the DEIR discusses drainage based on the results of the Overall Drainage Studies VReport. Terminal drainage for the project site goes to Mansville Ditch and Weber Slough. With full development of the airport, no increase in the rate of stormwater discharge into Weber Slough or ti Mansville Ditch downstream from the airport will occur. The DEIR recognizes and discusses the fact that Mansville Ditch and Weber Slough have inadequate capacity to accommodate flows and identifies a significant impact related to stormwater drainage. Mitigation Measure DW-1, identified I on page 5-7 of the DEIR,requires the development and implementation of a comprehensive drainage 5 Stockton Metropolitan Airport Project Section I.
