Boulevard.These pipelines are of sufficient size to serve the entire Mountain House development area. _ Extensions to the pipelines into the College Park project site are planned for Central Parkway and DeAnza Boulevard to form a connecting loop (see Appendix K for the Pipeline Risk Analysis report). 4.5.2 REGULATORY SETTING WATER Federal Regulations The proposed project is not located or in the vicinity of federal lands, and there are no federal land-use or farmland conversion regulations applicable to the project. State Regulations Senate Bills 610 and 221 SB 610(Section 21151.9 of the Public Resources Code and Section 10910 et seq.of the Water Code)requires the preparation of"water supply assessments"for large developments (e.g.,more than 500 dwelling units or noresidential equivalent), such as the College Park project.These assessments,prepared by"public water systems"responsible for service project areas, address whether there are adequate existing or projected water supplies available to serve such proposed projects,in addition to urban and agricultural demands and other anticipated development in the service area in which the project is located.Where a WSA concludes that insufficient supplies are available, the WSA must lay out steps that would be required to obtain the necessary supply.The content requirements for the assessment include,but are not limited to, identification of the existing and future water suppliers and quantification of water demand and supply by source in 5-year increments over a 20-year projection.This information must be provided for average normal, single-dry, and multiple-dry years. The absence of an adequate current water supply does not preclude project approval,but does require a lead agency to address a water supply shortfall in its project approval findings. An SB 610 WSA has been prepared for the College Park project(West Yost&Associates 2004).The WSA is included as Appendix I. The conclusions of the WSA are summarized in the"Impact Analysis"portion of this section. If the College Park project is approved, additional complementary statutory requirements, created by 2001 legislation known as SB 221 (Goverment Code Section 66473.7)would apply to the approval of tentative subdivision maps for more than 500 residential dwelling units.This statute requires cities and counties to include, as a condition of approval of such Tentative Maps,the preparation of a water supply verification.The verification is intended to demonstrate that there is a sufficient water supply for the newly created residential lots.The statute demes sufficient water supply as the total water supplies available during normal, single-dry, and multiple-dry years within a 20-year projection that will meet the projected demand associated with the proposed subdivision, in addition to existing and planned future uses,including,but not limited to, agricultural and industrial uses. A number of factors must be considered in determining the sufficiency of projected supplies, including: r- The availability of water supplies over a historical record of at least 20 years; The applicability of an urban water shortage contingency analysis that includes action to be undertaken by the public water system in response to water supply shortages; The reduction in water supply allocated to a specific water-use sector minder a resolution or ordinance adopted, or a contract entered into,by the public water system,as long as that resolution,ordinance,or contract does College Park at Mountain House Specific Plan III Draft EIR EDAW San Joaquin County 4.5-7 Public Utilities
