A WDODARa &CURRAN supplies for the net increase in demand of the Project over the next 20 years, in addition to existing and planned future uses. 1.3 Urban Water Management Plan and Other Resources California Water Code 10910(c) (1) The city or county, at the time it makes the determination required under Section 21080.1 of the Public Resources Code, shall request each public water system identified pursuant to subdivision (b) to determine whether the projected water demand associated with a proposed project was included as part of the most recently adopted urban water management plan adopted pursuant to Part 2.6 (commencing with Section 10610). (2) If the projected water demand associated with the proposed project was accounted for in the most recently adopted urban wafer management plan, the public water system may incorporate the requested information from the urban water management plan in preparing the elements of the assessment required to comply with subdivisions(d), (e), (t), and(g). (3) If the projected water demand associated with the proposed project was not accounted for in the most recently adopted urban water management plan, or the public water system has no urban water management plan, the water supply assessment for the project shall include a discussion with regard to whether the public water system's total projected water supplies available during normal, single dry, and multiple dry water years during a 20-year projection will meet the projected water demand associated with the proposed project, in addition to the public water system's existing and planned future uses, including agricultural and manufacturing uses. In accordance with the California Urban Water Management Planning Act(Act),the City adopted its 2015 Urban Water Management Plan (UWMP) in October 2017. As required by the Act, the 2015 UWMP includes an assessment of projected water supplies required to meet future demands. The projected water demand associated with the Project was not accounted for in the most recently adopted UWMP, thus CWC Section 10910(c)(3) applies and this water supply assessment includes a discussion of whether the public water system's total projected water supplies available during normal,single dry,and multiple dry water years during a 20-year projection period will meet the projected water demand associated with the Project in addition to the public water system's existing and planned future uses. In December 2019, the City prepared a Water System Master Plan (2019 WSMP) Update. Developed as part of the City's Integrated Water Resources Master Plan(IWRMP) Update, the WSMP provides a comprehensive update to the City's Potable Water System, Wastewater System, and Recycled WSMPs. This WSMP focused on development of water demand unit factors and projections, hydraulic assessment of the City's existing water infrastructure and key planned improvements, and development of recommended water system capital improvement projects. Information from the 2019 WSMP is the initial basis for the elements of this WSA addressing demands and supplies from all sources of water as it contains new information regarding groundwater supplies and SSJID reliability, updated from the 2015 UWMP. The City's 2015 UWMP water demand projections and the Project water demand projections were the original basis for the demand assessment in this WSA, but they have been updated by the City. The City is currently in the process of developing its 2020 UWMP and prepared revised demand projections in August 2020, which are presented in Appendix B of this document. Those revised projections are adopted as part of this WSA. The City's 2019 WSMP single- and multiple-dry year supply analysis and the SSJID 2015 UWMP were the original sources for the dry year evaluations of this WSA.The City's single-and multiple-dry year supply estimates too have been updated for this WSA to reflect the removal of certain City groundwater wells as anticipated future groundwater supplies.
