B.5 Urban Water Management Plan – Implementation
In addition to the analysis and documentation described above, WR P1 subsection (c)(1)(B) requires that all programs and projects included in the UWMP that are locally cost-effective and technically feasible, which reduce reliance on the Delta, are identified, evaluated, and implemented consistent with the implementation schedule. WR P1 (c)(1)(B) states that: (B) Identified, evaluated, and commenced implementation, consistent with the implementation schedule set forth in the Plan, of all programs and projects included in the Plan that are locally cost effective and technically feasible which reduce reliance on the Delta [.] In accordance with Water Code Section 10631(f), water suppliers must include in their UWMP a detailed description of expected future projects and programs that they may implement to increase the amount of water supply available to them in normal and single-dry water years and for a period of drought lasting five consecutive years. The UWMP description must also identify specific projects, include a description of the increase in water supply that is expected to be available from each project, and include an estimate regarding the implementation timeline for each project or program. Sections 2, 5, 6, and 7 of the 2025 UWMP describe implementation plans, efforts, and analyses contributing to reduced reliance on the Delta. Specifically, local projects, programs, and initiatives are highlighted. In addition, Section 3 of Metropolitan’s 2025 UWMP summarizes the implementation plan and continued progress in developing a diversified water portfolio to meet the region’s water needs. Due to the nature of the IRWD, MWDOC, and Metropolitan imported water supplies relationship, IRWD specific actions may not directly affect how much of Metropolitan’s allocation is taken for the region overall. Different blends of water, multiple treatment plant facilities, and the nature of individual distribution system networks complicate these accounting measures, for all member agencies, after the regional level. As a result, the following infeasibility narrative has been provided to better describe an account for these differences. Excerpts from Metropolitan’s UWMP and Appendixes have been included to account for regional actions to reduce reliance on the Delta.
