The bill amends several sections of the Revised Code of Washington (RCW) to extend the water supply milestone for the Yakima River Basin Integrated Plan to 2035. Key changes include the adjustment of the deadline for securing permits and funding for water supply facilities from June 30, 2025, to June 30, 2035, and the specification that these facilities must provide at least 214,000 acre-feet of water for both instream and out-of-stream uses. Additionally, the bill modifies the review process for water supply projects exceeding $100 million, ensuring that the Washington Water Research Center evaluates the cost-benefit analysis of such projects.

Further amendments include the requirement for the Department of Ecology to prepare a comprehensive cost estimate and financing plan for the integrated plan's implementation, with updates every two years. The bill also allows the Department of Natural Resources to purchase land for the community forest trust without adhering to certain prerequisites, provided that the land is managed in consultation with the Department of Fish and Wildlife. The transitional management plan for the acquired land must align with the integrated plan's principles, and the bill establishes a community advisory committee to oversee land management. The act is declared necessary for the immediate preservation of public peace, health, or safety, and is set to take effect on June 30, 2025.
