Planning Flood Risk Management in the Lower Green River Corridor

The King County Flood Control District (District) completed a Programmatic Environmental Impact Statement (PEIS) on April 30, 2024. The PEIS evaluated different approaches for reducing flood risks in the Lower Green River Corridor while delivering multiple community benefits. The PEIS reflects collaboration with Tribes, jurisdictions, agencies, interested parties, and the public.

Building on the PEIS, the District is now developing a long-term Flood Hazard Management Plan (Plan) and Capital Investment Strategy (CIS) to guide future investments that will help protect people, property, and the environment in this vital area.

Visit the District’s Lower Green River Corridor Flood Hazard Management Plan webpage (KCFCDLowerGreenRiverPlan) to view the PEIS; learn more about the Plan, CIS, and how to participate in the planning process; and contact the District with your questions.
