The Flood Management Plan guides how King County manages flood risks along our rivers, creeks, and shorelines. On June 6, King County Executive Dow Constantine proposed the 2024 King County Flood Management Plan to the Metropolitan King County Council. The Council’s Local Services and Land Use Committee will review the plan and associated legislation and issue a recommendation for full Council action. Please check the Local Services and Land Use Committee webpage for updates about the Council’s review.

The public comment periods for the Draft Flood Plan and associated Environmental Impact Statement are closed. Here is a summary of the public comments received.

Let's plan for flood resilience together

Flooding is our region’s most common natural disaster and is a part of life in King County. Flooding can be devastating to neighborhoods. Floods damage homes, destroy personal property and put lives at risk. Floods also affect access to jobs, stores and schools and can damage community open spaces. Flooding is likely to get more frequent and severe with climate change.

Natural disasters affect people differently, with some having a harder time recovering, or perhaps not recovering at all. Building flood resilience means that we are increasing the ability for people and communities to recover quickly from whatever impacts flooding brings to our doorsteps. Flooding will never disappear in King County, but being prepared can reduce the risks for communities, families, and individuals.

The flood plan guides how we manage flood risks and how the benefits of our efforts are distributed across the county. Information on this site is organized into five sections:

• Flooding and building flood resilience - background information and resources
• Planning for flood resilience - introduction to the plan, the process for updating the plan, and why the plan matters​
• What we've heard from you - a report on the feedback we've recieved so far​
