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.

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:
