Throughout Washington, rain often brings risk: Flood-prone communities routinely face threats to homes and infrastructure. Natural resources like floodplains are important for absorbing and distributing rainfall, but development has weakened their power.
We’re working with communities to prepare and plan for flood threats. One important first step is defining the risk to flood-prone communities, as the maps below illustrate. We’re working to find a balance so that, as Washington’s populations grow, floodplains can sustain our communities, economies and environment.

This map highlights the five most flood prone counties in Washington:
