King County’s first complete update of its Flood Management Plan since 2006 capitalizes on the latest climate science to describe how flood risks in urban and coastal communities and along tributary streams are expected to change in the future.

Severe flooding – already the most common natural disaster in King County – is expected to occur more frequently due to climate change. The comprehensive plan will guide investments, strategies, and actions to mitigate increasing flood risk.

The King County Council in September unanimously approved the plan proposed by Executive Dow Constantine.

“Our comprehensive new flood plan – shaped by frontline communities and guided by the latest climate science – outlines strategic actions that will better protect people, homes, and infrastructure,” said Executive Constantine. “Floodwaters don’t recognize borders, so we are expanding our approach to adapt to increasing flood risks in urban and coastal communities, promoting a more equitable, resilient future for our region.” Read more.
