King County has experienced 12 federally declared flood disasters since 1990.

Protecting citizens and property from injury and damage by natural disasters is a fundamental role of government. In 2007, the King County Flood Control District was established to provide a proactive, regional approach to flooding as well as funding to improve the county's nearly 500 aging and inadequate flood protection facilities.
All nine members of the King County Council oversee the Flood Control District as a Board of Supervisors. A 15-member Advisory Committee made up of local government officials and citizens provides advice to the board. The King County Department of Natural Resources and Parks carries out the approved flood protection projects and programs.
