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.

Funding for the Flood Control District comes from a county-wide property levy of 9.2 cents per $1,000 assessed value. This amounts to $38 per year on a $416,000 home. The levy raises roughly $58.5 million a year. This funding dramatically increases the number of projects that can be completed each year. The additional local funding also enhances the District's ability to receive federal and state matching funds.

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.
