The King County Flood Control District was established in April, 2007 by ordinance 15728 of the Metropolitan King County Council to protect public health and safety, regional economic centers, public and private properties and transportation corridors. The newly created district will be instrumental in addressing the backlog of maintenance and repairs to levees and revetments, acquiring repetitive loss properties and other at-risk floodplain properties, and improving countywide flood warning and flood prediction capacity.

Overarching countywide strategies and objectives include:

  • Improving levee protection through major commercial, industrial and residential areas,
  • Improving flood water conveyance and capacity,
  • Reducing hazards by removing flood, erosion, and landslide prone residential structures,
  • Providing safe access to homes and businesses by protecting key transportation routes,
  • Minimizing creation of new risks to public safety from development pressure.

Funding Opportunities

The King County Flood Control District (KCFCD) is an independent special purpose district of the State of Washington, as authorized by Chapter 86.15 of the Revised Code of Washington (RCW). RCW 86.15 authorizes the King County Council to be the District’s board of supervisors, the governing body for the KCFCD. In addition, the District’s governance structure is comprised of an advisory committee, King County staff, and basin technical committees.
