King County, Washington Flood Buyout and Home Elevation Program

Any structure located in a flood-prone area of unincorporated King County, Washington may be eligible for the Flood Buyout or Home Elevation Program grant funds. Structures covered by flood insurance with a history of repetitive flooding and those properties identified as part of a project in the Flood Hazard Management Plan will be more likely to be given priority for available program and grant funds. 

The King County Flood Buyout and Elevation Program involves two approaches to reducing public health and safety risks to residents and property owners living in flood hazard areas of unincorporated King County.

Buyouts involve the voluntary sale to King County of flood-prone properties and structures. According to the King County website: Buyouts are appropriate in areas of deep, fast-moving water, such as those located in the floodway, or those areas threatened by serious bank erosion. Buyouts provide a permanent solution to the risks and damages of repetitive flooding and significantly reduce the public costs associated with county, state and federal agencies' emergency response actions, including evacuations, providing emergency shelters, temporary housing, debris removal and repairs to damaged structures. Buyouts provide the added benefits of improved flood storage and conveyance, and the creation of permanent open space.

Elevation involves assisting property owners with the costs of raising the finished floor of a home above the 100-year elevation, substantially reducing the threat of future damage. This allows the residents to remain on the property, and preserves existing local housing. Elevation projects are more appropriate in areas that experience slower moving floodwaters.

Both programs only involve properties where the owner has previously agreed to participate in the program. No condemnation procedures are used to implement this program.
