Home Elevations and Buy-Outs

As part of its effort to protect people and property in flood-prone areas, King County manages federal grants to help pay for home elevations as well as property buy-outs.  The King County Flood Control District completed over 53 home elevations of at-risk structures since 2008 and 13 more are currently in progress. Home elevations substantially reduce the threat of future flood damage.  Federal and state grant funding provides up to 90% of the cost, while the homeowner funds the remainder of the elevation costs, with the exception of Severe Repetitive Loss which FEMA covers at 100%.

While home elevations are most appropriate in areas that experience slower moving floodwaters, buyouts are best suited for areas with deep or fast-flowing water. Since its creation, the Flood Control District has acquired 71 at-risk properties and 80 acres, valued at approximately $20 million. The buyouts are voluntary sales—King County pays fair market value for flood-prone properties and structures.  Removing the structure after the buy-out creates a permanent open space that can naturally receive floodwater without threat to lives or property.
