Circle River Ranch Flood Risk Reduction Project
In Winter 2021, the King County Flood Control District (District) selected a preferred alternative with combined features from Alternatives 1 and 2 to move forward through design and construction. Technical analysis and public feedback informed the District’s decision A summary of the public comments that were received is available.

About the Selected Alternative
The selected alternative will repair the damage to the upstream end of the existing revetment through construction of a partially buried setback revetment, approximately the same length as the damaged area. The buried setback revetment will provide erosion protection to the properties downstream from the repair site, behind the damaged revetment. The selected alternative includes acquiring at-risk homes from willing sellers which will permanently reduce risks by getting people out of harm’s way.
The Circle River Ranch neighborhood is located along the right bank of the South Fork Snoqualmie River, just downstream from the City of North Bend. The damaged area to be repaired is shown in the image below.
