Record Office revetment repair, Snoqualmie, WA


King County, in close cooperation with the City of Snoqualmie, is constructing a repair to the Record Office Revetment on the left bank of the Snoqualmie River along Park Avenue SE within the City of Snoqualmie. The Record Office Revetment protects residences along the road and a city water main located under the road shoulder.

Damages to two sections of the Record Office Revetment were identified during post flood inspections in the Spring of 2012. The damages resulted from scour due to high flows, which caused loss of river bank armor along the toe and face of the revetment and exposure of the underlying soils.

The repair to a 135-foot long portion that includes both damaged sections will address the immediate risks of continued erosion to the facility and the potential for short-term impacts to city infrastructure. The repair includes installation of rock riprap and native vegetation to provide erosion protection, along with removal of an infestation of knotweed – a noxious weed – growing on this section of the revetment.

Project goals

Reduce risks to Park Avenue Southeast and its residences and a City of Snoqualmie water main by protecting the damaged revetment from further erosion.

Project timeline

Construction started on October 24, 2012, and is anticipated to be complete by November 20, 2012. Park Avenue SE will remain open during this time period; however, motorists should proceed cautiously due to trucks entering and leaving the site.
