Riverbank Repair Project
The City of Snoqualmie, with funding from the King County Flood Control District, will repair an existing Snoqualmie River revetment. The repaired revetment will protect properties and structures along the roadway and stabilize a city water main and buried utility infrastructure. Without this repair, continued river erosion will likely cause the road to fail entirely. The project will include installation of wood piling, armor rock, and native vegetation to provide erosion protection, along with removal of invasive plant species growing on this section of the existing revetment.
In the spring of 2015, post-flood inspections revealed damage to two sections of an existing river revetment along the Snoqualmie River at the corner of SE River St and Park Ave SE in downtown Snoqualmie. A revetment is an engineered riverbank protection structure extending from the roadway and into the river. The damages resulted from high river flows, which caused erosion of riverbank armor rocks and exposure of underlying soils.
The Riverbank Repair Project, also known as the Record Office Revetment Project, is located at the intersection of SE River Street and Park Ave SE in downtown Snoqualmie along the Snoqualmie River. (See map below)
