Riverbank Repair Project

Project Info Sheet

RFQ Riverbank Revetment Project

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 City of Snoqualmie, with funding from the King County Flood Control District, is planning to 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.

Project Location


The Riverbank Repair Project, also known as the Record Office Revetment Project, will be located at the intersection of SE River Street and Park Ave SE in downtown Snoqualmie along the Snoqualmie River. 

Construction Timeline


Approximately Mid-July 2021 through November 2021

Road Closure

Roadway in the following sections will be closed 24/7 in both directions throughout the project. 

  • SE River St from Falls Ave SE to Park Ave SE
  • Park Ave SE from SE River St to SE Newton St
Residents along Park Ave SE will be able to access their properties from the alley behind their homes. Parking will be available on side streets. 

Noise


Noise will include pile driving, general construction activities, equipment operation, and truck traffic to deliver materials, supplies, and equipment to the project site.

Structural Impacts


Construction activities are not anticipated to create significant structural impacts or property damage. Some minor impacts may occur and will be restored following the project. Pile driving operations could create ground vibration, but this is expected to be minor and will not likely cause damage to nearby structures.
