📋 Tender Overview
Project Limits: Milepost 1.46 to 1.50
Federal Classification: Rural Local Access (09)
Project Description: This project will replace the existing
triple box culvert with a bridge to meet current fish passage
requirements.
Basis for Project: The existing triple box culvert is reaching
the end of its useful life and has been identified as a fish barrier.
In addition this area floods during large events.
Environmental/Safety Considerations: This culvert presents a fish blockage so its removal will provide
access to upstream habitat to Chinook, Coho, Steelhead, resident Trout and other resident aquatic species. As
with any in-stream work it will be performed during the appropriate fish window and all impacts for wetland
disturbance will be mitigated.
The existing culvert is at the end of its useful life and if not replaced could collapse damaging the roadway
surface or if complete collapse occurs creating a sinkhole large enough to damage a vehicle and/or block the
roadway.
Funding Sources: This project will be funded with local road funds and potentially a Washington State
Recreation and Conservation Office, Fish Barrier Removal Board Grant Funding if received in the next funding
cycle.
