Needs & benefits

This work is part of WSDOT's Fish Passage Barrier Removal Program. WSDOT working with the Department of Fish and Wildlife identifies barriers to fish passage caused by inadequate culverts under state highways. Chico Creek has undersized culverts that serve as barriers to fish.

These barriers currently are under both directions of SR 3 and under both highway on- and off-ramps.

How will this work be done?
This project will use the Design-Build method of project delivery. Working under a single contract, the Design-Builder will both engineer and build the project.

WSDOT will work closely with the Design-Builder to help keep travelers moving during this work to remove the barriers to fish and build a replicated natural streambed for Chico Creek under SR 3.

The End Result
Removing the barriers to fish will make the stream more maneuverable for migrating fish by extending usable habitat. The enhancements for Chico Creek at this location will improve access to 21 miles of habitat and build up similar efforts by Kitsap County to remove barriers that impede fish migration.

In addition, the work will help preserve the integrity of the highway and reduce maintenance costs by reducing or eliminating the possibility of the culvert blockages.
