Project Status - Complete
Project vicinity near Poulsbo.

Overview
This project provides improved access to upstream freshwater habitat for migratory fish. Migratory fish use freshwater habitat for food and as spawning grounds.

The previous double culvert at the unnamed tributary (Lemolo Creek) was replaced with 10-foot diameter culvert, and a culvert at Bjorgen Creek was replaced with a 12-foot diameter culvert.

The Bjorgen Creek fish culvert replacement cost approximately _________, which is not reflected in the below project totals.

The bottom of the new culverts are five feet below the natural level of the streambed. Crews have placed streambed gravel and rock inside the culverts to simulate natural streambeds.

How You Benefit
Leaf Glyph Protects Environment
The new culverts improve fish passage under the roadway by simulating natural streambeds. In addition, each streambed has been regraded upstream and downstream from the culverts. Regrading the streambeds and placing new rock provides and protects spawning grounds when water volumes increase during storms.

Partnerships & Cooperation
WSDOT was able to address residents' concerns about a previously planned, temporary closure of SR 305 and detour route. After discussions with city officials, WSDOT engineers were able to rework plans and dramatically reduce traffic impacts.
