Coal Creek Culvert Replacement

Pacific Coast Salmon Coalition

Project Description Coal Creek is a tributary to the Dickey River. The Dickey River and

its’ tributaries provide abundant low-gradient habitat for spawning and rearing Coho, Steelhead and Cutthroat. The Dickey drainage is known as one of the top Coho smolt producers (measured by square kilometer of drainage) in Washington State. The Dickey confluences with the Quillayute River in the Quillayute Esturary.

The culvert on Coal Creek we will be addressing is under the 5000 line, a well used logging road. The current structure is a 96” CMP that is perched and undersized. The average stream width upstream is 14’ with a 20” outfall drop that plunges directly onto large rip rap, placed to protect the road, creating an obstacle to salmonid migrating upstream to access the habitat above the blocking culvert. Because the pipe is undersized at the inlet there is a whirlpool effect that is resulting in bank destabilization. There is approximately 6’ of road fill covering the CMP.

RMAP Project Requirements Project is not solely mitigation. Project is not Mitigation Project is an expedited action ahead of the Department of

Natural Resources approved RMAP schedule. Project is currently scheduled for 2016

Expedited actions do not include RMAP projects that might be delayed beyond their originally scheduled completion date. It will be 4 years earlier

Project must provide a clear benefit to salmon recovery. It opens almost 3 miles of habitat

There will be harm to salmon recovery if the project is delayed (i.e., not completed earlier than the scheduled RMAP completion date). 3 miles of habitat, inaccessible

Large landowners must provide 35 percent match for fish passage projects and 50 percent for sediment reduction projects. Meets 35% criteria and is a fish passage blockage

Priority Listed in the North Pacific Coast Lead

Entity Strategy, Appendix B: 2011 Project List as a priority project.
