Description

A restoration plan for 2,500 feet of North Creek adjoining the Mill Creek City Hall was designed by The Watershed Company to improve fish and wildlife habitat and stabilize bank erosion that threatened a paved City trail. We provided conceptual plans for 13 specific project locations. On the basis of these concept designs, Department of Fish and Wildlife permitting was obtained, as well as grant funding for implementation at 7 of the 13 sites. Final engineering design and specifications, Biological Evaluation preparation, and permitting applications were completed.

The project included a number of different bioengineered bank stabilization applications incorporating closely placed logs with attached root wads to provide bank definition, known as root wad revetments. Our designs of interlocking upright and horizontal logs add stability and complexity. These structures have formed pools with abundant cover for fish use at the outside of channel bends. Non-native vegetation removal and native vegetation planting are providing shade, bank stability, and wildlife habitat. A multi-year performance-monitoring program is under way.
