Green Creek Restoration Design-Build

Green Creek is a large tributary of the Pysht River that supports populations of coho, chinook, and chum salmon as well as steelhead, cutthroat trout, and Pacific Lamprey. Habitat conditions in Green Creek have been simplified, primarily due to the chronic loss of in-channel wood as a result of historic forest management. In this project, the Tribe will hire a qualified engineering firm to conduct a geomorphic, hydrologic, and hydraulic analysis of Green Creek from its confluence with the Pysht River to River Mile 1.5. That analysis will inform a Basis of Design Report which will be used to produce engineering designs for the restoration of spawning and rearing habitat used by Pacific salmon. A cost estimate will also be generated for implementing the restoration. The design and cost estimate will be used to help procure future grant funds to construct the project in its entirety. A portion of the FY 23 funds will be used to purchase materials for that restoration, specifically 100 rock collars. We anticipate the restoration project to utilize a heavy lift helicopter that will place wood in complex arrangements. Rock collars will be used to anchor those wood pieces.

The objectives of this project are to complete a final restoration design for the lower 1.5 miles of Green Creek, a Pysht River tributary. That design, when implemented will result in improved spawning and rearing conditions throughout the reach. A portion of this project will be retained to begin purchasing and assembling materials for a future restoration project, specifically 100 rock collars. The future restoration project will require additional funding that the Tribe will seek once the design is completed.
