DESCRIPTION
This restoration project improved instream and floodplain habitat along 2 miles of the Skykomish River near Sultan, WA. Overall, the Lower Skykomish River Restoration is a 2.8 mile phased, multi-site, multi-benefit project. With this project, a combination of strategies were applied that work with natural channel processes to promote habitat and water quality improvement, and to help safeguard the productivity of adjoining floodplain areas. Floodplain flood fencing was installed along 6000 lineal feet of river bank adjacent to active agriculture fields. The flood fencing was inter-planted with conifer trees. Two in-channel flood fence arrays and six small modular log jam structures were completed in Groeneveld Slough. Twenty-five (25) large habitat boulder-ballasted logs with rootwads were placed on the bed of an off-channel slough (Bahnmiller site). Six flood fence arrays were installed on the meander bar upstream on the Labish property. A jam structure was placed, consisting of 11 large logs with rootwads, downstream of the instream bar flood fencing. Thirty-six (36) habitat boulder-ballasted rootwad logs were installed along 370 foot of pool habitat overlapped in an open structure formation. Adjacent to the enhanced pool, the simplified bank edge (370 feet) was rehabilitated by reducing the vertical eroding slope to 3:1, adding edge complexity wood structures, bio-engineered fabric and plantings. This project resulted from a reach scale geomorphic analysis (attachment #99027) of the lower Skykomish River below Sultan (RM 0 to RM 13.5) Snohomish County conducted to identify and design specific restoration projects that will be consistent with natural processes.This project included high priority actions identified in the adopted 2005 Snohomish Basin Chinook Recovery Plan, 2010 Lower Skykomish River Restoration Assessment, and the County-facilitated Sustainable Lands Strategy Skykomish River Reach Scale Plan. This project was also identified as a Tier 1, primary focus reach project in the Puget Sound Partnership 3-Year Work Plan. Moving this project from plan to implementation depended on multiple partnerships and serves as a model for the reach scale, multiple benefit approach.
