Funding for this project will be used to restore habitat for steelhead in upper Sonoma Creek, with a focus on winter high flow refugia and reducing bed scour, identified as Limiting Factors for Steelhead recovery in this watershed. The Project will serve as a high visibility demonstration project to improve salmonid habitat and mobilize support for additional restoration amongst the many private landowners along Sonoma Creek. The Project will involve removing fill that has confined the channel, and creating a low floodplain with large wood elements, to provide a winter high flow refugia and to induce gravel deposition and local scour pool formation in the channel. This Project will advance the design through 90% and 100% Designs, obtain permits, and provide funding needed to complete project construction.

The primary goal of the Upper Sonoma Creek Restoration Vision is to improve spawning conditions for adult steelhead along with winter and summer rearing habitat for juvenile steelhead. Specific objectives of this Project are to:
1. Restore and increase the availability of floodplain habitat by 0.46 acre to improve habitat conditions for juvenile steelhead.
2. Improve water quality and reduce flow velocities.
3. Reduce erosion and in channel sedimentation.
4. Restore, increase, and enhance riparian habitat and streambank conditions.
5. Control invasive nonnative riparian vegetation to reach a target of 80% native vegetation.
6. Educate the public and build support for a wider restoration vision.
