Soda Creek Fish Passage and Winter Habitat Refugia Design Project

The purpose of the Project is to produce final (100%) engineered designs to restore fish access to 2.6 miles of habitat by replacing a culvert that is a partial barrier to Coho Salmon and Steelhead trout near the mouth of Soda Creek. The specific objective of this Project is to develop 100% final designs to remediate the existing partial barrier to fish passage near the mouth of Soda Creek and habitat improvements 500 feet immediately upstream (Phase 1 Restoration). The design effort will also include site characterizations and development of a conceptual restoration plan for an additional 4,200 feet of habitat in Lower Soda Creek (Phase 2 Restoration).

The project goal is to produce final engineered designs for the Mendocino Redwood Company (MRC) Soda Creek stream crossing that, when implemented, will restore fish access to approximately 2.6 miles of upstream habitat. The project will also develop final designs for instream enhancement activities along approximately 500 feet of existing winter refugia habitat (Phase 1, Crossing Replacement Reach), will develop a conceptual instream enhancement plan for an additional 4,200 feet of habitat in Lower Soda Creek (Phase 2, Lower Soda Creek Planning Reach), and will complete CEQA-related surveys of the project area to prepare for future construction activities.
