Navarro Watershed Road Sediment Reduction
Mendocino County Resource Conservation District, Mendocino County
Project Abstract
The Navarro Watershed Road Sediment Reduction generally consists of the treatment of unimproved forest and ranch road systems to reduce erosion and save sediment from entering the river system. There will be approximately 18.5 miles of ranch roads upgraded in the Rancheria and Indian Creek sub basins using progressive methods outlined in the Handbook of Forest and Ranch Roads and the California Salmonid Stream Habitat Manual, Chapter 10.
Project Goals
- The total project goal is to apply erosion prevention treatments on 37 miles of unimproved ranch roads to prevent 48,535 cu. yds of sediment from entering streams. This project addresses 18.5 miles of road, 23,972 cubic yds of sediment from entering streams, 164 stream crossings, and 136 road segments. The balance is addressed in the application for 319(h) funding.
- Replace, install, reinstall and/or minimize diversion potential and erosion at 202 stream crossings with culverts sized for 100-year storm events
- Outslope roads and remove berms, fill inboard ditches, and install rolling dips along 206 road segments
- Clean culverts, and install trash racks to prevents culverts from plugging (where applicable)
