Project Name

Buck Gulch Falls Trail Improvements

Improving visitor safety and reducing erosion in Buck Gulch

The proposed concepts in Ignacio Valley Preserve would improve visitor experience and accessibility, remove foot traffic from the Arroyo San Jose stream, and enhance sustainability of the trail consistent with the Open Space District’s Road and Trail Management Plan. The installation of pedestrian bridges would allow hikers to safely use the trail during wet weather, reduce erosion and sediment, and improve seasonal habitat for aquatic wildlife.
