Project Description

The California Department of Transportation (Caltrans), in cooperation with Calaveras County, proposes to mitigate for Project impacts resulting from the State Route 4 Wagon Trail Realignment Project (SCH Number 2015092066) by placing a conservation easement and completing habitat enhancements on a 41-acre portion of Parcel Number 040-002-027-000 about 13.5 miles north of the State Route 4 Realignment Project. The parcel is privately owned.

Project Benefits


The purpose of the project is to enhance, restore, and protect California red-legged frog habitat by constructing a pond, establishing riparian and oak woodland habitat, and conserving about 2,700 linear feet of Youngs Creek tributary within the easement area.


The proposed project is needed to mitigate for impacts to oak woodland habitat, riparian habitat, California red-legged frog dispersal habitat, and jurisdictional waters as a result of Phase 1 of the State Route 4 Realignment Project.
