Description:

Caltrans proposes to rehabilitate and restore 45 existing drainage systems between PM 0.0 to 43.0 along State Route (SR) 254, also known as Avenue of the Giants (i.e., Humboldt Redwoods State Park), in Humboldt County, California. Repairing the damaged culverts will reduce sediment input to the Eel River and South Fork of the Eel River. The project also includes restoration activities to improve habitat conditions for fish passage at Chadd Creek, Mowry Creek, and an unnamed intermittent tributary of the South Fork Eel River at PM 8.13. The proposed work at 42 other culverts in the action area are not accessible to anadromous fish species.
