Document Description
Caltrans proposes to replace the two existing 60-foot long corrugated metal pipe (CMP) culverts on South Fork Ryan Creek along SR 101 (PM 52.25) with double 120-foot long jacked steel pipe culverts, and the existing 60-foot long CMP culvert on North Fork Ryan Creek along SR 101 (PM 52.36) with a 12-foot x 10-foot reinforced concrete culvert. Rock weirs, rock sills and native materials will be placed in the creek at both locations to provide an engineered streambed that provides fish passage for all stages of salmonid and is acceptable to the CDFW and the National Marine Fisheries Service (NMFS). The increased culvert size is designed to remove barriers to fish passage as a requirement of the Willits Bypass Incidental Take Permit issued by the CDFW.
