From early August through October, Marin Municipal Water District (MMWD) will replace a failed corrugated metal pipe culvert underneath the Cross Marin Trail at Jewell Creek. The culvert is in disrepair and has a decayed bottom affecting fish passage at this location. MMWD’s Nicasio water transmission line, located above the failing culvert, is also at risk and could be damaged if the culvert fails.
In place of the existing culvert, MMWD will install an open-bottom arch culvert, improving fish passage in Jewell Creek. This project will also restore the Cross Marin Trail and stabilize the Nicasio transmission line in the project vicinity. The portion of the Cross Marin Trail through National Park Service lands, from the northern border of Samuel P. Taylor State Park to Olema Hill will be closed until the completion of the project, when it is once again safe for use by hikers, equestrians and cyclists. Jewell Trail will also be closed for the duration of construction. This project aligns with MMWD’s five-year strategic plan to improve water supply resiliency and maintain facilities and equipment sufficiently.
The Cross Marin Trail meanders along the old North Coast Pacific Railroad grade which once ran between Larkspur to Cazadero. The trail is paved for a portion and runs through Samuel P. Taylor State Park on California State Park lands where users can stroll or bike along majestic redwood trees adjacent to Lagunitas Creek, home to endangered coho salmon and steelhead.
