The County of Marin and Federal Highway Administration (FHWA) are proposing improvements to road conditions along a 2.42 mile segment of Muir Woods Road/Frank Valley Road on Marin County land.
This project would restore the structural integrity of 2.42 miles of the road between California Highway 1 (CA 1) and Muir Woods National Monument. The project is a cooperative effort between the Federal Highway Administration, Central Federal Lands Highway Division (FHWA-CFLHD) and Marin County and is being planned in coordination with the National Park Service and California State Parks.
The purpose of the project is to enhance safety for all users accessing state and federal lands, correct road-related drainage problems, reduce water quality impacts to Redwood Creek, and reduce on-going road maintenance requirements.
In addition to road improvements, the project may include replacement of the Muir Woods Road Bridge over Redwood Creek, located just east of the entrance to Muir Woods National Monument. The existing substandard bridge was built in 1946 and needs to be replaced. The aging bridge has exposed bridge footings, deteriorating concrete, and corroded rebar. The bridge railings do not meet current safety standards and scour from Redwood Creek is undermining the structure.
Possible road improvements could include:
> Stabilizing eight road locations adjacent to Redwood Creek where the creek has eroded and undermined the roadway
> Widening the roadway to a consistent 24-foot paved width
> Improving drainage by replacing deteriorating and substandard culverts
> Restoring, rehabilitating, and resurfacing the road to provide a maintainable surface Possible bridge improvements could include:
> Replacing the existing substandard bridge with a new structure that can accommodate two 11- foot lanes, five-foot shoulders, and a six-foot sidewalk
The project may be implemented in two phases. Phase A includes the road project and Phase B involves the bridge project.
A joint environmental assessment and initial study (EA/IS) is being prepared in accordance with the National Environmental Policy Act (NEPA) and the California Environmental Quality Act (CEQA). Scoping is the first step to involve the public in the process. Scoping provides opportunities to identify public concerns early and to focus the analysis on important issues.
