Mill Valley-Sausalito Multiuse Pathway

CEQA and NEPA Services for a Multiuse Pathway Improvements in Marin County.


  • Meet the requirements of NEPA, Caltrans Local Assistance Guidelines, and CEQA
  • Improve bicycle and pedestrian access and circulation

Marin County’s project consists of repaving an approximately 5,000-foot-long segment of the Mill Valley-Sausalito multiuse pathway, between East Blithedale Avenue and Almonte Boulevard in the City of Mill Valley, Marin County, California.  The existing 10-foot wide asphalt concrete path will be repaved and quarry fines would be placed within the existing shoulders to match grades as needed.  The project also involves replacing and making accessibility improvements to four existing benches located adjacent to the pathway.  The repaving of the path along with the placement of permeable concrete and bench replacements would conform to Americans with Disabilities Act (ADA) standards.

WRA is currently preparing various technical reports pursuant to NEPA and Caltrans Local Assistance, as well as a CEQA Categorical Exemption for this project, overseen by the County of Marin Public Works Department.  In addition, WRA is assisting with preparation of permit applications to the U.S. Army Corps of Engineers, Regional Water Quality Control Board, and Bay Conservation and Development Commission.  WRA provided guidance to project engineers regarding design measures that will ensure the project is designed to avoid impacts to sensitive biological communities and tidal wetlands will be entirely avoided.  WRA is also preparing an environmental constraints analysis and mitigation plan for four bridges to be replaced along the pathway as part of a separate project for Marin County.
