Greater Mill Valley Fuel Break Project

The Greater Mill Valley Fuel Break Project, managed by the Marin Wildfire Prevention Authority, aims to establish and maintain a continuous fuel reduction and wildfire resilience zone to mitigate wildfire intensity and rate of spread. The project involves vegetation management activities to create an approximately 23-mile-long shaded fuel break across a 673-acre area. This strategic effort is designed to protect the City of Mill Valley, residential communities in southern unincorporated Marin County including Muir Woods Park, and specific areas within the City of Larkspur and Town of Corte Madera, while providing critical access points for emergency personnel and firefighters. The project was approved on August 21, 2025, and is classified as a forecast under NAICS code 541620. A Notice of Determination has certified that the project will not have a significant effect on the environment, following the completion of an Environmental Impact Report and Project Specific Analysis in compliance with CEQA. Mitigation measures have been integrated as conditions of approval, supported by a formal monitoring and reporting plan. Primary administrative contact for the project is Anne Crealock, Planning and Program Manager, based in San Rafael, California.
