Greater Ross Valley Shaded Fuel Break Project

Use slider bar above to explore an example of a shaded fuelbreak, before and after treatment

This project is a collaboration of the Greater Ross Valley fire agencies (Marin County Fire Department, Ross Valley Fire Department, Kentfield Fire Protection District, and Central Marin Fire Department) and includes mapping, modeling, project design, collaboration with potential partner agencies, public outreach and community meetings, field surveys, and environmental compliance for a shaded fuel break that would be located directly adjacent to communities in the Greater Ross Valley. This project would reduce fire risk to several WUI communities and thousands of residents while improving forest and ecosystem health by reducing non-native plant cover. Future years would include phased implementation of recommended vegetation management activities along the shaded fuel break.


On August 17, 2022, MWPA, Ecologically Sound Practices Partnership, Marin County Parks, and Central Marin Fire hosted a field trip to see part of the first phase of the Greater Ross Valley Shaded Fuel Break. Nearly 50 people attended. Check back here in the near future for photos from this event.

Date: Wednesday, August 17

Time: 9:30-noon

Location: Terra Linda / Sleepy Hollow Preserve

To view the project area spatially, click on this link: Overview KMZ to open up a KMZ file. This file is viewable using Google Earth and allows the user to navigate and zoom into different parts of the project area. Note that the Overview KMZ shows the shaded fuel break as 300 feet wide, although typically fuel and forest health restoration treatments would occur within a 200-foot-wide zone.
