Document Description
Fire Safe Sonoma proposes to conduct grant-funded hazard fuels roadside hazard reduction work, which includes fuel reduction along both sides of Saint Helena Road, approximately 30’ from the edge of pavement, for 7 miles from Calistoga Road to the Napa/Sonoma County Line. This project will include trimming of surface fuels and ladder fuels; removal of dead trees, brush and grass; thinning and limbing remaining trees; removing vegetation <4” DBH; removing selected large hazard trees; and removing branches overhanging the roadway while retaining enough canopy to provide shade. Invasive species to be removed include yellow star thistle, broom (french and/or scotch), and Himalayan Blackberry. Heavy equipment will remain along the road prism, and no ground disturbing activities will occur. Cut materials from native species under 10” in diameter will be chipped and spread on site to act as a mulch for the project area. Cut native materials over 10” in diameter will be scattered or hauled for disposal. All invasive species will be hauled for disposal.
