Hogback Ridge is getting a hard reset. Crews are cutting, burning and grinding away thick brush in a focused fuel reduction push meant to slow future wildfires before they spill into Napa Valley. The work links hand crews, pile burns and mechanical thinning into a continuous ridgeline break that firefighters can use as a defensible line when the next big fire comes calling.
A newly released video dishes up a steep-slope view of the project, showing crews and machinery carving a break through dense vegetation high above the valley. According to the Napa Valley Register, the footage was shot by county and nonprofit partners who are coordinating the operation.
What the project covers
County records show the Hogback Ridge CalVTP project is set to treat roughly 431 acres along the Napa-Sonoma ridgeline, with approval granted on Sept. 3, 2025. The State Clearinghouse filing in the California Environmental Quality Act database describes it as a strategic fuel break under the California Vegetation Treatment Program and notes mitigation and monitoring measures tied to that approval, according to CEQAnet. Napa County Fire Administration is listed as the lead agency overseeing the effort.
Who is leading and funding the work
The project is being coordinated by the Napa Communities Firewise Foundation alongside county fire teams, local fire safe councils and vineyard landowners. As detailed by the Napa Communities Firewise Foundation, the work was seeded with a U.S. Forest Service grant and matching funds totaling nearly $3 million. “This project is about correcting course,” said Mike Wilson, Napa Firewise’s director of land resilience.
How crews are working the ridge
To knock back the fuel load, crews are using a mix of hand work, mechanical thinning and pile burning to break up continuous vegetation and open safer access for firefighters. The operation has also brought in a remote-controlled mulching machine, locally known as “BurnBot,” to tackle steep, hazardous slopes, as reported by Patch. Officials say this blend of targeted treatments and new tools is intended to lower fire intensity and make suppression work less dangerous.
Why it matters for Napa Valley
Last summer’s Pickett Fire was a blunt reminder of the stakes: the blaze burned more than 6,800 acres in Napa County and prompted evacuations, according to CAL FIRE. Reporting from KQED notes that existing fuel breaks and access roads helped crews hold lines during that incident, reinforcing why treated ridgelines like Hogback are treated as critical infrastructure. Project backers say the Hogback work is designed to offer those same tactical advantages before the next major fire.
