In 2023, California committed $3.7 billion over five years to wildfire prevention — the largest such investment in state history. The money funds fuel breaks, prescribed burns, home hardening, forest thinning, and community evacuation infrastructure.
Three years in, the program is producing measurable results. But the gap between what’s been accomplished and what the state needs remains enormous.
What’s Working
Prescribed Burns Are Scaling Up
California burned 125,000 acres in prescribed fires in 2025 — more than triple the 2020 level. The state’s Prescribed Fire Liability Pilot Program, which shields landowners from liability for burns that escape, has been the single biggest accelerator.
CAL FIRE now has six dedicated prescribed burn crews, up from zero in 2020. The agency has shifted from treating prescribed fire as an occasional tool to building it into its annual operational calendar.
“We’re not where we need to be, but we’re not where we were,” says Battalion Chief Angela Ortiz, who oversees CAL FIRE’s vegetation management program. “Five years ago, suggesting a 5,000-acre prescribed burn in the Sierra would have been career suicide. Now we’re doing them quarterly.”
Fuel Breaks Are Proving Their Value
The state has completed 312 miles of fuel breaks since 2023, concentrated in the Sierra Nevada foothills, the Shasta-Trinity region, and the wildland-urban interface around Southern California communities.
In September 2025, the Mineral Fire in Tehama County ran into a fuel break that had been installed 18 months earlier. The break didn’t stop the fire, but it slowed its advance enough for crews to establish containment lines. Post-fire analysis estimated the break prevented $45 million in structure losses.
Home Hardening Is Getting Traction
California’s Home Hardening Program has retrofitted 28,000 homes in high-risk zones with fire-resistant roofing, ember-resistant vents, and defensible space improvements. The program covers up to $40,000 per home and is means-tested to prioritize lower-income residents.
Insurance companies have taken notice. Three major California insurers have agreed to offer rate reductions for homes that complete hardening requirements, creating a financial incentive that reinforces the state program.
What’s Not Working
Forest Thinning Is Behind Schedule
The state set a goal of treating one million acres of forest per year by 2025. Actual treatment has averaged 400,000 acres — significant, but 60% below target.
The bottleneck is workforce. Forest thinning is labor-intensive, physically demanding work in remote locations. California doesn’t have enough trained forestry workers to hit its targets, and competition from construction and other outdoor industries keeps wages high.
The federal government’s contribution has also lagged. National Forest land makes up 57% of California’s forested area, but the U.S. Forest Service has treated only 150,000 acres per year in California — flat since 2021 despite increased appropriations.
Community Evacuation Infrastructure
The fires that cause the most death and destruction tend to be fast-moving events in the wildland-urban interface, where narrow roads and limited evacuation routes create bottlenecks.
The state has funded evacuation route improvements in 47 communities, but construction is slow. Road widening in fire-prone mountain communities faces the same environmental review and permitting challenges as any other infrastructure project. The cruel irony is that CEQA review — designed to protect the environment — can delay projects that would protect communities from environmental catastrophe.
Climate Is Outpacing Prevention
The fundamental challenge: California’s wildfire prevention efforts are running against a climate that is making fires larger, hotter, and more frequent. Average fire season length has increased by 75 days since 1970. The area burned annually has doubled since the 1990s.
Prevention reduces risk. It doesn’t eliminate it. And as fire behavior becomes more extreme — driven by hotter temperatures, drier vegetation, and stronger winds — the margin of safety that prevention provides gets thinner.
The Hard Math
Wildfire scientists estimate that California needs to treat 20-25 million acres of forest and shrubland to meaningfully reduce fire risk statewide. At current rates, that would take 50 years. Climate change isn’t waiting that long.
The $3.7 billion investment is real and it’s producing results. But it’s also a down payment on a problem that will cost tens of billions more to address — and that can never be fully solved, only managed.
California is learning to live with fire. The question is whether it’s learning fast enough.
