Napa Wildfire Study Eyes Funding Prevention, Improving Insurance Availability

A new report looks into how to put more resources into prevention before a wildfire strikes, maintain resilience and direct new investment where it can deliver the greatest value using Napa, California as a case study.

The Napa County wildfire resilience study found substantial prevention work already underway in the area, but it identified gaps in long-term funding and maintenance that could limit its effectiveness.

The Napa Wildfire Resilience System Phase 1 report, developed by the Darwin Fund with support from CSAA Insurance Group, examines how existing wildfire prevention programs could be coordinated and financed to produce sustained reductions in wildfire risk. The study also explores whether those investments could improve insurance availability and reduce losses.

The report found that Napa has substantial wildfire prevention programs and investment already in place, but long-term maintenance funding remains fragmented. Fuel breaks, evacuation routes, utility corridors and property mitigation measures can lose effectiveness without continued maintenance.

The analysis identified 552 parcel records in Napa’s Enhanced Resilience Site pipeline, including 408 parcels with work in progress and 144 classified as integrated, meaning they had completed the certification process. State treatment records also identified 54 projects, 99 treatments and roughly 6,200 acres of recorded treatment activity. Napa Firewise reports that 10 to 15 new landowners enter the resilience process monthly, with certification generally taking 30 to 60 days. Certificates remain valid for one year.

The study proposes testing whether mitigation measures across neighborhoods and communities can produce measurable benefits for insurers, including reduced expected losses, lower catastrophe exposure, improved underwriting capacity and greater insurance availability.

However, the initial study did not establish that existing mitigation efforts have reduced insurance premiums, improved coverage or produced measurable insurer cost savings. The report also found that no dedicated repayment source or investment-ready financing structure has been established for a Napa-scale resilience program.

A second phase of the project would examine the effectiveness and maintenance costs of selected prevention measures, evaluate potential insurance and utility benefits, and determine whether public funding, private contributions or a proposed California Optimization Bond financing structure could support continued investment.

The first phase drew on more than 200 public sources, local wildfire treatment and parcel records, planning documents, and information provided by Napa Firewise and PG&E.
