Grizzly Flats, CA
Grizzly Flats, CA's wildfire risk, in USFS's own numbers
USFS's Wildfire Risk to Communities model puts Grizzly Flats at the 99th national percentile for risk to structures, in USFS's highest wildfire-risk band nationally — a score built from 426 actual buildings. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Grizzly Flats at the 100th national percentile — 0 points above its risk-to-structures score, a gap driven by how much is actually built there.
What "at risk" means for the buildings here
426 buildings are counted in Grizzly Flats, and 99.1% of them sit in USFS's Direct exposure zone — flame contact, not just ember cast, is the live possibility for most of them, against 0% rated Minimal.
How Grizzly Flats compares
Grizzly Flats's risk sits at a similar level relative to California (93rd percentile statewide) as it does nationally (99th) — this place isn't unusual for its own state either way.

Within California alone, it ranks 107 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
Grizzly Flats and the insurance market
Because Grizzly Flats is in California, a wildfire-hazard disclosure is legally required before a sale closes here — unusual nationally, since only these two states mandate it. The state's FAIR Plan alone carried 668,609 policies by the end of 2025. Full detail in the disclosure-law guide.
What would actually reduce this score
Because Direct exposure dominates in Grizzly Flats (99.1%), the highest-leverage fix is defensible space, not roofing or vents alone — covered in the home-hardening guide.
