Colusa, CA
Colusa, CA's wildfire risk, in USFS's own numbers
USFS's Wildfire Risk to Communities model puts Colusa at the 68th national percentile for risk to structures, well above the national norm for wildfire risk — a score built from 2,699 actual buildings. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Colusa at the 65th percentile, close to its 68th-percentile risk score.
Where Colusa's buildings actually sit
USFS classifies 89.3% of Colusa's buildings as Minimal exposure, the largest of the three zones here by a wide margin over 9.6% Direct and 1.2% Indirect — a landscape-level risk rather than a building-by-building one.
Colusa against the rest of the country
Colusa's 68th national percentile looks worse in isolation than its 25th ranking inside California does — this place is on the milder end for its own state, by 43 points. Among the 31,521 US communities USFS scores, Colusa ranks 10,044 for wildfire risk (1 is highest) and 5,931 by building count (1 is largest). Within California alone, it ranks 1,170 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
What this risk score means for insurance
Because Colusa 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
With 89.3% of buildings rated Minimal exposure, Colusa gets less benefit from structure hardening than a Direct- or Indirect-dominant place would — the home-hardening guide explains why the zone matters.
