Etna, CA
Etna wildfire risk explained
USFS's Wildfire Risk to Communities model puts Etna at the 99th national percentile for risk to structures, in USFS's highest wildfire-risk band nationally — a score built from 560 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 Etna at the 99th percentile, close to its 99th-percentile risk score.
Where Etna's buildings actually sit
560 buildings are counted in Etna, and 51.6% 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 Etna compares
Etna scores 99th nationally and 92nd within California — close enough that its state context doesn't change the picture the national number already gives. Among the 31,521 US communities USFS scores, Etna ranks 211 for wildfire risk (1 is highest) and 16,402 by building count (1 is largest). Within California alone, it ranks 119 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
Shopping for coverage in Etna
Etna's 99th-percentile score lands in California, the only two states requiring a wildfire disclosure at sale. California's surplus-lines homeowners market passed 300,000 policies for the first time in 2025, driven by carriers pulling back from wildfire-exposed areas statewide. The disclosure-law guide covers what it requires.
Lowering exposure, not just insuring around it
Because Direct exposure dominates in Etna (51.6%), the highest-leverage fix is defensible space, not roofing or vents alone — covered in the home-hardening guide.
