Geyserville, CA
How exposed is Geyserville to wildfire?
USFS's Wildfire Risk to Communities model puts Geyserville at the 82nd national percentile for risk to structures, in USFS's highest wildfire-risk band nationally — a score built from 703 actual buildings. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Geyserville at the 82nd national percentile — 0 points above its risk-to-structures score, a gap driven by how much is actually built there.
Where Geyserville's buildings actually sit
Indirect exposure is dominant in Geyserville (81.1% of 703 buildings): far enough from burnable vegetation to avoid flame contact, close enough for wind-blown embers. Only 18.9% sit in the Direct zone.
Where Geyserville ranks
Geyserville ranks lower within California (43rd percentile statewide) than its 82nd national percentile suggests alone — a calmer spot in a state where wildfire risk generally runs high. Among the 31,521 US communities USFS scores, Geyserville ranks 5,696 for wildfire risk (1 is highest) and 14,617 by building count (1 is largest). Within California alone, it ranks 891 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
Geyserville and the insurance market
Geyserville's 82nd-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.

Geyserville's 81.1% Indirect-exposure share points at embers, not flame contact, as the main pathway — ember-resistant vents and non-combustible roofing rank ahead of defensible space here. Detail in the home-hardening guide.
Where Geyserville's figures come from
Geyserville's 82nd-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. The exposure-zones guide covers what Geyserville's dominant indirect exposure actually means, with real examples from across the dataset.
