Williston, TN
Williston wildfire risk explained
Williston sits at the 74th percentile nationally for wildfire risk to structures — well above the national norm for wildfire risk — per USFS's Wildfire Risk to Communities model, built from its 256 counted buildings, not vegetation cover alone. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Williston at the 78th national percentile — 3 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
Of Williston's 256 counted buildings, 99.6% carry Direct exposure and only 0% carry Minimal — a lopsided split that puts defensible-space clearing ahead of vents or roofing as the intervention worth doing first.
How Williston compares
Williston's risk sits at a similar level relative to Tennessee (76th percentile statewide) as it does nationally (74th) — this place isn't unusual for its own state either way. Among the 31,521 US communities USFS scores, Williston ranks 8,074 for wildfire risk (1 is highest) and 22,960 by building count (1 is largest). Within Tennessee alone, it ranks 122 of 502 places by risk. See the full county-by-county picture for Tennessee on its state page.
Williston and the insurance market
Williston's high rating (74th percentile) puts it among the places where the national carrier-pullback trend is most relevant — not a guarantee of a coverage problem, but a reason to shop rather than assume.
Lowering exposure, not just insuring around it
With 99.6% of Williston in Direct exposure, defensible-space clearing and ember-resistant construction (vents, Class-A roofing) address the exposure this page's own numbers describe, not a generic checklist. See the home-hardening guide.
More on how this number was built
Williston's 74th-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. For more on what direct exposure implies beyond Williston, see the exposure-zones guide.
