Warrenville, SC's wildfire risk, in USFS's own numbers
Warrenville's 672 buildings earn a 68th-percentile wildfire-risk score nationally under USFS's model — well above the national norm for wildfire risk. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Warrenville at the 66th percentile, close to its 68th-percentile risk score.
What "at risk" means for the buildings here
Indirect exposure is dominant in Warrenville (51.9% of 672 buildings): far enough from burnable vegetation to avoid flame contact, close enough for wind-blown embers. Only 48.1% sit in the Direct zone.
Where Warrenville ranks
Warrenville ranks lower within South Carolina (48th percentile statewide) than its 68th national percentile suggests alone — a calmer spot in a state where wildfire risk generally runs high. Among the 31,521 US communities USFS scores, Warrenville ranks 10,190 for wildfire risk (1 is highest) and 14,953 by building count (1 is largest). Within South Carolina alone, it ranks 252 of 474 places by risk. See the full county-by-county picture for South Carolina on its state page.
What this risk score means for insurance
Warrenville's high rating (68th 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.
Hardening a home in Warrenville
Warrenville's 51.9% 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.
