South Vienna, OH
South Vienna, OH's wildfire risk, in USFS's own numbers
USFS scores South Vienna at the 5th national percentile for wildfire risk to structures (among the lower wildfire-risk places nationally), a figure built from 288 real buildings rather than raw vegetation cover. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks South Vienna at the 5th national percentile — 0 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
USFS classifies 80.9% of South Vienna's buildings as Minimal exposure, the largest of the three zones here by a wide margin over 19.1% Direct and 0% Indirect — a landscape-level risk rather than a building-by-building one.
South Vienna against the rest of the country
Compare South Vienna's two percentiles: 23rd within Ohio, only 5th nationally — a gap of 19 points that marks it as unusually exposed for its own state. Among the 31,521 US communities USFS scores, South Vienna ranks 30,054 for wildfire risk (1 is highest) and 21,971 by building count (1 is largest). Within Ohio alone, it ranks 968 of 1,264 places by risk. See the full county-by-county picture for Ohio on its state page.
South Vienna and the insurance market
South Vienna's low wildfire rating (5th percentile) isn't the kind of score driving the carrier pullback making news in the highest-risk Western markets — but a standard homeowners quote is still worth comparing on its own terms.
Hardening a home in South Vienna
Even with 80.9% of South Vienna outside USFS's Direct and Indirect zones, basic hardening — gutter maintenance, ember-resistant vents — is inexpensive relative to the regional burn-probability risk noted above. Details in the home-hardening guide.
