Vienna, MO
Vienna, MO's wildfire risk, in USFS's own numbers
Out of every US place USFS scores, Vienna lands at the 66th percentile for wildfire risk to structures — well above the national norm for wildfire risk — a figure built from its 422 buildings, not the land around them. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Vienna at the 69th national percentile — 2 points above its risk-to-structures score, a gap driven by how much is actually built there.
Vienna's building exposure, zone by zone
Most of Vienna's buildings (54.5%) sit in the Indirect zone, where wind-blown embers rather than flame front are the mechanism USFS is scoring — ember-resistant vents and non-combustible roofing are the interventions this pattern favors, more than defensible space alone.
Vienna against the rest of the country
Vienna's risk sits at a similar level relative to Missouri (72nd percentile statewide) as it does nationally (66th) — this place isn't unusual for its own state either way. Among the 31,521 US communities USFS scores, Vienna ranks 10,683 for wildfire risk (1 is highest) and 18,790 by building count (1 is largest). Within Missouri alone, it ranks 296 of 1,062 places by risk. See the full county-by-county picture for Missouri on its state page.
Shopping for coverage in Vienna
Vienna's 66th-percentile, high rating is the kind of score behind a broader national pattern: insurers pulling back from the highest wildfire-risk markets, non-renewing or declining new policies outright, most visibly in California. Shopping around, not assuming automatic renewal, tends to matter here.
What would actually reduce this score
Because 54.5% of Vienna's buildings sit in the Indirect zone, sealing the ember pathway (vents, roofing, gutters) is the intervention this page's data actually supports — see the home-hardening guide.
Where Vienna's figures come from
Vienna's 66th-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 Vienna's dominant indirect exposure actually means, with real examples from across the dataset.
