Vienna, VA
Vienna, VA's wildfire risk, in USFS's own numbers
Vienna's 5,488 buildings earn a 16th-percentile wildfire-risk score nationally under USFS's model — among the lower wildfire-risk places nationally. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Vienna at the 16th national percentile — 0 points above its risk-to-structures score, a gap driven by how much is actually built there.
Where Vienna's buildings actually sit
45.5% of Vienna's 5,488 buildings sit in USFS's Direct exposure zone, roughly 2,498 structures close enough to burnable vegetation for flame contact, not just embers — 24.1% fall in the Indirect, ember-only zone and 30.4% are Minimal. At 5,488 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.
Where Vienna ranks
Vienna's risk sits at a similar level relative to Virginia (7th percentile statewide) as it does nationally (16th) — this place isn't unusual for its own state either way. Among the 31,521 US communities USFS scores, Vienna ranks 26,457 for wildfire risk (1 is highest) and 3,144 by building count (1 is largest). Within Virginia alone, it ranks 637 of 681 places by risk. See the full county-by-county picture for Virginia on its state page.
Vienna and the insurance market
At the 16th national percentile, Vienna rates low for wildfire risk — well short of the threshold where insurers have been withdrawing coverage, though comparing a quote costs nothing either way.
What would actually reduce this score
Because Direct exposure dominates in Vienna (45.5%), the highest-leverage fix is defensible space, not roofing or vents alone — covered in the home-hardening guide.
