Lorton, VA
Lorton, VA's wildfire risk, in USFS's own numbers
Lorton's 3,020 buildings earn a 35th-percentile wildfire-risk score nationally under USFS's model — close to the middle of USFS's national wildfire-risk range. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Lorton at the 34th percentile, close to its 35th-percentile risk score.
What "at risk" means for the buildings here
Most of Lorton's buildings (59.3%) 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.
How Lorton compares
Lorton scores 35th nationally and 25th within Virginia — close enough that its state context doesn't change the picture the national number already gives. Among the 31,521 US communities USFS scores, Lorton ranks 20,439 for wildfire risk (1 is highest) and 5,399 by building count (1 is largest). Within Virginia alone, it ranks 511 of 681 places by risk. See the full county-by-county picture for Virginia on its state page.
Lorton and the insurance market
Lorton's moderate wildfire rating (35th 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 Lorton
Lorton's 59.3% 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.
