Petersburg, TN
Petersburg wildfire risk explained
Petersburg sits at the 32nd percentile nationally for wildfire risk to structures — close to the middle of USFS's national wildfire-risk range — per USFS's Wildfire Risk to Communities model, built from its 396 counted buildings, not vegetation cover alone. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Petersburg at the 35th national percentile — 3 points above its risk-to-structures score, a gap driven by how much is actually built there.
Where Petersburg's buildings actually sit
Of Petersburg's 396 counted buildings, 69.2% carry Direct exposure and only 0% carry Minimal — a lopsided split that puts defensible-space clearing ahead of vents or roofing as the intervention worth doing first.
Where Petersburg ranks
There's little gap between Petersburg's 32nd national percentile and its 21st percentile inside Tennessee, which means the state comparison mostly confirms what the national score already shows. Among the 31,521 US communities USFS scores, Petersburg ranks 21,507 for wildfire risk (1 is highest) and 19,310 by building count (1 is largest). Within Tennessee alone, it ranks 398 of 502 places by risk. See the full county-by-county picture for Tennessee on its state page.
What this risk score means for insurance
At the 32nd national percentile, Petersburg rates moderate for wildfire risk — well short of the threshold where insurers have been withdrawing coverage, though comparing a quote costs nothing either way.
Lowering exposure, not just insuring around it
With 69.2% of Petersburg in Direct exposure, defensible-space clearing and ember-resistant construction (vents, Class-A roofing) address the exposure this page's own numbers describe, not a generic checklist. See the home-hardening guide.
More on how this number was built
Petersburg's 32nd-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. For more on what direct exposure implies beyond Petersburg, see the exposure-zones guide.
