Joanna, SC
Joanna, SC's wildfire risk, in USFS's own numbers
USFS's Wildfire Risk to Communities model puts Joanna at the 66th national percentile for risk to structures, well above the national norm for wildfire risk — a score built from 1,023 actual buildings. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Joanna at the 68th national percentile — 3 points above its risk-to-structures score, a gap driven by how much is actually built there.
Where Joanna's buildings actually sit
Of Joanna's 1,023 counted buildings, 51.2% 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 Joanna ranks
Joanna's 66th national percentile looks worse in isolation than its 37th ranking inside South Carolina does — this place is on the milder end for its own state, by 28 points. Among the 31,521 US communities USFS scores, Joanna ranks 10,881 for wildfire risk (1 is highest) and 11,780 by building count (1 is largest). Within South Carolina alone, it ranks 298 of 474 places by risk. See the full county-by-county picture for South Carolina on its state page.
Shopping for coverage in Joanna
Joanna's high rating (66th percentile) puts it among the places where the national carrier-pullback trend is most relevant — not a guarantee of a coverage problem, but a reason to shop rather than assume.
Lowering exposure, not just insuring around it
With 51.2% of Joanna 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
Joanna's 66th-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 Joanna, see the exposure-zones guide.
