Decatur wildfire risk explained

High
76thpercentile nationally

USFS scores Decatur at the 76th national percentile for wildfire risk to structures (well above the national norm for wildfire risk), a figure built from 167 real buildings rather than raw vegetation cover. (Source: USFS's Wildfire Risk to Communities methodology.)

USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Decatur at the 77th percentile, close to its 76th-percentile risk score.

What this risk score means for insurance

Decatur's high rating (76th 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.

Hardening a home in Decatur

With ember exposure the dominant pattern in Decatur (54.5% Indirect), vent screens and roofing material tend to matter more than lot clearing alone. The home-hardening guide covers both.
