San Tan Valley wildfire risk explained

High
76thpercentile nationally

San Tan Valley sits at the 76th percentile nationally for wildfire risk to structures — well above the national norm for wildfire risk — per USFS's Wildfire Risk to Communities model, built from its 37,985 counted buildings, not vegetation cover alone. (Source: USFS's Wildfire Risk to Communities methodology.)

Fire likelihood alone (USFS's burn-probability figure) ranks San Tan Valley at the 75th national percentile — 1 points below its risk-to-structures score, a gap driven by how much is actually built there.

What "at risk" means for the buildings here

37,985Total buildings
25.9%Direct exposure
20.5%Indirect exposure
53.6%Minimal exposure

San Tan Valley rates 53.6% Minimal exposure against just 25.9% Direct and 20.5% Indirect — of 37,985 buildings counted, few sit close enough to burnable vegetation for USFS to flag them individually. At 37,985 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.

Where San Tan Valley ranks

San Tan Valley's 76th national percentile looks worse in isolation than its 38th ranking inside Arizona does — this place is on the milder end for its own state, by 39 points. Among the 31,521 US communities USFS scores, San Tan Valley ranks 7,428 for wildfire risk (1 is highest) and 267 by building count (1 is largest). Within Arizona alone, it ranks 276 of 441 places by risk. See the full county-by-county picture for Arizona on its state page.

Shopping for coverage in San Tan Valley

At the 76th percentile nationally, San Tan Valley carries the high rating that has pushed some carriers to limit new business in similarly-scored places elsewhere in the country. Worth comparing quotes rather than assuming last year's renewal terms still apply.

Hardening a home in San Tan Valley

Even with 53.6% of San Tan Valley outside USFS's Direct and Indirect zones, basic hardening — gutter maintenance, ember-resistant vents — is inexpensive relative to the regional burn-probability risk noted above. Details in the home-hardening guide.
