Williams, AZ
Williams, AZ's wildfire risk, in USFS's own numbers
USFS's Wildfire Risk to Communities model puts Williams at the 98th national percentile for risk to structures, in USFS's highest wildfire-risk band nationally — a score built from 1,923 actual buildings. (Source: USFS's Wildfire Risk to Communities methodology.)
Separately from the risk score above, Williams's burn probability — fire likelihood with no building count factored in — sits at the 98th percentile nationally.
Where Williams's buildings actually sit
1,923 buildings are counted in Williams, and 57.9% of them are Indirect exposure — ember-driven risk rather than the 42.1% in Direct exposure or the 0% rated Minimal.
Williams against the rest of the country
Williams scores 98th nationally and 91st within Arizona — close enough that its state context doesn't change the picture the national number already gives. Among the 31,521 US communities USFS scores, Williams ranks 529 for wildfire risk (1 is highest) and 7,698 by building count (1 is largest). Within Arizona alone, it ranks 46 of 441 places by risk. See the full county-by-county picture for Arizona on its state page.
Williams and the insurance market
Williams's 98th-percentile, very high rating is the kind of score behind a broader national pattern: insurers pulling back from the highest wildfire-risk markets, non-renewing or declining new policies outright, most visibly in California. Shopping around, not assuming automatic renewal, tends to matter here.
What would actually reduce this score
Because 57.9% of Williams's buildings sit in the Indirect zone, sealing the ember pathway (vents, roofing, gutters) is the intervention this page's data actually supports — see the home-hardening guide.
More on how this number was built
Williams's 98th-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. For more on what indirect exposure implies beyond Williams, see the exposure-zones guide.
