San Luis, AZ
San Luis wildfire risk explained
San Luis sits at the 63rd 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 7,022 counted buildings, not vegetation cover alone. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts San Luis at the 64th percentile, close to its 63rd-percentile risk score.
What "at risk" means for the buildings here
USFS puts 69.9% of San Luis's 7,022 buildings in the Indirect exposure zone, versus 20.2% Direct and 9.9% Minimal — a place where the fire doesn't need to reach the structure directly for embers to. At 7,022 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.
San Luis against the rest of the country
Inside Arizona, San Luis sits at just the 28th percentile even though it scores 63rd nationally — the state's overall wildfire exposure is high enough to make this a relatively quiet corner of it. Among the 31,521 US communities USFS scores, San Luis ranks 11,648 for wildfire risk (1 is highest) and 2,444 by building count (1 is largest). Within Arizona alone, it ranks 318 of 441 places by risk. See the full county-by-county picture for Arizona on its state page.
San Luis and the insurance market
At the 63rd percentile nationally, San Luis 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.
What would actually reduce this score
Because 69.9% of San Luis'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
San Luis's 63rd-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 San Luis, see the exposure-zones guide.
