Marana, AZ
How exposed is Marana to wildfire?
USFS scores Marana at the 85th national percentile for wildfire risk to structures (in USFS's highest wildfire-risk band nationally), a figure built from 22,189 real buildings rather than raw vegetation cover. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Marana at the 83rd national percentile — 2 points below its risk-to-structures score, a gap driven by how much is actually built there.
Where Marana's buildings actually sit
53.3% of Marana's 22,189 buildings fall in USFS's Indirect exposure zone — ember cast rather than direct flame — against 36.3% Direct and 10.4% Minimal. Vent screens and roofing material matter more here than lot clearing alone. At 22,189 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.
How Marana compares
Marana's 85th national percentile looks worse in isolation than its 55th ranking inside Arizona does — this place is on the milder end for its own state, by 30 points. Among the 31,521 US communities USFS scores, Marana ranks 4,809 for wildfire risk (1 is highest) and 613 by building count (1 is largest). Within Arizona alone, it ranks 200 of 441 places by risk. See the full county-by-county picture for Arizona on its state page.
Marana and the insurance market
Marana's 85th-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.
Hardening a home in Marana
Marana's 53.3% Indirect-exposure share points at embers, not flame contact, as the main pathway — ember-resistant vents and non-combustible roofing rank ahead of defensible space here. Detail in the home-hardening guide.
Where Marana's figures come from
Every one of the two percentiles behind Marana's 4,809-place national rank traces to USFS's Wildfire Risk to Communities dataset — see the methodology guide. The exposure-zones guide covers what Marana's dominant indirect exposure actually means, with real examples from across the dataset.
