Mountain Home AFB, ID
Mountain Home AFB wildfire risk explained
Mountain Home AFB sits at the 99th percentile nationally for wildfire risk to structures — in USFS's highest wildfire-risk band nationally — per USFS's Wildfire Risk to Communities model, built from its 1,280 counted buildings, not vegetation cover alone. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Mountain Home AFB at the 100th national percentile — 1 points above its risk-to-structures score, a gap driven by how much is actually built there.
What "at risk" means for the buildings here
Most of Mountain Home AFB's buildings (87%) sit in the Indirect zone, where wind-blown embers rather than flame front are the mechanism USFS is scoring — ember-resistant vents and non-combustible roofing are the interventions this pattern favors, more than defensible space alone.
Mountain Home AFB against the rest of the country
Mountain Home AFB's risk sits at a similar level relative to Idaho (98th percentile statewide) as it does nationally (99th) — this place isn't unusual for its own state either way. Among the 31,521 US communities USFS scores, Mountain Home AFB ranks 289 for wildfire risk (1 is highest) and 10,195 by building count (1 is largest). Within Idaho alone, it ranks 5 of 232 places by risk. See the full county-by-county picture for Idaho on its state page.
Mountain Home AFB and the insurance market
Mountain Home AFB's 99th-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
With ember exposure the dominant pattern in Mountain Home AFB (87% Indirect), vent screens and roofing material tend to matter more than lot clearing alone. The home-hardening guide covers both.
