Glenns Ferry, ID
Glenns Ferry, ID's wildfire risk, in USFS's own numbers
Out of every US place USFS scores, Glenns Ferry lands at the 99th percentile for wildfire risk to structures — in USFS's highest wildfire-risk band nationally — a figure built from its 953 buildings, not the land around them. (Source: USFS's Wildfire Risk to Communities methodology.)
Separately from the risk score above, Glenns Ferry's burn probability — fire likelihood with no building count factored in — sits at the 99th percentile nationally.
Glenns Ferry's building exposure, zone by zone
Most of Glenns Ferry's buildings (85.7%) 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.
Glenns Ferry against the rest of the country
Glenns Ferry's risk sits at a similar level relative to Idaho (94th 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, Glenns Ferry ranks 479 for wildfire risk (1 is highest) and 12,285 by building count (1 is largest). Within Idaho alone, it ranks 15 of 232 places by risk. See the full county-by-county picture for Idaho on its state page.
What this risk score means for insurance
Glenns Ferry'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.
Hardening a home in Glenns Ferry
With ember exposure the dominant pattern in Glenns Ferry (85.7% Indirect), vent screens and roofing material tend to matter more than lot clearing alone. The home-hardening guide covers both.
