Arimo, ID
Arimo wildfire risk explained
Arimo's 232 buildings earn a 93rd-percentile wildfire-risk score nationally under USFS's model — in USFS's highest wildfire-risk band nationally. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Arimo at the 93rd national percentile — 0 points above its risk-to-structures score, a gap driven by how much is actually built there.
Where Arimo's buildings actually sit
62.5% of Arimo's 232 buildings fall in USFS's Indirect exposure zone — ember cast rather than direct flame — against 37.5% Direct and 0% Minimal. Vent screens and roofing material matter more here than lot clearing alone.
How Arimo compares
Arimo ranks lower within Idaho (72nd percentile statewide) than its 93rd national percentile suggests alone — a calmer spot in a state where wildfire risk generally runs high. Among the 31,521 US communities USFS scores, Arimo ranks 2,265 for wildfire risk (1 is highest) and 23,728 by building count (1 is largest). Within Idaho alone, it ranks 64 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
At the 93rd percentile nationally, Arimo carries the very 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.
Hardening a home in Arimo
Arimo's 62.5% 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 Arimo's figures come from
Arimo's 93rd-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. The exposure-zones guide covers what Arimo's dominant indirect exposure actually means, with real examples from across the dataset.
