How exposed is Arbon Valley to wildfire?
USFS scores Arbon Valley at the 95th national percentile for wildfire risk to structures (in USFS's highest wildfire-risk band nationally), a figure built from 608 real buildings rather than raw vegetation cover. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Arbon Valley at the 94th percentile, close to its 95th-percentile risk score.
Where Arbon Valley's buildings actually sit
Direct exposure dominates in Arbon Valley: 66.1% of its 608 buildings, versus 17.1% Indirect and 16.8% Minimal. Clearing space around a structure changes the outcome here more than any single building-material swap.
Where Arbon Valley ranks
There's little gap between Arbon Valley's 95th national percentile and its 80th percentile inside Idaho, which means the state comparison mostly confirms what the national score already shows. Among the 31,521 US communities USFS scores, Arbon Valley ranks 1,542 for wildfire risk (1 is highest) and 15,714 by building count (1 is largest). Within Idaho alone, it ranks 47 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 95th percentile nationally, Arbon Valley 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 Arbon Valley
