Midvale, ID
How exposed is Midvale to wildfire?
USFS scores Midvale at the 95th national percentile for wildfire risk to structures (in USFS's highest wildfire-risk band nationally), a figure built from 257 real buildings rather than raw vegetation cover. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Midvale at the 96th 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
58.8% of Midvale's 257 buildings fall in USFS's Indirect exposure zone — ember cast rather than direct flame — against 41.3% Direct and 0% Minimal. Vent screens and roofing material matter more here than lot clearing alone.
Where Midvale ranks
Midvale ranks lower within Idaho (78th percentile statewide) than its 95th national percentile suggests alone — a calmer spot in a state where wildfire risk generally runs high. Among the 31,521 US communities USFS scores, Midvale ranks 1,632 for wildfire risk (1 is highest) and 22,913 by building count (1 is largest). Within Idaho alone, it ranks 50 of 232 places by risk. See the full county-by-county picture for Idaho on its state page.
Midvale and the insurance market
Midvale's very high rating (95th percentile) puts it among the places where the national carrier-pullback trend is most relevant — not a guarantee of a coverage problem, but a reason to shop rather than assume.
What would actually reduce this score
Midvale's 58.8% 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.
More on how this number was built
Midvale's 95th-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. For more on what indirect exposure implies beyond Midvale, see the exposure-zones guide.
