Sun Valley, ID
Sun Valley, ID's wildfire risk, in USFS's own numbers
Sun Valley's 1,537 buildings earn a 90th-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.)
Separately from the risk score above, Sun Valley's burn probability — fire likelihood with no building count factored in — sits at the 88th percentile nationally.
Sun Valley's building exposure, zone by zone
1,537 buildings are counted in Sun Valley, and 59.1% of them sit in USFS's Direct exposure zone — flame contact, not just ember cast, is the live possibility for most of them, against 0% rated Minimal.
How Sun Valley compares
Sun Valley ranks lower within Idaho (67th percentile statewide) than its 90th national percentile suggests alone — a calmer spot in a state where wildfire risk generally runs high. Among the 31,521 US communities USFS scores, Sun Valley ranks 3,117 for wildfire risk (1 is highest) and 8,999 by building count (1 is largest). Within Idaho alone, it ranks 78 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 90th percentile nationally, Sun 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.
What would actually reduce this score
Because Direct exposure dominates in Sun Valley (59.1%), the highest-leverage fix is defensible space, not roofing or vents alone — covered in the home-hardening guide.
