Twin Falls, ID
How exposed is Twin Falls to wildfire?
Twin Falls's 19,368 buildings earn a 91st-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, Twin Falls's burn probability — fire likelihood with no building count factored in — sits at the 91st percentile nationally.
What "at risk" means for the buildings here
Only 6.3% of Twin Falls's 19,368 buildings carry Direct exposure and 8.2% carry Indirect; the remaining 85.5% are Minimal, which shifts the risk driving this page's score toward the surrounding landscape rather than any one structure. At 19,368 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.
How Twin Falls compares
Inside Idaho, Twin Falls sits at just the 68th percentile even though it scores 91st nationally — the state's overall wildfire exposure is high enough to make this a relatively quiet corner of it. Among the 31,521 US communities USFS scores, Twin Falls ranks 2,953 for wildfire risk (1 is highest) and 734 by building count (1 is largest). Within Idaho alone, it ranks 75 of 232 places by risk. See the full county-by-county picture for Idaho on its state page.
Twin Falls and the insurance market
Twin Falls's very high rating (91st 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
Even with 85.5% of Twin Falls outside USFS's Direct and Indirect zones, basic hardening — gutter maintenance, ember-resistant vents — is inexpensive relative to the regional burn-probability risk noted above. Details in the home-hardening guide.
More on how this number was built
Twin Falls's 91st-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. For more on what minimal exposure implies beyond Twin Falls, see the exposure-zones guide.
