Twin Grove, IL
How exposed is Twin Grove to wildfire?
Twin Grove sits at the 3rd percentile nationally for wildfire risk to structures — among the lower wildfire-risk places nationally — per USFS's Wildfire Risk to Communities model, built from its 864 counted buildings, not vegetation cover alone. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Twin Grove at the 3rd percentile, close to its 3rd-percentile risk score.
What "at risk" means for the buildings here
Most of Twin Grove's buildings (59.6% of 864) fall outside USFS's Direct and Indirect zones entirely — that doesn't zero out the score above, it means the risk is regional, not structure-by-structure.
Twin Grove against the rest of the country
Twin Grove's 21st-percentile standing inside Illinois outpaces its 3rd national percentile — this is a hotter spot than most of its own state, even though the state as a whole runs cooler nationally. Among the 31,521 US communities USFS scores, Twin Grove ranks 30,507 for wildfire risk (1 is highest) and 13,037 by building count (1 is largest). Within Illinois alone, it ranks 1,148 of 1,445 places by risk. See the full county-by-county picture for Illinois on its state page.
Twin Grove and the insurance market
Twin Grove's low wildfire rating (3rd percentile) isn't the kind of score driving the carrier pullback making news in the highest-risk Western markets — but a standard homeowners quote is still worth comparing on its own terms.
What would actually reduce this score
Even with 59.6% of Twin Grove 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.
