Union Hill, IL
How exposed is Union Hill to wildfire?
Out of every US place USFS scores, Union Hill lands at the 1st percentile for wildfire risk to structures — among the lower wildfire-risk places nationally — a figure built from its 58 buildings, not the land around them. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Union Hill at the 1st percentile, close to its 1st-percentile risk score.
What "at risk" means for the buildings here
Most of Union Hill's buildings (91.4% of 58) 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.
Union Hill against the rest of the country
Union Hill's risk sits at a similar level relative to Illinois (6th percentile statewide) as it does nationally (1st) — this place isn't unusual for its own state either way. Among the 31,521 US communities USFS scores, Union Hill ranks 31,357 for wildfire risk (1 is highest) and 30,706 by building count (1 is largest). Within Illinois alone, it ranks 1,369 of 1,445 places by risk. See the full county-by-county picture for Illinois on its state page.
What this risk score means for insurance
At the 1st national percentile, Union Hill rates low for wildfire risk — well short of the threshold where insurers have been withdrawing coverage, though comparing a quote costs nothing either way.
Hardening a home in Union Hill
Even with 91.4% of Union Hill 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.
