Union Grove, WI
Union Grove wildfire risk explained
Union Grove sits at the 12th 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 1,900 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 Union Grove at the 12th percentile, close to its 12th-percentile risk score.
Where Union Grove's buildings actually sit
Only 10.4% of Union Grove's 1,900 buildings carry Direct exposure and 0% carry Indirect; the remaining 89.6% are Minimal, which shifts the risk driving this page's score toward the surrounding landscape rather than any one structure.
How Union Grove compares
Union Grove scores 12th nationally and 10th within Wisconsin — close enough that its state context doesn't change the picture the national number already gives. Among the 31,521 US communities USFS scores, Union Grove ranks 27,754 for wildfire risk (1 is highest) and 7,766 by building count (1 is largest). Within Wisconsin alone, it ranks 730 of 808 places by risk. See the full county-by-county picture for Wisconsin on its state page.
Union Grove and the insurance market
At the 12th national percentile, Union Grove rates low for wildfire risk — well short of the threshold where insurers have been withdrawing coverage, though comparing a quote costs nothing either way.
Lowering exposure, not just insuring around it
Even with 89.6% of Union 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.
