Spring Grove, IL
How exposed is Spring Grove to wildfire?
Spring Grove sits at the 32nd percentile nationally for wildfire risk to structures — close to the middle of USFS's national wildfire-risk range — per USFS's Wildfire Risk to Communities model, built from its 2,423 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 Spring Grove at the 33rd percentile, close to its 32nd-percentile risk score.
Where Spring Grove's buildings actually sit
2,423 buildings are counted in Spring Grove, and 77.8% of them sit in USFS's Direct exposure zone — flame contact, not just ember cast, is the live possibility for most of them, against 20.7% rated Minimal.

Shopping for coverage in Spring Grove
Spring Grove's moderate wildfire rating (32nd 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
Because Direct exposure dominates in Spring Grove (77.8%), the highest-leverage fix is defensible space, not roofing or vents alone — covered in the home-hardening guide.
More on how this number was built
