Sun Prairie, WI
How exposed is Sun Prairie to wildfire?
Sun Prairie 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 10,045 counted buildings, not vegetation cover alone. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Sun Prairie at the 33rd national percentile — 1 points above its risk-to-structures score, a gap driven by how much is actually built there.
Sun Prairie's building exposure, zone by zone
88.9% of Sun Prairie's 10,045 buildings sit in USFS's Minimal exposure zone, with only 11.1% rated Direct — risk here comes from regional burn probability more than proximity to burnable vegetation at the structure itself. At 10,045 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.
Sun Prairie against the rest of the country
Compare Sun Prairie's two percentiles: 71st within Wisconsin, only 32nd nationally — a gap of 39 points that marks it as unusually exposed for its own state. Among the 31,521 US communities USFS scores, Sun Prairie ranks 21,450 for wildfire risk (1 is highest) and 1,598 by building count (1 is largest). Within Wisconsin alone, it ranks 233 of 808 places by risk. See the full county-by-county picture for Wisconsin on its state page.
Shopping for coverage in Sun Prairie
At the 32nd national percentile, Sun Prairie rates moderate 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 88.9% of Sun Prairie 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.
