Siren, WI
How exposed is Siren to wildfire?
USFS's Wildfire Risk to Communities model puts Siren at the 52nd national percentile for risk to structures, modestly above the national average for wildfire risk — a score built from 693 actual buildings. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Siren at the 51st percentile, close to its 52nd-percentile risk score.
What "at risk" means for the buildings here
56.4% of Siren's 693 buildings fall in USFS's Indirect exposure zone — ember cast rather than direct flame — against 41.9% Direct and 1.7% Minimal. Vent screens and roofing material matter more here than lot clearing alone.
Where Siren ranks
Siren's 99th-percentile standing inside Wisconsin outpaces its 52nd 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, Siren ranks 15,303 for wildfire risk (1 is highest) and 14,745 by building count (1 is largest). Within Wisconsin alone, it ranks 11 of 808 places by risk. See the full county-by-county picture for Wisconsin on its state page.
Siren and the insurance market
Siren's elevated rating (52nd percentile nationally) sits outside the range where wildfire risk alone reshapes an insurance market — still, a homeowner here loses nothing by comparing rates.
Lowering exposure, not just insuring around it
Siren's 56.4% Indirect-exposure share points at embers, not flame contact, as the main pathway — ember-resistant vents and non-combustible roofing rank ahead of defensible space here. Detail in the home-hardening guide.
