How exposed is Willowbrook (DuPage) to wildfire?
USFS's Wildfire Risk to Communities model puts Willowbrook (DuPage) at the 21st national percentile for risk to structures, close to the middle of USFS's national wildfire-risk range — a score built from 2,276 actual buildings. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Willowbrook (DuPage) at the 24th national percentile — 4 points above its risk-to-structures score, a gap driven by how much is actually built there.
Where Willowbrook (DuPage)'s buildings actually sit
Most of Willowbrook (DuPage)'s buildings (95.6% of 2,276) 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.
