Johnsburg, IL
Johnsburg, IL's wildfire risk, in USFS's own numbers
Johnsburg sits at the 25th 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 3,155 counted buildings, not vegetation cover alone. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Johnsburg at the 26th national percentile — 1 points above its risk-to-structures score, a gap driven by how much is actually built there.
What "at risk" means for the buildings here
Most of Johnsburg's buildings (69% of 3,155) 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.
Where Johnsburg ranks
Compare Johnsburg's two percentiles: 71st within Illinois, only 25th nationally — a gap of 46 points that marks it as unusually exposed for its own state.

Within Illinois alone, it ranks 420 of 1,445 places by risk. See the full county-by-county picture for Illinois on its state page.
Shopping for coverage in Johnsburg
At the 25th national percentile, Johnsburg rates moderate for wildfire risk — well short of the threshold where insurers have been withdrawing coverage, though comparing a quote costs nothing either way.
What would actually reduce this score
With 69% of buildings rated Minimal exposure, Johnsburg gets less benefit from structure hardening than a Direct- or Indirect-dominant place would — the home-hardening guide explains why the zone matters.
Where Johnsburg's figures come from
Every one of the two percentiles behind Johnsburg's 23,692-place national rank traces to USFS's Wildfire Risk to Communities dataset — see the methodology guide. The exposure-zones guide covers what Johnsburg's dominant minimal exposure actually means, with real examples from across the dataset.
