Lidderdale, IA
Lidderdale wildfire risk explained
Lidderdale's 190 buildings earn a 2nd-percentile wildfire-risk score nationally under USFS's model — among the lower wildfire-risk places nationally. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Lidderdale at the 2nd national percentile — 0 points below its risk-to-structures score, a gap driven by how much is actually built there.
What "at risk" means for the buildings here
Lidderdale rates 79% Minimal exposure against just 21.1% Direct and 0% Indirect — of 190 buildings counted, few sit close enough to burnable vegetation for USFS to flag them individually.
How Lidderdale compares
Lidderdale scores 2nd nationally and 2nd within Iowa — close enough that its state context doesn't change the picture the national number already gives. Among the 31,521 US communities USFS scores, Lidderdale ranks 31,019 for wildfire risk (1 is highest) and 25,241 by building count (1 is largest). Within Iowa alone, it ranks 998 of 1,017 places by risk. See the full county-by-county picture for Iowa on its state page.
Lidderdale and the insurance market
Lidderdale's low rating (2nd 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
With 79% of buildings rated Minimal exposure, Lidderdale gets less benefit from structure hardening than a Direct- or Indirect-dominant place would — the home-hardening guide explains why the zone matters.
