Janesville, IA
Janesville, IA's wildfire risk, in USFS's own numbers
USFS scores Janesville at the 40th national percentile for wildfire risk to structures (close to the middle of USFS's national wildfire-risk range), a figure built from 651 real buildings rather than raw vegetation cover. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Janesville at the 40th national percentile — 0 points above its risk-to-structures score, a gap driven by how much is actually built there.
Where Janesville's buildings actually sit
651 buildings are counted in Janesville, and 83.7% of them are Indirect exposure — ember-driven risk rather than the 15.7% in Direct exposure or the 0.6% rated Minimal.
