What "at risk" means for the buildings here

Dunnigan against the rest of the country
Inside California, Dunnigan sits at just the 60th percentile even though it scores 89th nationally — the state's overall wildfire exposure is high enough to make this a relatively quiet corner of it.

Within California alone, it ranks 628 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
Dunnigan and the insurance market

Hardening a home in Dunnigan
