Granite Hills's building exposure, zone by zone

Inside California, Granite Hills sits at just the 75th percentile even though it scores 96th nationally — the state's overall wildfire exposure is high enough to make this a relatively quiet corner of it.

Within California alone, it ranks 391 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
