Harmony Grove, CA
Harmony Grove wildfire risk explained
Harmony Grove sits at the 90th percentile nationally for wildfire risk to structures — in USFS's highest wildfire-risk band nationally — per USFS's Wildfire Risk to Communities model, built from its 862 counted buildings, not vegetation cover alone. (Source: USFS's Wildfire Risk to Communities methodology.)
Separately from the risk score above, Harmony Grove's burn probability — fire likelihood with no building count factored in — sits at the 88th percentile nationally.
Where Harmony Grove's buildings actually sit
56.8% of Harmony Grove's 862 buildings fall in USFS's Indirect exposure zone — ember cast rather than direct flame — against 43.2% Direct and 0% Minimal. Vent screens and roofing material matter more here than lot clearing alone.
Where Harmony Grove ranks
Inside California, Harmony Grove sits at just the 60th percentile even though it scores 90th nationally — the state's overall wildfire exposure is high enough to make this a relatively quiet corner of it.

Within California alone, it ranks 624 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
