Edison, CA
How exposed is Edison to wildfire?
Edison sits at the 86th 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 191 counted buildings, not vegetation cover alone. (Source: USFS's Wildfire Risk to Communities methodology.)
Separately from the risk score above, Edison's burn probability — fire likelihood with no building count factored in — sits at the 87th percentile nationally.
Where Edison's buildings actually sit
Indirect exposure is dominant in Edison (86.4% of 191 buildings): far enough from burnable vegetation to avoid flame contact, close enough for wind-blown embers. Only 13.6% sit in the Direct zone.
Where Edison ranks
Inside California, Edison sits at just the 52nd percentile even though it scores 86th nationally — the state's overall wildfire exposure is high enough to make this a relatively quiet corner of it. Among the 31,521 US communities USFS scores, Edison ranks 4,462 for wildfire risk (1 is highest) and 25,183 by building count (1 is largest). Within California alone, it ranks 755 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
What this risk score means for insurance
Edison sits in California, one of two states that legally require a wildfire-risk disclosure at sale. California's FAIR Plan, the state's insurer of last resort, ended 2025 with 668,609 residential policies after adding 21,859 in Q4 alone — the kind of market shift a 86th-percentile score like Edison's can end up mattering for.

Lowering exposure, not just insuring around it
With ember exposure the dominant pattern in Edison (86.4% Indirect), vent screens and roofing material tend to matter more than lot clearing alone. The home-hardening guide covers both.
More on how this number was built
Edison's 86th-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. For more on what indirect exposure implies beyond Edison, see the exposure-zones guide.
