Boron, CA
Boron, CA's wildfire risk, in USFS's own numbers
USFS scores Boron at the 46th national percentile for wildfire risk to structures (modestly above the national average for wildfire risk), a figure built from 1,421 real buildings rather than raw vegetation cover. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Boron at the 49th national percentile — 3 points above its risk-to-structures score, a gap driven by how much is actually built there.
Where Boron's buildings actually sit
1,421 buildings are counted in Boron, and 70% of them are Indirect exposure — ember-driven risk rather than the 30% in Direct exposure or the 0% rated Minimal.
Where Boron ranks
Boron's 46th national percentile looks worse in isolation than its 8th ranking inside California does — this place is on the milder end for its own state, by 38 points. Among the 31,521 US communities USFS scores, Boron ranks 16,976 for wildfire risk (1 is highest) and 9,530 by building count (1 is largest). Within California alone, it ranks 1,439 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
Shopping for coverage in Boron
Boron 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 46th-percentile score like Boron's can end up mattering for.

Lowering exposure, not just insuring around it
Boron's 70% Indirect-exposure share points at embers, not flame contact, as the main pathway — ember-resistant vents and non-combustible roofing rank ahead of defensible space here. Detail in the home-hardening guide.
More on how this number was built
Boron's 46th-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 Boron, see the exposure-zones guide.
