Alamo, CA
Alamo, CA's wildfire risk, in USFS's own numbers
Out of every US place USFS scores, Alamo lands at the 94th percentile for wildfire risk to structures — in USFS's highest wildfire-risk band nationally — a figure built from its 6,710 buildings, not the land around them. (Source: USFS's Wildfire Risk to Communities methodology.)
Separately from the risk score above, Alamo's burn probability — fire likelihood with no building count factored in — sits at the 94th percentile nationally.
What "at risk" means for the buildings here
Most of Alamo's buildings (54.2%) sit in the Indirect zone, where wind-blown embers rather than flame front are the mechanism USFS is scoring — ember-resistant vents and non-combustible roofing are the interventions this pattern favors, more than defensible space alone. At 6,710 buildings, this is a substantial built environment, so the shares below describe a real population of structures, not a handful of edge cases.
Where Alamo ranks
Alamo ranks lower within California (72nd percentile statewide) than its 94th national percentile suggests alone — a calmer spot in a state where wildfire risk generally runs high. Among the 31,521 US communities USFS scores, Alamo ranks 1,846 for wildfire risk (1 is highest) and 2,580 by building count (1 is largest). Within California alone, it ranks 447 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
Shopping for coverage in Alamo
Alamo 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 94th-percentile score like Alamo's can end up mattering for. More on the disclosure law.
What would actually reduce this score
Because 54.2% of Alamo's buildings sit in the Indirect zone, sealing the ember pathway (vents, roofing, gutters) is the intervention this page's data actually supports — see the home-hardening guide.
