FEMA also rates the county’s all-hazards risk as Very High.\n\nAnother countywide view points the same way: 7.1% of the county has burned since 1984, and 87.5% of the county is in areas that can burn.\n\nFire record\n\n## Where the fires _actually were_\n\nSince 1984, San Bernardino County has had 448 fire perimeters and 915,062 acres burned. That history is part of why risk is a practical issue for owners, buyers, and agents.\n\nThe largest fire listed here is the York fire in 2023 at 93,078 acres. The most recent large fire is Gold (2025).\n\nThe Old fire (2003) is also a key event in this county record: it burned 91,428 acres and destroyed 1,003 structures.\n\n![York Fire (2023) in San Bernardino County, California - York Fire glowing in the background on the evening of 7-29-23 in San Bernardino Co.

Rancho Cucamonga is higher at 26.7, and Victorville is higher still at 45.3.\n\nSeveral mountain and high-desert communities score much higher, including Wrightwood at 74.7 and Running Springs at 71.4.

Population comes from the community's own record where the source carries one.\n\nTerrain & fuels\n\n## Terrain, vegetation and _fuels_\n\nFire weather was not measured at all in this county view.\n\nWhat was measured shows strong terrain and fuel influence. Terrain scores run from 20.0 in unincorporated San Bernardino County to 65.0 in Yucca Valley, with a middle value of 65.0.\n\nVegetation and fuels also vary: the lowest scored place is San Bernardino at 20.0, while Joshua Tree reaches 80.0, with a middle value of 74.3.\n\n65 median terrain score (max 65 near Yucca Valley)\n\n74.3 median vegetation & fuels score (max 80 near Joshua Tree)\n\n![LANDFIRE existing vegetation type map of San Bernardino County, California, with the county boundary outlined](/images/wildfire-risk/san-bernardino-county/generated/san-bernardino-county-fuels.webp)\n\nLANDFIRE existing vegetation type across San Bernardino County — the same fuel data that feeds the vegetation layer of a Satelife property report.\n\nFire weather\n\n## Fire weather across _San Bernardino County_\n\nFire weather was not measured at the sampled points in San Bernardino County. The other four indicators on this page were, and the bars below show what they found.\n\nWhat drives it\n\n## Which part of the risk _moves_, and which doesn't\n\nRisk is not evenly distributed across the county. The lowest scored locations are at 16.7, while the highest scored location reaches 85.8.\n\nMost scored locations fall in the Moderate tier (107 points), followed by High (74 points). There are fewer points in Low (14) and Very High (7).\n\nIn plain terms, that means many areas sit in the middle, but there are still pockets at both ends of the risk scale.\n\nEach bar is what one part of the score covers across San Bernardino County, on the same 0–100 scale. A long bar is a part of the risk that depends on where you are; a short one is the same almost everywhere.\n\nTerrain\n\n20–65 highest near Yucca Valley\n\nVegetation & fuels\n\n20–80 highest near Joshua Tree\n\nHazard zone\n\n10–95 highest near Apple Valley\n\nFire history\n\n5–95 highest near Yucca Valley\n\nOverall score\n\n16.7–85.8 highest near Apple Valley\n\nThe tick on each bar is the middle value.

At **63** of them the USFS grid above supplied the hazard reading instead; at the remaining 53 the hazard weight is renormalised away rather than scored as low.\n\n202 sample points on a ~2.3 km grid, plus one at the centre of each community, weighted with the Satelife county profile v1 · median layer coverage 90%. Scores are 0–100 and comparable within the county, not across states.\n\nFor a property\n\n## What a county range means for _one address_\n\nAt property scale, two nearby locations can sit in very different risk conditions. Hazard zone scores run from 10.0 in Mentone up to 95.0 in Apple Valley.\n\nFire history intensity also ranges widely, from 5.0 in unincorporated San Bernardino County to 95.0 in Yucca Valley. These patterns are associated with why some neighborhoods score much higher than others.\n\nA separate countywide burn-probability view reports a mean annual burn probability of 0.40%, with a 90th-percentile cell value of 0.64%. This is a burn-probability measure, not fire weather.\n\nAcross 202 sampled points in San Bernardino County, the score runs from 16.7 to 85.8 — two neighbouring parcels can sit in different tiers.
