There were 127 High locations and 27 Very High locations.\n\nOnly a small number of scored locations were below High: 4 were Moderate, and 0 were Low.\n\nFEMA’s National Risk Index rates Calaveras County’s wildfire risk as Relatively High, and its wildfire expected annual loss as Relatively High.\n\nFire record\n\n## Where the fires _actually were_\n\nThe largest fire listed for the county is the Butte fire in 2015, at 70,847 acres. It also destroyed 921 structures.\n\nThe most recent large fire is the Gann fire in 2026, at 10,339 acres.\n\nSince 1984, fires have burned 213,626 acres in the county. That equals 32.4% of the county, and 181 fire perimeters are listed over that period.\n\n![Butte Fire (2015) in Calaveras County, California - The original finding aid described this as: Date Taken: 2015-10-07 01:24:20 UTC Photographer name: Adam DuBrowa City/State: McClel](/images/wildfire-risk/calaveras-county/photos/calaveras-enterprise-reporter-travis-traborek-gets-a-look-at.webp)\n\n**Butte Fire, 2015** — Calaveras County.

West Point is also high at 71.4, and Mokelumne Hill is 70.6.\n\nMurphys (69.7) and Calaveritas (69.0) are close behind, while Angels Camp is lower at 65.1.\n\nArnold is 64.4 and Avery is 65.0.

Population comes from the community's own record where the source carries one.\n\nTerrain & fuels\n\n## Terrain, vegetation and _fuels_\n\nTerrain scores vary from 20.0 near San Andreas to 65.0 at Angels Camp, with a county middle value of 55.0.\n\nVegetation and fuels scores run from 31.0 at Angels Camp to 80.0 at Calaveritas, with a middle value of 70.0.\n\nPast fire activity is also a strong part of the county pattern: the fire-history score ranges from 5.0 at Angels Camp to 95.0 near Angels Camp, with a middle value of 80.0.\n\n55 median terrain score (max 65 near Angels Camp)\n\n70 median vegetation & fuels score (max 80 near Calaveritas)\n\n![LANDFIRE existing vegetation type map of Calaveras County, California, with the county boundary outlined](/images/wildfire-risk/calaveras-county/generated/calaveras-county-fuels.webp)\n\nLANDFIRE existing vegetation type across Calaveras County — the same fuel data that feeds the vegetation layer of a Satelife property report.\n\nFire weather\n\n## Fire weather across _Calaveras County_\n\nFire-weather scores were measured across the county and are relatively tight compared with other factors. They range from 53.5 near Mokelumne Hill to 62.5 near Arnold, with a middle value of 54.4.\n\nA separate USFS Wildfire Risk to Communities product reports a mean annual burn probability of 1.39% and a 90th-percentile cell burn probability of 3.10%.\n\nThat same USFS product indicates 97.2% of the county can burn and reports a mean conditional flame length of 7.41 feet.\n\n53.5 lowest fire-weather score — near Mokelumne Hill\n\n62.5 highest fire-weather score — near Arnold\n\nWhat drives it\n\n## Which part of the risk _moves_, and which doesn't\n\nRisk is not uniform from one part of the county to another. The highest scored location is Mokelumne Hill at 81.1, while the lowest is near San Andreas at 37.3.\n\nCommunity-level scores also vary. San Andreas is at 73.1, while Arnold is at 64.4.\n\nWest Point (71.4) and Mokelumne Hill (70.6) sit toward the higher end of community scores, while Angels Camp is lower at 65.1.\n\nEach bar is what one part of the score covers across Calaveras 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 Angels Camp\n\nVegetation & fuels\n\n31–80 highest near Calaveritas\n\nHazard zone\n\n10–92.8 highest near Arnold\n\nFire history\n\n5–95 highest near Angels Camp\n\nFire weather\n\n53.5–62.5 highest near Arnold\n\nOverall score\n\n37.3–81.1 highest near Mokelumne Hill\n\nThe tick on each bar is the middle value.

At **34** of them the USFS grid above supplied the hazard reading instead.\n\n158 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 100%. 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\nProperty-specific details, such as a home’s roof type or defensible-space condition, were not measured at all in these county scores.\n\nWhat is measured does include mapped wildfire hazard-zone conditions. In that layer, scored locations run from 10.0 in San Andreas to 92.8 in Arnold, with a middle value of 90.0.\n\nFor county-wide context, FEMA’s National Risk Index rates Calaveras County’s wildfire risk as Relatively High, while its all-hazards risk rating is Relatively Moderate and its community resilience rating is Relatively Low.\n\nAcross 158 sampled points in Calaveras County, the score runs from 37.3 to 81.1 — two neighbouring parcels can sit in different tiers.
