Communities ## Where in the county you are _matters most_ Mammoth Lakes is the largest community listed (population 8,234), and its middle wildfire-risk score is 55.1. Several smaller communities score somewhat higher, including Crowley Lake at 58.6 and Walker at 60.2. June Lake (57.6), Benton (57.4), and Lee Vining (56.9) are in a similar range. Bridgeport is lower at 53.4. Chalfant stands out on the lower end among listed communities at 44.0. So within one county, community-level wildfire risk can still differ noticeably.

Population comes from the community's own record where the source carries one. Terrain & fuels ## Terrain, vegetation and _fuels_ Terrain is a meaningful part of the county pattern. Terrain scores range from 30.0 in Crowley Lake to 65.0 in Chalfant, with a middle value of 55.0. Vegetation and fuels are generally elevated in the scored locations. The middle score is 75.8, with the high end at 80.0 near Chalfant and a low of 5.0 in Lee Vining. Hazard-zone scores also vary sharply by place, from 10.0 in Crowley Lake up to 90.0 in Walker. That contributes to why local wildfire risk can change quickly across the county. 55 median terrain score (max 65 near Chalfant) 75.8 median vegetation & fuels score (max 80 near Chalfant) Fire weather ## Fire weather across _Mono County_ Fire-weather scores were measured across the county and are fairly tight compared with other factors. They run from 54.9 in Lee Vining to 65.5 near Benton, with a middle value of 55.1. A separate national model estimates mean annual burn probability at 0.41%, with a 90th-percentile cell value of 1.03%. This is a burn-probability measure, not a fire-weather score. 54.9 lowest fire-weather score — near Lee Vining 65.5 highest fire-weather score — near Benton What drives it ## Which part of the risk _moves_, and which doesn't Risk is not uniform from one part of Mono County to another. The highest scored location is Walker at 76.9, while the lowest is near Lee Vining at 28.0. That spread shows up in town-level patterns too. Walker has a community middle score of 60.2, while Chalfant is lower at 44.0. Even where countywide ratings look moderate, local differences are large enough that nearby communities can sit in different risk tiers. Each bar is what one part of the score covers across Mono 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.

Source: USFS Wildfire Risk to Communities v2.0 (ImageServer, county extent). CAL FIRE has no mapped Fire Hazard Severity Zone at **128** of the 158 sampled points — the zones cover Local Responsibility Areas, and most of this county is state or federal land. At **111** of them the USFS grid above supplied the hazard reading instead; at the remaining 17 the hazard weight is renormalised away rather than scored as low. 158 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. For a property ## What a county range means for _one address_ For countywide context, FEMA’s National Risk Index rates Mono County’s wildfire risk as Relatively Moderate and wildfire expected annual loss as Relatively Moderate. FEMA also rates the county’s all-hazards risk as Relatively Low. At the same time, county-level ratings do not erase local variation. In the scored locations, there are 92 High points and 2 Very High points, so property-level and neighborhood-level differences matter in Mono County. FEMA’s National Risk Index also rates social vulnerability as Relatively Low and community resilience as Relatively High. Those are countywide ratings, not ratings for a specific town or property. Across 158 sampled points in Mono County, the score runs from 28 to 76.9 — two neighbouring parcels can sit in different tiers. A county number is the middle of that spread; it says nothing about which end yours is at.
