Wildfire risk in Yuma County spans a wide range in the places we scored, from 15.0 in Somerton to 80.0 near Tacna, with a county middle point of 45.0. Most scored places fall in the Moderate tier (110 points), with fewer in High (47 points).
We scored 160 points across Yuma County on the same 0–100 scale a Satelife address report uses, and they do not land in one place. 1% of them come out Very High, while 1% are Low. Which end your own parcel sits at is not something a county map can tell you.
FEMA NRI also rates Yuma County: all-hazards risk Relatively Moderate · social vulnerability Relatively High · community resilience Very Low · annualised wildfire frequency 0.0005.

Among the larger communities shown, San Luis has a higher typical wildfire risk score at 48.3 than Yuma at 37.7. Fortuna Foothills and Wellton are both at 38.5.
Several smaller places are also on the higher side, including Avenue B & C at 55.0 and Cocopah at 48.0. Gadsden is 43.8, while Dateland is 36.1.
These are place-level patterns, not a single value for every property in town boundaries.
The score is the median of the sampled points nearest that community — a community-scale indicator, not a score for any individual property in it. Population comes from the community's own record where the source carries one.
Terrain-related risk runs from 20.0 near Fortuna Foothills up to 65.0 in Fortuna Foothills, with a middle value of 40.0 countywide in the places scored.
Vegetation and fuels are elevated in much of the county: the middle value is 80.0, with a low of 20.0 in Yuma and a high of 80.0 in unincorporated Yuma County.

Fire weather was not measured at the sampled points in Yuma County. The other four indicators on this page were, and the bars below show what they found.
Risk is not uniform across Yuma County. The highest scored location is near Tacna at 80.0, while the lowest is in Somerton at 15.0.
Across the four address-style tiers, Moderate appears most often, while Very High appears only once among the places scored. This points to mostly mid-range risk with a smaller set of higher-risk pockets.
At the community level, scores also spread out: Avenue B & C is at 55.0, while Somerton and Tacna are both at 33.8.
Each bar is what one part of the score covers across Yuma 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.
The tick on each bar is the middle value. Tier boundaries — Moderate at 25, High at 50, Very High at 75 — are the faint lines behind them.

CAL FIRE has no mapped Fire Hazard Severity Zone at 160 of the 160 sampled points — the zones cover Local Responsibility Areas, and most of this county is state or federal land. At 70 of them the USFS grid above supplied the hazard reading instead; at the remaining 90 the hazard weight is renormalised away rather than scored as low.
160 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 60%. Scores are 0–100 and comparable within the county, not across states.
Two mapped factors help explain why nearby properties can differ: hazard zone and local fire history. Hazard-zone values are low to moderate in this county, with a middle of 10.0 and a high of 45.5, both in unincorporated Yuma County.
Fire-history values are low in many places but can spike: the middle value is 5.0, while the high reaches 95.0 in Cocopah. That contrast is associated with sharper property-to-property differences in some areas.
For a specific home, use the exact location result and then compare it to nearby blocks, because county and town summaries can hide street-level changes.
