Only 2 points are in the Very High tier, so the highest-risk locations are concentrated rather than widespread. For countywide context, FEMA’s National Risk Index rates Solano County’s wildfire risk as "Relatively Moderate." FEMA also rates the county’s all-hazards risk as "Relatively High."

Communities ## Where in the county you are _matters most_ Among the largest cities, Fairfield has the highest middle wildfire-risk score at 45.5. Vacaville is lower at 36.4, and Vallejo is much lower at 16.7. Cordelia stands out at 43.7, close to Fairfield’s level. Suisun City is 23.9 and Benicia is 22.4, both in a lower range than Fairfield and Cordelia. Dixon and Rio Vista are on the lower side as well, at 18.9 and 19.9. So within Solano County, communities cluster at very different risk levels.

Population comes from the community's own record where the source carries one. Terrain & fuels ## Terrain, vegetation and _fuels_ Terrain contributes to these differences. Terrain scores range from 5.0 in Vallejo to 65.0 near Vacaville, with a middle value of 20.0. Vegetation and fuels show a wider middle level than terrain. Scores run from 5.0 in Vallejo to 80.0 near Vacaville, with a county middle value of 40.0. 20 median terrain score (max 65 near Vacaville) 40 median vegetation & fuels score (max 80 near Vacaville) Fire weather ## Fire weather across _Solano County_ Fire weather was measured across the county and is consistently elevated in score. It ranges from 60.2 near Vallejo to 68.5 near Rio Vista, with a middle value of 68.0. A separate USFS county product lists mean annual burn probability as 0.48% and a 90th-percentile cell value of 1.09%. Those are burn-probability figures, not local fire-weather scores. That same USFS product indicates 70.7% of the county can burn, with a mean conditional flame length of 3.18 feet. 60.2 lowest fire-weather score — near Vallejo 68.5 highest fire-weather score — near Rio Vista What drives it ## Which part of the risk _moves_, and which doesn't Risk is not uniform across Solano County. Vallejo sits at the low end of the scored range at 6.7, while the highest scored location is near Vacaville at 82.6. Among named communities, Fairfield has a higher middle score at 45.5, and Cordelia is close at 43.7. Vallejo is much lower at 16.7. Vacaville’s middle score is 36.4, which is above Suisun City at 23.9 and Benicia at 22.4. This spread shows why neighborhood-level differences matter inside the same county. Each bar is what one part of the score covers across Solano 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.

CAL FIRE has no mapped Fire Hazard Severity Zone at **3** of the 158 sampled points — the zones cover Local Responsibility Areas. At **2** of them the USFS grid above supplied the hazard reading instead; at the remaining 1 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 90%. Scores are 0–100 and comparable within the county, not across states. For a property ## What a county range means for _one address_ At the property-area level, hazard-zone scores are low in many scored places but can jump in specific locations. The middle hazard-zone score is 10.0, the minimum is 10.0 in Benicia, and the maximum reaches 90.0 in Cordelia. Fire-history scores are also uneven. The middle value is 5.0, but the highest scored location near Vacaville reaches 95.0 while Vallejo is at 5.0. For a homeowner, buyer, or agent, this means two addresses in the same county can sit in very different wildfire-risk settings because terrain, fuels, hazard-zone level, and fire history do not line up the same way everywhere. Across 158 sampled points in Solano County, the score runs from 6.7 to 82.6 — two neighbouring parcels can sit in different tiers.
