Wildfire risk in Sacramento County varies by location, but most places we scored sit in the lower-to-middle part of the range. Countywide, the scored range runs from 18.3 in Elk Grove to 65.3 in Rancho Murieta, with a midpoint of 26.3.
We scored 160 points across Sacramento County on the same 0–100 scale a Satelife address report uses, and they do not land in one place. 11% of them come out High, while 43% are Low. Which end your own parcel sits at is not something a county map can tell you.
FEMA NRI also rates Sacramento County: all-hazards risk Relatively High · social vulnerability Relatively Low · community resilience Relatively Moderate · annualised wildfire frequency 0.0034.

Sacramento, the largest city listed here (490,712 people), has a community median wildfire-risk score of 18.3. Elk Grove, the next largest listed city (166,913 people), is at 25.2.
Among smaller places, Rancho Murieta stands out at 52.0, while Rio Linda is 23.4 and Walnut Grove is 24.8.
These are community-level medians, so they describe the general pattern around each place, not every individual property on every street.
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 exposure is lower in flatter areas and higher near Rancho Murieta. Terrain scores run from 5.0 near Isleton to 40.0 in Rancho Murieta, with a midpoint of 20.0.
Vegetation and fuels show a wider climb: 20.0 in Elk Grove and up to 73.1 in Rancho Murieta, with a midpoint of 43.8.
Hazard-zone scoring is 10.0 in some lower-scored areas near Isleton and reaches 70.0 near Rancho Murieta.
Fire-history scoring runs from 5.0 to 95.0, with the highest value recorded near Isleton.
Fire weather was measured across the county and stays within a relatively tight band. Scores run from 62.3 in Galt to 69.2 in Isleton, with a midpoint of 62.7.
A separate modeled burn-probability product is available for Sacramento County, but it is not a fire-weather measure. It reports a mean annual burn probability of 0.26% and a 90th-percentile cell value of 0.55%.
That same modeled product indicates 68.3% of the county is in places that can burn, and reports a mean conditional flame length of 2.28 feet.
Differences between communities are noticeable. Rancho Murieta has the highest community median in this set at 52.0, while Sacramento is much lower at 18.3.
Other communities cluster closer to the county middle. Rancho Cordova is 28.8, Galt is 25.8, and Folsom is 25.3.
At the lower end of the community list, Citrus Heights is 18.4 and Isleton is 21.7. That spread is why two homes in different parts of the county can have very different wildfire-risk profiles.
Each bar is what one part of the score covers across Sacramento 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 2 of the 160 sampled points — the zones cover Local Responsibility Areas. At 2 of them the USFS grid above supplied the hazard reading instead.
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 100%. Scores are 0–100 and comparable within the county, not across states.
A separate property-condition measure was not measured at all for this county page.
What is available for property context is countywide risk information. FEMA’s National Risk Index rates Sacramento County’s wildfire risk and expected annual loss from wildfire as Relatively Moderate, with social vulnerability rated Relatively Low.
For broader context, FEMA rates county community resilience as Relatively Moderate. On the same countywide view, the modeled burn-probability product reports 0.26% mean annual burn probability.
