Half of Shasta County scores High or worse
We scored 162 points across Shasta County on the same 0–100 scale a Satelife address report uses, and they do not land in one place. 18% 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.

Terrain & fuels
Terrain, vegetation and fuels
Terrain contributes steady background exposure: terrain scores run from 40.0 up to 65.0, with the upper end seen at Shingletown.
Vegetation and fuels vary more, from 20.0 in Redding to 80.0 in unincorporated areas, with a middle value of 70.0.
State hazard-zone scoring is high in many places, with a middle value of 90.0, peaking at 96.0 near Bella Vista and dropping to 10.0 in Cottonwood.
Fire-history scoring ranges from 5.0 near Cottonwood to 95.0 in unincorporated areas, with a middle value of 60.0. Fire weather was not measured at all in this county summary.

What drives it
Which part of the risk moves, and which doesn't
Wildfire risk is not even from one part of the county to another. Cottonwood is the lowest named point at 20.0, while unincorporated Shasta County reaches 82.5.
Redding sits lower than many nearby communities at 39.1, while Shasta Lake is 67.2 and Bella Vista is 70.2.
By tier counts, High is the dominant tier in the places we scored (119 points), with another 29 in Very High. This pattern is associated with broad elevated exposure, not just a few isolated hotspots.
Each bar is what one part of the score covers across Shasta 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.

Independently of Satelife's layers, the USFS Wildfire Risk to Communities grid puts the county's mean annual burn probability at 1.25% (90th percentile cell: 2.89%), with a mean conditional flame length of 6.94 ft. 98% of the 27,106 grid cells inside the county carry burnable fuel at all.

CAL FIRE has no mapped Fire Hazard Severity Zone at 57 of the 162 sampled points — the zones cover Local Responsibility Areas. At 57 of them the USFS grid above supplied the hazard reading instead.
162 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
A separate national model from the U.S. Forest Service reports a mean annual burn probability of 1.25% for the county, with 2.89% in its higher-exposure cells.
That same model indicates 98.3% of the county can burn and reports a mean conditional flame length of 6.94 feet.
At the county scale, FEMA’s National Risk Index rates wildfire risk as "Relatively High" and expected annual wildfire loss as "Relatively High." FEMA rates social vulnerability and community resilience as "Relatively Moderate."
Across 162 sampled points in Shasta County, the score runs from
20 to 82.5 — 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.

ZIP codes we cover in Shasta County
Every one of the 36 ZIP areas that touch Shasta County — we run address-level
reports in all of them. They are grouped by the median score of the points we sampled inside
each, which is a neighbourhood-scale indicator and not a score for any
property: two homes in the same ZIP routinely land in different tiers.
