CAL FIRE has no mapped Fire Hazard Severity Zone at 37 of the 160 sampled points — the zones cover Local Responsibility Areas. At 36 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.

For a property

What a county range means for one address

For property-level context, hazard-zone scores are often high in this county. They range from 10.0 near Corning to 99.1 in unincorporated Tehama County, with a middle value of 75.9.

Past fire activity also varies sharply by location. Fire-history scores run from 5.0 near Paskenta to 95 in Vina, with a middle value of 50.0.

At county scale, the USFS model indicates 96.5% of Tehama County is in areas that can burn. That helps explain why two homes in the same county can still face very different wildfire risk scores.

Across 160 sampled points in Tehama County, the score runs from 22.3 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.
