This page is built from the Contra Costa County data pack: risk samples on a grid across the county, of which 3 fell inside ZIP 94531. Scores are informational decision support — not a substitute for official evacuation orders, a fire-agency hazard determination, or an insurer's underwriting judgement, and never a measurement of any individual property.

A ZIP median is the middle of a neighbourhood. An address-level Satelife report shows where in that spread your property actually sits — PDF, per-layer score, and a prioritized mitigation plan.
