A hazard class describes mapped hazard across an area. It is not a prediction about one house: homes in moderate zones burn and homes in very high zones survive, and what decides it is mostly the first five feet and the roof. Clearing is the part you control.
Hazard zones are read live from CAL FIRE, published on San Diego County's public GIS as the 2025 Fire Hazard Severity Zones; addresses are located by the US Census Bureau’s public geocoder. The official map is the City of Vista's own hazard-zone map.
