Summary
Portions of Corona including the Skyline Drive ridgeline, Sierra Del Oro hillsides, and parcels adjacent to Cleveland National Forest and Santiago Peak foothills are mapped as Very High Fire Hazard Severity Zones by CAL FIRE. Properties in these zones are subject to AB 38 disclosure, defensible space, and Chapter 7A building requirements.
The State Fire Marshal is mandated to classify lands within State Responsibility Areas into Fire Hazard Severity Zones (FHSZ). Fire Hazard Severity Zones fall into one of the following classifications: Moderate High Very High The California laws that require Fire Hazard Severity Zones include California Public Resources Code 4201-4204, California Code of Regulations Title 14, Section 1280 and California Government Code 51175-89. The Fire Hazard Severity Zone (FHSZ) maps are developed using a science-based and field-tested model that assigns a hazard score based on the factors that influence fire likelihood and fire behavior. Many factors are considered such as fire history, existing and potential fuel (natural vegetation), predicted flame length, blowing embers, terrain, and typical fire weather for the area. There are three levels of hazard in the State Responsibility Areas: moderate, high, and very high. Fire Hazard Severity Zone maps evaluate "hazard," not "risk". They are like flood zone maps, where lands are described in terms of the probability level of a particular area being inundated by floodwaters, and not specifically prescriptive of impacts. "Hazard" is based on the physical conditions that create a likelihood and expected fire behavior over a 30 to 50-year period without considering mitigation measures such as home hardening, recent wildfire, or fuel reduction efforts.
Full Breakdown
CAL FIRE has mapped substantial portions of southern and western Corona as Very High Fire Hazard Severity Zones (VHFHSZ) within the Local Responsibility Area, with adjacent State Responsibility Area lands extending into the Cleveland National Forest, Santa Ana Mountains, and Santiago Peak watershed. Affected Corona neighborhoods include the Skyline Drive ridgeline development, Sierra Del Oro hillsides above Green River Road, the Coronita unincorporated transition, properties along Foothill Parkway abutting open space, and hillside lots in the South Corona area near Cleveland National Forest. New construction or major remodels in mapped VHFHSZ areas must comply with California Building Code Chapter 7A (Materials and Construction Methods for Exterior Wildfire Exposure), including ember-resistant vents, Class A roofing, ignition-resistant exterior siding, dual-pane tempered glass windows, and enclosed eaves.
Sellers of homes in VHFHSZs must complete the AB 38 Wildfire Disclosure (effective for sales after July 1, 2021) identifying defensible space compliance and the home's Chapter 7A retrofit status. Insurance carriers increasingly use CAL FIRE FHSZ maps in underwriting; Corona property owners in VHFHSZs may face non-renewal and rely on the California FAIR Plan, with some relief under the 2024 California Department of Insurance Sustainable Insurance Strategy.
