Protect Your Home from Wildfire

Updated 2025 Fire Hazard Severity Zones in Local Responsibility Area

The State Fire Marshal's Office has updated the Fire Hazard Severity Zones (FHSZ) in Fullerton's Local Responsibility Area (LRA) for 2025 to better reflect areas with elevated wildfire hazard potential. These updates utilize scientific research, climate data, and fire modeling to identify hazards and improve preparedness. The updated FHSZ were adopted by City Council on May 6, 2025 and incorporated by Ordinance into Fullerton Municipal Code 13.19.

Key Practices for Fire Prevention

• Clear Vegetation: Remove weeds, dead plants, and overgrown vegetation within 100 feet of your home.
• Create a Defensible Space: Maintain a clear space around your property to act as a buffer zone.
• Tree and Shrub Maintenance: Prune tree branches to remove undergrowth and ensure a minimum clearance of six feet from the ground. Trim branches to keep them at least 10 feet away from chimneys.
• Remove Combustible Materials: Clear dead leaves, pine needles, and other debris from rooftops and gutters. Properly dispose of all cut materials.
• Use Fire-Resistant Plants: Whenever possible, replace highly combustible plants with fire-resistant ones. Ensure adequate spacing and reduce plant material to minimize fire risk.
• Brush Clearance: Always have a water source readily available, avoid clearing brush during peak temperatures, use properly maintained equipment, and wear appropriate safety gear.

Self-Inspection Checklist

• Prune tree branches and undergrowth to at least six (6) feet from the ground.
• Remove diseased, dead, or dying trees and branches.
• Clear dead leaves and pine needles from rooftops and gutters.
• Properly dispose of chip (mulch) or bagged materials and spread them to no higher than five (5) inches.
• Ensure address markers are clearly visible on the front of all buildings.
• Store firewood at least fifteen (15) feet away from structures.
• Maintain a three (3) foot clearance of all vegetation and dirt around fire hydrants adjacent to property lines.
