Summary
San Diego has extensive Very High Fire Hazard Severity Zones (VHFHSZ) due to its canyon-rim topography and Santa Ana wind exposure. SDMC §142.0412 establishes a comprehensive brush management program with Zone 1 (0-35 ft from structures) requiring fire-resistant, maintained plantings and Zone 2 (35-100 ft) requiring 50% vegetation reduction. The Fire-Rescue Department conducts door-to-door brush assessments for properties along canyon rims in VHFHSZs.
California's seasonally dry Mediterranean climate lends itself to wildfires, and in an effort to better prepare, CAL FIRE is required to classify the severity of fire hazard in areas of California. The History of Fire Hazard Severity Zone Maps Fire Hazard Severity Zone maps arose from major destructive fires, prompting the recognition of these areas and strategies to reduce wildfire risks. Legislative response led to mandated mapping across California under the California Public Resources Code 4201-4204, encompassing all State Responsibility Areas (SRA). What are Fire Hazard Severity Zones? The State Fire Marshal is mandated to classify lands within State Responsibility Areas into Fire Hazard Severity Zones (FHSZ).
Full Breakdown
Multiple San Diego neighborhoods are mapped as Very High Fire Hazard Severity Zones, particularly in the eastern portions of the city including Scripps Ranch, Tierrasanta, San Carlos, Rancho Bernardo, and Black Mountain Ranch. The 2003 Cedar Fire burned directly into Scripps Ranch, destroying over 300 homes in the neighborhood alone. The 2007 Witch Creek Fire caused the largest evacuation in California history, displacing hundreds of thousands across San Diego County. New construction in VHFHSZ requires Chapter 7A fire-resistant building materials. San Diego Fire-Rescue conducts annual defensible space inspections. Santa Ana wind events create extreme fire weather conditions.
Violations & Fines
VHFHSZ building code violations: stop-work order and mandatory correction. Brush clearance failures: abatement at owner expense. PRC §4291 fines up to $500/day.
