Oakley, CA Fire Regulations: Wildfire Zones (2026)

CAL FIRE's Fire Hazard Severity Zone (FHSZ) maps classify areas into Moderate, High, and Very High categories based on fuel, slope, weather, and fire history. The maps distinguish between State Responsibility Areas (SRA) managed by CAL FIRE and Local Responsibility Areas (LRA) enforced by municipal or district fire agencies. Oakley is primarily within a Local Responsibility Area, and most of the city is not classified as a Very High Fire Hazard Severity Zone. However, eastern Contra Costa County has substantial grass-fire exposure, and peripheral parcels adjacent to open space, grasslands, the Delta shoreline, and the Marsh Creek/Dutch Slough corridors may have hazard-zone designations. The East Contra Costa Fire Protection District (ECCFPD) enforces wildfire preparation standards under California Public Resources Code Section 4291, which requires 100 feet of defensible space around structures. Zone 0 (a new 0-5 foot ember-resistant buffer under AB 3074) requires noncombustible ground cover, no woody plants touching the structure, no combustibles under decks, and metal screening on vents. Zone 1 (5-30 feet) requires dead-vegetation removal, limbing trees at least 6 feet from the ground, 10 feet of horizontal canopy separation, and relocation of firewood and propane 30 feet away. Zone 2 (30-100 feet) requires grasses cut to 4 inches, shrub spacing, and removal of dead wood and ladder fuels. ECCFPD performs annual weed-abatement inspections in spring with enforcement by abatement lien. New construction in mapped hazard zones must meet Chapter 7A ignition-resistant building standards (Class A roofing, ember-resistant vents, noncombustible siding, tempered windows). California insurers increasingly require Safer from Wildfires compliance documentation for homeowners policies.
