Full Breakdown
63 of the Vista Municipal Code adopts the Fire Hazard Severity Zone system that the California Office of the State Fire Marshal uses to classify wildfire risk statewide. 010 designates land within Vista as medium, high, or very high fire hazard severity zone based on the map titled 'City of Vista Fire Hazard Severity Zones,' dated March 24, 2025, which the City Council adopted by reference through Ordinance No. 2025-03 on June 10, 2025. Subsection B locks in Buena Vista Creek, Buena Creek, and Agua Hedionda Creek as high fire hazard severity zones under Government Code Section 51179, independent of what the map shows for those corridors.
020 resolves split designations: if a single parcel straddles more than one hazard tier, moderate, high, or very high, the entire parcel is treated as falling within the highest tier present anywhere on it, so a lot that is mostly moderate but touches a very-high strip is regulated as very-high in full. 62, including the 10-foot bare-soil clearance around liquid propane tanks and the tiered 10/20/30-foot canopy drip-line spacing on flat, moderately sloped, and steeply sloped lots. 120, punishable by up to a $1,000 fine or six months in jail, or both.
