Full Breakdown
3, Vegetation, is one of them: weeds, grass, vines or other growth capable of being ignited and endangering property must be cut down and removed by the owner or occupant of the premises. 057D, and under the city's own vegetation management guidelines. The same amendment package adds Fire Code Section 324, requiring any new building in or next to land with hazardous combustible vegetation to comply with those vegetation management guidelines at the time plans are submitted, and Section 325 lets the fire code official clear flammable vegetation within ten feet of either side of a roadway, measured from the paved edge, with an exception for single ornamental trees, shrubs or ground cover that will not readily carry fire.
Section 326 lets the fire code official suspend the clearance requirements or substitute reasonable alternatives where difficult terrain, erosion risk, protected or rare plant species, heritage tree stands, or other unusual circumstances make strict clearance impractical. Chapter 2's added definitions matter here too: a 'hazardous fire area' is any area identified in the state WUI Code or any other area the fire code official determines is fire-hazardous because of nearby combustible vegetation.
Violations & Fines
Fire Code Section 113.4, as amended by Section 16.08.059, makes violating any fire code provision, including the vegetation-clearance duty, punishable as a misdemeanor, an infraction, or both, with each day a violation continues after notice a separate offense; added Section 113.4.2 makes it specifically an infraction to let a fire or life-safety hazard exist on premises under one's control, while added Section 113.4.3 elevates the violation to a misdemeanor if the owner fails to take immediate action after the fire code official orders the hazard abated.
