Vegetation clearance requirements in urban-wildfire interface or intermix areas identified by Cal Fires Fire and Resource Assessment Program (FRAP) within the jurisdiction of the City of Rialto Local Responsibility Area defined as very high fire hazard severity zone shall comply with the vegetation clearance requirements of this code and the Public Resources Code 4290 and 4291. The Chief or Fire Code Official may give notice to the owner of the property upon which such condition(s) exist to correct such condition(s).

Full Breakdown
The Rialto Fire Department conducts weed abatement twice a year, with the first inspection round starting in April and the second in October, focusing on vacant lots and overgrown parcels. Per the city's weed abatement program, properties violate the standard when weeds or dry grass exceed 4 inches above ground level or when trash, debris, or overgrown vegetation accumulates. Owners must clear flammable vegetation a minimum of 30 feet around structures (up to 100 feet in some cases), trim tree branches 8 feet off the ground, and maintain easements adjoining their parcels.
The city mails owners notice before inspections; if the owner fails to abate, a city contractor performs the work and the city places a lien on the property. 5 requires a 100-foot firebreak around structures in hazardous fire areas.
Violations & Fines
The fire chief or fire code official may issue a notice to correct, levy daily penalties under amended CFC section 113.4 (misdemeanor, up to $1,000 per day), have a contractor abate the property, and recover the cost through a lien on the property (Ord. No. 1706, amended CFC secs. 304.1.3, 304.5.1).
