5004. "Noxious weed" means any species of plant that is, or is liable to be, troublesome, aggressive, intrusive, detrimental, or destructive to agriculture, silviculture, or important native species, and difficult to control or eradicate, which the director, by regulation, designates to be a noxious weed. In determining whether or not a species shall be designated a noxious weed for the purposes of protecting silviculture or important native plant species, the director shall not make that designation if the designation will be detrimental to agriculture. (Amended by Stats. 1992, Ch. 556, Sec. 1. Effective January 1, 1993.)
Full Breakdown
16 declares overgrown weeds, dry grass, and accumulated combustible vegetation a public nuisance. Annual weed abatement notices typically go out in April-May, requiring property owners to clear lots before peak fire weather (June-November). and California Government Code §39501 authorize the city to abate at the owner's expense and lien the property for non-compliance. In hillside, rural, and wildland-urban interface (WUI) areas, including neighborhoods bordering the Santa Margarita Ecological Reserve, French Valley, and the eastern Vail Lake/De Luz foothills, California Public Resources Code §4291 and the California Fire Code require 100 feet of defensible space around all structures: Zone 0 (0-5 ft, ember-resistant), Zone 1 (5-30 ft, lean/clean/green), and Zone 2 (30-100 ft, reduced fuel).
Riverside County Fire (CAL FIRE under contract) performs WUI inspections. Weeds taller than 18 inches, accumulated tumbleweeds, dead palm fronds, and dry brush within 30 feet of a residence are typical violations. First notice gives 30 days to comply; failure to abate triggers a city-contracted clearance and an administrative fee of several hundred to several thousand dollars depending on lot size.
