Bellevue property owners must control noxious weeds under RCW 17.10 and King County Noxious Weed Board rules; general weed maintenance enforced via nuisance code.
Weed control on Bellevue properties is governed primarily by state and county rules rather than specific city ordinances. Washington State noxious weed law RCW 17.10 and the King County Noxious Weed Control Board designate certain invasive species as Class A (eradication required), Class B (control required), or Class C (recommended control) weeds. Common targets in Bellevue include tansy ragwort, purple loosestrife, knotweed, Himalayan blackberry in sensitive areas, English ivy in natural areas, and garlic mustard. Property owners receiving noxious weed violation notices from King County must control infestations within 14 days or face enforcement. General weed and unkempt vegetation maintenance is handled through Bellevue City Code Chapter 9.06 public nuisance provisions on a complaint-driven basis. Properties adjacent to parks, natural areas, or critical areas face heightened scrutiny to prevent invasive spread. Herbicide use near wetlands, streams, or shorelines is restricted under Critical Areas Ordinance and state water quality regulations.
