Full Breakdown
BC 5.05.090 defines noxious vegetation to include weeds or grass taller than 12 inches (unless it is an agricultural crop), plus poison oak, poison ivy, and blackberry bushes reaching into a public thoroughfare or across a property line. Subsection C bars any owner or person in charge of property -- including a vacant or unimproved lot in the City of Beaverton, Washington County -- from allowing noxious vegetation on the property or in the adjoining right-of-way. The City can post an abatement notice under BC 5.05.200; if the owner doesn't clear it within ten days, Beaverton may mow or clear the lot itself and place a lien on the property for the cost.
Violations & Fines
Noxious vegetation is an abatable public nuisance under BC 5.05.200-5.05.230; violation is a Class 1 Civil Infraction under BC 5.05.255, and abatement costs become a lien on the property under BC 5.05.215.
