Summary
Vacant lot owners in Benton County must control noxious weeds and clear debris. State law (RCW 17.10) makes every owner responsible for eradicating and controlling listed weeds, enforced by the Benton County Noxious Weed Control Board.
Every owner must perform or cause to be performed those acts as may be necessary to: (a) Eradicate all class A noxious weeds; (b) Control and prevent the spread of all class B noxious weeds designated for control in that region within and from the owner's property.
Full Breakdown
An empty parcel is not exempt from maintenance. Under Washington's noxious weed law, RCW 17.10, every landowner, including vacant-lot owners, must control and prevent the spread of state- and county-listed noxious weeds; the Benton County Noxious Weed Control Board enforces this. Arid-country problem weeds here include puncturevine (goathead), knapweed, and kochia rather than the blackberry and Scotch broom common west of the Cascades. Local nuisance codes separately require removing trash and dry vegetation and securing hazards. Dry weeds are a genuine wildfire fuel in this climate. Uncontrolled weeds or dumping can trigger a weed-board notice or a code-compliance abatement billed to the owner.
Violations & Fines
The weed board can order control and, if ignored, perform it and bill the owner. Local code-compliance can abate trash and fire-fuel accumulations on a vacant lot at the owner's expense.
