Auburn owners must control state-listed noxious weeds under RCW 17.10 and King County Weed Board rules. Class A must be eradicated, Class B controlled. ACC 8.12 treats overgrown weeds as nuisance.
Washington State noxious weed law RCW 17.10 requires property owners to eradicate Class A noxious weeds (limited distribution, statewide eradication target) and control Class B weeds (abundant regionally) on their land. The King County Noxious Weed Control Board enforces the list within Auburn and publishes an annual update. Common weeds requiring control in the Green River valley include knotweed species, tansy ragwort, poison hemlock, garlic mustard, Scotch broom, English ivy on trees, and purple loosestrife in wetlands. Auburn City Code Chapter 8.12 further treats uncontrolled weeds over 12 inches or that harbor vermin as a nuisance subject to abatement. Owners receive a Notice of Violation from the Weed Board with a compliance deadline (usually 14 to 30 days depending on species). Failure to comply allows the Weed Board or the city to contract removal and place a lien. Herbicide use near the Green River, Mill Creek, and other critical areas must comply with Ecology aquatic use rules under WAC 173-201A. Pierce County Noxious Weed Program covers the small portion of Auburn south of the King-Pierce line.
