Redmond follows the King County Noxious Weed List under RCW 17.10 which requires control of Class A and designated Class B noxious weeds such as tansy ragwort, giant hogweed, and knotweed.
Redmond property owners are subject to the Washington State Noxious Weed Control Act (RCW 17.10) and the King County Noxious Weed List adopted annually by the King County Noxious Weed Control Board. Property owners must control Class A weeds (prevent all seed production and eradicate), designated Class B weeds (prevent seed production and reduce populations), and Class C weeds as listed. Common weeds targeted in Redmond include tansy ragwort, poison hemlock, giant hogweed, knotweed (especially along the Sammamish River and Bear Creek corridors where it displaces salmon habitat), and garlic mustard. The King County Noxious Weed Program offers free site visits, identification, and herbicide vouchers. Purely aesthetic weeds like dandelions and clover are not regulated. Failure to control listed noxious weeds can lead to county enforcement and mandatory abatement at the owners expense.
