Inside the city, weed control sits in KMC 9.48 with the 12-inch Weed Hazard rule. Layered on top, RCW 17.10 (the Washington State Noxious Weed Law) gives the Benton County Noxious Weed Control Board authority to order eradication of state-listed Class A, B, and C weeds.
KMC 9.48.010(4) treats dead, dried, or unirrigated grasses, weeds, or other vegetation over twelve inches in length as a public nuisance and gives the Code Enforcement Division a 20-day compliance track. RCW 17.10 sets up a parallel state framework: every county must run a noxious weed control board, eradication of all Class A plants is required by law, and selected Class B species are required to be controlled by region. The Benton County Noxious Weed Control Board (509-943-6005) administers Kennewick's portion. Under RCW 17.10.170, if a landowner does not act, the county board can enforce control at the owner's expense — labor, material, and an application cost. The Washington State Noxious Weed Control Board publishes the annual statewide list at nwcb.wa.gov.
Inside the city, 9.48 enforcement starts with a 20-day notice followed by civil or criminal infractions and cost recovery. Failure to control a Class A or designated Class B weed lets the Benton County board file civil infractions and bill the landowner under RCW 17.10.170.
