If the weed is on the list of state regulated noxious weeds for King County, we will visit the site and follow up with the property owner or agency responsible for the area. We will help make sure the weeds are controlled. Even for weeds for which control is not required, is it still helpful for us to know where they are. It helps us learn more about where it is having an impact in King County. To learn more about the Washington State Noxious Weed Law, see our web page on Lists and Laws.
Thank you for helping us locate noxious weeds.
