Tigard's weed rules are part of the nuisance code in TMC Chapter 6.02, with 'noxious vegetation' defined in TMC 6.01.020.M.8. The definition includes English ivy, giant hogweed, purple loosestrife, Japanese knotweed, Himalayan blackberry, and weeds over 10 inches going to seed.
TMC 6.01.020.M.8 defines 'noxious vegetation' to include weeds over 10 inches going to seed, vegetation that obstructs view of the right-of-way or makes it hazardous, and specific invasive plants — English ivy, giant hogweed, purple loosestrife, Japanese knotweed, and Himalayan blackberry. TMC Chapter 6.02 makes it unlawful to plant or allow these on a property, and requires the responsible party to remove or destroy them. The chapter also requires affirmative maintenance — cutting weeds and brush as often as needed to keep them from maturing or going to seed. Enforcement runs through Tigard Code Compliance.
Responsible parties who plant or allow listed noxious vegetation, or let weeds over 10 inches go to seed, face nuisance abatement and civil-infraction citations under TMC 6.02 and 1.16. Failure leads to city abatement at the owner's cost.
