Troutdale maintains an official Nuisance Plants list (40+ species removable without environmental review) and a Prohibited Plants list (Scot's Broom, English Ivy, Purple Loosestrife, Reed Canarygrass, Himalayan Blackberry) banned from all reviewed landscaping. Persistent infestations are abated under TMC Chapter 8.28.
Troutdale Community Development publishes two formal plant lists. The Nuisance Plants list identifies 40+ species — including Canada thistle, poison hemlock, English holly, English laurel, evergreen blackberry, tansy ragwort, common dandelion, and bamboo — that dominate plant communities or harm humans. These may be removed without environmental or greenway review. The Prohibited Plants list bars five species from any reviewed landscaping citywide: Scot's Broom, English Ivy, Purple Loosestrife, Reed Canarygrass, and Himalayan Blackberry (including all cultivars). Active infestations can be cited as a nuisance under TMC Chapter 8.28; ORS 569 noxious weed law may add to state-listed species.
Installing a prohibited species in a reviewed landscape plan can result in plan denial or removal as a permit condition. Nuisance infestations can trigger TMC 8.28 abatement, with costs assessed as a property lien.
