Title 11 Trees Code Amendments - Seeking Public Input

The City of Portland is seeking public input in response to recommendations by the Planning and Sustainability Commission and the Urban Forestry Commission to further strengthen tree preservation in City Code Title 11 Trees. In January 2020, City Council directed PP&R Urban Forestry, the Bureau of Development Services, and the Bureau of Planning and Sustainability to propose amendments addressing:

  • Removing exemptions to tree preservation (and tree planting or “density requirements”) in industrial and commercial zones; and
  • Reducing the size threshold when “inch for inch” mitigation kicks in when large trees are removed in private property development situations. Currently, the size threshold is 36" diameter at breast height (DBH) and the proposal is to reduce this threshold to 20” DBH.

The City will be conducting surveys and holding educational meetings to share analysis and research on this topic and inviting the views of community members.
