  • Adds criteria to consider tree preservations in specified conditional use and design reviews.
  • Improves consistency of rules for trees in environmental zones, and plan districts.
  • Clarifies intent and updates environmental zoning regulations for non-native non-nuisance trees, and trees in the transition area of environmental zones.

The official Title 33, Planning and Zoning (Zoning Code) is the printed copy in the Development Services Center. PDFs available on are not the official text of Title 33, Planning and Zoning. Although every effort is made to ensure that the two texts are identical, errors or differences may remain. It is the user's responsibility to verify the legal accuracy of all provisions.
