What rules apply?

Street trees in Portland are regulated through the city's urban forestry program and applicable municipal code and administrative rules. The city's Urban Forestry program publishes planting guidance, approved species lists, and permit processes for work in the public right-of-way. Specific code sections and fee schedules are available from the official city pages cited below.

Always check the city's approved street tree species list before selecting a species.

Design & Planting Standards

Design standards address spacing, soil volume, planting strip width, root barriers, conflict with utilities, and minimum clearances. Many projects require an approved planting plan and coordination with utilities and transportation works.

  • Permit required for work in the public right-of-way, including planting, pruning, and removal.
  • Installation standards for soil volume, root barriers, and grates; exact minimums are not specified on the cited page.
  • Clearance standards for sidewalks, sightlines, and overhead utilities to avoid conflicts.
  • Species selection guided by an approved street tree list to ensure suitability and public safety.
Planting within the public right-of-way typically requires an approved permit.
