Care of Trees

By caring for your trees you are making an investment for yourself and future generations, as well as for the community at large. The information below can help you protect your investment for years to come.

Additional Tree Resources:


  • Significant Trees: Trees adopted by the City, with the approval of the property owner, as trees of significance related to a historic event, uniqueness of shape or species, location, age, or functionality. More about significant trees.  
  • Tree Topping: The severe cutting back of limbs or main stem to stubs larger than three inches in diameter within the tree’s crown to such a degree as to remove the normal top and disfigure the tree.  


  • No permit is required to prune a tree on private property, unless it is a designated significant tree.
  • Property owners are responsible for maintenance of street trees located in the public right-of-way next to their properties.
  • If the pruning constitutes tree topping, as defined above, a type I street tree removal permit is required.
  • Street trees are to be pruned in accordance with tree-trimming standards approved by the City.
  • All overhanging branches must be at least 8 feet above the sidewalk and 12 feet above the street.
  • If more than 20% of the tree canopy is removed, or if root-pruning is involved, additional requirements may apply. Contact the Planner on Duty at 503-618-2780 or

Street Trees

Trees in the planter strip located between the sidewalk and the curb, and often trees located within 10 feet of the front property line are street trees. Removal of these trees requires a type I street tree removal permit. Additionally, the trees must be replaced using the Street Tree List.

Tree Removal

Trees in Gresham are regulated differently depending on their location, purpose, size, and significance. More about tree removal.

Trees and Sidewalks

When a street tree lifts the sidewalk in front of your house, the sidewalk must be repaired.

  • Have a tree care professional provide an assessment and estimate for root-pruning or removal of a tree.
  • Contact the City's Public Works Inspector at 503-618-2105 to evaluate sidewalk damage. After the inspection you will need to visit the Permit Center at City Hall to file a right-of-way permit. Contact Permit Services at 503-618-2845 for more information.
  • If a street tree causing sidewalk damage requires removal to accommodate sidewalk repairs, you must contact the Planner on Duty at 503-618-2780 or and submit a type I street tree removal permit
