Trees on private property that grow into public spaces, as well as trees planted in the right-of-way (usually the area between the sidewalk and the curb), need you to keep them clear for: 

It is also the adjacent property owner's responsibility to repair any sidewalk damage caused by street trees. If you want or need to hire an arborist for tree maintenance, check out the Local Tree Care Providers page!

Remember that a free Street Tree Pruning Permit from Urban Forestry is required before any tree pruning in the planting strip or right-of-way.

For more information on Urban Forestry tree permits, visit https://www.portlandoregon.gov/trees, email trees@portlandoregon.gov, or call (503) 823-TREE (8733).
