Have the following information available:
The sidewalk must be lifted and the tree roots exposed before you request an Urban Forestry root pruning permit. Request a sidewalk permit from the Bureau of Transportation by emailing PBOTSidewalkPermits@portlandoregon.gov or calling 503-823-7002.
Once a root pruning permit application is submitted, an Urban Forestry Tree Inspector will visit the site within two full business days and mark the roots that can be cut with orange spray paint. The Tree Inspector will attach the root pruning permit to a street barricade at the site.
A Tree Inspector will only issue a root pruning permit during sidewalk repairs, in order to reduce future damage to the repaired sidewalk. The Tree Inspector may allow tree roots to be cut only if it will not significantly impact the health and structural stability of the tree.
It is recommended that you hire a certified arborist to do the root pruning.
