Timeline and process

For current information on processing times, please refer to Alert articles or contact Urban Forestry via the Tree Hotline 503-823-TREE(8733) or email at  Incomplete applications will delay the process. 

After the completed application has been received, an Urban Forestry Tree Inspector will visit the tree planting site to identify site conditions and mark the curb with paint for the appropriate placement of trees. After the site visit, the Tree Inspector will contact the applicant with an approved list of tree species for planting, based upon the size of the planting strip and presence of overhead high-voltage power lines. The applicant must then communicate the species selection from the list to the Tree Inspector, and the Tree Inspector will then send the applicant the planting permit.

Planting permits are valid for 30 days.
