Before You Plant
Before planting a tree on a City street (right-of-way), you need to obtain a planting permit. The permit is free and includes an on-site inspection. Before purchasing your tree, call Urban Forestry at 503-823-TREE (8733) to request your planting permit and schedule a free on-site inspection. An Urban Forestry Tree Inspector will make sure the tree you choose is the right tree for the location and will answer any questions you may have. This will ensure that the tree provides the maximum benefit and requires minimal maintenance in the future.
The best street tree is one that fits well in the available space. To help property owners choose the right tree, the City maintains lists of approved street trees based on the width of the planting strip and the presence/absence of overhead high voltage power lines. Generally only primary lines (the power lines usually located above transformers) affect tree selection because trees must not come into contact with these high voltage carriers.
