Eligibility & Treebate Program Details
The Treebate Program provides a one-time credit on your City of Portland sewer/stormwater/water utility bill for planting a tree in your residential yard. Larger trees receive larger credits because they will intercept a greater amount of rain when they are fully grown.
Treebate is an annual program, running from September 1 to April 30, which coincides with the best time to plant a tree in Portland. Trees must be purchased, planted, and applications submitted during this window. Only applications for trees planted during the current planting season are eligible.
Treebate Eligibility Checklist
Please look over the list below before submitting your application to the Treebate Program.
- I am a City of Portland sewer/stormwater/water utility customer for the property where the tree was planted.
- My tree is planted in the yard of a single home or duplex.
- I either own this property or received permission from the owner prior to planting.
- I was not required to plant my tree by City code or a City-issued permit.
- My tree is not identified as a nuisance tree in the Portland Plant List.
- My tree was purchased, planted, and application submitted between September 1, 2020 and April 30, 2021.

What is a Tree?
“Trees” are defined as woody plants that have many secondary branches supported clear of the ground on a single main stem or trunk with clear apical dominance [Huxley, A., ed. (1992). New RHS Dictionary of Gardening. Macmillan ISBN 0-333- 47494-5]. Trees do not include woody plants such as shrubs, arborescent shrubs, specimens bred or pruned to maintain an artificially reduced canopy such as topiary, espaliered or pollarded specimens, small weeping varieties, or plants used to create hedges or other thick, closely-planted buffers or borders on private property.
Treebate Credit Amount
Treebate credits 50% of the purchase price of a tree up to $10 for edible fruit trees, $20 for small trees, $30 for medium trees, and $50 for large trees. Treebate will post as an “adjustment” to your City of Portland sewer/stormwater/water utility bill.
City staff determine the credit amount based on the mature tree size as shown in the following table:
|
Mature Size |
Minimum Mature Height |
Mature Height x Width |
|
Large |
50 feet |
≥ 2,500 ft2 |
|
Medium |
30 feet |
> 1,000 ft2, <2,500 ft2 |
|
Small |
15 feet |
≤ 1,000 ft2 |
The examples below are provided to help you determine if a tree is eligible and what the size of the credit would be. This is not the entire list of potentially eligible trees! Hundreds of trees qualify for Treebate. If you have questions about the tree you would like to plant, just ask treebate@portlandoregon.gov.
