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 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


50 feet

≥ 2,500 ft2


30 feet

> 1,000 ft2, <2,500 ft2


15 feet

≤ 1,000 ft2

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.

Portland Plant List Nuisance Trees

The trees on this list are NOT eligible for Treebate because of the threat they pose to human health, native plant and animal communities, and public and private property. See the Portland Plant List for more detail.
