Treebate Program Details

Every tree planted in Portland contributes to clean rivers and healthy watersheds. So, if you plant an eligible tree on a residential property between September 1 and April 30, Environmental Services will credit your city sewer/stormwater/water utility bill for half the purchase price per tree up to $15 (small), $25 (medium) or $50 (large) depending on mature tree size and stormwater management potential.


How to Get Your Treebate

  1. Purchase a tree between September 1 and April 30*
  2. Plant it in your Portland residential yard. Complete and submit a Treebate form by April 30 (include the tree purchase receipt with the purchase price circled)
  3. Receive a credit on your city water/sewer utility bill

*Generally, most tree species are eligible for a Treebate; see the eligible list for conditions and ineligible list for exclusions.

Protect Your Investment

Late fall through early spring is prime tree planting season. Be sure to plant your tree correctly and give it proper care and maintenance. Newly planted trees require deep weekly watering (~10 gal.) during the dry summer season from June through September.
