ENB-4.23 - Treebate Program


Binding City Policy


Link to Exhibit A  (PDF Document, 101 kb) 


Section 1. The Council finds:

1.  The Bureau of Environmental Services (BES) needs to manage stormwater to protect and promote human and watershed health. The ecosystem benefits provided by trees are well documented and broadly accepted. Increased urban canopy reduces stormwater runoff that causes street and basement flooding, erosion, combined sewer overflows, and sewer surcharging. Urban trees provide local climate benefits by absorbing solar radiation, creating cooler micro-climates outside and in adjacent structures. These benefits have been incorporated into established City plans, policies and goals regarding watershed management, stormwater management, control of combined sewer overflows, climate change, and comprehensive planning.

2.  Environmental Services’ Treebate Program, established by Council Ordinance (#183307) in November 2009, provides financial incentives for property owners ranging from $15 to $50 per yard tree planted. BES offers the program to Portland stormwater ratepayers in the form of a one-time discount on the recipient’s City utility bill.

3.  The average annual Treebate Program cost is $8,500 per year in uncollected sewer and stormwater charges. Funds for administrative and materials costs are available in the Sewer System Operating Fund, FY19 Budget, Bureau of Environmental Services, ESWS000015, 9ESWS15WR002.


NOW, THEREFORE, the Council directs:

a.  Environmental Services’ Treebate Program is authorized to issue utility bill credits for eligible trees. The authorized revenue adjustments for Treebates shall be accounted for in a manner that limits any rate-making impacts to the calculation of stormwater management user service charges.

b.  The Director of the Bureau of Environmental Services is authorized to implement Environmental Services’ Treebate Program consistent with the administrative rules set forth in Exhibit A of this Ordinance.

c.  This Ordinance and the attached administrative rules are binding City policies. The Director of the Bureau of Environmental Services or his designee is authorized to make any future modifications to these administrative rules, and implement additional administrative rules, as deemed necessary per the procedures in PCC 3.13.040.
