The Urban Forestry Commission meets on amendments to Title 11

Root protection fencingThe Urban Forestry Commission will hear proposed amendments to Title 11, Trees, regarding tree preservation in development situations on Thursday, January 21, 2016. The hearing will begin at 6:00 p.m., 1900 SW 4th Avenue, Room 2500B.  

Due to recent public concern about large trees being removed in development situations in Portland neighborhoods, amendments to Title 11, Trees, are proposed to strengthen regulations pertaining to tree preservation, especially preservation of large sized trees, in development situations. The proposed amendments aim to:

  1. Revise the mitigation requirement (payment into the Tree Planting and Preservation Fund) to be based on the size of the tree removed. Currently, the same mitigation is required for all trees removed regardless of size.

  2. Add a notification requirement when trees in the largest size category are proposed for removal.

There are currently two specific proposals being considered: Proposal A is dated November 3, 2015 and Proposal B is dated December 11, 2015. Comparison Table showing current code, Proposal A and Proposal B.

Note: The proposals are subject to change prior to the Urban Forestry Commission Hearing. Updated proposals will be posted if/when they become available.

Testimony on the proposal can be made in person at the hearing or submitted in writing. To submit written testimony, mail comments to the Urban Forestry Commission, Portland Parks and Recreation, at 1900 SW Fourth Avenue, Suite 5000, Portland, Oregon 97201; or email comments to Written testimony must be received by the time of the hearing and must include your name and address.
