Project Description

The Tree Code Audit Project will produce, by the end of 2021:

  • An audit of how trees are regulated in Beaverton to describe what is working well and what is not working well.
  • Research on other communities’ approaches.
  • A description of potential paths Beaverton could take to address problems or otherwise update tree policies, rules and procedures.

This project does not include changes to city policies, rules and procedures. This is an audit to identify issues and opportunities. Any policy changes or updates to regulations would have to be addressed in a future project.


Beaverton’s tree code has not been significantly updated for many years. Some community members have sought changes to the city’s approach to trees because of a variety of concerns about tree preservation and how trees are regulated. Some applicants also seek greater clarity in city rules regarding trees.

City staff, through interactions with customers and while reviewing development applications, also have identified potential issues.

To better understand the current issues and begin exploring different approaches to managing tree resources, the city initiated the Tree Audit Project.

Development Code rules regarding trees can be found at A major section involving trees can be found in Section 60.60.


The process includes an outside audit of how trees are regulated in Beaverton conducted by Cascadia Partners along with their sub-consultant, Teragan & Associates.

The Cascadia Partners team was asked to audit the city’s tree rules, conduct interviews with people who use the Development Code and seek city staff members’ comments. City staff also interviewed four community members who previously had expressed concerns about the code and advocated for a project to improve how the city regulates trees.

When audit information is available, city staff will seek comments and ideas from the Beaverton Committee for Community Involvement, the Planning Commission, the individuals interviewed in the initial stage of the project and the general public.

The project will result in documents that identify tree code problems and possible paths forward to reconsider the city’s approach toward trees. This will be presented to city leaders and provide background information for a potential future project to make changes to city tree policies, rules and procedures.
