Washington County Tree Code
Ideas and Background Information

Establishing a "tree code", or set of tree protection ordinances, is one tool

for keeping our urban forest healthy and well-managed.  

Washington County is one of the last places in the Portland Metro area that does not have regulations to protect trees in its urban unincorporated areas, despite a clear need and years community requests for protections. 

Here are some resources we can use as we work to establish a "tree board" or committee. The tree board's first purpose would be to advise the county on the best way to write tree protections into our ordinances.

Joint CPO Research Paper 2007

This extensive research paper is still very applicable today - though it was developed so long ago!  Washington County Commissioners have not acted upon the annual requests of the Oregon-recognized Community representative group (CPO/CCI) for all these years.  These early efforts were not necessarily focused on Urban Unincorporated Washington County - and this is why TreekeepersWC has narrowed the focus to help move this issue along.

Wilsonville Online Interactive Tree Inventory
and Urban Tree Management Plan

"The City of Wilsonville has a deep and storied commitment to maintaining and promoting consistent investment in the community's urban forestry resources. Wilsonville has been awarded the Tree City USA recognition for 19 consecutive years, an affirmation of the work the City invests into its urban canopy. 

A large part of the work of maintaining and caring for Wilsonville's tree population includes keeping an ongoing inventory of its street trees. 2021 was an especially important year for the city to update its street tree inventory because of the winter storm that shattered hundreds of tree limbs and cracked many tree trunks."
