Tree Protection - What & Why

What's Happening Now?

SDCI administers and enforces the City's tree protection regulations, Seattle Municipal Code Chapter 25.11 Tree Protection, that apply to private property. The purpose of the code is to provide protections for certain trees.

SDCI is part of the City's team that is updating the Urban Forest Management Plan (UFMP). For information on this process please visit the UFMP web page. In September of 2019, the Mayor and City Council adopted a resolution (Resolution 31902) asking SDCI to explore strategies to strengthen tree protections. We are preparing to respond to the Council's direction. Sign up on our listserv if you'd like to receive updates on our progress.
