Urban Forestry

The Urban Forestry program's mission is to administer, maintain, protect, and expand the City's urban landscape in street right-of-ways for Seattle's residents and businesses so that environmental, aesthetic, and safety benefits are maximized. Urban Forestry consists of the City Arborist Office, the Landscape Architect Office and the Outreach and Special Projects Office.

Seattle reLeaf Taking care of our trees is good for our environment, our neighborhoods, and ourselves. Trees clean our air and water, reduce global warming pollution, provide habitat for wildlife, raise property values and offer green relief throughout our city. Seattle’s trees have been in decline and we all have a role to play to “keep the Emerald City green.” The City has increased its investments in tree care and planting, is looking at ways to improve regulations, and is spreading the word about the importance of trees and how to care for them. This web portal is your link to information about trees on the City’s web pages and beyond. April 9th is Arbor Day in Washington – celebrate by planting a tree! Find out more!
