treeNew Development & Trees

SDOT'sLandscape Architect Unit coordinates with SDCI during the Early Design Guidance review for new projects. We identify exceptional trees and begin early discussions with SDCI, developers and the community regarding tree preservation and tree selection for new street trees. Property that is to be developed will have an SDCI notice posted providing information about the project and who to contact with your questions and comments

Trees adjacent to construction sites that are posted with green Protect Tree signs are designated for protection and are routinely inspected by the Seattle Transportation Landscape Architect's Office. To discuss concerns regarding a specific project, at 206-684-TREE (8733).


Tree Removal Approval Process

When trees must be removed for construction of new projects, the City of Seattle require public notification. If you see a notice and want to comment on a project, check tree placards for appropriate contact information. Follow the link to SDCI for information on tree protection regulations on private property during development. SDCI provides incentives for developers to work with community members through Design Review meetings where the public can speak to the importance of tree preservation landscape elements, and building design issues.
