Seattle Tree Inventory Map

The street tree map provides info on individual street trees:

  • scientific name and common name
  • inventory identification number
  • diameter
  • street address
  • party responsible for maintenance
  • date the tree was planted or inventoried
  • date that the tree was last checked by clicking on an individual tree.

There are approximately 130,000 trees along Seattle's streets. The map has approximately 40,000 city-maintained trees that are inventoried.

About the map data

  • Data in this map is for general information purposes only, and should not be used for plan review or other “official” purposes.
  • Inventory data for trees maintained by the SDOT was updated in 2007 and 2008 and SDOT has continued to update plantings in the inventory.
  • Since the initial inventory was completed in 1992, over 25,000 street trees have been planted. Funding for these trees has come from SDOT Capital Improvement Projects and “Bridging the Gap” Plantings, City Light’s Urban Tree Replacement Program, the Department of Neighborhoods Tree Fund, private development, and private citizens.
  • Trees that were inventoried in 1990 – 1992 will not display diameter information unless the “Last Verified Date” field is populated with a recent date.
