Trees are the answer to global warming!

When it comes to reducing the impacts of global warming, there is no substitute for responsible behavior. Planting trees can help lessen some of the problems that face us today while providing benefits that enhance our neighborhoods and our lives.

Thanks to the voter-supported Bridging the Gap initiative, SDOT is planting over 800 street trees per year. That can be good news for your neighborhood.

SDOT is interested in finding neighborhoods where we can plant about 100 trees within (about) a 4 to 5-square block area. These trees will be planted, watered through establishment, and maintained by SDOT.

If your neighborhood has curbed planting strips that are a minimum of 5’ wide, you may be eligible to receive these free trees.

Trees re-absorb carbon dioxide out of the air. They can help reduce energy needs, by cooling homes in summer and blocking cold winds in the winter. They capture storm water and filter dust and dirt from the sky. They beautify our neighborhoods, encourage song birds and help increase property values.

Call 684-TREE (8733) if your neighborhood is interested in “growing solutions” by planting trees.





Some neighborhoods that have received trees:


49th Av SW

Rainier Valley

35th Ave NE

Process from A (application) to T (trees)

  • A - Apply – please see the following guidelines to verify that the location you have in mind is suitable
  • Enter information about your site into our on-line form, or suggest a project location by calling 684-TREE (8733)
  • Urban Forestry team goes out and reviews site suggested
  • Urban Forestry compares location with others submitted
  • If your site is selected, a team will mark proposed tree locations in white paint on the curb line and “plant” small white flags where trees will likely be located
  • A door hanger which gives general information about the project, and lists available tree types will be placed on doorknobs of neighborhood houses
  • Neighbors give us feedback
  • Trees will be planted in March/April in the spring and in November/December in the fall.
  • Water bags will be installed on trees late in the spring, and filled once a week throughout the summer (as shown in this picture). We may ask that neighbors add water to the bags once a week, if the weather is exceptionally hot and dry.
  • Water bags will be installed each spring for three years. Urban Forestry crews will be responsible for pruning the trees as needed
  • T - Trees: By year three or four, the trees should be well established and on their way to creating a lovely canopy that will beautify your neighborhood for the years to come! Should any of the trees appear damaged or infected, please call us immediately at: 684-TREE (8733)

Tree planting guidelines:

Does your neighborhood fit the requirements?

  • There must be a minimum of 5’ planting strip from the curb to the sidewalk.
  • There must be a curb, if there is no curb, planting may be possible as long as there is a sidewalk.
  • The area to be planted should preferably accommodate a minimum of 50 trees.

To estimate the number of trees that could be planted in your suggested location:

  • If there are overhead power lines, then small trees will be planted 20’- 25’ apart.
  • If there are no overhead power lines, then medium sized trees will be planted 35’ – 40’ apart
  • If trees are to be planted on both sides of the street, approximately 12 to 20 trees would be planted per block
  • If trees are planted on just one side of the street, approximately 6 to 10 trees would be planted per block.
