Columbia Slough Street Tree Planting Success


This spring, the Environmental Services Tree Program completed its first street tree planting project along the Columbia Corridor. The project planted 163 trees in the public right-of-way, all within the Columbia Slough watershed. The work contributes to several Environmental Services goals:

  • Intercepting rain and reducing stormwater runoff;
  • Increasing natural area connectivity and wildlife habitat;
  • Improving air quality; and
  • Delivering equitable service to a diversity of neighborhoods and demographics.

If our previous planting projects are any indication, we expect future plantings in the slough watershed to draw more participants because of the high visibility of this planting.

The Columbia Corridor is primarily zoned for commercial and industrial use, so Environmental Services worked with several large business properties on this planting. The result was an unusually high number of trees planted at some properties compared to past plantings in residential neighborhoods. We planted 55 trees at Portland Meadows alone, the most we’ve ever planted on a single property.

We couldn’t have done this without our partners: Corky Collier of the Columbia Corridor Association, and the Environmental Services Columbia Slough Watershed Group.

I live in the Columbia Slough watershed and this project is great! I hope to see more projects like this in the coming years. Maybe even focusing on removing impervious pavement and planting trees?

Great job people!
I just hope that when those trees reach their mature height they're not trimmed to death because of the electrical lines overhead (see last photo).

It is always great to have additional trees. Why is it so small though. I think there are bigger tree which could be planted there. Those small trees would take a time to grow into useful one.

Hi Karen-

It's best to plant trees when they're young because it minimizes transplant shock and it's much more cost-effective to plant trees when they're small. So, better for tree health and saves money. It's also very challenging to find trees available in larger sizes. Planting smaller tree stock gives us a lot more options.

Regarding future tree size, we always plant trees that will maximize the space available as they grow. Smaller spaces get smaller trees and bigger spaces get bigger trees.

Again, thanks for the comment.
