South Seattle’s
Tree Enhancement Project is Bringing Residents Together
By Ed
Nebendahl
Two of the most ethnically diverse neighborhoods of Seattle, Georgetown
and South Park, are in the process of adding a new tree canopy to their
community. Long seen as just an industrial area, the neighborhood residents are
now getting together to plant trees and green the community.
Most area residents love the
trees that grow in our urban environment but until recently have given little
thought to the importance of a having a tree canopy. The ecosystem services provided
by trees are important in reducing air and noise pollution along with improving
air quality. In fact, by absorbing and filtering out nitrogen dioxide (NO2),
sulfur dioxide (SO2), ozone (O3), carbon monoxide (CO), and absorbing minute
particulate matter in their leaves, urban trees perform a vital air cleaning
service that directly affects the well-being of urban dwellers.
But, that’s not
all. Trees sequester carbon. That is, they remove carbon dioxide from the air
and store it in their trunk, branches and leaves. But wait, there’s more. Along
with cleaning the air they decrease the amount of stormwater runoff volume
generated during a rainstorm which helps with storage and diversion to the river
and Puget Sound which saves on property stormwater fees.
Here are some interesting statistics from a recent Audubon Society CITYgreen
study:
- The whole Seattle area has an estimated average of 23% canopy cover
- Georgetown/South-park has a 3.7% canopy cover
- The Delridge district adjacent to Georgetown/South Park boasts the highest at 34.1%
- A recent study of Georgetown showed the existing trees removed 2,456 lbs. of air pollution for a health care savings approximately $5,523
- 9 tons of carbon are sequestered annually from the existing Georgetown trees
- The cost of future stormwater systems with current or future trees in place is $0 as the study revealed with continued improvement of tree canopy cover adequate stormwater capacity is in place.
Progress is being
made and a new tree canopy density will be the crowning achievement
Since 2001 the Duwamish River Cleanup Coalition, along with the EPA, has
been working towards cleaning up and restoring the Duwamish River and adjacent
neighborhoods of Georgetown and South Park. Cari Simson is a big part of the success. As
program manager for the Duwamish River Cleanup Coalition she has been a part of
those successes, but since 2009 has become more involved on a personal level.
She started Urban Systems Design as she puts it, “to have a more hands on role
helping with the cleanup and restoration”. Her only regret is financially not
being able to grow Urban Systems Design fast enough to increase the successes. Already
this year her involvement has helped give the communities 80 native trees and
by the end of March the goal is 150 trees. She connects people to trees to tree
planting.
Cari is currently involved in the Duwamish Tree Canopy Enhancement
program. Free tree giveaways is only the beginning. Making sure that everyone
receiving a tree knows how and where to plant it, and that they keep up on care
to get it through the critical first few years is also an important step. The location of each tree planted is plotted
on an area map to build a tree canopy projection model. Tree giveaways are
bringing these communities together to share in planting and care. Social media
plays a huge role in keeping people informed of the current happenings. A webpage, “ Hey Duwamish,” allows
people to post comments with information about construction problems and
successes so other residents to see these, learn from them and comment on.
The benefits of a healthy tree canopy are more than just a better looking
neighborhood. The denser canopy will bring a diverse ecosystem, creating
habitat for a variety of urban wildlife and birds. The tree enhancement project
is a major undertaking, but will have the benefit of a healthier community.
Having the community take charge of their trees is an aspect of the program
that truly awesome.
