The project supports the planting of trees in the Sumner, Cully, Parkrose, Argay, and Wilks neighborhoods as well as within the Columbia Slough watershed. The specific plangent sites were developed through consultation with community. Urban tree planting provides significant human health and environmental benefits, including carbon sequestration, enhanced air quality (trees can hold small particles on their surfaces and reduce ground level ozone, shade and reduced urban heat island effect, habitat creation, and stormwater management.
