Short blurb from Sustainable Business Oregon on a new ‘EcoTrack‘ for the light rail expansion in Portland.

“The vegetated trackway, which aims to reduce stormwater runoff, is among the first such efforts in the U.S. It will adorn a station at Southwest Lincoln Street and Third Avenue near the Portland State University campus.

The installation “will provide a colorful carpet of low-growing plants along 200 feet of light rail line,” according to the transit agency. The technique is common in Europe and consists of one-inch thick mats that contain various species of sedum, which are a hardy low-maintenance vegetation.”
