"As completion of the Portland-Milwaukie Light Rail line hits the 70 percent mark, TriMet officials want future riders to take note of what they’re calling an “eco-track” at one of the project’s new stations.
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.
Stacy and Witbeck Inc. installed the track last month.
The 7.3-mile project is set to open Sept. 12, 2015. It will essentially link downtown Portland with North Clackamas County via light rail."1
