The South Sound’s first industrial rain garden will become a reality next week at the Totem Ocean Trailer Express terminal at the Port of Tacoma.
More than 100 employees and volunteers are expected to plant about 600 native plants at the marine terminal April 19. The rain garden is designed to filter pollutants from water that runs off building rooftops. It is expected to eliminate more than 80 percent of the heavy metals in the stormwater that otherwise would flow into Commencement Bay.
The installation is being done with help from Stewardship Partners, which is working with Washington State University to install 12,000 rain gardens in the Puget Sound region during the next five years.
Totem Ocean Trailer Express is a privately-owned shipping company operating roll-on/roll-off cargo vessels between the ports of Tacoma and Anchorage, Ala.
