Boeing's efforts to cleanup and restore the wetlands and wildlife habitat along the Lower Duwamish Waterway at Plant 2 are all part of the company's larger commitment to conduct environmental work that is vital to the ecosystem, the Puget Sound and to the community.
Boeing will create or restore nearly five acres of intertidal wetlands and wildlife habitat and more than 3,000 lineal feet of shoreline.
Migrating salmon-while not directly threatened by contaminated sediments-are dependent on the waterway as it remains an important habitat for spawning Chinook, Coho, Chum, Steelhead, Pink and Sockeye salmon. As a result, the creation and protection of salmon habitat is a priority for the natural resource restoration efforts along the Lower Duwamish Waterway.
Two native Tribes-the Muckleshoot and Suquamish-fish in the Lower Duwamish. The neighboring corridor is also home to several parks, open spaces and residential neighborhoods.
In September, 2011, the historic Plant 2 was totally demolished.
When it was originally built in the late 1930s to support the U.S. war effort, portions of Plant 2 were constructed on pilings over the water. Boeing is removing more than 53,000 square feet of over-water structures.
More than 85 percent of the building's materials including steel and wood beams, copper wiring, concrete and other miscellaneous metals are being recycled or reused.
A state-of-the-art treatment system has been built to clean stormwater to residential standards before being released into the Duwamish.
Starting in 2012, Boeing will begin removing more than 200,000 cubic yards of sediment and replace it with clean material in the riverbed.
Boeing is cleaning up its own properties and past industrial practices. Equally important, the company is partnering with businesses, Tribes, government agencies and the local community to give the U.S. Environmental Protection Agency and the Department of Ecology the tools to implement protective, timely and cost effective cleanup solutions for the Lower Duwamish Waterway.
