TERMINAL 117
Habitat Restoration & Public Shoreline Access
Terminal 117, formerly known as the Malarkey Asphalt Plant, is owned by the Port of Seattle and
located on the west side of the Duwamish River adjacent to the Boeing Company, the South Park
Marina, and several South Park residences.
Designated by the U.S. Environmental Protection Agency (EPA) as an Early Action Area as part of the
Lower Duwamish Waterway Superfund site, Terminal 117 was cleaned up as a joint project of the Port
of Seattle and the City of Seattle with oversight by the EPA. The uplands cleanup included removal of
pavement, derelict structures and 60,000 tons of soil and sediment. The City of Seattle began the next
phase of environmental cleanup in 2015, including stormwater and street right-of-way improvements
in upland areas adjacent to Terminal 117.

RESTORING A CONTAMINATED SITE FOR THE COMMUNITY AND HABITAT
Artist conception, nal design may change.
Following completion of Terminal 117 cleanup and the
adjacent City of Seattle streets and stormwater work,
the Port plans to restore the formerly contaminated
industrial site as a location combining environmental
health, accessible and safe open space, and sh and
wildlife habitat for South Park citizens to include in
community life.
Present plans, shaped by community ideas and
comments, include public open space, sh and wildlife
habitat, walkways, gathering spaces, viewpoints,
interpretive information, access to the water and
habitat, and public art. The project will provide critical
environmental restoration in the Duwamish Waterway
and contribute a substantial public use and open
space community asset at a formerly inaccessible and
environmentally hazardous location.
