Redevelopment at the Site

The Pacific Sound Resources Superfund site, formerly known as the Wyckoff West Seattle Wood Treating facility, is located on the south shore of Elliott Bay on the Puget Sound in Seattle, Washington. The site encompasses 83 acres, 58 acres of which are marine sediments. The surrounding areas are primarily commercial and industrial. From the turn of the century until 1994, a wood treating facility operating on site released creosote and related hazardous contaminants into the ground and marine environment. Contaminants eventually seeped into the tidal sediments. EPA listed the site on the Superfund program's National Priorities List (NPL) in 1994. Cleanup actions included removing soil, dredging sediment, constructing an upland slurry wall, placing a 25-acre asphalt cap in the upland and a 58-acre cap over marine sediments. The Port of Seattle purchased the upland property in 1994 and included it as part of the Port’s efforts to construct a modern container terminal facility in West Seattle. During this period, the Port implemented several early cleanup actions, under EPA oversight, to stabilize releases from the site and to prepare it for reuse. The Port is currently using the southern portion of the upland property as part of the Port’s container terminal facility. EPA and the Port worked together to redevelop the northern portion into a Port of Seattle waterfront park, known as Jack Block Park. Routine monitoring of the marine sediment cap and groundwater continues.
