Site Description
Lockheed Yard 2 (Yard 2) encompasses approximately 40 acres, with approximately 24.5-acres of uplands and 15.5 acres of submerged sediments. It is located on the eastern side of Terminal 5 at 2330 SW Florida St. at what is now Jack Block Park.
Site History
Yard 2 was part of Elliott Bay’s intertidal zone until it was filled in the 1930s. Puget Sound Bridge & Dredging Company began operations at this site in 1943 to build ships for the U.S. Navy. Lockheed Shipbuilding Company then operated the site from until1959 until 1986. It was purchased by the Port in 1992.
Contamination Issue
Historical industrial practices including ship building, dry dock ship repairs, vessel sandblasting, and painting resulted in contamination of soil and sediment. Contaminants of concern in the sediment portion included polyaromatic hydrocarbons, polychlorinated biphenyls, and metals such as arsenic, copper, lead, and mercury.
What is the Port’s Role in this Cleanup?
Lockheed Martin completed the cleanup. As the current owner of the Site and pursuant to an agreement with Lockheed Martin, the Port now maintains the sediment cap and overall site.
Status
The cleanup began in 2018 and was completed in 2020. Approximately 167,000 cubic yards of contaminated material were dredged and disposed of offsite, and creosote-treated pilings were removed. A sediment cap of clean material was placed over the dredged area.
Yard 2 is now in long-term monitoring with regular five-year reviews.
