SouthEast Effective Development (SEED)/Chubby and Tubby

SouthEast Effective Development (SEED) has purchased this former gas station and Chubby and Tubby store in the Rainier Valley of South Seattle. SEED plans to redevelop the site into a mixed-use, residential and commercial building that will include affordable housing. In 2008, King County conducted a Phase II environmental site assessment on the site that found petroleum contamination above Washington State Department of Ecology cleanup standards. SEED will conduct the cleanup and construct the new building during 2008/2009.

City of Bothell/Raincheck Dry Cleaners

This former dry cleaner is located in Bothell, Washington on SR 527. The City of Bothell has targeted this property for possible purchase and redevelopment as part of their "Downtown Plan" which is designed to revitalize the historic core of the city. In 2006, at the city's request, the Brownfields Program conducted an in-depth Phase I environmental site assessment which analyzed prior reports and confirmed contamination of dry cleaning solvents above Washington State Department of Ecology cleanup standards. If the city purchases the property, it will use the information provided in the assessment to address the contamination.

Vashon Island/Ellisport Creek

Starting in the 1920s, a saw mill, millpond and greenhouse were in use on this site located at the head of Tramp Harbor on Vashon Island. The mill and greenhouses were demolished in the 1940s, but the site continued to be used through the 1950s to store and transfer oil for use at other greenhouses on the island. The 8.66-acre site includes tide land and wetlands bisected by Ellisport Creek. The historic uses resulted in the site being contaminated with heavy "Bunker C" oil and other hydrocarbons above Washington State Department of Ecology cleanup standards. Between 2005 and 2007, the Brownfields Program conducted three rounds of Phase II sampling on the site, including a Terrestrial Ecological Evaluation (TEE) (PDF, 4 MB) to determine site-specific cleanup levels. A poster entitled "Using Bioassays to Provide a More Cost Effective Cleanup" (PDF, 5 MB) explains how the TEE was developed. Vashon Island residents, community groups and King County agencies want to see the site cleaned up and set aside for open space and are working to identify a potential property owner and funds for cleanup.

Harborview Medical Center/Former Dry Cleaners

In 2004, King County received a $200,000 cleanup grant from the U.S. Environmental Protection Agency for the Harborview Medical Center (HMC) expansion project. HMC is owned by King County and managed by the University of Washington (UW). King County purchased a contaminated former dry cleaner property as part of the expansion. HMC performed the cleanup in 2005, removing over 13,000 tons of soil contaminated with dry cleaning solvent above State of Washington Department of Ecology cleanup standards. HMC is developing a new, 14-story medical office tower on the site.

The 9th and Jefferson medical office building will house a number of Harborview departments, the King County Medical Examiner's Office, the Neuroscience Institute, the UW's Department of Global Health and additional county agencies. Construction is underway and the new building is scheduled to be complete in January 2009.
