SECO Development

Floyd|Snider has provided services to SECO Development on multiple properties. Floyd|Snider personnel assisted SECO Development with Prospective Purchaser Agreement (PPA) negotiations associated with the 20-acre mixed-use Juanita Village development in Kirkland. Prior to its redevelopment, a dry cleaning facility was located on the site. Environmental property assessments identified a plume of tetrachloroethene (PCE) in groundwater migrating toward Lake Washington. The PPA Consent Decree quantified environmental cleanup costs and capped SECO Development’s environmental liability with regard to the PCE release. This allowed to project to move forward, as it eliminated the threat of future legal action by the Washington State Department of Ecology (Ecology). Following the PPA, Floyd|Snider personnel prepared a Feasibility Study and Cleanup Action Plan which documented the selected remedial actions at the site: soil vapor extraction (SVE) and density-driven convection wells (DDE). Floyd|Snider also assisted SECO Development investigate the merits of a remediation cost cap insurance policy that would limit the risk of cost overruns during the cleanup. 

Floyd|Snider also worked with SECO at the Southport Development property in Renton. Southport is a 17-acre mixed-use development located on the shores of Lake Washington at the former Shuffleton Steam Plant site, a power-generating facility owned and operated by Puget Sound Energy (PSE) since the 1920s. The site was a known hazardous waste site at the time of its sale in 1997 based on the presence of heavy fuel oils, arsenic, lead, and polychlorinated biphenyls (PCBs) in site soils.

Residual heavy oil contamination was discovered at very high concentrations along the foundation of the power plant building. Floyd|Snider developed a plan for in-situ bioremediation of the residual soil contamination. The plan was successfully implemented and Ecology granted an unrestricted No Further Action letter for this cleanup in January 2001.

Other Floyd|Snider activities involved the recognition and responsible handling of hazardous materials left behind at the former steam plant, mainly large volumes of liquid mercury in switches, lead-based paint, and asbestos.

Following remediation of the site and issuance of the No Further Action letter, Floyd|Snider remained involved addressing environmental issues that arose during development construction. Significant soil contamination was identified during installation of the main site sewer line, which was found to be Bunker C-saturated soil. Floyd|Snider designed a remediation plan that utilized the skills of the infrastructure contractor (Coluccio Construction) and also dovetailed into the infrastructure scheduling. Large-scale dewatering wells were used to lower the groundwater table in the area requiring excavation. Dewatering was successful in lowering the water table enough to allow removal of all of the contaminated soil.
