ProLogis - Taylor Way Site

Floyd|Snider was retained by ProLogis to fulfill the requirements of an Agreed Order with the Washington State Department of Ecology (Ecology) to perform a Remedial Investigation/Feasibility Study (RI/FS) of a 10-acre undeveloped land located on the Blair Peninsula in the Tacoma Tideflats area. The ProLogis Taylor Way Property was originally slated for warehouse redevelopment, but development was complicated by adjacent property contamination that extended onto the ProLogis property. The ProLogis site was originally part of a larger site developed in the late 1920s to early 1930s with a wood manufacturing plant; the southern one-third of the site remaining a tidal marsh. Activities involved with the historical land use of the site and adjacent property resulted in the presence of volatile organic compounds, semivolatile organic compounds, total petroleum hydrocarbons, and metals. 

Floyd|Snider worked with Ecology and produced RI and FS Reports defining cleanup actions required at the site to support redevelopment. Remedial investigation work included soil test pit explorations, installation of groundwater monitoring wells and piezometers, and quarterly monitoring of groundwater at the site.

Ecology concurred with recommendations in the FS to cap the site as part of a future redevelopment which will prevent stormwater infiltration into metals-impacted soil. The Port of Tacoma later purchased the site from ProLogis following Ecology approval of the RI/FS.
