Background
Liberty Park is located in Sterling Heights, Michigan, 23 miles north of downtown Detroit. This region, known colloquially as “Automotive Alley,” is home to General Motors, Ford, and Daimler/Chrysler. The area has experienced a growing demand for high-end office and industrial warehouse space. In the last five years in particular, the region has experienced vacancy rates for manufacturing spaces as low as 1.5%.
Liberty Park is a landfill-based, brownfield site. Throughout the 1940’s and 1950’s, a nearby creek was filled with incinerator waste which led to contamination at the site’s low-lying areas. Liberty Park was first redeveloped into a recreation facility in the 1980’s and operated until 2017.
This site posed multiple remediation challenges with a variety of known contaminants including arsenic, lead, and methane. In addition, the site was historically filled in an uncontrolled manner which left the soils with load-bearing capacity issues. To build on the site would require a unique foundation along with a vapor intrusion mitigation solution.
