Brownfield Site in St. Louis is Transformed Using MonoShield

Case study highlights:

• Green Street Real Estate Ventures (Green Street), a leading commercial real estate development company based in St. Louis, partnered with environmental consultant ATON Environmental to assess and mitigate the environmental concerns.
• MonoShield® was applied at a former St. Louis manufacturing site to effectively mitigate contaminant vapor intrusion.
• The new River City Business Park is poised to bring jobs, innovation, and sustained economic growth to the community.

In 2009, the Green Street-led development team entered the site into Missouri’s Brownfield Development Program, a move that provided economic incentives to offset some of the site’s significant restoration costs, which included remediating impacted soil and groundwater and raising the building grounds above the river flood plain. Upon entering the program, site remediation commenced to address the contamination. Over time, the site remediation requirements were met, earning a Certificate of Completion issued by the MDNR for all groundwater monitoring. With the Certificate in hand, the project team moved forward with the development. The new River City Business Park would include four large buildings covering an area of 585,000 square feet. The modern, environmentally sustainable, and flexible building plan accommodates diverse uses, offering spaces for office work, light industrial manufacturing, tech ingenuity, and warehousing.
