The Raber House project began in 2009 with a Phase 1 and 2 environmental site assessment, which identified metals and petroleum related compounds in soil and groundwater in the area at concentrations in excess of Illinois EPA remediation objectives. Additional investigation was conducted as the city acquired additional adjacent properties, including a former school site. The results of the final subsurface investigation identified the widespread presence of contaminants which interfered with the city’s preferred use of the site for urban agriculture. We oversaw a plan which included importing over 1,500 cubic yards of clean clay to act as barrier under the agricultural growing media, including screening and testing soils located on other site and properties to determine if they were fit for beneficial reuse at the site. We were also responsible for the delivery of civil and environmental services related to the site design and grading plan, stormwater management, and oversight of clean soil importing at the site.
