Roxana Marsh Native Landscape Contractors, LLC. (NLC) was the restoration/remediation sub-contractor within a team of contractors for the Grand Calumet River Cleanup overseen by the US EPA, US Fish and Wildlife Service, and the Indiana Departments of Environmental Management and Natural Resources Division. Roxana Marsh was Phase II of the project located along the West Branch of the Grand Calumet in Northwest Indiana with the entire $31.1 million project being funded under the Great Lakes Legacy Act signed by the US Government. Both sites are listed by the US EPA as Areas of Concern (AOC), located in one of the most industrialized areas in the country as well as home to some of the most diverse native plant and animal communities in the Great Lake Basin. The prime contractor is responsible for dredging 1 mile of the river to replace 82,000 cubic yards or polluted sediment containing PCBs, PAHs, heavy metals, and pesticides followed with the placement of a clay/sand cap over the dredged area. Other contractors are involved with the dewatering and disposal of the contaminated sediment, water and air quality monitoring, and terrestrial excavation within Roxana Marsh.


Prior to work beginning, ecology + vision, llc. developed a detailed site restoration and native plant establishment period plan, which included developing monitoring and reporting protocol. Excavation of the marsh created a large open water habitat and a diversity of ecosystems. Over 600 feet of existing stream bank was been preserved and stabilized using bioengineering methods. Native trees, shrubs, and plugs were installed following the native seeding of existing wetland areas and the 20 acre created marsh. ecology provided vegetative monitoring and reporting to ensure compliance with performance criteria prior to acceptance in 2013.
