The AOC has been undergoing an $80 million cleanup to remove contaminated sediment and restore the degraded wetland habitat along the river. It extends along the southern shoreline of Lake Michigan from its headquarters at the lagoons in Marquette Park in Gary to the Indiana-Illinois border in Hammond. Cardno restored the native wetland and riparian corridor habitat along a 1.8 mile stretch of the East Branch Grand Calumet River in northwest Indiana.
While a key driver for the project is sediment remediation, the project is also actively restoring aquatic ecosystems, water quality, and poor substrate conditions through integrative management and restoration techniques. The project is being led by the Great Lakes Sediment Remediation LLC joint venture. Key agency partners also include the Indiana Department of Natural Resources, Indiana Department of Environmental Management, and Natural Resource Damage Trustees.
Cardno performed key environmental consulting and restoration services to restore native wetlands along portions of the southern shoreline of Lake Michigan.
