Remediation and Restoration Projects for Detroit River AOC

Remediation projects for the Detroit River AOC.

Project Title	Project Description	Date Completed	Targeted BUI(s)
Hennepin Marsh	Plans call for rebuilding existing shoals to stabilize the area, such as installing submergent and emergent woody debris, stone spawning beds, stone habitat structures, and a tern habitat shoal.	Ongoing	Loss of Fish & Wildlife Habitat Degradation of Fish & Wildlife Populations
Sugar Island	This project aims to stabilize and restore 1,000 linear feet of coastal shoreline to help protect the island from severe erosion and create 5 acres of marsh and submergent habitat to benefit both aquatic and terrestrial species.	Ongoing	Loss of Fish & Wildlife Habitat Degradation of Fish & Wildlife Populations
Belle Isle Forested Wetland Restoration	This project aims to restore surface water flow patterns critical to the flatwoods by removing former roads and trails, conserving special species of concern, and re-establish native vegetation.	Ongoing	Loss of Fish & Wildlife Habitat Degradation of Fish & Wildlife Populations
Upper Riverfront Parks Habitat	This project involves improving and restoring of approximately 1,000 ft of shoreline with native wetland edge and fish spawning habitat; establishment/enhancement of upland native vegetation for birds, mammals, and pollinator species; and the creation of approximately 7 acres of aquatic habitats.	Ongoing	Loss of Fish & Wildlife Habitat Degradation of Fish & Wildlife Populations
Monguagon Creek GLLA	The project will result in the remediation of contaminated sediments (petroleum compounds, PAHs, PCBs and heavy metals (mercury)) in Monguagon Creek and downstream in the Detroit River.

Upper Trenton Channel Project	Sediment remedial feasibility study, design and partnership recruitment is on-going at the Upper Trenton Channel in the Detroit River to remediate sediment contaminated with PAHs, PCBs, mercury, and high pH.

Detroit River Walk GLLA	This remediation project addressed 13,000 yd³of PAH, cyanide, mercury, and lead contaminated sediments.	2020	Degradation of Benthos Fish Tumors or Other Deformities Bird or Animal Deformities or Reproduction Problems Restrictions on Fish and Wildlife Consumption Restriction on Dredging Activities
Stony Island	This project created 3,500 linear feet of rock shoals, 600 linear feet of vegetated shoal and installed roughly 100 new habitat structures that provide homes for fish, turtles, snakes, amphibians, and birds.	2018	Loss of Fish & Wildlife Habitat Degradation of Fish & Wildlife Populations
Detroit River Fish Spawning Reefs: Belle Isle reef; Grassy Island reef; and, Ft. Wayne reef	This project constructed three four-acre fish spawning reefs in the Detroit AOC. The Belle reef off the NW side of Belle Isle was completed in 2016. The reefs off Grassy Island and Ft. Wayne were established in 2018.	2016; 2018	Loss of Fish & Wildlife Habitat Degradation of Fish & Wildlife Populations
Harbortown Sediment Site Characterization	This sediment site characterization included approximately 2 miles of the Detroit River from the MacArthur Bridge at Belle Isle to the Renaissance Center in downtown Detroit.	2016	Degradation of Benthos Fish Tumors or Other Deformities Bird or Animal Deformities or Reproduction Problems Restrictions on Fish & Wildlife Consumption Restriction on Dredging Activities
Mid-lower Trenton Channel Sediment Site Characterization	This sediment site characterization included the Detroit River from the Grosse Ile toll bridge to the south end of Calf Island.	2015	Degradation of Benthos Fish Tumors or Other Deformities Bird or Animal Deformities or Reproduction Problems Restrictions on Fish & Wildlife Consumption Restriction on Dredging Activities
River Rouge/Ecorse Sediment Site Characterization	This sediment site characterization included approximately 3 miles of the Detroit River from the Rouge River Cut Off Channel to Ecorse Creek.	2014	Degradation of Benthos Fish Tumors or Other Deformities Bird or Animal Deformities or Reproduction Problems Restrictions on Fish & Wildlife Consumption Restriction on Dredging Activities
South Fishing Pier	Three breakwater barriers and three rock underwater berms were built to protect the newly created aquatic fish nursery habitat. The nursery consists of three 0.2-acre deep pools.	2013	Loss of Fish & Wildlife Habitat Degradation of Fish & Wildlife Populations
Blue Heron Lagoon Restoration	This project connected the lagoon to the Detroit River to provide a zooplankton-rich nursery for fish larvae to thrive. A 0.5-acre peninsula of wet prairie, two vernal pools, and a turtle nesting area were also constructed.	2013	Loss of Fish & Wildlife Habitat Degradation of Fish & Wildlife Populations
USS Shoreline Project	This project restored upland and shoreline habitat along 1,000 feet of Detroit River along the US Steel 80” mill property and created habitat for reptiles and amphibians.	2013	Loss of Fish & Wildlife Habitat Degradation of Fish & Wildlife Populations
Shoreline Restoration at Wayne County's Refuge Gateway	This project restored 28 acres of wetland, controlled phragmites along 2.5 miles of shoreline, restored 25 acres of upland buffer habitat, and controlled invasive species on 50 acres of upland habitat.	2013	Loss of Fish & Wildlife Habitat Degradation of Fish and Wildlife Populations
Ralph C. Wilson Centennial Park	This Project consists of capping approx. 3.8 acres of contaminated sediments. There is also a significant habitat restoration component consisting of a Water Garden, soften shoreline and a fish reef. PAH’s are the main contaminant of concern.
