DETROIT- The U.S. Army Corps of Engineers will place South Haven harbor dredge material near-shore to nourish South Beach starting next week. Sampling results confirm the proposed outer harbor dredge material is suitable for beneficial reuse as nourishment material. About 18,000 cubic yards of material from the federal navigation channel will be placed south of the South Pier in South Haven, Michigan.

Public Notice and Comment Period for the Woodtick Peninsula Section 204 Beneficial Use of Dredged Material for Ecosystem Restoration Project, Monroe County, MI

5/9/2022
The U.S. Army Corps of Engineers (USACE), Detroit District, has prepared a draft Integrated Feasibility Report and Environmental Assessment (IFR/EA) and draft Finding of No Significant Impact (FONSI) for the Woodtick Peninsula Section 204 Beneficial Use of Dredged Material for Ecosystem Restoration Project, Monroe County, Michigan. USACE is undertaking this action in partnership with the Michigan Department of Natural Resources. The purpose of the project is to investigate the feasibility of beneficially using dredged material from the Toledo Harbor Federal Navigation Project for ecosystem restoration purposes at Woodtick Peninsula, located in Monroe County, Michigan. The IFR/EA identifies a Tentatively Selected Plan (TSP: Alternative 4A) for ecosystem restoration that is cost-effective and promotes National Ecosystem Restoration (NER) while protecting the nation’s environment. The TSP consists of dredge material placement and the creation of an in-water artificial reef adjacent to Woodtick Peninsula. This TSP would have a placement footprint of 115.3 acres and require approximately 156,000 cubic yards of dredged material.
