The Demolition of Existing Storage Buildings and Construction of New Storage Building at the St. Mary's Falls Canal (Soo Locks), Sault Ste. Marie, Michigan

Expiration date: 3/21/2023

The USACE is proposing the demolition of existing storage buildings and construction of New Storage Buildings at the St. Mary Falls Canal (Soo Locks), Sault Ste. Marie, Michigan. The Soo Locks is listed on the National Register of Historic Properties (NRHP) and National Historic Landmark (NHL). One of the buildings proposed to be demolished West Wing which is a contributing element to the National Historical Landmark. The USACE has determined that the demolition of a contributing building would have an "adverse effect" to the historic nature of the Soo Locks under Section 106 of the National Historic Protection Act. The USACE will be developing a Memorandum of Agreement (MOA) to address these adverse effects which will include recordation of the contributing structures before demolition and the presence of archeological and tribal monitors during ground disturbing work.

Finding of “no adverse effect” under Section 106 of the National Historic Preservation Act (NHPA) for proposed Duluth Ship Canal Protection project.

Expiration date: 4/7/2023

The USACE is seeking to complete the protection of public paths along the shoreline and public park grounds that are adjacent to the Duluth Ship Canal’s North Pier and Lake Superior Maritime Visitor Center by constructing a T-Wall and armor stone revetment on USACE property. In addition, the proposed project will also include the installation of two storm drain substructures that will require re-grading and replacement of concrete within the park grounds adjacent to the Duluth Ship Canal’s North Pier and Lake Superior Maritime Visitor Center. Aesthetic improvements of the public park grounds will also be done as part of the proposed project.
