Chicago Harbor and Lock

The U.S. Army Corps of Engineers (USACE), Chicago District has prepared an Environmental Assessment under the National Environmental Policy Act (NEPA) to evaluate the potential effects of repairing the Chicago Lock’s North Pier Wall located on Lake Michigan in downtown Chicago, Illinois. As part of the 30-day Agency and Public Review period, the Chicago District would appreciate any comments or concerns you might have associated with this work. Comments could include potential effects to lacustrine habitats, threatened and endangered species, cultural resources and social resources.

This project is intended to provide stability to the existing crib structure for a portion of the North Pier. The current sheet pile wall on the river side is supported by tie rods that are corroding and tied to a failing tunnel structure, which require repair or replacement.
