A U.S. Army Corps study General Reevaluation Report (GRR) is an U.S. Army Corps of Engineers feasibility study that will evaluate the risk of flooding, erosion and damage from coastal storms along the coast of Lake Michigan within areas of the City of Chicago. The study will investigate coastal storm risk, formulate and evaluate potential alternative plans to manage risk and potentially recommend projects for implementation.

The study is cost-shared with the City of Chicago and the Chicago Park District and is estimated to be completed in 2025 and will focus on areas of the lakefront that were not included in the original project and any underperforming segments of the constructed project.

The study is currently undergoing a public scoping period through March 31, 2023 under the National Environmental Policy Act.  Please see the attached documents for more detail. Comments can be provided to chicagoshoreline@usace.army.mil or using the contact form below. 

This project will address significant coastal storm damage experienced along at-risk reaches of the shoreline of Lake Michigan. The study will reevaluate the remaining unconstructed components of the authorized project and other coastal storm damage risk including portions of Lake Shore Drive, Sheridan Road, South Water Purification Plant, and La Rabida Children’s Hospital.

The study objective will be to evaluate and recommend further investment to protect Lake Shore Drive, a major causeway for Chicago, and other infrastructure from coastal storm damage and lakefront erosion in the face of changing climate.

The Chicago Shoreline project was authorized by Congress in 1996. Since then, the U.S. Army Corps of Engineers and our cost-sharing partners the City of Chicago, and the Chicago Park District, have invested over $500 million to rehabilitate and improve the coastal structures protecting Chicago’s lakefront.
