Promontory Point Inspection and Rehabilitation

A beloved historical landmark in the South Side of Chicago, IL, Promontory Point is known for its large limestone revetments which have become a popular attraction for locals. Beginning in the early 2000’s plans for renovation and replacement of the revetments have been proposed, with major pushback from citizens and local preservation societies.

After officials ruled that there was no way to save the stones, as they were crumbling under pressure, McLaren was brought in by Promontory Point Conservancy to conduct an above water and underwater inspection of the waterfront structure to determine the current condition of the revetment, review and update the community funded 2002, 2003, and 2004 marine engineering preservation studies, examine the feasibility of repairing the limestone revetment to meet contemporary damage protection standards, explore various preservation approaches to different sections and conditions, and conduct a cost-benefit analysis.

Conclusion: The limestone revetment currently functions as the original design intended, is not in danger of collapse, and provides adequate shore protection. Additionally, McLaren concluded that, with maintenance and repairs, the service life of the structure can be significantly extended, obviating the need for major demolition and replacement.
