Abstract: Existing stepped-stone revetments along City of Chicago’s Lake Michigan shoreline have deteriorated and are in need of replacement. Timber pilings supporting the revetments have decayed and contributed to the collapse of some of the stones in the revetment. The City of Chicago is interested in replacing the stepped-stone revetments with stepped concrete revetments. Physical model experiments were conducted at the U. S. Army Engineer Research and Development Center Coastal and Hydraulics Laboratory to aid in design of the stepped concrete revetment. The physical model experiments measured overtopping rates during design storm events for several proposed designs for the revetment. Parameters of interest included number and size of steps, elevation at crest, elevation at lakeward edge, and width of promenade.
