Two stacked-block revetments, the product of emergency conditions and budget limitations, were constructed at Illinois Beach State Park on Lake Michigan in April 1982. The revetments, designed to protect a large, rapidly eroding recreational beach that has been developed in beach and dune sand, were constructed of 4 multiplied by 4 multiplied by 3 foot concrete blocks produced from local waste ready-mix. Intended to be an emergency measure, the structures have proved to be stable, durable, and attractive.
