Severe beach erosion along the Lake Michigan shores at Chicago, 

 Illinois, was counteracted through the use of a submerged sill. The 

 timber structure had a crest elevation 3 feet below normal water level 

 and it successfully retained a beach fill.

This memorandum details the design of a beach fill at Lorain, Ohio. 

 The best alternative solution to stabilize the fill involved the construc- 

 tion of a three-segment, detached breakwater. The structures are situated 

 in accordance with a diffraction analysis discussed in this report. Other 

 design values are also determined.
