Abstract:

The Corps of Engineers proposes to mitigate shore erosion in the vicinity of Port Sanilac Harbor, Sanilac County, Michigan, that is attributable to the Federal navigation structures at the harbor. Studies have determined that erosion attributable to the navigation project is approximately 43.0 of the total erosion due to all causes. The plan considered most practical for this purpose entails creation of a feeder beach and a subsequent periodic nourishment of the area suffering shore damage. Approximately 90,000 cubic yards of fill material will be required initially and 30,000 cubic yards of fill will be required periodically approximately annually for an undetermined number of years. The establishment and sustenance of such a beach will provide the quantities of littoral material interrupted by the navigation project to the shore downdrift. Author
