The United States Coast Guard was looking to repair a damaged 200-meter section of SEAWALL in Algonac, Michigan. The city found that the seawall failed because The Coast Guard had dredged the adjacent St. Clair River bottom too excessively. A 1997 U.S. Army Corps of Engineers Dredging Permit allowed the Coast Guard to dredge next to the seawall. In exchange for another 20-year lease on the site, The Coast Guard has agreed to pay for the repairs. Working with geotechnical engineers at Testing Engineers and Consultants, I developed a series of drawings to restore the Algonac seawall. The new design required the addition of two, one foot wide, double channel steel wales to support the 200 meters of existing sheet piling. Connected to the wales will be helical anchors attached 70 feet back to a 10-foot tall below-grade concrete slab.
