The Storm Hill Homeowners Association, whose properties are located on the high ground between Empire’s public beach and the Sleeping Bear Dunes National Lakeshore’s Empire Bluff, applied in June to the U.S. Army Corps of Engineers for a permit to armor the base of their bluff near the shoreline with a 740-foot-long steel seawall along 6 properties—that’s the length equivalent of 2.5 football fields.
