Pier repairs scheduled for Portage Lake

Published Oct. 23, 2017

DETROIT – The U.S. Army Corps of Engineers, Detroit District, recently awards a contract for repairs to Portage Lake revetment in Onekama Township, Mich.

The King Co. of Holland, Mich., was awarded a $4.2 million contract to complete critical repairs to the north and south federal revetments. 

The work consists of removal of the existing concrete cap block and a portion of the timber revetment and timber piles; placement of new cantilever steel sheet pile wall, fill, toe, and splash stone and a new 5 feet wide reinforced concrete cap.  A rubble mound wave attenuator will also be constructed on the west end of the south revetment.

“Infrastructure exposed to harsh weather conditions will inevitably need repairs and upkeep,” said Lt. Col. Dennis Sugrue, district engineer, U.S. Army Corps of Engineers, Detroit District.  “These repairs are vital to maintain the structural integrity of the revetments and provide a safe environment as a harbor of refuge.”

Work on the Portage Lake revetment, located east of Lake Michigan, is slated to begin April 2018, and be completed by November 2018.

A major mission of the U.S. Army Corps of Engineers, Detroit District, is maintaining a navigation system that includes 94 harbors and the Great Lakes Connecting Channels that join lakes Superior, Michigan, Huron, and Erie.  The system includes commercial (deep draft) and recreational (shallow draft) harbors, as well as the navigation channels in the Detroit, St. Marys and St. Clair rivers; Lake St. Clair and the Straits of Mackinac.
