Herbert Hoover Dike Culvert Project, Port Mayaca, FL
The Government analyzed a number of critical infrastructure facilities nationwide in the wake of the levee failures in New Orleans during Hurricane Katrina. The Herbert Hoover Dike around Lake Okeechobee was determined to need major upgrades to its levee and water control structures. The Culverts 11 & 16 Replacement Project was one of the contracts awarded to replace two of the 32 water control structures around the lake. All of these structures have experienced significant deterioration over their 80+ year life span and require replacement and improved functionality.
Note: Since the award of this contract, Harry Pepper has been awarded 5 additional culvert replacement projects on the lake, doubling that of our nearest competitor.
