EAC Consulting, as part of its Continuing Services Agreement with the Corps of Engineers, was tasked with rehabilitating a 3.7-mile portion (Reach 1B) of the Herbert Hoover Dike. The Dike was constructed in the late 1960s to provide flood and storm water control protection for South Florida. The project limits start at Sand Cut and extends to the southwest to Canal Point. The quantity of seepage was a major concern and the USACE engaged EAC team to find design solutions to mitigate seepage. The EAC team conducted subsurface investigations, geological explorations, laboratory testing, slope stability, seepage and critical sections analysis. Specific design elements included the design of a seepage berm, a drainage swale, relief trenches, relief wells, cutoff walls and structural designs for Culvert C-13 and the S-352 spillway structure. The goal of the project was to improve the integrity of the dike structure within Reach 1B.
