Herbert Hoover Dike Rehabilitation – Cutoff Wall Construction
The U.S. Army Corps of Engineers, Jacksonville District, in 2007, placed the Herbert Hoover Dike on the top list of nation-wide dams in need of repair. The Corps is working to rehabilitate HHD, including filling the existing toe ditch, designing and constructing landside seepage management features, installing a cutoff wall, and conducting a variety of studies and technical reviews to help ensure the safety of south Florida residents.
To date, 11 miles of cutoff wall in the 22-mile Reach 1 stretch are under construction or have been completed. Construction of the cutoff wall is providing the internal solution by eliminating existing piping and preventing additional erosion through the dike, foundation and limestone layers.
