As part of an initiative to create and nourish the northern bank of the bayou in Baton Rouge, Louisiana, over 473 acres of marsh and 11,000 feet of ridge habitat near Lake De Cade was restored. The Louisiana Coastal Restoration and Protection Authority (CPRA) partnered with the National Oceanic and Atmospheric Administration (NOAA) to determine the best solution. In this case, an earthen ridge was constructed to protect and enhance the marsh creation area inland of Lake De Cade. This is an ongoing effort to re-establish land mass and marsh loss that has been occurring in the region for the last century.

“Every acre of marsh we are able to restore means better protection across the state,” stated Bren Haase, CPRA's Executive Director. "It's critical for us to take on projects like this to not just restore what we've lost, but restore wetlands in ways that strengthen them and prevent future deterioration."

After weighing the options, it was decided that the best solution was to install 15,238 square yards of ArmorFlex®, a flexible, interlocking matrix of cellular concrete blocks of uniform size, shape and weight. Benefits of the erosion control system include ease-of-handling and a rapid installation. The $14 million project was funded by the Coastal Wetlands Planning, Protection and Restoration Act to restore habitats like wetlands and barrier islands because they are often the first line of defense to protect coastal communities from damage caused by storms and flooding. In the end, ArmorFlex was a great solution for the site, and Terrebonne Parish, CPRA, and NOAA were pleased with the outcome.

“Terrebonne Parish is delighted with the benefits the completion of this project brings to the parish," concluded Gordon Dove, Parish President. "Over its 20-year-life, this project will create or nourish more than half a square mile of intermediate marsh in a critical area of the parish."
