Alexis Bay Terrace Project – (Client: Plaquemines Parish)

“For this project, Manchac designed a terrace field in the marshes near the mouth of the Mississippi River. Terraces are earthen features constructed in shallow open water for the purpose of creating habitat, reducing wave energy, and inducing sediment retention. To construct the terraces, native material was excavated from within the project area to build the earthen features. Once the earthwork is complete and the terraces reach the design elevation, the banks will be stabilized by planting of native vegetation. This strengthens the terrace and protects against wave action and currents. This project is funded through FEMA as a result of damages from Hurricane Katrina. Construction began in October 2015 but was delayed due to high river stages. The project is scheduled to be complete by November 2016.”  Directly below are photos of this project as it nears completion.
