PROJECTS IN CONSTRUCTION

The purpose of this project is to install a floodgate in Bayou Chene in St. Mary Parish to reduce backwater flooding from the Atchafalaya River during a Mississippi River high water event. The project will provide backwater flooding protection for portions of St. Mary, Terrebonne, Lafourche, Assumption, Lower St. Martin and Iberville parishes, reducing flood risk to communities and infrastructure and promoting resilience.

This project includes improvements to the existing Wax Lake Outlet Campground in the Atchafalaya Delta WMA to enhance recreational opportunities for hunters, anglers, wildlife viewers, and campers by offering a safe, protected campsite that is accessible by boaters. Project features include bulkhead installation along the campground approximately 30 feet from the existing shoreline, sediment placement behind the bulkhead to restore some of the lost acreage of the campground, and jetty construction to stabilize the bank and bulkhead.

This project involves the construction of multiple features in Cypremort Point State Park in St. Mary Parish to enhance recreational and educational opportunities, including reinforcing the existing rock embankment on Quintana Canal; restoring the public beach; installing a new marsh boardwalk; repairing and upgrading existing roads and parking areas damaged by repeated flooding; and constructing a new RV campground with up to 30 pull-through sites.

PROJECTS IN ENGINEERING AND DESIGN

The purpose of the project is to utilize freshwater and sediment from the Atchafalaya River in order to build, sustain, and maintain wetlands within the Terrebonne Basin. The project intends to dredge the GIWW east of the Atchafalaya and install a bypass structure at Bayou Boeuf Lock to increase freshwater and sediment flows from Atchafalaya River to Terrebonne marshes in St. Mary and Terrebonne parishes.

COMPLETED PROJECTS

Projects Completed in 2021

This project involves dredging two locations in the Atchafalaya Delta in St. Mary Parish to enhance recreational access for hunters, anglers, and wildlife viewers to Breaux Pass, Cul-de-sac Pass, and many interior waterways and wetlands in the Atchafalaya Delta WMA. Dredged sediment will be beneficially used to enrich and nourish wetlands.

Projects Completed in 2018

This project provides for flood protection improvement to the current Morgan City flood protection system by raising nearly two miles of existing levees to elevations as identified in the 03/27/2013 report by T. Baker Smith.

This project provided flood protection improvements by raising or improving 2.5 miles of the current levee system in the Morgan City area in St. Mary Parish.

Projects Completed in 2015

The objective of this project is to reduce commercial traffic through residential neighborhoods in Morgan City and provide better access to the industrial facilities and the museum by rerouting traffic onto a newly constructed roadway. The new roadway is located along the protected side of the Morgan City Floodwall beginning at the at the floodgate on 2nd St., connecting to 2nd St. and Federal Ave. and ending at the tie into Industrial Road.

This project involved construction of the second phase of a levee, flood wall, sinkable barge structure, and pump station on Franklin Canal in St. Mary Parish to prevent storm surge from inundating the town of Franklin.
