Busy Year for Coastal Restoration in Louisiana

The Restore the Mississippi River Delta organization said in their latest announcement that 2017 has been a busy year for coastal restoration in Louisiana.

Louisiana’s 2017 Coastal Master Plan passed unanimously and progress was made on several large-scale restoration projects.

In their latest post, The Restore the Mississippi River Delta presented a few of the projects that made progress in 2017.

Some of these projects may be bigger and some may be smaller, but they all move us a little closer to a more resilient Louisiana coast,” they said.

  • The Bayou Dupont Sediment Delivery – Marsh Creation and Terracing project is, as its name implies, the third increment of the Bayou Dupont Marsh Creation Project

This project used sediment dredged from the Mississippi River to create and nourish 144 acres of open water and broken marsh and to build nearly 10,000 linear feet of terraces.

The scheme, combined with the Bayou Dupont Sediment Delivery System, Bayou Dupont Marsh and Ridge Creation and the Mississippi River Long Distance Sediment Pipeline projects are part of the Large-Scale Barataria Marsh Creation Project and have restored and nourished more than 1,500 acres of marsh on the Barataria Landbridge.

  • The South Lake Lery Shoreline and Marsh Restoration project was constructed using material dredged from Lake Lery to rebuild its southern shoreline which was damaged by Hurricane Katrina in 2005

Waves in the years since Hurricane Katrina have further damaged the shoreline.

This project restored about 500 acres of marsh and 33,000 feet of the lake’s shoreline.

  • Grand Lake Shoreline Protection project, was constructed this year in Cameron Parish along the southern shoreline of Grand Lake

Erosion of the shoreline of Grand Lake have led to a rapid retreat of the shoreline between 11-32 feet per year.

This project placed rocks near the lake’s shoreline to stop the erosion and promote land accretion between the rocks and the shoreline.

  • Living Shoreline Project is an oyster reef restoration project located along the southwestern shoreline of the Biloxi Marsh

The goal of this project is to create a living shoreline demonstration project displaying how oyster reefs can grow vertically to offset rising sea levels, improve water quality, provide fish and bird habitat and can also be used to combat coastal erosion.

This 21-mile long project will help knock down wave energy before it reaches the shoreline, protecting the marsh behind the reef.

  • Shell Island West is a barrier island restoration project located on the eastern side of Barataria Basin’s barrier island chain

Over the years, Shell Island had been split in two and nearly disappeared beneath the Gulf’s waves. Shell Island East completed construction in 2014.

Shell Island West used sediment dredged from the Mississippi River and from offshore to rebuild 600 acres of barrier island, dune and back barrier marsh habitat.

This project was constructed with funding from 2010 BP oil spill. This restored barrier island will provide habitat to wildlife, separate the Barataria Basin estuary from the salty Gulf, and provide a buffer for interior marshes against waves.
