5 Coastal Reclamation Projects Protecting Louisiana Pipelines

           

Thousands of miles of pipeline canals that once cut through the Louisiana now look like straight, green lines reaching into the Gulf. The North Lake Mechant, East Calcasieu Lake, South Terrebone, New Orleans East Landbridge, and Belle Pass-Golden Meadow are 5 projects that are protecting Louisiana pipelines.

Those canals once made the flow of oil and natural gas possible. Now, they make it impossible to keep the salt water from flowing inland and eating away at the wetlands.

Since wetlands absorb the forces of floods and storms, protecting them also protects coastal oil and gas infrastructure from storm surges.

The Situation

It’s hard to say how much of Louisiana’s oil and gas infrastructure is at risk from the receding coastline. One Bloomberg article estimates it to be $100 billion worth of ports, refineries, tanks, and pipelines.

We do know that some 20 square miles of coastal land are disappearing every year. Taking with it the marsh that protects the vast pipeline network laid over the years. More than 610 miles of pipeline could be exposed over the next 25 years, according to an LSU study.

This loss of barrier islands and swampland is also creating an increased flood risk. Without that natural buffer to soak up the rainfall, storms will be more likely to cause historic flooding.

The Path Forward

We’ve known about these problems for years. That’s why Louisiana is spending much of its share of the 2010 Deepwater Horizon oil spill settlement on coastal restoration.

Louisiana’s master plan for coastal reclamation and hurricane protection includes marsh creation projects in the Barataria and Terrebonne basins, and projects protecting coastal and lake shorelines in western Louisiana.

The plan includes guidelines for flood-proofing businesses, elevating houses, and teaching residents how to safely evacuate from areas when they’re at the highest risk of flooding.

The master plan includes risk reduction and restoration projects. It addresses barrier island restoration, sediment diversion, hydrologic restoration, and structural protection. Here’s a brief overview of five of the plan’s coastal reclamation projects and what the state hopes to achieve.

North Lake Mechant

Terrebonne Parish is at risk of nearly half of its area disappearing over the next several decades, according to the Coastal Protection and Restoration Authority. That’s why the goal of the $1 billion project is to revive ~13,000 acres of marsh in central Terrebonne.

The new marsh will extend from Lake De Cade to Lake Mechant, acting as a bulwark against future land loss. The project is also restoring a critical landbridge barrier between Bayou De Cade and Lake Mechant. Click here for more information about North Lake Mechant Landbridge Restoration.

East Calcasieu Lake

The Coastal Protection and Restoration Authority estimates Cameron Parish will lose more than 440 acres over the next 50 years. That’s more land than any other parish.

The East Calcasieu marsh project is a $1.1 billion project. It’s expected to reclaim 17,000 acres of marsh in the east Cameron-Creole watershed over the next 13 years. Click here for more information about Cameron Creole Watershed Grand Bayou Marsh creation.

South Terrebonne

With a $1.8 billion price tag, the most expensive restoration project in Louisiana’s 50-year coastal master plan will generate 25,000 acres of marsh west and south of Dulac, between Bayou du Large and the Houma Navigation Canal.

According to the coastal master plan, Dulac, Cocodrie, Chauvin, and neighboring communities remain at high risk of flooding. This project will take 18 years to complete. Click here to read more about Terrebonne Parish and the environmental dangers the Master Plan addresses.

New Orleans East Landbridge

On the east side of Lake Pontchartrain, some 21,000 acres are being restored after the destruction of tropical storms.

This project (expected to take another 21 years to complete) will protect the Orleans Landbridge. Thus protecting the fish and wildlife dependent on these marsh habitats.

The $1.5 billion undertaking will also protect communities along the lake. Click here for more information about New Orleans Landbridge Shoreline Stabilization & Marsh Creation.

Belle Pass-Golden Meadow

Lafourche Parish could lose 41% of its land over the next 50 years. This project aims to reverse the trend by creating 25,000 acres of marsh over the next two decades, costing roughly $1.6 billion.

The revitalized wetlands span 20 miles of Bayou Lafourche, between Golden Meadow and Port Fourchon. Click here for more information about West Fourchon Marsh Creation & Nourishment.
