Eustis Engineering will provide geotechnical design services for the highly anticipated Mid-Barataria Sediment Diversion project. The project is expected to get under way soon near Myrtle Grove in Plaquemines Parish.
Engineering, geotechnical, surveying, and other technical services will be included in the Coastal Protection and Restoration Authority’s (CPRA’s) $1.3 billion project.
Because the Barataria basin has experienced significant land loss, the project is seen as necessary. The land loss is due to sediment deprivation, alterations to the area’s natural hydrology, subsidence, sea level rise, and salt water intrusion. Unless action is taken, the land loss will continue.
Goals of the project
The diversion project will be the first controlled sediment diversion reconnecting the Mississippi River with its delta, according to the CPRA.
The project aims to push sediments, water, and nutrients to Barataria basin in order to build and maintain land. As a result, this will increase habitat resiliency to sea level rise and damage from future storm events.
Mid-Barataria is one of eight sediment diversions along the Mississippi River in the 2017 Coastal Master Plan.
“We are excited to be selected to assist in the engineering and design for what CPRA calls the cornerstone project for Louisiana’s Coastal Master Plan,” said Jim Hance, senior project manager and vice president (finance) at Eustis Engineering.
Preliminary designs for the project include an inlet channel, a gated structure at the Mississippi River levee, a conveyance channel, and a gated outlet structure at the future New Orleans to Venice back levee. Additionally, interior drainage improvements, and highway and railroad bridges and alignment accommodations, are planned.
