CWPPRA and the Public Working Together

CWPPRA projects are science-based and initiate wetland restoration which is crucial to not only sustain Louisiana’s fisheries but also to protect the region’s people and resources [2]. CWPPRA relies on local input to develop projects that best serve affected residents and invites citizens to participate in project planning and selection” [2].

IMG_5174CWPPRA aims and encourages public participation to all CWPPRA meetings in which community knowledge that has been passed down from generation to generation may provide insight about environmental change [1]. As CWPPRA provides public education and involvement, communities “see firsthand how change is impacting their environment and have modified their behaviors to become better environmental stewards” [2].

Restoration activities include meetings and becoming knowledgeable about protection and restoration plans. Citizens who experience flooding, channel navigation, offshore fishing and boating are encouraged to participate in all CWPPRA public meetings.

A WaterMarks interview with Don Davis of LSU SeaGrant mentioned that he believes coastal land loss is a social problem in which families who have lived in the region for more than (7) generations need an active role in finding affordable and workable solutions [1]. Ultimately Davis mentioned that each community requires solutions to coastal land loss to be affordable and have the capacity to proceed quickly with brutal honesty [1].

Bayou Dupont Sediment Delivery – Marsh Creation and Terracing


Wetlands in the Barataria Basin were historically nourished
by the fresh water, sediment and nutrients delivered by
the Mississippi River and its many distributary channels.
These sediment and nutrient inputs ceased following the
creation of levees along the lower river for flood control and
navigation. In addition, the construction of numerous oil and
gas canals along with subsurface oil and gas withdrawal has
exacerbated wetland loss in the area. From 1932 to 1990, the
Barataria Basin lost over 245,000 acres of marsh. From 1978
to 1990, the area experienced the highest rate of wetland loss
in coastal Louisiana.

The primary goal of this project is to create and nourish
approximately 144 acres of emergent intermediate marsh
using sediment from the Mississippi River, and constructing
9,679 linear feet of terraces. The proposed project includes
dredging sediment from the Mississippi River for marsh
creation by pumping the sediment via pipeline into an area of
open water and broken marsh. The proximity of the project
to the Mississippi River provides a prime opportunity to
utilize this renewable river sediment resource. The strategy
includes utilizing the access route and infrastructure
previously put into place for the BA-39 project. This project
will complement existing restoration projects in the area.

CWPPRA Region 2, Barataria Basin, Jefferson and
Plaquemines Parishes. The general project area is about 10
miles south of Belle Chasse, LA and is west of LA Hwy
23 and north of the Myrtle Grove Marina. The project
is immediately adjacent to the completed CWPPRA
Mississippi River Sediment Delivery System – Bayou
Dupont (BA-39) project.

The project was approved for engineering and design at the
January 24, 2013 Task Force meeting. The E&D was
completed in the fall of 2014 and sponsors requested phase
2 funding at the January 22, 2015 Task Force meeting,
however, there was insufficient money available to fund
the entire project. In order to take advantage of the existing
mobilization of the Long Distance Sediment Pipeline
(LDSP) Project, the sponsors proposed to reduce the scope
of the project to fit within the available CWPPRA funding.
The Task Force approved the reduced scope Phase 2 funding
request at the May 14, 2015, Task Force meeting. The asbuilt
project features include 144 acres of marsh creation and
9,679 linear feet of terracing.

In addition, CPRA increased the marsh creation feature of
the project by utilizing contingency funding left over from
BA-43, thereby increasing the total marsh creation in the
area to an estimated 296 acres. Construction started in April
2016, and marsh creation was completed in November
2016. Terracing was completed in June 2017, and vegetative
plantings for the terraces are scheduled for the spring of

This project is on Priority Project List (PPL) 22.
