The Terrebonne Basin Barrier Shoreline Restoration Project is an ecosystem restoration
effort to reconstruct coastal landforms of the barrier shoreline to maintain the
integrity of the Terrebonne Basin barrier shoreline system and increase habitat
availability for migratory birds, wildlife, and aquatic organisms. The location
for this project is the Isles Dernieres (Raccoon Island, Whiskey Island,
Trinity Island, and East Island) and Timbalier Island (Timbalier Island, and
East Timbalier Island) barrier island chains located in Terrebonne and Lafourche
parishes.
The project will investigate introducing sediment to this sediment-starved system,
reducing the current number of breaches and enlarging the width and dune crest of
the islands. Some features being considered to meet project objectives are island
nourishment using offshore sand sources, offshore wave breaks, feeder berms, strategic
use of vegetative plantings, sand fencing, and bayside marsh creation.
