Species Benefiting From Restoration:
   White shrimp (Litipenaeus setiferus)
   Brown Shrimp (Penaeus aztecus)
   Blue Crab (Callinectes sapidus)
   Red Drum (Sciaenops ocellatus)
   Atlantic croaker (Micropogonias undulates)
   Black drum (Pogonias cromis)
   Spotted sea trout (Cynoscion nebulosus)
   Southern flounder (Paralichthys lethostigma)
   Sheepshead (Archosargus probatocephalus)

Acres of Habitat To be Restored:
Approximate total of 22,500 feet of linear terraces

Project Summary:
Based on survey information available, areas with an average water depth of 3.0 feet or less were targeted. An approximate total of 22,500 feet of linear terraces would be constructed. This includes approximately 17,500 linear feet of small terraces, and 5,000 linear feet of large terraces. The terraces would have a 1:4 side slope, an initial height of +4 ft. NAVD88, and a settled height of +2.5ft. NAVD88. The smaller terraces would have a 10 ft. crown and the larger terraces would have a 25ft. crown. The terraces would be planted with four rows of smooth cordgrass (2 rows per side) and 2 rows of marshhay cord grass on the crown. The terrace field alignments will be designed to ensure
maximum reduction in wave energy, thereby increasing shoreline protection benefit as well as habitat benefits.

Project Objectives:

  • Terraces will be constructed utilizing a marsh buggy, excavator and backhoes. Depending on soil conditions, adjacent borrow areas may be staggered and will likely parallel the terrace. Terraces will be planted once construction is complete.
  • The entire project area will be monitored for a minimum of five years, in keeping with the NOAA requirements for successful restoration implementation.
  • In years one and two, the plan shall include quarterly evaluation of the emergent vegetation and the presence of adjacent submerged aquatics and the ability of the terraces to withstand disturbance caused by human or natural activities. In years three and four, monitoring activities will be conducted every six months. Monitoring shall be conducted at least once during year five, depending upon lessons learned from prior monitoring. Additional monitoring shall be conducted if warranted.

Outreach Efforts:
In addition to outreach support offered by BTNEP, TPCG will provide regular, bi-monthly project updates to the membership of the Coastal Zone Management and restoration Advisory Committee; the Terrebonne Parish Council (these proceedings are televised on HTV and the Parish public access channel, TPTV). Quarterly updates will be provided to the Houma-Terrebonne Chamber of Commerce Coastal Advisory Committee and the South Central Industrial Association, and quarterly updates will be submitted to area newspapers for publication.
