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.
