2021-01-07T09:43:14-06:00November 23rd, 2020|News, Restoration Plans|

The Louisiana Trustee Implementation Group has released its Final Restoration Plan and Environmental Assessment #7: Wetlands, Coastal, and Nearshore Habitats, and Birds. We accepted comment from August 20, 2020 through September 22, 2020 and held a public meeting on September 2, 2020.

The plan includes projects that restore the Wetlands, Coastal, and Nearshore Habitats and Birds restoration types. It includes five projects which have a total estimated cost of $234.6 million. The selected alternatives are:

Wetlands, Coastal, and Nearshore Habitat:

  • Grande Cheniere Ridge Marsh Creation – This project will create up to 624 acres of marsh near Bayou Grande Cheniere and approximately 12,480 linear feet of earthen ridge along Jefferson Canal. The project estimated cost is $65 million.
  • Terrebonne Basin Ridge and Marsh Creation Project: Bayou Terrebonne Increment – This project will create up to 1,430 acres of brackish and saline marsh and restore up to 80 acres of earthen ridge. The estimated project cost is $157 million.
  • Bird’s Foot Delta Hydrologic Restoration – This project provides engineering and design funding for restoration anticipated to restore the hydrology of the Mississippi River Bird’s Foot Delta by dredging parts of Pass-a-Loutre, South Pass, and Southeast Pass to reconnect the Mississippi River with the marshes of the eastern and central Bird’s Foot Delta. The estimated engineering and design cost is $6 million.

Birds:

  • Isle au Pitre Restoration – This project provides engineering and design funding for restoration anticipated to enhance nesting conditions on the existing island by elevating portions of the island with dredged sediment and planting suitable vegetation for nesting brown pelicans and wading birds, shell rakes for American oystercatchers, and shell or small limestone on the perimeter of the island for tern and black skimmer nesting habitat. The estimated engineering and design cost is $3.5 million.
  • Terrebonne Houma Navigation Channel (HNC) Island Restoration –This project provides engineering and design funding for restoration anticipated to enlarge the island from its current size of 32 acres to approximately 50 acres by importing dredged sediment from a nearby suitable sand source and disposing of it adjacent and onto the existing island. The estimated engineering and design cost is $3.1 million.

The Louisiana Trustee Implementation Group has approved the Final Phase 2 Restoration Plan/Environmental Assessment #1.2: Spanish Pass Ridge and Marsh Creation Project and Lake Borgne Marsh Creation Project.

We released the draft restoration plan in October 2019 and accepted public comment through November 20, 2019. This final plan includes construction activities for the restoration of wetlands, coastal, and nearshore habitats injured in the Louisiana Restoration Area as a result of the Deepwater Horizon oil spill. The plan analyzes restoration project design alternatives for two projects that are components of larger marsh restoration strategies, and were approved for engineering and design (E&D) in a previous restoration plan. We have selected and approved a design alternative for construction of each, with a combined construction cost of approximately $214,932,290.

The Spanish Pass project is a component of an overall large-scale restoration strategy for the Barataria Basin that will re-establish ridge and intertidal marsh habitats degraded due to sea level rise, land subsidence, diminished sediment supply, and storm events. The primary goal of the Spanish Pass increment in this plan is to create and nourish approximately 132 acres of historical ridge and 1,683 acres of marsh. This Plan approves funding for construction, engineering and design, operations and maintenance, and monitoring and adaptive management with an estimated cost of approximately $100.3 million.

The Lake Borgne Marsh Creation – Increment One project is also a component of an overall large-scale restoration strategy for the Pontchartrain Basin that will reestablish the bay rim and intertidal marsh habitat. This increment will create an estimated 2,816 acres of restored marsh habitat at an estimated cost of approximately $114.7 million. This Plan approved funding for engineering and design, construction, operations and maintenance, and monitoring and adaptive management.

Draft Restoration Plan and Environmental Assessment #7:  Wetlands, Coastal, and Nearshore Habitats, and Birds Released

2021-01-07T09:44:08-06:00August 20th, 2020|News, Restoration Plans, Uncategorized|

The Louisiana Trustee Implementation Group has released its Draft Restoration Plan and Environmental Assessment #7: Wetlands, Coastal, and Nearshore Habitats, and Birds. We will accept comments through September 22, 2020.

The draft plan includes proposed projects that restore the Wetlands, Coastal and Nearshore Habitat and Birds restoration types. It includes five proposed preferred alternatives which have a total estimated cost of $234.1 million. The proposed preferred alternatives are:

Birds:

  • Isle au Pitre Restoration – This project would enhance nesting conditions on the existing island by elevating portions of the island with dredged sediment and planting suitable vegetation for nesting brown pelicans and wading birds, long strips of deposited shell (shell rakes) for American oystercatchers, and shell or small limestone on the perimeter of the island for tern and black skimmer nesting habitat. The estimated project cost is $3.5 million (cost is E&D only).
  • Terrebonne Houma Navigation Channel (HNC) Island Restoration –This project would enlarge the island from its current size of 32 acres to approximately 50 acres by importing dredged sediment from a nearby suitable sand source and disposing of it adjacent and onto the existing island. The estimated project cost is $3.1 million (cost is E&D only).

Wetlands, Coastal and Nearshore Habitat:

  • Grande Cheniere Ridge Marsh Creation – This project would create up to 624 acres of marsh near Bayou Grande Cheniere, approximately 12,480 linear feet of earthen ridge along Jefferson Canal, and approximately 48,900 linear feet of earthen containment dike. The estimated project cost is $65 million.
  • Terrebonne Basin Ridge and Marsh Creation Project: Bayou Terrebonne Increment – This project would create up to 1,430 acres of brackish and saline marsh and restore up to 80 acres of earthen ridge. The estimated project cost is $156.5 million.
  • Bird’s Foot Delta Hydrologic Restoration – This project would restore the hydrology of the Mississippi River Bird’s Foot Delta by dredging Pass-a-Loutre, South Pass, and Southeast Pass to reconnect the Mississippi River with the marshes of the eastern and central Bird’s Foot Delta. The estimated project cost is $6 million (cost is for E&D only).

The restoration plan also includes two non-preferred alternatives, which are not summarized here.

The Louisiana Trustee Implementation Group has approved the Final Restoration Plan/Environmental Assessment #5: Living Coastal and Marine Resources – Marine Mammals and Oysters.

We released the draft restoration plan in March 2020 and accepted public comment through April 20, 2020. This final plan will replenish and protect living coastal and marine resources (specifically, oysters and marine mammals) in the Louisiana Restoration Area. One project approved in the plan will focus on increasing capacity to respond to marine mammal strandings, and the other three will focus on oyster restoration in the Louisiana Restoration Area.

We released the draft restoration plan in March 2020 and accepted public comment through April 20, 2020. This final plan will replenish and protect living coastal and marine resources (specifically, oysters and marine mammals) in the Louisiana Restoration Area. One project approved in the plan will focus on increasing capacity to respond to marine mammal strandings, and the other three will focus on oyster restoration in the Louisiana Restoration Area.

 

Marine Mammal Project

The marine mammal project will increase capacity and expand partnerships along the Louisiana coastline for marine mammal stranding response.

  • Increased capacity will lead to improved rapid response to injured and dead dolphins and whales, and a better understanding of the causes of injury and/or death.
  • A Louisiana-based stranding coordinator will build partnerships and conduct outreach for the project.
  • Finally, the project will provide infrastructure, equipment, and supplies needed for stranding and rehabilitation.
  • Estimated cost of this project is $3,095,628.

This project will be led by NOAA in partnership with other federal and state trustees on the Louisiana TIG.

 

Oyster Projects

A network of oyster reefs will be constructed to increase spawning oyster populations.

  • This project will be done in two phases, the first includes construction of two reefs in the Lake Machais/Mozambique Point area and two in the Petit Pass/Bay Boudreaux area, each up to 10 acres in size and 1.2 m from bottom.
  • The second phase will identify and construct additional spawning stock reefs in areas of Louisiana public oyster grounds with suitable conditions for oyster propagation but larval supplies are low.
  • All constructed reefs from this project would be closed to harvest, but located near harvesting areas to promote habitat connectivity.
  • Estimated cost of this project is $9,701,447.

 

Oyster reefs will be created through placement of limestone cultch material.

  • Material will be placed in two locations, the first is a 200-acre site in the Grand Banks area of Mississippi Sound.
  • The second location is at a 200-acre site in Caillou Lake Public Oyster Seed Reservation.
  • We will also identify and construct additional reefs in areas of Louisiana public oyster grounds with suitable conditions for oyster propagation but lack sufficient substrate for oyster populations to expand.
  • Harvest at these sites will be closed until performance criteria are met.
  • Estimated cost of this project is $10,070,000.

 

The Louisiana Trustee Implementation Group will provide funding to support operations at the Michael C. Voisin Oyster Hatchery in Grand Isle, Louisiana.

  • Project activities include production, deployment, and monitoring of hatchery-produced oysters onto established reefs within Louisiana’s public oyster areas that are low-producing or in need of rehabilitation.
  • The hatchery estimates production of at least 500 million oyster larvae per year.
  • A minimum of 25 percent of the oyster larvae produced would be dedicated for oyster restoration activities in protected areas.
  • Estimated cost of this project is $5,850,000.

 

All three oyster projects will be led by the Louisiana Department of Wildlife & Fisheries in partnership with federal and state trustees on the Louisiana TIG. The total $25,621,447 funding proposed for implementation of oyster restoration under the trustees’ preferred alternatives represents a commitment of all remaining available funding for oyster restoration in the Louisiana Restoration Area.
