Terrebonne Basin Barrier
Shoreline Restoration Project

The goal of the Terrebonne Basin Barrier Shoreline Restoration (TBBSR) Project is to investigate the feasibility of reducing the prolonged degradation and erosion of the Terrebonne Basin barrier islands in order to achieve a sustainable coastal ecosystem that can support and protect the environment, economy, and culture of southern Louisiana. The TBBSR Project, which was initially identified in the Louisiana Coastal Area, LCA - Ecosystem Restoration: Comprehensive Coast-wide Ecosystem Restoration Study, was authorized through the 2007 Water Resources Development Act.

The objectives of the TBBSR Project include:

  • Minimize future land loss, and restore the geomorphic function of the Terrebonne Basin barrier islands;
  • Restore and improve essential habitat;
  • Protect vital socioeconomic resources; and
  • Reduce damage from wave energy on interior bays and marshes.

The task objective of the SJB team is to provide comprehensive services for project and program management support. The SJB team serves as the project liaison for the Louisiana Department of Natural Resources (LDNR). More specifically, the SJB team provides services to assist the LCA project team (in coordination with LDNR and the U.S. Army Corps of Engineers) with the development and completion of Project Feasibility, Engineering, and National Environmental Policy Act reports.

The Project reports will consist of the compilation and thorough review of all relevant information. Specific tasks include Spatial Analysis of Island Retreat, Sea Level Rise and Subsidence Computations, Erosion Analyses, Cross-shore Sediment Transport Analyses, Island Restoration Designs, Borrow Area Designs, Breakwater and Terminal Structure Optimization Modeling and Designs, Final Environmental Impact Study, NEPA Report, LCA Feasibility Study-2010 Update, Project Delivery Team Program Analysis, Cost Estimating, and Full Participation in the USACE 6-Step Planning Process, including the requisite WVA and IWR computations, which will lead ultimately to selection of the final recommended array of alternatives.
