The Barrier Island System Management (BISM) program has been developed by the Louisiana Coastal Protection and Restoration Authority (CPRA) through facilitation by the Water Institute of the Gulf (the Institute). BISM is intended to be a holistic and systemwide approach to manage the entire barrier island and headland chain through restoration and maintenance, replacing a project-based prioritization approach previously adopted as part of the Louisiana Coastal Master Plan. Because BISM will be a new effort within CPRA, processes must be developed to identify:

  • How restoration of barrier islands should be prioritized
  • Methods for leveraging existing synergistic programs within CPRA, such as the Louisiana Sediment Management Program (LASMP) (including the Louisiana Sand Resources Database (LASARD) and Louisiana Sediment Availability and Allocation Program (LASAAP)) and the Barrier Island Comprehensive Monitoring (BICM) program
  • Strategies for optimizing program implementation
