The master plan considered a range of protection and restoration projects that could work together to offer the greatest benefits for the coast. Restoration projects considered include: barrier island restoration, marsh creation, oyster barrier reef restoration, ridge restoration, bank stabilization, shoreline protection, hydrologic restoration, and diversions. Protection projects considered include structural projects (such as earthen levees, T-walls, and floodgates) and nonstructural risk reduction projects (non-residential floodproofing, residential elevation, and residential voluntary acquisition).
Project ideas included in the master plan analysis came from various individuals and organizations, such as citizens, academia, parishes, elected officials, agencies, NGOs, landowners, and businesses/industries. Project costs are expressed in present day dollars and do not include inflation, which allows for an equitable comparison of projects. Only the most beneficial and cost-effective projects are advanced in the plan. The 209 projects evaluated were eventually narrowed down to include the 124 high performing projects recommended by the 2017 Coastal Master Plan. These projects could build or maintain 800 square miles of land, and could reduce flood related economic damage by more than $150 billion over the next 50 years.
