Flood Risk Reduction
The Louisiana Coastal Protection and Restoration Authority conducts extensive analytical modeling and project evaluations for the State’s Coastal Master Plan (CMP). The 2017 CMP includes 45 risk reduction projects, 13 structural and 32 non-structural projects, for implementation over a 50-year period at a cost of $50 billion dollars. Structural risk reduction projects include earthen levees, flood walls, flood gates, and pump stations. The Lake Pontchartrain Barrier (LPB) structural risk reduction project has projected one of the highest cost-effectiveness values of all CMP projects. Hydrodynamic and risk reduction modeling to evaluate conceptual design alternatives for the LPB will be presented.
