The U.S. Army Corps of Engineers released the Louisiana Coastal Protection and Restoration (LACPR) draft final technical report in March, 2009. In response to federal legislation, the Corps had to analyze hurricane protection, and design and present a full range of measures to protect against a storm equivalent to a category 5 hurricane. The request included measures for flood control, coastal restoration, and hurricane protection, and stipulated close coordination with the State of Louisiana and its appropriate agencies. This is the second and final report from the National Research Council (NRC) Committee on the Review of the Louisiana Coastal Protection and Restoration (LACPR) Program. The committee was charged to review two draft reports from the LACPR team and to assess the hurricane risk reduction framework, alternatives for flood control, storm protection, coastal restoration, and risk analysis. This report presents this committee's review and advice for improvements of the LACPR March 2009 draft final technical report.
During the past 50 years, coastal Louisiana has suffered catastrophic land loss due to both natural and human causes. This loss has increased storm vulnerability and amplified risks to lives, property, and economies-a fact underscored by Hurricanes Katrina and Rita. Drawing Louisiana's New Map reviews a restoration plan proposed by the U.S. Army Corps of Engineers and the State of Louisiana, finding that, although the individual projects in the study are scientifically sound, there should be more and larger scale projects that provide a comprehensive approach to addressing land loss over such a large area. More importantly, the study should be guided by a detailed map of the expected future landscape of coastal Louisiana that is developed from agreed upon goals for the region and the nation.
Louisiana's coastal wetlands represent a significant natural and economic resource for the state and the nation but have been disappearing at a rate of 25 to 35 square miles each year. In the past 50 years, more than 1,500 square miles have been lost. The wetlands contain 95% of all marine species in the Gulf of Mexico, 30% of the nation's fisheries, and one of the largest habitats in the world for migratory waterfowl. More than 25% of all oil and gas used in the United States originates or passes through these wetlands, which also serve as a buffer for hurricanes. The State of Louisiana asked ASCE to convene a summit to discuss technical aspects involved in carrying out restoration programs and to report on the insights that could be drawn from the summit. This report provides conclusions and recommendations concerning the technical topics discussed at the summit as well as the Task Committee's recommendations for a path forward.
