Fourth Report of the National Academy of Engineering/National Research Council Committee on New Orleans Regional Hurricane Protection Projects: Review of the IPET Volume VIII (2008)

Each report is produced by a committee of experts selected by the Academy to address a particular statement of task and is subject to a rigorous, independent peer review; while the reports represent views of the committee, they also are endorsed by the Academy.

This report from the National Academy of Engineering (NAE) and the National Research Council (NRC) is a review of Volume VIII of the report from the Interagency Performance Evaluation Task Force (IPET). The IPET was established in 2005 to evaluate the performance of the New Orleans hurricane protection system during Hurricane Katrina. Volume VIII of the IPET report evaluates risk and reliability of the New Orleans hurricane protection system and contains information central to understanding the likelihood of future flooding across the region. The NAE/NRC report finds that the interim draft of Volume VIII is incomplete. Although the risk analysis method used in Volume VIII appears to be appropriate, further information will have to be presented to adequately explain and validate the method used and results obtained.
