A computer-based decision-support tool, called the Coastal Protection and Restoration Authority (CPRA) Planning Tool, provided technical analysis that supported the development of Louisiana's Comprehensive Master Plan for a Sustainable Coast through CPRA and community-based deliberations. This document seeks to provide an accessible technical description of the Planning Tool and associated analyses used to develop the Master Plan.

This report highlights RAND’s contributions to the Louisiana Coastal Protection and Restoration Authority’s Master Plan. Its purpose is to help policymakers in other coastal regions understand the value of a solid technical foundation to support decisionmaking on strategies to reduce flood risk, rebuild or restore coastal environments, and increase the resilience of developed coastal regions.

This book is open access under a CC BY 4.0 license. This book takes an in-depth look at Louisiana as a state which is ahead of the curve in terms of extreme weather events, both in frequency and magnitude, and in its responses to these challenges including recovery and enhancement of resiliency. Louisiana faced a major tropical catastrophe in the 21st century, and experiences the fastest rising sea level. Weather specialists, including those concentrating on sea level rise acknowledge that what the state of Louisiana experiences is likely to happen to many more, and not necessarily restricted to coastal states. This book asks and attempts to answer what Louisiana public officials, scientists/engineers, and those from outside of the state who have been called in to help, have done to achieve resilient recovery. How well have these efforts fared to achieve their goals? What might these efforts offer as lessons for those states that will be likely to experience enhanced extreme weather? Can the challenges of inequality be truly addressed in recovery and resilience? How can the study of the Louisiana response as a case be blended with findings from later disasters such as New York/New Jersey (Hurricane Sandy) and more recent ones to improve understanding as well as best adaptation applications – federal, state and local?
