On January 29, 2013, President Obama signed into law the Disaster Relief Appropriations Act, of 2013 (Public Law 113-2), to assist in the recovery in the aftermath of Hurricane Sandy. As part of the law, the Congress tasked the Corps to work with a variety of partners to conduct a comprehensive study of the coastal areas affected by Hurricane Sandy to evaluate flood risks and, that as part of the study, to identify areas warranting additional analysis and institutional and other barriers to providing protection. (Chapter 4 of Public Law 113-2). The Comprehensive Study is designed to help local communities better understand changing flood risks associated with climate change and to provide tools to help those communities better prepare for future flood risks. It builds on lessons learned from Hurricane Sandy and attempts to bring to bear the latest scientific information available for state, local, and tribal planners. In addition to State, regional, and local governments, FEMA, NOAA, multiple DOI agencies and HUD were major contributors to this study.
