Discovery Reports

This page links to Discovery Reports for the Great Lakes Coastal Flood Study. FEMA’s Discovery Reports provide users with a comprehensive and holistic understanding of historical flood risk, existing coastal data, and current flood mitigation activities within each lake’s basin. The Discovery Report also provides users with a summary of FEMA’s intent to proceed with a coastal flood hazard study under FEMA’s Risk Mapping, Assessment, and Planning (Risk MAP) program and the Great Lakes Coastal Flood Study (GLCFS) project.
