Welcome to the official site for FEMA's Great Lakes Coastal Flood Study, the comprehensive storm and wind study of the Great Lakes basin for the purpose of updating the coastal flood hazard information and Flood Insurance Rate Maps (FIRM) for Great Lakes coastal communities. Below you’ll find a list of the most recent meetings with their agendas, links to preliminary maps, and presentations. To the left you’ll find additional Great Lakes Coastal Flood Study content.

FEMA created this self-guided tutorial on coastal flood mapping that provides important information to coastal communities and their residents. FEMA’s “Coastal Hazards and Coastal Mapping: A Visual Guide” is a glossary of coastal mapping terms and a companion to the tutorial.
