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 new, 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.

New Bathymetric Lidar for the Lake Superior Shoreline

NOAA Lake Superior Lidar

Using funding from the EPA Great Lakes Restoration Initiative, NOAA Coastal Services Center worked with regional stakeholders, including state agencies, federal agencies, regional working groups, international management bodies, and tribes, to determine the priority areas for collection. The data set was contracted for collection by FUGRO LADS, and excellent communication between CSC and the contractor maximized the quality of the end product. This data set will be critical to the success of many restoration projects, modeling of lake level change, and any analysis that requires a seamless elevation surface above and below the water.

To access the data set, visit http://csc-s-maps-q.csc.noaa.gov/dataviewer/viewer.html?keyword=lidar or, for more information, contact Lindy Betzhold.
