Flood Insurance: The Risk of Not Being Insured
- Cost of Flooding Tool has been updated and allows users to now embeddable Cost of Flooding Tool on their own website. Users can visit Agents.FloodSmart.gov and click “embed” in the lower corner of the tool. [https://agents.floodsmart.gov/getting-started/the-risk-of-not-being-insured]

Project Data Centers
- C-STORM [cstormdb.erdc.dren.mil] – Basin wave and storm surge database platform, for access to wind, waves, pressure, ice, and water level data at near-shore “Save Points”
Note: This site will start with Lake Michigan data, followed by Lake St. Clair and Lake Erie data. - U.S. Army Corps of Engineers Great Lakes Oblique Photo Viewer [https://greatlakes.erdc.dren.mil/]
Note: This site is currently being moved to a new host and is temporarily inaccessible. This note will be removed when it is back up and running again. - LiDAR [csc.noaa.gov] – High-resolution bathymetric and topographic data housed at NOAA’s Coastal Service Center
- Great Lakes Shoreline Geodatabase (.gdb) [2.4 MB .zip]
- CSHORE [sites.google.com] – CSHORE is a one-dimensional time-averaged nearshore profile model for predictions of wave height, water level, wave-induced steady currents, and profile evolution.
