New web tool can show shoreline property owners shoreline erosion and historic water levels

Do you have property on the Great Lakes?

Michigan Tech’s Coastal Zone Management WebApp can show you the history of your property’s shoreline and the risk for erosion and bluff retreat. This project documents the Great lakes shorelines over time. The default base map uses 2015/2016 aerial photography from the USDA, from which, users can add layers to view historic water levels, shore erosion, bluffs and 30 year bluff retreat risk area.

The project developed at the Great Lakes Research Center at Michigan Technological University in cooperation with the University of Michigan, is supported by the Michigan Department of Environment, Great Lakes, and Energy’s Coastal Zone Management Program and the National Oceanic and Atmospheric Administration.

Michigan’s water levels are at their highest in more than two decades. From Detroit’s Belle Isle to the U.P.’s Keweenaw Peninsula, these exceptionally high water levels have caused millions of dollars in damage to private property and public infrastructure, including roads and state parks, impacted community water systems and caused public health concerns.
