Coastal Erosion Update

The Great Lakes coast is a very dynamic environment. Water levels on Lake Michigan have been below average since the 1980’s, until recently. There is now a greater potential for shoreline erosion and ultimately bluff failure. This website is designed to provide information to homeowners and local governments on what government resources may be available to assist with shoreline erosion.

FAQ

  • Question: Do I need permission or a permit to protect my shoreline from erosion?
  • Yes. State law requires any material that is placed in the Great Lakes be authorized by the WI Department of Natural Resources. Furthermore, additional DNR permits may also be needed to:

    • Authorize earth-moving (grading) activities on the shoreline needed to stabilize the slope of a bank.
    • Authorize removal of material below the Ordinary High Water Mark (dredging), in order to properly install material to stabilize the base of the slope.

    For more information on how to start planning and getting permits to place shore protection structures on the Great Lakes, please visit: http://dnr.wi.gov/topic/waterways/shoreline/greatLakesErosionControl.html

  • Question: Can I place materials to address erosion without a permit in an emergency?
  • Yes. Even though State law requires any material that is placed in the Great Lakes be authorized by the WI Department of Natural Resources, the DNR will allow temporary emergency material to be put into place without a permit as long as the landowner gets approval form the department and actively begins design and approval for a permanent solution.
