Waterway protection Placing erosion control structures on Great Lakes

The area where land and water meet on Lake Michigan and Lake Superior is the most critical space for fish and wildlife habitat and for recreational use. Great Lakes shorelines have many coastal influences that are more like oceans than our thousands of inland lakes. The department understands landowner and municipality concerns about structures that may be at risk from bluff and dune erosion on the Great Lakes and recognizes the large investments residents have in their homes. Shore protection projects are a significant investment and have the potential to impact neighboring properties and the nearshore environment. This information can help landowners invest wisely and protect the Great Lakes environment.

Emergency situations for coastal (Great Lakes) shorelines

The DNR has developed a streamlined temporary erosion control placement authorization process intended for emergency situations for coastal (Great Lakes) shorelines.

  • Review, complete, and submit form 3500-127 to the email address provided in the form.
  • Once you submit the completed form, work on your project may proceed provided it is designed to meet all requirements described in the “Professional Standards” section.
  • Landowners do not need to wait to hear back from the DNR prior to initiating emergency shoreline protection, and the department will continue to allow the placement of temporary emergency material in public water to protect property while a permit is being applied for.
