Protecting Michigan's Sand Dunes

Agency: Environmental Quality


Sleeping Bear Dunes Michigan sand dunes are a resource of global significance; they are the largest assemblage of fresh water dunes in the world. There are about 250,000 acres of sand dunes in Michigan of which about 70,000 acres are classified as critical sand dune formations. The Michigan Legislature has found that the critical dune areas of this state "are a unique, irreplaceable, and fragile resource that provide significant recreational, economic, scientific, geological, scenic, botanical, educational, agricultural, and ecological benefits to the people of this state and to people from other states and countries who visit this resource".

Mining of sand is recognized as an important economic benefit to the foundry and construction industries of Michigan. Other contour changes and developmental activities in critical dunes require review at the local or state level to ensure the integrity of critical dunes are protected.

The DEQ, working with a stakeholders group, has completed review of public comments regarding proposed revisions to the following procedures: "Measuring Heights and Slopes Under the Critical Dune Area," "Activities Not Constituting a Use Under Part 353," and "Review of Cantilevered Portions of Buildings." These three procedures are now updated and the final documents available through the following links. If you have questions regarding these procedures, contact Jim Milne at 517-373-4608.
