Critical Dune Areas Program

The Great Lake coastlines have extensive coastal dunes on Lakes Michigan and Superior. In the 1980’s it became apparent that development pressures had potential to impact the future of Michigan’s dunes as they became increasingly popular sites for recreation and residential development. In 1989, approximately 74,000 acres of dunes along 265 miles of coastline were identified as needing protection from developmental pressures and designated as Critical Dunes. 

These Critical Dune Areas represent a diverse cross-section of dune shapes, height, and vegetation along Lake Michigan’s shoreline in the lower and upper peninsulas, and the shore of Lake Superior. 

The Critical Dune Areas (CDAs) include public lands and private properties where developmental, silvicultural, and recreational activities are regulated and a permit is required under Part 353, Sand Dunes Protection and Management, of the NREPA. The law balances the benefits of protecting, preserving, restoring and enhancing the diversity, quality, functions, and value of the critical dunes with the benefits of economic development, multiple uses, and public access.

Information on specific sites:
District Permit Staff

The boundaries of regulated dunes and adjacent lands, commonly called critical dune areas or CDAs, were drawn on the maps of 19 lakeshore counties and their townships.

The CDAs are a combination of coastal barrier dunes, land that has dune-like features, and unique plant communities. Regulatory authority goes to the water’s edge. A permit is required for a regulated use in a CDA.

Apply for a permit

A property owner may choose to meet with their local EGLE staff person during a pre-application meeting to discuss their proposed project.  This is an optional service available to the property owner prior to their completing and submitting a permit application.

Applications for pre-application meetings and individual permits are submitted through MiEnviro Portal. Additional information about the application process is available at EGLE/USACE Joint Permit Application. Once a permit application is received, EGLE staff review the application and visit the project site to assess the proposed impacts to the CDA. The status of all permit applications may be tracked at MiEnviro Portal. A valid permit may be transferred to a new property owner with the written permission of the current permittee. A request to transfer a permit is submitted in MiEnviro Portal.

Every application must include a completed online form, property owner authorization, property location, a permit from the local health department if proposing a new or replacement septic system, a soil erosion and sedimentation control permit or waiver from the local soil erosion and sedimentation control permitting agency, and a vegetation assurance. The proposed impact must be identified and quantified, and a site plan and cross-section submitted.

Invasive Species Management

Invasive species are a major threat to the diversity, quality, and functions of the CDAs. Invasive species change the plant diversity of the dunes by displacing native plants which degrades the quality and function of the CDA. Trees hold land together and are a stabilizing force against erosion. Trees, such as hemlocks or oaks that die because of an invasive species no longer provide those long-term benefits to the function of the CDA.

Depending on the type of invasive species, a variety of management techniques may be used to control and manage their spread on your property and adjacent properties. You can work with your local Cooperative Invasive Species Management Area (CISMA) staff to address specific species found at your project site.
