MiEnviro Site Map Explorer Data Disclaimer

• Site Map Explorer uses MiEnviro data combined with data obtained from other agencies or organizations.
• Site Map Explorer is not intended to be used to determine the specific locations and jurisdictional boundaries of wetland areas subject to regulation under Part 303, Wetlands Protection, or critical dune areas subject to regulation under Part 353, Sand Dunes Protection and Management, of the Natural Resources and Environmental Protection Act, 1994 PA 451, as amended.

Using Site Map Explorer

The Site Map Explorer application contains a help section.  Click on the information icon and scroll down below the disclaimer.

The following is intended to be an overview. 

When you first open Site Map Explorer, you see the entire state with many dots.  The dots indicate the number of clustered sites located in the vicinity of the center of the dot.  When the number of sites is less than 11, clicking a dot will expose a list of sites represented by the dot and a link to each.  Zooming in separates the clustered sites into individual sites.

There are several ways to narrow your results. 

1. You can enter keywords in the Search box.  Keywords such as boardwalk, seawall, fill, MSU, UM, Dow, etc. can narrow the results very quickly. 

2. You can zoom in.  Note that many of our older sites map to the center of Michigan's one square mile sections.  View more information about Michigan's sections.

3. You can use the filters.

4. You can use Advanced Search.

Once you've found and selected the site of interest, you will see a site page.  Clicking on the "show more information" link will open a screen with three or four tabs.

• Profile: Basic information is displayed about the site – the Environmental Interest, the address, and additional names/aliases or IDs (e.g., permit numbers) associated with the site.  A sample Profile page is shown below.

• Site Map: The Site Map tab shows all the features relating to the site.  White dots and shapes indicate related sites.  Additional details are provided when clicking any of these items.

• Compliance: The Compliance tab lists inspections, violations, and enforcement actions related to the site.  The filters at the top of the panel can be used to refine the list of evaluations, related violations, and enforcement actions.  Currently, the page can be filtered by environmental program and the time frame in which the evaluations were recorded.  Clicking the arrow next to a record will provide more details including the type of evaluation, violation, or enforcement action and any related notes. Note: Violations assessed prior to August 17, 2015, are not displayed in Site Map Explorer.  This tab does not appear on all sites.

• Documents: The Documents tab lists documents EGLE has published related to the site and links to each.  To download documents, select the checkbox next to the document and click the Download Selected button.
