MCDs and School Districts
MCDs
MCD or Minor Civil Division refers to the governmental and administrative subdivisions within counties. In Michigan, the MCD layer contains township and city data for the state. It is available on the Open Data Portal. In addition, a City layer derived from the MCD layer is also available. The MCD boundaries are maintained by CSS and is updated throughout the year. Currently, updates are released annually, but may be available more frequently in the future.
As stated, these boundaries include county, township, city, village, and county parcels. Local officials come to DTMB-CSS with questions about their municipal boundaries, particularly where annexations are involved. Often, these questions will come in response to information received from the U.S. Census Boundary and Annexation Survey each year. There are two types of annexations found in Michigan: Annexations and 425 Annexations. Both types of annexations are entered into between a city or village and a township for economic development, but there are some important differences. Learn more about annexations on the Annexations and 425s site.
School District Boundaries
Accurate school district boundaries are important for many reasons, including for the dispersion of state and federal funding, proper balloting for elections, and for the public to know what school to send their children to. For these reasons and others, DTMB-CSS is working with both county GIS and the U. S. Census to improve boundary quality.
Under the general category of school districts are the intermediate school districts (ISD). ISDs are the governing body for school districts within its jurisdiction. Additionally, the boundaries of the ISDs are then determined by the school districts they govern. ISDs also oversee any changes to these school district boundaries.
Changes to school district boundaries begin with a petition to the governing ISD. These petitions include a map of the current school district boundary, a map of the proposed change, and a written description of the proposed change. If the ISD approves the school district boundary change, it forwards the decision to the Michigan Department of Education (MDE). After the review, MDE sends approval to the Office of the Great Seal (OGS), who then sends the approved documentation over to DTMB-CSS. CSS staff then updates the official school district map boundaries in the Michigan Geographic Framework (MGF).
U. S. Census School District Review Program (SDRP)
Similar to the Boundary and Annexation Survey discussed in the previous section, the Census School District Review Program (SDRP) allows state officials to review the school district information in census data. State officials provide the Census Bureau with updates and corrections to the federal school district local education agency (SDLEA) codes, school district boundaries, names, grade ranges, and levels for which each school district is financially responsible. The Census asks state officials to review and verify this data annually. (See School District Review Program (SDRP) (census.gov) for additional information.
School district boundary change request process:
Petition is filed with the ISD in which the proposed boundary change would occur.
If ISD approves the change, it goes to MDE.
If MDE approves the change, it goes to the Office of the Great Seal (OGS).
OGS notifies CSS to make the change, and CSS updates MGF and US Census maps.
Questions about school districts or the SDRP
The State Of Michigan also has an Memorandum of Understanding (MOU) with the SDRP for school districts that requires DTMB-CSS to make updates and boundary corrections for the entire state and to the Census data. The point of contact in the State Of Michigan for school district boundary questions or corrections is Tim Lauxmann, Geodata Manager for CSS. For all boundary related questions, contact the CSS staff listed below.
With your email please include a file geodatabase, shapefile, or PDF of the area in question with along with an explanation of what is incorrect, and your contact information. Whether you are a local official with questions about the SDRP data or a parent with a question on where their child will attend school, we can help.
