The Federal Emergency Management Agency (FEMA) has begun a 5
-year program to update the nation's floodplain maps. This program is commonly referred to as Map Mod. The Michigan Department of Environmental Quality (MDEQ) is collaborating with FEMA in this effort through the Cooperating Technical Partners (CTP) Program. The MDEQ is playing an integral role in the mapping program by performing studies, reviewing studies prepared by others, and overseeing the mapping effort in Michigan. You can read more about Map Mod at FEMA's Multihazard Information Platform web site.
The following projects are currently underway or scheduled to be started soon:
-
Countywide studies are completed in the counties of Berrien, Macomb, and Oakland.
-
Preliminary maps are now available for Lapeer, Cass, and Huron counties. Draft maps for Livingston County are currently under review by local and county floodplain officials. Preliminary maps are expected to be complete in the next few months.
-
Preliminary maps for Clinton, Eaton, Ingham, and Wayne counties are expected to be available by spring/summer 2007
-
Detailed mapping studies continue in St. Clair and Washtenaw counties. The maps and study for all three counties should be available by summer/fall 2007.
Once FEMA has completed its production of new digital flood insurance rate maps for a county, the communities within the county will need to consider formal adoption of the new maps to either become eligible to join the NFIP or to maintain participation. The MDEQ has developed model documents for communities to use for the adoption process. Those documents and further discussion can be viewed and accessed on the NFIP Map Modernization Map Adoption page.
The table below lists preliminary floodplain maps that are currently available.
The DFIRM (77 Mb) and FIS (17 Mb) for Berrien County are now available. Note that these are very large files.
The DFIRM for the City of Vassar, Tuscola County can be downloaded as a ZIP file below.
