NFIP Map Modernization County Status

Contact: Bruce Menerey 517-335-3181

The Federal Emergency Management Agency (FEMA) began a 5 Flooding -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:

Countywide studies are completed in Barry, Berrien, Cass, Huron, Genesee, Lapeer, Livingston, Macomb, Midland, and Oakland counties.
Preliminary maps are now available for Bay, Branch, Clare, Clinton, Eaton, Jackson, Kalamazoo, Kent, Ottawa, St. Clair, St. Joseph, Sanilac, Tuscola, Van Buren, Washtenaw, and Wayne counties.
Preliminary maps for Calhoun, Gratiot, Ingham, Roscommon, and Shiawassee counties are expected to be available by the end of 2009.
Mapping studies are underway for Allegan, Alpena, Charlevoix, Cheboygan, Chippewa, Grand Traverse, Hillsdale, Ionia, Iosco, Isabella, Leelanau, Lenawee, Manistee, Mason, Mecosta, Newaygo, Monroe, Muskegon, Oceana, Osceola, and Saginaw counties.

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 Grand River (Ottawa County) is an example of a preliminary floodplain map.

The Flood Insurance Study (FIS) for Berrien County is now available:

The DFIRMs for Berrien County, the City of Vassar in Tuscola County, and others will be posted to the Michigan Geographic Data Library. Until they are posted, we can provide completed DFIRMs via our FTP site. Please contact Bruce Menerey, 517-335-3181.
