The Federal Emergency Management Agency (FEMA) recently approved the City of East Lansing's application for a Letter of Map Revision as requested. Based on the information provided, FEMA determined that a revision to the flood hazards depicted in the Flood Insurance Study (FIS) report and National Flood Insurance Program map is warranted. Therefore, the Flood Insurance Study (FIS) report and the Flood Insurance Rate Map (FIRM) have been revised for the reach of Red Cedar River between Bogue Street Bridge and Hagadorn Road Bridge to incorporate the reduction in the floodplain and floodway boundaries from the 1980 FIRM.
In September 2007, the City of East Lansing applied to FEMA for a Letter of Map Revision to officially revise the 100-year floodway, the 100-year, and the 500-year floodplain boundaries of the Red Cedar River in the area located between Hagadorn Road and Bogue Street. Hubbell, Roth & Clark, INC Consulting Engineers (HRC) prepared the floodplain analysis and the application packet for the East Lansing Downtown Development Authority (DDA).
Flood Insurance Rate Map
The Flood Insurance Rate Map (FIRM) for a community depicts the floodplain, the area which has been determined to be subject to a 1% (100-year) or greater chance of flooding in any given year. The floodway is the portion of the floodplain that includes the channel of a river or other watercourse and the adjacent land area that must be reserved in order to discharge the base flood without cumulatively increasing the water-surface elevation by more than a designated height.
FEMA plans to physically revise and republish the FIRM panel and the FIS report incorporating the modifications suggested by the City of East Lansing based on the HRC floodplain analysis report. Then, it would issue preliminary copies for review by the East Lansing community in approximately 3 months.
The insurance rate for the properties located along the Red Cedar River may be positively affected by the reduction of the floodway and floodplain boundaries. Please refer to the attached maps, effective January 30, 2008, that are revised to reflect the approved LOMR.
If you have any questions or concerns about the revised maps or its effects on your property, you may email Cristina Leuca or call her at 517-319-6923, or email Lori Mullins or call her at 517-319-6887.
