Community Rating System Program
Most homeowner insurance policies do not cover damages caused by flooding from storm events. Properties that have been officially identified as being in floodplains are required by their mortgage lenders to have flood insurance.
All affected property owners should consider obtaining flood insurance, which is available at reduced cost to affected City residents and businesses. Properties in the City of Decatur are eligible for a 15 percent discount on the typical cost of flood insurance by virtue of the City's participation in the Federal Emergency Management Agency's Community Rating System (CRS) program and having qualified as a category 7 community.
The Engineering Department provides general flood plain information free of charge to City residents to assist them in determining if their properties are affected by flood plains. If needed for insurance or other purposes, a resident can obtain an official flood plain determination letter for a $10 fee.
More information is available on the Federal Emergency Management Agency (FEMA) website and www.FloodSmart.gov. Or, you may contact your mortgage lender, insurance company or the Engineering Department at 404-377-6198 for more specific information.
Revised Floodplain Map
The City wide Letter of Map Revision (LOMR) which became effective on February 20, 2008 has been superseded through the Map Modernization Program for the State of Georgia as part of a Cooperating Technical Partner (CTP) agreement with FEMA, the Georgia Emergency Management Agency (GEMA) and DeKalb County. The revised Flood Insurance Rate Maps (FIRM) and Flood Insurance Study (FIS) received final approval from FEMA in early 2013 and became effective on May 16, 2013. The Map Modernization Program inventoried and analyzed the runoff generated with each of the City’s 4 drainage basins to current FEMA standards and criteria. This information has developed new floodplain limits for the Base Flood Elevation (BFE), the 1-percent storm return frequency used by FEMA for all floodplain mapping. The BFE floodplain limit means the flood has a one-percent chance of being equaled or exceeded in any given year. The revised FIRM mapping eliminates all previous studies and revisions approved by FEMA including the City’s LOMR effective February 20, 2008. The revised floodplain map (see link below) can be used by individuals to view the extent of the floodplain’s impact on specific properties or within the City in general.

All elevation certificates produced or surveys conducted to establish the limits of the floodplain on specific parcels of land on or after May 16, 2013 must utilize the data and elevation information contained with the approved revised FIRM and FIS issued by FEMA. Elevation Certificates must be prepared using the form effect at the time of preparation, see the FEMA website for information on the form to be utilized. The Flood Insurance Rate Map (FIRM) panel maps, Flood Insurance Study (FIS) profiles and flow rate data issued by FEMA on February 20, 2008 for the City’s LOMR have been superseded by the revised FIRM and FIS. Please open and review the complete revised FIRM and FIS documents approved by FEMA to obtain general Base Flood Elevation (BFE) and any other data normally obtained from the superseded FIRM panels and FIS study. Detailed BFE data must be obtained from the Engineering Department and has to be interpolated from the waterway Profiles found in the FIS, not from the FIRM panel maps. Copies of this information can be obtained from the Engineering Department. The cost of obtaining copies will be the cost of their reproduction. Should you require additional information or clarification on the impact of the floodplain for any property within the City please contact the Engineering Department at (404) 377-6198 for assistance.

The Engineering Department also retains on file all Elevation Certificates for specific properties within the City that have processed a Floodplain Development permit, filed for Flood Insurance and provided the City with a copy of the Elevation Certificate that was filed within their insurance agent or coordinated Base Flood Elevation determination with the Engineering Department. These Elevation Certificates are available at the link below.
Decatur Receives FEMA Flood Grant
November 2007 – The City of Decatur has received a $1,239,962 federal grant to purchase four properties on Westchester Drive that are seven feet below base flood elevation and have been flooded many times. The houses on the properties will be demolished and the land will be left as greenspace.
The grant was awarded by the U.S. Department of Homeland Security’s Federal Emergency Management Agency. FEMA has invested $3,240,053.95 in projects to reduce residential flooding in Decatur and three other Georgia communities: Savannah, DeKalb County and Douglas County. Decatur’s grant was the largest of the four awarded.
