Flood Hazard Mitigation Plan to help  
Reduce Our Natural Hazard Risks

The below links are the City of Savannah's IMG_5241.JPGFlood Hazard Mitigation Plan. The Plan is part of an annual process being undertaken by the City that reduces flood insurance premiums by 25% for Savannah homeowners, and aids the City’s ongoing floodplain and storm water management efforts.
  • The purpose of the Flood Hazard Mitigation Plan is to assess current flood hazard conditions, including historically flooded areas and the most critical repetitively flooded properties, and to develop appropriate mitigation strategies for the City to consider in reducing or eliminating future flood losses. Upon completion of the plan, the City of Savannah intends to continue its aggressive floodplain management efforts by evaluating, targeting and applying for Federal grant funds to assist in the implementation of future flood hazard mitigation projects.

    Because of the City of Savannah’s participation in this process, FEMA will reduce flood insurance premiums by 25% for all property owners insured through the National Flood Insurance Program.

    The final Flood Hazard Mitigation Plan will be prepared and submitted for adoption by the City Council. The adopted plan will be a stand-alone document that will be utilized to update the Flood Hazard section of the Chatham County Multi-jurisdictional Hazard Plan to provide greater focus and attention to the City of Savannah in reducing its current and future flood hazards.

    Should you have any questions about Savannah’s Flood Hazard Mitigation Plan, please contact Tom McDonald, Development Service Administrator, at (912) 651-6530, extension 1895.

More Flood Safety Tips:
When the City is experiencing heavy rains and localized flooding, we recommend that you take the following precautions:

  • Do not drive through standing water; it may be deeper than it looks.
  • Drive slowly through ponding water, so waves do not cause damage to other vehicles or nearby homes.
  • Do not remove manhole covers to release flood waters; this backs up the sewer system.
  • If flooding occurs, the City will barricade affected streets and will monitor and strictly enforce all street closures.
  • Please remember, when traffic lights are out in an intersection, it becomes a 4-way stop, and you must yield to the person on your right before proceeding.
  • To learn more information see: Flooding - In General.
