Map Maintenance

If physical changes to the floodplain have changed the flood hazard information shown on the effective Flood Insurance Rate Map (FIRM), a revision must be requested. Maintaining flood maps is a community’s responsibility and the best way to reflect up-to-date risk information to citizens. It is necessary to identify risk before actions are taken to reduce it. Accurate maps are key to community planning efforts and the preparedness of all citizens during flooding events.

Next Steps

    FEMA and State Entities

  • Review LOMR updates for funding as required
  • Engage with local officials for required assistance
  • Local Community Officials

  • Submit information to CNMS for update
  • Products/Tools Prepared for Use

  • Map Service Center Web Site

Important Points to Remember:

  • If your community is growing, floodplains are changing. Communities should contact FEMA or their State NFIP Coordinator for questions concerning Letters of Map Revision (LOMRs).
  • Development, changes to land use and stormwater management projects result in the continuous need for map updates. Without good representation of the flood hazards, you can’t reduce your risk.
  • Don’t wait for the next mapping project to update your maps. Work with the Floodplain administrator or your State NFIP Coordinator to keep your maps up-to-date through LOMRs.
  • More information is available on LOMRs at http://www.fema.gov/online-tutorials/letter-map-amendment/letter-map-revision-f-tutorial-series-choose-tutorial.

The intent of Risk MAP is to foster awareness public awareness of local natural hazard risk in order to make educated decisions for your home and family. Fully implemented, Risk MAP will result in a more informed public that is empowered to take action to reduce its flood risk. Click here to learn more about what you can do to take action.
