When should I request a map revision to the Flood Insurance Rate Map? |
If physical changes to the floodplain have changed the flood hazard information shown on the effective National Flood Insurance Program (NFIP) map, a revision should be requested. The request should be accompanied by the appropriate portions of the MT-2 application/certification forms package, entitled "Revisions to National Flood Insurance Program Maps" (FEMA Form 81-89 Series), and the required supporting information. |
