Floodplain management is the implementation of preventative or corrective measures taken by a community to reduce the impacts of flood damage. Grayson County participates in the National Flood Insurance Program (NFIP) administered through the Federal Emergency Management Agency (FEMA). In order to maintain eligibility, the County Zoning and Floodplain Ordinance contains provisions for the regulation of construction and other activities in designated flood hazard areas of the incorporated areas of Grayson County. These designated flood hazard areas are established by FEMA's Flood Insurance Rate Maps (FIRMs) for Grayson County, which have been incorporated into the official County Zoning Map available through the County's WEBGIS database. More information can concerning floodplain management policies  and practices can be found on the FEMA website at www.fema.gov.

The elevation certificate can also be used to support a request for a Letter of Map Amendment or Revision (LOMA OR LOMR-F).
