Flood zones are geographic areas the Federal Emergency Management Agency (FEMA) has defined according to varying levels of flood risk. These zones are depicted on a community's Flood Insurance Rate Map (FIRM) or Flood Hazard Boundary Map.   Each zone reflects the severity or type of flooding in the area.  For more information, please see the following:
