Construction within Special Flood Hazard Areas

The County's first Flood Insurance Rate Map Effective Date was December 1, 1982.  If a structure was built prior to this date and is located in a Special Flood Hazard Area, the structure may not be elevated to current standards.  This may result in an increased flood insurance premium.

Floodplains have an essential role in flood protection.  Floodplains provide room for floodwaters, reducing pressure on dams and levees.  It is critical that floodplains remain free of debris or hazardous waste to reduce the risk of injury in the event of a flood.
