Floodplain Management

The goal of Floodplain Management is to provide educational materials and building oversight in flood prone areas to ensure that property owners take appropriate measures to help minimize the damage that flooding can cause during and after flood events.

Preliminary Flood Maps

On June 30, 2016, the State of North Carolina released new preliminary Flood Insurance Rate Maps (FIRM) for Onslow County.  These updated maps more accurately reflect flood risks than the effective maps as new data and new modeling technology is now available.

These preliminary maps are available to view through the Onslow County Geographic Information Services (GIS) and the North Carolina Flood Risk Information System (FRIS). While the preliminary maps cannot be used for regulatory (permitting) purposes, it is recommended that property owners consider the maps for planning purposes.
