At the meetings, N.C. Floodplain Mapping Office representatives will be available to discuss the maps and latest flood hazard and flood risk data

The North Carolina Floodplain Mapping Office will be holding three public meetings this week to address Onslow County’s preliminary flood maps.

The flood maps indicate areas at risk of flooding and at what level.

High-risk areas are marked on flood maps with the letters A or V, according to North Carolina’s Flood Insurance Rate Maps website, and low-risk areas are marked with the letters X, B, or C.

The preliminary maps unveiled earlier this year more than doubled the number of structures in Jacksonville’s 100-year floodplain: from 509 to 1,366, state documents said.

In Onslow County, the proposed maps put 25 percent more structures in the proposed floodplain and increase the total from 9,133 structures to 11,409.

The public meetings will be held Jan. 25 from 2-4 p.m. at the Onslow County Government Center, 234 NW Corridor Blvd. in Jacksonville, and from 6-8 p.m. at the Sneads Ferry Community Center, 126 Park Lane in Sneads Ferry. Jacksonville Planning and Permitting along with state Floodplain Mapping officials will host a public information session from 4 to 6 p.m. Jan. 26 at Jacksonville City Hall, 815 New Bridge St. 

The areas that will be affected the most by the preliminary maps are the New River, Sneads Ferry and coastal areas.

Flood insurance rates are based on the maps.

At the meetings, N.C. Floodplain Mapping Office representatives will be available to discuss the maps and “latest flood hazard and flood risk data,” Riley Eversull, Onslow County public information officer, said. The maps will be available for viewing at the meetings, and representatives will provide a brief presentation on how their studies are conducted.

“The meetings provide the public the opportunity to review and ask questions about the preliminary copies of the newly updated Flood Insurance Rate Maps (FIRMs) for the county,” Eversull said. “Citizens will be able to discuss how the maps are connected to flood insurance and floodplain management.”
