The goals of Onslow County’s Floodplain Management Program include providing information about flood hazards, flood safety, flood insurance and ways to protect property from flood hazards and promote natural floodplain functions. The Program also includes administration and enforcement of the Onslow County Flood Damage Prevention Ordinance which outlines the standards for development and construction in the Special Flood Hazard Areas (SFHA). After storm events, Program staff are available to assist property owners in recovery by providing reconstruction guidelines and post-storm mitigation grant resources.
New Flood Maps
New flood maps became effective on June 19, 2020. These maps were adopted in conjunction with an update Flood Damage Prevention Ordinance. The County’s GIS tool, GoMaps, includes layers showing the Historic Flood Maps and the new Effective Maps. The State of North Carolina also has a website, fris.nc.gov, where property owners can find their flood zone and risk.
