Onslow County NC Emergency Preparedness & Hurricane / Flooding Risk Profile

Onslow County on the North Carolina coast is home to Camp Lejeune — the largest Marine Corps base on the East Coast — and Marine Corps Air Station New River. Hurricane Florence in 2018 catastrophically flooded the county with some areas receiving over 30 inches of rain causing billions in damage. The county faces serious hurricane exposure on the southeastern NC coast. The New River and Trent River create additional flooding risk. The military-civilian community interdependence creates complex emergency management requirements.
