Several locations received significant physical impacts. On Wrightsville Beach, North Carolina, Bonnie's erosion caused an inlet to migrate further south. On the northern end of the inlet, a large sand bar developed, partially due to the storm moving offshore sand. Dune sediments were lost during the storm, exposing boardwalk piling. Similarly, on Topsail Beach, North Carolina, the storm breached 27 sand dunes, destroying 60% of the dune line. Sediment from storm washover measured thick behind the beach. Sections of many eroded dunes were re-built using truck loads of sand. Strong waves ran through the foundation of two stilted homes, both of which were later reinforced to compensate for the lost sand.
