Town of Kiawah Island staff conducted a GPS survey of the dune line before and after Hurricane Matthew. The pre-storm survey was conducted on Oct. 5 and the post-storm survey was conducted on Oct. 10. Surveys were conducted using a survey grade GPS with submeter accuracy. Overall, Kiawah’s beach suffered extensive erosion but no homes were impacted by erosion. Beach walkovers sustained significant damage and almost all walkovers will require inspection and repairs. Kiawah’s extensive dune system performed its role exactly as it should have. The role of dunes is to sacrifice themselves to protect inland areas. This is exactly what occurred. Beaches are extremely resilient and eroded sand will slowly make its way back up onto our beaches and dunes will begin to rebuild naturally.
