In the spring of 2018, DHEC-OCRM performed a hazard vulnerability assessment within the South Carolina Critical Area. The critical area is defined as coastal waters, tidelands, beaches and beach/dune system. The assessment was performed using the Hazard Vulnerability Assessment (HVA) tool. The HVA tool is an open-source geospatial tool that evaluates coastal hazard vulnerability from four components:
1) Storm Surge 2) Shoreline Change 3) Flooding 4) Social & Economic Vulnerability
