In the spring of 2018, SCDES BCM 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 and Economic Vulnerability
This application displays the results of the HVA analysis, and provides access to downloadable SCDES BCM GIS data, links to external data sources, and links to the open-source HVA tool and supporting products.
Please read and acknowledge our disclaimer to proceed to the application.

The Hazard Vulnerability Assessment (HVA) tool is an open source geospatial tool that can be used by coastal managers, planners, and researchers to improve hazard mitigation planning, emergency management, post-disaster redevelopment, and to determine areas best suited for restoration and mitigation.
The HVA tool evaluates coastal hazard vulnerability from four components: 1.) Storm surge, 2.) Shoreline change rate (erosion or accretion), 3.) Flooding, and 4.) Social/economic vulnerability (SoVI®). HVA produces several combination products including the following: 1.) Inundation (surge + flooding), 2.) Inundation + SoVI®, and 3.) Shoreline Change (rate, plus temporal and spatial variations). Users can examine each hazard component to see which has the most impact in any given area. The final products are vulnerability indices on a scale of 1 to 5, with 1 being the least risk, and 5 being the most risk.
