SC Realtors Backs LiDAR Flood Mapping Bill S.108

COLUMBIA, S.C. (March 29, 2021) – South Carolina has experienced some of the most historical flooding in the last decade. It has become abundantly clear that our coastal state is susceptible to flooding. According to the South Carolina Emergency Management Division (SCEMD), the state's low-lying topography, combined with its humid subtropical climate, makes it highly vulnerable to inland or riverine flooding. Current flood maps in South Carolina provide an idea of what areas within the state may be flood prone with some maps not being updated since 2007.

“This type of mapping hinders the state from adequately preparing for storms and other natural, potentially life threatening occurrences,” said Nick Kremydas, CEO of SC REALTORS®.

Charleston Senator, Chip Campsen, sponsored a new bill (S.108) which would require the SC Geological Survey Unit at the Department of Natural Resources (DNR) to update topographic mapping using Light Detection and Ranging (LiDAR) technology. It provides quick, affordable and accurate elevations throughout floodplains. The bill states that data collection must comply with Federal Emergency Management Agency (FEMA) standards and that the data collected would be provided to DNR’s flood mitigation program. The legislation would also require that the maps be made available to the public, governmental agencies, and appropriate private industry.

“SCR works diligently to provide support and promote quality of life for all South Carolina residents,” continued Kremydas. “We are proud to support lawmakers in their efforts to update statewide flood mapping so that risk information may be shared more effectively.”

S.108 recently received enough votes to pass the Senate on March 9, 2021 and is currently with the Agriculture, Natural Resources and Environmental Affairs committee in the House.
