Lexington County has participated in the National Flood Insurance Program (NFIP) since 1979. The National Flood Insurance Program aims to reduce the impact of flooding on private and public structures by providing flood insurance to property owners, renters, and businesses. It also encourages communities to adopt and enforce floodplain management regulations.

The Federal Emergency Management Association (FEMA) establishes the minimum requirements and guidelines that must be adopted as part of a Floodplain Management Program. In order to further reduce the risk of property damage and lower flood insurance rates for citizens, Lexington County has adopted more stringent regulations. Currently, this affords flood insurance policy holder a 15% discount in flood insurance premium rates. Community Rating System

Flood information is available for properties in the unincorporated areas of Lexington County.  Flood Insurance Rate Maps (FIRM) and Elevation Certificates may be viewed at the Lexington County Administration Building.  The Lexington County Main Library also has a set of FIRM’s for viewing as well as various other helpful brochures

Flood Insurance Rate Maps may be viewed digitally at the FEMA Floodplain Maps application.
