Floodplain Management


Full Announcement  

Lexington County Floodplain Management Plan 


Lexington County has participated in the National Flood Insurance Program (NFIP) since 1979. The purpose of the Lexington County Floodplain Management Program is to protect the lives and property of the citizens who build in a floodplain.


Lexington County, as a participant in the National Flood Insurance Program (NFIP) and the Community Rating System (CRS), offers flood information for property located in the unincorporated areas of Lexington County.  Flood Insurance Rate Maps (FIRMS) and Elevation Certificates may be viewed at the Lexington County Administration Building.  The Lexington County Main Library also has a set of FIRM maps for viewing as well as various other helpful brochures.  Flood Information can be viewed digitally under the GIS Property, Mapping and Data Service link.  For any information about the National Flood Insurance program in Lexington County please contact Christopher Stone at 803-785-8121.


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 not only help protect structures, but to also help lower flood insurance rates, Lexington County has adopted more stringent regulations.


While Lexington County may determine a property or structure is out of a flood hazard area, flood insurance may still be required at the discretion of the mortgage company.

Participation in the NFIP also means, in most cases, federal assistance would be made available in the event of a flood.

Lexington County Floodplain Management Outreach Project


South Carolina DNR Flood Mitigation




Lexington County is working to become less vulnerable to flooding, and your participation is important to us! The County is preparing a Floodplain Management Plan which will identify and assess our community’s flood hazard risks and determine how to best minimize or manage those risks and what outreach materials may be necessary to better communicate those risks.

The following link is the draft Hazard Identification and Risk Assessment (HIRA) section of the Flood Mitigation Plan.  We welcome your comments on this draft section. The information you provide will help us better understand your hazard concerns and can lead to mitigation activities that help lessen the impacts of future hazard events. Please e-mail your comments to by July 24, 2017

Thank you for your input!
