Floodplain Management
Floodplain Regulations
Richland County participates in FEMA's National Floodplain Insurance Program (NFIP) which allows all homeowners in Richland County to purchase flood insurance. As part of this program, we are required to implement certain flood management regulations in order to ensure that proper development within the floodplain is occurring and mitigate the overall effects that each particular development may have on neighboring properties. A copy of the current regulations is found below.
