What is Stormwater?

  • Downstream flooding
  • Stream bank erosion
  • Increased turbidity (muddiness created by stirred up sediment) from erosion
  • Habitat destruction
  • Changes in the stream flow hydrograph (a graph that displays the flow rate of a stream over a period of time)
  • Stormwater Damage
  • Contaminated streams, rivers and coastal water

Stormwater in Richland County

The Richland County Commissioners adopted the Stormwater Management and Sediment Control Regulations for Richland County. The purpose of these regulations is to reduce Stormwater and erosion impacts from earthmoving and/or construction activities. Anyone within Richland County limits (not inside city/village limits, except Lexington Village) with a project that will entail earth disturbing or construction activity, must apply for a Stormwater Permit. The permit process requires the applicant to submit a site plan detailing how erosion and Stormwater will be handled during and after the project. The goal is to keep sediment from leaving the site and to handle Stormwater in a way to promote water infiltration into the soil and not create a drainage nuisance to neighboring properties. Larger commercial construction projects may be required to submit an engineered plan that will retain Stormwater onsite and release it at a controlled rate.
