Regulatory Program
The City of Charleston Stormwater Regulatory Program works to protect water quality for our residents, businesses, and visitors.  This program also reviews development/redevelopment for impacts to flooding.  The best known components of this program are the regulation of new development and redevelopment for Stormwater, but the total Program consists of the following 6 primary areas: 

  • Public Education and Outreach – Engaging the Public on How to Protect Our Environment Relating to Stormwater.  The City partners with the Ashley Cooper Cooperative Extension to leverage the resources of many municipalities in the area in providing educational opportunities for residents, home owners associations, and businesses to improve their management of Stormwater quality 
  • Public Participation and Involvement – Providing opportunities for the public to weigh in on Stormwater program priorities  
  • Illicit Discharge Detection and Elimination (IDDE) – Identifying unauthorized release of pollutants into the Stormwater system through active inspection and investigation.  These items can include direct discharges of washing machines into Stormwater drainage, improper disposal of grease, and many other situations. 
  • Construction Site Stormwater Runoff Control – The regulatory review process of controlling pollutant discharge from active construction sites. 
  • Post-Construction Stormwater Management in New Development and Redevelopment  - The regulatory review process for providing permanent features to provide Stormwater quality.  
  • Pollution Prevention/Good Housekeeping for Municipal Operations – Operating an inspection and maintenance program to prevent pollution from City operated facilities.

This Program operates to satisfy requirements of the South Carolina Department of Health and Environmental Control (SCDHEC) Stormwater Program, which is in turn the delegated authority for the State of South Carolina to implement the Environmental Protection Agency (EPA) mandated National Pollutant Discharge Elimination System.
