Stormwater Management

The Municipality is in compliance with the U.S. EPA's Phase II Stormwater Rule, which establishes stormwater management programs for municipal separate storm sewer systems (MS4). MS4 programs are intended to improve the waterways by reducing the quantity of pollutants that stormwater picks up and carries into storm sewer systems during storm events. The program is designed to satisfy the appropriate requirements of the Clean Water Act via implementation of the following six minimum control measures:

  • Construction Site Runoff Control
  • Illicit Discharge Detection and Elimination
  • Pollution Prevention/Good Housekeeping
  • Post-Construction Runoff Control
  • Public Education and Outreach
  • Public Participation and/Involvement
