A stormwater management plan outlines how the city intends to meet the requirements of its minimum NPDES permit requirements including:

  • Illicit discharge detection and elimination
  • Industrial inspection
  • Municipal pollution prevention and good housekeeping
  • Post-construction runoff
  • Public education and outreach
  • Public participation and involvement
  • Water quality monitoring and assessment

The Stormwater Management Plan is developed at the beginning of the permit cycle and revised each year based on conditions, ordinance revisions, etc.
