Stormwater Management

Stormwater runoff occurs during rain storms and when snowmelt flows over land surface such as roads, driveways, parking lots and rooftops . These surfaces prevent water from soaking into the ground.

Stormwater runoff goes to local streams, lakes, and rivers through thousands of street curb inlets and miles of pipes.

Stormwater runoff carries pollutants such as sediment, nitrogen, phosphorus, bacteria, oil and grease, trash, pesticides and metals.

To reduce pollution impacts on urban streams, the Environmental Protection Agency expanded the Clean Water Act in 1987 to require that municipalities obtain National Pollution Discharge Elimination System (NPDES) permits for stormwater discharges.

The City of Olathe adopted Title 17 Stormwater Management regulations required to minimize the impacts of urban development and protect water quality. Six minimum control measures are required:

  1. Public education and outreach
  2. Public participation and involvement
  3. Illicit discharge detection and elimination
  4. Construction site runoff control
  5. Post construction runoff control
  6. Pollution prevention for municipal operations.
