Illegal Dumping (Illicit Discharge) Report

You may have seen these markings near drain inlets around our city. It is important to remember that both public and private storm drain system are designed to convey only clean rain water, which flows into our local channels, creeks, streams, and eventually the ocean.

Illicit Discharges
An illicit discharge is anything other than clean water entering the storm drain, channel, creek, or stream. By dumping any material other than clean water into the storm drain, you are polluting our local creeks and streams. This pollution impacts your local community financially for clean up and environmentally by harming the natural habitat.

Types of illicit discharge:
  • Direct dumping into public or private storm drains some common illicit material found in storm drains are:
    • Dirt
    • Leaves
    • Paints

    • Trash
    • Used motor oil
  • Construction sites can also contribute to water pollution, by allowing contaminated construction water (concrete, paints, sediment) to discharge into the storm drain.
  • Indirect spills or sewer overflows which could discharge to storm drains or water ways.
