Stormwater Management / Illicit Discharges

What is stormwater?

Stormwater begins as rainfall or other precipitation that then flows over land or impervious surfaces and does not soak or percolate into the ground. This stormwater does not percolate into the ground and becomes surface runoff, which flows either directly into surface waterways or it is channeled into drains, which eventually discharge to surface waters. As the stormwater runoff flows over the land or impervious surfaces (paved streets, paved parking lots, and building rooftops), it accumulates and discharges debris, chemicals, sediments or other pollutants to the waterways that could adversely affect water quality if the runoff is discharged untreated.

Illicit Discharge (Dumping)

An illicit discharge is defined as the intentional disposal of any material by placement of and/or directing any material into the stormwater system. Please report suspected illicit discharges of chemicals, paint, oil and grease, yard waste, fertilizer and other questionable materials to local authorities so that it can be investigated. Local ordinances deem it illegal to dispose of any pollutants to the storm sewer.
