Illicit Discharges

Oil spill

The Stormwater Ordinance prohibits the discharge, disposal, pouring, or dumping of any pollutant into the storm drainage system. Only rain water runoff is generally allowed in the storm drain. Some discharges are specifically allowed, such as lawn watering and residential vehicle washing. For a detailed list of exemptions please refer to the ordinance.

Chemical spills that may enter the drainage system must be immediately contained. “Dry” clean-up methods such as sweeping or absorbance materials should be used. Those responsible for the property where a spill or illicit discharge has occurred must notify the City at Stormwater Hotline 303-655-2120 - within one working day. Other notifications may also be required (Federal, State, County, Local Health Department, etc).

The ordinance also prohibits pipes or ditches that can carry sanitary waste to storm drains or directly into streams. Discharges from these connections are illegal and must be removed as soon as possible.

Residential and commercial property owners must ensure that leaves, material waste and dirt do not enter storm drains, street gutters or ditches. Please do your part to keep our streams and ponds clean.
