The City of Lafayette is committed to managing a proactive stormwater management program to improve the quality of runoff entering the storm sewer system and receiving streams. The program is regulated by the Clean Water Act under the National Pollutant Discharge Elimination System (NPDES) and is administered by the Colorado Department of Public Health and Environment. 

Annual Report 

To learn more about the city's stormwater program, please view our recent Annual Report. The City's Program Description Document (PDD) is available for public review by contacting us. To report an illicit discharge call 303-661-1277. 


Lafayette joined the Keep it Clean Partnership, a regional stormwater management program, in 2011 to combine resources and implement programs to help improve the stormwater quality entering our streams and lakes as a result of runoff from residential, commercial, and industrial areas, as well as to meet the education requirements of the Stormwater Program. 

Stormwater pollution prevention starts at home with picking up your pet's waste, applying fertilizer to your lawn, or disposing of your chemicals properly. Keep It Clean Partnership provides guidance for residents in these areas to ensure our storm drains and waterways are kept free of pollutants.

Report an Illegal Discharge 

It is illegal to discharge anything other than stormwater (rain and snowmelt) into the storm drainage system (streets, gutters, inlets, drainage ways). Some exceptions may apply. By reporting illegal dumping and discharges, Lafayette can detect and eliminate sources of pollution that are harmful to both people and the environment. 

To report illegal dumping or discharges during business hours, call 303-661-1277 or email. To report pollution after hours, call Boulder County Dispatch at 303-441-4444.
