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. 


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.

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, call 303-661-1277. 

Learn more about illegal dumping and discharges and how to help keep these items out of our waterways. 

Lafayette strives to incorporate a variety of strategies to ensure residents and business owners have access to education materials. Visit The Keep it Clean Partnership to learn about how to prevent stormwater pollution from your business or home.
