Westminster operates a stormwater utility to serve its residents. North of 92nd Avenue, all stormwater accumulated from gutters ultimately flows into Big Dry Creek. South of 92nd Avenue; all accumulated stormwater ultimately flows into Little Dry Creek.

The primary goal of the City of Westminster Stormwater Program is to reduce the amount of pollutants entering Little Dry Creek and Big Dry Creek. Pollutants such as fertilizers, pesticides, sediments, hydrocarbons, trash and spilled chemicals may be transported by storm water from residential, commercial and industrial areas into the storm sewer system ending up in our local waterways, causing water pollution.  

Oversight of the stormwater program is carried out by the Engineering Division of the Community Development Department located within City Hall.  However, all city departments work hard to be a key to success for the stormwater program implementation. Program oversight and some maintenance activities are funded by the enterprise.    

The purpose of the city's stormwater program is to ensure compliance with state and federal regulations. Coordination of the implementation and enforcement of the program areas listed is directed toward protecting the city's natural resources, ensuring public safety and continuing to improve the quality of life of all residents. Per the MS4 General Stormwater Permit issued by the Colorado Department of Health and Environment (CDPHE), the City of Westminster must develop and maintain records of it's Stormwater Program in the form of a Program Description Document (PDD).   A copy of the PDD is available for public comment and review; please contact Jacob Moyer at jmoyer@cityofwestminster.us with any inquiries.

The goal of the Public Education and Outreach Program is to increase public awareness of local water quality problems caused by urban environments. This ranges from education to helping individuals change their daily actions, to community activities supporting the stormwater program. This program takes into account pollutants commonly associated with the urban environment.

Public participation/involvement is often discussed in the context of the public education measure because they share a common goal – reaching out to citizens to improve awareness and achieve program compliance. The distinction between the two programs is that public participation/involvement provides a conduit for citizens to participate in the development and implementation of the publicly funded stormwater program.

Illicit discharge is in essence illegal dumping. The goal of the Illicit Discharge Detection and Elimination Program is to reduce the frequency and impact of illicit discharges to the environment in which pollutants are intentionally or accidentally discharged into the storm sewer system. Documentation and supplementary material will provide greater insight to the process of illicit discharge elimination and types of illicit discharges and enforcement procedures laid out by the City of Westminster.

Which businesses are more likely to illegally discharge?

REPORT AN ILLICIT DISCHARGE

You can report any probable illicit discharge by calling our Stormwater Hotline at 303-706-3367 or by emailing stormwaterhotline@cityofwestminster.us.  Please provide the location, responsible party (if identified), and a description of the source and nature of the illicit discharge.

*Please note that City Hall hours are Monday through Thursday 7 a.m. to 6 p.m. If your report occurs outside of these hours, please leave a voicemail or email and the city will respond within these business hours. If you feel that the report is an emergency that needs immediate response, please call Westminster dispatch at 303-658-4360.   

The goal of the Construction Sites Compliance Program is to reduce sediment and other construction-related pollutants from entering the Municipal Separate Storm Sewer System (MS4). The city is committed to the enhancement and protection of existing development, streams, lakes, wetlands and rivers that may be impacted by sediment laden runoff and encourages builders to maintain the natural balance between sediment supply and transport.

It is also the city's policy to encourage erosion control by leaving land undisturbed as long as possible (by project phasing) and using temporary and permanent erosion control Best Management Practices (BMPs).

Under city code, the City of Westminster has the authority to issues Notices of Violation (NOV's) as well as Stop Work Orders for any developer or contractor that does not comply with sediment and erosion control measure requirements. All of our stormwater information related to construction sites can be found through eTrakIT.  Here is a list of contractors in 2018 that have a list of violations along with their respective eTrakIT identifications.

  • Thrive Home Builders (Hyland Village Subdivision) - ENG14-9916
  • Pradell Builders (Taiva Professional Campus) - ENG18-0046
  • PCL Construction Services (Gregory Hill Pump Station) - ENG17-0122
  • Lokal Homes (Hyland Village Subdivision) - ENG17-0116
  • Bailey Construction and Consulting (Alamo Draft House) - ENG17-0117
  • Connor & Gaskins Unlimited LLC (Park Centre Place, Uptown Suites) - ENG17-0092

Although the City of Westminster is fairly strict concerning construction site non-compliance; we do pride ourselves on our compliance assistance within the program. City officials are here to serve the community and help in any way that we can, which is why our city inspectors are trained to not only point out issues with particular sites, but also help toward fixing these issues surrounding compliance in a way that can strengthen our community and culture in relation to the environment.  Supplemental material has been provided in the space below related to city expectations for construction compliance.

The goal of the Post-Construction Compliance Program for the City of Westminster is to implement planning procedures and enforcement mechanisms to reduce stormwater impacts resulting from areas of new development and significant redevelopment. 

Private storm sewer structures, such as ponds, bioswales and underground storage tanks must be properly maintained. The City of Westminster Engineering Division works directly with property managers, HOA's and commercial property owners to achieve this goal. Long-term maintenance of drainage structures is needed to ensure systems continue to function per designed, preventing flooding, erosion and water quality degradation of our local lakes and streams.

Property owners are required to inspect and maintain private ponds, bioswales and/or underground storage tanks. Inspections and repairs must be documented and available upon request. Additionally, businesses operating on the property are not allowed to discharge anything but naturally occurring stormwater runoff into the stormwater system. This includes preventing materials stored outside from leaking, draining, spilling or being dumped into the stormwater system.

The goal of the Pollution Prevention/Good Housekeeping for Municipal Operations Program is to reduce the amount and type of pollution that is generated by municipal operations or from municipally-owned property such as sediment, hydrocarbons, trash and debris, nutrients and metals.  The City of Westminster’s goal is to set an example in the community by preventing stormwater pollution while carrying out numerous municipal activities that have the potential to impact water quality.  These activities include, but are not limited to the maintenance and repair of City streets, the maintenance of public parks and recreational areas, and the maintenance of municipal facilities.
