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.  

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.

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. 

PUBLIC EDUCATION AND OUTREACH                                                                                                   

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 AND INVOLVEMENT                                                                                      

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 DETECTION AND ELIMINATION                                                                           

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.

CONSTRUCTION SITE COMPLIANCE PROGRAM                                                                                  

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).

POST-CONSTRUCTION COMPLIANCE PROGRAM                                                                              

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. 

POLLUTION PREVENTION/GOOD HOUSEKEEPING                                                                             

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.  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.
