Sustainable City Operations

Sustainability Highlights


The City purchases vehicles with the most efficient gas/diesel mileage appropriate for their use. As new technologies come to the market, the city will consider purchase of those vehicles. Currently, the city has 35 hybrid vehicles including hybrid police interceptors, two Toyota Prius, and three plug-in hybrids (Chevy Volt). The City has two electric motorcycles for use in City parks and open spaces and one fully electric vehicle for parking operations. 

Clean Energy

70% of the City's occupied buildings source their electricity from 100% solar sources. The City partners with SUNSHARE, a community solar garden provider, to source this electricity. In addition, photovoltaic solar panel arrays are mounted on City Park Rec Center, Westview Rec Center, the MAC, and the Public Safety building. 

The City has over 30 solar-powered LED parking lot lights throughout Downtown and City Hall.


The city is constantly improving the energy efficiency of its buildings through HVAC upgrades and lighting projects. The city is in the process of developing a sustainable city building policy that will cover new construction, renovations and operations and maintenance.

Capital Improvement Projects

The City uses sustainability criteria to evaluate and improve long-term capital projects. The Envision rating tool is currently being used to evaluate some Public Works projects and we have one Envision Silver Certified building (solid-waste dewatering facility). All new City buildings are required to meet a LEED Silver Certification. 


SolSmart Gold Designated Community: SolSmart recognizes cities, counties, and regional organizations for making it faster, easier, and more affordable to go solar. Read about the recognition!

"Clean Air Champion" Award, Winter 2022: Regional Air Quality Council (RAQC) recognized the City of Westminster as a “Clean Air Champion” for its work in reducing emissions by supporting electrification efforts and promoting low/no emission transit options.

Colorado Solar Friendly Communities, Platinum-level Certification: Recognition for resident and installer friendly solar permitting and review processes 

Colorado Clean Commute Approved: The Sustainability Office worked with our local transportation management agencies, Smart Commute and Commuting Solutions, to become Colorado Clean Commute Approved! The City completed an assessment about our workforce, conducted employee surveys, and were presented with a trip reduction plan that outlines clean commute suggestions.

Progress Reports

Sustainability Examples 

  • The city's reclaimed water system treats waste water for use in landscape irrigation. By build out, the system will save 3,500 acre feet of water, enough to supply 8,150 single family homes with all of the water they would need for a year.
  • The city purchases over 4.2 mega watts of energy from community solar gardens for city facilities, saving the city $30,000 per year in energy costs and reducing the city's green house gas emissions. By the end of 2022, over 60% of the electricity sourced for City facilities will be from community solar. 
  • Westminster in a Platinum Level Solar Friendly Community and a SolSmart Gold designated community, and we have the numbers to prove it. As of 2017, 1,632 single-family homes have solar installed, which represents 6 percent of all homes. And those homes generate 8.9 megawatts of power.
  • The City has set a goal that 20% of housing units in Downtown Westminster would be workforce housing, targeting families earning 80 percent of the Area Median Income.
  • Westminster's golf courses-Legacy Ridge and Walnut Creek are dedicated to environmental stewardship and sustainability. Both of our award-winning golf courses follow the sustainability principles set forth by the Audubon International program and GCSAA's Best Management Practices, taking a proactive environmental approach to make sure we keep the "green" in golf.
