Find out what the City is doing to include sustainable practices in its day-to-day operations and help achieve the goals of the Louisville Sustainability Action Plan.

Climate & Energy 

  • On July 5, 2017, Louisville's City Council advanced its commitment to a healthy and sustainable community by voting to adopt Resolution 34-2017 in support of the Paris Climate Agreement.
  • Solar for City FacilitiesThe City currently has 1,045 kilowatts of solar PV generating electricity with an additional 1,000 kilowatts scheduled to come online in the near future for a combined total of 2,045 kilowatts or 2 megawatts. Once completed the estimated annual electrical generation from solar PV will be 3.8 megawatt hours, which represents more than 50% of the annual electrical consumption for City facilities!
  • Energy EfficiencyWorking with Partners in Energy, Louisville’s 2017 Energy Action Plan targets a 2.5% reduction in our entire community’s energy carbon footprint in the first year, cumulating in an 11% reduction by 2030. We are exploring ways to reduce this even more.
  • LED StreetlightsNearly all streetlights have been replaced with LEDs in partnership with Xcel Energy, along with a large portion of streetlamps, with plans to replace many more.
  • Greenhouse Gas (GHG) Emissions Tracking - Louisville is working with Boulder County to update its 2014 Greenhouse Gas Emissions Study for the year 2016.
  • Sustainable Buildings - When constructing or renovating municipal facilities, the City considers sustainable practices (i.e. solar, geo thermal, etc.) and is currently designing the new Recreation Center addition to meet a LEED Gold standard.


  • 15-IZIP_E3Path+_Horizontal_RidingE-bikes - In 2017 the City approved the use of Class 1 and Class 2 electrical assisted bikes (e-bikes) on all streets and trails. E-bikes are a great way to get more people on bikes and to ride more often and to more distant locations. As an alternative form of transportation, the use of e-bikes helps to lower carbon emissions. Visit here to learn about Boulder County deals on e-bikes before September 30, 2017.
  • Electric Vehicle / EV Station - The City has invested funding in an electric vehicle for its fleet and has provided a Level 2 dual port EVSE charging station at the Louisville Public Library. 
  • Walking / Cycling - Louisville has 32 miles of contiguous bicycle trails throughout the city. We are also very proud of our walkable downtown with a Walk Score of 82!
  • US 36 Bus Rapid Transit system - The City collaborated on this to provide Louisville Residents a highly efficient alternative to driving along the 36 corridor. The US 36 bikeway provides a biking alternative for commuters as well as a great recreation opportunity. 
  • Cyclist / Pedestrian Infrastructure Improvements:
    • “First and Final Mile” Study - The city participated in this regional study and have begun to implement recommendations of the study by installing secure bike lockers on both sides of the McCaslin BRT stop.  
    • Improvement to bike lanes are made as we repave major roadways.
    • New Underpass: In addition to our existing underpasses we are completing the South Street Gateway, and are planning a new one in 2018 under highway 42 at North End. In 2019, another underpass is planned under the BNSF tracks at Steel Ranch. 
  • Open Space and Park Trails allow people to get around town in a great natural setting. 

Waste Management 

  • Green Purchasing - The City is committed to purchasing green products for special events. The City currently purchases biodegradable plates, napkins, utensils, and recyclable cups. It requires vendors to do the same for certain events.
  • Recycling / Composting - The City implemented a residential “pay-as-you-throw” priced recycling and composting program in 2009, which, along with yard waste collection, diverts ~50% of Louisville’s waste stream from the landfill.


  • A new, more efficient Waste Water Treatment plant (supported in part by a state grant) has been completed. This allows us to meet more rigorous standards in water treatment, reducing contaminants into Coal Creek.  The new plant uses more efficient pumps and blowers as well, reducing its energy use.  
  • Water Supply Plan - The City is evaluating climate change impacts on the City’s water supply and adopting a long range water supply plan that recognizes and reflects the impact of climate change.
  • Water Storage Rights include Louisville Reservoir, Harper Lake, Marshall Lake, the CBT reservoirs, and we are adding storage capacity by participating in the new Chimney Hollow Reservoir west of Carter Lake. 
  • Reuse Water is used to irrigate the Coal Creek Golf Course, the Louisville Sports Complex, Miners Field and Dutch Creek Park. 
  • Facilities water usage is being benchmarked and plumbing upgrades are in process of being implemented in city buildings.  

 Local Food & Agriculture

  • The City partnered to develop a Community Garden in 2015.  This is in addition to the garden already in place by the Sports Complex.
  • The Harney Lastoka Open Space is scheduled to be a Community Supported Agriculture farm in the next year or two, where you’ll be able to buy more organic food grown on the farm.  
  • The City of Louisville approved the raising of a small number of chickens in people’s back yards so they can have access to freshly lain eggs.
  • The City is working to control and eliminate noxious weeks on open space lands with reduced use of herbicides, and greater use of alternative methods, such as the goat herds used at Harper Lake and on Davidson Mesa.
