Castle Rock Project Green

Our environmental commitment


Reducing consumption of resources has positive impacts on the local environment.

In 2008, Town Council inspired staff to volunteer their time to build a more sustainable Castle Rock to benefit Town residents and our unique and beautiful region. Town staff created an environmental sustainability program called Project Green. The broadly focused program includes energy and water conservation, solid-waste recycling and other areas to help sustain the natural environment and be responsible stewards of the Town's resources.

Air quality


Reducing emissions


We are reducing emissions from Town vehicles by increasing our inventory of hybrid vehicles. Each vehicle saves more than $2,000 a year in fuel and reduces the Town’s greenhouse gas emissions by more than 8,000 pounds per year. The Town also has increased its use of E-85 ethanol fuel. 

Reducing vehicle wait times


Traffic lights around Town have been timed to reduce vehicle wait times at intersections. Reducing idle times saves gas money and reduces greenhouse gas emissions.

Development and building


Building codes


Among the Town’s building codes is the 2006 International Energy Conservation Code.

Endangered species


Parts of Town are home to an endangered species, the Preble's meadow jumping mouse. A habitat conservation plan for this species also preserved habitats for other native animals such as waterfowl, beavers, foxes and deer while providing residents with beautiful hiking and biking pathways along the East Plum Creek. 

Open spaces


For wildlife conservation and human recreation, the Town of Castle Rock and Douglas County have preserved hundreds of acres of land as open spaces.

Energy-efficient lighting in Castle Rock


Many traffic signals in Town have been converted to LED lights, which not only save money but also reduce the amount of coal necessary to produce the electricity. 

Energy-efficient compact fluorescent lighting is being installed in Town buildings on an ongoing basis as lights burn out. Each compact fluorescent light bulb reduces electricity consumption by 70-80 percent.

Water conservation


Red Hawk Ridge Golf Course and Town parks have sophisticated irrigation systems with weather stations that water only as much as is called for by real-time weather conditions. 

Water conservation classes


The Town provides free Water Wiser classes to teach residents how to more efficiently water. 

The Town provides classes to instruct property owners and residents on the principles of xeric landscaping and teaches xeric options for perennials, annuals, trees, shrubs and grasses.

Long-term water master plan


The Town is working to ensure water for our future through the long-term water master plan.

Flooding and water control management


To prevent flooding and control water management, extensive stormwater systems have been installed and are monitored to protect water quality and personal property.on

Other efforts


  • The Recreation Guide and other Town publications are printed with soy-based inks on recycled paper.
  • The Police Department recycles its bullet casings and bulletproof vests.
  • Firefighter bunker gear is kept as a spare rather being replaced every three years.
  • The Parks Department collects branches and leaves during cleanups and reuses them to stabilize slopes and prevent water runoff.
  • The Town implemented a “Turn it off, Add it Up” program to remind employees to turn off the lights of rooms they are not using to reduce electricity use in the buildings. The Town also implemented energy saving standards for heating and air-conditioning in Town Facilities. During the heating and cooling seasons, thermostats are adjusted to reduce energy consumption round the clock.
  • Town staff members recycle, paper, glass, aluminum, batteries, cardboard, cell phones, plastic, printer and copier toner cartridges and tires.
  • In an effort to reduce the effects of chemical fertilizers on the local water resources, golf courses and parks around Town have use organic fertilizer and compost to nurture lawns and landscapes.

Awards
