A brief summary of the institution’s approach to sustainable landscape management:
The Grounds Department uses drought-tolerant xeriscape plants in many campus landscape areas, while limiting grass to activity areas and sports fields. A centralized irrigation control computer provides efficient watering for the campus, and more than 95 percent of campus is irrigated with nonpotable, reclaimed water. The grounds department uses Integrated Pest Management methods and preventive plant care strategies to minimize pest problems with the landscape. When they must use pesticides, they use those that have the least toxic effect on the environment while still controlling the pest problems.
None
A brief description of how the institution protects and uses existing vegetation, uses native and ecologically appropriate plants, and controls and manages invasive species:
The Grounds Department uses drought-tolerant xeriscape plants in many campus landscape areas and tries to limit grass to activity areas and sports fields. Buildings surrounded by or adjacent to areas that have successfully incorporated native and ecologically appropriate plants include: Cutler Hall (native grass), Hulbert Center (native plant garden), Ticknor & Taylor, Morreale House, the Japanese Garden (bamboo and Japanese Maples), Bemis Hall, Cossitt Hall (native species and boulders from the foothill areas), Tutt Science, Shove Memorial Chappell (native sage),Palmer Hall (native grass), and Barnes Science (apache plume).
None
A brief description of the institution’s landscape materials management and waste minimization policies and practices:
Grass clippings and leaves are mulched and returned to the soil.
None
A brief description of the institution’s organic soils management practices:
To protect the natural nutrient cycle of soil on campus, the Grounds Department tills compost into annual and perennial beds and mulches leaves and grass for grassy quad areas.
None
A brief description of the institution’s use of environmentally preferable materials in landscaping and grounds management:
The College primarily sources its plants from Denver and its rocks and stones from other local sources.
None
A brief description of how the institution restores and/or maintains the integrity of the natural hydrology of the campus:
A centralized irrigation control computer provides efficient watering for the campus, and more than 95 percent of campus is irrigated with nonpotable, reclaimed water. Irrigation is dictated by information provided by an on-campus weather station installed in the fall of 2007 at Stewart Field. This station monitors humidity, rainfall, temperature, and wind speed. It also feeds evapotranspiration (ET) data to the irrigation computer, which sets an order and duration for watering in each zone accordingly. The irrigation crew monitors the effectiveness of the program, occasionally overriding the automated system if observation indicates over or under-watering.
None
A brief description of how the institution reduces the environmental impacts of snow and ice removal (if applicable):
The Colorado College Grounds Department uses a variety of salts for snow and ice removal. Ice Slicer™ Granular Ice Melt is applied to roadways. Ice Slicer is a mined mix of magnesium calcium, sodium, and potassium chlorides along with trace minerals. It is less costly and corrosive than other commonly used compounds, which are known to leach into and change the composition of soils and groundwater, it’s widely acknowledged as a more environmentally preferable option.
The use of less preferable options, such as liquid magnesium chloride, is minimal and is kept only to target areas, such as steps and ramps.
