Total campus area:

Figures required to calculate the total area of managed grounds:
Area (double-counting is not allowed)
Area managed organically, without the use of inorganic fertilizers and chemical pesticides, fungicides and herbicides 1.50 Hectares
Area managed in accordance with an Integrated Pest Management (IPM) program that uses selected chemicals only when needed 38.54 Hectares
Area managed using conventional, chemical-based landscape management practices 0 Hectares
Total area of managed grounds 40.04 Hectares

A brief description of any land excluded from the area of managed grounds:

Colorado College does not have any unmanaged or unmaintained land because it is an inner-city school.

Percentage of grounds managed organically:

A brief description of the organic landscape management program:

Neem oil and other organically certified products are used to aid in pest repellent. Marigolds were also planted in beds to aid in pest control. To address problems with deer, egg whites, garlic, and cayenne pepper were used. Mostly organic seeds are ordered but organic hybridized seeds may be used in order to serve as much of our community as possible.

Colorado College also adds compost in various gardens every 3-4 years.

Percentage of grounds managed in accordance with an IPM program:

A brief description of the institution's approach to plant stewardship:

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), Cascade and Nevada medians, and Barnes Science (apache plume).

A brief description of the institution's approach to hydrology and water use:

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.

A brief description of the institution's approach to landscape materials management and waste minimization:

Grass clippings and leaves are mulched and returned to the soil. Weeds and small branches are sent to Bestway to be turned into mulch.

A brief description of the institution's approach to energy-efficient landscape design:

Colorado College tries to be efficient as possible with new landscape design on campus. The Outdoor Education landscape was designed with xeric plant material and water saving irrigation products. It has an area for edible plants and compost containers. All the new gardens have drip systems.

A brief description of other sustainable landscape management practices employed by the institution:

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.
