Facilities and Grounds

New buildings are created to be sustainable and historical buildings are updated to save electricity and gas.

Physical Plant staff work diligently to make the campus clean and welcoming, while also embodying the natural beauty of the area. Many things go on behind the scenes to promote sustainability here on campus.

Building Certifications

Green Cleaning

Hope's Green Cleaning Policy is intended to reduce the exposure of building occupants and maintenance personnel to potentially hazardous chemical, biological and particulate contaminants, which adversely affect air quality, human health, building finishes, building systems and the environment.

Nature Preserve

The 91自拍论坛 Nature Preserve is a beautiful, 55-acre Beech-Maple forest approximately five miles from our main campus and 1/4 mile from the Lake Michigan shoreline in Laketown Township, Allegan County.  

The preserve is invaluable to ecological research and teaching in the biology department at 91自拍论坛. Find more information on the Department of Biology website.  

Campus Tree Brochure

91自拍论坛 prides itself in a beautiful campus environment that encourages the community to connect with nature. One of the most valuable assets to encourage this relationship is our trees, some of which we outline in this Campus Tree Stops brochure.

Grounds

Planting Bed Management

• Planting beds enhance the beauty of the grounds
• Buy bedding plants from local growers using site-specific plants and shrubs
• Use perennials and grasses that need reduced care and water
• Mulch with native hardwood bark
• Subsurface and drip irrigation

Turf and Soil Management

• Do not bag clippings from mowing
• Use spot spraying for weeds (as opposed to total coverage spraying)
• Mulch 100% of leaves into the turf and only remove leaves when necessary
• There is a reduced mowing frequency on lower priority sites
• Use integrated pest management practices
• A lot of mowing equipment uses alternative fuel sources (biodiesel and electric)
• Use grass seed instead of new sod where practical in new or bare areas
• Collect cultural care waste from pruning and bed clean up for composting
• Compost grass clippings from the athletic fields on site
• Purchase locally composted soil, take soil tests twice a year, use organic fertilizers when possible and use organic pest control products
• Uses water management software and monitoring systems for irrigation and employs a full time irrigation technician
• Worked with the Holland Board of Public Works (HPBW) to install a gray water line for use in our core campus to reduce the filtration level for irrigation

Tree Management

• 91自拍论坛 has been recognized multiple years as a "" by the Arbor Day Foundation.
• Replaces trees through purchase and contract growing with local tree farmers.
• Use water bags for the first year and during high-stress times.
• Installs bubbler zones for new plantings and removes them when plants are established.
• Use structural pruning, site-specific plant placement, trees that produce feed stock for birds and provide cover for nesting birds, spacing that provides for future natural development of the tree鈥檚 full size potential, placement that allows for a building鈥檚 shading or sun exposure, and planting native and zone-hardy species.
• Supports campus and local community environmental awareness education activities through tree planting ceremonies on Earth Day and Arbor Day.
• Learn more about our campus tree conservation practices and activities

Grounds Equipment

• Increasing inventory of electric hand mowers
• Diesel grounds equipment uses biodiesel produced from waste vegetable oil generated from dining services, part of a student project designed to reuse the 22,000 pounds of waste vegetable oil produced annually at the college
• Recharge electric mower batteries with a
• Maintenance rinses (grass clippings) from grounds equipment is captured and collected by a waste hauler for disposal.
• Athletic field paint machine debris is collected and filtered
• Full-time mechanic maintains all equipment and sharpens mower blades twice a week
• Waste oil is collected for recycling
• Replacing gasoline equipment with diesel-powered equipment
• Leases a front-end loader for more efficient snow removal
• Plow vehicles use effective snow plow blades and snow brushes to reduce salt use on sidewalks

Transportation

Biking

• 91自拍论坛 supports the use of bicycles (one of the most efficient forms of travel) by students, faculty, staff and visitors from the Holland community for traveling to and around our college campus
• In 2016 Hope installed a bicycle aid station to help keep campus and area riders rolling

• Maintains vehicles to maximize operational efficiency
• Shuttle service uses a minivan on its route around campus; its former serves the CASA program by transporting elementary students to and from campus
• Encourages carpooling through a ride exchange program for students on inHope
• Reorganized off-campus ride system to be a paratransit system in which rides are scheduled to minimize total mileage by combining rides to and from locations near each other

Public Transporation

• For short trips in Holland, Hope recommends using the
• For longer trips, Hope recommends riding

City of Holland 鈥� Downtown Snowmelt System

Since 1988, residents and visitors have enjoyed snow-free streets and sidewalks in downtown Holland throughout the winter season. Thanks to the Holland BPW snowmelt system, waste heat from power generation is captured to heat water, which is circulated through 190 miles of tubing laid underneath the pavement and sidewalks, back to the Holland BPW power plant. The system pumps over 4,700 gallons of water per minute at 95-degrees and can melt about one inch of snow per hour at 20 degrees Fahrenheit with winds of 10 mph.  The snowmelt system is a closed system meaning it is circulating the same water over and over again. To see maps that outline where the system runs and to learn more visit the .

91自拍论坛 Snowmelt Systems

Similar to the City of Holland a number of buildings on campus utilize a snowmelt system beneath their sidewalk entries. These systems utilize waste heat to warm the sidewalks and it allows for reduced environmental impacts from salt and decreases slipping hazards. This includes the Richard and Helen DeVos Fieldhouse, the Kruizenga Arts Museum, the Jack H. Miller Center for the Musical Arts, Cook Hall, the Jim and Martie Bultman Student Center and the Campus Ministries van Andel Huys der Hope.
