Tufts’ Rain Garden represents the University’s ongoing commitment to Sustainability. Located between the Hogdon and Lewis Halls, the garden is designed as a Green Infrastructure project, absorbing stormwater runoff from the local area and filtering it cleanly into the groundwater table while also reducing the amount of water being sent to the city’s infrastructure. The rain garden is just one of Tufts’ many sustainable landscape features.
Permeable Pavement Installation
The Permeable Pavement installation is incorporated into the Miller Hall bicycle shelter on campus. As water drains through the porous asphalt, it is transferred to the underlying, open-graded stone bed beneath. The water then infiltrates slowly into the soil. The stone bed, often 18 to 36 inches deep, provides a sub base for the asphalt paving and must be designed so that the water level never rises into the asphalt.
Organic Turf Management Techniques
Turf is an ecosystem: a community of plants, microbes, insects, earthworms, and other organisms. The interactions among all these organisms determine the health and appearance of the turf. The goal of organic turf management is to understand and work successfully with all the elements of the ecosystem. The result is attractive, healthy turf that is easy to maintain.
The project currently involves just over 2 acres of campus: a southern area around residence halls and a children’s playground; a field used for informal sports by both college students and a community youth soccer league; and the varsity baseball diamond. These pilot areas were selected to provide experience with a variety of types of turf; the varsity baseball diamond, for example, is managed much more intensively than the informal sports field. All areas included in the project are receiving pro-active maintenance to ensure good turf quality, and are not being treated with any herbicides or other pesticides.
2009 update: weeds on the baseball fields were not acceptable to the athletic coach, and that field was converted back to conventional treatment. We are hoping that additional training might lead to some better techniques for future weed control.
Why Reduce Pesticide Use?
Pesticides are chemicals designed to kill living organisms, including microorganisms, insects, plants, and mammals. Herbicides, insecticides, fungicides and rodenticides are all examples of pesticides.
According to the U.S. EPA, “Pesticides can cause harm to humans, animals, or the environment because they are designed to kill or otherwise adversely affect living organisms.” Pesticides can irritate eyes and skin; damage the nervous system; act as endocrine (hormone) disrupters; disrupt immune function; affect the reproductive system; and cause cancer.1 Pesticide use can also disrupt ecosystems and harm non-target organisms.

Reducing the use of pesticides through alternative methods of pest control and turf management can significantly reduce threats to public health and the environment.
Pesticide Use at Tufts:
Tufts facilities monitors the grounds continually, and identifies problem areas which may require fertilizer. They use a spot treating technique for problem areas and always engage in sound horticultural practices. The grounds are seeded and fertilized regularly at rate of 4 pounds of Nitrogen per thousand square foot, per year, which is done by a licensed contractor. The most commonly used fertilizer at Tufts consists of methlene urea, or sulphur coated urea for a slower release. On the grounds we do three applications and only treat broadleaf weeds and crabgrass where we find them. The applications are done in accordance with IPM specifications. This occurs on approximately 20 acres of the grounds.

Grassroots Environmental Education: A nonprofit organization that provides information and training on pesticide hazards and options for organic turf management, including training courses for lawn care professionals.
