To help with that initiative in the nation’s capital, a team at the University of the District of Columbia has created a rooftop garden on campus with a wide variety of vegetation to help absorb excess rainwater and grow food at the same time.

Architect David Bell, who designed five “green roofs” on the campus, says he’s excited about the project because “it meant doing something more than just dealing with storm water management.”

Rainwater is distributed through an irrigation system and collected in cisterns for the rooftop garden. It is also used in other parts of the campus.

The result is a picturesque sea of green vegetation and patches of brightly colored plants and flowers that attract pollinating insects and other wild creatures.

“In an urban environment, you don’t have that many spaces to choose from, and so rooftops are just unutilized space,” said Caitlin Arlotta, a graduate student in the University of the District of Columbia’s Urban Agriculture program. “So it’s a really good way to not have to restructure your city necessarily and be able to incorporate green roofs.”
