In a showcase project, the U.S. EPA demonstrates that in fact, it is easy being green.

The Ariel Rios South Courtyard project—located next to the EPAheadquarters in Washington, D.C.—is an 8600-square-foot development that showcases numerous green infrastructure techniques and low-impact development practices. Site features include rain gardens, pervious concrete, sustainable landscaping, an 1128-gallon cistern, and a high-efficiency irrigation system.
