Annapolis intends to test a floating island in a local lagoon that, if successful, could help clean the water in the Chesapeake Bay, according to Mayor Ellen O. Moyer……
Floating islands are created from recycled plastics and planted with wetland plants that soak up nutrients from the water, said Steve Carr, the city’s environmental adviser. He said the project in Annapolis will act as a test to see whether the technology can be implemented in larger areas of the bay.

Ken Belson of the New York Times has written an interesting piece about green walls which looks at the green wall as a source of food production. Belson talks to a varied number of designers, universities and manufacturers about the green walls as food production. He also states that at $500 a panel they aren’t for everyone.
Belson has a great quote he cites from Paul Mankiewicz, the executive director of the Gaia Institute in New York.

Bruce Hemstock, of PWL Partnership, a Vancouver landscape architecture and consulting firm that worked on the project, said the roof portion of the job was one of the most technically challenging assignments his firm has taken on in its 35 years in the business.
