Two types of residential towers hold the edge of each distinct neighborhood, or cell. These vary in height and are connected by “bridge” buildings that contain public facilities, additional residential space, and recreation programs on the roofs. Each cell has planned a distinctive green interior that contains walking paths, managed lawns, rain gardens, and natural areas that support and reinforce the ground floor design of the neighborhood buildings and facilitate the interaction between residents and nature. The surrounding constructed and natural wetlands provide ecological functions including natural storm water management and wastewater treatment. The north site is designed to contain almost completely residential buildings, so much of the green and ecological features support family living and community life.
