Chicago's plans for Northerly Island‎

http://featuresblogs.chicagotribune....-thursday.html

"the plans "include stripping the old terminal building of its walls,
transforming the internal structure into an open-air pavilion. The
area would also include an underwater paradise for fish, plants and
birds and an eco-friendly concert venue near the Adler Planetarium."

"A harbor for aquatic wildlife would be on the peninsula's east side —
opposite the boat harbor on the west side. Rock formations would be
built underwater to attract plants, fish and birds.

"And architects will unveil a permanent design plan for the temporary
7,500-seat Charter One Pavilion venue, including a 'green' roof."
