New York City

via NYTimes:
Five developers are competing to buy the development rights over the Metropolitan Transportation Authority railyards that straddle 11th Avenue, between 30th and 33rd Streets. They have submitted billion-dollar offers and elaborate development plans for what would be the largest project in Manhattan, on 26 acres stretching across the equivalent of six city blocks overlooking the Hudson River.
