Washington, DC, is also built on a swamp, which gave them a lot of trouble building the metrorail (the second-largest underground rail in the U.S. if I recall). Likewise the Green Line in Boston's T, serving the filled-in Back Bay, is always flooding.
What is it that makes people look at a mucky, smelly, bug-filled swamp and say, "this is a perfect place for thousands of people to live?"
Oh I see, kind of reminds me of Venice the city of canals. I gather that the whole city is on unstable ground and will just keep sinking. I'm not sure if they can protect Venice with dykes like they do with parts of Holland.
