> What you are looking for is city infrastructure with green scenery. That's possible but the price tag is going to be astronomical.

In a car-centric culture like what dominates in North America, maybe. I've been to a city or two, though, that accomplished the hat trick of high population density, low noise levels, and nice scenery. Brussels, for example.

I'm pretty sure the magic trick is to convince your citizens that public transportation doesn't have to just be a last resort for poor people.
