I think that happens everywhere. For example, Toronto, from Front Street (aptly named, since it was the waterfront once upon a time) to the actual waterfront, complete with all its skyrises and highways, is 100% landfill underneath. I'm guessing we've done it right though, because we haven't had random garbage "sprouting" as often happens in places that used to be literal dumps. There are old maps that show how the waterfront grew over the years to where it is now. Very interesting to look at.
