As I've said for years, any time you see a glittering urban core full of glass towers, steel bridges, and classic old stone architecture, somewhere there's a Mordor nearby that made all that happen.
But to make sure that it doesn’t veer into city bashing (as HN is sometimes wont to do): the only difference between the glistening urban core and 300 square miles of suburban sprawl is the number of trucks needed to distribute the raw materials involved. All things being equal, the pollution involved in building the former is both lesser and more sustainable.
Boston area has no big chemical/hard industrial industry, and nothing on that map. Neither does seattle (but the map shows some small process in areaa). Id wager a lot of modern "intellectual" cities (where knowledge worker industries dominate) can be devoid of such processes. Tourism cities too - eg, Vegas and Miami don't have such a history and their maps are clean.
Obviously SFBay is a notable exception to the knowledge-worker idea, but SV was founded on horribly toxic silicon refining which, while mostly gone, has a terrible history of poisoning the ground.
