"You said to have them incorporate their own city. This seems different?" Everyone in a polity (a town or region or nation or perhaps special district) should be free to vote for every candidate running for that polity. The polity should have no geographic sub-divisions. If, as was mentioned above, a neighborhood in Chicago has a special culture, then: its residents have their city concerns met when they participate in city elections, and they have their regional concerns met when they participate in regional elections, and they have their national concerns met when they participate in national elections. But if you decided that their culture was so special, and deserved so much special protection, that the above was not good enough, then my suggestion is that the neighborhood should incorporate as its own city. Instead of being a neighborhood in Chicago, it should be an independent city with its own elections. As I said, if you really wanted to rescue some unique neighborhood, my suggestion is that you do so directly, without trying to achieve the effect as the accidental side effect of an unrelated architectural decision.
