last thing about legibility
I'm surprised no one has mentioned irvine in the discussion of legibility. It's a place that's "master planned" by the Irvine Company. Even the University is designed with a manipulation of legibility. Like professors never need to cross where the grad students live to get to where they need to get. From my apartment building (graduate housing) I can see Vista Del Campo. It's about a block away, but in order to get there I have to go down the street, cross over, and then back up. All this is intended to ghettoize the different *groups* of people. Also, once you are within University Hills or Palo Verde, there is a very legible navigation within the enclave, but you never get into that enclave unless you belong to the group.
