Re the TOD - Busy getting ready for Canada, so I haven't read all the posts. Perhaps it's been mentioned already, but the incomparable Jane Jacobs' THE DEATH AND LIFE OF GREAT AMERICAN CITIES is essential reading on the subject.
(I used to see Ms. Jacobs striding down the streets of Toronto. Always wanted to stop her and talk, but never did, alas.)
