I made a thing for y'all based on that old hex map of London. Use it at your leisure. Basically, the Citygrid boils down an urban area to its spacial relationships and disregards its physical outline. Maybe (probably) this won't work for unusual cities, but for a standard city things should work out fine. Not all of the outlying neighborhood hexes need to be utilized, and there could even be additional out-outlying neighborhoods in the outer ring.
