Woah, we've had some 'pack 'em in' zoning here in New Zealand but I've never seen anything where they left out footpaths entirely. Has anyone got a representative Google street view link for SW Portland or something similar? (And is this really quite common across the US?)
This is the American suburbia I know best. Falls Church VA. http://maps.google.com/maps?f=q&source=s_q&hl=en&... Portland is not a good example of American urban planning gone awry. As it's probably one of the most sensible cities in the US. And yes, unfortunately neighborhoods without sidewalks are all too common in American suburbs.
Mostly, but there's really 2 Portlands. Downtown & the eastside are dense, mostly flat, walkable and with excellent public transit. The west side is hilly, mostly suburban, and generally neither walking nor transit friendly.
