MitchE has created an extremely impressive photo thread of Portland's (mostly new) burban developments, and an interesting discussion has followed. I know Dougall mentioned this in another thread, but if you haven't checked it out, it is comforting to see that Metro's policies are leading to quality and dense suburban development. MitchE in one of his posts makes an interesting case that in 15 years or so, if these policies stay in place, many burban neighbohoods will be more dense than many inner Portland neighborhoods.
