I haven't seen many buildings for here in the Pacific NW, except for Lehigh Cement, the Steel Bridge, Bridge of the Gods and a couple of Portland buildings (apartment buildings and a handful of low poly offerings from dmdrake). Also found a Wal-Mart based on the one in Troutdale OR.
However, the above creator, dmdrake, does have several city blocks and city splines from New York, Boston, Baltimore, San Fran, etc. that work nicely to give that urban feel without spending hours doing so.
Also, I have downloaded a LOT of Australian buildings that were no different than those found here, such as shops (many of which are renameable) and the big name stores like Sears, Wal-Mart, Petco, McDonalds, KFC, Taco Bell, etc.
