The question of why their called "urban" or "city" stores goes to footprint. The Seattle Downtown Target is part of a 18 [[I think) story high rise, where Target has taken the bottom 4 floors and a 200 stall parking garage.

In general....and keep in mind the last time I was in Detroit was 1996.....in urban areas there isn't the footprint available to place a 150,000 sq. ft. store with parking, definately not in Seattle proper.
