I agree that parking decks at ground level are tacky. All you have to do is look at the ugly duckling that the Meridian Building built. If at ground level there were shops and services it would be fine.
Street level parking except on the streets themselves should be outlawed in the zone bounded by Gervais, Assembly, Elmwood, and Bull. In cases where the lots already exist require them to be hidden with a brick, stone, or other attractive masonry privacy wall.
Parking decks do NOT have to be ugly! With parking on top of retail then either office space or apartments on top of that can be done beautifully. That type of architecture is a mainstay in Chicago.
waccamatt, when I get my first $100,000,000.00 I will fulfill my daydream of taking one city square, put retail on the street level all the way around plus an arcade through the middle, put a ten level parking deck on top of that with a 20 story office building on one corner and a 20 story apartment building on the opposite corner. The top of the parking deck would not be parking but amenities for the apartments like a swimming pool, tennis/badmitten court, etc.
If we are going to dream, lets dream big! B)
