This article has a map: http://www.freep.com/article/20131018/BUSINESS06/310180105
I grabbed that address and plugged it into Google Maps, so the pin here is the northern corner: https://www.google.com/maps/preview#!q=Mack+%26+St.+Jean%2C+...
Edit: and according to Google Maps, "Indian Village" (home of the developer) is literally the southwestern edge of the area.
PS: I know nothing about Detroit, this is all just looking at a map.
