Waaaait a minute... that is not the Detroit School of the Arts... that is Cass Tech... one block west of these Apartments. The Detroit School of the Arts is 8 blocks north of here... closer to Woodward.
In this Google map... the site of old Cass Tech is still shown in the lower left, with new Cass Tech just above it. And just to the right of [[former) old Cass Tech are the apartment buildings in question...

How the hell can Ilitch put an arena on this site?? That's right he cannot! There is no friggin' way to fit an arena here with Cass Park just north of here.. and Cass & Clifford Ave's just due east of here. Both those streets are the western gateway from Downtown to Midtown, and I doubt very much that the city would entertain closing them [[at least not Cass).
So these apartments CANNOT be part of a footprint for the arena... just not possible. Part of the greater arena area... maybe... but not part of the actual footprint, since it's sort of sandwiched west of Cass.
