Hey man....I am coop member, so it not specific criticism of their intent. Its just that for the last several years, our senior city planners have been talking about their "plans" for 8th street as a RBT corridor with more density and mixed use; changing the nature of the builds (as you point out) to have commercial and residential closer to street with parking behind. For this to happen...ANY opportunity for redevelopment will need to conform to this vision and if it doesn't fit, then they need to look elsewhere in the city (i.e. suburbs).
I just find it disappointing that there are still no "teeth" to this great vision for 8th street, but who knows....maybe Fed Coop will build something spectacular to start the ball rolling!!
