Actually, the north side is pretty unused, actually not at all.
Theres barely ever cars over there, and that building that used to be the post office is just dead space, so it is possible on the north side.
As for the south side, the space that is unused which they are talking about is very small. I can't possibly see that many building being clustered together in that space.
The notice went on saying that they may also build a community centre in the area, for incentive porposes. I think they are trying to win over the residences, but from what I've heard, this proposal is facing a lot of opposition.
