I don't know much about development, but it looks to me like they'll need some special use permits or zoning changes or something to go above four stories on 3 out 4 of the blocks (looks like only the existing office building block is RF-2, the rest are B-6 or R-63). Hopefully they'll want to go higher (if costar ends up being the buyer I think they would want to), so the neighborhood association might be able to bargain for a first-floor grocery store place as part of supporting that process.

I don't go to the Manchester Alliance meetings (I live in Blackwell, which is outside their zone), but people in old town manchester or industrial manchester could do so.
