The only problem is that the land use part of that project explicitly focused on the retail district only here -

I don't know much about zoning but the changes seem really logical to me. Only problem is they didn't go far enough outside the very narrow focus area. The result is the mish-mash of spot-zoning and one-off land uses to the east. That may not be too big of a problem in itself - but would have been nice to consider the corridor consistently from the land use side so it's not a peace-by-peace redesignations process. In theory, that should minimize some of the inconsistency in redevelopment.
Compared to the Main Street changes along 17th Avenue from Westbrook to Crowchild - way more consistent and thinks full-corridor regarding land uses.

Will it matter in the end? Maybe not - lack of consistent land uses don't seem to be holding back these Sarina projects and better zoning =/= guaranteed better development. I think in Marda Loop / 33rd case it does seem to have played a role so far in how development is proceeding
