I'm very pessimistic about this development because I think it's been all about maximizing revenue from the beginning. On the other hand, there are a few things that it is doing right. Yes Barclay Parade is pleasant as it bends around the Barley Mill, but it is awkwardly placed, since it creates a barrier between the public plaza to the west and the market to the east. The new public plaza will likely be more sterile than Barclay Parade, but it looks like it will have a better layout for hosting festivals like the Taste of Calgary.
And, as others have said, it will reconnect Riverfront Ave to 3 St, breaking up a mega-block, and adding residents and amenities to the downtown core.
