Still could happen at that site! Imagine this -- a farmers market combined with an aquaponics and experimental vertical plant farm combined with a roof-garden parklet that tiers down onto the "Market Square" pictured in the plan which could be designed as food truck and event space centered on Agriculture (a kind of central Alberta Food Crop Agricultural Showcase). The basement of the structure could house extensive commercial fish tanks of various species -- Tilapia, Catfish, Carp, Largemouth bass, Trout, Perch, Barramundi, Sunfish, Crappie, Pacu, Bluegill, Guppies, and Eel. Then there are qualifying crustaceans that could be added to the mix including freshwater Prawns, Crayfish, Mussels, Oysters, and Lobsters.
A portion of the basement could be public-oriented with a display of "pet" specimens in bespoke designer tanks, fish like Koi, Goldfish (there are many exotic species that have been cultured for show and competition in these two types specifically) and others including domestic aquarium species like Angelfish, Tetras, and Danios -- a centerpiece could be a through-the(multiple)-floor waterfall that empties into a Koi pond (glass domed roof) visually tying all floors together.
The pathway accessing Market stalls could be ramped from entrance to uppermost floor with stalls demised off the ramps. Another feature could be glass-domed exterior stalls. The roof garden could similarly tier down the wall facing the Market Square with vertical plant walls (local species) festooned on exterior walls.
How could this come about? There could be a non-profit Cooperative Ownership set in place with long-standing Farmers Market practitioners as shareholders. This organization could then help in petitioning the Local, Provincial, and Federal Governments for supportive funding by way of grants and low-interest loans.
It is doable!
