This city needs a grand fountain (sorry, Olympic Plaza doesn't cut it). Even Edmonton has two substantial water features with high powered jets (Legislature and City Hall). Calgary has the two baby ones in Central memorial park and a couple boring spray jets in Olympic Plaza. I don't count spray/splash parks or pads as they are rather small scaled. I hope during the Olympic Plaza redo they transform the fountain into something grand.
Victoria Park doesn't even have a park in it (EVP and SP don't count), if the city had any sense of planning they would incorporate some kind of plaza/park feature with the new arena. You know throw in a fountain or water feature that could be used as a hockey rink in the winter, maybe a couple statues of Calgary Flames greats like Lanny and Iggy, some retail and restaurants around It and a hotel in the nearby area. You have a nearby train station for people to come in on the Red Line and another future one coming on the green line. Put a Park in Victoria Park lol, it only makes sense.
Other potential candidates in no particular order include:
-Olympic Plaza redevelopment as you said...
-Eau Claire Market redevelopment, that area has lots of potential.
-Tomkins park? idk if its been redeveloped lately I can't remember
-West Village? why not just make it into a mega park, like Central Park? As much as we all hate I admit it nothings ever going to get built there so why no bulldoze the car dealership and abandoned Greyhound station, move bow trail away from the river and make a public space? The area has potential.
-James Short Park? Needs to be renamed why not throw in a redevelopment.
-Not to mention the ungodly amount of surface parking Downtown and in the Beltline, getting rid of one or two blocks of surface parking and turning it into a park won't hurt no-one.
Are there any other areas? I can't think of any
