Biggest concern people in Alberta should have is what happened to Edmontons ice district. A lot was over promised and the area is riddled with drugs/homelessness
It just doesn't work unless there's a comprehensive social and development plan to address the underlying problems.
Just plunking a shiny (ugly) new arena in there with a handful of halfway vacant "$3M luxury condo" towers doesn't actually magically solve the fundamental problems.
You need to figure out how you're going to address the homelessness issues. You need to bring in housing that is actually "affordable" and will be lived in by people. When you generate more natural foot traffic by people actually living and existing in those spaces, it tends to at least push those problems out toward somewhere else. Ice district seemed intent on recouping all the costs with huge dollar luxury places that don't bring persistent population to the area. Especially if they're vacant and unsold, or sold but still vacant as a 3rd or 4th home for someone international.
Same thing has happened with Edmonton's LRT. They refuse to invest properly in expanding it to make it more useful...so it gets underutilized, and becomes a haven for all of the other unresolved underlying social problems in the city. Becomes a death spiral that feeds on itself and just gets worse and worse.
If they'd had all that public money that went into the Arena and luxury development, to spend on social housing, transition housing, recovery programs, etc...they'd have ended up with a far better result for the city. It's not like Katz couldn't have afforded to pull his own weight. But they never held him to task on it and now the whole thing is kind of a mess with businesses pulling out of the area all over the place because nobody wants to spend time, or feels safe there.
