10+ years is probably heavily undershooting it. In the thirty years before The Parks was erected, this section of downtown from 105-109 and north of Jasper saw what, Monaco 1 & 2 be built? And if you go above 103 ave, I guess you can count Quest and Jefferson Lofts+whatever Dub resi conversions from the 90s. Thirty years to get ~5 residential projects and that included the 00s condo boom.
Reality is not enough people want to live downtown, and even fewer want to pay a premium to do so. I wish we could get better quality designs and height as well, but man the value proposition for downtown living just isn't there. Endless forever construction everywhere, few amenities beyond overpriced coffee and restaurants, terrible retail options, borderline zero nightlife, social disorder and continued rampant open drug use, and there aren't even that many good jobs here either unless you want to work in gov't or brokerage.
