The changes mentioned in the OP will happen with time. The reality is that most Calgarians don't consider those things "livable". They consider an SUV, Large yard, & 3000 Sq feet livable.
The things the OP desires (as do I) as desired of the minority in Calgary. For now, enjoy the pockets that you have, or move to Vancouver like I did.
Don't expect the city to change too fast when most don't want it to.
