Fully agree with your point. I just feel like pointing out that, ironically, 17th Avenue SW has a 5.182m public realm setback on it, so this project will need to be pushed back from the current property line by 5.182m, to widen the ROW for 17th Avenue. You can see this in the DP drawings. I am being a bit tongue in cheek though, the City has at least started allowing these setbacks to be used for widened sidewalks, street furniture, trees, etc... But, this setback table has existed in the land use bylaw for decades, and for the longest time was meant to preserve land to allow for road widenings as you described.
I guess that is not really ironic, I just felt like pointing out this technical requirement on this project, as it relates to the above post.
