It will be nice to see something new in that area, period.
There already is a youth services centre on that corner so I guess they are just incorporating it. As well, there are already plenty of mentally ill/addicted individuals in the area. This will not change that, but rather hopefully bring a bit more organization to the chaos.
I used to live at Fraser and 10th, and then at Fraser and 15th, so I know the area pretty well.
