Good info, thanks for that. Surprised the StA trail option scored so low on land use, maybe I'm misunderstanding the intent, but it seems that row has the most tod infill potential?
I have a radical rethink for metro line though...
Since the university av crossing prevents running 2 lines south from there, why not turn metro line into a U shaped route, with the current leg veering east to 97st and running elevated north, and then use the StA trail row and 121st corridor, going underground north of 107av to jasper, veering east to join the existing tunnel.
The line would end up being more skytrain than streetcar, but given what future projects are likely to cost, we should be getting the better frequency a skytrain system can provide.
The fed money angle for this is if the 97st leg was extended north all the way to the garrison, the feds could file their contribution under 'improving base transportation' and might be willing to fund a larger portion of the build if they can consider those funds part of Canada's 2/5% NATO spend.
Might be a stretch, but it's money that could be spent quickly, while more lengthy defence procurement gets ramped up.
