Regarding municipal consent, there is absolutely no way a majority of the SLP City Council votes for any freight re-route. The damage has been done (by the flawed process) and in that community's eyes there are viable alternatives on the table.
Yep, and Minneapolis is going to say exactly the same, along with "routing through SLP is now cheaper!"
All this study did is make coming to an agreement more difficult.
I see the choice this way. On one hand, we have a less expensive option through SLP (assuming property acquisition is not too costly) that comes at the cost of some houses and businesses. On the other hand, we have a more expensive option that involves digging tunnels but doesn't require any takings. It's ~$50 million to preserve the SLP houses and businesses and avoid more freight near the schools, etc. There are human factors on both sides (losing houses, extra noise, etc.).
I was actually clearer on my choice before this study. Now I think it is a much more complicated decision.
