Part of how we can know how serious the church is about this— watch the sidewalk plans once the temple is done. If it is the round sidewalk, with a diagonal one jutting off toward the northwest? Then we know they are serious.
Honestly, this screams MEGABLOCK. This is Jordan Landing. Put it as a greenfield development someplace else? I really like it. But within the framework of the existing downtown? I don't like it at all. (One page literally says a top priority for guests is "A convenient parking space"!)
When NuSkin stole a city street in Provo, I was told it would make the city better. It didn't. When the church stole another street for the Provo City Center Temple, I was told the same lie. Downtown Provo kind of sucks south of Center because there is no 24/7 pedestrian access. It's a blood clot. Those blocks are DEAD.
Anything north of South Temple DIES with this plan.
Nobody will want to walk on State Street anymore than they want to walk underneath the convention center. The church will not provide a 24/7 easement on the other blocks.

The monorail (while insisting it must not feel like an amusement park) is a nice touch...
