I do think the wide streets and large blocks make it more challenging to feel urban. But I also think, as I said in my post, that the rapid deurbanization of Salt Lake once you're off Main Street and State Street plays a significant role in it.
It just doesn't feel like an actual major downtown outside State and Main.
You go down to 300 South and West Temple and there's nothing urban there. That might as well be a picture from Albuquerque, New Mexico:
Granted, there's room for that to change - and I am sure in 20 years it'll look very different than it does now. But these intersections just a block from the major core are devoid of any urban elements. Even 200 South still feels pretty mid, despite all the changes there.
Most major cities aren't going to see that dramatic of a drop-off just a block from its urban core. It just doesn't happen. Even sunbelt cities are built up better outside its literal center than Salt Lake is.
Granted, that's also just one example. We know the western part of downtown is still struggling (and boy if the Jazz relocate out of there and the Delta Center is raised, it'll be even more of a struggle).
It's better on the eastern end of downtown but I've concluded that wide streets and large blocks makes any area without significant height just feel less urban in nature.
So, you have situations like this where the urban-ness of the city just falls off even when it's still fairly urban:
Again, that could be any mid-sized US city. Hopefully we start to see further development that goes up - as I think that's really the only way to create that vibe with how wide our streets are.
