On the top of my head, I cannot think of any mixed use city halls. I am wondering what is at that location now. Is this new building better than what is there now?

Also, 17 stories is a substantial building. I don't understand the concern for not having a taller building. It seems like there is plenty of space that can be developed and going taller isn't necessary. In fact, two 17 story buildings might be preferable to one 34 story building and an empty lot.
I agree with the concern about creating a pedestrian dead zone.

Sorry, I got off the topic of your original question. I would be very interested in hearing about mixed use city halls if they exist.
