Ask HN: Tons of new banks in my city. Why?

I live in Rochester, MN which is population ~110k.

There are TONS of new construction physical banks being built in town. A small town that is already saturated with existing bank storefronts. Why is this?

They are from many different financial institutions, so its not like one institution is growing.

Aren't most new banking clients going online? I can't wrap my head around the business case that would exist for a new bank storefront when there are already ton's of them in this small town.
