I could not remember the name so I looked it up also and there are indeed several that popped up in a simple search.
I was peripherally involved in the one I list here (not sure how to make link work):
https://ecodistricts.org/registered-districts/towerside-innovation-district/
I list this web address for the simple reason that it is also registered with EcoDistricts, which I believe is an underutilized protocol.
Towerside is located in St Paul, MN
