Because the University of Miami, with its 30,000 employees and students and $2.9 billion in annual revenue has no clout at all in Coral Gables.... a city with a total population of around 60,000.
This whole "Coral Gables would never allow it" narrative is ignorant as ****, to be honest. It's exactly what the BOT would want you to believe, and I suppose gullible people are going to lap it up.
Use common sense. UM is the biggest hitter in Coral Gables by far. If UM wants something done in that city it will get done.
