NOLA with a twist

Fifteen years ago a series of storms hit the New Orleans area, the city was under water, the area declared unfit to recover.
A year after that, an anonymous person bought the entire area from the government of the united states. It didn't take her long to get rid of the water, and save what she wished saved. (She's a goddess).
Once the area was ready, the city itself began calling to those it wished to reside there, supernaturals, petranatueals, and in some cases humans felt the pull to go to Nola and settle. After enough had come, the city was open again to tourists.
The quarter is very similar to the real world, except no cars may enter, delivery trucks are allowed but only via certain routes, and on a strict schedule. It is considered neutral grounds (even if most who live there will tell you its cat territory) , no disputes in front of the tourists.
The CBD has changed, gone are most of the newer buildings. It is mostly used for tourist lodging.
Because this is modern day, you can use current events. Keep in mind Nola (and the area around it) is no longer a part of the US. It is a country of its own, a haven for any number of creatures that now wouldn't want to live anywhere else.
