re: Anywhere in New Orleans actualy in Jefferson Parish??

Elmwood/River Ridge/Harahan is a cluster Frick in that aspect. Many autofills online will put RRs 70123 zip as Nola for the city. (weird that its designated that as Gentilly is 70122 and not even close by) Elmwood and RR are patrolled by JPSO while Harahan, located sort of in between the two, has their own police department, Harahan PD. All the while Causeway PD works the Huey P. NOPD is nowhere out that way.

But in reference to the question in your OP, its the airport.
