Yes, there are faults in the State of Louisiana and it doesn't have anything to do with politics or FEMA.
East Baton Rouge Parish, which includes the capital seat of Louisiana, is traversed by at least two faults: the Baton Rouge fault and Denham Springs-Scotlandville fault. These faults are known to be active but apparently do not produce earthquakes. They are known to be active due to the damage to structures near the fault areas over a period of time. Some examples are cracked roads, slabs and walls.
These East Baton Rouge Parish faults are recognizable on the surface as escarpments having distinctive topographic expression. An escarpment is a long, steep, fairly continuous slope which separates more gently sloping surfaces on either side. The most prominent area of escarpment of the Baton Rouge fault is easily accessible to us.
The coordinates above take you near a busy intersection in Baton Rouge. The incline near here is actually the escarpment along the Baton Rouge fault. If you look to the northwest and then to the southeast you can note the "scarp" and follow the fault line for some time in both directions.
One side of the scarp is distinctively higher in elevation than the other side. The Baton Rouge fault is a normal fault; therefore the rock "underneath" the fault has been pushed up by extension forces. While the other side of the fault is lower in elevation as you can see in the drawing below.
Geologists have actually borrowed old mining terms to refer to the two sides of a fault - footwall and hanging wall. The footwall refers to the plate "underneath" the fault line. The term hanging wall refers to the opposite plate. Note the drawings below:
