No AFFECTS from flooding? Interesting you said all sorts of things related to Katrina changed for you.
Because you don't see the water doesn't mean flooding didn't happen. That would be like coming back to your house that burned and saying there wasn't a fire because you didn't see the flames.
The house where I lived has its flooring about two and a half feet above the street, and the street took (I'm told) two feet of water. So there was no damage to the house or what was in it. Matter of fact it got rented out to a friend whose house in another part of town was utterly destroyed.
So as far as that residence there was no flooding. Of course everybody had to seal up their refrigerator and leave it in the street to be hauled away without opening it up.
The after "affects" came from the fact that the city still had no facilities, no electricity, no gas, no water, barely any cell phone service, no internet, virtually no police or fire departments, no businesses open, no food, no trash pickup -- and my house was in the neighborhood of three restaurants that all used the same dumpster --- and entire areas were covered in black mold.
And that set of conditions also means-- no employment.
In other words I still had my place to live, if I could take the smell and could contrive ways to eat. But there was no way to make an income.
That's when I cleared out what I could and relocated to North Carolina.
