BA...catagory 3's are commonplace...standard.
You dont just build 'em for the standard. N.O probs have been known for a long time.
Catagory 5's are fairly common and can hardly be called a "freak" storm. When an entire cities existence is at stake you dont just build and hope for the best.
I know beauracratic spin bullshit when I hear it.
More will come of this.
Okay, well, I still have questions.
Category five's are common???
So, then it wasn't built for Category 3???
What problems have been known for a long time about NO???
