Am finally catching up. Did you see this page with all the levee heights?

No, the media says they are 13 feet, but that was a figure before the subsequent settling, and they are vague about what the current figure is. Maybe your website has the current figures, about 10 feet it seems.
I'm supposed to travel to NO on 9/13 for a presentation.
I hope this thing hits at the Ala/Mississippi border.
