NO East was in the mouth of a surge funnel. So was St. Bernard Parish.
Look at the levee maps.
This was well known long before the storm.
I knew that! I lived in NO East in different places from 68-80. Got out there while they were building a lot of the wetlands into housing. We used to get chased by these huge mosquitos and it was a mile to the busline. My junior high was 20 miles away because they hadn't built a middle school out there yet.
When Camille blew up there was no way my daddy was going to stay there.
So we left, and it took four or five hours to get across NO.
