"wonder if they've revised the sea level for Houston since I was in school several decades ago. Back then they taught us Houston was 6-10 feet below sea level"
If Houston were below sea level, it would need the same type levee system that NO has. Houston is very close to sea level but not below it
I have an uncle that lives 6-10 feet below flood stage of one of the rivers near Houston. There is a levee system on that river..
