Nice map. Prior, I used
this one. Scroll down to the pinkish one. The little high ground area along the lake, also has some chic neighborhoods (my brother has a friend that lives there; we checked it out last night; it went underwater too, because the water got to five feet above sea level, as the lake rose, but presumably not by more than about 3 or 4 feet or so). I don't think it is an accident that the money followed the elevations. Other than that island, the motto was to live between St. Charles Street and the river, and hope the river levees last as long as the Wall of China.
Which reminds us, that in a surge, the lake will rise, and if the winds are strong enough in a perfect storm, the surge will be another 5 or 10 feet, and nothing will be spared. Nothing. The motto is that if you live there, and the weather Gods get ugly, you need to leave. Period.
