Editor's note: This article was published on May 23, 2005, exactly 100 days before New Orleans' levees were overpowered on Tuesday.
Standing atop the levee that protects Metairie, Louisiana, a satellite of New Orleans, from Lake Pontchartrain to the north, everything seems normal at first. But scanning your eyes across the horizon -- as I did last November, when I visited my hometown for Thanksgiving -- you suddenly glimpse the city's startling vulnerability. It's simply a question of elevation: On one side of the levee, the lake's water level comes up much higher than the foundations and baseboards of the nearby homes on the other side. Only the most expensive houses, those sporting third-story crow's nests, have rooftops that clear the levee's height.
