Bernice Mosely is 82 and lives alone in New Orleans in a shotgun double. On August 29, 2005, as Katrina hit the Gulf Coast, the levees constructed by the U.S. Corps of Engineers failed in five places and New Orleans filled with water. One year ago Ms. Mosely was on the second floor of her neighborhood church. Days later, she was helicoptered out. She was so dehydrated she spent eight days in a hospital. Her next door neighbor, 89 years old, stayed behind to care for his dog. He drowned in the eight feet of floodwaters that covered their neighborhood. Ms. Mosely now lives in her half-gutted house. She has no stove, no refrigerator, and no air-conditioning. The bottom half of her walls have been stripped of sheetrock and are bare wooden slats from the floor halfway up the wall.
