PERCIVAL, Iowa (AP) — A third bout of flooding is taking a toll on people who operate businesses along Highway 2 in southwestern Iowa. They rely on Interstate 29 traffic and on travelers being able to cross a nearby Missouri Bridge over to Nebraska. But roadways leading to their community were covered with water and the businesses were inundated in mid-March after levees failed. More flooding occurred in late May. One business owner, Alicia Chrastil, who also was flooded out in 2011, doesn’t see herself returning.
