A U.S. flag dips into rising flood waters in downtown Cedar Rapids, Iowa, in this June 13, 2008 file photo. Thousands of flood-damaged homes lie vacant in the core of Cedar Rapids, a city of 120,000 hard hit by June 2008 flooding that inundated towns and farms across the Midwestern United States. Cedar Rapids' struggles echo recovery efforts in New Orleans and the Gulf Coast, flooded after Hurricane Katrina nearly four years ago, and in Galveston, Texas, following Hurricane Ike in September.
