The Associated Press reports New Orleans officials have told the last remaining residents of the temporary housing units known as “FEMA trailers” to be out by the start of 2011. Residents told the reporter that meeting this deadline will be difficult. At one point, some 23,000 homes were in the city. Estimates conclude there are 106 FEMA trailers left in Mississippi. Across Louisiana, about 520 remain. The city is taking aim at the remaining units, an icon of Katrina.
