Though more than 4,000 Louisiana homeowners have received rebuilding money only in the last six months, or are struggling with inadequate grants or no money at all, FEMA is intent on taking away their trailers by the end of May. The deadline, which ends temporary housing before permanent housing has replaced it, has become a stark example of recovery programs that seem almost to be working against one another. Thousands of rental units have yet to be restored, and not a single one of 500 planned Katrina cottages" has been completed and occupied. The Road Home program for single-family homeowners, which has cost federal taxpayers $7.9 billion, has a new contractor who is struggling to review a host of appeals, and workers who assist the homeless are finding more elderly people squatting in abandoned buildings. Nonetheless, FEMA wants its trailers back, even though it plans to scrap or sell them for a fraction of what it paid for them. As of last week, there were two groups still in the agency's temporary housing program: more than 3,000 in trailers and nearly 80 who have been in hotels paid for by FEMA since last May, when it shut down group trailer sites. Most are elderly, disabled or both, including double amputees, diabetes patients, the mentally ill, people prone to seizures and others dependent on oxygen tanks. Of those in trailers, more than 2,000 are homeowners who fear that the progress they are making in rebuilding will come to a halt if their trailers are taken. Progress on renovations has been slow for many reasons: contractors who did shoddy work or simply absconded with money, baffling red tape and rule changes, and inadequate grants.
