The Birmingham News reports that the Federal Emergency Management Agency (FEMA) has approved nearly 250 FEMA manufactured homes for refugees of last month’s tornadoes in Alabama, but so far only 35 are occupied.  Before a home can be sited, officials have to make certain the space is suitable, and that water, power and sewage are correctly connected.  In addition, FEMA’s guidelines for positioning and anchoring the home are often more stringent than the state’s, and some people have had to wait longer in order to correct improper installations.  The Alabama  manufactured Housing Commission employs only certified contractors to do the installations, but given the scope of the work to be done, Don Griffin of FEMA says there is always a learning curve.  The effort in setting up the homes leads FEMA to try and find available rental housing first.
