Habitat for Humanity leaders say they plan to build thousands of homes along the Gulf Coast in what could be the Georgia-based organization's largest construction project ever. Habitat plans to launch "Operation Home Delivery" later this month in Jackson, Mississippi.
It will assemble housing frames there and put them on trucks bound for Alabama, Louisiana and Mississippi.
The nonprofit group has issued an emergency appeal for donations and volunteers.
Habitat officials say they've had an overwhelming response of online donations, with more than $450,000 pouring in during the four days after Katrina made landfall.
Habitat volunteers will build the housing frames around the country, then ship them to the Gulf Coast.
From there, up to 30 volunteers per house will do a "blitz build," allowing houses to be constructed in about a week.
