Atlanta's Sweet Auburn Historic District, where Martin Luther King Jr. was born and later preached, is on the list for the second time.
It was first listed in 1992 when the area around King's birth home was at risk. Since then, much of the area has been revitalized, but much of the commercial corridor remains vacant and could be wiped out by new development.
