That's according to the head of the Chicago Housing Authority.
The agency's plan seeks to move public housing residents out of high rises and into mixed-income developments.
CHA chief executive Terry Peterson says decreased federal funding and his decision to not relocate residents during the winter months contributed to the delay.
"I want to make sure we do it right. I don't want to just throw up some frame homes, because then you're not going to create mixed income communities. And then you'll be saying to me, 'Well, you threw up anything. You threw residents in them. Look at what we've got now.' We're going to do this right," Peterson says.
The Plan for Transformation was to be completed by 2010.
