Big Eraser: Topic and Goals

I'm researching changes in public housing in Decatur. I wanted to research this topic because I feel that tearing down the OP's (Original Projects) is like erasing a big part of Decatur's history. I am having friends taken away from me because they must move out of their apartments. I hope that through my research I can figure out a good reason for why they are tearing down the OP's.
