Where was the setting in the book iggies house by judy blume?

The main plot is that her friend (Iggie) moves away from her old house (Iggies house) and new black people move in and those were the only people that were black on Grove street. Mrs. Landon signs a petition to get them out and blah blah blah then winnie becomes best friends with the garbers and they end up staying and the landons move out
