ngs of urbanist Jane Jacobs, Dr. Mindy Thompson Fullilove reveals the disturbing effects of decades of insensitive urban renewal projects on communities of color. For those whose homes and neighborhoods were bulldozed, the urban modernization projects that swept America starting in 1949 were nothing short of an assault. Vibrant city blocks?places rich in culture?were torn apart by freeways and other invasive development, devastating the lives of poor residents. Fullilove passionately describes the profound traumatic stress?the "root shock"?that results when a neighborhood is demolished. She estimates that federal and state urban renewal programs, spearheaded by business and real estate interests, destroyed 1,600 African American districts in cities across the United States. But urban renewal didn't just disrupt black communities: it ruined their economic health and social cohesion, stripping displaced residents of their sense of place as well. It also left big gashes in the centers of cities that are only now slowly being repaired. Focusing on the Hill District of Pittsburgh, the Central Ward in Newark, and the small Virginia city of Roanoke, Dr. Fullilove argues powerfully against policies of displacement. Understanding the damage caused by root shock is crucial to coping with its human toll and helping cities become whole.
