For decades, traumatic experiences have been endemic in public housing communities such as the Potrero Terrace and Annex (PTA) in the Potrero Hill neighborhood of San Francisco, Calif. Such units were rife with community violence, concentrated poverty, structural racism, depravation and isolation. In 2011, San Francisco started HOPE SF, the nation’s first large-scale public housing revitalization project to tackle these monumental issues. A new community-building approach evolved as resident trauma and chronic stress made it tough to implement traditional redevelopment strategies. This new approach acknowledged chronic health and safety issues and became known as the Trauma Informed Community Building (TICB) model.

This evaluation examines the TICB model and its implementation in the PTA public housing community and informs efforts to implement the model in other communities. The report is synthesized in a TICB infographic.
