Child welfare services in New York City are undergoing vast change. The New York City Administration for Children’s Services (ACS) is moving to a neighborhood-based service delivery system in which preventive service and foster boarding home providers will serve distinct community districts rather than broader geographic areas. For foster boarding home providers, this plan is a dramatic shift in practice, as these providers have historically served fami- lies from specific boroughs or, in some cases, from any neighborhood in New York City. This change is less wrenching for preventive service providers because the new ACS neighborhood- based services model builds on a long history of programs that have always served a specific geographic region, spanning anywhere from one to three contiguous community districts.
