This report briefly describes the Marin City, California community and summarizes progress made by the Far West Laboratory's Western Regional Laboratory in the development of a long-range community intervention program. Marin City is a predominantly low-income, black community in which 30 percent of households, mainly those headed by single women, live below the poverty line. Local officials consider substance abuse in the community to be at crisis level. Economic opportunities are limited, and unemployment is chronic and high, especially for teenagers. This report describes technical assistance provided to the community, an ethnographic study of the community, training workshops, and long-range planning and networking with other communities. An appendix provides the planning paper for the Bay Area Early Intervention Program. (RH)
