How do urban spatial practices contribute to the formation of collective identities and action and to the hierarchical structures of a city’s varied communities? This paper examines this question by presenting a comparative case study of two East Oakland public spaces – the streets and parks of a residential neighborhood and the hybrid public spaces of the Eastmont Town Center. A comparative analysis of the implicit property relations and “publics” produced at each site shows that, despite their differences, these spaces and their attendant collectivities share the same fundamental logic and limits.
