This document outlines a research project comparing the social construction of cultural heritage and leisure in the waterfront areas of Bilbao, Barcelona, and New York. The research has three objectives: 1) Analyzing emerging trends in the urbanization, experience, and management of public spaces in metropolitan waterfronts, 2) Mapping urban commons and innovative uses of public space through collaborative tools, and 3) Examining rights to leisure and how cities use culture and the arts to create and brand their images. The methodology includes discourse analysis, ethnographic mapping of spaces and their uses, and expert panels, interviews, and focus groups with practitioners, planners, artists, and citizens.
