Austin (tx) ville modèle, ville modelée : la (r)évolution de la culture de l'aménagement urbain dans une ville créative en plein essor

Abstract : The urban planning field strongly structures the Texas capital’s local political life. The actors confront each others on planning issues, ranging from the simple zoning case to the more complex elaboration of a comprehensive plan. The tense relationships between the actors in this domain are taking place against a backdrop of rapid demographic and economic growth, which sharpens urban development issues. While Austin's attractiveness is set as an exemplary model of the success of creative class theory, the goal of this work is to reveal the role of the various types of models in the structuring and evolution of Austin’s planning culture.The first section specifies the research objects and develops an appropriate methodology. The study of the urban planning culture is based on the analysis of urban planning professionals and on the comparative analysis of urban planning cultures, adapting them to a larger variety of actors to take into account all the people involved through a spatial strategy. The different types of active models in the global discursive and comparative urban planning community are first defined, then considered in the light of the policy mobility studies.The second section traces the history of Austin's urbanization through the lens of the theoretical models used to study its development, while pointing out the prevailing urban models at each period. The construction of contemporary models is analyzed through their dialectical relationship with the case of Austin in order to emphasize the mechanisms of scientific modeling and the reciprocal influence between these theoretical models and the urban planning actors.The third section analyzes Austin’s planning system, its governance and the conception of the urban planning held by the various groups of actors involved. It shows that beyond epistemic communities, real cultural communities are formed around policies imagined to overcome contemporary planning issues.The last section deepens the analysis of the actors’ interplay and of preveiling urban models thanks to a planning tool: the comprehensive plan. It highlights the mechanisms of cultural evolution in the field of planning and reveals the actors’ strategies to promote new urban models.The depth of the fractures revealed within the planning field explains the difficulties for its system to evolve. Its processes therefore remain very tense and litigious. The development of a common culture of planning could gradually restore a bond of trust and replace the mistrust that, for the moment, stalls the process of adaptation to the new urban realities of an emerging big large city.
