Sur le front. Pour une approche géographique du front d'urbanisation: lotissements, voisinages, trajectoires

Abstract : On suburban fringes, the structuring of neighborhoods relies on fragmented and reticular morphological patterns. Based on a case study in Southern California, this research proposal highlights the outcomes of master planned communities as a major type of morphology on the metropolitan fringe (vol 1). Planned communities are investigated, both theoretically and methodologically (spatial analysis) so as to jointly confront the issues of spatial morphology (streets layout of dead-ends, lollipops and loops) and social morphology (homogeneity), as subdivisions are built according to social expectations of homogeneity by design and by regulations (CC\&Rs). But spatial fragmentation and reticular relations both challenge classical methods of urban analysis. An investigation of neighborhoods in post-suburbia requires a better theoretical understanding of the relationships between subdivisions and the various contexts that define a multi-level vicinity, with intricate effects produced by several geographical level in which the subdivisions are embedded: the community, the local jurisdiction, etc. Furthermore, urban fringes are constantly readjusting, with a continuous dynamic of fragmentation and in-fill developments; this requires to account for temporality and its interaction with the neighborhood. The argument is threefold. First, the logics of production of subdivisions and planned communities are discussed, investigating the actors (developers, homeowner associations, planning authorities...), and the environmental policies at stake requiring more density, in order to define subdivision morphologies as a proxy to analyze the making of local territoriality. Second, local contexts are analyzed, discussing on the one hand social interactions, proximity and the neighborhoods, and on the other hand using property price as a proxy to analyze the geography of the neighborhood in terms of multilevel interactions with social contexts and local politics of urban amenities financing. Third, socio-economic trajectories of suburban neighborhoods are analyzed, in order to delineate radical contexts of valorization, upgrading or downgrading of neighborhoods with respect to price and socio-economic attributes. In vol. 2 (appendices), teaching, research and administrative experiences are detailed, and a selection of relevant publications are detailed by thematics: private urban governance, neighborhoods, trajectories and metropolitan dynamics.
