    Growth and expansion in post-war urban design strategies: C. A. Doxiadis and the first strategic plan for Riyadh Saudi Arabia (1968-1972)
    (Georgia Institute of Technology, 2009-11-19) Middleton, Deborah Antoinette
    This dissertation resituates C. A. Doxiadis in Post-War urban design history with a detailed examination of how urban growth and change was addressed by urban design strategies as applied in the master plan for Riyadh Saudi Arabia, undertaken between 1968 and 1972. The Riyadh master plan commission is important within Doxiadis' career, occurring in the midst of his prolific writing projects and approximately eight years after he completed the Islamabad master plan, his most renowned project. Most Post-War architects focused on the socio-spatial components of urban life, elaborating architectural projects that intertwined transportation, infrastructure, and concentrated on mass housing strategies. This dissertation argues that Doxiadis' contribution to urban design theory and practice during the Post-War period was to define a rational scientific methodology for urban design that would restructure settlements to enable urban expansion and change while addressing issues of community building, governance and processes of development. The applied urban design for Riyadh Saudi Arabia strongly exemplifies Doxiadis' rational strategy and methodology as outlined in Ekistics theory and the conceptual model of Dynapolis. The comparative analysis examines how Doxiadis applies the Dynapolis model in the urban spatial planning of Riyadh to organize urban territory at the macro and local urban scales, define neighborhood communities, and connect the new master plan to the existing spatial territory of the city. The longitudinal analysis contrasts the Doxiadis master plan, Riyadh's first urban development strategy, to the most recent comprehensive approach MEDSTAR to understand how the Doxaidis' urban design has sustained its spatial continuity over time. This dissertation makes two significant contributions. The first is to broaden knowledge of Post-War urban design specific to the spatial problem of urban expansion and change, and second to resituate Doxiadis within the Post-War history of urban design specifically revealing his previously unrecognized project of the Riyadh master plan undertaken from 1968-1972.

    Coding the urban form
    (Georgia Institute of Technology, 2009-05-04) Habeeb, Dana M.
    What are the essential characteristics that constitute historic American neighbor- hoods? Do current regulations promote developments that exhibit these essential characteristics? In this thesis I analyze two historic neighborhoods in an effort to un- cover their architectonic principles. By identifying the key components that comprise these places, we can critically analyze whether regulations, such as Historic Preserva- tion Ordinances and the SmartCode, are adequately designed to govern development practices of residential neighborhoods.

    Designing density: increasing functionality through flexibility in single family neighborhoods
    (Georgia Institute of Technology, 2009-04-29) Smith, Alyson Rae
    American cities have only recently come of age in the global sense. Therefore, most of our land use regulations have emphasized greenfield development issues over those of a mature city. The next wave of city building is redensification. This thesis argues that modern day, Euclidian zoning needs to be replaced in order to make the case for a sustainable mix of residential diversity, density, and affordability. Conventional zoning relies on simplistic measures to regulate density and shape the form of neighborhoods. Initially used primarily as a way to make the field of planning appear scientific and rational, these measures do not create functionally flexible neighborhoods for the changing needs of the twenty first century. Urban spaces should be thought of as a language, composed of pieces that evolve with cultural norms. Zoning must evolve to reflect current societal values, with an emphasis on environmental issues, while meeting the needs of changing market structures if cities are ever to sustainably house their populous. Zoning's inflexibility towards cultural shifts uses antiquated assumptions to force contemporary city design into a regulatory straight jacket. Using case studies within the city of Los Angeles because of its history in side-by-side integration of single family homes with a range of residential densities and supportive commercial uses, the thesis investigates three primary questions. First, under what zoning ordinances did the Los Angeles neighborhoods evolve and what lessons in functionality can be taken from their design? Second, looking at both conventional zoning and newer, form-based regulatory techniques, how does zoning affect the variety of housing types available? And third, what would a flexible zoning framework, created to support the future development of an evolving regional urbanization process and a changing social demographic, look like?
