Resilient cities: an analysis of resilient urban form

(Georgia Institute of Technology, 2014-08-27) Aguilar, Johnny R.

This thesis studies the theories, scientific evidence and spatial relationships within urban form to determine means and deviations that developments can use to determine the resiliency of urban form within a given location. Resiliency within urban form functions as modulations around a morphological mean. Rather than replicate the mean, resilient cities modulate with low standard deviations around the mean. As a result, while many look aesthetically different, resilient cities are structurally more similar than dissimilar. Cities can use this information to inform their projects on a schematic design level to determine if they are improving their urban form or if they are deviating from the resilient mean.
Bantam towns of Georgia: Small town revitalization and economic development

(Georgia Institute of Technology, 2014-05-19) Riley, Rebecca Dawn

Over 80-percent of the U.S. population lives in urban areas that occupy a mere 3-percent of the country's total area. Development problems and infrastructural stress caused by urban overpopulation can already be seen in the nation's largest cities. Scattered across North America are small towns that, at one time, were largely sustained by agriculture or industry, but have watched as farming and manufacturing operations leave them behind. Rooted in these economic conditions is the growing gap between metropolitan and nonmetropolitan areas. The high concentration of rural lands and high poverty rates in the South makes this region particularly vulnerable to the effects of rural economic distress, and put it in desperate need of solutions. For many small towns in Georgia, the last two decades have brought either rapid population growth, as seen in the areas surrounding Atlanta, or great population decline, most clearly depicted in the southeastern region of the state. Each condition produces a host of different challenges for these small communities, illustrating no simple solutions. It is the focus of this research to determine what proximities, economic assets, and formal characteristics are necessary for small towns in Georgia to successfully revitalize and grow. Furthermore, it is the aim of this research to present a means of analyzing the assets of small towns in order to determine where outside investment is most likely to make a difference, and how resources can best be utilized.
Retrofitting closed golf courses

(Georgia Institute of Technology, 2014-05-16) Plummer, Audrey L.

In the 80s and 90s in America, residential developers believed that the best way to make money was to build a golf course community. Premiums of homes on golf courses ranged from 30% to 100% more than the price of a similar home not adjacent to a course. Today, the bottom has fallen out of the golf market leaving over 2,400 courses closed in America. Residential homes bordering a closed golf course experience an 11.7% loss of value. Many owners and potential developers want these large parcels of land to be up-zoned so they can build higher density residential and make a profit. Neighbors do not want to lose their greenspace and public officials do not want to be seen as harming single-family residential. This thesis argues that to retrofit a closed golf course, developers, community members and other stakeholders must first understand the morphological and environmental implications of the different types of golf courses, the context surrounding closed courses and the location of these courses in a greater regional area. By understanding closed golf courses in this way, a framework can be established that results from negotiation among golf course residents, neighbors, developers and public officials.
Floating Tybee: planning and designing for rising seas

(Georgia Institute of Technology, 2014-05-16) Manley, Canon Randolph

There is a statistically high probability that within this generation's lifetime, the mean sea level in the south eastern coast of the United States will rise from three to six feet above what it is today. The easiest response to this scenario and its complicated and devastating repercussions is to flee, or to put up a wall. This reaction is defending current lifestyles and cultures against the liabilities and complicated problems associated with sea level rise. This thesis asks: "How can we convert the liabilities of sea level rise into assets?" Using Tybee Island of Chatham County, Georgia as a case study, this thesis will answer this question by exploring 5 topics: 1. Understanding sea level rise 2. Understanding barrier islands of coastal Georgia and Tybee Island 3. The current Sea Level Rise Adaptation Plan for Tybee Island and Where it is Lacking 4. A new urban design strategy in planning for sea level rise on Tybee Island 5. Existing instances of aquatic and amphibious architectures and a new type of amphibious architecture for Tybee Island
Designing diverse neighborhoods

(Georgia Institute of Technology, 2011-09-02) Wu, Kathryn K.

This thesis argues for diversity as an important element for urban neighborhoods. This argument is framed by three questions. First, what are the recent findings from urban design, planning and architecture research and practice about achieving neighborhood diversity? Second, what are the physical ingredients of traditional, diverse urban neighborhoods that enable diverse populations, lifestyles and incomes? Third, what design strategies can be formulated, based on the evidence above, to design and implement diverse neighborhoods? Three neighborhoods in Atlanta are the focus of the detailed analysis of diversity. These are: Inman Park, Ansley Park and Virginia-Highland. These three neighborhoods were chosen because of their similarities. They all appear to be single family detached neighborhoods but are actually diverse in terms of housing type and owner/renter occupancy; they are perceived to have unique identities in architectural styles, but actually have a diversity of styles and ages of buildings. They all are perceived to be fully gentrified but in fact, house diverse populations in terms of age, income, race and lifestyle. The conclusions of this thesis include written recommendations, based on current neighborhood design ideas as supported by the analysis of Atlanta neighborhoods.
Rethinking downtown highways

(Georgia Institute of Technology, 2010-12-21) LaRoche, Lealan Dorothy Marie

Freeways have had a strong influence not only on the urban transportation but also on downtown areas both physically and socially. Certainly, they have extended the commuting limits of the city and made lower land costs more accessible. However, many of the mid-century freeways, once championed by planners as tools for urban renewal, have created swaths of blight through city neighborhoods. Their negative impacts on the larger urban framework requires new ideas for healthier alternatives to aid in preserving and building sustainable cities. Removal of any downtown highway requires careful thought— even more consideration than when it was built. Quick solutions are what resulted in the problems that downtown highways of the Interstate-Era have today. If it is the simple interactions between people and place are that make up the positive aspects an urban environment, then what are the possibilities and strategies for removing urban highway, which are one of the primary impediments separating people in place in contemporary cities? This question is the focus of this thesis. At its core, the removal of freeways represents a trade-off between mobility objectives and economic development objectives. Evidence from other cities’ decisions to redesign or remove their downtown highways suggests multiple benefits. Making design changes, such as to replace a downtown highway with a well-designed surface boulevard, can stimulate economic activities without necessarily causing traffic chaos. Solutions come in different shapes and sizes. The selected case studies in this thesis reflect a diversity of approaches – suggesting no single strategy exists for addressing downtown highway issues. This reflects the fact that multiple alternatives must be considered in every situation because each approach varies in costs and opportunities. A typology of highway alternations derived from the case studies includes seven different techniques: burying, demolishing, taming, capping or bridging, elevating, retaining, and relocating. The final chapter applies the conclusions from the case studies to the Downtown Connector– Interstate 75/85– in Downtown Atlanta, Georgia. Urban design and transportation planning has an emerging new set of values. Transportation planning is seeking to promote alternate modes of transportation to the private vehicle, like transit, by foot, or by bicycle. We now understand that connectivity is not served only by highways but also by urban street networks that invite modes other than just automobiles. An important role for urban design will be to shape the way these interactions are made to benefit the citizens, its urban spaces, and the economy.
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?
Big boxes and stormwater

(Georgia Institute of Technology, 2008-07-11) Fite-Wassilak, Alexander H.

Big-box Urban Mixed-use Developments (BUMDs) are mixed-use developments with a consistent typology that incorporate big-box retailers in a central role. They are also becoming popular in the Atlanta region. While BUMDs serve an important economic role, they also cause issues with stormwater. This study explores integrating a on-site approach to stormwater management into the design of BUMDs. These new designs not only significantly lower the amount of stormwater run-off, but also have potential for better, more attractive, developments.
