The purpose of this thesis is to explore certain of the dynamics associated with the physical transformation of cities, using Montreal between 1846 and 1918 as a case study. Beyond the typical description or classification of urban forms, this study deals with the essential problem of how changes in form occurred as the city underwent a rapid growth and industrialization. Drawing insights from three different bodies of research---neoclassical theories of land rent, Marxian theories of capital accumulation, and space syntax theories of urban form---a theoretical and methodological approach is formulated which considers the city as a dynamic system, and acknowledges circulation as the driving force behind urban morphological change. It is argued that the built form of Montreal was continuously shaped and reshaped by the evolving strategies of a local "growth machine" which sought to reduce the turnover time of capital by "redimensioning" the urban "vascular system": that is, the streets, sidewalks, tracks, bridges, elevators, and canals, within which circulation takes place. This claim is interrogated and developed in each chapter through a series of empirical analyses utilizing evidence from several high-quality sources (e.g. atlases, municipal tax rolls, city surveyor reports, building inspector reports, photographs, and newspapers) to investigate the critical processes of building and rebuilding associated with phenomena such as destructive fires, the modernization of the port, street widenings, and the reconfiguration of the street grid. Each investigation explores the relationship between circulation and urban morphology. The series of investigations revealed certain regularities with respect to the spatial and temporal properties of morphological change. Consistent with expectations based on existing theories and research, the findings confirm the importance of centrality and accessibility to urban form, for the distribution of rents, and for patterns of land

A changing perception based on the appreciation for information in our era allows a broader idea and different understanding of life as a system driven by the flow of information. Simultaneously, our understanding of 'the' urban was broadened. It enabled us to perceive urban structures as living organisms beyond their physical manifestation and separated from human control. Like species, our cities are great products of evolutionary forces and contain invaluable information worth preserving.When writing about urban spaces, urban is understood as a system which is constituted not so much by built forms and infrastructures, but as a heterogeneous field that is constituted by intervention and lines of forces and action. These lines form the coordinates of an urban topology that is not based on the human body and its movements in space alone, but also on relational acts and events within the urban system. These relational acts can be economic, political, technological or tectonic processes, as well as acts of communication. The urban is therefore quite different from the physically defined spaces of events and movements.The focal point of this paper is to explore the relationship between the spaces of movement, the spaces of events and the relational systemic 'spaces'. It will be attempted to identify fundamental processes behind urban design. Rules are derived from connective principles in complexity theory, systems theory, pattern recognition, and artificial intelligence. / Department of Architecture

This work involves the study of the effects of land use on the chemical composition of urban stormwater runoff, and its subsequent acute toxicity to the aquatic invertebrate Daphnia pulex. Samples were obtained from the Brunette drainage basin of Burnaby, British Columbia, from a variety of sites in the land use classifications commercial (C), industrial (I), residential (R) and open/greenspace (0). Results indicate that the toxicity to D. pulex and the chemical composition of the stormwater (measured by such parameters as COD, alkalinity, hardness, hydrocarbons and trace metals) were influenced by land use and the interval between rainfall events. The industrial and commercial land use sites were the major source of those trace metals most often considered toxic to aquatic organisms, with runoff from the commercial sites proving most toxic to the test organism (toxicity followed the sequence C>I>R»0). Bioassays with synthetic stormwater (Cu, Fe, Pb and Zn, at concentrations observed from field samples) demonstrated that pH and suspended solids helped to regulate the toxicity of the trace metals, and implicated the importance of these elements in natural stormwater toxicity. Statistical comparison between synthetic and natural stormwater runoff toxicity yielded poor correlation; however, this was expected due to the inherent differences between the laboratory and field environments. A detailed study of a single storm event indicated that while the "first-flush" of the storm may be contributing to toxicity through the physical scouring of insoluble pollutants, the soluble pollutants proved to be more toxic and were washed out of the area over the entire duration of the event. This prompted the author to propose the complete treatment of all stormwater runoff, and not simply the slug load of the first hour. / Applied Science, Faculty of / Civil Engineering, Department of / Graduate

Much of the sustainable community planning and design discourse has been about prescribing and defining ends. A large gap exists between goals for sustainability and the ways and means to achieve them. Multiple barriers are encountered when implementation attempts are made. The research addresses the question: In what ways can demonstration projects increase social learning of effective planning, design and policy alternatives that assist in developing sustainable urban communities? Demonstration here is an area based, site specific planning and design process and built project showing potential adopters the benefits of employing various innovations. Five fields of scholarship and research (land-use and sustainable development; planning and design participation; urban experimentation and demonstration; innovation, diffusion and social learning; action for innovation and implementation) are drawn upon to inform the objectives. An analytical-evaluative framework for sustainable planning and design is developed, then applied in a detailed case study. The case study of Egebjerggard, a 928 dwelling, mixed use neighbourhood in Ballerup, Denmark provides an analysis of how leading practice can contribute to a better understanding of the potentials and challenges for advancing community policy, design and implementation at the neighbourhood and city-wide level. The analysis enables the interpretation of the Ballerup experience and the transfer of principles to the Canadian context. Two initiatives in sustainable community development in Calgary and Vancouver indicate the issues, opportunities and the state of practice. A proposed demonstration strategy outlines possible new institutional and organizational capacities and relationships in the Canadian residential planning and delivery system. The main contributions include: i) an empirical and descriptive-analytical case study providing a detailed account of integrated planning implementation and policy development in Denmark, ii) a strategy, its structure, organization and functions to carry out demonstration / exhibition in Canadian municipalities, iii) a normative proposition for and the evidence to support an expanded notion of demonstration directing attention to their value and potential. The benefits and returns outlined serve as a general argument for proceeding with a neighbourhood scale fully featured demonstration in any city in Canada. / Applied Science, Faculty of / Community and Regional Planning (SCARP), School of / Graduate

M.Tech. (Architectural Technology) / This dissertation explores my own neighbourhood – Roodepoort. It critically examines consumerist lifestyles which currently dominate the area and proposes an architectural intervention which will showcase new modes of living. The proposed building accommodates a cultivation school and a ‘hackerspace’ where residents of Roodepoort can learn to live more sustainable. The cultivation school recalls Roodepoort’s history as a farming area and celebrates the area’s spirit of place. The hackerspace provides a place for suburban inventors to work and collaborate.

In North Texas, the Barnett Shale underlies large areas of the Dallas-Fort Worth Metroplex (DFW), which magnifies debates about the externalities of shale gas development (SGD). Continued demand for natural gas and expansive urbanization in DFW will cause more people to come in contact with drilling rigs, gas transport, and other urban shale gas landscapes. Thousands of gas wells within the DFW region occupy a large, yet scattered land surface area. DFW city planners, elected officials, and other stakeholders must deal with current and future urban growth and the surface impacts that are associated with gas development. This research examines how shale gas landscapes affect urban land uses, landscapes, and patterns of development in DFW. The study focuses on multiple fast growing DFW municipalities that also have high numbers of gas well pad sites. This study asks what are the spatial characteristics of gas well production sites in DFW and how do these sites vary across the region; how do gas well production sites affect urban growth and development; and how are city governments and surface developers responding to gas well production sites, and what are the dominant themes of contestation arising around gas well production sites and suburban growth?

Thesis (M.Sc. (Geographic Studies)) -- University of Limpopo, 2021 / The study focuses on Extension 44 in the Polokwane, an exclusively Black urban Township defined as a liveable geographical space consisting of both activity and awareness space (perpetual) space. Central to this research is its origins and existence as part of the urban racial spatial organization of Polokwane Municipality, viewed in terms of the Colonial, Apartheid and the traditional theoretical models depicting the internal structure of urban centres, including how it fits into the post-Apartheid urban planning policies, the provision of housing (types and quality), including the availability of physical and social infrastructure, how the residents perceive and evaluate these in relation to the residents’ quality of life in that area. The questions raised are (i) when and why was Extension 44 in the Polokwane municipality established? (ii) Who provides what type and quality of housing in the township? (iii) And lastly what perceptions do the residents have regarding housing and living conditions in Extension 44? Therefore, the study draws its significance as falling under both Settlement (Urban) and Behavioural geography. The former deals with origins and the nature of habitable space (settlements) while the latter is concerned, among others, with how people perceive their habitat.
