Inner city blighted industrial sites are primarily associated with the general phenomenon of deindustrialization within the post-industrial inner city that is caused by spatial and functional restructuring of the industrial activity. Blighted industrial sites are vacant, obsolete, or underutilized industrial buildings, facilities and other related industrial functions and areas. Such blighted areas may have physical, functional, social, economic, and environmental impact problems both within the site, as well as on surrounding properties. Brownfield sites represent a severe form of blighted sites which include real or perceived environmental contamination. Brownfield redevelopment requires environmental clean-up to acceptable regulatory standards which may result in a costly process. The general research goal is to achieve an understanding of this complex problem context as well as to establish the pertinent planning framework for redevelopment of blighted industrial sites within the Canadian inner city. The research process includes three parts. Part One includes an extensive preliminary literature review of brownfield redevelopment case studies in Canada, United States, and the United Kingdom. It also includes an outline of general planning theory and related interdisciplinary theories. The preliminary findings of literature review reveal a multiple component interactive problem context that indicates a need for an integrative planning framework addressing multiple problem components. The preliminary research findings for the planning framework are further studied and examined in four empirical case studies included in Part Two. The specific research objectives and research questions address three constituent parts of the planning framework including the nature of the problem context, potential policy directions, and the planning process. The central research question is “what is the appropriate planning framework and approach for brownfield redevelopment given a multiple component interactive problem context? Part Three synthesizes the findings of Parts One and Two, which highlights the proposed planning framework for brownfield redevelopment, including an outline of major problems and policy directions based on impact evaluation by key participants in the empirical case studies, as well as outlining the main characteristics of the planning process. Some of the main problems and issues include site contamination and related legal liabilities, cost of site remediation that may exceed property value, stakeholders’ conflicting objectives, social stigma associated with brownfields, clarity and consistency of the environmental approval process as, community support. The proposed policy directions also represent multiple components and they are mainly as follows: • To prepare an inventory of brownfield sites, • To establish public-private partnership for project financing especially for site remediation, • To develop self-financing mechanism (like TIF/TIEF) to finance cost of site remediation, • To establish a redevelopment authority that is directly responsible for the process, • To foster public-private-community collaboration and partnership, • To secure accessibility of local residents to newly provided opportunities (like jobs), • To adopt multiple-component integrative planning framework to link major problem components and planning sub-processes The research findings also highlight the planning process being manifested at two main poles including the project developer and his consulting team, the public approval authority, in addition to community residents and interest groups that are involved in the public consultation process. The development approval process is the common organizational set-up and interface for stakeholders’ involvement in the process. The main characteristics of the proposed planning process include multiple-component multi-disciplinary context consisting of interactive planning sub-processes within each component, multi-level spatial contexts, involvement of multi-stakeholders with conflicting objectives and vision, incrementally adaptive, critical time and timing context, and mixed-rationality comprehensive planning vision. This research asserts the need for addressing the multiple components of environmental, physical, economic, social, and political planning without prior bias or predominance to any of these components. This also asserts the need for multi-stakeholder public-private-community collaboration and partnership.

Most property development firms who invest in property will need to raise some extra financial support. Unforeseen or unexpected expenses can arise at any point in time during the development process. Calculated decisions should be taken with regards to the financial circumstances for any property development project. Decisions should be taken not only for the present but for the future as well. It is therefore important to understand the market and the current economic conditions before applying for capital to fund a property development project. There several types of finance available to fund property development, these include long term borrowing, short term borrowing, construction loans property development investment trust, second mortgages. There is risk to all of the aforementioned finance available.

La réhabilitation des friches industrielles dans les zones urbaines est un enjeu majeur pour le développement durable des villes. La gestion et la reconversion de ces sites, imposées par la réglementation, nécessitent toutefois le développement d’outils d’évaluation des risques environnementaux et sanitaires, et de techniques de remédiation durables. Cette thèse a porté sur la mise en place d’outils multidisciplinaires pour la gestion durable des sites pollués, avec le cas particulier d’un site de recyclage de batteries au plomb caractérisé par une pollution historique en plomb principalement mais également d’autres polluants inorganiques (Cd, Sb, As, Cu et Zn), couramment définis par le terme d’Eléments Traces Métalliques (ETM). Ce travail a cherché à renseigner les mécanismes impliqués dans les systèmes polluants-sol-plantes pour renforcer la prise en compte de la qualité globale des sols dans la gestion des sites industriels, tout en essayant de répondre à des questions de la recherche appliquée. En plus des outils et procédures classiquement utilisés pour évaluer, contrôler et réduire les risques environnementaux et sanitaires causés par les sols pollués, le développement des mesures de biodisponibilité (plantes et les humains) et d’écotoxicité (différents tests biologiques: inhibition de la mobilité de daphnies, Microtox® et induction de bactéries bioluminescentes, microbiologie) permet d’affiner la classification des sols contaminés en termes de dangerosité. De plus, des plantes engrais verts (bourrache, phacélie et moutarde), communément utilisées en agriculture ou par les jardiniers (car elles améliorent les propriétés bio-physico-chimiques des sols avec un système racinaire et une grande production d’exsudats racinaires), ont été testées pour la re-fonctionnalisation des sols pollués. Enfin, les mécanismes impliqués dans le devenir des polluants dans la rhizosphère et les microorganismes associés ont été étudiés. L’ensemble des résultats fourni des éléments de réponse et des moyens d’améliorer la gestion des sols contaminés par des métaux et métalloïdes. (1) Tout d’abord, la séparation par taille des différentes fractions de sol permet une réduction significative des tonnages de matériaux contaminés et donc une économie réelle lors de la mise en décharge des sols excavés avec un gain certain en termes d’empreinte écologique. (2) Ensuite, le calcul d’écoscores pour les differents échantillons de sols pollués, sur la base des résultats des essais d’écotoxicité, ont permis d’affiner plus précisemment les risques par rapport aux paramètres physico-chimiques « classiques » requis par la réglementation. Des différences de sensibilité ont été observées en fonction de la nature de l’essai biologique, l’origine de l’échantillon, les propriétés physico-chimiques et les concentrations totales de polluants. (3) Contrairement à la phacélie, la bourrache et la moutarde ont amélioré la respiration du sol, réduit l’écotoxicité et la quantité de plomb bioaccessible et totale dans le sol, respectivement par phytostabilisation et stockage dans les racines (Pb, Sb) ou par phytoextraction et donc stockage dans les parties aériennes. En outre, ces plantes pourraient être testées sur le terrain pour une utilisation en phytoremédiation des friches industrielles et des jardins modérément pollués. Selon la nature du métal, du type de sol et des plantes, la compartimentation et la spéciation du polluant diffèrent, ainsi qu’en fonction des caractéristiques agronomiques du sol et l’activité microbienne de la rhizosphère. Un criblage moléculaire et une méta-analyse de la génomique microbienne ont permis de mettre en évidence les différences dans les communautés bactériennes étudiées en fonction du niveau de concentration métallique, des espèces végétales et des caractéristiques des sols étudiés. / Rehabilitation of brownfields in urban areas is a major challenge for the sustainable development of cities. Management and conversion of these sites, imposed by regulation, however, require the development of tools for environmental risk assessment and health and sustainable remediation techniques. This thesis focused on the establishment of multidisciplinary tools for the sustainable management of polluted site, with the particular case of rehabilitation recycling of lead batteries with a mainly historical lead pollution and other inorganic pollutants (Cd, Sb, As, Cu and Zn), currently defined as Metal Trace Elements (MTE). While trying to answer questions of applied research, this work has sought to investigate the mechanisms involved in the soil-plant pollutants to strengthen the consideration of the overall quality of soil management for industrial sites. In addition to the tools and procedures conventionally used to assess, control and reduce environmental and health risks caused by polluted soils; measures of bioavailability (plants and humans) and ecotoxicity (different bioassays: inhibition of the mobility of Daphnia magna, Microtox® and induction of bioluminescent bacteria and microbiology) have been developed with the aim to refine the classification of contaminated soils in terms of dangerousness. Moreover, green manure plants (borage, phacelia and mustard), commonly used in agriculture or by gardeners because they improve the bio-physico-chemical properties of soils with a root system and a large production of root exudates were tested for re-functionalization of polluted soils. Finally, the mechanisms involved in the fate of pollutants in the rhizosphere and their microorganisms in the plant were studied. The main results provide some answers and ways of improving the management of soils contaminated by metals and metalloids. (1) First, the size separation for soil fractions allows a significant reduction in tonnages of contaminated material and therefore costs for the landfill excavated soil with a gain result in terms of ecological footprint. (2) Then, calculation for the differents polluted soil samples of eco-scores based on the results of ecotoxicity tests can discriminate more accurately compared to physicochemical parameters required by the regulations. Differences in sensitivity were observed depending on the nature of the bioassay, the origin of the sample, physico-chemical properties and total concentrations of pollutants. (3) Unlike phacelia, borage and mustard improve soil respiration, ecotoxicity and reduce theamount of bioaccessible and total lead in soil, respectively by phytostabilisation and storage in roots (Pb, Sb) or phytoextraction and storage in aerial parts. Further, these plants could be field tested for use in phytoremediation of brownfields and gardens moderately polluted. Depending on the nature of the metal, the type of soil and plant, compartmentalization and speciation of the pollutant differ, and in conjunction with agronomic characteristics of soil and rhizosphere microbial activity. Molecular screening and meta-analysis of microbial genomics have enabled highlight differences in bacterial communities studied by species and growing conditions.

The expansion of suburbia into undeveloped lands has had a major effect on our urban environments. These effects have resulted in both businesses and residents leaving cities for the greener pastures of suburbia. As a result many neighborhoods in cities such as Detroit have been left vacant and rundown. These left over sites offer a chance to bring new life to the communities in which they are located. New affordable communities can be created within the urban core, thus providing a new start for local residents and a reason for suburbanites to relocate back to the city.This project will be focusing on a redevelopment plan for the Historic Ford Model-T factory in Highland Park, Michigan. This small community lies within the borders of the city of Detroit and suffers from many of the previously described problems. Inadequate housing is a major issue for the city's residents along with the negative image that these vacant and run-down buildings portray. Recent developments show that there is an interest in reinvestment within the city through two recently constructed shopping plazas, and a new industrial complex that are within one city block of the site. Providing appealing housing options incorporated with places of business, can bring life back to a city that has lost so much as seen in other communities. The advent of the affordable automobile and highway system has helped in the demise of this community. This site is an important link to the areas past and present heritage as the motor capital of the world. Henry Ford was very involved in the creation of communities by building entire towns in order to provide housing for his workers, which is why this site is perfect to redevelop with housing. The main goal for this project is to create a better place to live for the current and future residents and a place that symbolizes the identity of its rich manufacturing past. The final product will be a conceptual master plan that will fit within an urban environment and meet the needs of the community. The methodology that I will use will consist of literature review and case studies of similar projects. It is my intention that this information will aid me in creating a conceptual master plan based on my two primary goals: to create a safe and unique place for the residents to call home and create a catalyst for more development. / Department of Landscape Architecture

Because many of the preserved buildings and sites function as public destinations, interpretation has the opportunity to provoke new learning experiences. In this project I examined the Thomas Kay Woolen Mill as a case study for interpretive methods of industrial historic architecture. Through reviewing current interpretive methods, describing a broad historical context, conducting interviews with Salem residents who took part in the work at the mill between the 1930s and the 1960s, and researching specific mill workers' housing in Salem, I found that the inclusion of human stories can benefit the interpretation of the architecture. By offering a specific human narrative against the background of a wider history, an exhibit can challenge the visitor to see the building in a new way. / Committee in Charge: Dr. Leland M.
