This thesis analyzes best practices of both brownfield redevelopment and transit-oriented development and identifies both conflicts and opportunities for synthesis. Transit can rekindle demand for otherwise undesirable brownfields along rail corridors. While brownfields, when redeveloped with transit in mind, can increase transit ridership and, therefore, increase the viability of transit. Transit-oriented development on brownfields increases the complexity of the development, but the best practices of each have many commonalities. The most effective tools reduce developer time, cost, or uncertainty, and preferably all three. The City of Indianapolis has the opportunity to create transit-oriented development on brownfields along the proposed Northeast commuter rail corridor on existing rail right-of-way. An investment in transit would provide an opportunity to both remove the environmental contamination along the rail line and to make development in many inner-city neighborhoods more desirable. / Brownfield redevelopment : history, barriers and best practices -- Transit-oriented development : history, barriers and best practices -- Synthesis of best practices in transit-oriented development and brownfield development -- Opportunities for transit-oriented development on brownfields in Indianapolis. / Department of Urban Planning

The topic of this diploma thesis is revitalization of brownfields - reuse of abandoned, unused or devastated areas and objects. The main objective is to describe the location of the selected brownfield and to analyze the possibilities of its new use. Following objective is own site design, based on a previous analysis of brownfield usage suggestions. There are examples of successful revitalization of other brownfields in this thesis. The theoretical part of the thesis includes information obtained from specialized literature, monographs, journals, conference proceedings and Internet sources in Czech and English. This is a general issue of brownfields (their definition, typology, the origins and reasons for creating brownfields, existing databases, legislation related to the topic, opportunities for revitalization of brownfields and financing of revitalization). Practical part of the thesis deals with specific choosed territory, its description and it especially analyses two suggestions for its new use. It includes the characteristics of area of Beroun and the choosed site, SWOT analysis, spatial studies and analysis of new site usage suggestions. The subject of interest is the brownfield site of the former TIBA a.s. company located in Beroun. The thesis also respects the conditions for the functional use of the site, which were taken into account in the analyzed proposals as well as in the own proposal.

This thesis focuses on classification and evaluation of brownfiled sites in the South region in the Czech republic. The thesis is divided into two parts, theoretical and practical. The theoretical part is aimed at defining the issues of brownfields, particulary to the development and current status of brownfileds not only in the South region. The classification of brownfields is part of the chapter. In the second part is applied the model based on the scoring of the parameters.

This thesis deals with the roles of various stakeholders in urban development process and simultaneously with the process of transformation and brownfields regeneration in inner part of Prague. The area of case study, lower Holešovice and lower Libeň, has unique specifics: location is close to the city center and also to Vltava River and has a number of development areas. The thesis is based in theoretical foundations of urban regeneration, brownfields, concepts of urban development and systems of governance. The aim is to find out who are the most important stakeholders of urban development and their impact on the area of the case study. The practical part of the thesis is based on interviews with multiple stakeholders from public, private and non-profit sector as well as on an analysis of Prague`s official planning documentation. The results of the thesis underline different approach and engagement of various stakeholders, but also the assumption of significant changes in functional land use, structure and appearance of the area. Key words: urban regeneration - brownfields - urban planning - stakeholders of urban development - Holešovice - Libeň - Prague

The subject of the diploma thesis is the design of a city block on brownfield areas in the Trnitá district of Brno. The aim was to make the most out of the land, minimize motor traffic and create objects with different functions (housing, administration, amenities, services) will be mixed. The main part of the whole area will be the Ponávka river, which will take advantage of the great potential of the watercourse, thus creating a quality public space for recreation. The principles of multiplicity and porosity have been used to design - from the maximum land abandonment, the mass was gradually taken away to create apartment houses, administrative areas, a common parcel with civic amenities and a walkable green roofs.

This thesis is focused on the revitalization of brownfield implemented through public producrement and selected in the city of Brno. The theoretical part includes basic concepts that explain the issue of brownfields, public procurement, and more specifically the assessment of their economic efficiency. The practical part is focused on the specific case of brownfield revitalization through public procurement including its economic assessment. The use of econimic analysis, namely Cost Benefit Analysis (CBA), will be utilized to assess the effectiveness, and socio-economic impacts will also be determined. The purpose of the second part is to determine whether the revitalization thus made more economically advantageous for the city of Brno.

Doctor of Philosophy / Department of Agronomy / Ganga M. Hettiarachchi / Urban gardens have been a popular re-use option in the transformation of brownfields—located in older industrialized cities and near peri-urban developments. They provide accessible, available, and affordable supplies of fresh fruits and vegetables, effectively reducing the enigma of “food deserts” across U.S. cities. However, direct (soil ingestion, inhalation) and indirect (soil-plant-human) human exposure concerns about real or perceived trace element contamination in urban soils persist due to previous use. Elevated lead (Pb) and/or arsenic (As) concentrations were found at two (Tacoma and Seattle, WA) urban gardens. The Tacoma site was contaminated with Pb (51 to 312 mg kg-1) and As (39 to 146 mg kg-1), whereas soil Pb at the Seattle site ranged from 506 to 2,022 mg kg-1, and As concentrations were < 20 mg kg-1. Experimental design at both sites was a randomized complete block with a split-plot arrangement (main plots: biosolids/compost vs. non-amended control; sub-plot: plant type). Tacoma site treatment included a Class A biosolids mix (TAGRO) with dolomite. The Seattle site was amended with Cedar-Grove Compost (CGC) plus dolomite. Efficacy of biosolids/compost amendment in reducing Pb and As concentrations was evaluated using root, leafy, and fruit vegetables. Soil Pb and As bioaccessibility were also evaluated. Food chain transfer of Pb and As in vegetables due to surface contamination of produce samples were evaluated on the basis of cleaning procedures. A laboratory incubation study and a controlled greenhouse experiment were conducted on soils collected from the Tacoma site. Effectiveness of addition of laboratory synthesized ferrihydrite (Fh: iron oxyhydroxide) and TAGRO mix, each alone or in combination were screened and tested on the Pb and As co-contaminated Tacoma soil. Extended X-ray Absorption Fine Structure (EXAFS) spectroscopy studies of Pb and As were conducted on incubation study samples to understand treatment-induced Pb- and As-speciation changes. Dilution of soil Pb (10 to 23%) and As (12 to 25%) were observed for biosolids amendment at the Tacoma site, while CGC amendment resulted in 20 to 50% dilution in soil Pb at the Seattle site. Biosolids and CGC amendments reduced Pb concentrations in the vegetables by 50% to 71%. At both sites, Pb concentrations of root vegetables exceeded the MLs established by the Food and Agriculture Organization (FAO) and the World Health Organization (WHO). Arsenic concentrations in vegetables were below an estimated ML and were reduced by 46% to 80% when grown on biosolids amended soils. Laboratory cleaning further reduced Pb and As food-chain transfer in vegetables grown in contaminated urban soils. Laboratory incubation and greenhouse studies showed dissolution of Pb in TAGRO plus Fh, and Pb concentrations in Fh amendments were significantly lower than the other amendments. Bioaccessible Pb and As were low. Significant reductions in bioaccessible As were observed when soils were amended with both TAGRO and Fh. X-ray absorption spectroscopy results indicated that chloropyromorphite-like (stable Pb phosphates) phases were the most dominant Pb species. Arsenic existed mainly as As5+, scorodite (FeAsO4•2H2O)-like species in all the treatments ranging from about 60% (control) to about 70% (TAGRO plus ferrihydrite). Amendments utilizing both biosolids and Fh significantly reduce human exposure risks present in urban soils contaminated with Pb and As.

This creative project studies the potential that brownfield redevelopment can have on revitalization efforts in small towns and rural areas. Three key research questions guide the study: What is a brownfield and why is it difficult to redevelop them? What approaches can be used to overcome the problem of brownfield redevelopment, specifically in small cities? and How can design apply methods that allow the redevelopment of a brownfield to play a part in community revitalization?Part II and Part III compose the main body of the project. Part II defines brownfields as "Real property, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant." The brownfield dilemma is part of the larger problem of urban decline and suburban sprawl and has many causes. A lack of environmental contributed to the formation of the brownfield problem. Other factors include changes in the global economic system, and the effects of environmental laws. CERCLA, an act enforced through the EPA, has had a particularly strong impact on the sale and redevelopment of industrial real-estate. Growing stocks of brownfields are contributing to economic, environmental, and socio-cultural problems across the country. Because the available financial resources, the culture, and the people of small towns are different from large urban areas, the brownfield problems of small towns are different. However, brownfields hold promising advantages, even for small towns when they are properly integrated into revitalization efforts. Although it is important for these efforts to be focused at the local level, success is ultimately determined by the quantity and quality of regional networking and involvement in state level programs such as voluntary cleanup programs.Key methods and strategies can also be used to help ensure the success of a brownfield as a revitalization catalyst. Raising local awareness and funding, an inventory of the area's brownfield problem, planning and outreach, environmental site assessments, clean up, and choosing appropriate end-uses are the basic steps of the process. One of the most vital elements of this process is involving the community in every step. It is especially important to have heavy public involvement in choosing the end-uses for the new development. End-uses such as public parks, waterfront development, museums, community centers, and other facilities supporting a strong civic network are shown to act as catalysts for the revitalization of surrounding commercial areas.Part III of this study discusses concepts from the design theory of multi-use and infill developments, and public and civic space design. A discussion about the Keller Manufacturing site then leads to the formation of a master plan for the redevelopment of the site. This master plan serves as an example brownfield site redevelopment in a small town. / Department of Landscape Architecture
