A risky project evaluation technique called the fuzzy real options analysis is developed to evaluate brownfield redevelopment projects. Other decision making techniques, such as multiple criteria analysis and conflict analysis, can be incorporated into fuzzy real options analysis to facilitate negotiations on brownfield redevelopment among decision makers (DMs). The value of managerial flexibility, which is important in negotiations and policy making for brownfield redevelopment, is overlooked when the traditional evaluation method, net present value (NPV), is employed. Findings of this thesis can be used to promote brownfield redevelopment, thereby helping to eliminate environmental threats and enhance regional sustainability. A brownfield is an abandoned or underutilized property that contains, or may contain, pollutants, hazardous substances, or contaminants from previous usage, typically industrial activity. Brownfields often occur when the local economy transits from industrial to service-oriented seeking more profit. Governments actively promote brownfield redevelopment to eliminate public health threats, help economic transition, and enhance sustainability. However, developers are reluctant to participate in brownfield redevelopment because they often regard these projects as unprofitable when using classic evaluation techniques. On the other hand, case studies show that brownfield redevelopment projects can be good business opportunities for developers. An improved evaluation method is developed in order to estimate the value of a brownfield more accurately. The main reason that makes the difference between estimates and ''actual'' values lies in the failure of the deterministic project evaluation tool to price the value of uncertainty, which leads to efforts to enhance the decision making under uncertainty. Real options modelling, which extends the ability of option pricing models in real asset evaluation, is employed in risky project evaluation because of its capacity to handle uncertainties. However, brownfield redevelopment projects contain uncertain factors that have no market price, thus violating the assumption of option pricing models for which all risks have been reflected in the market. This problem, called private risk, is addressed by incorporating fuzzy numbers into real options in this thesis, which can be called fuzzy real options. Fuzzy real options are shown to generalize the original model to deal with additional kinds of uncertainties, making them more suitable for project evaluation. A numerical technique based on hybrid variables is developed to price fuzzy real options. We proposed an extension of Least Squares Monte-Carlo simulation (LSM) that produces numerical evaluations of options. A major advantage of this methodology lies in its ability to produce results regardless of whether or not an analytic solution exists. Tests show that the generalized LSM produces similar results to the analytic valuation of fuzzy real options, when this is possible. To facilitate parameter estimation for the fuzzy real options model, another numerical method is proposed to represent the likelihood of contamination of a brownfield using fuzzy boundaries. Linguistic quantifiers and ordered weighted averaging (OWA) techniques are utilized to determine the likelihood of pollution at sample locations based on multiple environmental indicators, acting as a fuzzy deduction rule to calculate the triangle membership functions of the fuzzy parameters. Risk preferences of DMs are expressed as different ''ORness'' levels of OWA operators, which affect likelihood estimates. When the fuzzy boundaries of a brownfield are generated by interpolation of sample points, the parameters of fuzzy real options, drift rate and volatility, can be calculated as fuzzy numbers. Hence, this proposed method can act as an intermediary between DMs and the fuzzy real options models, making this model much easier to apply. The values of DMs to a brownfield can be input to the graph model for conflict resolution (GMCR) to identify possible resolutions during brownfield redevelopment negotiation among all possible states, or combinations of DMs' choices. Major redevelopment policies are studied using a brownfield redevelopment case, Ralgreen Community in Kitchener, Ontario, Canada. The fuzzy preference framework and probability-based comparison method to rank fuzzy variables are employed to integrate fuzzy real options and GMCR. Insights into this conflict and general policy suggestions are provided. A potential negotiation support system (NSS) implementing these numerical methods is discussed in the context of negotiating brownfield redevelopment projects. The NSS combines the computational modules, decision support system (DSS) prototypes, and geographic information systems (GIS), and message systems. A public-private partnership (PPP) will be enhanced through information sharing, scenario generation, and conflict analysis provided by the NSS, encouraging more efficient brownfield redevelopment and leading to greater regional sustainability. The integrated usage of fuzzy real options, OWA, and GMCR takes advantage of fuzziness and randomness, making better evaluation technique available in a multiple DMs negotiation setting. Decision techniques expand their range from decision analysis, multiple criteria analysis, to a game-theoretic approach, contributing to a big picture on decision making under uncertainty. When these methods are used to study brownfield redevelopment, we found that creating better business opportunities, such as allowing land use change to raise net income, are more important in determining equilibria than remediation cost refunding. Better redevelopment policies can be proposed to aid negotiations among stakeholders.

Brownfield redevelopment is called upon to remedy damaged ecological, economic, and social conditions due to contamination from prior land use(s). It can be utilized as a means for revitalizing low-income neighborhoods and communities of color that have suffered from years of economic disinvestment and a polluted environment. Critics of brownfield redevelopment in low-income neighborhoods argue that this form of revitalization can backfire when property values and rental prices rise and existing residents are pushed out. The City of Oakland has demonstrated a form of inclusionary brownfield redevelopment that incorporates housing that is affordable to existing residents in the area and thus avoiding the form of exclusionary housing witnessed in other cases of brownfield redevelopment in central cities. This report builds on the hypothesis that inclusionary brownfield redevelopments in Oakland can serve as a model approach for other cities in preventing displacement of lower income, residents of color through gentrification. / text

Typical of many American downtowns, Austin, Texas, has experienced renewed interest in redevelopment over the past two decades. Following City policies, this redevelopment has tended to be mixed-use in nature and has included elements of placemaking and walkability. A glaring exception to recent trends is the Capitol Complex, an area north of the State Capitol building that is home to various state government office buildings. The Capitol Complex displaced a more traditional mixed-use neighborhood in the 1950s and has been plagued by disjointed planning activities ever since. Recent budgetary challenges and a shortage of office space have prompted the state government to reexamine the Capitol Complex as a target for redevelopment. This professional report scrutinizes the Capitol Complex as a “non-place” that is challenged by walkability issues in an effort to make recommendations to ensure successful redevelopment that is more consistent with that found in the rest of downtown Austin. First, the literature on placemaking and walkability demonstrate what the Capitol Complex lacks. A case study provides a good comparison to see what policies have helped to improve districts near state office buildings. Second, the history of the Capitol Complex provides context for how the area became what it is today. Third, a land use and walkability analysis utilizing GIS along two corridors in the Complex and a pedestrian count show that the area is unfriendly to pedestrians and lacks activity on nights and weekends. Finally, the report offers both policy and urban design recommendations to help ensure that redevelopment activities contribute to make the Capitol Complex a walkable “place.” / text

As cities across the world have grown and continue to grow in many ways and for many reasons, it is anticipated that the growth of population will come from all over the world. In turn, it will influence on our urban environment economically, socially, culturally, and ecologically. Like other cities, London is making a plan -creating 326,000 new homes and 776,000 jobs - to tackle issues of the city. A series of new emerging developments across London will contribute to the changing face of the city. A lot of interventions spreading through the city are focused on the economic forces and to take advantages of real estate of London by projecting offices, apartment which is mostly market-housing, and hotels. They swept away existing contexts and replaced with higher density buildings obtaining large profits, building high rise, filling gaps between buildings with gated car parks on the ground floors, and building over open spaces. Ground floors remain blind, and tall office blocks make the overshadowed open square inhospitable and wind turbulence. Most initiatives do not seem to contribute to urban life, but may possibly become the slums of tomorrow. Now, it is time to think about how to make sense of an environment which is safe, pleasant and healthy with a sense of identity, and how to contribute to neighborhoods, visitors and new comers. In dense inner city area, since place is an invitation where neighborhood meets city, urban design must meet needs of commuters, visitors, travelers, and residents equally by combining place, amenity, and movement. Therefore, this study is to investigate ‘How city’s agenda combine with, and support local neighborhood needs’, and to redefine the quality of city life through qualities of comfort, accessibility, amenity, education, experience, and nature. / text

As the demand for center city living in the US has grown, housing has been used to revitalize neighborhoods and contribute to the tax base of the city. I investigate the ways that change, fostered and shaped in part by federal and local housing and planning policies, affects low income neighborhoods undergoing redevelopment at the level of “community.” To study these issues I study the Washington, DC neighborhoods of Columbia Heights: In less than ten years, this neighborhood was transformed by planning and housing policies from a primarily low-income, isolated neighborhood to a truly mixed income neighborhood housing residents of varied ethnicities and income levels. Using an ethnographic approach, I interviewed residents, policy makers, agency staff, advocates, and housing developers; conducted archival research on planning documents, newspapers, blogs, neighborhood list-servs, and public hearing proceedings; and observed - both directly and as a participant – in public parks, commercial establishments, public hearings, community, tenant and organizational meetings, and at rallies and town halls. My findings suggest that the District of Columbia, neighborhood groups, housing advocates, and developers instituted some of the best practices in urban planning and housing policy, which led to a mixed income neighborhood with a focus on dense, mixed-use and multi-modal transit oriented development. However, in spite of – or perhaps because of – dramatic changes in the concentration of poverty, through the combination of the preservation of existing affordable housing and the addition of higher income new residents, low income residents’ sense of community, political power and access to amenities changed significantly. Moreover, the focus on place and physical amenities that has been a hallmark of large scale redevelopment has implicitly devalued less tangible elements of neighborhood life related to use-value, community cohesion, and culture. Further, the implied benefits of mixed income communities for low income households, combined with the narrative of urban decline and rebirth that echoes across American cities have combined to justify the social, political and physical displacement of existing residents. / text

The following dissertation examines the role of collaborative planning in the redevelopment of National Priorities List Superfund sites and the implementation of Superfund site redevelopment plans. To examine the effect of collaborative planning, two models were constructed: one to predict Superfund site redevelopment and one to predict implementation of Superfund site redevelopment plans. Two test the two models, data was collected primarily from a survey of federal cleanup managers conducted between August 2008 and April 2009. Variables were then constructed and tested using bivariate and multivariate regression analysis. Results from the statistical analysis suggest that use of collaborative planning is positively and significantly associated with Superfund site redevelopment. Collaborative planning’s effect on Superfund site redevelopment plan implementation was inconclusive. To further explore the role of collaborative planning on Superfund site redevelopment and plan implementation, four case studies were developed that describe redevelopment planning at four Superfund sites. Overall, results suggest that collaborative planning is an important tool for the facilitation of Superfund site redevelopment. The effect of collaborative planning on plan implementation is somewhat ambiguous. Additional research is necessary, however, to draw firmer conclusions regarding both phenomena. / text
