This research frames the city within three root values upon which all decisions made in the city are based. The three root values are continuity, connection and openness. Under the present priorities of city making, the contemporary city is heavily biased toward continuity. A paradigm shift is required in the way cities are conceived and developed to rebalance the three root values with the intention of creating cities that are better places for humans to inhabit. This shift is a call for a more human city. This research investigates a collection of urban design principles that are intended to humanize the city and improve them as settings for human use and occupation. The research utilizes the festival as a temporal moment in the city of uniquely human-centered use. It is a moment in which the human becomes the dominant priority in the organization and occupation of space, while other systems of the city are temporarily interrupted. Through a series of six festival case studies a number of consistent adaptations of space emerge in which the festive events highlight strategies for humanizing space in the city. The urban design principles highlighted by this research include adapting spatial containment, restructuring movement, exposing meaning and commonality, attracting density of people, removing separation of uses, increasing overlapping activities, and spatially and temporally scripting and choreographing all of these strategies. / (cont.) These principles are then examined through a design test that shows their applicability in making humanizing adaptations of space and ultimately creating more human cities. / by Joshua Charles Fiala. / M.C.P.

They resemble their distant relative, also known as the trolley, in many ways but express a contemporary, provide modern conveniences, and act as a magnet for redevelopment within the city. Modern streetcars build on the theory behind the European tram systems and provide desirable transportation options to support a range of densities in urban living. Currently in the United States, Portland, OR and Seattle,WA operate one modern streetcar line and have plans to expand their singular line into a network. Using these two routes, the plans for system expansion, and the individual cities that support them as case studies, this thesis analyzes the potential for streetcars to return to Denver, CO.The analysis for the Mile High City was conducted using my knowledge of and research on Denver and the surrounding metropolitan region, its historical skeleton that developed around the streetcar, and the City's current trends in public transportation and planning processes. Based on a multifaceted analysis that includes studying the relationship of potential streetcar route length, multi-modal connections, major destinations, high bus ridership routes, projected residential density, projected employment density, and redevelopment potential based on use and zoning, Denver is in fact an appropriate city for the return of streetcars. / (cont.) Not only would one streetcar be successful, but an integrated system could serve the City and its surrounding urban neighborhoods well. Taking the analysis one step further, the research attempts to compare a potential modern streetcar system for Denver with the historic streetcar routes that operated until 1949. Many observations arise, including the obvious difference in the limited number of modern lines versus the vast number of historic routes. Modern streetcars typically occur on primarily mixed-use corridors rather than pass through strictly residential neighborhoods as they once did. It is also evident that modern streetcars in Denver would direct redevelopment within the city whereas historic streetcars directed development to the edge of the city.This ability to direct development and redevelopment within the city's boundaries in addition to providing transportation fit in line with Denver's goals for growth management, multi-modal transportation options, and neighborhood revitalization. / by Sarah E.

It is estimated that there are seven parking spaces for every vehicle in the nation; given that a vehicle can be in only one place at any given time, there are underutilized, vacant parking spaces all around us. This thesis argues that vacant parking spaces create an opportunity for more intense use of the land. It investigates which types of surface parking lots are best suited for which types of activities, based on physical design characteristics, multiple-use considerations, and a zoning and regulatory framework. It recommends the most attention is given to parking lots in neighborhood commercial areas and large surface parking lots that occupy entire city blocks. The thesis argues for the creation of more part-time public spaces through the use of underutilized parking lots. This argument is partially based on public spaces' social benefits, increased economic development potential, linkages with increased public health, and aesthetic-related benefits. Issues raised in creating public spaces on parking lots (both public and private lots) are addressed and possible approaches to overcome these obstacles are suggested. Strategies for creating more use on surface parking lots are identified from a municipal perspective, for those who coordinate events on parking lots, parking lot owners, and for developers. / (cont.) The thesis concludes with a discussion on implementation of creating more use on surface parking lots through zoning standards, design guidelines, and publicity strategies. The thesis concluded with a theoretical discussion on the ideal types of conditions for increased use on surface parking lots. The overarching finding is that the challenge of constructing more use on surface parking lots is primarily an issue of having the will to work through the necessary bureaucratic codes and regulations; by posing strategies to help facilitate this process, a palette of ideas for creating more use on surface parking lots can be utilized by any interested stakeholders. / by Kathleen Kane Ziegenfuss. / M.C.P.

CCS technology is currently in development and requires higher construction and operating costs than is currently competitive in the private market. A question that policymakers and investors have is whether a CCS plant will operate economically and be able to sell their power output once built. One way of measuring this utilization rate is to calculate capacity factors of possible CCS power plants. To investigate the economics of CCS generation, a marginal cost dispatch model was developed to simulate the power grid in the Western Interconnection. Hypothetical generic advanced coal power plants with CCS were inserted into the power grid and annual capacity factor values were calculated for a variety of scenarios, including a carbon emission pricing policy. I demonstrate that CCS power plants, despite higher marginal costs due to the operating costs of the additional capture equipment, are competitive on a marginal cost basis with other generation on the power grid at modest carbon emissions prices. CCS power plants were able to achieve baseload level capacity factors with $10 to $30 per ton-CO2 prices. However, for investment in CCS power plants to be economically competitive requires that the higher capital costs be recovered over the plant lifetime, which only occurs at much higher carbon prices. To cover the capital costs of first-of-the-kind CCS power plants in the Western Interconnection, carbon emissions prices have been calculated to be much higher, in the range of $130 to $145 per ton-CO2 for most sites in the initial scenario. Two sites require carbon prices of $65 per ton-CO2 or less to cover capital costs. Capacity factors and the impact of carbon prices vary considerably by plant location because of differences in spare transmission capacity and local generation mix. / by Gary Shu. / M.C.P. / S.M.in Technology and Policy
