West Bottoms 2048: growing an urban district through intermediate natures

Woodard, William Brett January 1900 (has links)
Master of Landscape Architecture / Department of Landscape Architecture and Regional & Community Planning / Jessica Canfield / The Kansas City downtown area is experiencing a population influx, which is projected to increase over the next few decades, requiring new residential areas and increased parkland in the downtown. The Kansas City West Bottoms, located between the downtowns of Kansas City Missouri and Kansas City Kansas, is an urban district plagued by vast tracts of underutilized land, poor connectivity, and vulnerability to flooding. To address the issues of the West Bottoms and the area’s need for new urban development, this project proposes the implementation of a new urban park that both supports and is supported by a new urban district. In order to transform the West Bottoms into a vibrant mixed-use community, the park and redevelopment will be phased in over a period of 33 years. Intermediate natures, landscapes that temporarily occupy and improve parts of the city undergoing transformation, will be used to preserve current open space, which will later transition into parkland as the district grows. Ultimately, West Bottoms 2048 will draw users and activity to the district while generating a lasting environmental and economic impact on the downtown area.

No. of bitstreams: 1 6446.pdf: 11130211 bytes, checksum: 632fbc7b67f6bbf4ffb13e6938458d11 (MD5) Previous issue date: 2012-07-26 / Financiadora de Estudos e Projetos / This research seeks to meet the demand for information assisting public administrators in making decisions about urban development. Along these lines, this case study on Santa Madalena Stream watershed (SMSW), São Carlos, Brazil, aims to supplement Federal Law No. 12,651, of May 25, 2012, which establishes permanent protection areas (PPAs) adjacent to water bodies. To this end, it considers local specificities and provides a tool for protecting watersheds and improving the quality of life of surrounding populations. The main objective of this study is to develop and propose criteria and guidelines for the protection of urban watersheds through an environmental zoning (ZA) process conducive to establishing land occupancy modes and priorities as well as drawing up legal regulations on a local scope. This study indicates that the aforementioned law should take into account local demands and specificities while abiding by its fundamental principles. The procedure presented herein may ultimately contribute to public administrators‟ strategic planning for land use and occupancy and supplementing Federal Law no. 12,651 in order to promote environmental protection and urban development consistent with preserving PPAs. In carrying out this study, the researchers aimed to contribute to public administrations‟ urban planning and environmental management. In this manner, it provides a basis for establishing priority areas for environmental protection and improving public policies on this subject / Este trabalho de pesquisa foi fundamentado na necessidade de produção de informações para subsidiar o poder público no processo decisório para o desenvolvimento das cidades. Nesse contexto, o presente trabalho visa trazer subsídios complementares à Lei Federal nº. 12.651, de 25 de maio de 2012, que define as APPs marginais a corpos d'água, por meio de um estudo de caso da Bacia Hidrográfica do Córrego Santa Maria Madalena (BHCSMM), em São Carlos - SP, considerando as especificidades locais e buscando atuar como um instrumento para proteção ambiental da bacia e melhoria da qualidade de vida da sua população. O objetivo principal do trabalho é elaborar e propor critérios e diretrizes para a proteção de uma bacia hidrográfica urbana, por meio de um Zoneamento Ambiental (ZA) que contribua no estabelecimento de prioridades e modalidades de ocupação, bem como na elaboração de regulamentações legais de âmbito local. A elaboração deste trabalho evidenciou que a referida lei necessita ser complementada, de acordo com as especificidades e necessidades locais, sem ferir ou perder os seus princípios fundamentais. O procedimento ora apresentado pode vir a contribuir para o planejamento estratégico municipal de uso e ocupação do solo, no sentido de complementar a lei federal para maior proteção ambiental e desenvolvimento das cidades, compatível com a conservação das suas APPs urbanas. Com o desenvolvimento deste trabalho espera-se contribuir tanto para o planejamento urbano quanto para a gestão ambiental do município, fornecendo subsídios para a definição de áreas prioritárias para proteção e também para a elaboração de políticas públicas municipais.

Continuous flash extraction of alcohols from fermentation broth

Teye, Frederick David 30 March 2009 (has links)
A new method of in situ extraction of alcohols from fermentation broth was investigated. The extraction method exploited the latent advantages of the non-equilibrium phase interaction of the fluid system in the flash tank to effectively recover the alcohol. Carbon dioxide gas ranging from 4.2L/min to 12.6L/min was used to continuously strip 2 and 12% (v/v) ethanol solution in a fermentor with a recycle. Ethanol and water in the stripped gas was recovered by compressing and then flashing into a flash tank that was maintained at 5 to 70bar and 5 to 55oC where two immiscible phases comprising CO2-rich phase (top layer) and H2O-rich phase (bottom layer) were formed. The H2O-rich bottom layer was collected as the Bottoms. The CO2-rich phase was continuously throttled producing a condensate (Tops) as a result of the Joule-Thompson cooling effect. The total ethanol recovered from the extraction scheme was 46.0 to 80% for the fermentor containing 2% (v/v) ethanol and 57 to 89% for the fermentor containing 12% (v/v) ethanol. The concentration of ethanol in the Bottoms ranged from 8.0 to 14.9 %(v/v) for the extraction from the 2 %(v/v) ethanol solution and 40.0 to 53.8 %(v/v) for the 12% (v/v) fermentor ethanol extraction. The Bottoms concentration showed a fourfold increase compared to the feed. The ethanol concentration of the Tops were much higher with the highest at approx. 90% (v/v) ethanol, however the yields were extremely low. Compression work required ranged from 6.4 to 20.1 MJ/kg ethanol recovered from the gas stream in the case of 12% (v/v) ethanol in fermentor. The energy requirement for the 2% (v/v) extraction was 84MJ/kg recovered ethanol. The measured Joule-Thompson cooling effect for the extraction scheme was in the range of 10 to 20% the work of compressing the gas. The lowest measured throttle valve temperature was -47oC at the flash tank conditions of 70bar and 25oC. Optimization of the extraction scheme showed that increasing the temperature of the flash tank reduced the amount of ethanol recovered. Increasing the pressure of the flash tank increased the total ethanol recovered but beyond 45bar it appeared to reduce the yield. The 12.6L/min carbon dioxide flow rate favored the high pressure(70bar) extraction whiles 4.2L/min appeared to favor the low pressure(40bar) extraction. The studies showed that the extraction method could potentially be used to recover ethanol and other fermentation products. / Master of Science

The succession of a contaminated floodplain: reclaiming the West Bottoms

King, Jessica January 1900 (has links)
Master of Landscape Architecture or Regional and Community Planning / Department of Landscape Architecture/Regional and Community Planning / Timothy Keane / Kansas City is expecting a 25% growth in population by 2050. This design proposal promotes West Bottoms as a potential area to house some of the new population, and more importantly supply a live and work community for these people. West Bottoms is also home to major industry in Kansas City as well as an up and coming art culture. West Bottoms has great potential for a community that allows the existing and new population to be a part of a live-work-play community with the vacancies in the area. The projected population growth is expected to promote sprawl, further increasing the average driving time to the city. West Bottoms currently has few connections to the downtown and offers few reasons to come to the area. These connections are mainly major bridges or highways. Another issue West Bottoms faces is flooding problems from OK Creek and Turkey Creek, which lead into the Kansas and Missouri Rivers. Finally, post and present industrial soil contamination threatens the groundwater. When mixed with flooding concerns, this contamination is potentially harmful for the health of downstream cities. Drawing inspiration from travels, Kansas City charm, plants, art, and water storage, case studies were researched. Themes from each case study were quantified. These themes paired with inventory and analysis of the West Bottoms provided the basis for the design proposed here. The successional design of the area will progress from a contaminated landscape to a landscape that holds floodwater. The final design holds all of the stormwater from the 100 year 1, 2, 3, 6, 12, and 24 hour rain events. The final design incorporates areas of learning, a variety of paths and seating, a live-work-play community, clean and creative industry, and an art culture that sustains the excitement for the timeline of succession. Overtime this landscape will evolve into a new destination for Kansas City using an integrated solution remediating the soil and holding flood waters as an amenity for the new population.
