    • Second City: An Urban Revitalization Plan for Colón, Panamá

      Hyson, Kendra (The University of Arizona., 2015)
      As the world shifts towards increased urbanization, issues of social inequity also begin to rise to the forefront, often affecting most critically those citizens who are economically disadvantaged. Areas in which there are fewer resources to defend against the negative impacts of rapid urban development tend to become a detriment to those citizens living in said areas. Such is the case with Panamá, a nation suffering from economic inequality post-rapid urbanization, much to the detriment of its citizens. Even with substantial economic growth over the last decade, Panamá still boast the second most unequal distribution of income in Latin America (Archibold 2013). The “high-value” service industries that dominate the Panamanian economy total an approximate 75-80% of the country’s annual $30 billion economy – an indication of a possibly thriving job market (Lilly and Associates, 2012). This places Panamá in a unique position to begin the mitigation of economic inequality. Colón, traditionally known as Panamá’s “Second City”, is home to the largest free trade zone in the Western Hemisphere, the Colón Free Zone (CFZ), and has been greatly impacted by this uneven distribution of wealth (U.S. Department of State 2015). Even with much emphasis on improving the CFZ, via talks of a new international airport and port expansion, little attention has been given to the city’s residents (Lilly and Associates 2012). Colón’s ideal Caribbean coastal location, beautiful tropical landscapes and historic architecture make it a prime location for trade, tourism and urban development, leaving no evident reason for the desertion currently being experienced by its citizens and landscape. The number of challenges facing Colón coupled with the city’s historic, cultural and economic significance have created a complex blend of contextual factors begging for exploration. Moreover, many of the problems in Colón deserve considerable analysis as it is in desperate need of revitalization. These challenges, problems and ongoing concerns, however, are far beyond the scope and depth of the time allotted for this master’s report. Nevertheless, this project intends to highlight some of the key components prohibiting Colón’s development, transforming those constraints into opportunities for growth. The focus of this master’s report is to investigate and conceptualize potential solutions to the issues plaguing Colón. Primarily, this report will examine what contributions landscape architectural strategies can provide to the city of Colón in helping increase quality of life for its citizens. Through cultural resilience strategies, green infrastructure, increased connectivity and sustainable tourism practices, the culminating design attempts to demonstrate how Colón can be restored to its former status as a bustling metropolis of tourism and trade.
    • The Sensory Garden Experience: A Sensory Enrichment Design for the Arizona School for the Deaf and Blind

      Pedersen, Christian; Blazquez, Oscar; Livingston, Margaret; Stoltz, Ron (The University of Arizona., 2013)
      The focus of this master’s report was to examine the sensory garden experience - a comforting space that emphasizes the broad stimulation of all 5 of the user’s senses. Tucson’s beautiful Arizona School for the Deaf & Blind (ASDB) provides an education and sense of place for its students and community; moreover it serves as a cultural resource and center for Deaf culture and developing young minds. However the problem is that the campus truly lacks an outdoor space that unifies the campus as a whole and provides an enhanced sensory experience for its student body and populace. The intent of this master’s report was to develop a set of comprehensive guidelines and principles that designers will be able to use in the future to enhance the sensory experience for deaf and blind users. These guidelines have been applied towards the design of a master plan for the Arizona School for the Deaf and Blind located in Tucson, Arizona. The sensory garden serves as a means of providing students, faculty and guests with an opportunity to interact with the environment, engage in passive recreation, spaces for opportunistic meetings, the promotion of cultural awareness, and last it provides all of its users with a heightened sensory experience. This report has investigated: the various components of a sensory garden, the concept behind sensory designs, and how our senses interact in relation to spaces. The report also examined potential design standards used in DeafSpace and blind spaces, and last it examined sensory mapping and how its methods are involved in the design process.
    • Sensory Gardens for Children With Autism Spectrum Disorder

      Johnson, Lauri M; Wilson, Beverly Jean; Johnson, Lauri M (The University of Arizona., 2006)
      One of every 166 children born today could be diagnosed with Autism Spectrum Disorder (ASD) (CDC 2006). Growing bodies of evidence show sensory integration issues may be at the root of many of the symptoms children with ASD exhibit. Sensory integration is defined as the ability to feel, understand, and organize sensory information from the body and environment. The issues surrounding sensory integration are reflected in both hypersensitive and hyposensitive reactions by children with ASD to the vestibular, proprioception, visual, audio, tactile, and olfactory senses.The goal of this paper is to address the sensory integration issues of children with ASD by creating a sensory garden which would allow them to focus on therapeutic and diagnostic interventions. By using the principles and elements of design, guidelines for this garden focused on producing calming effects for hyper reactive children with ASD and stimulating effects for hypo reactions.
    • Shading coefficients of six tree species in Tucson and their impact on annual energy loads

      McPherson, Gregory; Dougherty, Eileen, 1958- (The University of Arizona., 1988)
      This study determined winter and summer shading coefficients for six commonly used landscape trees in Tucson using a photographic dot-matrix method. Tree types were developed from this data reflecting canopy density, shape, and foliage periods, then applied to SPS and MICROPAS computer programs to model effects of tree shade on annual energy loads for three residential construction types. Statistical analysis showed pruning to have a significant effect for 5 of the 6 species tested. Significant differences were also found among species and within species due to seasonal effects in foliage density. Shading scenarios manipulated the number and location of tree types were modeled. Greatest net annual savings were from 3 African sumac trees located on the west side of a masonry house typical of the 1950s (121). Shade from tree species found to have significantly different shading coefficients (10%) did not substantially increase energy savings ($5-12).
    • Site planning in Guadalajara architecture education: An exploratory study

      Gimblett, Howard R.; Vergara, Santiago (The University of Arizona., 2000)
      In recent years, the use of site planning in architecture has significantly increased. However, a large number of architecture schools in Mexico have not included this subject in their educational profile. This may strongly impact regions where there is an absence of city planning-related disciplines to cover this demand. This study explores how professionals, professors and students of architecture schools in Guadalajara, Mexico, perceive the importance of site planning in their profession and examines the potential of expanding these concepts in their curricula. This study found that site planning concepts and applications are considered essential knowledge for Guadalajara architects' education. Aso, a high potential for expanding site development issues, the use of systematic approaches, and the incorporation of tools was found.
    • THE SOLAR VISTA: Integrating solar energy into our neighborhood parks

      Livingston, Margaret; Johnson, Aaron (The University of Arizona., 2019)
      Urban ecology emerged, in the 1970’s, as a response to the increasing reality of growing populations causing environmental and health problems of both urban and non-urban dwellers. As such, human settlements were acknowledged by ecologists as legitimate areas of ecological study. Almost 50 years later, great strides have been made to improve the ecology within our cities. This Masters Report looks to build upon past success by rethinking the implementation of sustainable practices into the urban fabric of a city. The report examines a contextually suburban park within Tucson, Arizona as an opportunity to better integrate and showcase the, increasingly popular and affordable, practice of harnessing solar energy. A review of literature and design projects was conducted to gain an understanding of ecological design principles, multi-functional solar sites, and educational features in public spaces. Site inventory and analysis revealed the existing condition of the site, as well as possible design limitations and opportunities. In response to the research and site assessment, design solutions were made to further progress the ecological practices within our public spaces.
    • Songs of Chansons D' Haute Ville: Strategies for resilience within a rural heritage landscape

      Cottrell-Crawford, Penelope (The University of Arizona., 2020)
      Songs of Haute Ville is a culmination of my passions for heritage conservation, landscape architecture, and climate adaptation. The report will identify strategies to build physical and social resilience within a rural French heritage site called Haute Ville. The name means “high town” in French, as the site clings to a hill which overlooks the village of Puget-Ville in the valley below. The site is the original footprint of Puget-Ville, and it remains a wellspring of natural and cultural heritage resources for the town. Within the site's bounds are an 11th-century chapel, a 14th-century castle ruin, and footprints of the medieval village, all nestled within an dense pine-oak forest. In recent decades, the historic site has seen unprecedented damage from droughts and extreme weather impacting the hillside location. Major pathways have been rendered inaccessible due to landslides from eroded soils and rock-slides from destabilized masonry. This damage has impacted the site’s capacity to host visitors and events, which in turn has created ramifications for restoration and fundraising efforts. My Master’s Report will provide typologies for erosion mitigation and acoustic appreciation spaces; designs for re-vitalized entrance areas; and recommendations for native planting and alternative event programming. This project has ties to my personal heritage as well: my grandparents were live-in stewards of for almost four decades, until 2018. I have been fortunate to spend valuable time there throughout my life, exploring the lands, touching the stones, witnessing the hillsides change in wind and sun and rain. As such, has been a great pleasure to write this report, and to share it with my family, who are all intertwined with the site. Songs of Haute Ville aims to showcase strategies for the holistic protection of our shared global heritage. Heritage landscapes are much more than the built environment: they are comprised of the cultural talismans that exist in the ecologies and accumulated memories of the places we hold dear.
    • Southside Revival: A Research-based Design Approach to Revitalizing the 6th Avenue Corridor in South Tucson

      Livingston, Margaret; Kohen, Sol (The University of Arizona., 2019)
      South Tucson, Arizona faces a slew of challenges, poor public perception, and logistical issues having to do with poor funding of redevelopment. A need exists for small town revitalization plans, rooted in main street redesign along South Tucson’s 6th Avenue corridor. Investigation into community, business, and environmental make-up was conducted, along with analysis into how policy strategies, and design solutions can be implemented. Ultimately, city-wide master planning, with a main focus on streetscape improvement through high-profile public amenities, could foster a framework for private investment, and improved public image.
    • Spatial Journeys: Eco-Tourism in the Lower Delta Region of the Colorado River & the Upper Gulf of California.

      Clement, Caryl; Frederickson, Mark; Glenn, Edward; Jones, Warren (The University of Arizona., 2000)
      The northwestern region of the State of Sonora, Mexico is an area rich with cultural and bio-diversity. In recent years, over-fishing of this area coupled with the disappearance of the Colorado River Delta waters has caused a marked decline in the fishing industry. Local economies have suffered causing a trend of the young adults to move away from their homes in order to find viable occupations. Eco-tourism is a viable alternative, potentially improving the current economic decline of the local communities and maintaining the cultural family structures. Examination of the cultural, economic and environmental needs of the area and the preferences of eco-tourists, indicate the possibilities for a sustainable, low impact eco-tourism program. An integrated form of Eco-tourism is proposed for Cienega de Santa Clara, with other potential sites for Eco-tourism tourism activities identified within the region bounded by the Colorado River Delta Biosphere Reserve to the north, extending south through to the small fishing village of El Golfo de Santa Clara. The recommendations proposed are based on the integration of the following: the desires and needs of the locals, involvement of the locals at all levels, strategies that are sensitive to the environment, the desires and needs of Eco-tourists and the needs of outfitter guide services. A pro-active approach will be implemented in conjunction with a an American based company, Southwest Trekking, through the employment of pilot trips, surveys and structured interviews with locals residents and environmental scientists.
    • A Study of Impact of Urbanization on Ephemeral Streams in Headwater Watersheds in Eastern Pima County, AZ.

      Kumazawa, Naoto.; Kim, Mintai; Livingston, Margaret; Lopes, Vicente; Nichols, Mary H. (The University of Arizona., 2004)
      In this study, the impact of urbanization on ephemeral streams in arid environments was assessed by comparing eight small headwater watersheds with different degrees of urbanization in Tucson, Arizona. Chronological change in urbanization, stream network, and downstream channel width were observed, employing GIS, orthophotos over thirty years, and field measurements. A decrease in drainage density caused by urbanization and a decrease in channel width were found in many study sites. The relationship between the chronological change in downstream channel width and the urbanization pattern in the watersheds was assessed using an index named Stream Based Urbanization Index that indicates spatial distribution of urbanization in watersheds in relation to streams. Based on the comparison of seven Index factors, a lower rate of decrease in channel width was observed in the watersheds with a higher urbanization, especially with a higher concentration of urbanization near streams among the general trend of channel narrowing.

    • Subsurface irrigation of turf: An examination of current methods

      Deeter, Michael T.; Schmoll, Timothy Jon, 1942- (The University of Arizona., 1991)
      This study examines literature on subsurface irrigation of turf using published and unpublished sources to determine its relevance for the designer of irrigation systems. It looks at two installed sites to determine current industry practices and then develops a model to assist the designer of these systems. Finally areas in need of further research and technical development are suggested. Literature is not readily available to the designer and it is sometimes contradictory. Case studies show that subsurface irrigation is an effective method of irrigating turf, especially in arid parts of the world. A model to select tubing and emitter spacing is developed by summarizing existing literature and case studies. Virtually all areas of design, installation and management need further research. Two primary areas that need further investigation are specific design issues and benefits to the end user such as cost, water savings and maintenance procedures.
    • Sustainable Landscape Development of Urban Waterfront: A waterfront park design along Sanjiao Lake, Xinmin River and Taizi Lake in Wuhan Economic Development Zone in China

      Lu, Li; Frederickson, Mark; Livingston, Margaret; Blazquez, Oscar A. (The University of Arizona., 2013)
      As an important natural resource, urban watercourses have a close relationship with urban development, such as significant connectivity, ecological values and recreational opportunities. Unfortunately, conservation and development of urban waterfronts have not received sufficient attention in many cities in China. Rapid urban development in China has led to decrease in urban watercourses, degradation of urban riparian areas and water pollution. This work focuses on strategies for developing waterfront areas along Sanjiao Lake, Xinmin River and Taizi Lake which is located in Wuhan Economic Development Zone, China.
    • Sustainable Urban Waterfront: Re-imagining Waterfronts as Inclusive Public Spaces

      Quinn, Kelly, James (The University of Arizona., 2012)
      Concerns for sustainability and the environmental management processes that contribute to it, is of critical importance to the future growth of cities throughout the world. Cities located along river corridors, lakes and coastal waterways have a greater concern as human migration to these areas has increased over the last several decades. Bordered by water, these communities must make use of limited land while protecting critical natural resources from damage due to their continued growth. From ancient times, such urban settlements and their ports were intimately related in both functional and spatial terms (Hoyle and Pinder) owing their prosperity to waters usefulness and ease in transportation and trade. In port cities today, the symbiosis between water and human based functions has changed dramatically, challenging cities at times to reclaim industrial and derelict properties and transform them into spaces that expand economic growth, protect public health, the environment, and create a sense of place for local residents. The goal of this project is to identify design guidelines that fall within the parameters of sustainable and smart growth planning and develop a model for a sustainable waterfront redevelopment project. The challenge in this project is to develop a model that meets 3 distinct design criteria: 1. Restore the biological and physical structure of the water and shoreline where possible. 2. Enhance the existing waterfront facade and landscape. 3. Allocate space for the areas cultural, social and public programs throughout the entire project. Coastal and waterfront communities around the world have a distinct sense of place created by their history and geographic location. Some of these once thriving maritime communities, over time have deteriorated into underutilized, obsolete and often contaminated properties. Bordered by water, coastal communities are challenged to make use of limited land, while protecting the natural resources from the effects of urban growth. Taking advantage of and reinvesting in these pre-disturbed coastal areas, communities can once again thrive, bringing value back to both the economy and the community. Living near or on the water historically has been and is expected to remain very desirable. Take for example the United States. In the U.S., coastal cities cover less than 17% of the land area yet 52% of the U.S. population lives within that area, and that number is expected to grow (Smart Growth manual 3). In third world countries that number is even higher due in part to the number of jobs available and the overall quality of life in these areas is better. Panama City is no different. The city is in the midst of its own population explosion. At the beginning of European settlement (1501), historians estimate that the entire population (some 60 tribes) of what is now the Republic of Panama was between 500,000 and 750.000. (U.S. Library of Congress) Today, the city hosts a population of just over 1.2 million people, roughly 52% of the countries entire population. (U.S. Library of Congress). According to the world bank, Panama is an uppermiddle income developing country that suffers from extreme income inequality affecting 40% of its population. (World Bank.org)
    • THE TACOMA FLATS A study of post-industrial urban waterfront rejuvenation

      Herman, Brandon (The University of Arizona., 2014)
      Named after nearby Mount Rainier, Tacoma has been on a slow but steady rebound from the economic decline of a postindustrial nation. Founded at the terminus of the Northern Pacific Railroad in 1873, Tacoma’s economy was historically based largely on the exportation of natural resources, such as timber and coal. Although still trying to find its stride, this Pacific Northwest city has retained, for the most part, the blue collar industrial grit that the city was originally founded on. Like most industrial cities, Tacoma suffered a prolonged decline in the mid-20th century. An effect of suburbanization and disinvestment, the city still finds many of its historic structures and vacant parcels largely underutilized. However, since the 1990’s, the city has felt some effects of reinvestment. The University of Washington integrated a Tacoma campus into the Downtown core, Tacoma Link, the state’s first light rail line, and the Thea Foss Waterway urban waterfront redevelopment all helped to provide the local economy with a much needed boost. Additional investments in the downtown include the restoration of Union Station and the creation of the Museum District, which includes The Museum of Glass, Bridge of Glass, Tacoma Art Museum, Washington State History Museum, Lemay-America’s Car Museum, Children’s Museum of Tacoma, and Foss Waterway Seaport - a centuryold shipping warehouse and maritime heritage educational center. Tacoma also posses a thriving theatre district. Perhaps we have disinvestment to thank for the lack of redevelopment that has ultimately lead to the preservation of vast blocks of historic Tacoma. This fact, along with a more affordable housing market, and greater investment interest help lay the foundation for a future as a complete and healthy metropolitan center. This city inherently holds many of the desirable amenities, spatial arrangements, and historical vernacular that other cities around the country are trying to recreate post urban renewal era. The Tacoma Flats programming and design makes many assumptions regarding the future of this city - a fully realized economy, a large regional population expansion, and increased efficiencies in port functions. This 2050 vision is just that, a glimpse of how underutilized former industrial areas adjacent to the downtown core could be used to accommodate the growth, health, and ecological function of this historically rich region of the Puget Sound. The Tacoma Flats 2050 vision is simply the realization of possibilities.
    • Techniques for improving established golf courses: Restoration, renovation, and redesign. An improvement plan for the Meadow Club (Fairfax, California)

      Livingston, Margaret; Thawley, Mark Todd (The University of Arizona., 2000)
      This study clearly defines and identifies the difference between the terms, restoration, renovation and redesign. In order to understand characteristics found on golf courses built in different eras, the history of golf course architecture has also been summarized. Research was gathered from eight courses that have recently completed some type of improvement project or that are currently undergoing improvements. The results show that the process of improving golf courses built before World War II differs considerably from improving those built after the War. Through neglect the former have lost many unique design characteristics and are therefore worthy of restoration. Based on the results of this study, key factors for successful restoration have been identified and applied to the Meadow Club, a course that is currently planning improvements. Built in 1927 the Meadow Club was originally designed by legendary golf architect, Alister Mackenzie.
    • Theory and Design Considerations of a Saline Ecological Landscape: A constructive method to reduce brine waste volume

      Bresdin, Cylphine; Glenn, Ed; Scott, Beth; Blazquez, Oscar (The University of Arizona., 2013)
      Pertinent abiotic and biotic factors and their interdependencies necessary to comprehend the ecology of saline systems are investigated and evaluated. A designed saline ecosystem is proposed as a constructive method to reduce waste volume. Landscape pattern is investigated as the vehicle for an evapotranspiration induced directional saline gradient. A demonstration site is used to explore conceptual design application of the idea of ecosystem pattern consisting of a linear sequence of ecotopes, each displaying its own ecological community in relation to salinity range and site context. Biota is relinquished to self-organization. Potential for research use of the ecosystem is illustrated.
    • The therapeutic values of gardens and landscapes

      Zube, Ervin H.; Batelli, Penny Lynn, 1963- (The University of Arizona., 1998)
      Research has shown that plants, gardens, and nature can promote and enhance human health and well-being. A review of the relevant literature examined human-environment relationships and the possible therapeutic benefits derived from these relationships. In addition to the research literature, therapeutic gardens designed by landscape architects were examined. A comparative analysis between various theories within the research literature, and between the research literature and executed designs was performed. This analysis resulted in design suggestions and guidelines from the point of view of fostering human health and well-being.
    • Tomorrow's Garden: Uniting Tradition Technology Community

      Kindler, Brad (The University of Arizona., 2019)
      Today challenges of climate change, population growth, biodiversity loss, and water scarcity, lead farmers to ask new questions about how to grow food in a changing environment. Additionally, innovative technology and public food preferences present challenges and opportunities for farmers to consider before planting. Honoring Tucson’s diverse community and unique history, this study proposes the design of Tomorrow’s Garden. This garden seeks to punctuate Mission Garden’s historic timeline with a demonstration of sustainable and innovative agricultural practices. Outcomes of this proposal include the design of a garden that has the capacity to adapt to changing climate, as well as build community through design process and project implementation.
