EMERGENT DESIGN IN LANDSCAPE ARCHITECTURE THE APPLICATION OF THE THEORY OF EMERGENCE TO THE CRAFT OF CREATING PUBLIC URBAN SPACES Matthew Biesecker Auburn University College of Architecture, Design and Construction School of Architecture Master of Landscape Architecture This book is dedicated to my Father, Lewis Biesecker. I believe it would have made him proud. ACKNOWLEDGEMENT I am deeply grateful for having a dedicated and talented thesis committee consisting of Dr. Rod Barnett, Professor Jocelyn Zanzot, and Dr. John Pittari. Your criticism, though sometimes tough to bear, has been motivational throughout this project and will continue to be in the future. To advisors present at my presentations: Professors Rod Barnett, Jaclyn Barnett, David Hill, Charlene LeBleu, Justin Miller, John Pittari, Micheal Robinson, and Jocelyn Zanzot; thank you all for your valuable criticism. I would like to thank 2010 MLA Graduate, Alex Bonda, for his support while simulating the de- sign test. I would also like to thank you for being a good travel companion and having an extended music playlist for the five hour drives to Asheville. I wish you the best of luck in your professional career. To Professor Charlene LeBleu, you are greatly appreciated by myself and my family. You have been an absolute blessing and you are a won- derful teacher. Thank you for allowing me the op- portunity to learn, gain experience, and financially afford graduate school through the Graduate Re- search Assistantship. Throughout my life I have been blessed with honest, humble and devoted friends and family, of which, I am grateful to have. I would like to thank four people in particular. ?Momma,? you have been a positively sustained presence in the lives of your children. I have loved you always, but the older I become the more I admire you. You have so graciously endured the events life has brought you and it has been a pleas- ure to share everyone of them with you. I am thank- ful for your commitment to be available when I?ve needed a friend to support me. Kellie B, I am so proud of you and your achievements. You should take time to appreci- ate how wonderful you are. Thank you for being an amazing sibling and good friend. I would like to thank my uncle, David Hal- ford, for allowing me to stay at his home while con- ducting site visits. This has not only saved me mon- ey, but helped me to take time to relax and reflect on the elements of life that are truly important. And to my lovely Mandy. Mostly, I thank you for not screaming ?HECK NO!? and sprinting in the other direction. You have been extremely support- ive over the last several years. You have motivated me to do my best; while, at the exact same-time, completely distracting me from doing my work. I thank you for checking my grammar; for I know that is a year?s worth of work in itself. Although you cor- rected almost every line in this book (which could mean you are co-author), you must admit, the mis- spellings, repeated words, run-on sentences, and misused ?a?s? and ?an?s? led to some very interest- ing and poetic writing styles. Life consists of only a few moments, moments I can?t wait to experience with you.

The theory of emergence, which was developed in the 1970s, is currently finding applications in the design disciplines. Because the built environment is now largely considered an emergent phenomenon, emergence might be used to obtain design goals using behaviors found in the urban realm. This thesis examines how the theory of emergence can be applied to a design methodology used to create a public urban space. The ultimate goal of creating an emergent design methodology would be to create an urban network that functions at a higher organized complexity than it did prior. It is hypothesized that if a higher organized complexity is generated, an even higher level of organized complexity will emerge because of the original increase in organized complexity. The strategy for researching this thesis is divided into two major sections: (1) determining the definition and sub-theory of emer- gence that is most appropriate for the application to the design methodology for creating public urban spaces, and (2) constructing a repeatable design methodology for creating a public urban space based on the application of the selected definition and sub-theory to a design test. The success of this examination is based on its ability to gener- ate conceptual design methodologies and prompt further examination in the application of the theory of emergence to other sub-fields in landscape architecture. If an emergent design methodology can be created the inhabitant?s desires can be reflected in the design of public urban spaces in a more direct manner than most current spaces. KEYWORDS Emergence, organized complexity, public urban spaces, design methodology I. INTRODUCTION 1.2 Plan of the Palace of Versailles 19Introduction INTRODUCTION This thesis examines how the theory of emer- gence can be applied to the design methodology used in creating a public urban space. It has one primary goal: to create a design methodology (or a design proc- ess) based on the application of the theory of emer- gence that is suitable for guiding the transformation of a site from a private urban space to a public urban space. The study also has secondary goals which attempt to define the current state of research in the application of the theory of emergence to the craft of landscape ar- chitecture, extending that conversation, and postulating the future direction of research in this area. This investigation began, as so many others do, by a smaller study guided by personal interest. My in- terest in the history of the urban form, the application of science and philosophy to landscape architecture, and contemporary issues and theories in landscape archi- tecture naturally led me to examine the contemporary interpretation of the Baroque French formal garden. This early study found that the Cartesian method, the paradox of science, philosophy, and religion found in the 17th Century influenced the master designers of the time to create amazing landscapes that demonstrated not only the artistic expression of these scientific the- ories, but as a functional implementation as well. In other words, the deeply layered designs found in the gardens at Vaux-le-Vicomte and Versailles were inter- pretations of how the universe was perceived at that time (Weiss, 1996). As this idea was translated into modern times, I found that landscape architects have translated scientific trends to obtain their design goals for as long as humankind has existed. Thus, in order for me to translate the Baroque French Formal Garden into contemporary landscapes, the contemporary scientific equivalent of Descartes? Scientific Revolution must be determined. Thus, I answered the original question and brought me to my personal discovery of the theory of emergence. 1.3 Centric Diagram of the Sun King This revolving diagram shows the centric nature of the the Palace of Versallies and the Sun King, Louis XIV. 20 Matthew Biesecker Several connections were found between the theory of emergence and many of the issues that have plagued landscape architecture over the last decade. The most fundamental and binding question of the array of questions that could possibly be addressed was how could a product of landscape architecture adapt to its fluctuating context. The possibility to answer this ques- tion is based on the research and practical application of the theory of emergence over the last half century. If the fields of computer science, mathematics, and eco- nomics can use emergence as a means to reach goals or answers, then why not landscape architecture? The theory of emergence was developed ap- proximately in the 1970s. It answered many questions about how the behavior of certain populations create the forms they do. From this initial series of discover- ies, three distinct phases have occurred in the applica- tion of the theory. In the first phase, early discoveries in emergent behavior were rooted in biology and ecol- ogy. Examples of this movement include the history of how flocks of migrating birds or large schools of fish can maintain their form despite not having a leader. As the decades passed, the second phase brought a more defined understanding of emergence and what systems are emergent. During this phase, the current under- standing and principles of emergence were discovered, which views emergence as the movement from lower level simplicity to higher level complexity. The third and most current phase is using the theory to attain prede- termined goals. Only a small group of fields, mostly lo- cated in computer science, have successfully created objects or processes that use emergent behavior to gain a goal or complexity previously unattainable (Johnson, 2001). Over the last half century, urban theorists have applied the theory of emergence to better understand the spontaneous behavior of cities (Wiscombe, 2006). Their findings were similar to that of biologist or ecologist when they applied emergence to their fields(Johnson, 2001). The earliest and most influential researcher in this application was the writer and urban theorist Jane Jacobs. Her research, which was based on the spon- taneous urban life found on the streets of New York City, created her perspective that the city is a problem of organized complexity (Jacobs, 1989). Organized com- plexity is the outcome of an emergent process (John- son, 2001). This idea of city form originating from the bottom-up was starkly different from the top-down un- 21Introduction derstanding that dominated the first half of the twenti- eth century. In the 1990s, Jacobs? research, along with the contributions of Christopher Alexander and Kevin Lynch, led mathematician Nikos Salingaros to develop his theory of the urban web. Salingaros hypothesized that the ability of a city to be emergent was based on its amount and diversity of pedestrian nodes and con- nections. Essentially, Salingaros, who has a fondness for ancient urban forms, stated that the greater amount of pedestrian based transport a space has, the greater opportunity it has to be spontaneous (Salingaros, 1998). Based on the studies in the urban realm, landscape architects and landscape architecture theorists began to question why the products of landscape architecture were not emergent if the context was (Wiscombe, 2006). 22 Matthew Biesecker Based on the research that deemed the urban realm emergent, landscape architecture and landscape architecture theorist began to ponder whether the ele- ments that create the urban realm be emergent as well (Waldheim, 2001). The elements which create the urban realm are, for the most part, landscape architectural na- ture. These elements include roads, streets, parks, pla- zas, squares, and infrastructure of all types. Although this question has been examined for a decade, little at- tention has been given to the role of the theory of emer- gence in understanding the question better or answer- ing it. Despite the lack of application, there are some landscape architectural practices that use the theory of emergence to answer this question. Two of the exam- ples of this is the work of CHORA and Rem Koolhass and Bruce Mau?s project ?Tree City?. The Dutch planning, urban design, and architec- ture firm CHORA specializes in difficult urban problems that contain many stakeholders. CHORA?s principal, Raoul Bunschoten, and his students from the Berlage Institute in Rotterdam, the Netherlands developed a scenario-based design methodology that uses mostly qualitative information based on the firm?s fieldwork. CHORA and Bunschoten use a management system called the Urban Gallery to guide the evolution of a plan- ning project. The Urban Gallery is a dynamic tool that engages stakeholders to act collaboratively throughout the duration of the project. The dynamic nature of the Urban Gallery is created by its diagrammatical master plans, which generate project knowledge through its monitoring of a fluctuating and liquid design (Chora. org). Studies I have conducted found emergent be- havior in certain phases of Urban Gallery including the stakeholder feedback generated by the prototypes. But as a methodology, it denies emergent behavior to af- fect the design?s outcome. This is due to the design process?s attempt to forecast an outcome for the un- predictable future of the site. CHORA limits the endless possibilities of a place to an ?action plan? which is es- sentially a time-scaled master plan. It is suggested that the CHORA design methodology could benefit by not attempting to predict the future, but instead be suscep- tible to the unknown changes that will occur. 1.4, 1.5, 1.6, 1.7 Tempelhof Urban Ideas Competition CHORA is a scenario-based urban design frim.

Dutch architect Rem Koolhass and graphic designer Bruce Mau who entered the most unpretentious presentation in terms of physical interventions produced the winning design. They devel- oped a strategy that allowed the park?s design to adapt to the ever-changing contextual situation. Instead of proposing a design at the time of the competition, in the typical master designer fashion, they laid out a frame- work for a design process that was designed by the emerging patterns created by the individual elements that created the city. This strategy became the project?s design. Koolhass and Mau reduced the design process into what is essentially a formula. This formula is based on the principles that urban parks are a lucrative invest- ment and at the time of the competition it is impossi- ble to understand enough about the site to successfully produce a design (Waldrop, 2001). The studies of this thesis found if a truly emer- gent formula were to be created, the programed ele- ments would adapt with the desires of the individuals. For this reason, the emergent ability of Tree City is regu- lated. This formula could function in a more emergent manner if it extended the feedback loop created in the placement of elements into the selection of elements. If these two precedent studies were merged with the relative new landscape intervention strategy termed by Nan Ellin as ?vulnerable urbanism,? a unique form of design could be developed that strengthens the emer- gent behavior found in the process of design. Ellin?s approach asks landscape architects to design for an unknown future using small interventions (Ellin, 2006). These small interventions could be low in cost and use small amounts materials. This idea is in opposition to the master-planning strategy. Open-ended vulnerability could remove the restrictions created by CHORA?s and Koolhass and Mau?s ?Tree City?s? methodologies. This addition would allow the methodology?s vulnerability to create an emergent behavior instead of regulating it. Based on the these ideas and the studies of this the- sis, a design methodology can be created that exhibits emergent behavior at several levels instead of just one or two. If this can be accomplished, the understanding of how a product of landscape architecture adapt to its fluctuating context may become more clear. 25Introduction 1.8, 1.9, 1.10, 1.11 Tree City Images from the Downsview Park Competition in Toronto, Canada. (Images courtesy of Office for Metropolitan Architecture (OMA)) 26 Matthew Biesecker Based on the research of three interconnected subjects: (1) emergence as it is applied to other fields, (2) emergence as it exists in the built environment, and (3) the current-state of the application of the theory of emergence to the field of landscape architecture; a de- sign methodology has been created that exhibits emer- gent behavior during the process of design. The design should be followed as a procedure and should be ap- plied in a cyclical manner. Also, based on the research, a set of principles has materialized that help guide the design process. Project goals come in two forms: (1) holistic goals (goals that control the entire project), and (2) individualistic goals (goals that are determined in an individual phase of the design process). The design methodology?s cyclical procedure was determined as follows: {B.1} conception of the idea: this phase of the design methodology is the creation of a dream. An idea for what a site could become can come from anywhere or anyone and originate at any scale. Like most projects that arise in the public urban realm, this idea is generat- ed by the citizens, the municipality, a private enterprise, or all three together. This phase begins when change is proposed and someone makes a decision to alter the landscape. {B.2} investigation of the situation: at this point, the landscape architect should not criticize or condemn the idea or ideas brought to them in phase B.1, but de- vote him or herself to investigation of the true reason for the creation of the idea. The request for a design is sometimes based on a mis-aligned perception, which it is the landscape architect?s duty to interpret. The in- vestigation should consist of studies in the site?s history and context, current functionality and use, and its pro- jected situation. {B.3} design the prognosis: after a thorough analysis has been accomplished and the site?s situa- tion is understood, the landscape architect should pro- pose a design that is reflective of the investigation in B.2. The design should not be comprehensive, rather incremental. Early designs should be time and resource efficient in case the feedback after implementation does not propel the design forward. As the project continues into it?s later stages, more permanent elements can be designed. {B.4} calibrate the components: this phase is the actual installation of the design. {B.5} record the response: after the design is actualized on the site, rigorous efforts should be taken to document the actions that occur on the site. The data chosen to be recorded should be uniform through- out the duration of the project. The durations of time between this phase and the next can greatly differ, but the duration and routes of the recordings need to be similar. {B.6} analyze the particulars: once significant and constant data is collected, the architect must in- terpret the recordings. This should be an objective and subjective process because the feedback is considered to be hierarchical. The direction of the project should be fundamentally determined by the data, but the archi- tect?s personal ideas can influence the conclusion of the analysis. {B.7} commencement of the procedure: as the name of this phase indicates that this is not the end of the project, but yet merely a step. At this point the ar- chitect is instructed to return to step B.3. This should create a feedback and design loop that, as a whole, cre- ates emergent properties within the defined site. This loop should be continued until the calibrations reach the peak of investment. 1.12 Design Methodology Procedure This procedure should be followed in a cyclical manner, were phases B.3-B.6 repeat. 27Introduction {B.1} conception of the idea {B.2} investigation of the situation {B.3} design the prognosis {B.4} calibrate the components {B.5} record the response {B.6} analyze the particulars {B.7} commencement of the procedure conception - the originating of something in the mind idea - a thought or suggestion as to a possible course of action investigation - to carry out a systematic or formal inquiry to discover and examine the facts of to establish the truth situation - a set of circumstances in which one finds oneself; a state of affairs design - decide upon the look and function of prognosis - a forecast of the likely outcome of a situation calibrate - to adjust precisely for a particular function components - a part or element of a larger whole record - to give evidence of response - a reaction caused by a change or event analyze - examine methodically and in detail the constitution or structure of something, typically for purposes of explanation and interpretation particulars - an individual fact, point, circumstance, or detail commencement - to have or make a beginning procedure - an established official way of doing something 28 Matthew Biesecker In conjunction with the process of the design methodology, several principles were found in the re- search and testing of this design procedure. These principles are based on the nature of emergence theory and the nature of Salingaros? ?urban web.? The first principle is the acceptance that nothing an architect can design is perfect. Designs, which are located in an emergent environment are always incorrect because emergent systems are unpredictable and above the understanding of the human mind. Therefore, design calibrations should be small in physical form, inexpen- sive, consume little time, and be easily amended. The second principle states that the feedback loops or the design?s cycles should be small in duration and intimate in nature. The smaller the feedback loop, the more di- rect and intimate the design?s response to feedback can be. Finally, the architect must view him or herself as part of the emergent system. Due to the static nature of landscape elements and materials, landscape architec- tural designs cannot be manipulated in the same way a computer program can. Therefore, someone is needed to design and install the elements. But the designer is not above the system, merely an individual participating in it. After research had been conducted and a de- sign methodology had been created, the next step was to examine the design methodology in a design test. Because the design test was not actually conducted, it was necessary to create a simulation that generated response to the calibration. The simulation of feedback responses was accomplished by presenting and inquir- ing two people familiar and understanding of the site?s conditions and urban web. These people being Alex Bonda and myself, Matthew Biesecker, both Auburn University Master of Landscape Architecture students. Although the presentation of the design test may seem as if it is based on actual events, everything is simulated with the exception of for the data collected in the initial phase of analysis. 29Introduction II. THE DESIGN TEST 32 Matthew Biesecker {1.1} THE CONCEPTTION OF THE IDEA This project began when a simulated Asheville city offical approached a small simulated landscape ar- chitecture firm in Charlotte, North Carolina about cre- ating an alternate use for an economically insufficant automoblie parking lot located near Asheville?s St. Law- erence Basilica. The site already had serveral other pro- posed private uses including a highrise apartment build- ing and a multi-level automobile parking garage, but the city perferred to buy the property and transform it into a public amenity. The landscape architecture firm was given the guidelines that the alternate uses they propose must (1) be public in it?s nature, (2) genreate revenue for local businesses, and (3) create value in the properties adjactent to the site. Being a non-native to Asheville, the project?s assigned head landscape architect decid- ed to follow an untested design methodolgy, which was taughted as a way to create a public space based on an everchanging context. Because the landscape architect choose to follow that certain design methodology, the next step in the project was to study the site?s historical and current situation. 2.2 The Test Site The site chosen for the design test is an inefficient automobile parking lot in the city of Asheville, North Carolina. 34 Matthew Biesecker {1.2} THE SITE SITUATION: ASHEVILLE?S HISTORICAL AND CURRENT CONTEXT The rock at the core of the Appalachian Moun- tains and at the core of the site was formed over one billion years ago. 750 million years ago the supercon- tinent began to break apart, and 540 million years ago the continental crust split. As the continental crust spilt, the Ocoee Basin was formed and filled with seawater, while nearby rivers brought clay, slit, sand, and gravel, which settled in layers. The rocks that formed were re- sistant to weathering and erosion. As the new oceans became larger, the continental crust changed direction and collided, resulting in the formation of mountains. 240 millions years ago a new basin formed because of another change in direction of the crustal plates. This is the present-day Atlantic Ocean. At the time of their formation, the Appalachian Mountains were much taller and steeper than the present-day Rocky Mountains. For the last 100 million years, erosion has carved away at the mountains. Vegetation, wind, ice, and water still continue to erode the mountains and deposit the sedi- ment into the Atlantic Ocean and Gulf of Mexico (usgs. gov). Four times in the last 2 million years, glaciers extended southward into the United States. The gla- ciers did not reach Asheville, but the climate brought animal and plant species common to cooler, northern climates. These species established themselves and continue to live in the higher elevations of Asheville. Among these migrating species were the earliest known human inhabitants, the ancestors of the Cherokee Indi- ans (usgs.gov). 2.3 Geological History of the Appalachian Mountains Continental plate movement caused several mountains and oceans to form on the same location as the present-day Appala- chian Mountain chain. The extent of the last Ice Age is indicated in pink.

By the mid-1800?s, nearly all of the Chero- kee peoples would be removed from the Asheville area. 2.6 Map of Early European Exploration (Orange) 1540 Hernando de Soto Expedition (Black) 1567 Juan Pardo expedition 37The Design Test: {1.2} The Site Situation Origins of the title ?Cherokee? are unknown, but may translate to ?those who live in the mountains.? What little is known of Cherokee culture before the 18th century was recorded by the Spanish in their expedi- tions of the south. The first known contact between Europeans and the Cherokee tribes was in 1540 during the Hernando de Soto expedition and in 1567 during the Juan Pardo expedition. Some of these interactions were mutually beneficial, involving the trading of animals and agriculture techniques. Some of the interventions were harmful to both parties; ending in battle and the exchanging of previously unknown deceases (Conley, 2007). In the late 1600s, European?s began traveling the region more consistently because of the game locat- ed in the seeming endless wilderness. In the decades following, the Europeans and Cherokee would establish trading links consisting mostly of guns for animal pelts. In the mid-1700s, colonist from the Carolina coastal re- gion began to push the Cherokee out of their territory. This forced migration would continue for the next one hundred years and would be exacerbated by the federal land-payments given to the Revolutionary War Veterans. By the mid-1800s nearly all the Cherokee tribes would be removed from the region of Asheville. Currently, the Cherokee have reclaimed land in the region that is pro- tected by the Federal Government (Conley, 2007). 2.7 The Trail of Tears (Image authored of Robert Lindneux) 2.8 Asheville Grist Mill (Image courtesy of The University of North Carolina at Asheville) 39The Design Test: {1.2} The Site Situation The region?s topography made travel so diffi- cult that the western reaches of the Carolina?s were left virtually ungoverned. Morristown a small, remote town with an elementary log courthouse was established in 1793 as the county seat of Buncombe County. In 1795, Samuel Ashe was elected governor of North Carolina and with his nomination, the city renamed itself Ashe- ville. At the intersection of two ancient trading routes, several large land grants were subdivided into more ur- ban lots. In the census of 1800 the population of Ashe- ville was recorded as ?twentyfive free persons and thir- teen slaves? and the built environment consisted of a general store, two grist mills, a tailor, a forge, a school, and several homes. The city would quickly grow due to the increased production of the region?s raw natural resources (Chase, 2007). 2.9 Evolution of the Built Environment Periods shown: 1888, 1917, 2000 40 Matthew Biesecker 41The Design Test: {1.2} The Site Situation 42 Matthew Biesecker In 1814, the Eagle Hotel was established as the region?s first luxury hotel to accommodate travelers wanting to escape from the Deep South?s harsh summer humidity and heat. Other hotels would be established over the next two hundred years; some of which would be so massively scaled they would define and dominate the perspective of Asheville as a town. The hotels were created, as an escape from malaria outbreaks in coastal cities likes Charleston and Savanna. They would also act as a place of natural relaxation for people of great wealth whom would have been accustom to the smoky, industrial cities of the Northeast. This established the areas two perpetual attractors: health and travel, which are still the city?s two largest revenue generators today (Chase, 2007). The terrain of Stony Hill has been altered sev- eral times throughout the last couple hundred years. The first European American use of the site was as a Civil War Battery, which was influenced by the sites high elevation. This elevated situation gave influence to the site?s next use as the one of the era?s great southern travel destinations, the Battery Park Hotel. 2.11 1890s Test Site Section If compared to the 2010 Test Site Sec- tion, the over seventy feet of soil that was removed of the last two hundred years is noticeable.

The city became remote, much like it was prior to early 1800s. When the railroad was replaced in 1880, the form of the built environment became much as it is in today?s landscape. As the transportation networks from cities like Augusta, Georgia and Charlotte, North Carolina to Asheville were improved, outside investors and tourists brought their city?s artistic sophistication and architectural styles to Asheville. This created an urban style unlike anything else in the southeast. This style was a unique blend of secluded rural life and the sophistication of a large Southern metropolis. This distinctive fashion became known as the ?Asheville Style? and still exists today (Chase, 2007).

(Map courtesy of the University of North Carolina at Chapel Hill) 46 Matthew Biesecker From the mid-1880s until the Great Depres- sion, Asheville?s landscape was profoundly altered by the dreams of four wealthy titans: George Pack, Fran- klin Coxe, George Vanderbilt, and E. W. Grove. These dreams were interpreted by the world-class archi- tectural talents such as Richard Sharp Smith, Rafael Guastavino, Richard Morris Hunt, and Fredrick Law Olmstead. These architectural achievements exist to- day due to the interesting financial situation the city of Asheville was in between the Great Depression Era and the mid-1970s. In the 1920s, the development of the Grove Arcade and the present-day Battery Park Hotel reduced the height of Stony Hill by 70 feet (over 100 feet has been taken in the site?s history). Much of the site is now devoted to automobile parking, which was the most profitable use for the land in the 1970s (Chase, 2007). 2.14 Stony Hill Soil Removal (Image courtesy of the University of North Carolina at Asheville) 47The Design Test: {1.2} The Site Situation 2.15 Construction of The Grove Arcade (Image courtesy of the University of North Carolina at Asheville) 48 Matthew Biesecker Unlike many other Southern cities, Asheville did not default on its debt from the Great Depres- sion. The debt payments, along with the national post World War II migration to the then newly cre- ated suburbs, caused Asheville?s center city to dete- riorate. Droves of important stores and businesses relocated to the suburbs to take advantage of the cheap land. This movement grew exponentially; when one store left, several others followed. His- torical buildings in the city?s center were either per- severed because no new building use was needed or the buildings were completely demolished to ac- commodate the most profitable use for derelict lots, the parking lot. 2.16 2010 Test Site Section (Opposite) 2.17 2010 Test Site Figure-ground Pictured is the Battery Park Apartment (fore- ground) and the Grove Arcade (background). (Photograph courtesy of The Univsersity of North Carolina at Asheville) 50 Matthew Biesecker The debt from the Great Depression was not paid until 1976. This was a monumental event for the city and signaled a slow reinvestment into the center city of Ashe- ville. Several projects of this period created strong civic compassion for historic reservation and established the hip, eccentric atmosphere, for which Asheville is known. This project?s included landscape architect John L. Lan- tzius?s renovation of 17 vacant buildings on Lexington Avenue, which were modeled after the eclectic neighbor- hoods of the Pacific Northwest. The Bele Chere Festival, which means ?beautiful thing? in French, was the city?s 1980?s response to the lack of activity. Today, the fes- tival generates $12.4 million for the local economy over the span of only three days. The construction of I. M. Pei?s 1977 Akzona, Inc. building created a civic apprecia- tion for historical preservation through it?s demolition of several historic buildings and its dominate location in the public Pack Square. Pack Plaza and Pack Place were ur- ban renewal and development responses to the Akzona, Inc. building. Pack Plaza restored many cherished build- ings and Pack Place established new museums and civic amenities. The renewal of Haywood Avenue and Wall Street was the first successful redevelopment project that used Federal funding. 2.18 Significant Events in Asheville?s Built Environment 1976-2010 (From top-left to bottom-right) 1.)

These goals includ- ed generating revenue for the local businesses, building interest in properties adjacent to the site, and creating a space that is public in nature. It was simulated that when these goals were presented to the Asheville city officials, they were deemed appropriate and related to the desires they had for the space. Although skepticism surrounded the decision to use the selected design methodology, the city officials allowed it to be used. Based on the information gathered from the his- torical and contextual study and the presentation to the city, the design goals for the first design cycle where established. These goals are as follows: 1.) to create a publicity among the inhabitants of the site in order to generate interest, support, and ideas about the future of the site, and 2.) to create an environment conducive to restoring the urban web around the site to it?s pre- 1970s function in order to bring pedestrian locomotion to the site. These goals essentially strive to give people knowledge of the project and move pedestrians to and thorough the site. Publicity was obtained in a variety of commu- nicative methods: the Internet, word-of-mouth, visual communication, etc., all of which relayed the message of what, why, and how this project?s intended to con- struct. Most of these publicity generators also recorded feedback from the site?s inhabitants. For example, the Internet proved to be a strong tool because it not only communicated information about the project, but re- trieved information as well. The accessible nature of the blog, the websites, and the e-mail address created for the project, allows someone the opportunity to reflect on how they directly respond. Although meetings and postings were used, they did not seem to produce the well thought-out and comfortable responses of the one generated on the Internet. Meetings were held with lo- cal investors, local organizations, local businesses, and local homeowners. There were also several meetings that were held on the site to help generate interest in the 2.23 Publicity Poster Design These posters, along with other media, were created to generate excitement and feedback for the project. 55The Design Test: {1.3-1.6} Publicity and Pedestrian Connectivity project. Publicity was generated for several reasons. First, it allowed the public to be aware of the changes that were about to happen on the site. Second, it al- lowed a greater amount of direct feedback to be collect- ed because people understood what was being asked of them. Lastly, the reason publicity was needed was because it allowed a more realistic prediction of how the site would function in the future. If the holistic project goals were to be obtained, a much more diverse crowd would be present on the site than was in the existing conditions. These reasons for why publicity is important is also the basis for how the success of the calibration was assessed. If the calibration is judged on whether or not it created publicity that generated interest, support, and ideas for the future of the site, the calibration will be viewed as a successful. However, the calibration did not create a depth of rich interest, support, or ideas. This could be due to the relatively short time-span be- tween the beginning and the end of this design phase. Because the publicity did complete its goal, although more could come from it, the tactics used in creating publicity should continue. 2.24 Representation of First Direct Feedback Responses This graphic shows the uncertainty of the inhabitants during first phase of the project. It also shows how the feedback was typi- cally segregated in to what was deemed desired and not desired. 2.25 Summer Night Movie and Meeting Events that showed alternative ideas for the site became a breeding-ground for creative thinking among the inhabitants. 58 Matthew Biesecker Two calibrations were installed in the site?s sur- roundings to help improve the pedestrian conditions to and through the site. These calibrations were installed on the Flint Street Bridge, which spans Interstate 240, and at the intersection between the site and the Ashe- ville Civic Center. The Flint Street calibration?s goal was to cre- ate safer and healthier pedestrian condition for daily commuters from the Montford neighborhood. To ac- complish this, focus was put on the existing conditions of the bridge. It was observed that people walking the bridge tended to stay to the outside of bridge because of automobile traffic in the bridge?s center. This causes the pedestrian to then look downward towards the in- terstate below. A series of planter boxes were placed in the gutter of the bridge to create a physically and physiologically safer experience for the pedestrian. This caused the pedestrian to shift towards the center of the designated pedestrian path. The planter boxes did not interfere with traffic patterns of automobiles. Hanging planters were placed on the outside of the bridge to de- ter pedestrians from looking downward. This encour- aged their perspective outward to the distant mountain view. Planter boxes proved to be a cost effective an- swer because they were created from recycled material from the abandoned industries located along the French Broad River. 2.26 Montford Context Map Red arrows indicate the pedestrian move- ment from the Montford neighborhood. This is needed if the urban network is to function at its most efficient. The test site is indicated in yellow. 2.27 Existing and Proposed Flint Street Bridge Sections The section to the left describes how the automobile traffic on the bridge shifts the pedestrian to the outside of the bridge. The section to the right shows how placing an object in the bridge?s gutter can shift the pedestrian to the center of the path. 59The Design Test: {1.3-1.6} Publicity and Pedestrian Connectivity 2.28 Flint Street Bridge Calibration 2.29 Process Drawings of Flint Street Bridge Calibrations 60 Matthew Biesecker 2.30 Flint Street Bridge Calibration Notice how the publicity and feedback mechanism is integrated into the Flint Street Bridge calibration. Also, note how the planter boxes allow the gutters to col- lect storm-water and road debris. 61The Design Test: {1.3-1.6} Publicity and Pedestrian Connectivity 2.31 Flint Street Bridge Calibration These overhanging planters attempt to create a reflection of the vegetative over- hangs, which are common in the higher elevations of the Appalachian Mountains. 62 Matthew Biesecker The Haywood Intersection calibration essen- tially attempted the same technique used on the Flint Street Bridge. A high volume of intricate traffic patterns created uncomfortable pedestrian patterns for people crossing the Haywood, Flint, and Page streets. In this case, no objects could be placed in the gutter, only on the raised automobile traffic dividers. It was hypoth- esized that if an object could be placed between the pedestrian and the intersection?s automobile traffic, pedestrian conditions would improve by making the pedestrian feel and be safer. Because the calibrations used recycled materials, cheap plantings, and were placed in a delicate manner, the city used very little re- sources compared the cost of most the top-down land- scape architecture projects they fund. The assessment of this calibration is based not only on its ability to return the site?s pedestrian network back to a pre-1970s function, but its ability to increase the amount of pedestrian traffic moving to and through the site. An increase in pedestrian traffic amounts, if correctly adjusted to external factors, could be seen as a success. If the amounts of pedestrian traffic were to decrease, the direction of the next design would change. The Flint Street Bridge calibrations generated a higher rate of pedestrian traffic and caused no other major is- sues. The Haywood Intersection calibrations increased the amount of pedestrian traffic slightly, but also cre- ated conflict with automobiles. This major design flaw caused the calibration to be removed. 2.32 Process Drawings of Haywood Street Calibrations 2.33 Existing and Proposed Haywood Street Sections The section to the left leaves the pedestrian exposed to pat- tens of automobile traffic.

The circles indicate pedestrian origins, the squares in- dicate pedestrian conclusions, and the lines indicate the location of pedestrian move- ment. 66 Matthew Biesecker {2.3-2.6} THE MARKET AND THE LEDGES April 2012-November 2012 Based on the information found in the first feed- back loop, a new design goal can be created. Although the amount of pedestrian traffic increased, most of the traffic in the site was based on larger patterns of pe- destrian traffic that traversed the entire city. In other words, the site was full of pedestrian connections, but contained few nodes. Although the site could be used as infrastructure for pedestrian traffic, it was predicted that the site could act as both a node and a connection. This is evident in the ideas generated by the site?s in- habitance in the first design phase. Therefore, the goal of this design phase was to create an attraction on the site that addressed the patterns found in the inhabit- ance desires, while not completely altering the existing function on the site. It is important to not vastly change the site because: 1.) the site?s inhabitants are concerned about the decrease of automobile parking and 2.) it is not possible to collect and reflect upon data if the de- sign is completed in one phase; multiple phases allow a subtle growth of uses. To create an attraction, patterns of direct feed- back were examined. These patterns of direct feedback included: 1.) the desire to have an alternative to the high priced food and produce sold in the local area, 2.) concern of the space being loitered by the areas large homeless population, 3.) a space to relax, read, and reflect, and 4.) a place to hold events of varying sizes. With these ideas in mind, a series of strategi- cally placed steps, terraces, and ledges were installed. This created areas to rest and relax, while also creating a space to hold events. The main attracting element was a market which was held daily between the hours of 6am-6pm. The businesses that participated in the market consisted of several small local enterprises that had struggled during the economic recession. Rules were created that established a daily rotation of busi- nesses on the site. This created an ever-changing shift of businesses, which allowed the local inhabitants to ex- perience new foods and products on a daily basis. This became very popular with the local inhabitants based on the direct and indirect feedback received. It also created higher sales for the struggling businesses be- cause they reached a previously unattained client-base. Sales also increased due to the low cost of space retail, because it decreased the price of products being sold. This satisfied the local inhabitants who wanted lower priced goods in the area. 2.37 Process Drawings of Market and Ledge Calibrations 67The Design Test: {2.3-2.6} The Market and the Ledges 2.38 Market Calibration Section A series of steps creates an elevated terrace that is used for a daily market. 2.39 Ledge Calibration Section Ledges create spaces to sit, read, relax, watch other people, etc. 2.40 Market and Ledges Calibration Notice the diversity of uses from the calibrations that were installed.

In this phase, a paradox arose when the feedback indi- cated conflicting desires. This conflict originated from the underlying desire to have the space still function as a automobile parking lot. Animosity cannot arise from the inhabitant?s decision to still want to the site to function as an automobile parking lot. This is because it is built on the collection of decades of urban patterns adapting to the space functioning as an automobile parking lot. The goal becomes figuring out how to give the inhabitants the opportunity to use the space as they want, while the space is still used as an automo- bile parking lot? For whatever reason, the site?s designated space for automobile parking has been slowly decaying. Cracks split the concrete, dividing the yellow lines that indicate parking spaces into beautifully broken shapes. Some of the cracks are large enough to be considered a walking hazard and others are small and intricately spreading. If this fractured surface is viewed as a design opportunity, an interesting ground-plane can emerge. Previous feedback showed a strong desire for a public open space that could be used for events, sports, relaxation, and summer night movie screenings. Due to the slopping surface on the site, a flatter ground-plane is needed if many of these actions are to be preformed on this site. Therefore, infill was brought to the site and distributed above the parking surface. Soil was placed until it reached the height of the ledges that were in- stalled in the previous design phase. Afterward grass was seeded and was allowed to grow into the cracks of the concrete. This created a softer, flatter surface than previously existed. The reaction to the design by the site?s inhab- itance was astonishing. Although it was never stated that automobiles could not park on the calibrated sur- face, the amount of automobiles parking in that area de- creased. The intention of the design was to allow park- ing because it only occurred during the daytime. This would have allowed events space in the nighttime when no automobiles were present. The recorded reaction after the calibration of the simulation was that only a few cars would park on the surface leaving it open to other uses 24 hours a day. The reaction to a 24 hour un- programmed open space was also astonishing. Instead of the space functioning as the previous feedback loop indicated, the space became much more under-utilized than predicted. The uses people stated desire for in this space was not emerging even though it had been cre- ated. Of course some people did use the space, but not in the manner or amounts previous envisioned. 2.44 Ground-plane Transformation The transformation from broken concrete to a flat lawn is symbolic of the approach taken in this project?s design methodol- ogy. The gradual transformation for the existing to the desired. 75The Design Test: {3.3-3.6} Topographic Transformation 2.45 Existing Ground-plane 2.46 Ground-plane Calibrations 2.47 Topography Calibrations The calibration was much less popular with the site?s inhabitants than originally projected.

The calibration also left a void in the reflection of feedback such as the desire to have an event space and a space to participate in sports. After a period of recording data on the direct and indirect feedback of the site?s inhabitants, it was found that people neglected to use the space as determined in previous feedback be- cause of the limited size of the space and other climatic issues. Therefore, the goal of this design phase was to determine it?s limitations of the site and then reevaluated its possibilities. Even though there was a demand for the site to be come a space conducive to sports, the size and slope of the site limited its possibilities of fulfilling that desire. Because of this, it was concluded that the de- sign should focus on enhancing the other ideas gen- erated by the site?s inhabitants, such as the desire to have a place to relax, reflect, read, view and be viewed by other people, and as a place to reinforce pedestrian locomotion. This reassessment led to a design calibration that attempted to create microclimates based on the ex- periences people desired to have. This calibration was accomplished in two sections. First, a series of Flow- ering Dogwoods were planted to create a microclimate underneath and around its canopy. An intimate space was created underneath the canopy that allowed people a softly shaded space to read and relax. These trees also created barriers along the site which divided the site into smaller spaces. The second calibration was the planting of a native pine near the high-point of the site. The pine tree attempted to create shade for the western half of the site, while also acting as a attraction. The pine acted as a reflection of the past elevation changes. This is based on the image of the knobs excavation during the 1920s, which showed a quarry like landscape with one remaining pine atop a struggling mound of soil. The maximum height of the pine at maturity would reflect, almost exactly, the elevation of the knob prior to the revolutionary war. 2.50 Process Drawings of Vegetation Installation Calibrations 2.51 Vegetation Installation Calibration Growth of trees indicated by different shades of pink. 81The Design Test: {4.3-4.6} Vegetation Installation (Top Left) 2.52 The Land of the Sky Booklet Cover (Image courtesy of The University of North Carolina at Asheville) (Bottom Left) 2.53 Stony Hill Soil Removal (Image courtesy of The University of North Carolina at Asheville) 2.54 Pine Tree Calibration The pine tree calibration is a symbol of past landscapes. 2.55 Vegetation Installation Calibration The pine tree calibration is a symbol of past landscapes. 84 Matthew Biesecker 85The Design Test: {4.3-4.6} Vegetation Installation 2.56 4.6 Direct Feedback Distribution 2.57 4.6 Pedestrian Indirect Feedback This feedback study indicates a morning study in yellow, a midday study in orange, and an evening study in red.

Over this time, recession that hindered the city?s resources to invest into public space ended, businesses established them- selves in nearby vacant buildings, and private investors constructed several multi-use high rises adjacent to and in the vicinity of the site. The placement of new struc- tures reduced the site?s capacity to be used as parking for automobiles. Because the space and the inhabitants desires for automobile parking on the site decreased, Page Avenue was no longer required. Therefore, the city decided to remove the street and grant it to the pub- lic space. This along with slowly evolving changes the site?s context lead to a new design phase. One of the main goals of this design phase was to retain the pedestrian patterns that accumulated along Page Avenue for the duration of the project, while still reflecting the new changes in the site?s context. This was accomplished by leaving the existing pathway which were heavily used by pedestrian traffic. This cre- ated a unified site that contained layers of pedestrian traffic patterns. Over the duration of the project, movies have been screen on a regular basis, along with the occa- sional live theatrical show, courtesy of the Asheville Civic Center. The screen that was used for movie pro- jections became worn and needed replacing due to the frequency it had been used. This situation created the opportunity to permanently replace the screen with one of better quality. It also created the opportunity to al- low a the screen to be viewed 24 hours a day. At first, the screen showed different movies throughout the daytime and evening hours. Although this created an ever-changing show for the local inhabitants, it became overplayed and lost much of its attraction. Instead of leaving the screen unused for a majority of the day, it was connected to a two-way video feed to Asheville?s sister cities. The video feed was timed for communi- cation during appropriate daytime hours and became a popular attraction for tourist and locals. Through the digital realm, the screen extended the public space into anther public space halfway around the world. 2.58 Process Drawings of Geological Expression (Opposite) 2.59 Layers of Uses Map This map shows the pedestrian patterns that traverse the site (pink dots), the event spaces created by the calibrations (pink ovals), and the increased building front intensities (pink lines). 87The Design Test: {5.3-5.6} Geological Expression 0 60 150 300 Pedestrian Patterns Asheville, USA Valladolid, Yucatan San Cristobal de las Casas, Mexico Osogbo, Nigeria Saumur, France Karpenisi, Greece Vladikavkaz, Russia 89The Design Test: {5.3-5.6} Geological Expression The demand for a public art installation on the site grew over the duration of the project. To reflect this desire, a ground-plane was installed that record- ed movement by signaling small lights placed within the surface. The ground-plane could be programmed to react to pressure in an infinite amount of ways, the first tested being a watercolor spat. This also became a popular attraction for both tourist and locals and also recorded indirect data for future feedback. Three pools were created to reflect the desires of the site?s inhabitants to include a dog wash and a hot springs. One pool was located near the highest eleva- tion of the site, one at a middle elevation in the center of Page Avenue and the other was located near Haywood Avenue at one of the lowest elevations. The two most elevated pools were gently sloped to allow for ease of accessibility. The lower pool had been created to allow a slow movement of water to circulate. Between the lowest pools, a variety of boulders were placed to create a space for sitting within the pathways of heavy pedes- trian traffic. These boulders were also a reflection of the past state of the site when it was termed ?Stony Hill.? Feedback on this collection of calibrations was neither propelling or direction altering. The feedback recorded showed the inhabitants to be content with the calibrations, although still slowly generating unique ide- as. These new ideas, as the ones before it, were based on the emergent phenomena found in the interaction of the site?s inhabitants and their interaction with the cali- bration. Based on the feedback, it was decided that a larger design calibration would disrupt the patterns that have been and are being established on this site. From this point forward, it is predicted that the desires of the site?s inhabitants will remain level, needing many small calibrations, but very few calibrations of comparable size to the five previous.

CONCLUSION 100 Matthew Biesecker CONCLUSION After the design test was completed, the thesis and design test were assessed by their predetermined goals. The thesis was also criticized by a panel of crit- ics from the Auburn University School of Architecture, my collogues in the Auburn University Master?s of Land- scape Architecture Program, and myself in order to find the strengths and weaknesses of the thesis. This con- clusion will be based on seven post-design test ques- tions that are a culmination of the questions used to assess and critique the thesis. The questions are as follows: (1) did this thesis establish a vocabulary suit- able for the discussion of the application of the theory of emergence to landscape architecture? (2) was the de- sign methodology emergent in the process of designing a public urban space? (3) did the design test create an emergent design methodology for creating public urban spaces? (4) did this thesis generate a foundation for fur- ther discussion on the subject? (5) what ideas were de- veloped in this thesis that could be furthered? (6) how could this project be improved? (7) what might be the future developments in the application of emergence to the craft of landscape architecture? This thesis established a vocabulary based on the research I conducted using several sources. The vocabulary created covered terms that would be used in this thesis: rules, interactions, complexity, complex systems, organized complexity, public urban spaces. Other terms will need to be explored and defined if this thesis continues into other sub-fields of landscape ar- chitecture. Also, new methods for detecting emergent behavior in the built environment will have to be created in order to relate this thesis to other sub-fields in land- scape architecture. Although the term emergent is still elusive, the design methodology created in this thesis was found to have emergent behavior. This should not be mistaken as a perfect emergent process. Due to the material na- ture of landscape architecture, I doubt a truly and ho- listically emergent process, as we would compare it to other disciplines, will ever evolve. This does not mean we should not seek to create a design methodology that has emergent behavior; only that perfection might not be attainable. The design test echoed the success of my at- tempt to create an emergent design methodology. The design test, if viewed at the scale of single phase, is not emergent, except maybe for inhabitant?s responses to the design calibration and the designer's response to the analysis. If the design test is viewed at the scale of the entire project, it is emergent. This is possible be- cause it increases organized complexity throughout the life of the project, uses feedback loops that indicate the patterns of desires and reactions of the site?s inhabit- ants, and the design?s form is not predictable by exam- ining one individual. Further discussion on this thesis should arise because only one design test was used, which could be limited by its test location?s place and time, my re- actions as a designer, and the nature of simulating the test. If another person using the same test parameters and the same design methodology replicated this same test, I believe a completely different process and design would materialize. This, I believe, is the freedom in the project to still be a designer. This interpretation is the project?s design. This project had several ideas that could be used in other studies. Most of the ideas that could be furthered are individually no different than the ideas of others in the field of landscape architecture. What is dif- 101Conclusion ferent about this project is how these ideas are related. This relationship of ideas is what should be developed further in other academic inquires. The following are individual components of this project that could be fur- thered: (1) the feedback loops or mechanisms, (2) the cyclical nature of the design procedure, and (3) the ap- plication of emergence after the design has reached its calibrations/fulfillment pinnacle. Several components of this project could be improved; three of which will be identified and alterna- tives for the improvements will be attempted. The first component that could be improved is the simulation of the design test. Because the project was a simulation of what might occur in real life, concern arises about the authenticity of the simulation. This could be improved in several ways: (1) test the design methodology in a real- world setting, (2) create a larger and more diverse base of people to simulate the unpredictable feedback, and (3) take more time to test the simulation against case- studies that are similar to each of the phases of design. The second component that could use future improvement is the functionality of the feedback loops. During the multiple presentations of this project the same question arose, ?on what basis are the feedback loops assessed?? This question was answered by stating that the analysis that brought on a design goal design also created the basis for assessment of the feedback. The design?s goal created a means for testing the success- fulness of the design. I do not have an alternative basis for the feedback loops, but it is accepted that this is not completely acceptable answer. But the answer is not completely wrong as well. Each person who tests this design method could have their personal interpretation of what the basis should be. The third concern found for this project is the lack of control a designer would have in the design of the project. It is the nature of the project to allow certain controllable reactions to take form in the design; there- fore the designer cannot have complete control. If the design that emerges is not to the designer liking, then this design methodology may be discarded and another methodology be used. The design cannot be completely condemnable, even if it is aesthetically unpleasing, be- cause the form of the project is based on the responses of the individuals who inhabit the site. This question is the essences of the top-down/bottom-up design para- dox, thus cannot be answered completely by the current state of theoretical understanding in landscape archi- tecture. 103Conclusion (Opposite) 3.2 Evolution of the Site This graphic is an account of the simu- lated evolution of the design test. Notice the gradual accumulation of landscape architecture elements on the site over the duration of the project. The phases were as follows: {1.3-1.6} February 2010-April 2012 {2.3-2.6} April 2012-November 2012 {3.3-3.6} November 2012-July 2013 {4.3-4.6} July 2013-August 2023 {5.3-5.6} August - APPENDIX I-V 106 Matthew Biesecker APPENDIX I: DEFINING EMERGENCE It is important to understand that similar to most words, which can be expressed in both the forms of a noun and a verb, the term emergence has several inter- pretations and understandings. For the purposes of this thesis it is important to define emergence as it relates to the design process of creating public urban spaces. Essentially, emergence is the complexity cre- ated from the patterns of behavior on a lower scale. An emergent system is a bottom-up system, which is a complex adaptive system that displays emergent be- havior. Its adaptive ability comes from a multitude of relatively simple lower-level elements and not a singular higher-level entity. Depending on the definition in use, several different components form its meaning. In some definitions the lower-level entity that generates higher- level complexity is interaction, while other definitions use rules. In this thesis, interactions and rules will be used separately and in conjunction in order to generate organized complexity. Ants and the structures they create are com- monly used as examples to explain the theory of emer- gence. The operations of an ant colony will also help to explain four commonly used terms: rules, interactions, complexity, and complex systems. Keep in mind, I do not think of humans as ants, but merely want to use them as an aid for understanding fundamentals of emer- gence. Despite the title ?queen ant? studies have shown that there is no ultimate leader, planner, or ar- chitect in the structural development of ant colonies or the structures known as anthills. The form of an anthill is designed by the incomprehensible actions of the en- tire ant population. The theory of emergence has identi- fied the designer as emergence itself. To describe how this design without a designer takes place, the narrative should begin at the lowest-scale of ant colonies and move towards the highest-scale. Ants communicate by emitting chemical sig- nals, which express approximately twelve functional emotions. Ants, not being able to understand the world outside of their local perspective, think and act on their local scale. This behavior is based on the rules of ant communication and understanding. When an ant?s de- sires are regulated by these simple rules the controlled unpredictable behavior of an individual creates the pat- terns of higher-level complex systems. Therefore, rules, in the sense of emergence, are not used to regulate in- dividuals from their desires, but to regulate a complex system from becoming chaotic. Rules are what sustain organization in organized complexity. The rules allow ants to communicate and to in- teract with one another at their local scale. These inter- actions, when viewed at an individual level may seem and might be random. Communication signals may indi- cate the desire to exchange food particles, create alarm, or show attraction; however, if the signals are viewed at the next highest-level, patterns of the ants desires as a whole will emerge. This is how interactional emergence functions. Many seemingly random interaction over a duration of time generates the patterns found in com- plex systems. Interactions breed other interactions in the same way that when ideas are exchanged it usually promotes the creation of other ideas. If the entire ant colony sequence is understood, the rules of ants create the interactions of ants, which create trails and ant infrastructure, which then cre- ate the entire ant colony; organized complex systems 107Appendix I: Defining Emergence arise from the individuals. Complexity, although often thought of as confusing or incomprehensible, is simply the composition between many interacting parts. Com- plex systems are systems composed of interconnected parts that exhibit behaviors, which are not obvious from the properties or behavior of the individual parts. In the ant colony example, complexity would be all of the ants interacting, and a complex systems would be the colony itself. After these fundamentals are understood, ques- tions arise about how this theory can be applied to cre- ate a desired goal. These are typically questions about organized complexity. Organized complexity is the ul- timate goal of most scientific and computational appli- cations. It allows a bottom-up complexity to emerge from lower level patterns, while still having some form of control and guidance. Organized complexity is the jux- taposition of complete control and chaos. It allows an unknown outcome to transform into something useful. 108 Matthew Biesecker APPENDIX II: EMERGENCE AND LAND- SCAPE ARCHITECTURE Since the term emergence was coined in 1875 by English philosopher and literary and theatrical critic G. H. Lewes (Lewes, 412), the theory has been tested by scholars in a variety of fields including ecology, eco- nomics, mathematics, and computer science. As the theory was examined, emergence was found to be present in nearly everything and seemed as though it had always existed. As the urban realm was taken un- der examination, the results were similar to the findings of other fields (Helie, 2009, 76). But the development of the theory of emergence did not end in its applica- tion as a means to understand an existing phenomenon. The next step in its development was dedicated to the application of emergence to obtain a predetermined goal. This second application of emergence to the ur- ban realm is currently in an early state. Tom Wiscombe, an architectural designer and founder of the California- based architectural practice EMERGENT, finds that this transition to apply emergence as a means to obtain a goal in architecture is posed for investigation. ?The idea that innovation, whether scientific, techno- logical, or architectural, is a by-product of artistic chance or a result of singular genius can no longer be sustained in the 21st century. Complexity theory reveals that innovation-- the creation of the new-- is the direct result of bottom-up evolutionary processes. Science knows this; industry is learning. Architecture is just beginning to engage the con- cept. In order to move into this space of innovation, archi- tects will have to except the value of multiplicity and dynam- ic feedback over the retrograde nature of authority. They will have to accept that architecture might not be about essences and theoretical positions, but rather about ex- changes of techniques, expertise and materials in multiple industries. They will have to accept that the architecture is no longer a heroic center, but one micro-intelligence among many. They will have to let go and begin to love the swarm. New models of practice therefore might be based on dynamic organizations in which entities can operate both independently and in collectives at the same time--that is, as parts and as wholes. Parts, which are more specialized than wholes, can rarely evolve or become innovative on their own, just as a single neuron in ht human brain can never have thought. Evolution occurs in the system. Perhaps the best way to frame this discussion is through the phenomenon of emergence (Wiscombe, 2006, 59-61).? More studies are currently being conducted about the relationship of the theory of emergence to urban design and planning than the related fields of ar- chitecture and landscape architecture. It is important to understand that most of these studies being conducted use different definitions of emergence and have varying goals for its application. These discrepancies seem to be rooted in the conflicting material natures of the disci- plines: urbanism more flexible, architecture more rigid. As a variety of understandings of emergence are applied to this array of interconnected fields, a diversity of ideas about how emergence should be used is generated. Studies in urbanism typically apply the theory of emergence to cities much the same way an entomolo- gist would study ants; viewing the city as a existing phe- nomena. Urban theorists typically perceive the city as an existing whole and view objects in the city, especially buildings, as the parts. Studies often state that building design has little to do with the emergent behavior of a city and often times it is more generative of emergent behavior if the buildings are universal and mundane (Helie, 2009). 109Apendix II: Emergence and Landscape Architecture Architects tend to use the theory of emergence as a means to accomplish a design goal by applying it to the design of an object. For the most part, architects view emergence as a trendy form of morphogenesis. This application of emergence perceives an evolutionary object that has a very loose correlation to its surround- ings. Object-based perception this is what is termed ar- tificial emergence. Artificial emergence occurs when a misunderstood version of emergence is attempted to be claimed as emergence. This misunderstanding may ex- ist because the material nature of architecture does not allow evolutionary change to occur. It would probably be constructive if architects did not view emergence in an objects design, but as an evolutionary behavior that created objects and creates other objects (Wiscombe, 2006). The studies conducted in landscape architec- ture have used the theory of emergence in both a con- textual and an object-based manner. This might be due to the medial positioning of landscape architecture to its related disciplines and its material nature?s variance between the fluctuating nature of urbanism and static nature of architecture. Another reason for landscape ar- chitecture?s balanced perspective could be scaling and the current understanding of emergent patterns. These reasons could position landscape architecture to best apply the theory of emergence as a means to obtain a goal in the urban realm. The balanced nature of landscape architecture creates two main fields of thought when it comes to the application of emergence to practice: emergence before a design and emergence after a design. In this instance design is defined as the pinnacle of landscape altera- tion and the return of ?should this be of?? designated goals. With emergence before a design, emergence is viewed as a series of reactions that creates a situa- tion. Emergence after a design, emergence is viewed as a reaction to a situation. Because the urban realm is an emergent phenomenon, either approach could be used as a means of creating emergence. But only emergence before a design allow emergence to guide a design. Therefore, emergence before a design should be examined further in attempting to create a public space. However, because of the paradoxical nature of these two types of applications, it might be impossible to rely entirely on either one. Instead of viewing the ap- plications as separate, it could be more effective to use emergence before a design and emergence after a de- sign in conjunction. 110 Matthew Biesecker APPENDIX III: CHORA CRITICISM The Dutch planning, urban de- sign, and architecture firm CHORA specializes in difficult urban problems that contain many stakeholders. Cur- rently CHORA has diverged its focus to merge energy planning and urban design. CHORA?s principal, Raoul Bunschoten, is a Professor of Urban Systematics at the University of Applied Science in Dusseldorf, Germany and is the advisor on sustainable urbanism and urban energy efficiency to the German Ministry of Urbanism and Construction (chora.org). Bunschoten and students from the Berlage Institute in Rotterdam, the Netherlands developed a scenario-based design methodology that uses mostly qualitative information based on the firm?s fieldwork (Ellin, 125). CHORA and Bunschoten use a management system called the Urban Gallery to guide the evolution of a planning project. The Urban Gallery is a dynamic tool that engages stakeholders to act collaboratively throughout the duration of the project. The dynamic na- ture of the Urban Gallery is created by its diagrammati- cal master plans, which generate project knowledge through its monitoring of a fluctuating and liquid design. The Urban Gallery consists of four main phases; data- base, prototype, scenario game, and action plan (chora. org). The first phase of the Urban Gallery collects in- formation and creates a narrative for the dynamic proc- esses in a certain place and time (Ellin, 125). CHORA officially defines the database phase as ?a description of dynamic processes (chora.org). The narrative is written in a qualitative fashion focusing on four basic processes; erasure (elements taken away), origination (the emergence of something new), transformation (ele- ments that are changing), and migration (elements mov- ing through) (Ellin, 126). These processes are described in mini-scenarios, which are called ?operational fields? (Ellin, 126). These operational fields create small nar- ratives for the area along with mapping of the area?s dynamic processes (chora.org). These processes are divided into three categories: scale, impact, and in- volvement (Ellin, 126). The second phase of the Urban Gallery creates prototypes based on the operational fields from the first phase. Bunchoten defines prototypes as; ?a programmatic condition: it is an organization of the pro- grams in that case is not an object in itself, it is a device in the form of a specific architectural configuration, an organi- zational structure embedded in the architecture or urban space that links and intertwines programs in such a way as to give them dynamic properties. These lead to emergent spatial, social, political, and other developing qualities (Bun- choten, 2002, 5).? A prototype creates new conditions by inter- twining two or more operational fields based on four ac- tions: branding (symbolizing to distinguish), earth (land, water atmosphere, etc.), flow (the fluctuation of ecolo- gies, economies, hydrology, etc.), and incorporation (the calibration of political and social structures) (Ellin, 126). The third phase, scenario games, is a simula- tion and a test of possible realities. ?The dynamic proc- esses registered in the database form the raw material of the scenario games and the fuel for the prototypes (chora.org). The scenario game phase leads to the forth phase called action plan. Action plans are strategies that initiate the implementation of specific prototypes, while also ?describing the potential interrelationships 111Apendix III: CHORA Criticism between different prototypes? (chora.org). Studies I have conducted found the methodo- logical approach of CHORA?s Urban Gallery practices to be an attempt to create emergent behavior or extend ex- isting emergent behavior into the design and post-con- struction functionality of public urban spaces. Emergent behavior can be seen in certain phases of Urban Gallery including the stakeholder feedback generated by the prototypes. But as a methodology, it denies emergent behavior to affect the design?s outcome. This is due to the design process?s attempt to forecast an outcome for the unpredictable future of the site. CHORA limits the endless possibilities of a place to an ?action plan? which is essentially a time-scaled master plan. It is suggested that the CHORA design meth- odology could benefit by not attempting to predict the future, but instead be susceptible to the unknown changes that will occur. Allowing the unpredictable to enter the design process and feed it would eliminate the need for an action plan. CHORA?s design methodology could also benefit from not viewing their predictions as the controlling element, but use the design process it- self. The methodology itself could create rules to keep the project from becoming chaotic. This would also eliminate the need for the controlling efforts of the ac- tion plan. Tom Wiscombe states this susceptibleness using the terms linear and non-linear. ?The products of emergent networks are non-linear and non-predictable, which is a risk, but one with exponen- tial rewards. Linear processes will always create prod- ucts, which are calculable and applicable in particu- lar, industries, but they will never exceed their inputs. Non-linear, emergent processes create innovation and newness out of proportion to their inputs, and often ap- plications which lie outside the original trajectory (Wis- combe, 2006, 60).? Because CHORA typically works in the public urban realm, it is necessary to distinguish the firms defi- nition or goal of a public urban space. Bunschoten de- scribes public space as such; ?Public spaces must have a prototypical character; they are instruments of change for a society. They are sin- gular, they create an identity, and they must be able to stimulate the evolution of all kinds of parts of society. The singularness of public space remains a key attractor for a variety of people, events, collective expressions, programs, but what comes out constantly changes, adapts to new trends, forces, desires, and it multiplies in its adaptations over time. The use of a public space proliferates increasingly in the ways that they are used and the ways they give form to a society and its dy- namic mechanisms. (Bunchoten, 2002, 5). Bunschoten description of a public space is consistent with my own views of how a public space should perform. Bunschoten concludes that public space is an element that is both inspired by and inspir- ing to the evolution of societies. The terms ?prototypi- cal? and ?singularness? relate to the ability of a public space?s to be authentic and unique in its reflection of contextual changes. When a public space is influenced by its context?s desires, it must adapt in a manner that creates an idiosyncratic attraction that initiates more desires. In this cycle, public space can affect its dis- tinctive uses. This process, if viewed holistically and not as individual phases or cycles, is an emergent behavior. The question becomes whether or not CHORA?s meth- odology is the most effective means of achieving this ambition of public space? 112 Matthew Biesecker APPENDIX IV: ?TREE CITY? CRITICISM Tree City, the winning entry for the Downsview Park Competition, is one of the best examples of the application of the theory of emergence to the design process of a public urban space. The competition was held in two-stages: one in November 1999 and one in May 2000. Dutch architect Rem Koolhass and graphic designer Bruce Mau who entered the most unpreten- tious presentation in terms of physical interventions produced the winning team. While other teams, like James Corner and Stan Allen, tried to convince the jury on their design using a great depth of detail for the fu- ture outcome of the site, Koolhass and Mau developed a strategy that allowed the park?s design to adapt its the ever-changing contextual situation. Instead of propos- ing a design at the time of the competition, in the typical master designer fashion, they laid out a framework for a design process that was designed by the emerging patterns that were created by the individual elements that created the city. This strategy became the project?s design (Waldheim, 81). Koolhass and Mau reduced the design proc- ess into what is essentially a formula. This formula is based on the principles that urban parks are a lucra- tive investment and at the time of the competition it is impossible to understand enough about the site to successfully produce a design. From understanding those principles, Koolhass and Mau created a formula emerged that creates a design over time. The formula is written as such: SACRIFICE AND SAVE + GROW THE PARK + MANUFACTURE NATURE + 1,000 PATHWAYS + CURATE CULTURE + DESTINATION AND DISPER- SAL = LOW DENSITY METROPOLITAN LIFE (85). When the process was applied to Downsview Park it created a timeline, which listed phased interac- tions. From 2001 to 2005 the site?s contaminated soils would be remediated with a succession of vegetation. From 2006 to 2010 programmed activities would be established along with a network of pathways. These human-based interactions would be based on the ac- tions of the people who inhabited the site from 2001 to 2005. In the years between 2011 and 2015 large circu- lar planting of trees would be established in order to dis- tinguish the natural landscape elements form the human designed landscape elements (oma.eu). Tree City has been written about extensively over the last decade. The negative criticism is generally focused on how the project reduces the craft of land- scape architecture to a simple equation of pathways and ball fields. The negative criticism also heavily re- flects on how the project places an emphasis on generic elements in a field that is physically engaged in diverse systems. The project?s positive criticism includes its strategic nature and its stance on public space as a rev- enue generator (Berger, 131). This thesis? criticism of Tree City is consistent with other criticisms, but I also feel that there is relation- ship between Tree City and the theory of emergence, which could bring a different perspective on the exist- ing criticism. This new criticism can be broken into two questions; first is the formula used in Tree City emergent and if it is, then how could it be improved? Reducing the design strategy in Tree City to its essentials, the formula can be read as ?when it becomes this date, we will do this.? Because Koolhass and Mau understood that the site?s situation in 1999 was much different than it would be in 2015, they allowed the un- predictable nature of the urban form to influence their 113Apendix IV: ?Tree City? Criticism design. They set forth rules that stated certain land- scape elements will be placed based on the unpredict- able actions of the site?s inhabitants. This institutes a bottom-up design strategy. This shows that they were aware of the emergent behavior and how it currently ex- ists in low-density urban life. Therefore, I believe the placement of design elements exhibits emergent behav- ior, but the design formula lacks emergent behavior. If a truly emergent formula were to be created, the pro- grammed elements would adapt with the desires of the individuals. For this reason, the emergent ability of Tree City is regulated. This formula could function in a more emergent manner if it extended the feedback loop cre- ated in the placement of elements into the selection of elements. 114 Matthew Biesecker APPENDIX V: CONVERSATIONS AND CRITICISM: DISCUSSIONS FROM THE STUDENTS, FACULTY, AND ALUMNI OF AUBURN UNIVERSITY?S LANDSCAPE ARCHITECTURE DEPARTMENT Feedback from several presentations and doz- ens of conversations occurred throughout this study. These talks helped guide the project?s development and evolution. These discussions occurred in several differ- ent forms and sizes, but almost all of them involved the presence of the students, faculty, and alumni of Auburn University?s Landscape Architecture Department. The accumulation of a year?s worth of discussions created noticeable patterns of positive and negative criticism. These patterns were created by the same question be- ing asked consistently. Although these patterns are dif- ferent, they are interconnected by a similar and binding question. This fundamental question asked, ?On what basis is a design made?? This is an account of what this question is asking, how it emerged, why it?s important, and how it has answered. What does it mean to question the basis of a design? Essentially, this is questioning what is the ra- tionale or logic behind the decisions that lead to the creation of a design. What made the designed product and what it is? Of course, this could ask several differ- ent variations of the same question depending on the design under consideration. In order for this thesis?s design test ask this question, a further definition of what this question is asking is needed. If this question were inquiring the rational be- hind design maneuvers of this thesis, it would be logi- cal to apply the question to the part of the project that requires a rationale. This could be established as the transformation from recording feedback data to the creation of design goals that reflect that data. This is the analysis phase of the project, and it is the backbone of the feedback loop. In this section of the feedback loop, the landscape architect has to interpret the infor- mation found in the responses of the site?s inhabitants. To reduce this problem to a formula, the basis would be the information or data recorded as a response from the site?s inhabitants, and the ?rationale? would be the landscape architect?s interpretation of the data. At the surface, this formulaic expression seems to answer the question, but the answer had a much deeper under- standing that needed to be further explored. When this study was in its early developmen- tal stages, several instances arose where the audi- ence could not perceive the feedback loops during the presentation. This was due to poor oral and graphic representations of the information found by the feed- back mechanisms. This poor representation led to a misunderstanding of not only the information found by the feedback mechanisms and what mechanisms were being used, but the function of the mechanisms them- selves. As the project advanced, better visual and au- dible representations were constructed. This created a better understanding of the information found by the feedback mechanism, but the questions of why it is im- portant and how it is used remained. The main significance of the feedback loops is that it allows the possibility for the site?s inhabitants to react to a situation and then have that reaction reflected in the design. This reflection of the site?s inhabitants de- sires is what divides this design methodology from top- 115Appendix V: Conversations and Criticism down methodologies, which rarely offers the chance for the site?s inhabitance desires to be reflected in an adap- tive manner. The feedback is also what makes this de- sign methodology different than CHORA?s approach or the approach found in ?Tree City.? If the feedback were not taken into consideration, the adaptive quality of the design methodology would diminish, if not completely be removed. Questioning how the feedback is used is very interesting because it cannot be answered universally. The type of response a landscape architect can give is based on the type of feedback data recorded. For in- stance, a design that yields feedback that is qualitative in nature will produce an evaluation that uses qualitative methods. If a design produces feedback that is quanti- tative in nature, the feedback data is measurable, there- fore able to be reacted to in a quantitative manner. With that stated, I believe the feedback pro- duced in the design test of this thesis is interpreted by the person controlling the project?s process. That is, of course, only if the landscape architect is willing to be humble and allow the feedback to dictate the outcome of the project. Although the landscape architect is sup- posed to reflect the desires of the site?s inhabitants, an injection of professional responsibility has to underlie the landscape architect?s reaction to feedback data in order to keep the design in check. In other words, someone has to regulate the ideas in order to respect the goals of good urban form. This explanation may seem as though it gives responsibilities to the landscape architect that are broad and undefined, but I believe this is the section of the feedback loop where personal creativity and grassroots programming can converge. For example, if this design methodology was tested using the same site, but with different landscape architects, different designs would emerge. This is because each landscape architect would interpret what their responsibilities are differently. This seems to be a unique position where the program- ming of a site is bottom-up and the design reaction is top-down. This rationale also has many negative criticisms. The main critique is the looseness or openness of the landscape architect?s ability to decide what feedback is important. Ironically, this is the same element of the feedback loop that hinges the entire project together, allowing a unique design based on the landscape ar- chitect?s interpretation. This criticism is both functional and ethical in nature and should be answered with fur- ther research. But for now, it should be concluded that the programming in this project is bottom-up and the means to address the programming is top-down. In conclusion, the basis or rationale behind the design is located within the feedback. The type of in- formation that can be recorded as feedback determines the type of feedback data produced. This then dictates the type of assessment that can be given, which guides the goals of the design. Essentially, the type of informa- tion that can be extracted from the situation determines the type of design. 116 Matthew Biesecker BIBLIOGRAPHY Asheville and Environs The Built Environment.
