The goal is to develop architectural and open space improvements which would help create a vibrant academic cluster in which to house a greater range of teaching, research, living, and recreational activities than are served by the existing campus. This expansion of architecture and infrastructure would be carried out in a way which reduces the site’s vulnerability to storm events and climate change while enhancing ecological function and the site’s interaction with adjacent natural areas. 1 1.

Resilience ethical practice Tropical Coastal Development and Ecosystem Health W hile architects have contributed in many ways to the richness of contemporary culture, we have also been complicit in the transforma on of living landscapes into ecologically and socially depauperate environments, nourishing neither human nor non-human life. The AIA code of ethics specifically states that architects have an obliga on to prac ce in an ethically and environmentally responsible manner. (AIA Code of Ethics, Canon VI) In his speeches to the design community, the architect Bill McDonough defines negligence as proceeding with something we know to be harmful. To this end, we as a profession have been negligent in our obliga on to design for a physically, socially, and ecologically sound future. Nowhere is this more evident than in resort ci es like Miami, where the natural resources which spurred development have been so quickly and drama cally altered. There is no way back. However, this thesis proposes a way forward which allows for the dynamic evolu on of both human and natural habit mediated by a core structure which is both stable and resilient. 4. Miam Art Museum landscape proposal, author 3. Shanghai new town concept, author urbanism and “nature” Postmodern ecological theorists have wri en extensively about the ar ficiality of our concept of “Nature,” meaning everything which exists outside the human sphere. In The Social Crea on of Nature, Neil Evernden explains how this construct is so deeply embedded in our culture that it is difficult to see. Western religions are based on the assump on that humans exist outside or above the rest of nature. Yet the system-oriented founda on of modern Ecology is increasingly influencing the way we look at humans’ place in the world. Ecologists are increasingly recognizing the need to accommodate human settlements into conserva on planning, while architects and planners are giving increasing priority to ecological func ons as criteria for design. Coastal ci es like Miami present an especially important challenge. The coastal zone represents the margin between landscape and seascape, and as a linear element represents a very small percentage of terrestrial or marine habitat. Through physical form, chemical characteris cs, and species interac ons, coastal zones are among the most cri cal and biologically produc ve places on earth. They are arguably the most threatened. 3 resilient community As urban designers begin to think about natural systems as a metaphor for human development, vocabulary from the biological sciences has been adopted by architects, and taken on new meaning. Conserva on biologists have been interested in the idea of resilience – that is the capacity of a given ecosystem to maintain its essenƟal characterisƟcs despite stressors including changing environmental condiƟons. Stressors can be events of short dura on and high intensity such as fire or hurricane, or long term events such as the aging of a mature forest canopy. The concept of resilience has also been applied to human communi es, and implies durability of a range of elements from economic and social stability to ability of infrastructure to withstand the pressures of climate change. This thesis suggests that human communi es are inseparable from the natural communi es in which they are set. Responsible deve opment should consider the resilience of both. 5. community workshop, author responsible development Humans, perhaps the planet’s most impac ul terrestrial species, have long exploited the richness of the coastal zone, for localized resources such as fish but also as a point of access to the larger marine environment for resources and transport. Coastal se lement thus originated as a pragma c solu on to the habitat problem of a terrestrial species dependent on marine resources. As a species, we are s ll heavily dependent on the produc vity of marine ecosystems. However, se lement and habita on of the coastal zone is no longer primarily driven by nutri onal or economic necessity. The majority of coastal development is now driven by humans’ aesthe c preference for the coastal zone. While this preference may be biological in origin, we now choose to live there because we find it pleasurable – for the climate, breezes, recrea onal swimming, and access to expansive views and light. 4 While the prac cal necessity of coastal living has decreased over me, the extent of se lement, and its impact on ecological func on has increased. Like all species, we are dependent on the ecological health of this zone for our own well being. If we choose to build and live there for aesthe c reasons, it seems that there is a moral impera ve to make our presence in the coastal zone as posi ve as possible from an ecological perspec ve. At the same me, coastal development contains some of our most culturally important urban fabric. From an ecological standpoint, resilience is o en associated with biodiversity. The more diversity in a system, the more its essen al elements overlap, creating redundancy which allows for con nuing func on of the system if a par cular component or species is under stress. For example if a cold winter causes a certain plant to bear no fruit, plant diversity will increase the probability that there will be an alternate food source for fruit-ea ng species. Resilience is also associated with abundance. If a stressor causes a certain level of mortality in a species, a larger popula on will increase likelihood that a minimum viable popula on survives. Resilient design incorporates some of the same principles. For example, a resilient building would be designed for natural ven la on lessening dependence on centralized climate control, a resilient economy would contain a range of produc ve ac vity, lessening dependence on any single sector. 2. Site History virginia key development history U nivesity of Miami’s Rosens el School of Marine and Atmospheric Sciences (RSMAS) occupies about six and a half acres along the southwest shoreline of Virginia Key. An island of about 860 acres, Virginia Key is located in Biscayne Bay east of Miami and immediately north of be er known Key Biscayne (figure 1). The island is connected to mainland Miami and Key Biscayne by the Rickenbacker Causeway, a county toll road opened in 1947 to provide public access to the ocean beaches of Key Biscayne. While Miami grew rapidly as a result of residen al and tourist development, Virginia Key retained large areas of undeveloped open space, while the balance was divided into large parcels developed for public or ins tu onal purposes.

The ar ficial lagoon to the north of the stadium separates the recrea onal zone along the causeway from the natural and infrastructure uses to the north. Situated at the south end of Virginia Key, the RosensƟel School is part of a somewhat accidental complex of marine related research ac vity. Located across the Rickenbacker Causeway are regional research centers for the NaƟonal Oceanic and Atmospheric AssociaƟon, and the NaƟonal Marine Fishery Service. Also located on the east side of the causeway is the Mast Academy, a Miami-Dade magnet high school for marine science and technology. Miami Seaquarium is immediately adjacent to RSMAS on the north. Opened in 1955, the facility has regional appeal, but has not kept up with other public aquaria such as Monterrey which have invested in improved facili es designed to emphasize educa on and marine research. 3.

The north end of the island is occupied by the wastewater treatment plant and the remainder of a municipal land-fill. The land-fill has now been capped, and is now primarily covered with scrub forest. The ac ve wastewater treatment plant is screened by a forested strip facing Virginia Key Beach Park. The historic park served African Americans from 1945 un l desegrega on of the other municipal beaches. The park was closed in 1982 and re-opened in 2008. The current design emphasizes the park’s history while allowing for contemporary recrea onal use stressing low-impact beach ac vi es and respect for the site’s ecology. To the west of the treatment plant is the island’s largest remaining patch of mangrove forest. The eastern p of the island contains the most prominent recrea onal facilies. Hobie Beach faces south, and is a popular spot for windsurfing, small catamarans etc. On the north side of the causeway is the Rickenbacker Marina and Rusty Pelican Restaurant, in addi on to the island’s most architecturally significant structure, the Miami Marine Stadium. Completed in 1964, the sculptural concrete structure was designed by a team led by Cuban born architect Hilario Candela. Its lis ng on the World Monuments Fund 2010 watch list 7 environmental history As is typical of barrier islands, Virginia Key is a naturally dynamic en ty whose form and character fluctuates over me. Anthropogenic changes to the Biscayne Bay ecosystem have supplanted hurricanes and natural dal fluctuaons as the major cause of landscape change. Peter Harlem’s 1979 analysis of historical aerial photography provides a comprehensive review of changes to the structure of Biscayne Bay which parallel the urbaniza on of the region over the 20th century. The Miami mainland consists of a limestone ridge which separates the Everglades from the Bay and the Atlan c Ocean. Key Biscayne forms the southernmost part of a second limestone ridge underlying the chain of sandy barrier islands which protect the mainland coast (Harlem 16). Like other islands, Virginia Key was once covered predominantly with Mangrove which anchored sediment deposited by fluctua ng current and dal acvity (Harlem 26). In the 1930’s dredging and wall construc on began to alter current flow in the Bay. Sediment began to accrete to the north of the island providing area for expansion of the mangrove swamp. By the 1950’s the island had expanded to the north by almost a half mile. The eastern third of this new area was dredged to provide fill for the sewage treatment plant which was constructed throughout the mid 1950’s. The dredged area created a sink for sand eroding off Virginia Key Beach to the south. By the mid 1970’s je es had been constructed to slow erosion of Virginia Key beach. The northern p of the Key was surrounded by levees in the mid 1960’s and the area was used as a sanitary landfill (figures 4,5)(Harlem 94). The landfill area is now an EPA superfund site. The northwestern por on of the island was altered by the construc on of the Marine Stadium lagoon. The southern por on of the island was cleared for the Seaquarium, RSMAS campus, and federal facili es by the end of the 1950’s (figure 6). 5. Virginia Key Aerials, Harlem 4.

Note exis ng mangrove behind newly placed fill. rsmas campus development choice of site T he University of Miami marine laboratory was formally established in 1943, and its ini al home was in a private boathouse on Miami Beach. The research team grew, and through a series of contracts with state and commercial conserva on and marine resource interests, the ins tu on grew to the point where it needed a consolidated home. In 1951, Dade County offered the University a long-term lease on 6.38 acres along Bear Cut if a marine research building could be built within the year. Funds were raised with contribu ons from the fishing and boa ng community and through newspaper appeals. 2. Agassiz interior showing open plan and exposed structure andservices, Yehle the structure resembled the architecture of 1930’s Miami Beach. However, the structure was elevated a full story, acknowledging its exposed loca on. The Collier Building, a similar laboratory structure, was added two years later. Both were oriented east-west along the shoreline, maximizing southern exposure and onshore breezes for natural cooling poten al (figure 3). academic core Over the next decade, the three sec ons of Grosvenor were constructed, allowing for consolida on of the marine library, laboratories, and offices into 3. Collier and Agassiz from Bear Cut 1955, Yehle original structures Designed by Marion Manley, the Agassiz Building was opened in 1953 as the first structure of the Virginia Key Campus (figure 1,2). The elevated structure had no interior walls, and infrastructure was exposed allowing for adjustment according to varying research requirements (Yehle). Seawater was pumped in directly from the adjacent bay, crea ng a literal connec on between the scien fic life of the University and its physical context. A simple stuccoed concrete volume with jalousie windows and a con nuous horizontal shading fin, 11 one campus. A two level south wing was built first in 1957. A third level and a two level east wing were completed in 1957. In 1965 the three level North Grosvenor was completed (Yehle). The north wing was designed for an addi onal two levels. Built with a combina on of reinforced concrete and stuccoed concrete block, the south and east wings have ground levels at grade. Only the north wing is slightly elevated. The style of the three sec ons is fairly consistent with horizontal banding, horizontal windows, and simple overhanging concrete plates marking the entries (figure 5). In contrast to the Manley design, the Grovesnor buildings seem to take li le cue from their tropical waterfront loca on. South Grosvenor has some southfacing windows, but the other two structures face an internal courtyard used primarily for outdoor storage of research equipment. Double loaded corridors mean that workspaces have light only on one side, and li le cross-ven la on. Low floor-to-floor heights emphasized the horizontality of the structure, but limited space for horizontal distribu on of u li es and for convec ve cooling in a hot climate. Had they been built, the upper levels of North Grosvenor would have had be er poten al to gain views and breeze from the Bay. 6. Grosvenor East entry, Yehle 5. Rendering of Grosvenor South and East, Yehle The formal entrance of the complex is on the East side, and was originally visible from the Rickenbacker causeway (figures 6-8). Street frontage took precedence over connec on to the site. This core complex was completed with the construc on of Glassell in 1966. With an open ground level, two levels of labs, plus roo op salt-water se ling tanks, the bar building created a ver cal element perpendicular to the original low-slung waterfront labs (figure 9). The upper levels were marked by an extended concrete frame. The south elevaon facing the water had no windows, relying on an abstract pa ern of scored stucco to break down the scale. Period photographs show a parking lot covering most of the remaining available space. 4. Founder Walton Smith on tractor, Yehle 7. Campus entry c. 1960, Yehle ancillary buildings 12 Meanwhile, three small buildings were added in 1960, on an axis perpendicular to the bay. The three two story structures were an opera ons building, a small dormitory, subsequently converted to the tri um laboratory, and a refrigera on building (figures 11-14). These were u litarian concrete structures, narrow bar buildings, slight eleva on from exis ng grade and concrete overhangs being the only concessions to clima c condi ons. Oriented roughly north south, they were fully exposed to the western sun and minimally exposed to views and onshore breezes. They are also rotated about 20° to the 8.

Glassell from Bear Cut, author The next major structure came in 1971 with construc on of the Doherty Marine Sciences Center. Hugging the west edge of the site, the three level building rose up behind the opera ons building with an elevated entry courtyard and a series of exposed stairways. Deep overhangs, varied floor heights, and ver cal concrete brise-soleil place the building in the Brutalist school popular 10.

A double height lobby and generous waterfront terrace give the building a graciousness which contrasts with the Spartan character of earlier campus buildings. Elevated a full level, and consciously reaching toward the water despite its orienta on, the building is also the most specifically responsive to the site. A cafeteria and bar open to the waterfront deck, and as the only inten onally designed common spaces on campus, remain its social core (figure 16). The last major structure mirrored Doherty, framing the east edge of campus along the Rickenbacker Causeway. The Science Lab and Administra on Building (SLAB) building was completed in 1985 and now houses the library, administra on offices, dry lab and office space. Designed by New York architects Abramovits-Harris-Kingsland, the building was the result of a comprehensive 1979 master plan completed by the same firm. They also designed a north wing which was added to Doherty in 1980 to house CIMAS (Coopera ve Ins tute for Marine & Atmospheric Science). 16. Doherty, Commons space, Yehle 14 15.

In contrast to the durable concrete construc on of many other campus buildings, the Administra on building contains a large amount of steel structure with non-structural stucco cover panels.

Planning Context Miami-Dade Water & Sewer Federal Agencies Miami-Dade Schools University of Miami City or County Parks 1. Land ownership land ownership T he most immediately applicable planning documents are the campus master plans completed by the University of Miami. Before referencing those it is important to consider the context of Virginia Key as a whole, and its contribu on to the general urban context. The site is located in unincorporated Miami-Dade County, and is listed as unzoned. With excep on of the federally owned parcels across the causeway, all the land surrounding the campus, including the Seaquarium site is owned by the Miami-Dade Parks and Recrea on department. The causeway is owned by the County as well. The wastewater treatment plant is owned by Miami Dade Water and Sewer. However, the City of Miami owns all the coastal land north of the causeway including the former landfill to the north, Virginia Key Beach Park, and the Marine Stadium site (figure 1). county comprehensive plan All land in the county is covered by the Comprehensive development Master Plan (CDMP). Several elements of the plan have par cular relevance to Virginia Key. Perhaps the most impac ul is the introduc on to the Conserva on element of the plan which states “The environmental sensi vity of MiamiDade county is underscored by the fact that urban por on lies between two na onal parks Everglades and Biscayne” (Miami-Dade, CDMP IV-1). This secon also emphasizes the economic importance of environmental protec on in light of the County’s reliance on tourism. The Coastal Management Element emphasizes restora on of coastal habitat, especially in areas which are potenal habitat corridors. Increasing public waterfront access is also men oned (VI-9). The designated land uses for 2015 to 2025 are indicated in figure 2. The RSMAS site is designated for ins tu onal use, but most of the island is designated for parks and recrea on or environmentally protected park. 19 2. 2015 Land Use Plan, Miami-Dade County city of miami virginia key plan While the County does not have a specific area plan for the Key, the City of Miami recently completed a Virginia Key Master Plan. While uses of the island have been historically mixed, the 2009 plan, wri en for the City by EDSA, focuses exclusively on enhancing sports and recrea onal facili es. The plan seems misguided from the outset. While the City controls only a por on of the island, a coordinated plan should have been prepared with coopera on between City, County, and major ins tu onal stakeholders. Successful planning for an 860 acre island cannot be conducted piecemeal. The centerpiece of the plan is an ac ve playfields complex containg six soccer fields, eight baseball diamonds, and a football field, along with running track and tennis facili es (figure 3). 20 3. Virginia Key Master Plan, EDSA for City of Miami This kind of program seems ill conceived for several reasons: • Loca on Crea ng a large campus for ac ve sports far from any popula on center is not compa ble with the kind of mixed-use integrated development called for in all the City’s planning documents. Coastal park facili es should priori ze water dependent recrea on. • Environment Conver ng one of the region’s largest tracts of coastal forest into a series of maintained sports fields is the environmental equivalent of urbanizing this area whether or not the grass is green. The plan goes on to state that 77% of the land in the planning zone is “unuseable” (EDSA 6). By this they mean not available for ac ve public recrea onal uses. This narrow defini on of benefit reflects the self-iden ty of Miami as a tourist oriented pleasure metropolis. Diversifying this self-concep on strikes at the essence of increasing the resilience of the community as a whole. university of miami master planning While the mission of the ins tu on may be more far reaching, master plans prepared for RSMAS have focused on space alloca on and distribu on within the exis ng campus framework. S ll, the 1979 plan by Abramovits illustrates sound goals for campus enhancement which have yet to be realized. The following guiding principles are outlined (Abramovits 11): 1. More efficient land use. 2. Non-interrup on of ongoing research work. 3. Crea on of a collegial environment. 4. Separa on of pedestrians and vehicles. 5. Compactness and fullest u liza on of working space. 6. Simplified administra on of research. 7. Reorganiza on, upda ng, and be er u liza on of energy distribu on and u lity systems. 8. Be er Resolu on of the parking problem. 9. Provision for limited recrea onal space and explicit defini on of outdoor space. 10. An architectural statement of significance on Virginia Key. 1979 plan At the heart of this plan was the intensificaƟon of structure at the perimeter of the site which would allow the center to be gradually unbuilt, leaving a classic academic quadrangle with open water as the fourth wall (figures 4,5). While the Administra on Building was realized largely according to the 1979 plan, the University is just preparing to break ground on the second major structure proposed by the plan.

A er a programming study, Cambridge Seven proposed a new structure along the north edge of campus which essen ally followed the 1979 plan. The major varia on from the 1979 proposal was that a second east-west bar should be constructed, crea ng two major courtyards, the northerly one fully enclosed, and a smaller southern space open to the bay. This would allow for added and updated indoor space, but lost something of the simplicity and impact of the 1979 diagram (figure 5). 2010 seawater lab proposal The Univesity expects to break ground this spring on an updated version of the sea-water lab building proposed in 2005. The 2010 version has a simplified footprint, but much finer grained eleva ons than previous campus buildings. Parking is proposed for the ground level, with two levels of office and laboratory space above. The building is organized along a central east-west corridor, with a double height common space at the east end facing the Rickenbacker Causeway. lost opportunity for tropicalism? The building is designed to allow for expansion on the north side. Unfortunately, this means that workspace facing the poten al expansion will have no natural light. The central corridor, glazed facade, and minimal covered exterior space suggest a a design approach which relies heavily on mechanized thermal control and ligh ng.

The Miami master plan for Virginia Key focuses primarily on redeveloping the parks to increase their recrea onal poten al. However, the opportunity to develop a more integrated community of top-level marine research and educa on facili es holds poten al for crea on of an economic development node which could help diversify Miami’s service oriented economy. A similar node for medical and biotech research is being developed with involvement by the University in the area of Jackson Memorial Hospital. tropical research hub as economic development opportunity Miami is the major metropolis of the Caribbean, and as such is a center for tourism, but also for banking, trade, health care, higher educa on and research. The adjacency of RSMAS to federal tropical research facili es, and the poten al for Seaquarium and MAST Academy to deepen the rigor of their missions, gives Virginia Key unique poten al to emerge as regional center for tropical coastal science. In addi on, the natural resources of the key, and the urban infrastructural challenges of the wastewater treatment plant and former landfill provide an ideal laboratory for research on resilient and restora ve coastal development. This cluster of academic and federal research facili es exists in only four other places in the United States: La Jolla/San Diego, Monterrey, Sea le and Woodshole Massachuse s. In all of these loca ons, the concentra on of marine research ac vity has drawn other related academic and economic interests, and has a significantly benefi ed the local economy through the crea on of highwage technical jobs, and increased a rac veness to educated entrepreneurial residents. These places are models of economist Richard Florida’s asser on that the most dynamic economic growth will occur in areas which combine natural beauty, dynamic urban culture, and high level economic opportunity (Florida reference) 24 While this project does not a empt to develop a revised master plan for Virginia Key, or the RSMAS campus, the principles which guide it will be an integra on of the values expressed in the various exis ng plans. Not intended as a comprehensive list, the following are some important principles which will guide the design. as per rsmas planning documents • Create a more unified and hierarchical campus experience. • Expand and organize facili es for research (both indoor and site based). as per miami-dade county comprehensive planning • Respect and enhance ecological func on as per Miami-Dade County comprehensive planning. as per cty of miami virginia key master plan • Enhance public access to waterfront. • Create opportuni es for non-motorized circula on throughout the Key. addiƟonal principles • Enhance visual and func onal connec on between campus and surrounding urban and natural resources. • Enhance poten al for programma c interac on between exis ng ins tu onal uses. • Encourage development of the en re key as a laboratory for urban ecological research. 6. P erhaps because of the newness of the school, and the newness of its city, the Campus of the University of Miami began as a laboratory for forward thinking ins tu onal planning and architecture. Post-war Miami enjoyed a luxury of space and cultural youth which allowed for the development of the sprawling modernist Main Campus. The campus has become a verdant counterpoint to the densifying city around it. While similar architecture has been employed for the Rosens el School of Marine and Atmospheric Sciences, the physical context is quite different. Situated on approximately six and a half acres at the southwest corner of Virginia Key, the school overlooks Bear Cut and the mangrove fringe of Key Biscayne. Site Analysis Summary Currently, several smaller buildings block visual, and to a certain extent physical access to campus waterfront. Access to views, and connec on to water for func onal research purposes will be an important design considera on. Ecological considera on of the land/water interface will provide an addi onal criterion by which to evaluate si ng considera ons. relaƟonship to virginia key Finally, the Rosens el School should take be er advantage of its loca on. A rela vely undeveloped tropical island is a rare and valuable thing, even more so at the center of a major metropolis. The interiority of the campus and buildings within should be reversed, and RSMAS should seek a way forward which engages its surrounding community and ecology. Occupying filled land at the edge of the bay, the Rosens el site epitomizes Miami’s juxtaposi on of fragile marine ecosystems with urban development. Within the campus, the concrete buildings which provide a backdrop for green on the Main Campus are almost en rely surrounded by parking and roadway. Casual building placement fails to create posive outdoor spaces on the small site. Despite its spectacular se ng, the physical campus is an underwhelming home for a globally renowned center of the marine environment. increase richness and intensity It seems that there is poten al to create a much more vibrant human center, while also enhancing the campus open space and its rela on to surrounding natural context. If the UM Main campus can be seen as a park, an area of vegeta on, openness, and relief from the city, I can envision the RSMAS campus as the opposite – a dense, rich cluster of complex human ac vity, set against parks and open space (figure 1). um main campus The exis ng campus was developed in a somewhat ad-hoc manner, where buildings were added over me based on available space, but without any overriding spa al organiza on. The two largest buildings line the east and west edges of the site, and are of more recent construc on, presumably func onally viable for the medium term. A new wet lab has been proposed and designed to line the north edge of the site. The remaining structures are sca ered throughout the middle of the site, and are all considered func onally obsolete. Even the most rudimentary master planning suggests that the core of the site could be opened up to create more clearly defined campus space. Placement of proposed buildings would have to reflect a compromise between ideal future loca on and phased replacement of space in exis ng buildings. rsmas 25 1. figure/ground - urban/green site diagrams relaƟon to causeway 26 2. current site aerial, google primary axis paved and open space 7. A Program Framework n essen al characteris c of good architecture is the integra on of mul ple disparate program requirements into a unified composi on. I will use the several meanings of resilience as a means of organizing the programming phase of this project. As defined at the beginning of this document, resilience – is the capacity of a given ecosystem to maintain its essenƟal characterisƟcs despite stressors including changing environmental condiƟons. The Rosens el campus offers an opportunity to test the poten al for thoughtful, humane, and ecologically sensi ve coastal urban redevelopment. As with any ins tu onal client, various interests must be balanced in order to create a campus which op mizes benefit to the larger community while serving the specific programma c needs of its members. In this instance, there are three primary client interests: Addressing the defini on given above, there are three components. First I will work with RSMAS to create a working list of “essen al characteris cs” which define two ecosystems; one, the Virginia Key/Bear Cut coastal margin, and two, the University community which I view as part of the Virginia Key system. Second, I will outline expected system-level stressors. Third, I will iden fy those which may be mi gated through architecture. • The University of Miami as a whole • Specific interests of the Rosens el School of Marine and Atmospheric Sciences • The Virginia Key ecosystem program criteria A truly resilient campus will sa sfy a broad range of program needs. In the largest sense, the goal is to create a place which supports a thriving intellectual community in a manner which is integrated into its urban and ecological context. Improvements to the RSMAS campus should be evaluated in the context of campus planning needs, but also for how they contribute to the enrichment of the larger Viginia Key/Bear Cut ecosystem. Campus planning for RSMAS should consider basic issues such as parking and transporta on in conjuncon with adjacent facili es, development of pedestrian and bicycle networks, public waterfront access, visibility of RSMAS campus func ons to the public, and program diversifica on including addi on of housing and compelling community spaces. Beyond this, campus improvements should be designed to enhance the interface with Bear Cut. Improvements should go beyond a generalized low-impact building approach, and target enhancement of specific ecological func ons. For example, green roofs could be designed to provide habitat for shorebird species which would have found refuge in the na ve coastal scrub forest. Buildings could be connected by elevated walkways which would allow for restora on of seasonal flooding on parts of the campus and replan ng of func onal pockets of mangrove. By iden fying quan fiable ecological goals, input from disciplines such as restora on ecology is given greater weight in the design process. client Because of their centralized structure, informed decision making process, long planning horizons, and respect for innova on, universi es can play a unique role in se ng the tone for future development of surrounding communi es. A successful program will have to balance the some mes conflic ng needs of the three communi es above. A successful design will both reinforce the essen al characteris cs of the three, as well as improve their resilience to future stress. Preliminary ques ons are as follows: university prioriƟes • How can RSMAS be be er integrated into the academic and social life of students on Main Campus? • How can RSMAS campus facili es be improved to provide opportunies for students from a variety of disciplines to study coastal issues in an integrated manner? • Could an improved RwSMAS campus serve as a recrui ng tool for the larger University? • Can the RSMAS campus reflect the President’s desire to incorporate housing into new University structures? rsmas prioriƟes • How can new construc on improve spa al defini on of the campus, helping describe a hierarchical sequence of posi ve open spaces? • How can infrastructure, u li es and circula on be streamlined? • What kinds of spaces are needed to improve the func on of the research community? • How can obsolete structures best be replaced? • What combina ons of program would be most easily financed? • What kinds of non-academic program would improve campus life (ie. housing, community space?) • If housing were to be added, what type and how many units would create a cri cal mass of residents? • How can physical improvements impact the durability of RSMAS as a human community focused on top-level marine ecological research and conserva on? 27 virginia key ecosystem urban • How can be er physical connec ons be made to adjacent ins tuons? • How can the RSMAS campus be opened up and integrated into the system of public waterfront trails which runs from Brickell, out the Rickenbacker Causeway, and onto Crandon Park? • How could campus edges be redeveloped to func on as es, rather than barriers to adjacent uses? ecological • What func ons of the system have been most compromised by coastal development? • What off-site impacts does the campus have? • What adverse impacts could be mi gated through architectural or site improvements? • What campus improvements could contribute to increased func on or resilience of the ecosystem? building resilience sea-level Rise The concept of resilience has several implica ons in terms of evalua ng the architecture itself. Most obvious is physical resilience to climate events including hurricanes and sea-level rise. Examples from other low-lying geographies are informa ve, but South Florida presents an unusual set of condi ons. Dutch architecture represents a cultural bias toward long planning horizons and durable, well detailed architecture. These quali es are appropriate to planning for university structures which are expected to accommodate sophis cated program requirements and endure over me. However, hurricane winds, intense sun, and humidity add addi onal stresses not considered in Dutch architecture. Coastal developments in Southeast Asia do face similar climate condi ons, yet few examples are expected to meet the high performance standards of University-level research facili es. thermal comfort 28 Ability to provide climate comfort through passive or renewable means is another aspect of resilience. Again, Southeast Asia provides some precedents. Integra ng tradi onal strategies into a high-performance building will be part of the challenge. Ideally, a combina on of passive thermal comfort strategies, efficient building envelope, minimizing ar ficial ligh ng demand, and though ul design of specialized laboratory equipment could result in a high performance research building which could operate with less dependence on outside power. While this seems unusual for a university building, there are many examples of field research facili es which allow for high quality scienfic inves ga on in a much less resource dependent manner. Field sta ons should also provide good precedent for the integra on of housing into scienfic research facili es. While the actual number of units may be small in terms of the overall university popula on, I would hope to determine how many residents would be required to support the culture of integrated life and learning which is evident at facili es such as Duke Marine labs which incorporate some housing. program adaptability Another aspect of resilience, is the ability of a system to adjust to change while s ll maintaining its overall form. For architecture this implies a building which meets its current program, but is designed in such a manner as to accommodate future needs which may be quite different. Generally, this implies a modular system where structure and internal par ons are separate, as well as design of mechanical systems which can be easily accessed and adapted. The thesis will have to explore what this means in response to the par cular program. habitat In responding to the third client, the Virginia Key ecosystem, another set of metrics apply. From an ecosystem standpoint, resilience is o en a result of diversity of species and habitat structure. A building will impact these in two ways. First, off-site impacts need to be considered in terms of drainage, air pollu on, shadow cas ng, light pollu on etc. This kind of impact is fairly well described by the USGBC LEED ra ng system. In a coastal marine loca on adjacent to fragile habitat, a range of impacts must be considered including site disturbance during construc on, release of pollutants during maturing of building structure, and impact of maintenance prac ces such as pain ng or window cleaning. Second, and less explored is how the building can in fact replace or augment physical habitat structure which has been lost. One area I am curious about is the poten al for vegetated roofs to be designed to meet the habitat needs of specific species. An unintended but well documented example is the colonizaon of parapets and cornice structures by Peregrine Falcons in New York City. In the context of sea-level rise and climate change, roofscapes may be able to provide refuge for species such as shorebirds who may lose their natural habitat due to flooding, even if only during temporary storm events. cultural context Finally, architecture is a cultural product. A building is an expensive and impac ul statement about the aesthe cs and cultural values of its architects and client. While it will inevitably express the dominant values and aesthe cs of its moment of incep on, a resilient building will have aesthe c and cultural meaning whose value and legibility endure over me. Despite the newness of Miami as an urban center, there is a rich architectural vocabulary to draw from. While there is no history of se lement in Virginia Key prior to the 1940’s, the early se lers of the region followed the light wooden vernacular common to the American South. At present, there is a large collec on of mid-century concrete structures which represent the playful experimenta on with reinforced concrete construc on. Best known is the Marine Stadium, but are many other structures including park facili es and the concrete-screened NOAA facility which represent this period of Miami’s history (figures 1-3). The heavy brise soleil of the campus commons building place it in the company of other brutalist buildings of the period which con nue to explore the plas c quali es of concrete and the drama c shadowing possible with intense tropical light (figure 4). The more recent Administra on Building con nues to explore the vocabulary of Tropicalist ins tu onal architecture with its massive overhanging roof (figure 5). Any new architecture on the campus must be designed with these tradi ons in mind. 2. materials, aesthe cs of exis ng campus 29 proposed redevelopment sequence The redevelopment sequence illustrated below reflects current University redevelopment plans. The seawater lab is scheduled to begin construc on in 2011, with demoli on of Collier and Glassell to follow.

A 1. High Line Park. author photo Case Studies resilient ecosystem needs to have stable popula ons of the core group of species and stable func on in terms of ability to propagate itself. For this to happen, it must have a stable physical structure. This is the defini on of habitat: a physical structure which allows for the successful propaga on of a community. In developing the idea of a resilient campus suppor ng con nuing high-level study of the marine environment, a program can be defined which enumerates the variety and propor on of various func ons. However, in the same way that neither a plant nursery nor a pet shop is an ecosystem, a collec on of specified spaces does not inherently make an academic community. The ques on becomes, what cons tutes resilient habitat for the RSMAS community? The following paragraphs examine the dialec c between formalism and func onalism as generators of architectural and urban pa ern. Rather than viewing them as mutually exclusive approaches, I would argue that they are inherently complementary. The two pairs of text above illustrate two separate but overlapping debates on the nature of contemporary architecture and urban design. At the urban design scale, Landscape Urbanism is challenging the formalist basis of New Urbanism in favor of a fluid reading of urban space which emphasizes interconnec vity of infrastructure and ecological systems overlaid with site specific narra ve reference. The first reference is an excerpt from Charles Waldheim’s introduc on the Landscape Urbanism Reader, a collec on of essays which suggest a framework for meaningful urbanism in the post-industrial city. The emphasis is on reappropria on of the horizontal plane, replacing the insustrialized asphalted ground plane with contemporary gardens which provide ecological func on in addi on to providing space for social interac on. Andres Duany has explicitly cri cized this movement for its inability to address quesons of architectural density, spa al hierarchy, and func onal efficiency which cons tute important elements of New Urbanist theory. That he sees it as a threat to the supremacy of New Urbanism is an indica on of the resonance of the Landscape Urbanist approach in contemporary culture, as well as the connuing percep on that urban design theories are mutually exclusive. I would argue that both theories provide valuable tools for analyzing and designing the contemporary city, and are in fact quite complementary. high line park An example of the successful integra on of ideals from both camps can be found in the redevelopment of New York’s High Line. A mile long ribbon of green floa ng over Manha an’s Lower West Side, the High Line opened to the public in June 2009. The High Line is the glamorous cousin of the “rails to trails” projects which have gradually been transforming disused rail corridors into linear public open spaces. Combining an innova ve design, high quality materials, and me culous quality of construc on, the ini al sec on of the High Line Park has become a showpiece of contemporary urban public space. However, underneath the showy visuals lies a though ul strategy for the transi on of an underu lized industrial quarter into a vibrant mixed-use urban neighborhood with the park at its heart. While the spectacular Manha an loca on is unique, the project represents a scalable and replicable approach for catalyzing redevelopment of centrally located industrial districts. Running from West 34th Street south to Gansevoort Street, a block east of the Hudson River, the High Line was constructed in 1934. The 1.5 mile rail line was elevated 30 feet to separate industrial rail ac vity from surface streets. The line was placed mid-block north to south in order to avoid the blight associated with elevated subways (Friends of the High Line, 2010). The railroads owned an elevated easement, but the land underneath and air rights con nued to be a ached to adjacent lots. This created a unique urban pa ern which has impacted contemporary op ons for redevelopment. By the 1980’s the line was unused and owners of adjacent proper es formed Chelsea Property Owners, Inc. promo ng demoli on in order to facilitate redevelopment of their land. However, rail preserva on advocates fought the demoli on, and in 1999 neighborhood residents Joshua David and Robert Hammond founded the non-profit Friends of the High Line, seeking redevelopment of the structure as a unique public open space. Despite the concern of adjacent owners, poli cal support for a public adap ve re-use and the lack of open space in that por on of the city led to a commitment from the City and the State to preserve the line. (Design Trust, 7) 35 2. High Line route. adapted from google Designed by James Corner Field Opera ons and Diller Scofidio + Renfro, the park combines sleek pavement and furnishings with wispy eclec c plan ngs meant to evoke the weeds which were colonizing the abandoned elevated rail line. The lightness of form and material emphasizes the solidity of the original suppor ng structure giving “weight” to historical memory (figures 1,3). The park spaces are loosely programmed but mul -func onal, providing an aesthe cally appealing pedestrian route as well as space for lounging, viewing the city and river, and taking in informal music and art events. Ecologically, the park serves as both patch and corridor, a linear habitat element for birds and insects created by an isolated island of vegeta on. The non-hierarchical nature of the design allows for unlimited future expansion, implicitly valuing flexibility and connec vity over autonomy of the ar s c endeavor. 3. High Line Park. author photo on together, suppor ng Landscape Urbanist ideals of socially, ecologically, and historically referen al landscape in the context of the dense mul -use urban structure advocated by the New Urbanists. In the example of High Line Park the open space repurposes what was an anomalous open patch within non-hierarchichal grid matrix. By crea ng a moment of importance in that patch, the grid is given hierarchy through a gradient of proximity to the new space. It is the interplay of infrastructure, site specific open space, and built urban fabric which gives meaning for Landscape Urbanist and New Urbanist readings. Despite safety concerns about urban open spaces segregated from the street, the park has been immensely popular from the start. Combining cri cal and popular favor, the park has become an instant “monument,” a spa ally explicit icon which serves as an urban reference point. This is the key point of convergence with New Urbanist ideas. As a monument the park becomes a catalyst around which new or repurposed urban fabric can be structured. 36 A West Chelsea Special Zoning District was created, and specific formal guidelines were wri en to guide the development of adjacent structures. An es mated $2 billion has been invested in the neighborhood as a result of development of the park (HR&A), sugges ng that the park has had significant impact on the surrounding architectural fabric. The zoning guidelines emphasize a mix of uses with retail and gallery space at the ground level of office and residen al towers, and aim to protect the diversity of use in the neighborhood while assuring consistency of form (NYC Zoning Code Ar cle IX, Ch. 8 98-00 to 98-25). In this way it seems that the park and surrounding urban district func4.

An interes ng example of the peripheral condi on can be seen in Jean Nouvel’s Red Wall project in Bergamo Italy. Located along the A3, an eight-lane limited access highway, the site consisted originally of an exposed grouping of low-rise research buildings. Nouvel’s scheme lines the A3 with a kilometer long red wall roughly five meters high. The wall creates structure at the scale of infrastructure, a landscape piece which stands up to the highway and creates protec ve shelter from it. New research buildings are aligned perpendicular to the wall to create a series of comfortably scaled open spaces. The central open spaces are more park-like with lawn and sca ered canopy trees, while the landscapes into which the wall terminates have been developed as constructed marshes. 1 exis ng urbaniza on 2 autostrada introduced 3 freestanding commercial space linked to highway 4 red wall added blocking wind and noise, crea ng south facing space 5. project views, Lotus The wall, a landscape interven on of post-industrial scale and character thus mediates the effect of the highway and creates a zone for habitable gardens and more delicate architecture behind.

Venice Hospital model, from Allard venice hospital Landscape Urbanism is only the most recent manifesta on of a con nuing search for a design framework which can accommodate the fluid and complex nature of the modern city and its vast horizontal spread. The second pair of quotes above references differing approaches to this ques on at a more architectural scale. The first is from Guillermo Jullian, a protégé of Le Corbusier and his collaborator on the 1964 proposal for a hospital in Venice. Having just returned from a Team 10 conference, Jullian became interested in models of organic growth as form-givers for architecture (Allard 20). “Then to create places Coralize” suggests an interest in the repeatable and scalable forms we now call fractals. The plan for the hospital consisted of horizontally layered programma c strata organized around a series of repeatable courtyards. Extending from medieval Vene an fabric out over the water, the design recalled the texture of the old city while proposing a formal system which could adapt to the complex and dynamic demands of a large modern ins tu on. Like a coral, the overall structure was generalized and non-hierarchical while the specific elements – pa ent rooms, opera ng theaters etc. -- were carefully detailed to serve their specific func ons. The low, inward-looking hospital complex would appear to grow naturally from the exis ng city, eschewing the heroic modernism generally associated with Le Corbusier. Jullien made the analagy to coral in reference to a larger discussion about organically formed architecture, but it is par cularly apt for the Venice hospital. As the hospital is built largely over water, the buildings are free to take the form which emerges naturally from func onal and programma c requirements. Rather than exis ng within, the buildings create their own urban structure. The biological analagy is also evident in the ver cal layering of the plan. The first level contains primarilly outpa ent func ons, while the top level is designed for flexible placement of inpa ent wards (figure 8). Sandwiched between is a mezzanine devoted to circula on and service, a kind of vascular system for the hospital. 38 In a way, this approach has es to the current interest in parametric design. Yet, there is also a strong sense of his rical reference, as if a piece of the gene c code of old Venice has be implanted into the work. The scale and rythm of the courtyards echoes the adjacent fabric, while the organic adaptabli y of the plan carries with it some of the spontaneous quality of an evolved place. 9.. upper level and mezzanine plans, Le Corbusier from Allard salk institute Almost exactly contemporary to the Venice hospital proposal, is Louis Kahn’s iconic Salk Ins tute. Completed in 1966, the project is an altar to the scien st-hero cult of a confident post-war America. Where the Venice hospital references the common matrix of the city, the Salk ins tute alludes to the temple-framed central spaces of ancient Greek ci es like Ephesus, simultaneously celebra ng civic achievement, and humbling it in rela on to the vast ocean beyond. Like Le Corbusier, Kahn is also intent on enhancing the space of the individual within the complex. The serrated facades give expression to the spaces of individual study which form the heart of the program. Yet the individual units are clearly subordinate to the powerful axial central plaza, and the dialog established between civilized humanity and mys cal ocean. Salk’s desire for a place “Picasso could come to visit” is sa sfied by Kahn’s presenta on of a “complete” work of art. Like Le Corbusier, Kahn uses sec onal layering to separate infrastructural space from primary spaces. Mezzanine mechanical spaces are sandwiched between primary levels containing open labs and individual studies. Within each floor, spaces are le open to allow for maximum flexibility (figure 9). Flexibility is given at the scale of large indiviual rooms which are contained within a strictly defined plan diagram. This differs from the Venice hospital plan where individual workspaces are more proscribed, but the overall structure is adaptable. The contrast between the “Mat Building” approach to Venice hospital and the formal symmetrical hierarchy of the Salk ins tute provides an interes ng parallel to the current debate between organically inspired Landscape Urbanism, and the formalist basis of New Urbanism. Mat buildings are flexible, adaptable, democra c. They could also seem labyrinthine, herme c, and pedestrian. The Classical formalism of the Salk Ins tute is legible, engaging, and inspiring, but also rigid and difficult to adapt. Its reliance on formal harmony subjugates the individual user and his or her changing requirements. 10. Salk Ins tute courtyard, Steele 11.. Salk Ins tute typical lab wing sec on and plan, Steele applicability to RSMAS The four case studies referenced above all seek to balance funconal structure and narra ve reference to create meaningful urban districts. A resilient campus community will have to address the changing func onal requirements of a complex ins tu on. However, it will also have to have a legible structure which gives form to the dreams and desires of the community. As Central Park or the High Line give meaning to the Manha an grid, or Saarinen’s hall gives meaning to flight at JFK Airport, func onal matrices can be inflected by spaces which give meaning to the whole. 39 40 Works Cited Abramovitz-Harris-Kingsland.

ConservaƟon biologists have been interested in the idea of resilience – that is the capacity of a given ecosystem to maintain its essenƟal characterisƟcs despite stressors including changing environmental condiƟons. Stressors can be events of short duraƟon and high intensity such as fire or hurricane, or long term events such as the aging of a mature forest canopy. The concept of resilience has also been applied to human communiƟes, and implies durability of a range of elements from economic and social stability to ability of infrastructure to withstand the pressures of climate change. This thesis suggests that human communiƟes are inseparable from the natural communiƟes in which they are set. Responsible development should consider the resilience of both. The goal is to develop architectural and open space improvements which would help create a vibrant academic cluster in which to house a greater range of teaching, research, living, and recreaƟonal acƟviƟes than are served by the exisƟng campus. This expansion of architecture and infrastructure would be carried out in a way which reduces the site’s vulnerability to storm events and climate change while enhancing ecological funcƟon and the site’s interacƟon with adjacent natural areas. f1 ecological campus challenges/ proposed solutions Virginia key was originally a valuable produc ve mangrove at the head of Biscayne Bay. The en re key is now filled. The area in proximity to the University’s marine campus as well as the Seaquarium is currently en rely paved for parking. All ecological value is lost. In addi on, the paved areas contribute to the heat island effect. The lack of vegeta on and topographic diversity make the developed structures extremely vulnerable to storm events. Given sea level rise and increasing ocean temperatures the frequency of storm events are predicted to increase.

Faculty and students work on a range of marine and climate topics, but the school lacks a coherent sense of mission with regards to sustainability – humanis c values, connec on and purpose for local region. Lack of communica on between researchers diminishes potenal for learning synergies. A resilient ins tu on will have diversity of output within a clear values framework as well as strong communica on between members. Strong academic ins tu ons usually engage with their communies/regions which provide students, staff, and a learning environment –they need to act as engaged corporate ci zens. Solu on: • Create more open lab and learning space. • Reverse par of major buildings so that circula on is on exterior and facing on to posi ve open spaces. • Add housing to allow for core resident community, visi ng scholars, and more informal campus life which can strengthen community sensibility. • Facilitate the connec on between campus and its neighbors through improved physical connec ons, provision of common space for shared mee ngs and conferences, enhance connec ons to natural physical context. design inspiration • Ruins and tents: meless structures with adaptable skin • Structure of buildings inspired by marine forms (e.g. coral forms, whale and skeletons) program As has been outlined earlier, this project will use rela vely expansive defini on of program. Specific site and building interven ons will be designed with an eye to the immediate func onal needs of the School, but also with reference to the idea of resilient community. The proposal will include a combina on of structure, site and landscape interven ons which will support the school in its growth, as well as suppor ng the Virginia Key community and ecology.
