TRANSITIONAL GATEWAY University of Nevada, Las Vegas • Las Vegas, NV, U.S.A.

As the city of las vegas continues to grow, all parts of the city that were once just interesting additions to the metropolitan equation become more important. One portion that fits this characteristic is none other than the university of nevada, las vegas or unlv. This university continues to grow and serves as the leading system of higher education for southern nevada, but also with a growing institution comes a developing identity and consequently, this identity may need to be addressed in the situation of unlv. The thomas & mack center, at the moment, serves as a large portion of unlv’s identity due to the facility’s large amount of events that are held each year. Generating millions of tax dollars and attracting millions of people annualy, this area of campus has the ability to serve as the starting point to attracting visitor to other areas of unlv’s main campus. Lying directly behind the t&m center and cox pavilion facilities, is a drop off area to the

c

portion of campus that sees a large amount of use by students daily. Zoning in on the back doors to the event arenas, the pedestrian tunnel underlying the arenas, the student drop-off zone, and a unique stretch of pathway that connects unlv’s gym road, a major campus artery, to the event arenas, respectively, a series of possibilities open up regarding 2 key factors and 3 usability factors that give Character to this area. The key factors to take into consideration are safety and identity for thie entire site. The 3 usability factors that determine the site’s overall ability to create a proper connection and Transitionary bridge are circulation, erosion, and vegetation, which all pair with future design decisions regarding the use of institutional space and quality.

Located in the heart of las vegas, nevada, within the university of nevada, las vegas, the site sits in a very crucial point between a large event Space and large amounts of class and maintainance space. The entire elevation of the site ranges from 2,027 feet to 2,062 feet since a majority Of the site’s space is situated on a hill overlooking the east-end of the campus. Encompassing a total area of about 86,000 square feet, there is a large amount of space that has potential for reconfiguration and utilization. As with the rest of the city of las vegas, the climate of the site is Subtropical/hot desert (bwh) based on the koppen climate classification system. Being semi-arid, many considerations such as only receiving Only 4 inches of rain annualy and lower than 10% humidity are to be taken into consideration. Desert characteristics such as the ones Previously mentioned, are what play a major role in the three key issues of bridging the transition.

The Student Services Complex assists in many activities such as: Enrolling students, paying tuition, & registration.

Utilities such as a large A/C unit, two large power box transformers, janitorial storage areas, & shut-off valves can be found here. The area is small but plays an important role in the functionality of nearby buildings and outdoor electrical fixtures.

TRANSITIONAL GATEWAY Programming

48.5 Million Visitors

For many, the journey into las vegas begins at the McCarran International Airport, located directly southwest across the intersection of Tropicana & Paradise. Since the airport is so close to campus, it might be thought that the main core of UNLV would have more out of state visitors & students. As a matter of fact, the airport saw 48.5 Million visitors in 2017 alone. Beginning at the airport, signs can be placed just outside of the terminals & parking garages advertising the programs & curriculum here at UNLV. Visitors to the campus would then generally park in one of The Thomas & Mack parking areas. From there, visitors can be guided by signage, which may be utilized more often to create a gateway towards the academic core.

Seperating Traffic Types

Pedestrian foot traffic has almost always been and is currently Constricted, forcing together foot and vehicular traffic, in the area that Exists between the cbc and the ssc, making the overall strategic value low In accompanying vast amounts of people like gym road; perpendicular and to The east of the site. In the upper drop-off zone, a large area of concrete Serves little purpose to accomidate an area that only needs a sidewalk-sized Parthway, while the lower drop-off zone appropriately targets handicapped Individuals, pedestrians riding the rtc bus route, vendors, students, and Even visitors to the thomas & mack center’s sporting events.

Diverting Soil Runoff

Quite possibly the most noticable issue of the site, intertwining with Safety - the poor and dry soil conditions are assumably being caused in part by poor irrigation and storm water management practices. On an average semester day, one can observe cracked, hard, & loose top-soil, being stemmed from faculty-used golf carts & their tire tracks. As noted to the left of the current and curved pathway, Erosion in the area is caused by poor circulation issues. Other interesting notes of erosion are occuring on the south half of the site by excessive pooling of water combined with near-impermeable surface soils.

Using Less Water

While there is a decent amount of vegetation currently present At the site between unlv’s cbc and student services complex, the type of vegetation and quality of this vegetation is Argueably fair to poor. Existing california-fan palm and Mexican-fan palm hybrid trees dot the northern portion of the Site, using large amounts of water to stay quite healthy, while On the southern half of the site, mostly native shrubbery takes Up only small amounts of water but continues to serve only as a weak buffer against pedestrian traffic.

Concepts

Circulation.

Convert current pathway to a zig-zag pattern to serve multiple purposes: 1) Slow down all types of traffic. 2) Allow for pedestrian access only - eliminating possible golf cart accidents. 3) Create a memorable gateway entrance experience for all pedestrians.

Erosion.

To address the surface runoff conditions, a desert-style swale can be placed through the most troublesome areas of the site.

Vegetation.

Adding multiple-terraced sections with drought-tolerant plant material allows for a visual buffer between the Sports/Events arenas and the Primary Education core of the University.

SPACE HABITATION

Parametric Modeling in boardwalk design • Torrey Pines City Beach, CA, U.S.A. What defines a space? Sometimes we go about our daily lives without ever thinking twice about the environment that we are in and how it was intended to be experienced. There are countless, subtle characteristics that are involved in the formation of each and every space that we interact with. The possibilities are endless when thinking about the number of variations, abstract languages, and combinations of human interactions that will take place in any given space. Pushing the envelope and blurring the lines between what makes a space definite or indefinite gives a whole new meaning to the culture of the built environment. Taking this set of charateristics and combining them with natural occurances is what begins to create a new habitat. Whether it be

through nature or through the mind of a designer, the intent of your experiences in a place can either be specifically defined or abstract. Whether it be the material in relation to the weather or the inconspicuous hues carefully layered into the stone pavers, our habitation and occupancy of a space has a certain standard of living intent. The coastal location of Torrey Pines City Beach, in California, explores the elements brought on by a high usage of space, a strong and lengthy amount of annual sunlight exposure, and a chaparral climate. Assessing the large variations in color and completely unique forms, while conscious of diversity in activities, can prove to be a challenging task in the execution of tailored pathways in a coastal setting.

ABSTRACT LANDFORMS

Unique creation & texture in the showcasing of site analysis • Advanced Digital Media Storytelling through landscape can be done solely through the manipulation of the information that is given. Numerical values placed on an axis can begin as one simple set of negative or positive points in the X, Y, or Z directions. A typical approach on how this data is interpreted would have a given two dimensional graph structure with points in space respective to their location in their distance from the coordinate 0,0. Obviously, this system is familiar in visual patterns that we come across frequently.

When interpreted into a graph, these visual patterns can take on new characteristics, unseen in their previous renditions. This is when complex algorithms can be interpreted and manipulated to show data in different ways. An image, for example, is composed of large amounts of data. Darker shades

13

and lighter shades can all be interpreted as values that can be transformed into visual constructs - thus illustrating characteristics taken from a real world analogy. In this sense, landforms can be analyzed through Geographical Information and overlayed with additional visual information to create an effective approach to research and interpretation. Exploring different textures and gradients can then cradle parametric values in stylistic art forms that become diverse and informative.

Geometric shapes can be applied and extruded through either portion of the evolved surface to show landforms in new ways of abstract methodology. This allows parametric modeling to have more possibilities in the execution of both analytical and ideological theses.

ABSTRACT LANDFORMS Higher Values

THIS PLACE MATTERS Baker Proper & Great Basin National Park • Baker, NV, U.S.A.

The contrast between urban, suburban, and rural has given the world an unmistakably large range of different environments that we can explore, visit, and live in. A city can be an urban fabric that allows built form to be carried out in a vertical fashion as opposed to a rural setting that may spread outwards but with an entirely different behavior. Many rural locations are much more community-based and the demands are grouped into catagories that rely on small scale preservation. Places that are unique in the way that they carry out life and places where connecting to your neighbors every day, exists inbetween the large social centers that we call cities. Rural developments or villages and towns are all unique in their own respects, but the importance of these places is something that can often be Movement.

overlooked. The culture and character of these communities is worth noting in terms of importance and adequacy. One such community is called Baker, Nevada. Through the processes of town meetings, it wasn’t too difficult to notice that the representatives of this community felt that they were often left out. Through making connections from the natural beauty of the surrounding areas to the locality of Baker, configuring a strategic plan to shine light on this unforgettable place quickly became the premise for combining previously known ideas with new ones. Just down the road is Great Basin National Park a mildly popular attraction. With Baker as the only point of entry to the long climb up the mountain range, creating an effective Gateway to this National Park was key in drawing more attention to the community and exploration thereof.

RESTORING A DREAM The Historic West Las Vegas • Las Vegas, NV, U.S.A.

In the City of Las Vegas, Nevada, there are numerous iconic locations located throughout the very core of both it’s foundation and it’s respective metropolitan area. Multi-million dollar casinos, which have focus primarily on gaming and tourism, shine brightly alongside their towering hotel counterparts above the world-famous ‘Strip.’ Downtown has a much more vintage approach and appriciation than the ‘Strip,’ but still maintains a similar reputation to the hotel & resort corridor located on Las Vegas Boulevard. Although this type of reputation has somewhat set the standard on what attracts visitors to the Las Vegas Valley, people in adjacent neighborhoods to Downtown LV, seek to be noticed and to be heard. One such neighborhood, located directly Northwest of

Downtown, goes by the name of “The Historic West Las Vegas.” A shortened and more commonly used name is “The Historic Westside.” A neighborhood just as rich in culture as it is in life, The Historic Westside was once filled block to block with thriving development, homes, and businesses. Icons such as The Moulin Rouge contrasted with The Historic Westside School and let this neighborhood thrive with popularity in the mid to late 20th century. Although the years have crept by one by one and shown a physical toll on this lavish gem, many residents and visitors seek to bring back those glorious days yet again. As a collaborative effort in a studio comprised of Architects & Landscape Architects, generating this amount of forward initiative on constructing a new, ‘One Hundred Plan’ and bringing back the beautiful soul of ‘The Historic Westside’ was only the beginning.

Taking up an even smaller percentage than vegetation, our water supply cannot realistically support our growing urban areas.

In urban areas of the valley, areas with large amounts of vegetation appear to be golf courses or parks.
