THE HIGH LINE, NEW YORK URBAN DESIGN SAAD BOUDESS GROUP: B HIGH LINE INTRODUCTION One of the most imaginative urban renovation projects is the conversion of the High Line, an abandoned elevated railway construction on Lower Manhattan's West-side into a public park. The transformation of the meatpacking district into one of New York's most popular neighborhoods would not have been possible without the impact of this one-of-a-kind urban park, the High Line. The story of how it came to be is remarkable: two young citizens with no prior experience in planning and development collaborated with their neighbors, as well as movements in horticulture and landscape architecture, to create a park that is now recognized around the world as a model for creatively designed, socially vibrant, and environmentally sound public space. Annually, about 8 million visitors are counted. The study will shed light on how the process works. This paper will try to elucidate the process of the execution of the High Line and the mechanism that has been used to transform and impact the neighborhood. The method of Urban catalyst has drawn a lot of attention in the architecture world, especially in the European and American continent. HIGH LINE HISTORY The 1.45Km High Line Park is an elevated park built on the former New York Central Railroad, often known as the West Side Line. It runs from Gansevoort Street to the northern edge of the West elevated park, passing through the Meatpacking District and Chelsea market area. The first phase of this park opened in 2009, followed by the second and third phases in 2011 and 2014, respectively, and the most recent addition to this park was phase 4 which opened in 2015. In 1847, the City of New York authorized the use of street level railroad parcels in downtown Manhattan's Westside to transport freight. It then hires for the sake of safety. However, due to a high frequency of incidents involving freight trains, the "Death Avenue" has been dubbed "Death Avenue". HIGH LINE DESIGN CONCEPT After a lot of debate and political opposition, there has been a new proposal consisted into building a new elevated highline with over 105 street-level railroads crossings. This was crafted by Robert Moses. Hence, the latter became a sync model of a transportation system built to accommodate its environment. The High Line is a vast yet attractive art deco masterpiece of industrial design. The geometric designs of the guard rails distinguish it. It is an extraordinary work of engineering and construction, made up of layers of steel and millions of rivets. The high line became a haven for homeless people, drug dealers, and prostitutes until two locals, Robert Hammond and Joshua David, founded the non-profit organization "Friends with the High Line." His former piece of municipal infrastructure had been transformed into 37foot-high linear gardens. The effort to save the High Line gathered traction after that. HIGH LINE DESIGN CONCEPT This urban redesign project was meticulously addressed by the design group, which was affiliated with the Friends of Highline, New Yorkbased Corner Field Operations landscape architects, down to the micro level, leading to the design of elements such as ramped elevated benches that represented the elevated line, walkways and planting beds revealing exposed train tracks, seeds and grasses evoking the primal wilderness that took over after the line was abandoned, and more. This location's landscaping followed the classic design approach of "scripting a path or a journey" (Trail of the Month, 2011). Despite the fact that the High Line cost $100,000 million to build, it has attracted $2 billion in private investment. HIGH LINE IMPACTS Connecting People For A Diverse City: Form, movement patterns and activities offer to success to connect people for a better neighbourhood experience as these 3 aspects provide safety from busy street, linkage from point to point that is easily accessible as well as gathering people with same interest. HIGH LINE IMPACTS Promote Sustainability For A Healthy City: Sustainability achieved from the 3 main aspects of urban structuring principles: form, movement patterns and activities. By making the abandoned trail track into walkable recreational space to decrease usage of vehicle, emission of CO2 can be reduced. The space was contextually designed to provide high accessibility to promote healthy city lifestyle. HIGH LINE IMPACTS Decrease Crime Rate For A Safer City: Crime rate is effectively reduced due to the effects of urban structuring principles directly. Transforming the function of Highline from negativity into positivity has successfully induced the usage of the space as recreational park and attracts local users, avoiding misuse of the trail track. High visibility at higher level enhance site safety. HIGH LINE CONCLUSION Opening new companies in West Chelsea and the High Line to a greater extent. Zoning modifications are pushing development along both 10th and 11th Avenues, which helps to preserve the "Art Gallery" identity. More research is intended to look into specific changes, such as the street base and avenue vase, to better understand the gratitude of influence travels parallel or perpendicular to the High Line, as well as how those elements interact with pedestrian flows.
