The High Line is an elevated railroad reclaimed as an extraordinary public space, a connector of neighbourhoods and a new model for the ‘greening’ of the urban environment. It is creating a new way of seeing the city, is recognised as an icon for innovative design and sustainability and is an inspiration to other cities – proof of the dramatic change that landscape architecture can have on the quality of life in cities.
The goal was not to excessively modify the park with intricate designs but to enhance the current setting and create an engaging experience, a segmented stroll, and a dreamlike voyage within the city. In this endeavour, conservation and innovation unite by repurposing the existing framework into an appealing, unique recreational facility and public walkway.
Before developing the new landscape on the High Line, each structure element underwent examination and treatment to ensure its structural integrity. As individual rail sections were removed, they were labelled and documented to facilitate their reintegration as planting components in their original positions at a later stage.
Drawing inspiration from the untamed landscape that emerged after the line was abandoned, the team developed a paving system that promotes natural growth. This results in a “pathless” landscape. As explained by DS + Renfro, the High Line’s surface is transformed through a combination of agriculture and architecture, known as “agri-tecture”, into distinct paving and planting units. These units are arranged along the 1.5-mile stretch in various gradients, ranging from 100% paving to 100% lush, vegetated biotopes. This undefined and unobtrusive setting enables visitors to wander and enjoy the park according to their preferences.
The High Line is a bold urban revitalisation initiative that embodies the principles of preservation and recycling. This multifaceted project holds political, ecological, historical, social, and economic significance. Thanks to the efforts of two local residents, it serves as a symbol of community activism and provides a 6-acre green oasis in the city’s core. By repurposing a disused rail line into a vibrant public space, it also serves as a gathering spot for both locals and tourists, showcasing the revenue-generating potential of public spaces and promoting economic growth.
The half-mile Section 2 of the High Line turns infrastructure into green space, mitigating the urban heat island effect and fostering diverse habitats. Over 300 species, primarily native to the area, were carefully chosen for this unique environment. It incorporates green-roof technologies and open-joint pavement to help with water management, reducing the need for irrigation. Recycled materials, such as reclaimed wood, steel, and local aggregate for precast concrete, are extensively used.
Energy-efficient LED lighting illuminates the park, while sustainably-sourced food is available at concession stands. Additionally, a range of free educational programs are offered to engage the community.
The High Line’s connection to the city sets it apart and gives it a distinct strength. It serves as a continuous passage through diverse urban scenery. The various building styles and their interaction with the High Line are coupled with the thoughtfully arranged paths, offering views of the Hudson River, local streets, and iconic city landmarks. Altogether, they provide an unmistakably New York experience, adding to its allure. The High Line is not just a destination but also a journey, reviving the concept of promenading in the context of urban park experiences.
