The 12-foot-long strip of concrete operating by way of a new park in Shanghai is one clear remnant of the land’s earlier and radically totally different life. Initially laid in 1948, this line of concrete was as soon as a part of a lengthy, flat runway for town’s Longhua Airport. After it closed in 2011 and a district-scale city redevelopment venture started rising alongside its edges, the concrete runway went from being a essential piece of transportation infrastructure to a huge and seemingly ineffective relic.
What’s risen as a replacement over the previous decade is a new central park for the rising city district alongside the Huangpu River. Designed by the panorama structure and planning agency Sasaki, Xuhui Runway Park has changed the airport’s footprint whereas conserving its historical past alive. “We deliberately preserved this row of concrete,” says Dou Zhang, director of Sasaki’s Shanghai workplace, “to recollect the previous but additionally reuse the previous materials.”
This is among the newest examples of outdated transportation infrastructure being reborn into energetic public areas. New York’s High Line and Chicago’s 606 remodeled disused rail strains into metropolis altering parks, and cities like Seoul, South Korea, have taken old freeway overpasses and turned them into surprising pedestrian corridors. When Shanghai’s former airport closed, it grew to become a massive clean slate prepared for reinvention.
The park, just like the runway earlier than it, is lengthy and linear, one thing Sasaki selected to rejoice reasonably than cover. Zhang says the positioning earlier than development was “relentless” in its measurement and straightness. “Once we have been structuring our park and the spatial design, we tried to emphasise that linear feeling,” she says. Strolling paths lower straight down the 36-acre website, and a sequence of waterways, constructed wetlands, and rain gardens additionally type stripes by way of the area. The preserved width of runway and chunks of the unique concrete that was torn up throughout development make up strolling routes from finish to finish.
The location’s flatness additionally needed to be reckoned with. “That’s an alternative, and it’s additionally a constraint as a result of there’s little or no land type and topography,” says Mark Dawson, a principal at Sasaki and coleader of the venture with Zhang. “That must be interpreted in a method which you can scale it all the way down to a human degree, the place you and I can occupy the area and never be overwhelmed by the dimensions of airports.”
The design breaks up the flatness by integrating refined modifications in topography, with sunken areas that type backyard areas and an entrance to a new subway line constructed beneath a part of the positioning, in addition to barely angled walkways that should evoke the takeoff and touchdown of a airplane. Cafe buildings are scattered all through the park, as are playgrounds and sports activities fields.
Water options are a distinguished component of the park, which integrates an present canal system but additionally creates a sequence of rain gardens and constructed wetlands, which filter runoff from the road earlier than it enters waterways that connect with the close by river. Zhang says a lot of this pure filtration is made potential by the park’s use of 100% native crops, which she says, is uncommon in Shanghai. “You see the identical factor in every single place. It turns into an simple palette for folks to make use of as a result of [non-native plants] are largely obtainable within the trade. However their ecological worth is restricted,” she says.
As city regeneration continues within the surrounding district, the position of stormwater cleansing is more likely to develop into much more vital. Excessive-rises and towers at the moment are being constructed on either side of the runway park, creating extra residences, places of work, and industrial makes use of within the space.
That’s additionally creating a built-in person base for the park itself. Because it opened late final yr, the park has established itself as a valued public area. Playground tools in some components of the park has already had to get replaced on account of overuse.
“I’ve simply been overwhelmed by how the group has embraced this very linear park and open area as being their entrance yard,” says Dawson.
The park and the rising neighborhood round it are already interweaving. In comparison with what it was like to face on the closed runway earlier than the park was constructed, Zhang says, the park has develop into extra human-scaled. “An individual felt very small,” she says. “However now a lot of buildings are up, the streets are up. The sensation is totally different.”
