The success of New York’s High Line park has inspired urban planners around the globe to refashion unused infrastructure into soaring parks. And now, it has inspired something close to its opposite: The LowLine, an underground park whose fundraising drive is kicking off today on Kickstarter. If successful, it might eventually become the most massive project ever begun by the crowd-funding website. For now, the visionaries behind the LowLine are hoping to raise $100,000 to create mock-ups of their technology that will bring natural light into the space.

That technology was conceived by the LowLine’s founders, Dan Barasch and James Ramsey, and would use fiber optic cables to fill the subterranean space with natural light and living plants. The proposed site is an unused and long neglected 13-acre former subway stop on Delancey Street, built in 1903 in New York’s Lower East Side. While they imagine the park serving the local community it is found in, they also imagine this park becoming a model for the reappropriation of other, long-forgotten gems found in cities all over the world. It’s the kind of space that childhood daydreams are made of.

“I was talking to my mom the other day,” said Barasch, “and she asked me how long we’d actually been working on this project. … It’s only been really two to three months of taking this more seriously and having it not just live in our heads. We’re really just three months into this. But the speed with which this project has gained momentum is astonishing.” Ramsey agrees and chimes in, “There’s a collective cultural longing that is making this project strike a chord. We are all feeling weary of cheap, new, modern. There is a throwback to previous eras of slow, local, community. “

But the project isn’t simply an attempt to recapture the past. It is a conflation of a few really big trends, and some almost sci-fi, futuristic technology.

Ramsey, a former NASA satellite engineer and current principal at RAAD studios, has developed a series of fiber-optic tubes specifically for this project. The use of this kind of green tech is usually confined to massive projects in far away places, experiments on the edge of actually being built. Ramsey is adamant that it’ll work, and will make accessible what has previously been hidden in the depths. “That process of discovery, of finding something like this that was lurking beneath the surface, was something that I found so compelling, that I felt like, this experience, this space, was something that needed to be shared with more people. One of the easiest ways to get people to consider a space like this would be to introduce natural sunlight,” says Ramsey.

“In the early days, urban design was something that happened and was sort of presented. We’ve learned a lot of lessons from the community-centered approach. It’s a sign of our times, that building and design development is something the community thinks about a lot more,” says Barasch.
