-
My dream is to build the world's first
-
underground park in New York City.
-
Now, why would someone want
to build an underground park,
-
and why in New York City?
-
These three tough little buggers
-
are, on the left, my grandmother, age five,
-
and then her sister and brother,
-
ages 11 and nine.
-
This photo was taken just before they left
-
from Italy to immigrate to the United States,
-
just about a century ago.
-
And like many immigrants at the time,
-
they arrived on the Lower East Side
-
in New York City
-
and they encountered a crazy melting pot.
-
What was amazing about their generation
-
was that they were not only building new lives
-
in this new, unfamiliar area,
-
but they were also literally building the city.
-
I've always been fascinated by those decades
-
and by that history,
-
and I would often beg my grandmother
-
to tell me as many stories as possible
-
about the old New York.
-
But she would often just shrug it off,
-
tell me to eat more meatballs, more pasta,
-
and so I very rarely got
-
any of the history that I wanted to hear about.
-
The New York City that I encountered
-
felt pretty built up.
-
I always knew as a kid that I wanted
-
to make a difference, and to somehow
-
make the world more beautiful, more interesting
-
and more just.
-
I just didn't really know how.
-
At first, I thought I wanted to go work abroad,
-
so I took a job with UNICEF in Kenya.
-
But it felt weird to me that I knew more about
-
local Kenyan politics than the
politics of my own hometown.
-
I took a job with the City of New York,
-
but very quickly felt frustrated
-
with the slowness of government bureaucracy.
-
I even took a job at Google,
-
where very fast I drank the Kool-Aid
-
and believed almost wholeheartedly
-
that technology could solve all social problems.
-
But I still didn't feel like I was
making the world a better place.
-
It was in 2009 that my friend
-
and now business partner James Ramsey
-
alerted me to the location of a pretty spectacular site,
-
which is this.
-
This is the former trolley terminal
-
that was the depot for passengers
-
traveling over the Williamsburg Bridge
-
from Brooklyn to Manhattan,
-
and it was open between 1908 and 1948,
-
just around the time when my grandparents were
-
living right in the area.
-
And we learned also that the site
-
was entirely abandoned in 1948.
-
Fascinated by this discovery,
-
we begged the authorities to draw us into the space,
-
and we finally got a tour,
-
and this is what we saw.
-
Now, this photo doesn't really do it justice.
-
It's kind of hard to imagine the unbelievably magical
-
feeling that you have when you get in this space.
-
It's a football field of unused land
-
immediately below a very crowded area of the city,
-
and it almost feels like you're Indiana Jones
-
on an archaeological dig,
-
and all the details are all still there.
-
It's really pretty remarkable.
-
Now, the site itself is located at the very heart
-
of the Lower East Side,
-
and today it still remains one of the most
-
crowded neighborhoods in the city.
-
New York City has two thirds the green space
-
per resident as other big cities,
-
and this neighborhood as one tenth the green space.
-
So we immediately started thinking about how we
-
could take this site and turn it into something
-
that could be used for the public,
-
but also could potentially even be green.
-
Our plan, in a nutshell,
-
is to draw natural sunlight underground
-
using a simple system that
harvests sunlight above the street,
-
directs it below the city sidewalks,
-
and would allow plants and trees to grow
-
with the light that's directed underneath.
-
With this approach, you could take a site
-
that looks like this today
-
and transform it into something
-
that looks like this.
-
In 2011, we first released some of these images,
-
and what was funny was,
-
a lot of people said to us, "Oh, it kind of looks
-
like the High Line underground."
-
And so what our nickname ended up becoming,
-
and what ended up sticking,
-
was the Low Line, so the Low Line was born.
-
What was also clear was that people really wanted
-
to know a lot more about how the technology
-
would look and feel,
-
and that there was really much more interest in this
-
than we had ever thought possible.
-
So, like a crazy person, I decided to quit my job
-
and focus entirely on this project.
-
Here is us with our team
-
putting together a technology demonstration
-
in a warehouse.
-
Here's the underbelly of this solar canopy
-
which we built to show the technology.
-
You can see the six solar collectors at the center there.
-
And here's the full exhibit all put together
-
in this warehouse.
-
You can see the solar canopy overhead,
-
the light streaming in,
-
and this entirely live green space below.
-
So in the course of just a few weeks,
-
tens of thousands of people came to see our exhibit,
-
and since that time, we've grown
-
our numbers of supporters both locally
-
and among design enthusiasts all over the world.
-
Here's a rendering of the neighborhood
-
just immediately above the Line's site,
-
and a rendering of how it will look
-
after major redevelopment that is coming
-
over the course of the next 10 years.
-
Notice how crowded the neighborhood still feels
-
and how there's really a lack of green space.
-
So what we're proposing is really something that will
-
add one football field of green space
-
underneath this neighborhood, but more importantly
-
will introduce a really community-driven focus
-
in a rapidly gentrifying area.
-
And right now, we're focusing very closely
-
on how we engage with the City of New York
-
on really transforming the overall ecosystem
-
in an integrated way.
-
Here's our rendering of how we would actually
-
invite people into the space itself.
-
So here you see this iconic entrance
-
in which we would literally peel up the street
-
and reveal the historical layers of the city,
-
and invite people into this warm underground space.
-
In the middle of winter, when it's
absolutely freezing outside,
-
the last place you'd want to go would be
-
an outdoor space or outdoor park.
-
The Low Line would really be a four-season space
-
and a respite for the city.
-
So I like to think that the Low Line actually brings
-
my own family's story full circle.
-
If my grandparents and my parents were really
-
focused on building the city up and out,
-
I think my generation is focused on reclaiming
-
the spaces that we already have,
-
rediscovering our shared history,
-
and reimagining how we can make our communities
-
more interesting, more beautiful and more just.
-
Thanks.
