“gutterspace” is reclamation project inaugurated by a man named Jack Gasnick,

This is how Anthony describes Gasnick’s project:
In the early 1970s—unbelievably, given how influential Gordon Matta-Clark has become in the last few years—Gasnick began buying and collecting “gutterspace,” or small slivers of land left over from zoning or surveying errors. He said that after a little while he couldn’t stop: “It’s like collecting stamps; once you’ve got the fever, you’ve got the fever.”
Accordingly, Gasnick “bought a slice in Corona just behind Louis Armstrong’s house,” Urbablurb continues, “a piece near Jamaica Bay where he once filled a pail with sea-horses, and yet another adjacent to the Fresh Kills landfill where he claims an abandoned sea Captain’s house still stood.” Gasnick then cultivated small patches of parkland and wilderness within those areas—a micro-wilding of the metropolis, one site at a time: “On the weekends, he would sometimes drive out to the tiny parcels and help the milkweed and laurel grow, tend to the turtles, and sit down for a picnic. ‘This jump of mine from flower pot to apple tree bears witness to the fact that it doesn’t cost much for an apartment-living guy to get a share of the good environment,’ he wrote in 1974. To be exact, it cost between $50 and $250. But the taxes he had to pay were enough of a hassle that he gave away (or otherwise lost track of) all the pieces by 1977.”
He “lost track” of them! The mind reels at the possibility that there is still a distributed Jack Gasnick estate somewhere, peppering the streets and gutters of New York City.
As Anthony suggests, this all has an uncanny parallel in Gordon Matta-Clark’s Fake Estates project. From Cabinet magazine:
In the early 1970s, Matta-Clark discovered that the City of New York periodically auctioned off “gutterspace”—unusably small slivers of land sliced from the city grid through anomalies in surveying, zoning, and public-works expansion. He purchased fifteen of these lots, fourteen in Queens and one in Staten Island. Over the next years, he collected the maps, deeds, and other bureaucratic documentation attached to the slivers; photographed, spoke, and wrote about them; and considered using them as sites for his unique brand of “anarchitectural” intervention into urban space.
So who is Jack Gasnick, that minor New Yorker who once “bought strange-shaped lots in every borough,” as the New York Times reported back in 1994, when Gasnick was still alive and 74 years old, and who once claimed to fish in the basements of Manhattan? Who knows.
