The location is thought to be (and by the way Mr. James Truex an
administrator at the Friends World College, a Quaker institute of
higher learning on Long Island, NY which I visited once, was a past
president of the Suffolk County Archaeological Association for a
number of years) wherever near the corner of Beekman and Pearl streets
the property, parking lot is bounded by them and Pearl and Water
Street, the original shoreline somewhere near Pearl street side. On
one corner lived American patriot Walter Bowne who became in his older
age, the Quaker Mayor of New York City. They were important in the
shipping and business of the South Street Seaport, the first regular
packet service to Liverpool, England started by them from there in
about 1819.

As survey techniques improved land descriptions changed orientation
and are laid out slightly different in succeeding official surveys.
There are whole "gores" in New England between properties and the ones
in New Jersey belong to an association of "Freeholders" from the
original settlers with power like the former Governor and EPA chief
Christine Todd Whitman. In New York State they auction them off a
surveyor told me trying to interest the adjoining holders in adding to
their property.

The documentation on this lot of land building is fairly descriptive
though depths are sort of reconstructed from nearby city borings,
construction and sometimes destruction permits. However, urban
landscapes tend to accumulate, with the age of steam I would assert
and the steam shovel giving rise to wholesale movements of large
amounts off site. Mr. Peck after which Peck Slip is named is one of
the first city benefactors to propose more land to be made and a Peck
Slip Market was once where the "slip" (where the Dutch would bring
there boats into the town) was filled and properties made, in response
to economic factors. One French observer wrote that it seemed the
Americans had solved their American Revolution unemployed soldier
problem as upwards of 5000 were employed in filing in and leveling the
former battlements, slips perhaps and sometime standing water. The
island was remarkably marshy in some places like the east side of
Canal Street west of Houston ("howston" they say here).

Basically, I'm not sure where it was, post 1750 or so there was alot of filling.
