It looks a bit odd.
From the interactive map accompanying Sam Roberts' March 20, 2011, New York Times article, "No Hero in 1811, Street Grid’s Father Was Showered With Produce, Not Praise."
I suppose some of John Randel's hand-drawn and colored maps are now on view at the just-opened Master Plan of Manhattan exhibit at The Museum of the City of New York.
The Times' interactive map is fun to play with. It allows the user to fade in and out of Randel's 1811 map of the proposed street grid and the grid as it now stands. Carl Schurz Park seems to be the latest layer to re-place the Gracy piece, the Gracy place.
