As part of the third stage of his work, Randel intended to create an extremely large map of the city, at an unprecedented scale. This has been a part of the agreement between Randel and the Common Council in 1812, but had been forgotten by all except Randel. Somewhat peeved to be reminded of it six years later, the council nonetheless honored the contract, and officially commissioned Randel to make his map. This was done by way of by colored "Farm Maps" made at a scale of that overlaid Manhattan's natural topography with the intended grid. When put together, the Farm Maps made a map of the city about long. It took Randel and his wife Matilda two years, from 1819 to 1820, to finish the maps, working from their new home, having moved to Orange, New Jersey. He needed, asked for, and received an extension from the Common Council to complete the task, and even then he did not quite make the deadline, delivering the last maps in September 1820, about four months late.
