The NYC Grid: Retracing Surveyor John Randel Jr's Footsteps

1.0 NY LS/PE CE Hour


200 years ago the Commissioners of 1811 (Gouverneur Morris, John Rutherfurd and Simeon De Witt) devised a plan for the development of the City of New York from its colonial center up through the open Manhattan Island. Their plan, a grid of streets and avenues, imposed a rational structure across farmland, forests and marshlands. John Randel, Jr, the commissioners' chief engineer and surveyor, surveyed rural Manhattan and placed a marker at the intersection of every street and avenue, from the Hudson River to the East River, from 1st Street to 155th Street.

 

The grid is plain to see today, but street grading and two centuries of dense development most likely destroyed all of Randel's markers. Finding actual markers as placed by the original surveyor is not only the gold standard for surveyors, but also a valuable sliver of our history. Are there any left? We will discuss the collaborative effort to recover and verify Randel's markers in an area where the grid was laid out but not constructed - Central Park.

 

Seminar Goals and Objectives

  1. Explain the history of the Manhattan Grid
  2. Identify the sources of historical records used
  3. Describe the methods used to recover boundary markers
