The Commissioners' Plan of 1811 was the original design for the streets of Manhattan above Houston Street and below 155th Street, which put in place the rectangular grid plan of streets and lots that has defined Manhattan on its march uptown until the current day.
These streets do not run exactly east–west, because the grid plan is aligned with the Hudson River, rather than with the cardinal directions. Thus, the majority of the Manhattan grid's "west" is approximately 29 degrees north of true west; the angle differs above 155th Street, where the grid initially ended.
Since the spacing of streets in grid plans varies so widely among cities, or even within cities, it is difficult to generalize about the size of a city block. Oblong blocks range considerably in width and length. The standard block in Manhattan is about 264 by 900 feet (80 m × 274 m).
A grid plan from 1799 of Pori, Finland, by Isaac Tillberg. The city of Adelaide, South Australia was laid out in a grid, surrounded by gardens and parks. In urban planning, the grid plan, grid street plan, or gridiron plan is a type of city plan in which streets run at right angles to each other, forming a grid. [1]
When this plan succumbed to political squabbles and landowner demands, the city appealed to the state to dictate a design. [41] The result was the Commissioners' Plan of 1811, setting out the street grid of Manhattan above Houston Street. "In general," the commissioners resolved, everything "should be rectangular."
The only known image [1] of John Randel Jr.; painted by an unknown artist, probably Ezra Ames. [2]John Randel Jr. (1787–1865) was an American surveyor, cartographer, civil engineer and inventor from Albany, New York who completed a full survey of Manhattan Island from 1808 to 1817, in service of the creation of the Commissioners' Plan of 1811, which determined that New York City – which ...
Manhattan's street grid is oriented 29 degrees clockwise from true north, [61] and the real-time map uses an orientation that follows Manhattan's street grid rather than the cardinal directions. However, the mobile version of Google Maps would not allow map rotation. [51]
An 1807 grid plan of Manhattan. The history of New York City's transportation system began with the Dutch port of New Amsterdam.The port had maintained several roads; some were built atop former Lenape trails, others as "commuter" links to surrounding cities, and one was even paved by 1658 from orders of Petrus Stuyvesant, according to Burrow, et al. [1] The 19th century brought changes to the ...
