The Greatest Grid

We were recently sent a copy of The Greatest Grid: The Master Plan of Manhattan 1811-2011, the companion book to the exhibit of the same name at the Museum of the City of New York.

The book is richly illustrated with images from the show, including a fold-out copy of the original Commissioners’ Plan of 1811, which gridded Manhattan into streets and avenues up to 155th Street. Like the exhibition, the book tells the story of New York’s development from the era before the grid, through the city’s explosive growth in the mid-19th century and the development of the Upper East and Upper West Sides, and on to today. The material is at its strongest in the era between 1811 and 1900. The Greatest Grid features many detail maps, including some of the Randel Farm Maps, which remain among the most valuable insights into early 19th-century New York. Created by John Randel, the key surveyor of the Commissioners’ Plan, the farm maps show property lines, topographical features, and other key details at a scale of 100 feet to the inch. Noted Manhattan chronicler I.N. Phelps Stokes called them "the most complete and valuable topographical record of the period that exists."

Also revealing are photographs from later in the century that show just how long it took the city to expand into the grid that Randel had laid out. The photo above is the view looking north from the Dakota apartments, ca. 1890. The only major structure visible is the American Museum of Natural History, which had opened a few years earlier.

The Greatest Grid, skillfully edited by NYU Urban Studies professor Hilary Ballon, is packed with nuggets of information—what spurred the development of a grid plan; why Broadway works against the grid; how the area north of 155th Street faced unique topographical information. Some things are given short shrift—we would have liked more information on the Flatiron Building, for instance, or the development of Times Square—but these are minor quibbles. This is a title well worth owning for anyone who appreciates Manhattan’s past and wants to explore it in greater depth.

(And to plug our own book for a minute—it really does make an excellent companion to Inside the Apple, amplifying and illustrating many of the points we make.)

The Manhattan Street Grid Turns 200

Readers of Inside the Apple know that we are big fans of the Manhattan street grid, in part because it has made the city so easy to navigate on foot. Today, the grid plan--technically the "Commissioners’ Map and Survey of Manhattan Island"--turns 200 years old.

As we write in Inside the Apple:

With the population rapidly increasing and without any plan for regulating property sales and population growth, it seemed very possible that the city would simply collapse underneath its own weight, with too many people crammed into the area of the city below Chambers Street but not enough food, water, or sanitation to go around. 

The grid plan was overseen by a commission headed by Gouverneur Morris, the eminent politician who’d written the preamble to the Constitution. The survey itself was carried out by John Randel, Jr.; he and his team walked out every block of the city from Houston Street to 155th Street in Harlem, charting over 2,000 city blocks in all. It was enough room, as was noted at the time, “for a greater population than is collected at any spot this side of China.”

The goal was to create a regular pattern of east-west streets; along the avenues, exactly twenty of the blocks made up a mile. In turn, these blocks could be divided into regular lots, 25 feet wide by 100 feet deep. Each lot would back up precisely to its neighbor, with no room behind for service alleys or carriageways. Not only did eliminating alleys allow for bigger, more desirable lots, it reflected the reality that very few in New York would ever have the means to own a horse and carriage. Thus, there was no need for rear stables.  

As so few people had access to horses and carriages, the Commissioners’ Plan reinforced that New York was a city for walking. The plentiful east-west streets connected the two rivers where most commerce took place, with the wide north-south avenues designed for transporting goods and people over longer distances. Until the opening of the subway in 1904, the grid served this original purpose well. Even with the coming of horse-drawn omnibuses, trolleys, street cars, and private vehicles, New York was simply easier to walk, and the vast majority of the city’s workers lived within relatively easy walking distance of their jobs.

Yesterday's New York Times had a few good articles about the grid, including an interactive feature where you can compare Manhattan today with Randel's 1811 plan, which is hours of fun.
