The Manhattan street grid plan of 1811 -- both figuratively and literally -- defines the city. It has created its identity while prompting continuing debate about whether it’s the “greatest grid” or “one of the worst city plans.” Despite the endless fascination after 200 years and counting, the grid’s history and its effect on Gotham are still not fully understood. We aim to correct the record. Here, we introduce some key misconceptions and their corrections; in eight monthly installments, we will discuss each one in more detail.
The conventional wisdom is that the grid plan was created by John Randel, Jr., the chief surveyor for the commission charged with coming up with a future street plan, and who tirelessly trudged through the wilds of Manhattan in order to map it. But the truth is that Randel did not create the plan. While his efforts were Herculean, the plan derived not from Randel’s head, but rather was based directly -- and without acknowledgement -- on the work of late surveyor, Casimir Goerck, who had mapped out a large centralsection of rural Manhattan in the 1780s and 1790s.Randel was an employee of the Commissioners; it was they -- three venerable, nationally prominent men -- who chose to adopt and expand Goerck’s plan; Randel, a barely twenty-year-old Albany provincial, followed their instructions.
Myth #2: The Commissionersas Visionaries
The only record the Commissioners left for posterity was an eleven-page document outlining the basics of the map that gridded Manhattan from North (now Houston) to 155th Streets. The document, dubbed “Explanatory Remarks,”explains little of the Commissioners’thinking. Their personal writings practically ignore their work. Over the generations, great intention has been ascribed to the Commissioners that does not exist. Analysis of the Commissioners’ actions shows that the grid plan was not a “plan” so much as a convenience to satisfy a deadline. That is, not aplan but rather a “rush job”because the Commissioners demonstrated little interest in their responsibilities until the final months of their four-year term. Manhattan’s future was sealed with scarcely a discussion.
Myth #3: Aaron Burr
When it comes to Aaron Burr and his role in the history of New York City (as opposed to the nation), the best known story is that he created the Manhattan Company in 1799 to supply the city with much-needed fresh water, but used most of the money the company generated for his prime and secret purpose, to start a bank that is now JPMorganChase. The company’s notorious neglect of its monopoly water responsibilities subjected New Yorkers to four decades of fire and disease before the city completed its pioneering Croton Aqueduct, the first piece in New York’s now vast and iconic modern water supply. Little known is the pivotal role Burr played in events that led directly to the street commission that gave Manhattan its grid.
Myth #4: The Grid Plan Created Manhattan’s Small Lots
It is a general assumption that Manhattan’s standard lot size of 25’ x 100’ was part of the 1811 grid plan. This is not true. Like many details that were omitted, it said nothing about lot size. In fact, the 25 x 100 lot long predated the grid plan. Standardizationin lot size began during the Dutch colonial period and continued into the nineteenth century. 25’ x 100’ was found to be a size both most suitable for living and working in a small merchant town and at the limits of building technology. The tradition remained as the grid plan was implemented, especially as its 200’ blocks were conducive to two rows of 100’ lots.
Myth #5: The Grid Plan Leveled Manhattan
Images abound of small wooden houses perched atop lonely hills along 5th Avenue, as new roads obliterated natural Manhattan to make way for the grid. This has left the impression that Manhattan was flattened by the grid plan. But the truth is a bit subtler. Rather, implementation, in practice, was more of a "“smoothing" ”than a leveling. North of 14th street was a jagged stretch of hills and valleys; the former came down, the latter went up.The general elevation, though, remains the same as it was 400 years ago.
Myth #6: The Grid Plan Caused Too Much Density and Rampant Land Speculation
The grid plan in the nineteenth century became a symbol of the evils of hyper-dense, unsanitary living because critics argued that it encouraged poor urban health. However, as compared to the short and narrow blocks south of Houston Street, the larger blocks of the plan, may have, in fact, helped reduce population density. Another trope is that once the plan was set, greedy land speculators went on a tear -- driving prices up. But this is like blaming the automobile for traffic congestion; land price bubbles are a problem of human psychology, not maps.
Myth # 7: Static Manhattan, Part I
While it is true that the plan has forever set a rectangular city, it has demonstrated a large degree of flexibility and change over the years, and is not static like many believe. For example, Lexington and Madison Avenues, and Central Park were all added after the plan was first established. More broadly, a comparison of Manhattan from 1900 to the present shows a surprising evolution in block configurations.
Myth #8: Static Manhattan, Part II
When the Dutch first settled Manhattan, they began to fill in the shorelines. In fits and starts, Manhattan has been growing ever since. Today we tend to see Manhattan as a fixed island, but over the centuries it has changed its size to a considerable degree. Visions for its continued expansion have been proffered throughout the centuries; the future growth of the city may require implementing some of these visions and offer competing alternatives to the plan.
