The Empire City Rises · 1811

The Commissioners’ Grid

Three men and a young surveyor drew a relentless rectangle over Manhattan, 12 avenues and 155 streets, and explained that right angles were simply cheaper to build. It is why the city looks the way it does.

The facts

The law
An 1807 state act gave three commissioners near-absolute power over Manhattan’s streets
The commissioners
Gouverneur Morris, Simeon De Witt, and John Rutherfurd
The surveyor
John Randel Jr., who placed over 1,500 marble markers and iron bolts across the island
The plan
Adopted 1811, a grid of 12 avenues and 155 cross streets, with almost no squares or diagonals
The reasoning
The commissioners said "strait sided and right angled houses are the most cheap to build, and the most convenient to live in"
The exception
Broadway, an old road that predates the grid and cuts across it

In 1811, three commissioners and a young surveyor decided what Manhattan would look like forever. A state law had given them near-total power over the island’s streets, and rather than the circles and grand diagonals of Washington or Paris, they chose a relentless rectangle: 12 numbered avenues, 155 numbered cross streets, almost no squares, parks, or angles. Their reasoning, written plainly in their official remarks, was money: a city is made of houses, and "strait sided and right angled houses are the most cheap to build, and the most convenient to live in." The surveyor John Randel Jr. spent years staking it out, planting over 1,500 marble markers through farms and over rock, and getting himself arrested for trespass by furious landowners. The one great exception is Broadway, an old road older than the plan, which cuts the grid on a diagonal and opens the squares, Union, Madison, Herald, Times, where it crosses. The grid turned raw Manhattan into uniform, sellable lots, and the city has been built on it ever since.

In their words

The event in the voices and documents of the people who were there. Every source links out so you can check it.

  1. Document

    The blunt justification for a plain rectangle over anything ornamental: cheapness and convenience over beauty.

    A city is to be composed principally of the habitations of men, and that strait-sided and right-angled houses are the most cheap to build and the most convenient to live in.

  2. Document

    A direct swipe at the baroque diagonals of L’Enfant’s Washington. They considered it and chose against it.

    Whether they should confine themselves to rectilinear and rectangular streets, or whether they should adopt some of those supposed improvements by circles, ovals, and stars, which certainly embellish a plan, whatever may be their effect as to convenience and utility.

  3. Memoir

    Randel spent years staking the future grid across private farms. The angry landowners had him arrested for trespass; a colonel kept posting his bail.

    I was arrested by the Sheriff, on numerous suits instituted against me as agent of the Commissioners, for trespass and damage committed by my workmen, in passing over grounds, cutting off branches of trees, &c., to make surveys.

  4. Document

    The grid’s most famous critic, the co-designer of Central Park: every block is interchangeable, so no place is special.

    If a building site is wanted, whether with a view to a church or a blast furnace, an opera house or a toy shop, there is, of intention, no better a place in one of these blocks than in another.

  5. Document

    The state, not the city, handed three men near-absolute authority. It is why the grid could override every landowner in its path.

    An 1807 state act gave the three commissioners "exclusive power to lay out streets, roads, and public squares" on Manhattan, of whatever "width, extent, and direction" they thought best.

  6. Document

    The grid’s great exception is not a planned flourish. It is a road the planners could not erase.

    Broadway is older than the grid: an Indigenous trail that became the colonial Bloomingdale Road. The commissioners tried to straighten away its diagonal above 14th Street and failed, which is why it slashes across the grid and opens the squares at Union, Madison, Herald, and Times.
