At first, this looks like a perfectly normal map of New York City.

You zoom in and there's Broadway, and Bowery.

But then you realize that the map is...wrong.

Streets run diagonally and the map adds land beyond the edge of the island.

And this one — the one with the perfect grid we know — was basically what we ended

Today Manhattan has a grid so perfect that the way the sun shines through it is a hashtag

But these grids were not all about beautiful design, or even making it easier to find your

way around when you come up out of the subway.

The real reason one of these plans made it and the other didn't?

It says something about how — and why — all cities develop the way they do.

When William Penn designed Philadelphia in 1681, he wanted to make an ideal city.

His intentions reflected American ideas and his Quakerism.

The lines on his grid weren't just right angles, they were morally right angles.

He wanted to preserve a sense of a country town using common areas and gardens.

In 1733 in Savannah, Georgia, the Oglethorpe Plan was influenced by the Enlightenment,

with an emphasis on balance and limits on the grid's growth.

That resulted in a grid too, but with an elegant design including common squares where all

could congregate, and commons limiting the grid plan's reach.

Pierre L'enfant's 1791 plan for Washington, DC, was even more ambitious, and though the

city deviated from his design, some flourishes survived, like diagonal avenues sliced across

the city, circles to vary the grid's monotony, and grand squares for each of the then-15

This 1767 map shows the chaotic curved streets and irregularities that marked the nearly

What little order that had developed was largely private and subject to frequent change.

This 1776 map shows a planned grid with a large square.

That square belonged to the Delancey estate (Delaney was a typo).

Because the prominent New York family supported the British during the Revolutionary War,

the city confiscated their land after the war.

This 1789 map shows what happened to their planned square.

New York could have been stuck with this chaos.

But as the 1800s rolled around, it couldn't afford to be much longer.

It's tough to know New York's exact population before 1800, but the trend was clear - massive

growth, more than doubling between 1770 and 1790.

Outbreaks of yellow fever that spread up and down the East Coast heightened the urgency

And that is where this failed plan comes in — in 1797 the city hired architect Joseph

Mangin and surveyor Casimir Goerck to map New York.

The plan showed the city as it “should be,” not as it was.

They widened janky streets and even added to the waterfront — they proposed something

graceful, but the city needed something fast — so their plan was rejected.

In 1807, the state established a new commission to create a workable plan,

In this map, this color shows the settled land, and this color shows the projected areas

In their official report, they said they'd planned for “a greater population than is

collected at any spot on this side of China.”

They had debated “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

Basically, did they want L'enfant's Washington or a uniform grid?

They decided that, “right-angled houses are the most cheap to build and the most convenient

The effect of these plain and simple reflections was decisive.”

The grid did that without screwing up existing property-lines.

The grid seems orderly to us, but this order was in service of cheapness and efficiency.

Landscape architect Frederick Olmsted designed that park and many other public spaces.

In a laundry list of criticisms of the New York City grid, he said that, “Still other,

and perhaps even graver, misfortunes to the city...could have been avoided by a different

The dream plan would have been more refined, but this?

In 1811, New York's values were build, build, build.

Without development, you just have the sun.

Hey that's it for this episode about grids.

I'm about to read some comments from the previous episode of this Almanac: Road trip

“Edison was walking around calling Harvey Firestone dude.”

Uh yeah, he was, and also one thing I wasn't able to mention was that Edison was really

hard of hearing at this time of his life, so basically every time you wanted to talk

to him you had to yell directly in his ear.

“A 2019 version would probably be in a Tesla with Elon Musk, Bill Gates, and Warren Buffet

I will see you next week, and I'm actually going to be driving in this episode.
