Shane KimbroughIt's no accident that Metro Detroit--a region historically apathetic to organized urban planning--ended up with a neat grid of roads set one mile apart. But there is a deeper order and complexity to the system beyond a convenient grid. Its origins lie deep in the early history of the United States, and is one of the boldest utopian social engineering experiments ever proposed by its founders.
The system would work like this: Once a treaty extinguished Native American ownership of a given area, the land was to be surveyed. A surveyor would begin by establishing a "Point of Beginning" or "Initial Point" in a more or less arbitrary location in a new territory. From there, a Meridian (running north-south) and a Baseline (running east-west) would be drawn, becoming the axes along which square townships were to be established. Jefferson believed that these surveys should follow a new system of measurement using "geographical miles" (one second of one degree of the Earth's circumference, or 6,086.4 feet), and laying out townships measuring ten geographical miles on a side. But the final version of the Land Ordinance codified townships measuring only six miles on a side, and that conventional measurements would be used. Finally, each township was subdivided into thirty-six "sections" measuring one square mile each.

Hathi TrustThe Treaty of Detroit was signed several months later, ceding most of southeast Michigan to the US government, aside from a few designated Indian reservations. Native Americans were permitted to hunt and trap on this land until it was sold to private owners.

Edward Tiffin, Surveyor General of the Northwest Territory from 1815-1829, entered into a contract with surveyor Alexander Holmes on April 18, 1815, to establish the Michigan Baseline "due West from a point above Detroit." Holmes received permission to split the contract with his brother, Samuel. Tiffin also contracted with surveyor Benjamin Hough on April 28, 1815 to lay out "a true meridian line from Fort Defiance," which was also the beginning point of the Treaty of Detroit land cession. The Michigan Meridian was to coincide with the western boundary of the federally owned land.
Holmes' and Hough's contracts also specified how the military bounty land should be laid out. It would consist of ninety-six townships arranged in a rectangle measuring twelve townships tall by eight townships wide, centered directly over the baseline. Holmes was to outline the east forty-eight townships, and Hough had the west forty-eight. Other surveyors were contracted to subdivide the townships into one-mile sections.

Hough and Holmes, whose contracts required them to finish their work by January 1, 1816, had to move quickly. Rather than survey the baseline and meridian separately as originally planned, they teamed up at Fort Defiance to begin work on the meridian, with the intention of splitting up and focusing on their respective tasks upon reaching Michigan's interior.
The surveyors and their crews arrived at Fort Defiance, Ohio in late September 1815. Their first task was to carefully observe the movement of the North Star in order to calculate the exact deviation between magnetic north and true north, which was found to be 4°39' east. They also had to determine, then and there, how far north the Michigan Baseline should be. In order to ensure that the military bounty land was not interrupted by Lake Erie or the Ohio border, the surveyors calculated that the baseline should run seventy-eight miles north of Fort Defiance. In other words, the spot where they began the survey of the Michigan Meridian at Fort Defiance was the southwest corner of the (theoretical) thirteenth township south of the baseline.

The first page of Hough's field notes, at the genesis of the Survey of Michigan, begins:
Friday September 29th 1815 - West boundary T.13 R.1 South
Commenced the Meridian, or Indian boundary line, Beginning at the Mouth of the Great Auglaize river, and run by the true meridian due North (the Variation being 4°,39' East) crossing the Miami of Lake Erie

Each surveyor required several assistants, including chainmen, an axman, a rodman, a counter, and a cook. The surveyors marked every half mile with a wooden post set firmly in the ground. Every tree close to the line was marked with a "blaze"--a smoothed area made by chipping away bark. Trees standing directly on the line were marked with deep horizontal hacks. And the entire process was carefully documented in the surveyors' field notes. These notes also included the locations of bodies of water, Indian paths, and other landmarks, as well as descriptions of the soil, topography, and vegetation.

Tuesday Johnson's Historical IndulgencesSurveyors and their tools, circa 1850.After just three miles, they came to Posey Lake. Establishing a theoretical line "through" the lake entailed moving around it along a carefully measured path and running calculations--a time-consuming process known as "meandering." As Hough approached the sixth mile east of the meridian, surveyor Thomas Evans stayed behind to begin subdividing the very first township of this tract, now known as Rollin Township, into one-square-mile sections. Evans later described this township as "very swampy and tedious to survey," and that, if the rest of the land was similar, "I shall not be able to finish it this Season." On the following day, Hough and his assistant, Allison Looker, separated in order to begin surveying the first and second range lines simultaneously.

detained me another full day in going around it—This lake is from half a mile to 3/4 of a mile wide, and about 3 or 4 miles long, but the difficulty in meandering round those lakes is beyond any thing you can conceive—From what I have seen this country is in no ways inviting—It is true there is some good spots; but a large proportion is either useless swamps, or poor and barren—From there, the surveyors' experience did not improve. Because they did not realize that 1815 had been a particularly rainy year, they were led to believe that Michigan was mostly covered in swamps.
On the sixth day, October 18, he continued the line east for only two miles, crossing the Great Sauk Trail less than half a mile before stopping on what is now the border between Canton and Van Buren townships. At this point there is a six-day gap in the field notes. Holmes probably followed the Sauk Trail to Detroit, where he and his men rested and stocked up on supplies, and where his brother, Samuel, was waiting to rendezvous with him.

The following day, October 24, witnessed an important event in the urban planning history of Detroit. This was the date when both Samuel and Alexander Holmes, while surveying their respective range lines northward, set the very first monuments on the Michigan Baseline. Alexander met the baseline at the exact corner where Farmington Hills, Livonia, Northville Township and Novi meet. The post set by Samuel now marks the intersection of Napier Road and Eight Mile Road. Eight Mile Road, of course, coincides with the Michigan Baseline, and in many places is called Base Line Road.



Archives of MichiganAlexander Holmes withdrew from the survey and rested in Detroit for a week and a half. "We have suffered almost every hardship, and encountered almost ever[y] difficulty that could be expected of mortals to endure," he wrote to Tiffin while recuperating in Detroit, "but amidst all have been bless'd with good health.—It is my intention not to quit until I finish, which I hope to accomplish before the 20th of next month."

continued at work, suffering incredible hardships, until both men and beasts were literally wore down with extreme sufferings and fatigue. The frost set in early, and the ice covered nearly the whole country, but broke through at every step, and the pack horses could not be got along with them.
In either case, Hough did return (at least briefly) in early 1816 to complete the few lines that included Michigan's Initial Point. Because of the flooding of the Portage River, he couldn't directly carry the meridian north to that location, but instead had to backtrack westward along the baseline. The point where Hough set a post in the earth to indicate the center of the survey of Michigan is today marked by a concrete monument and bronze marker.

Photograph by the author.Eight years after Hough established this point, surveyor Joseph Wampler was tasked with beginning a survey west of the meridian, after that land had been obtained from the First Nations. He began on the meridian twelve miles below the Initial Point and headed north. However, unlike his predecessors, he was able to cross the Portage River and continue along the meridian directly. In doing so, he found that Hough had made an error when locating Initial Point. Hough's post was 935.88 feet north of where it should have been. In the map below, notice that the survey lines based on Wampler's work (on the west) and the lines based on the work of Hough and Homes (on the east) tie in to one another south of the Portage River, but not north of it.

Tiffin's report led to a law passed by Congress in April 1816 substituting land in Illinois and Missouri to be used for military bounties instead.
This vast surveyed tract was simply to be sold to the public at a later date. But with Tiffin's damning report and the isolation of these two million acres in the middle of the peninsula, it seemed unlikely that the struggling territory could attract the settlers it needed.
