Burton became a city in 1972 to keep Flint from swallowing it

Burton is the rare Michigan city that turned itself into a city on purpose, defensively, the way you’d build a fence. For most of its life it was a farming township east and south of Flint. Then in the early 1970s Flint kept reaching across its borders, annexing township land a piece at a time, and Burton’s residents did the one thing that legally stops that: they incorporated as a city of their own in 1972. A city can’t be annexed by a neighbor. The fence held.

The roots run a lot deeper than the paperwork. Land was first bought here in 1829, but the community really took shape around 1835, when brothers Shubael and Perus Atherton and their nephew Pliny Skinner came over from Pontiac and settled along Thread Creek. For two decades the place was simply “the Atherton settlement.” Those first families helped cut the second road ever built in the county and survived a brutal winter in 1836 that killed several of them, including a young schoolteacher.

Today Burton is the second-largest city in Genesee County — nearly 30,000 people — a swath of neighborhoods, shops, and the For-Mar nature preserve wrapped around the southeast edge of Flint. It has no single downtown the way Fenton or Flushing does, which is a direct fingerprint of how it formed: not a village that grew outward, but a township that drew a hard line around itself.

Stand at Thread Creek today and it’s an ordinary suburban stream. Picture the Athertons clearing the second road in the county along it, and the place that incorporated to stay independent starts to make sense.
