History grade
What drives Grass Lake Township’s History grade
On its age, its old homes and the National Register, Grass Lake Township is more historic than 82% of U.S. towns, #121 of 701 in Michigan. All 3 inputs are above most U.S. towns; its age ranks highest and its share of homes from before 1940 lowest.
A−
HistoryA character grade: shown, never part of Grass Lake Township’s overall grade.
Few Michigan towns list much on the Register (a typical Michigan town has 0.0 per 10,000 residents, the U.S. 2.4), so Grass Lake Township’s 6.5 sits above most of its state (78% of Michigan towns have fewer) while its 4 historic buildings outnumber those of 68% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from B+ to A−. The pre-1940 share is a Census survey estimate (±4.7 points). The founding year is the first post office, not a stated founding date; Wikidata’s 1842 falls in the same era, so the grade doesn’t depend on which one is used.

What stands out about Grass Lake Township’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
In 1842, the Michigan Central Railroad bypassed the original village and built a depot 1.5 miles (2.4 km) to the west when an offer of $1.50 an acre was offered (compared to $2.00 an acre at the previous city center) [1]. The village was relocated to this new location - its current location - to be closer to the rail depot and some of the original buildings were relocated to the new site.
In 1887, Grass Lake was awarded a stone depot designed by the same architects, Spier and Rohns, and with stone from the same quarry as the Ann Arbor station. The historic Romanesque Whistle Stop Depot offers displays of local interest and is available for rental.
