What drives Utica Township’s History grade
On its age, its old homes and the National Register, Utica Township is more historic than 86% of U.S. towns. All 3 inputs are above most U.S. towns; its age ranks highest and its National Register listings lowest.
A
HistoryA character grade: shown, never part of Utica Township’s overall grade.
Few Illinois towns list much on the Register (a typical Illinois town has 0.5 per 10,000 residents, the U.S. 2.4), so Utica Township’s 10.6 sits above most of its state (84% of Illinois towns have fewer) while its 2 listings outnumber those of 60% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would still be A−. The pre-1940 share is a Census survey estimate (±5.4 points). The founding year is the first post office, not a stated founding date.

Timeline
Utica Township, 1892 to 1933
Woven from the archive, old maps, post office records, the National Register and the people born here.
The town of Utica had previously been established on the banks of the Illinois River near the Indian village Kaskaskia during the 1830s, but flooding and the construction of the Illinois and Michigan Canal a few miles north encouraged redevelopment of the village there as North Utica.
An F3 tornado struck Utica on April 20, 2004, heavily damaging the downtown business district, causing $8 million in damage and killing 8, with another indirect fatality officially recognized by the village.
A 2022 Memorial Day fire damaged twenty eight privately owned cabins near the entrance to Starved Rock State Park likely because of a grill fire. The Grand Bear lodge, waterpark and a majority of the cabins and villas on site were not affected.
The Utica Township post office opened in 1834, the earliest record of the town by name (U.S. post office records).
