What drives Holley’s History grade
On its age, its old homes and the National Register, Holley is more historic than 97% of U.S. towns. All 3 inputs are above most U.S. towns; its share of homes from before 1940 ranks highest and its age lowest.
A+
HistoryA character grade: shown, never part of Holley’s overall grade.
New York towns list more on the Register than most of the country (a typical New York town has 12.3 per 10,000 residents, the U.S. 2.4), so Holley’s 218 sits above most of its state (83% of New York towns have fewer) while its 42 historic buildings outnumber those of 84% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from A to A+. The pre-1940 share is a Census survey estimate (±8.4 points). The founding year is the first post office, not a stated founding date.

The village of Holley was incorporated in 1850. Originally named Saltport, the name was changed to honor Myron Holley, a commissioner of the Erie Canal.
In 2002, a major chemical spill known as the Diaz pipeline incident occurred at the Diaz chemical production plant after a pipeline from a reactor vessel bursted, contaminating 31,000 tons of concrete and scrap metal as well as multiple houses, temporarily rendering Holley a ghost town.
