What drives East Rockaway’s History grade
On its age, its old homes and the National Register, East Rockaway is more historic than 66% of U.S. towns, #558 of 758 in New York. Its share of homes from before 1940 holds the grade up; its age pulls it down.

HistoryA character grade: shown, never part of East Rockaway’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 East Rockaway’s 3.0 sits below most of its state (29% of New York towns have fewer) while its 3 historic buildings outnumber those of 65% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C to A−. The pre-1940 share is a Census survey estimate (±8.0 points). The founding year is the first post office, not a stated founding date.

Originally named Near Rockaway, the village began as a shipping and trading center for the South Shore of Long Island. The village's location was desirable for ships because of its deep channels inland. Eventually a grist mill was built on the Mill River by Joseph Haviland through a land grant in 1688. The Haviland-Davison Grist Mill, located in Memorial Park, was listed on the National Register of Historic Places in 1998. Later, an oven was purchased to make bread for the surrounding population. The village prospered in shipping and milling over the years, even after several sales of the land.
The village was incorporated in 1900, and Floyd Johnson was its Village President.
At the time of incorporation the village had a population of 969.

The East Rockaway post office opened in 1870, the earliest record of the town by name (U.S. post office records).
