Oyster Bay and Nassau County
Oyster Bay is associated with Nassau County in the Census boundary data. Start with the parcel’s tax bill to match the property to that jurisdiction, then confirm which government handles its land use.
Oyster Bay by land and water
The Census records 65.7 square miles of water within Oyster Bay, or 38.8% of its total area. It is 1.6 percentage points higher than the 37.2% recorded for Nassau County. This is geographic context; waterfront status and usable land must be checked at the parcel.
For scale, Oyster Bay town has 20.8 times the land area of nearby Syosset CDP (4.98 square miles). These areas describe boundaries, not comparable property prices.
