Dunehampton is the name of a village that was proposed in 2003 to be incorporated along 5 miles (8.0 km) of Atlantic Ocean beach between Southampton (village), New York and Wainscott, New York.
The village would have included 200 houses, 1,730 acres (7.0 km2), taking in Julie and Channel Ponds at the western edge of Southampton Village and much of Sagg Pond to its eastern end at the border with East Hampton (town), New York.
The proposal met stiff resistance from the communities of Water Mill, New York, Bridgehampton, New York and Sagaponack, New York because they feared the village would impose strict parking rules on the beaches cutting them off from the ocean.
One of the most prominent residents along the narrow strip is Humvee tycoon Ira Rennert.
The petition to form the village was filed with the Southampton Town Supervisor Patrick A. Heaney on July 3, 2003. Residents of Sagaponack filed incorporation papers with the clerk on October 2, 2003. The two villages overlapped on the eastern portion of Dunehampton. Healy ultimately ruled that Dunehampton's application was not valid because it lacked the necessary number of signatures. Sagaponack's incorporation moved forward.
Subsequent court cases have upheld the decisions.
