24/7 Trauma and Biohazard Cleanup in Lloyd Harbor, NY

Lloyd Harbor is an incorporated village in the Town of Huntington in Suffolk County, on the North Shore of Long Island, and it was incorporated in 1926 when Lloyd Neck and West Neck joined as one municipality.

In 1654 the Matinecock Native Americans sold 3,000 acres of what is now Lloyd Neck to English settlers from Oyster Bay, and they called the region Caumsett, meaning "place by sharp rock."

James Lloyd acquired the neck in 1676, and the house built by his son Henry Lloyd still survives inside Caumsett State Historic Park.

During the Revolutionary War the British built fortifications on the neck, including Fort Franklin, and Joseph Lloyd was forced to abandon his manor house.

In 1886 Lloyd's Neck, once known as Queens Village, was separated from Queens County and annexed to the town of Huntington in Suffolk County.

In the early 1900s the area became part of Long Island's Gold Coast, as wealthy families such as Marshall Field III, William Matheson and George McKesson built seaside estates there.

Marshall Field III's great estate is now Caumsett State Historic Park Preserve, while another Gold Coast estate became a Roman Catholic seminary and Charles Robertson's estate became the Banbury Center of Cold Spring Harbor Laboratory.

In 1969 residents defeated a Long Island Lighting Company plan to build a nuclear power plant in the village, and Ferdinand Eberstadt instead donated his 80-acre estate to become the Target Rock National Wildlife Refuge.

Lloyd Harbor had a population of 3,571 at the 2020 census, living in 1,150 households, and BusinessWeek once ranked it among the wealthiest towns in America.

The village covers about 10.6 square miles, of which roughly 12 percent is water, and all of its public-school students attend the Cold Spring Harbor Central School District.
