Great Kills Park is a public park in Great Kills, Staten Island, New York City. It is a part of the Staten Island unit of Gateway National Recreation Area. Administered by the National Park Service, it covers an area of approximately 580 acres (2.3 km2) of salt marsh, beach and woodlands, stretching along two miles (3 km) of Staten Island's south shore.
The park's main entrance is at Hylan Boulevard and Buffalo Street, where there is a bus stop for the S78, S79 SBS buses. The Bay Terrace station of the Staten Island Railway is also near the main entrance. Boaters can arrange access at Nichols Marina in Great Kills Harbor.
In 1860, the businessman and pioneering naturalist John J. Crooke bought a part of the land and lived in a wooden house at the beach. In 1916, severe erosion cut the narrow spit of land and Crooke's Point became an island to itself.
As early as 1925, the New York City government was considering buying 50 acres (20 ha) of Crooke's land to build a playground. Mayor John Francis Hylan considered purchasing up to 443 acres (179 ha) of land for a larger park, with provisions for future additions to bring the park's size to 1,000 acres (400 ha). A resort would be built on the site, which was expected to cost $10 million.
In 1929, the city bought Crooke's Point and adjacent land and started to build a public park. Due to the Great Depression and World War II, the work was delayed and the park could not be opened to the public until 1949. It became part of the Gateway National Recreation Area in 1973, along with Miller Field and Fort Wadsworth on Staten Island, Jamaica Bay in Brooklyn and Queens, and Sandy Hook in New Jersey.
Great Kills Harbor, located within the park, was created in the 1940s by expanding and reconnecting Crooke's Island to the rest of Staten Island, using landfill and dredge material. Numerous species of birds frequent the park's diverse habitats. The park now includes the Nichols Marina, a beach, trails, fishing and bird-watching areas, and sports fields.
The park's 15 million cubic yards of 1940s-era landfill included sanitary and medical waste. In 2005, radioactive radium (226Ra, once used in cancer treatments) was found in the sand at a depth of about 1–1.5 feet (30–40 cm). Directly at the sources, investigators measured gamma radiation about 200 times higher than the natural background level. Nearly half the park has been closed to the public since 2009, and the National Park Service expects to complete a comprehensive study in 2020 for its long-term decontamination project.
