Coney Island. Coney Island is a residential and commercial neighborhood and entertainment area, located on a peninsula in the southwestern part of the borough of Brooklyn in New York City. The neighborhood is bounded by Manhattan Beach to its east, Lower New York Bay to the south and west, and Gravesend to the north, and includes the subsections of Sea Gate to its west and Brighton Beach to its east. Coney Island was formerly the westernmost of the Outer Barrier islands on the southern shore of Long Island, but in the early 20th century it became a peninsula, connected to the rest of Long Island by land fill. The origin of Coney Island's name is disputed, but the area was originally part of the colonial town of Gravesend. By the mid-19th century it had become a seaside resort, and by the late 19th century, amusement parks had also been built at the location. The attractions reached a historical peak during the first half of the 20th century. However, they declined in popularity after World War II, and following years of neglect, several structures were torn down. Various redevelopment projects were proposed for Coney Island in the 1970s through the 2000s, though most of these were not carried out. The area was revitalized with the opening of MCU Park in 2001 and several amusement rides in the 2010s. Coney Island has 31,965 residents as of the 2010 United States Census. The neighborhood is ethnically diverse, and the neighborhood's poverty rate of 27% is slightly higher than that of the city as a whole. Coney Island is part of Brooklyn Community District 13 and its primary ZIP Code is 11224. It is patrolled by the 60th Precinct of the New York City Police Department. Fire services are provided by the New York City Fire Department's Engine 245/Ladder 161/Battalion 43 and Engine 318/Ladder 166. Politically, Coney Island is represented by the New York City Council's 47th District. The area is well served by the New York City Subway and local bus routes, and contains several public elementary and middle schools. The Coney Island neighborhood is generally coextensive with the peninsula of the same name, located on the western end of Long Island lying to the west of the Outer Barrier islands along Long Island's southern shore. The peninsula is about 4 miles long and 0.5 miles wide. It extends into Lower New York Bay with Sheepshead Bay to its northeast, Gravesend Bay and Coney Island Creek to its northwest, and the main part of Brooklyn to its north. At its highest it is 7 feet above sea level. Coney Island was formerly an actual island, separated from greater Brooklyn by Coney Island Creek, and was the westernmost of the Outer Barrier islands. A large section of the creek was filled in the 1920s and 1930s, turning the island into a peninsula. A narrower definition of the Coney Island neighborhood is given by the Encyclopedia of New York City, which only considers the area west of Ocean Parkway to be part of that neighborhood. The perimeter of Coney Island features manmade structures designed to maintain its current shape. The beaches are currently not a natural feature; the sand that is naturally supposed to replenish Coney Island is cut off by the jetty at Breezy Point, Queens. Sand has been redeposited on the beaches via beach nourishment since the construction of Riegelmann Boardwalk in 1922-1923, and is held in place by around two dozen groynes. A large sand-replenishing project along Coney Island and Brighton Beach took place in the 1990s. Sheepshead Bay at the peninsula's northeast corner is, for the most part, enclosed in bulkheads. Two major parks, Kaiser Park and Coney Island Creek Park, are located on the northwest side of the peninsula along Coney Island Creek. The original Native American inhabitants of the region, the Lenape, called this area Narrioch. This name has been attributed the meaning of land without shadows or always in light describing how its south facing beaches always remained in sunlight. A second meaning attributed to Narrioch is point or corner of land. There is no clear historical consensus on how the island got the name Coney Island. A version of this name, Conyne Eylandt, shows up in early 17th century Dutch maps.
