Key Biscayne is an island town in Miami-Dade County, Florida, United States. The population was 12,344 at the 2010 census.Key Biscayne lies south of Miami Beach and east of Miami. The village is connected to Miami via the Rickenbacker Causeway, originally built in 1947. Because of its low elevation and direct exposure to the Atlantic Ocean, it is usually among the first Miami areas to be evacuated before an oncoming hurricane.GeographyAccording to the United States Census Bureau, the village has a total area of 1.4sqmi. 1.3sqmi of it is land and 0.1sqmi of it (8.63%) is water.The village is bordered on the north by Crandon Park, Miami-Dade County park, on the south by Bill Baggs Cape Florida State Park, on the east by the Atlantic Ocean and on the west by Biscayne Bay.HistoryWhile there had been earlier schemes to develop a town on Key Biscayne, it wasn't until the opening of the four-mile long Rickenbacker Causeway from Miami to Virginia Key and on to Key Biscayne in 1947 that the island was opened up to large scale residential development. The northern two-thirds of the island had been operated as the largest coconut plantation in the continental United States during the first half of the 20th century. In 1940 the Matheson family donated over 800acre of their land to Dade County for a public park in exchange for a commitment that the county would build a causeway to the island. The remaining Matheson property, stretching across the middle of the island, was then sold off to developers. Starting in 1951, the Mackle Construction Company offered new homes on the island for US$9,540, with just US$500 down. A U.S. Post Office contract branch was opened, the Community Church started holding services in an old coconut-husking shed, and the Key Biscayne Elementary School opened in 1952.Key Biscayne is in Florida (FL).
