Key Biscayne is an island town in Miami-Dade County, Florida, United States. 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.
In recent years, the construction of several large resort hotels, condominium complexes and shopping centers on the island has affected the once bucolic island life, as commercialism has continued to accelerate at a frenetic pace. The Village has its own fire, police and public elementary and middle school. The millage tax rate remains one of the lowest of any municipality in Miami-Dade County. In 2004, the Village completed the construction of a civic center including fire, police and administration buildings and a recreation and community center with indoor multi use courts, outdoor swimming pool and a renowned musical theater program.
The median income for a household in the village was $86,599, and the median income for a family was $107,610. Males had a median income of $86,322 versus $46,765 for females. The per capita income for the village was $54,213.
Miami-Dade County Public Schools serves Key Biscayne. The Key Biscayne K-8 Center serves Key Biscayne. Middle school students may attend Ponce de Leon Middle School in Coral Gables instead of the Key Biscayne School. High school students are zoned to Coral Gables High School. In 2012 MAST Academy, a magnet school on Virginia Key, announced it will expand by 1,100 seats with preference for eligible Key Biscayne residents. The Miami-Dade Public Library System operates the 6,000-square-foot Key Biscayne Branch Library. It opened in January 1985.
