Biohazard Cleanup Near North Key Biscayne Key Biscayne, FL

Key Biscayne is a village on the barrier island of the same name in Miami-Dade County, between the Atlantic Ocean and Biscayne Bay, and it is the southernmost barrier island on the U.S. Atlantic coast.

The Village of Key Biscayne was incorporated on June 18, 1991, making it the first new municipality created in Miami-Dade County in decades.

Key Biscayne had a population of 14,809 at the 2020 census, up from 12,344 in 2010.

Key Biscayne was inhabited by the Tequesta people for centuries, and Juan Ponce de León named the island's southern tip Cape Florida in 1513.

The Cape Florida Lighthouse at the island's southern tip was first built in 1825 and is the oldest standing structure in Miami-Dade County.

The Cape Florida Lighthouse was attacked and set on fire on July 23, 1836, during the Second Seminole War — the keeper survived the attack, but his assistant was killed — and the rebuilt tower was raised to 95 feet in 1855 and formally relit after restoration in 1996.

Key Biscayne is connected to mainland Miami only by the Rickenbacker Causeway, a roughly 4-mile causeway opened in 1947 that first opened the island to large-scale residential development.

The northern two-thirds of Key Biscayne were operated as the largest coconut plantation in the continental United States during the first half of the 20th century, and in 1940 the Matheson family donated over 800 acres of it to the county, which became Crandon Park.

The village is sandwiched between two large parks — Crandon Park to the north and Bill Baggs Cape Florida State Park, which opened on January 1, 1967, to the south.

Key Biscayne was home to President Richard Nixon's 'Winter White House,' his Florida compound on Bay Lane that he used during his presidency.
