Islandia is an unincorporated community and former city in Miami-Dade County, Florida, United States. It is located in the upper Florida Keys on the islands of Elliott Key and other nearby keys, such as Totten Key. It was the only municipality in the Florida Keys not located in neighboring Monroe County. The population was 18 at the 2010 Census. Most residents of the city were National Park Service employees. In the 2010 Primary Election, the Miami-Dade County Commission was empowered via a charter amendment to abolish Islandia. On December 6, 2011, Miami-Dade County Commissioners unanimously approved an ordinance to abolish the city, with final action to be taken after a public hearing. Following a public hearing, the ordinance abolishing Islandia received final approval on March 6, 2012, and took effect on March 16, 2012. History Islandia, and in particular Elliott Key, was originally fished by the Native American Tequesta people. It subsequently became a haven for shipwreck survivors. By the mid-1800s, a group of Bahamians had made their way to the key, where they unsuccessfully tried farming on an island with a base of coral rock. By the early 1900s, Islandia had its own school district and more than 100 residents. However, the number of residents dwindled over time due to the lack of electricity, poor farming, and the relatively long distance from the mainland. In 1950 the Dade County Planning Board announced a plan to build a highway connecting Key Biscayne with the Overseas Highway on Key Largo. The project envisioned a series of bridges connecting artificial islands, to be built on the Safety Valve, and existing small keys to Elliott Key and on to Key Largo. When the Dade County Planning Board was unable to secure a right of way for the highway across the southern end of Key Biscayne, it dropped the plan. At the end of 1960, however, 13 of the island's 18 registered voters approved the incorporation of a municipality, and the 33 northernmost islands of the Florida Keys became the city of Islandia. Developers and the residents revived the plan to build a causeway across the bay, and sought to fill Elliott Key with luxury hotels, golf courses, oceanfront homes, and a six-lane roadway running down the center of the key. A grassroots opposition of fishermen, gardeners, and elected state leaders opposed the plan, and sought to include the islands in the national park
