“The island of Chicken Key, located approximately one mile offshore, was formed by the deposition of quartz and limestone sands by ocean currents. An 1899 survey by S. H. Richmond recorded a maximum elevation of three feet above sea level and historically, the island was characterized by a sand beach and low dunes. Dredge deposits in the 1940s increased elevations from 3 to 10 feet on most of the island, destroying the dunes. In 1996-1997, the County restored Chicken Key, removing dredged materials, connecting the mangrove forest and dune system, and re-creating the island’s original topography.” Deering Estate Natural Resources
