About Sanibel
Sanibel is a city in Lee County, Florida, United States, on Sanibel Island. The population was 6,469 at the 2010 census, with an estimated 2012 population of 6,741. It is part of the Cape Coral-Fort Myers, Florida Metropolitan Statistical Area.
Sanibel is a barrier island – a collection of sand on the leeward side of the more solid coral-rock of Pine Island.The city incorporates the entire island, with most of the city proper at the east end of the island. After the Sanibel causeway was built to replace the ferry in May 1963, the residents asserted control over development by establishing the Sanibel Comprehensive Land Use Plan in 1974 helping to maintain a balance between development and preservation of the island’s ecology.[4] A new, higher bridge, permitting passage without a bascule bridge (drawbridge) of tall boats and sailboats, was completed in late 2007.
