Canals, mangroves and the beach
Marco Island, a city since August 27, 1997, is a barrier island in Southwest Florida's Ten Thousand Islands area, with six miles of beach and more than 100 miles of waterways within 24 square miles. The Mackle brothers and their Deltona Corporation developed modern Marco Island, which officially opened on January 31, 1965; the master plan called for 90 miles of navigable bulkheaded waterways.
Marco Island's code protects mangroves, and their trimming is regulated by the Florida Department of Environmental Protection under the state Mangrove Trimming and Preservation Act. On Marco Island's beachfront, building or changing structures seaward of the coastal construction setback line is unlawful unless the City grants a variance or permit, and the state's Coastal Construction Control Line program regulates structures that can cause beach erosion or destabilize dunes.
