Overview
Private Island with Sandy Beaches
This 145.5-acre private island, known as MAIN KEY, features over a mile of pristine white sandy beaches along its eastern shoreline in Barnes Sound, Monroe County, FL. The island also includes over 4 miles of mangrove shoreline, reaching heights of 30 to 50 feet, which serves as a rookery teeming with gamefish, shellfish, sea mammals, and tropical birds. The property is conveyed via a TIFF Deed. With 12 upland acres, a substantial structure could be built without ROGO requirements. Historical records indicate that in the 1930s and 40s, there were 3 large structures on the SE Government Lot area. A new dock permit exists for the SE beach off the old homesite, including a lift, platform, and mooring slip. An additional permit is being applied for on the south side of Main Key for a 135 ft dock with a 40 ft platform and seven heavy pilings, designed to moor a large vessel of up to 100 ft in length. A tide station was established by the USGS, later NOAA, in the 1930s. 'The Tides at Main Key' was a well-known reference point in Marine Weather forecasts on South Florida TV and NOAA Weather Radio for the Upper Keys and Florida Bay. The property is located in the OS - Offshore Island District.
