<br />GEOTECHNICAL <br />Substrata <br />The rock formations in South Florida are amongst the youngest in the country. This region of Florida is <br />divided into two topographic areas, the Atlantic Coastal Ridge and the Everglades. <br />In the City of Sunny Isles Beach, the surface consists of two to five feet of granular fill underlain by layers <br />of peat and/or organic silt to depths of about 10 to 15 feet below ground. Below this the Miami Limestone <br />Formation is generally encountered. The Fort Thompson Formation underlies the Miami Limestone and is <br />characterized by salt water limestone with localized freshwater limestone deposits. The formation is very <br />fossiliferous, highly porous and permeable, and contains coquina-like structures in certain areas. <br /> <br /> <br /> <br />Bridge Park Substrata Sketch <br />D-23
