how high above sea level is jacksonville fl
Jacksonville, Florida The state of Florida, including Jacksonville, is a huge flat plateau with a high water table, and surface lakes are very shallow.[48] The United States Geological Survey states that the highest point in Jacksonville is only 40 feet (12.2 meters) above sea level, making the area susceptible to flooding and storm surge.[49] Soil composition is primarily sand and clay rather than limestone, so very few sinkholes develop; however deep, large diameter sinkholes do occur.[50]
