What is an ECL?
It is the erosion control line. An erosion control line is established in beach nourishment projects to identify the upland limits of state ownership as required by Florida State Statute. Since the state of Florida holds all lands below Mean High Water in public trust for all to use, the location of the ECL is based on the location of the mean (or average) high water elevation. In western Walton County, the Mean High Water elevation is +1.06ft.
