Back to Permitting and Regulation
Excavation in South Florida is done to extract fossilized shell to make concrete, acquire fill for construction and to store water. If lakes and mines are dug too deep with poorly sloped edges, they can be hazardous to people and result in poor water quality, harming the surrounding environment. Since 1992, ERM has regulated excavation and mining through the Palm Beach County Unified Land Development Code (ULDC) Article 4.D, Excavation.
ERM has increased health and safety, prevented erosion and loss of property, increased water quality and provided habitat by regulating excavation.
Lakes regulated by ERM larger than 1 acre OR deeper than 6 feet must have a planted littoral area with 5 different species of native aquatic plants covering at least 80% and no more than 10% exotic plants.
Why are they good?
Native aquatic plants growing in the littoral zone
reduce erosion by stabilizing the banks, increase water quality by taking up nutrients settled in the sediment, and
provide habitat for wading birds and other wildlife. If you have littoral plants that recruit (fill in), then you have a
