The General Assembly finds and declares that structures located upon the public waters of the State which are used as places of temporary or permanent habitation, dwelling, sojournment, or residence interfere with the state’s proprietary interest or the public trust, or both, and must be removed to ensure the rights of the State and the people of South Carolina to use and enjoy the public waters of the State. It is declared to be the policy of this State and the intent of this chapter to protect the public waters of the State by authorizing the removal of nuisance structures from the public waters of the State in accordance with the procedures and within the timetable set forth in this chapter.
