The bill H. 5742 proposes an amendment to the South Carolina Code of Laws by adding a new section, 4-9-125. This section allows a county council to enact an ordinance that prohibits annexation within the county by municipalities or any other political subdivisions of the state until a comprehensive infrastructure impact study and mitigation plan has been completed and approved by the county council.

This legislative change aims to ensure that any annexation efforts are preceded by thorough assessments of their potential impact on local infrastructure, thereby allowing county councils to maintain control over development and growth within their jurisdictions. The bill will take effect upon approval by the Governor.
