Environmental Services Tool Shed

The SCDOT Environmental Services Tool Shed is our repository for documents, forms, templates, references, and guidelines about transportation and the environment and federal, state and agency environmental requirements. Practitioners can use these tools to assist local governments, consultants, and SCDOT staff in integrating environmental considerations into the environmental process to achieve regulatory compliance for SCDOT projects. We welcome feedback to improve our Tool Shed.

Aims to reduce the number of projects at risk due to the lack of wetland and stream mitigation bank credit coverage and the number of projects at risk due to low wetland and stream credit availability. Users can view the estimated stream and wetland impacts for SCDOT projects within each watershed as well as see the estimated impacts per year.
