As part of the Town of Mount Pleasant’s Stormwater Management Plan, the Town requires construction project owners to plan and operate their projects with the goal of reducing the runoff and pollution generated by their construction activities.
** Please note that at this time all construction permitting questions related to the State Construction Permitting should be sent to SCDHEC Coastal Office at 843-953-0200.
The Town's technical review requires that project submittals meet the requirements of the most current Federal and/ or SCDHEC requirements, which may be more stringent than the Town's ordinance referenced below. The Town's ordinance will apply only if the specific water quality or quantity requirement is more stringent than the State requirement or to requirements specific to Town programs and other ordinances, such as developer and engineer responsibilities, submittals, inspections, warranties, and other such items contained in the Town's Codes.
The Town program includes measures for a regulatory control program to ensure all construction projects are in compliance with Town of Mount Pleasant Ordinance Chapter 153. This ordinance requires:
Water Quality Review ProcessTown review for your project is dependent on the land disturbance area and type of construction being completed. Use the NPDES Phase II Approval Process PDF to determine what type of Town review is appropriate for your project.
The Town charges NPDES Plan Review Fees and Water Quality Inspection fees for new projects. Please review our NPDES Fee Schedule and include a copy and the appropriate fees with your submittal. The plan review fee will not be charged by SCDHEC, unless they choose to perform a separate technical review. These fees are separate from the SCDHEC Permit Fee.
To find out more information on technical review submittal requirements for large construction projects in the Town, please visit the Planning Department.
Forms for Water Quality review submittals and the construction process can be found here.
A technical review by the state may also be required for your project. Use the State Permitting Requirements PDF to determine if you need to submit for a Construction General Permit (CGP) and Coastal Zone Consistency (CZC) review with SCDHEC-OCRM. Every project is unique so please contact the SCDHEC-OCRM office if you are unsure if your project must submit for review.

To view any new projects or submit comments, please view our "Construction Public Notice" page.

Implementation of Best Management Practices (BMPs)
Studies have found that runoff from construction activity can introduce a significant amount of pollution into the storm drain system, including sediment, debris and trash, pesticides, excess nutrients, sanitary waste, and oil and grease, among others. By employing a series of best management practices (BMPs) at your construction site, you can help protect water quality in our community.

Post-Construction Process and Long-Term Maintenance of BMPs

Please visit our "Post-Construction Process" page to find out more information on the long-term maintenance process and how it should be incorporated into your project.
