MS4 Program and Plan Review Support

Ardurra partners with the City of Charleston to deliver MS4 plan review support services, helping the City meet NPDES permit obligations and enforce its Stormwater Design Standards Manual. The service streamlines review of over 500 annual construction activity applications, ensuring technical accuracy, regulatory compliance, and timely feedback to applicants. Ardurra leads all aspects of service delivery, including coordination with City staff, progress reporting, QA/QC oversight, and documentation. Each plan review is completed within 10 business days, supported by virtual kickoff meetings and detailed digital markups in Bluebeam Studio. A licensed South Carolina Professional Engineer performs independent quality assurance checks for every review. Innovative solutions include centralized FTP hosting for submittals, standardized review checklists aligned with SWDSM and CGP requirements, and integrated participation in the City's Technical Review Committee meetings. Deliverables include annotated plan sets, QA/QC documentation, monthly progress reports, and digital records for audit and compliance tracking.
