BMP inspections for construction sites in Columbia, SC

Columbia and the Midlands generate more active land-disturbing permits than any region in South Carolina outside the coastal market. Commercial development along the Broad River Road corridor, large residential subdivisions pushing into Lexington County, mixed-use projects near the USC campus, and infrastructure work tied to the Fort Jackson area all require NPDES permit coverage and regular BMP inspection documentation under the SCDHEC Construction General Permit.

SC Drone Services covers active construction sites across Richland and Lexington counties with weekly and bi-weekly BMP inspection flights. A single flight documents the full site: every silt fence section, sediment basin, inlet protection device, stabilized construction entrance, slope stabilization measure, and any area of active erosion. GPS-tagged photos organized by BMP type, delivered within 48 hours.

Any construction activity disturbing one acre or more requires coverage under the SCDHEC Construction General Permit. The inspection schedule is fixed: at least once every seven calendar days during active land disturbance, and within 24 hours of a 0.5-inch rainfall event. Both clocks run independently. The inspection record must include the date, weather conditions at the time of inspection, findings at every BMP location, and any corrective action taken or required. Records stay in the SWPPP for at least three years.

SCDHEC inspects construction sites in the Columbia area and checks that inspection records are current, complete, and match site conditions. A missing or incomplete inspection record is a violation regardless of BMP condition on the ground.

Columbia's summer weather pattern produces frequent afternoon and evening thunderstorms that regularly trigger the 24-hour rain event inspection requirement across multiple sites simultaneously. A drone can be on a Richland County site at first light the morning after a rain event in the time it takes to complete a partial ground walk of the same site. Same-day rain event flights are available across the greater Columbia area for contracted clients.
