Non-Compliance SCM Repair

Stormwater Management

Non-compliant stormwater control measure requiring inspection and maintenance in North Carolina

Non-compliant stormwater control measures (SCMs) can lead to failed inspections, regulatory violations, and increased flood risk. CMS restores stormwater BMPs—including detention basins, wet ponds, infiltration systems, and underground drainage structures—to meet state and municipal compliance standards. We correct sediment buildup, structural damage, erosion issues, and malfunctioning outlet devices that compromise system performance. Our stormwater rehabilitation services bring aging and failed SCMs back into compliance while protecting water quality and infrastructure integrity.

Expert Assistance for Non-Compliant SCM Violations

Overgrown or Non-Compliant Vegetation

Unmanaged vegetation can obstruct flow paths, damage structural components, and reduce the effectiveness of stormwater control measures. Invasive species often outcompete designed plantings, altering system performance. Proper vegetation management ensures SCMs function as engineered and remain inspection-ready.

Illicit Discharge / Illegal Connection

Illicit discharges—such as wash water, chemicals, oils, or unauthorized connections—introduce pollutants directly into the stormwater system. These violations threaten water quality, trigger regulatory enforcement, and can result in significant fines. Immediate identification and correction are critical to restoring stormwater compliance and protecting downstream waterways.

Sediment Accumulation

Excessive sediment buildup is one of the leading causes of stormwater SCM non-compliance. Accumulated soil and debris reduce storage capacity, restrict flow, and compromise BMP performance. Routine sediment removal restores hydraulic efficiency and prevents inspection failures.

Erosion at Inlets & Outlets

Severe erosion around stormwater inlets, outlets, and embankments undermines structural stability and disrupts proper drainage. Left unaddressed, erosion can cause slope failure, sediment discharge, and regulatory violations. Stabilization and repair protect both infrastructure integrity and water quality compliance.

SCM Maintenance & Inspection Failure

Failure to conduct required inspections and routine maintenance is a frequent cause of stormwater violations. Structural deficiencies, sediment accumulation, and clogged outlets often go unnoticed without regular oversight. Proactive inspection programs protect compliance and extend infrastructure lifespan.

Wet Pond & Detention Basin Failures

Wet ponds and detention basins commonly fail due to sediment overload, outlet malfunction, or embankment deterioration. Structural deficiencies reduce storage volume and impair peak flow control. Rehabilitation restores stormwater capacity, improves water quality treatment, and resolves compliance deficiencies.

Trash & Debris Clogging

Excessive trash and debris clog catch basins, orifices, and structural controls, restricting stormwater conveyance. Blockages increase flood risk and compromise BMP performance during heavy rainfall events. Routine debris removal protects drainage efficiency and prevents inspection violations.

Importance of Stormwater Management

Stormwater management is a critical part of protecting property, infrastructure, and natural resources by controlling runoff volume and reducing pollutants carried by rainwater. Engineered stormwater control measures (SCMs) such as wet ponds, bioretention basins, infiltration systems, and swales are designed to treat runoff, reduce erosion, and improve water quality before water enters streams, rivers, and lakes. Without effective stormwater management, uncontrolled runoff can cause flooding, property damage, and increased sedimentation in receiving waters, leading to non-point source pollution concerns. For commercial, industrial, and regulated sites across North Carolina, proactive stormwater management supports regulatory compliance and reduces long-term operational risks. CMS provides comprehensive stormwater solutions that help property owners plan, implement, and maintain stormwater systems to protect assets and meet performance expectations.

Maintenance of Stormwater SCMs

Routine maintenance of stormwater SCMs is essential for long-term performance, as sediment buildup, vegetation overgrowth, and clogged inlets can significantly diminish treatment capacity and hydraulic function. Regular maintenance ensures that SCMs, such as wet ponds, permeable pavements, and sand filters, continue to capture and treat stormwater runoff as designed. Without ongoing care, SCMs can fail to remove pollutants effectively, increasing the risk of flooding and environmental impacts downstream. CMS provides scheduled maintenance programs tailored to each SCM, helping clients avoid costly failures and ensuring reliable stormwater performance.

Repairs of Stormwater SCMs

Stormwater SCM repair services are critical when systems demonstrate structural issues, sediment reduction in storage capacity, or impaired hydraulic performance. Repairs may involve restructuring outlet controls, restoring eroded embankments, replacing damaged components, or rehabilitating clogged media in filtration systems. Timely SCM repairs prevent small issues from developing into system failures that compromise water quality and increase risk of flooding. CMS delivers stormwater system repair expertise that addresses both routine and non-routine corrections to restore SCMs to their original operating condition.

Inspections of Stormwater SCMs

Stormwater SCM inspections identify maintenance needs, structural concerns, and performance deficiencies that could reduce treatment effectiveness or lead to regulatory non-compliance. Quarterly, annual, and post-storm inspections help owners track sediment accumulation, vegetation conditions, and hydraulic function to ensure SCMs operate as intended. CMS utilizes certified stormwater inspectors and documented inspection protocols to provide thorough evaluations and detailed reporting. These professional inspections support stormwater compliance goals and help guide maintenance and repair planning for each SCM device.
