Non-Compliance SCM Repair
Stormwater Management
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.
Stormwater Compliance & Enforcement Actions
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.
Stormwater Systems We Maintain
Catch Basins, Inlets, Frames & Grates
Stormwater maintenance of catch basins, inlets, frames, and grates removes sediment and debris, restores hydraulic flow, prevents blockages, and ensures regulatory compliance.
Detention Ponds
Regular stormwater maintenance of detention ponds removes accumulated sediment, cleans outlet structures, and preserves storage capacity and peak flow control for effective flood management.
Retention Ponds
Stormwater maintenance of retention ponds maintains permanent pool conditions, clears debris, supports pollutant settling, and ensures long-term water quality performance.
Grassed & Rip Rap Swales
Stormwater maintenance of grassed and riprap swales stabilizes erosion, removes sediment, and preserves vegetation to protect hydraulic flow and site compliance.
Hydrodynamic Separators
Routine maintenance of hydrodynamic separators removes sediment, trash, and hydrocarbons to restore pollutant removal efficiency and optimal system performance.
Level Spreaders
Stormwater maintenance of level spreaders ensures even runoff distribution, prevents channelized flow, and protects downstream soils and vegetation.
Outfalls
Stormwater maintenance of outfalls removes debris, repairs structural issues, and stabilizes discharge points to prevent scour and maintain regulatory compliance.
Proprietary Stormwater Systems
Maintenance of proprietary stormwater systems restores filtration media, clears blockages, and preserves hydraulic performance and permit compliance.
Storm Sewer Systems
Stormwater maintenance of storm sewer systems clears pipes, removes sediment, and repairs joints to restore proper drainage and hydraulic efficiency.
Stormwater Infiltration Assets
Regular stormwater maintenance of infiltration assets improves soil permeability, restores runoff percolation, and ensures groundwater recharge and compliance.
Stormwater Vaults
Stormwater maintenance of underground vaults removes sediment, repairs structural components, and restores storage and treatment capacity for efficient system operation.
Debris Collection Devices
Routine maintenance of debris collection devices removes trash and floatables, protects downstream stormwater infrastructure, and ensures system efficiency.
Underground Stormwater Assets
Stormwater maintenance of underground assets—including pipes, chambers, and vaults—restores hydraulic performance, structural integrity, and compliance.
Above Ground Stormwater Assets
Stormwater maintenance of above ground assets stabilizes erosion, removes debris, and ensures accessible and compliant system operation.
Permeable Pavement
Routine stormwater maintenance of permeable pavement removes surface clogging, restores infiltration capacity, and maintains stormwater treatment efficiency.
Sand Filters
Stormwater maintenance of sand filters replaces clogged media, removes accumulated sediment, and restores filtration efficiency for pollutant removal and regulatory compliance.
Routine/Quarterly Inspections
Routine quarterly inspections of stormwater control measures identify sediment accumulation, debris, erosion, and vegetation issues before they impact system performance. These inspections help maintain compliance, extend SCM life, and ensure effective stormwater management year-round.
Post-Storm Inspections
Post-storm inspections are conducted after significant rainfall events to assess SCM functionality, identify immediate damage, and address any safety or operational concerns. Prompt evaluation after storms prevents flooding, erosion, and costly downstream repairs.
Annual Certified Inspections
Annual certified inspections verify that stormwater control measures are operating according to local regulations and design specifications. These formal inspections provide official documentation for compliance and ensure long-term system performance.
As-Built/Final Inspections
As-built inspections confirm that newly constructed stormwater control measures match approved plans and design requirements. Final inspections ensure proper installation, identify potential construction issues, and validate long-term functionality.
Remedial/Repair Inspections
Remedial inspections assess SCMs after notices of violation, damage, or structural failure to determine required repairs. These inspections guide corrective actions that restore system performance and maintain regulatory compliance.
Key Types of SCM Inspections
Comprehensive stormwater control measure (SCM) inspections are essential to maintain proper function, ensure NCDEQ compliance, and protect water quality across commercial and regulated sites. Routine quarterly, post-storm, annual certified, as-built, and remedial inspections identify sediment buildup, debris, erosion, vegetation issues, and structural concerns before they cause flooding or system failures. By performing these targeted SCM inspections, CMS helps extend the life of stormwater infrastructure, prevent costly repairs, and optimize overall stormwater management performance.
