Stormwater Wetlands

Stormwater Management

Constructed stormwater wetland using native vegetation to remove pollutants and improve water quality in North Carolina

Stormwater Wetland Maintenance Services

CMS provides stormwater wetland maintenance services for commercial developments, municipalities, and HOAs throughout North Carolina. Stormwater wetlands require consistent maintenance to preserve plant communities and maintain water quality treatment performance. Sediment accumulation, invasive vegetation, and blocked flow channels can quickly reduce system effectiveness. CMS crews maintain wetland cells, forebays, and outlet structures to ensure proper treatment flow. Our services help property owners maintain stormwater permit compliance and long-term SCM performance.

Stormwater Wetlands Maintenance Services

CMS maintenance programs focus on preserving healthy vegetation and maintaining hydraulic flow between wetland cells. Preventive maintenance reduces sediment buildup and prevents invasive plant growth. Routine service helps wetlands continue removing nutrients and pollutants from stormwater runoff.

Typical CMS Wetland Maintenance Services

Removal of invasive vegetation
Sediment removal from forebays
Flow channel maintenance between wetland cells
Debris removal from inlet structures
Vegetation management and replanting
Outlet structure maintenance and cleaning

Stormwater Wetlands Inspection Services

CMS performs stormwater wetland inspections to monitor vegetation health, sediment levels, and water flow. Our inspection teams verify hydraulic connectivity between wetland treatment zones. Detailed inspection reports identify maintenance and repair needs early.

Stormwater Wetlands Repair Services

CMS repair crews restore stormwater wetland performance through sediment removal, berm repair, and vegetation restoration. Structural repairs may include outlet control adjustments or erosion stabilization. Timely repairs protect both water quality treatment and regulatory compliance.

Stormwater Wetlands FAQs

Above Ground SCM Maintenance, Repairs, and Inspections

Stormwater Maintenance – Aboveground SCM Devices

Routine maintenance of aboveground stormwater control measures (SCMs) such as bioretention areas, detention ponds, sand filters, and vegetated swales ensures these systems function as originally designed. Services include debris removal, sediment cleanout, vegetation management, erosion repair, and outlet structure cleaning to maintain proper flow and treatment capacity. CMS provides proactive maintenance programs that protect water quality, prevent system failures, and keep facilities operating efficiently year-round.

Compliance, Longevity & Sustainability:
Consistent maintenance helps property owners remain compliant with state and local stormwater permits by ensuring SCMs meet performance standards. Removing sediment buildup and correcting minor issues early extends the service life of infrastructure and prevents costly rehabilitation. Properly maintained systems improve pollutant removal, reduce downstream impacts, and support long-term environmental sustainability goals.

Stormwater Repairs – Aboveground SCM Devices

Stormwater repair services address structural damage, erosion, failing outlet structures, compromised embankments, and deteriorated components within aboveground SCMs. Timely repairs restore hydraulic performance and prevent minor deficiencies from escalating into major failures. CMS evaluates system conditions and implements targeted repair solutions to return SCMs to full operational capacity.

Compliance, Longevity & Sustainability:
Prompt repairs help maintain regulatory compliance by correcting deficiencies often cited during inspections. Restoring structural integrity protects the long-term durability of the asset and reduces the risk of emergency replacements. Sustainable repair practices preserve existing infrastructure, reduce waste, and ensure continued water quality treatment performance.

Stormwater Inspection – Aboveground SCM Devices

Professional inspection of aboveground SCMs includes detailed visual assessments, sediment measurements, structural evaluations, and documentation of overall system performance. Regular inspections identify developing issues such as clogging, erosion, vegetation overgrowth, or structural deterioration before they compromise function. CMS provides thorough inspection reporting to support maintenance planning and regulatory documentation requirements.

Compliance, Longevity & Sustainability:
Routine inspections are critical for meeting permit requirements and demonstrating due diligence to regulatory agencies. Early detection of deficiencies reduces long-term repair costs and maximizes the lifespan of stormwater assets. By ensuring systems operate efficiently, inspections contribute to sustainable watershed protection and responsible environmental stewardship.
