Stormwater Maintenance Inspections
Last updated: April 2025
Why Regular Inspections Matter
Stormwater infrastructure fails quietly. Sediment builds up, pipes crack, and outlets erode long before anyone notices. Regular inspections catch these problems early, before they cause flooding, compliance notices, or expensive emergency repairs.
Key Inspection Components
Collection Systems and Inlets
- Inlets and curb cuts must be inspected for debris accumulation and structural integrity.
- Proper drainage flow should be verified to prevent localized flooding.
Piping and Inflow Structures
- Inspect stormwater piping for cracks, blockages, or sediment buildup.
- Evaluate Flared End Sections (FES) and Mitered End Sections (MES) for erosion control and proper discharge.
Detention and Retention Basins
- Check for excessive sediment buildup and proper outlet functionality.
- Ensure vegetation management is maintained for optimal water quality and flow regulation.
Filtration and Infiltration Systems
- Assess sand filters, bio-retention areas, and infiltration systems for clogging and proper drainage.
- Verify that filtration media are functioning as designed to remove pollutants.
Underground Detention Systems (UDS)
- Inspect for structural integrity, sediment accumulation, and proper outflow.
- Ensure maintenance access points are clear and functional.
Documentation and Compliance
Documenting inspections with photos is crucial for tracking asset conditions over time and demonstrating compliance with local and state regulations. Clear records of inlet structures, piping conditions, sediment accumulation, and filtration system performance help streamline maintenance planning and regulatory reporting.

FAQ
How often do I need a stormwater inspection in Charlotte?
Charlotte-Mecklenburg Post-Construction Stormwater Ordinance typically requires annual inspections for SCMs/BMPs. Some development agreements require quarterly or semi-annual checks. If you’ve received an NMR, an inspection report is usually the first step to closing it out.
What does a stormwater inspection report include?
Reports cover each SCM or BMP on site: current condition, photos, identified deficiencies, and maintenance recommendations. We format reports to meet Charlotte, Mecklenburg County, and surrounding municipality requirements.
What happens if my stormwater system fails inspection?
You’ll receive a deficiency list with prioritized corrective actions. We can handle minor maintenance on the same visit. Larger repairs, like basin dredging or pipe fixes, get scoped and scheduled separately. Having a documented response plan helps if Charlotte-Mecklenburg follows up.
Can I use the inspection report to respond to a Notice of Maintenance Required (NMR)?
Yes. An inspection report that documents current conditions and a corrective action plan is typically what the city needs to see. We’ve helped property owners close out NMRs with proper inspection documentation.
Do you inspect underground detention systems?
Yes. We inspect underground systems, vaults, and proprietary devices. Confined-space entry is coordinated separately when required for deep vault access.
