Stormwater Management
Post-Rain Inspections
NPDES Construction Generic Permit requirements call for site inspections after qualifying rainfall events in addition to routine periodic inspections. LES performs both, documenting BMP condition, identifying needed repairs, and maintaining the inspection record that supports your SWPPP compliance file.
What’s Included
- Post-rain-event inspections following qualifying storm events per permit requirements
- Routine periodic inspections on the schedule required by the SWPPP
- Written inspection reports documenting BMP condition and any deficiencies
- Corrective action tracking through to resolution
- Inspection recordkeeping organized to support audit and regulatory review
Technical Notes
Inspection documentation is frequently the first thing a regulatory inspector reviews on a site visit. A consistent, well-documented inspection history — with corrective actions tracked to completion — is one of the clearest signals that a site is being actively managed rather than just permitted.
Frequently Asked Questions
How often do construction sites need to be inspected?
NPDES CGP requirements generally call for both routine periodic inspections and inspections following qualifying rainfall events — the exact frequency and rainfall threshold are set by the active permit, and LES tracks both schedules for each site under retainer.
What happens if an inspection finds a deficiency?
Deficiencies are documented with a corrective action and tracked through to resolution and re-inspection — the goal is a closed-loop record, not just a list of problems.
