DERM stormwater compliance in Miami-Dade County
Miami-Dade's DERM enforces some of the strictest stormwater rules in Florida under Chapter 24. We handle the field maintenance: catch basin vacuuming, exfiltration trench recovery, hydro-jetting, and outfall screening. We also deliver the DERM-ready documentation package that closes out a notice or supports an inspection.
What DERM inspects
- Catch basin sediment depth against the cleaning trigger
- Exfiltration trench and French drain percolation (Miami-Dade uses these heavily due to the water table)
- Baffle boxes, treatment units, and pretreatment structures
- Outfalls to canals, secondary canals, or the C&SF system
- Illicit discharge indicators: sheen, staining, odor
- Current O&M documentation on file
Exfiltration trench recovery
Miami-Dade properties often rely on exfiltration trenches and French drains rather than surface ponds. When these clog with sediment, the entire site loses its retention capacity. The fix is targeted cleanout, not a bigger basin. We inspect, jet, vacuum, and re-verify percolation.
Responding to a DERM notice
DERM notices are workable when addressed promptly with documentation. We turn around a free aerial + permit desktop review in a few days, mobilize a crew for corrective work on your timeline, and hand you photos, manifests, and a signed report formatted for DERM submission.
