Commercial storm drain services in Miami-Dade County

Miami-Dade's stormwater program is the most layered in our service area. Every commercial property sits inside both a city MS4 (or the unincorporated-county MS4) and the overarching Miami-Dade Department of Regulatory and Economic Resources (RER, formerly DERM) stormwater program, which flows strict pollutant-discharge, BMP, and inspection-record obligations to commercial owners. New construction and any modern detention system sits under an SFWMD or county-issued ERP on top of that.

Geographically the county splits into four operating environments. The barrier islands and Bay frontage — Miami Beach, Sunny Isles, Bal Harbour, Key Biscayne, the Brickell waterfront — are tidally influenced, dependent on tide flaps and (in Miami Beach) on the City's raised-road and stormwater-pump program. King tides in October–November are when failures show up. The dense urban core — Brickell, downtown, Wynwood, Edgewater — has older infrastructure, tight access windows, and event-driven scheduling constraints. The industrial / logistics corridor — Doral, Hialeah, Medley, the Airport West area — generates heavy sediment, hydrocarbon, and metals loading, with many facilities operating under an NPDES Multi-Sector General Permit (MSGP). The historic and residential interior — Coral Gables, Pinecrest, Coconut Grove, South Miami — has mature canopy that loads inlets with leaf and seed debris year-round.

Florida's June 28, 2025 update to Chapter 62-330 changed who can certify the recurring O&M inspection: a qualified inspector can now sign the state form, while the periodic drainage-district or PE-required recertification still needs a licensed engineer's seal. We confirm what your specific permit, MS4, and (where applicable) MSGP require before quoting, and we hold both capabilities in-house.

The failure patterns we see most often in Miami-Dade are: stuck tide flaps on Bay-front and barrier-island properties (the cause of most "sunny-day" flooding complaints); silted oil-water separators and inlets on Doral and Hialeah industrial sites that haven't kept up with the MSGP cadence; canopy-loaded inlets in Coral Gables and Pinecrest that flood during normal afternoon storms; and undocumented exfiltration trenches under aging Kendall and South Miami strip centers. None are exotic; all are cheaper to fix on a planned cadence than during an enforcement letter or a recert deadline.

We work bilingual on-site coordination across the county and structure portfolios for the property-management firms running Class-A office, hospitality, and condo associations across multiple Miami-Dade cities.
