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. Our Florida-licensed professional engineer is on staff, so both the inspector certification and the sealed engineering come from the same team.

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.

Miami Beach is a barrier island with one of the most aggressive sea-level-rise adaptation programs in the country: raised roads, stormwater pump stations, tidal one-way valves, and elevated seawalls in Sunset Harbour, West Avenue, Indian Creek, and across South Beach. Properties there don't just need catch basins cleaned. They need to coordinate with the City's pump program and confirm that on-site tide flaps and check valves are actually seating.

Tidal water backs up the lowest inlets and outfalls, masking sediment and stuck flaps, so we schedule CCTV and outfall inspections at low tide when the pipe is readable. A full inlet, tide-flap, and on-site pump check in late September (before October's king-tide peak) is the cheapest insurance a Miami Beach building can buy. The inventory here is high-rise condo associations, hotels and hospitality, restaurants on Lincoln, Ocean Drive, and Collins, and medical and retail along 41st Street; we work after valet hours, coordinate with concierge, and never block the porte-cochère.

Coral Gables runs a City MS4 under FDEP NPDES Phase II inside the broader Miami-Dade RER (DERM) program. Two things make Gables stormwater unusual: the high water table near the Coral Gables Waterway and Biscayne Bay, which makes exfiltration trenches and dry retention marginal in places, and the city's mature live-oak and banyan canopy, which floods inlets with leaf litter and seed debris year-round. Most Gables commercial properties need quarterly cleaning at minimum, with extra service after fall leaf-drop and tropical-storm events.

The City enforces stricter aesthetic, signage, and tree-protection rules than most South Florida municipalities, which affects how we stage trucks, route hoses, and protect specimen trees. We use root-zone-aware staging and avoid hose runs against coral-rock and brick features. The mix is Class-A office along Ponce de Leon and Alhambra, hospitality at the Biltmore corridor, Miracle Mile and Merrick Park retail, and historic streets feeding the Waterway. All documented with debris volume, structure condition, and disposal manifests aligned to City MS4 and DERM expectations.
