Miami-Dade Stormwater and SFWMD Environmental Resource Permits in 2026





Introduction to Stormwater and Environmental Resource Permits

Stormwater management and Environmental Resource Permits in Miami-Dade County govern the design, construction, and operation of stormwater management systems serving construction and redevelopment projects. The South Florida Water Management District administers the Environmental Resource Permit program for Miami-Dade County under Chapter 373 of Florida Statutes, with jurisdiction covering construction affecting waters of the state, wetlands, surface water management, and stormwater treatment. SFWMD ERP requirements coordinate with the federal National Pollutant Discharge Elimination System program administered by the Florida Department of Environmental Protection and with Miami-Dade DERM local stormwater review.





South Florida Water Management District Jurisdiction

The South Florida Water Management District is one of five regional water management districts in Florida, with jurisdiction over a 16-county area extending from Orlando to the Florida Keys including all of Miami-Dade County. SFWMD administers Environmental Resource Permits for activities affecting wetlands, other surface waters, and stormwater management. Permit thresholds typically apply to projects exceeding defined size thresholds for site area, impervious area, or wetland impact, with smaller projects proceeding under noticed general permits or exemptions. Coordination with SFWMD typically begins during the project design phase to confirm jurisdictional applicability and submittal requirements.





NPDES Construction-Phase Stormwater Pollution Prevention

The National Pollutant Discharge Elimination System program administered by the Florida Department of Environmental Protection requires construction-phase stormwater pollution prevention plans for construction sites with one or more acres of land disturbance. The Stormwater Pollution Prevention Plan addresses erosion and sediment control during the active construction phase, with required best management practices including silt fence installation around the perimeter of disturbed areas, inlet protection at adjacent storm drains, stabilized construction entrances, stockpile covers, and timely vegetation establishment on disturbed areas. The Notice of Intent for NPDES coverage is filed before construction begins, and the Notice of Termination is filed at construction completion.





Post-Construction Stormwater Treatment Design

Post-construction stormwater treatment design provides water quality treatment for ongoing stormwater runoff from the developed site, addressing pollutants typical of urban and developed land use including suspended sediment, nutrients, heavy metals, hydrocarbons, and pathogens. Treatment design under SFWMD ERP and DERM standards employs dry retention basins (where treatment volume infiltrates the soils between storm events), wet retention basins (permanent pool with treatment through settling and biological uptake), exfiltration trenches (subsurface infiltration), and detention systems with treatment components such as baffle boxes and sand filters. Design criteria specify the treatment volume calibrated to the contributing impervious area and the design storm event.





Quantity Management and Detention Design

Stormwater quantity management addresses the volume and rate of runoff discharge from developed sites, with design criteria typically requiring that post-development discharge rates not exceed pre-development rates for the design storm events. Detention design calculations apply runoff modeling using rainfall depth, soil infiltration characteristics, contributing drainage area, and outlet structure hydraulic design to determine the required storage volume and outlet structure dimensions. Underground detention systems including chamber systems and pipe galleries are increasingly common on space-constrained sites where surface detention basins are not feasible.





Wetland Mitigation and Buffer Requirements

SFWMD ERP review of projects affecting wetlands evaluates impact avoidance, minimization, and mitigation for unavoidable wetland impacts. Mitigation requirements typically involve creation, restoration, or enhancement of wetland habitat to compensate for impacts, with mitigation ratios calibrated to the type and quality of impacted wetlands and the type of mitigation provided. Wetland buffer requirements maintain undeveloped buffer zones around preserved wetlands, with buffer widths calibrated to the wetland type and adjacent land use. Mitigation banks operating in southeast Florida provide alternatives to project-specific mitigation in some cases.





Drainage Easements and Right-of-Way Coordination

Stormwater management facilities serving multiple parcels or extending across property lines typically require drainage easements documented in recorded easement instruments. Drainage discharge to public storm sewer systems requires coordination with the local municipality or Miami-Dade County for capacity verification and connection authorization. Construction in public right-of-way for drainage system installation requires right-of-way permits with appropriate restoration requirements. Coordination with Miami-Dade Public Works and the relevant municipal Public Works Department addresses interface between site drainage and the public drainage infrastructure.





Limestone Substrate and Exfiltration Design

Miami-Dade County's underlying Miami Limestone formation provides excellent infiltration characteristics for stormwater management design, with exfiltration trenches and dry retention systems performing well in typical site conditions. Site-specific percolation testing or assumed infiltration rates based on the regional geology guide the exfiltration design. Variability in limestone fracturing and karst features can affect infiltration performance, with geotechnical investigation recommended for larger sites. High groundwater conditions in coastal Miami-Dade limit available storage volume above the groundwater table, sometimes requiring deeper or more extensive exfiltration systems.





Operation, Maintenance, and Long-Term Compliance

SFWMD ERPs require ongoing operation and maintenance of the permitted stormwater management system, with maintenance responsibilities typically assigned to a property owners association, master association, or municipal entity depending on the project type. Operation and maintenance plans document the routine inspection, cleaning, and repair activities required to maintain system performance over time. Long-term compliance includes inspection reporting to SFWMD, repair of damaged or non-functioning components, and modification through permit amendment where system changes are proposed during ongoing operation.





Required Submittal Documents and Permit Review

A complete SFWMD ERP submittal for Miami-Dade County construction typically includes the permit application form, signed and sealed engineering documents covering the stormwater management system design, hydrologic and hydraulic calculations supporting the design, water quality treatment volume calculations, wetland delineation and impact analysis where applicable, mitigation plan where wetland impacts occur, operation and maintenance plan, and easement and ownership documentation. Coordinated submittals to Miami-Dade DERM for local review and to FDEP for NPDES coverage may proceed in parallel with the SFWMD ERP application.

1. Operation and Maintenance After the Permit Issues

The environmental resource permit obligates long after construction, with the stormwater system's operation and maintenance assigned to a responsible entity, the obligations typically transferring to the association when the developer's phase completes, and the inspections, certifications, and upkeep continuing for the system's whole life under the permit's conditions. The permit's obligations outlive the construction by decades. Managing the transfer and the upkeep keeps the compliance alive.
