Stormwater Inlets and Piping in Miami, FL

Who This Service Is For

Stormwater inlet and piping services in Miami-Dade County are essential for developers, general contractors, commercial property owners, and anyone needing comprehensive stormwater collection and transport systems in Miami-Dade County.

Whether you're developing a new property in Doral, upgrading existing stormwater systems in Aventura, or installing comprehensive drainage infrastructure in Coral Gables, stormwater inlets and piping effectively collect and transport runoff. We coordinate contractors with expertise in Miami-Dade County drainage requirements, DERM regulations, the 25-year, 3-day storm event design criteria, and FPLOS/WQLOS standards to install inlet systems and underground piping that meet regulatory requirements.

Miami-Dade County Stormwater Inlet Considerations

Stormwater inlet and piping installation in Miami-Dade County requires specialized knowledge of local conditions and regulatory requirements:

• DERM as Primary Reviewing Authority: DERM (Department of Environmental Resources Management) serves as the primary reviewing authority for stormwater infrastructure projects in Miami-Dade County. Stormwater inlet and piping installation requires DERM Plan Review Approval for projects requiring Miami-Dade Review under Chapter 24. DERM regulates stormwater management through comprehensive standards that address drainage infrastructure, including inlets, catch basins, and piping systems.
• 25-Year, 3-Day Storm Event Design Criteria: Miami-Dade County requires developers to design stormwater systems for the 25-year, 3-day storm event as a baseline design standard. Stormwater inlet and piping systems must be sized to handle this design storm, with proper storage volumes and discharge rates to meet both Flood Protection Level of Service (FPLOS) and Water Quality Level of Service (WQLOS) standards. This requirement ensures infrastructure can handle significant rainfall events while maintaining system functionality.
• FPLOS and WQLOS Standards: Miami-Dade County's stormwater management criteria include two primary components: Flood Protection Level of Service (FPLOS) and Water Quality Level of Service (WQLOS). FPLOS protects public safety and property, while WQLOS maintains water quality in local waterways, particularly Biscayne Bay. Stormwater inlet and piping systems must be designed to meet both components.
• On-Site Retention with Groundwater Recharge: Miami-Dade County's approach emphasizes on-site retention with groundwater recharge rather than simple detention and controlled discharge. Stormwater inlet and piping systems should be designed to encourage water infiltration into the aquifer rather than rapid removal from the site, supporting aquifer recharge and reducing stress on the county's stormwater infrastructure.
• High Water Table: Miami-Dade's high water table, which can be within 2-3 feet of the surface in many areas, affects piping installation and requires proper depth control and material selection. Piping systems must be designed to function effectively in high water table conditions, especially in areas like Miami Beach, Aventura, and coastal neighborhoods.
• SFWMD Environmental Resource Permits: Stormwater inlet and piping systems may require SFWMD environmental resource permits for stormwater management, especially for systems connecting to surface waters or involving significant land disturbance. We coordinate all required SFWMD permits.
• Flood Zone Compliance: Stormwater systems in flood zones (AE, VE, AH, AO) must comply with FEMA requirements and Miami-Dade building codes. Systems must be designed to function during flood events and prevent flooding, with proper elevation of inlets and piping to meet Base Flood Elevation (BFE) requirements where applicable.
• Pipe Material Selection: Pipe materials must be suitable for Miami-Dade County conditions including high water tables, coastal environments, and soil conditions. Material selection affects system longevity and performance, especially important in coastal areas with saltwater intrusion and unique soil characteristics.
• Maintenance Requirements: Stormwater systems require periodic maintenance including cleaning catch basins, removing debris, inspecting piping, and maintaining outfalls. Access points and maintenance features must be included in system design, with compliance with Miami-Dade County requirements for long-term operation.

The Stormwater Inlet and Piping Installation Process in Miami-Dade County

Our coordinated approach ensures your stormwater inlet and piping system is installed properly and meets all Miami-Dade County regulatory requirements:

1. System Design: We coordinate with engineers to design stormwater inlet and piping systems that meet Miami-Dade County drainage requirements, the 25-year, 3-day storm event design criteria, and regulatory standards including FPLOS and WQLOS. Design determines inlet placement, pipe sizing, slopes, and connections, with priority on on-site retention and groundwater recharge.
2. Miami-Dade Permit Coordination: We help identify required permits including DERM Plan Review Approval (for projects requiring Miami-Dade Review under Chapter 24), SFWMD environmental resource permits for stormwater management, RER building permits, and coordinate with regulatory agencies. Permits ensure compliance with regulatory requirements and may require specific design features.
3. Contractor Selection: We match your project with licensed contractors who have the right equipment and experience for stormwater inlet and piping installation in Miami-Dade County, including expertise with high water table conditions, DERM requirements, and FPLOS/WQLOS standards.
4. Inlet Installation: Contractors install catch basins and stormwater inlets at specified locations, meeting Miami-Dade County construction standards. Installation includes proper placement, connections, and surface restoration, with proper sizing for the 25-year, 3-day storm event.
5. Piping Installation: Underground piping is installed with proper slopes and connections, sized for the 25-year, 3-day storm event and meeting FPLOS/WQLOS standards. Piping installation includes trenching, pipe placement, connections, and backfill, with consideration of high water table conditions.
6. Connection to Retention Areas: Piping systems are connected to retention ponds, detention basins, or outfalls, with priority on on-site retention and groundwater recharge as required by Miami-Dade County. Connections ensure proper water discharge and compliance with stormwater management requirements, meeting FPLOS and WQLOS standards.
7. Final Inspection: We coordinate final inspections with DERM, SFWMD, and Miami-Dade RER or municipal building departments to ensure stormwater systems meet specifications and regulatory requirements including FPLOS and WQLOS standards. Systems are ready for operation after final approval.
