Miami-Dade County Utility Trench Considerations

Utility trench excavation in Miami-Dade County requires specialized knowledge of local conditions and regulatory requirements:

• Utility Permits for Public Rights-of-Way: For utility trench excavation work involving water, sewer, and electrical systems in Miami-Dade County's public rights-of-way, utilities must obtain a Utility Permit prior to starting any construction. The utility must comply with all Miami-Dade County policies, procedures, and directives for the installation, placement, or removal of conduits, cables, poles, pole lines, facilities, and appurtenances.
• Public Works Right-of-Way Permits: Utility trenches in roadways or public rights-of-way require Public Works Right-of-Way Permits from Miami-Dade County. As of October 1, 2025, Miami-Dade has implemented electronic permitting systems that allow customers to submit applications, upload documents and drawings online, pay fees, and track applications throughout the review process.
• Water & Sewer Permits: Water and sewer utility infrastructure work requires Water & Sewer permits from Miami-Dade County and may require hydraulic analysis requests. Unlike electrical utilities, water and sewer utilities are not exempt from Florida Building Code permit requirements and must obtain proper permits for infrastructure work.
• RER Department Approval: When permits require review and approval by the Miami-Dade County RER (Regulatory and Environmental Resources) Department, applicants must seek approval from the County before proceeding with their projects. This review process is a required step for projects that fall under RER jurisdiction.
• Electrical Utility Exemptions: Electric utilities' structures or facilities directly involved in the generation, transmission, or distribution of electricity are exempt from Florida Building Code permit requirements in unincorporated Miami-Dade County. However, this exemption does not apply to water and sewer utilities, which typically require permits for their infrastructure work.
• Sunshine 811 Utility Location: Florida law requires utility location before excavation to prevent damage to existing utilities. We coordinate with utility companies through the Sunshine 811 system to locate and mark all underground utilities. Utility location is required and protects both existing utilities and excavation workers.
• High Water Table and Dewatering: Miami-Dade's high water table, which can be within 2-3 feet of the surface in many areas, may require dewatering for deep trenches. DERM Class V Permits are required for temporary dewatering to ensure that sediment, turbidity, and contaminants are removed before discharge. Water management ensures dry working conditions and prevents trench collapse, especially in areas like Miami Beach, Aventura, and coastal neighborhoods.
• Coastal Soil Conditions: Coastal areas in Miami-Dade including Miami Beach, Key Biscayne, Bal Harbour, and Aventura have unique soil characteristics including sand, limestone bedrock, and organic materials that affect trenching methods and stability. Soil conditions determine shoring requirements and trenching techniques.

The Utility Trench Excavation Process in Miami-Dade County

Our coordinated approach ensures your utility trench excavation is completed safely and meets all Miami-Dade County specifications and regulatory requirements:

1. Utility Location: We coordinate with utility companies through Sunshine 811 to locate and mark all existing underground utilities before excavation begins, as required by Florida law. Utility location prevents damage and ensures safe excavation, especially important in Miami-Dade County where utility infrastructure is extensive.
2. Miami-Dade Permit Coordination: We help identify required permits including Utility Permits for public rights-of-way, Public Works Right-of-Way Permits for trenches in roadways, Water & Sewer permits for water and sewer infrastructure, RER Department approval when required, DERM Class V Permits for dewatering if needed, and coordinate with regulatory agencies. As of October 1, 2025, permits can be submitted through Miami-Dade's electronic permitting system.
3. Contractor Selection: We match your project with licensed contractors who have the right equipment (trenchers, excavators, dewatering systems) and experience for utility trench excavation in Miami-Dade County, including expertise with high water table conditions, coastal soils, and utility coordination.
4. Dewatering Setup: For trenches requiring dewatering, contractors set up dewatering systems in compliance with DERM Class V Permit requirements, ensuring sediment, turbidity, and contaminants are removed before discharge. This is especially important given Miami-Dade's high water table.
5. Precision Trenching: Contractors perform trench excavation to exact depths and widths, meeting Miami-Dade County and utility company requirements, with proper safety measures. Trenching prepares areas for utility installation with proper depth control, accounting for Miami-Dade's high water table and coastal soil conditions.
6. Trench Bedding: Trench beds are prepared with proper bedding material for utility placement, meeting Miami-Dade County and utility company specifications. Bedding ensures stable utility support and proper drainage, especially important given Miami-Dade's sandy and limestone soil conditions.
7. Utility Installation: Utilities are installed in prepared trenches by utility contractors or specialized installers. Installation follows utility company specifications and code requirements, with coordination for inspections as required.
8. Backfill and Restoration: Trenches are backfilled with proper compaction and surface restoration, meeting Miami-Dade County requirements. Backfill ensures proper utility support and restores surface conditions, especially important given Miami-Dade's high water table and potential for settlement.
