Road and access drive grading services in Miami-Dade County are essential for developers, general contractors, subdivision developers, commercial property owners, and anyone preparing roadways for paving or infrastructure installation in Miami-Dade County.
Whether you're developing a new subdivision in Homestead, building access roads for a commercial development in Doral, or upgrading existing roadways in Aventura, proper grading ensures water drains correctly, provides safe vehicle access, and meets engineering specifications. We coordinate licensed contractors with the right equipment and expertise for your specific Miami-Dade County project needs, including compliance with Miami-Dade DTPW (Department of Transportation & Public Works) requirements.
Typical Project Sizes in Miami-Dade County
Road and access drive grading projects in Miami-Dade County typically range from $30,000 to $100,000 for single access drives, and $100,000 to $500,000+ for subdivision road networks depending on length, width, drainage requirements, flood zone considerations, and site conditions. Projects in flood zones or requiring significant elevation adjustments often cost more.
What Road and Access Drive Grading Includes in Miami-Dade County
Crown Grading
Creating proper crown (center high point) in roadways to direct water to the sides and into drainage systems. Crown grading prevents water from pooling in the center of roads and ensures proper drainage flow, essential given Miami-Dade's heavy rainfall and flat topography. Typical crown height is 2-4 inches above the edges.
Cross-Slope Grading
Establishing proper cross-slopes (typically 2-3%) across road width to direct water to roadside drainage. Cross-slopes must be consistent along the entire road length for effective water management, meeting Miami-Dade DTPW specifications for subdivision roads.
Longitudinal Slope Grading
Grading along the road length to achieve proper longitudinal slopes (typically 0.5-6% minimum) for drainage while maintaining safe vehicle access. Slopes must balance drainage needs with vehicle safety requirements, meeting Miami-Dade County road construction standards.
Subgrade Preparation
Grading and compaction of subgrade material to proper elevations and density for base course and pavement installation. Subgrade must be properly graded to support road loads and prevent settlement, accounting for Miami-Dade's high water table and coastal soil conditions.
Drainage Feature Grading
Grading around catch basins, swales, and drainage inlets to ensure proper water flow into drainage systems. Road grading must work in conjunction with drainage infrastructure for effective water management, meeting Miami-Dade County requirements for curbs, gutters, and drainage structures.
Transition Grading
Smooth transitions between different road sections, intersections, and connections to existing roadways. Transition grading ensures smooth vehicle access and proper drainage flow at connection points, meeting Miami-Dade DTPW requirements for road connections.
Miami-Dade County Road Grading Considerations
Grading for roads and access drives in Miami-Dade County requires specialized knowledge of local conditions and regulatory requirements:
- Miami-Dade DTPW Standards: All streets within subdivisions must be constructed and surfaced in accordance with Miami-Dade County's "Specifications for Second Road Construction and Residential Streets" or the requirements outlined in the County's Manual of Public Works Construction administered by the DTPW. All street construction is subject to inspection by the governing body and requires permit issuance before work can proceed.
- Required Infrastructure: Road grading must coordinate with required infrastructure including curbs, gutters, drainage structures, and associated drainage systems according to standard specifications. Sidewalks are required in residential, multiple-family, and business areas, as well as along all arterial highways. Street name signs must be placed at all intersections and approved by the County's Director of Traffic and Transportation.
- Stormwater Management: Roads must be graded to direct water to stormwater inlets, swales, or retention areas to meet South Florida Water Management District (SFWMD) and Miami-Dade County requirements. Proper grading prevents flooding and reduces stormwater runoff into roadways, essential given Miami-Dade's heavy rainfall.
- High Water Table: Miami-Dade's high water table affects subgrade preparation and may require additional base course material or elevation adjustments. Proper drainage is critical to prevent water from undermining road foundations, especially in areas like Miami Beach, Aventura, and coastal neighborhoods.
- Flood Zone Requirements: Roads in flood zones may need to be graded to specific elevations above base flood elevation. This affects grading depth and may require additional fill material or elevation adjustments, particularly in coastal areas like Miami Beach, Key Biscayne, and Aventura.
- Guardrails and Traffic Barriers: Where streets are adjacent to or abut canals, lakes, or other bodies of water, guardrails or other traffic barriers must be installed to prevent vehicles from entering these water bodies. Road grading must account for these safety requirements.
- RER and DTPW Permits: Road grading requires permits from Miami-Dade RER (for unincorporated areas) or municipal building departments (for incorporated areas), and DTPW permits for subdivision roads. Projects may require additional permits from SFWMD for stormwater management. All construction is subject to inspection by the governing body.

The Road and Access Drive Grading Process in Miami-Dade County
Our coordinated approach ensures your road or access drive meets all specifications and regulatory requirements in Miami-Dade County:
- Project Review: We review your engineering drawings, road design, and site plans to understand grading requirements. This includes identifying drainage points, utility locations, flood zone considerations, and any site constraints specific to Miami-Dade County conditions.
- Miami-Dade Permit Coordination: We help identify required grading permits including Miami-Dade RER building permits (for unincorporated areas) or municipal building department permits (for incorporated areas), DTPW permits for subdivision roads, SFWMD permits for stormwater management, and coordinate with regulatory agencies. All street construction requires permit issuance before work can proceed.
- Contractor Selection: We match your project with licensed contractors who have the right equipment (motor graders, compactors, laser-guided systems) and experience for precise road grading in Miami-Dade County, including expertise with DTPW specifications and subdivision infrastructure requirements.
- Rough Grading: Contractors perform initial earthmoving to achieve approximate elevations and establish the general road profile. This establishes the basic grade and prepares the area for fine grading, accounting for Miami-Dade's high water table and coastal soil conditions.
- Fine Grading: Precise grading work using laser-guided equipment to achieve exact elevations and slopes specified in engineering drawings. Fine grading creates proper crown, cross-slopes, and longitudinal slopes, meeting Miami-Dade DTPW specifications for subdivision roads.
- Subgrade Compaction: Proper compaction of subgrade material to meet engineering specifications for road foundation support. Compaction testing ensures subgrade meets density requirements, accounting for Miami-Dade's unique soil characteristics including limestone bedrock and sandy soils.
- Final Inspection: We coordinate final grading inspections with Miami-Dade RER or municipal building departments, DTPW (for subdivision roads), engineers, and paving contractors to ensure the graded road meets all specifications, DTPW standards, and is ready for base course and paving. All construction is subject to inspection by the governing body or their designated representatives.
Frequently Asked Questions
What are Miami-Dade DTPW requirements for subdivision roads?
All streets within subdivisions in Miami-Dade County must be constructed and surfaced in accordance with the County's "Specifications for Second Road Construction and Residential Streets" or the requirements outlined in the County's Manual of Public Works Construction administered by the DTPW.
