Environmental Services in Miami-Dade County
Phase I Environmental Site Assessment
A Phase I ESA is the standard first step in commercial real estate due diligence. We conduct records reviews, site reconnaissance, and interviews following ASTM E1527-21 standards and EPA All Appropriate Inquiries (AAI) requirements. If you are buying, selling, financing, or refinancing commercial property anywhere in Miami-Dade County, a Phase I ESA protects you from inheriting environmental liability — and is typically required by your lender before closing.
Phase II Environmental Site Assessment
When a Phase I ESA identifies a Recognized Environmental Condition (REC), a Phase II ESA is the next step. We collect and analyze soil and groundwater samples to confirm the presence, extent, and concentration of contamination — giving you the data you need to negotiate, remediate, or walk away with confidence.
NPDES Stormwater Permits
Construction projects in Miami-Dade County disturbing one or more acres of land require coverage under Florida’s NPDES Construction General Permit. Moran Rocks prepares Stormwater Pollution Prevention Plans (SWPPPs), assists with BMP implementation, and supports ongoing compliance documentation throughout your project.
Petroleum Contamination Cleanup
Miami-Dade County has one of the highest concentrations of active and historical petroleum storage tank sites in Florida. From the industrial corridors of Hialeah and Medley to the former gas stations scattered throughout Little Haiti, Little Havana, and the Miami River district, petroleum contamination is a routine finding on Phase I ESAs across the county. Moran Rocks brings direct field experience in Miami-Dade petroleum site assessment and FDEP Petroleum Restoration Program (PRP) reporting — coordinating assessment, cleanup planning, and regulatory submittals to move your site toward closure efficiently.
Why Miami-Dade County Clients Choose Moran Rocks LLC
Environmental consulting in Miami-Dade County requires more than general environmental knowledge. The county’s regulatory environment involves both FDEP and the Miami-Dade Department of Environmental Resources Management (DERM) — a local agency with its own permitting authority, inspection program, and enforcement history that operates independently of state oversight. Navigating both agencies, understanding Miami-Dade’s unique geology, and knowing the environmental history of specific corridors and neighborhoods takes years of on-the-ground experience. Here is why clients trust Moran Rocks:
- Licensed Professional Geologist (LPG) — Nicholas Moran, PG holds Florida state licensure as a Professional Geologist, meeting statutory requirements for environmental professional services.
- Direct Miami-Dade field experience — Hands-on petroleum site assessment and FDEP PRP reporting in Miami-Dade County, including familiarity with DERM oversight requirements and local regulatory workflows.
- ASTM E1527-21 compliant reports — All Phase I ESAs meet current ASTM standards and EPA AAI requirements, ensuring your lender, attorney, and title company have what they need.
- Fast turnaround — Standard Phase I ESAs completed in 2–3 weeks. Rush services available for time-sensitive transactions.
- Direct, responsive communication — You work directly with Nick, not a project manager or junior associate. Questions are answered clearly and promptly.
Miami-Dade County’s Environmental Landscape
Miami-Dade County sits atop the Biscayne Aquifer, a federally designated sole-source aquifer and one of the most productive aquifer systems in the United States. The water table is extremely shallow across most of the county — often within one to three feet of the surface during the wet season — and the aquifer is highly transmissive, meaning contamination introduced at the surface can reach groundwater quickly and migrate laterally over large areas. This geology makes environmental due diligence especially consequential: releases that might be minor in other parts of the country carry elevated risk in Miami-Dade.
The county’s environmental history is layered and complex. The Hialeah and Medley industrial corridors contain some of the highest densities of petroleum storage tank sites and auto salvage yards in South Florida, with contamination histories stretching back to the 1940s and 1950s. The Miami River industrial district — between downtown Miami and the airport — has documented releases from marine fueling, industrial operations, and legacy dry cleaning operations. Miami International Airport and the surrounding industrial park carry histories of jet fuel storage and solvent use. The Opa-locka area includes a former Naval Air Station and associated CERCLA contamination that has influenced groundwater conditions in the northwest portion of the county. In South Miami-Dade — the Redlands, Homestead, and Florida City — decades of agricultural activity involving pesticides, herbicides, and fertilizers create a distinct set of soil and groundwater concerns that require familiarity with agricultural chemical histories, not just industrial site databases. Miami-Dade also requires consultation with DERM in addition to FDEP for many environmental matters — a regulatory layer that national firms unfamiliar with the county routinely underestimate.

Frequently Asked Questions
How much does a Phase I ESA cost in Miami-Dade County?
Phase I ESA fees in Miami-Dade County typically range from $1,500 to $3,500 depending on property size, complexity, and required turnaround time. Properties with complex histories — former gas stations, industrial sites, auto salvage yards, or agricultural land in South Dade — may require additional research time and fall toward the higher end of that range. Contact us for a site-specific quote; most quotes are provided within one business day.
How long does a Phase I ESA take in Miami-Dade County?
A standard Phase I ESA takes approximately 2–3 weeks from authorization to final report delivery. Rush turnaround options are available for time-sensitive closings.
Is a Phase I ESA required to buy commercial property in Miami-Dade County?
Florida law does not mandate a Phase I ESA for every transaction, but most commercial lenders require one before approving financing. Completing a Phase I ESA is also necessary to establish the Innocent Landowner Defense under CERCLA, which protects buyers from liability for pre-existing contamination they did not cause.
What role does Miami-Dade DERM play in environmental consulting?
Miami-Dade’s Department of Environmental Resources Management (DERM) operates as a county-level environmental regulatory agency with authority that runs parallel to — and sometimes in addition to — FDEP oversight. DERM issues its own permits, conducts inspections, and can issue Notices of Violation independently of FDEP. For many environmental projects in Miami-Dade, compliance with both agencies is required. Understanding how DERM’s requirements interact with FDEP’s is essential to navigating environmental due diligence and cleanup in the county correctly.
What environmental issues are most common on Miami-Dade County properties?
The most frequently encountered Recognized Environmental Conditions (RECs) on Miami-Dade Phase I ESAs include historical underground storage tanks (USTs) at former gas stations and auto shops — particularly in Hialeah, Medley, Little Havana, and along the Miami River corridor — dry cleaner solvent (PCE/TCE) releases, jet fuel impacts near Miami International Airport, and agricultural chemical histories on South Dade properties in the Redlands and Homestead areas. The extremely shallow Biscayne Aquifer means contamination from these sources can reach groundwater rapidly, making early due diligence especially important in Miami-Dade compared to other Florida counties.
