The Miami-Dade Department of Environmental Resources Management (DERM) reviews and permits construction activity that impacts environmental resources including water quality, wetlands, wellfields, and coastal areas. Many luxury construction projects in Miami-Dade County trigger DERM review in addition to standard building permits, often substantially extending project timelines.

This guide details Miami-Dade DERM permit requirements for construction projects across the county in 2026.



WHAT DERM REGULATES

DERM has jurisdiction over: wetlands and other environmentally sensitive areas, wellfield protection zones, coastal areas and beaches, stormwater management systems, water quality and surface water protection, contaminated sites and brownfield remediation, environmentally endangered lands, and prohibition on impacts to specific habitats. DERM works in conjunction with state DEP and federal EPA but maintains its own permit programs and standards. Many projects require both DERM and state permits.



WETLAND PERMITS

Wetland-related DERM permits include: wetland impact permits for any construction within delineated wetlands, mitigation plans for unavoidable wetland impacts, wetland creation or enhancement permits, and exotic species removal permits. Wetlands include freshwater hammocks, coastal wetlands, mangroves, and other defined areas. Wetland impact permits often require mitigation banks or onsite mitigation, adding substantial cost. Permit timeline typically 6 to 18 months.



WELLFIELD PROTECTION

DERM wellfield protection zones surround public water supply wells: Wellfield Protection Area zones with 30, 60, 90, 120, 180, and 210-day travel times to wells, prohibition on certain land uses within wellfield zones, restrictions on hazardous material storage, prohibitions on certain types of underground storage tanks, and substantial review for any construction within wellfield zones. Properties within wellfield zones face additional permitting and may have restricted use options.



COASTAL CONSTRUCTION

DERM regulates coastal construction in conjunction with state DEP: coastal construction control line projects require dual permits, beach dune impact prohibitions, sea turtle protection during nesting season (May 1 to October 31), erosion control structure review, and beach renourishment coordination. Coastal projects in Miami-Dade typically run 6 to 24 months for permitting before construction can begin.



STORMWATER MANAGEMENT

DERM stormwater requirements include: stormwater management plan for projects over defined size threshold, retention or detention pond design, water quality treatment for first inch of runoff, prohibition on direct discharge to surface waters in some cases, and compliance with Best Management Practices for construction stormwater. Most new construction over 10,000 square feet triggers stormwater review. Permit timeline typically 8 to 20 weeks.



TYPICAL DERM PERMIT COSTS

DERM permit costs vary widely by project type: stormwater management permits $500 to $3,000, wellfield protection permits $300 to $1,500, wetland impact permits $2,000 to $15,000+ plus mitigation costs, coastal construction permits $1,500 to $10,000+, and contaminated site permits $1,500 to $25,000+. Mitigation costs (wetland creation, exotic removal, restoration) frequently exceed permit fees significantly. Total DERM-related costs on large projects can reach $100,000+ in fees and mitigation.



TYPICAL TIMELINES

DERM review timelines depend on project complexity: stormwater permits 8 to 16 weeks, wellfield permits 6 to 12 weeks, wetland permits 6 to 24 months including mitigation negotiation, coastal permits 4 to 12 months including state DEP coordination, and contaminated site permits 12 to 36 months depending on remediation complexity. DERM timelines run in parallel with building permits but often determine total project timeline.



PROJECTS THAT TYPICALLY TRIGGER DERM REVIEW

Projects requiring DERM review include: new construction near water bodies or wetlands, projects in flood zones with substantial improvements, swimming pool construction near surface waters, new wells or significant earthwork, septic systems in environmentally sensitive areas, projects in wellfield protection zones, coastal construction within coastal construction control line, redevelopment of contaminated properties, and any project requiring substantial site grading or stormwater management.
