Frequently Asked Questions

Miami-Dade County Drainage FAQs

How much does drainage design cost in Miami-Dade County?
Miami-Dade drainage design typically costs $3,000 to $10,000 for residential projects and $10,000 to $50,000+ for commercial work. The county's Class I, II, and III permit system means costs vary by project complexity. Coastal projects with Coastal Construction Control Line requirements may be higher.
Do I need a permit for drainage work in Miami-Dade County?
Yes. Miami-Dade uses a tiered permit system: Class I for simple projects, Class II and III for more complex work. All drainage modifications require engineer-certified drainage statements following the Public Works Drainage Manual. The design storm standard is a 10-year, 1-hour rainfall (3.5 inches) with half-inch retention over the entire site.
How long does drainage permit approval take in Miami-Dade County?
Miami-Dade permit reviews through the RER ePermitting Portal typically take 3 to 6 weeks depending on project class. Class I permits are fastest, while Class III projects with DERM or SFWMD coordination may take 6 to 10 weeks. We navigate this process daily and achieve consistent first-time approvals.
What drainage services does StructureSmart offer in Miami-Dade County?
Our Miami-Dade services include residential and commercial drainage design, drainage statements per county manual requirements, coastal drainage solutions, sea level rise adaptation, permit navigation for all three permit classes, and bilingual support for our Spanish-speaking clients.
How does sea level rise affect drainage in Miami-Dade?
Sea level rise projections of 2+ feet directly impact long-term drainage design in Miami-Dade. The water table is extremely high (0-4 feet, often at surface level). Seepage systems like French drains and exfiltration trenches are primary solutions. Properties must meet Water Control Map or road crown elevation requirements for finished floors.
