Learn MoreMiami Drainage Challenges
Miami's dense urban environment and coastal vulnerability create unique drainage engineering challenges. The city requires PE-sealed Drainage Statements for all impervious surface additions, and the Impervious Surface Ordinance adds city-specific requirements on top of Miami-Dade County's Chapter 24 framework. Smaller projects must design for the 10-year/1-hour storm while larger developments must meet the 25-year/3-day standard, with 1/2 inch retention over the entire site.
City vs. county distinction
Miami defers to Miami-Dade County for much drainage regulation, but the Impervious Surface Ordinance and PE-sealed Drainage Statement requirement are city-specific.
Exfiltration trench engineering
Miami's dense urban environment drives demand for underground stormwater systems — exfiltration trenches, underground detention, and innovative below-grade solutions.
iBuildMiami portal
Streamlined digital permitting through the county system for all drainage permit submissions.
Dual storm standards
10-year/1-hour for smaller projects and 25-year/3-day for larger developments — designs must account for the correct standard based on project scope.

- Miami-Dade Public Works Drainage Manual
- Impervious Surface Ordinance
