Stormwater Management: Miami Beach vs Miami

Why does Miami Beach have such strict stormwater rules?

Miami Beach is a low-lying barrier island experiencing increasing tidal flooding from sea level rise and king tides. The city has invested over $500 million in stormwater pumps, raised roads, and drainage improvements to combat flooding.

Do I need to manage stormwater on my property in Miami Beach?

Yes. New development and substantial renovations must maximize pervious surfaces and manage stormwater on-site. The city's NPDES co-permit with Miami-Dade County requires construction sites to implement sediment and erosion controls.

What are Adaptation Action Areas in Miami Beach?

Adaptation Action Areas (AAAs) are designated zones where the city incorporates sea level rise adaptation strategies into land development regulations. Properties in AAAs face additional requirements for stormwater management and building elevation.

Does Miami charge a stormwater fee?

Yes. Miami charges a stormwater utility fee based on the impervious surface area on a property. Reducing impervious coverage through approved green infrastructure may lower the fee.

What stormwater retention is required?

New development must retain the first inch of rainfall on-site. The city's high water table and low elevation require specialized solutions such as exfiltration trenches.
