Miami Beach, FL Environmental Rules: Stormwater Management (2026)

Miami Beach adopted a comprehensive Stormwater Management Master Plan (SWMMP) that addresses current and projected flooding from sea level rise, king tides, and storm events. The city has installed 70-80 stormwater pumps across the island and raised roadways 1.5-2 feet in vulnerable western neighborhoods along Biscayne Bay. All new development and substantial renovation must maximize unpaved landscape to allow stormwater infiltration. The city participates as a co-permittee with Miami-Dade County under the National Pollutant Discharge Elimination System (NPDES) program, requiring construction sites to implement erosion and sediment controls. Stormwater retention and treatment requirements apply to new impervious surfaces. The city has been awarded over $79 million in Resilient Florida grant funding for stormwater infrastructure improvements. Properties in Adaptation Action Areas face additional requirements for managing stormwater in the context of projected sea level rise. The Environment and Sustainability Department oversees stormwater compliance and coordinates with Miami-Dade DERM.
