Key Takeaways
- • Ken Griffin, Citadel founder, has submitted a request to add a private waterfront helipad at his Terminal Island megayacht marina development (120 MacArthur Causeway) in Miami Beach, pending zoning amendment approval expected at the Land Use Committee's Sept. 16 meeting.
- • The helipad proposal requires amending Miami Beach's land development regulations to classify private helipads as an "accessory use" within Terminal Island's industrial zoning district, sponsored by Miami Beach Commissioner Joseph Magazine.
- • Griffin's $175 million Lürssen superyacht *Defy* (308 feet) cannot be accommodated at his Star Island mansion despite $169 million in residential property acquisitions there, making the Terminal Island marina strategically essential for his ultra-luxury waterfront portfolio.
- • The approved marina development (30,000+ square feet) will feature eight megayacht slips (capped at four vessels simultaneously), owner's pavilion with private suite, separate crew pavilion, operations center, and rooftop swimming pool, designed by BMA Architects.

Summary
Billionaire hedge fund titan Ken Griffin has expanded his Miami Beach development ambitions by requesting approval for a private waterfront helipad at Terminal Island, the location of his recently approved megayacht marina at 120 MacArthur Causeway. The proposal, sponsored by Miami Beach Commissioner Joseph Magazine, is navigating the city's Land Use and Sustainability Committee and Planning Board, with a scheduled review at the Land Use Committee meeting on September 16, 2026.
To permit the helipad development, Miami Beach officials must amend the city's land development regulations to classify private helipads as an "accessory use" within Terminal Island's existing industrial zoning district. The helipad would provide exclusive aviation access for marina users, allowing them to circumvent Miami's traffic congestion while maintaining privacy—a premium amenity aligned with the ultra-luxury positioning of Griffin's waterfront portfolio.
The Terminal Island site represents a strategic acquisition from Jorge Pérez's Related Group, which had originally planned an office development on the 3.5-acre parcel. Griffin's marina development, designed by BMA Architects, features 30,000+ square feet of infrastructure including eight megayacht slips (operationally capped at four vessels at any given time), an owner's pavilion with private suite, a dedicated crew pavilion and operations center, and a rooftop swimming pool. This exclusive facility addresses a critical need: Griffin's 308-foot Lürssen superyacht *Defy*, acquired in 2024 for approximately $175 million, exceeds the berthing capacity of his Star Island mansion, despite his $169 million investment in residential property assemblage across Star Island.
The helipad request exemplifies Griffin's comprehensive South Florida real estate repositioning. Terminal Island's location—adjacent to a U.S. Coast Guard station, city maintenance yard, and Fisher Island ferry, and directly across the causeway from Star Island—creates an integrated ultra-premium waterfront ecosystem. This latest development enhancement underscores Griffin's broader expansion of Citadel operations in South Florida, combining residential, maritime, and now aerial infrastructure into a cohesive private ecosystem.
