About
SoFi
SoFi, located between South Pointe Park and the MacArthur Causeway, is a waterfront and residential Miami Beach neighborhood with a marina-lined shoreline and a calm, walkable street grid. The neighborhood’s character concentrates around Washington Avenue at South Pointe Drive, where sidewalk patios, design-forward dining rooms, and late-night lounges cluster near the park. Glassy condo towers and restored Art Deco blocks share views toward Government Cut and the cruise-ship channel. Smith & Wollensky anchors the point with steakhouse tradition and wraparound water views. Joe’s Stone Crab and Prime 112 set the tone for polished, reservation-driven evenings. South Pointe Park frames daily routines with lawns, a pier, and a wide promenade along the sand.

Intensive Mixed-Use Phased Bayside Commercial District
The commercial performance standards districts are designed to accommodate a range of business, commercial, office and hotel uses, as well as medium to high density residential development pursuant to performance standards which control the permissible type, density or intensity, and mix of development. Performance standards development will allow for modification of requirements affecting certain individual lots; greater flexibility, particularly for large-scale development; large commercial, medium to high density residential and mixed use developments in phases over time where the overall development at a single point in time or in a single instance by private owners would not be practical; providing incentives for provision of certain amenities and for conformance with specified objectives, thereby encouraging more flexible and innovative design and development in accordance with the goals and objectives of the comprehensive plan and the redevelopment plan.
