Terra Group and Suntex Marinas are back at the Miami Beach Marina with a fresh redevelopment pitch, filing new plans to scrap the low-slung, three-story retail complex on Alton Road in favor of a 14-story commercial tower and revamped marina campus. The proposal calls for a bigger garage, a trimmed-down retail footprint, and ground-floor space reserved for shops and Monty’s Sunset, breathing new life into a site where voters previously shut the door on housing.
What the filing lays out
According to The Real Deal, the application details a 14-story building with three levels of parking topped by roughly 10 floors of office space, plus ground-floor retail and a small police substation. The Real Deal also reports that the plan would shrink the total retail area and significantly increase parking capacity as part of a multimillion-dollar overhaul of the marina.
Background: the fight that already happened
City records from the Marina Park project show that this same stretch of waterfront, generally described as the 300–390 Alton Road site that includes 344 Alton Road, has already been through a bruising public debate. In 2020, voters narrowly rejected a residential tower on the site while signing off on a long-term lease for marina upgrades. Those resolutions spelled out conditions for any future sale or lease of air rights and anticipated major marina improvements as part of a public process, according to City of Miami Beach records.
How the new plan differs
Instead of the previously floated 38-story condo tower, the new application pivots firmly to office space and pulls back on retail, carving out a smaller shopping footprint while boosting parking and marina-related infrastructure. The filing presents these changes as part of a broader marina upgrade, including improvements to the baywalk and a proposed long-term lease with the city.
Marina size and operations
Public marina directories list the Miami Beach Marina at roughly 400 slips, capable of hosting vessels up to about 250 feet, a figure that aligns with operator materials for the facility. The developers are planning multimillion-dollar dock and Baywalk upgrades alongside the replacement of the existing building, according to the materials and filings released so far.
Legal path and public vote
Because the property is city-owned and the earlier Marina Park resolutions tied major changes to voter approval, any redevelopment that involves selling air rights or signing a long-term lease will need sign-off from both the city commission and Miami Beach voters. The 2020 resolutions laid out those procedural steps and the public-benefit requirements attached to any such agreement, as detailed in the city’s Marina Park documentation.
Oversight questions and community concerns
The Marine & Waterfront Protection Authority has asked to be involved in lease oversight after the city’s inspector general highlighted alleged lease-payment and compliance issues involving the marina operator. That request, included in a city letter calling for stronger oversight, signals active local scrutiny of how the marina is managed and of the terms of any new long-term deal, according to city correspondence.
Next steps and context
The newly filed proposal now heads into the city’s review pipeline, where the developers will need municipal approvals and likely a public referendum before anything gets built. Terra is already one of Miami Beach’s busiest developers, including work on a major hotel near the convention center with Turnberry after securing construction financing. Observers say that footprint helps explain the company’s continued interest in the marina site. PR Newswire reported the hotel financing last year.
