St. Regis Residences Brickell Clears First Gate for a Private Marina

Miami’s City Commission has cleared the way for Related Group and Integra Investments to pursue a submerged-land lease off the St. Regis Residences, Miami at 1809 Brickell Ave, the first procedural step toward adding a private marina to the roughly 50-story tower now under construction on Biscayne Bay.

Why it matters

A marina is the amenity that separates a $47 million penthouse from a merely expensive one, and developers are chasing it across the bay: the former Miami Seaquarium site and Virginia Key have marina proposals moving in parallel, and a private marina has been floated for a billionaire’s own waterfront holding. But a dock built onto private land is a building permit. A marina built onto submerged land the city or state owns is a lease, and a lease is a negotiation the developer does not fully control. The City Commission action clears developers to start submitting permits, it is not a permit itself. Everything that actually puts pilings in Biscayne Bay still has to happen: a Miami-Dade DERM Class I coastal permit for any work in tidal waters, a U.S. Army Corps of Engineers Section 10 review under the Rivers and Harbors Act, and, because the submerged land beneath a marina at this scale is typically state sovereign land, a lease from the state under the Board of Trustees process before the county or federal sign-off means anything.

The numbers

Related Group and Integra Investments have not disclosed a slip count or slip size for the proposed marina, and neither has filed the county or federal permit applications that would put a number on the record. The tower carries 152 residences, is expected to complete in 2027, and is under construction by Coastal Construction, with more than 65 percent of units reported in contract, including the $47 million penthouse. None of those figures answer what the marina will look like on the water; that detail arrives only when DERM and the Corps have an application in front of them.

What’s next

Watch three dockets, not one. Miami-Dade DERM’s Class I coastal permit filing will be the first place slip count and dredge footprint become public. The Army Corps’ Jacksonville District posts a public notice with a comment period once it has an application, which is also where any Biscayne Bay seagrass or manatee-protection conditions would show up. And the state submerged-land lease, negotiated separately from either, sets the rent and term the developer pays for water the city does not own outright. For anyone underwriting a waterfront amenity anywhere in South Florida, the lesson from St. Regis so far is that a headline commission vote buys the right to start applying, not the marina.
