Terra’s proposed makeover of the former Miami Seaquarium would bring a new aquarium, a public waterfront walkway, restaurants and a marina to Virginia Key. But the long-term redevelopment lease hit a delay in county review on November 10, 2026.
Miami-Dade commissioners serving on the Recreation, Tourism, and Resiliency Committee voted 3–1 to defer the matter, according to WLRN. The proposed 99-year agreement was not finalized by that vote.
What Terra proposes for the site
The county’s proposed lease package describes a marine and waterfront destination with:
- A new aquarium without marine mammals.
- An education, conservation and research center.
- A marina and fisherman’s village with shops and food and beverage establishments.
- A public Baywalk, green spaces and a kayak and canoe launch.
- Preservation and adaptive reuse of the historic Buckminster Fuller dome, along with preservation and repurposing of the Flipper House.
Development publication OFTMW’s account of the design describes an 83,000-square-foot aquarium and a three-quarter-mile waterfront promenade. Those are proposed features, not completed facilities.
County project materials also describe a proposed partnership with the University of Miami for a permanent marine science facility. That should not be confused with an operating research center or a completed development.
Why the lease vote was delayed
The immediate dispute was about more than the project’s appearance. WLRN reported that the 249-page lease was made public the night before the hearing. Commissioners raised concerns about the time available for review and proposed waivers of advance-notice and appraisal requirements.
The marina is another major point of contention. Environmental advocates have raised concerns about boat traffic, manatees and seagrass in Biscayne Bay. The developer’s team has argued that marina revenue is important to making the marine attractions financially viable. Those competing concerns remain part of the debate; proposed environmental improvements are not proof that every impact has been resolved.
A lease assignment is not the same as final redevelopment approval
County records say commissioners approved assignment of the existing lease to Terra affiliate Resilient Aquarium LLC in December 2025 and directed staff to negotiate updated terms. The November 10 item concerned the proposed amended and restated agreement.
Under that proposal, the lease would ultimately expire 99 years after its effective date. The land would remain county-owned. Neither the earlier lease-assignment decision nor the latest renderings should be read as confirmation that the entire redevelopment is cleared for construction.
What residents should watch next
The next questions are whether the county approves the revised lease, what terms it adopts, and how the project addresses public access and environmental review. WLRN reported that the developer’s attorneys warned a delay could jeopardize the deal because of financing deadlines. That is a warning from the project’s representatives, not a confirmed cancellation.
For now, the useful distinction is between the destination Terra proposes and the approvals still being debated. The aquarium, waterfront access and research plans describe a possible future for the property—not an announced opening.
