On Friday, the Columbus Zoo announced plans for a roughly 100,000-square-foot standalone aquarium that zoo leaders say will be the park’s next big-ticket attraction. Bankrolled by an estimated $50 million gift from a local family, the project represents the largest private donation in the zoo’s history and would significantly grow the zoo’s aquatic footprint. Officials are pitching the aquarium as a marquee piece of the broader One Wild World campaign to boost conservation, education, and tourism at the Powell campus. If it all comes together, the aquarium would build on the zoo’s current aquatic work and could become a heavyweight regional draw.
As reported by Columbus Business First, the planned facility would measure about 100,000 square feet, and the roughly $50 million donor gift is the largest in the zoo’s history. The outlet describes the project as part of a “transformational expansion” that zoo leaders and major donors are now publicly backing. That report also provides the first detailed look at the scope of the donation and the anticipated footprint of the standalone aquarium.
According to the Columbus Zoo website, zoo leaders previewed the news at a June 17 One Wild World event where they promised to “unveil an exciting next step” in the campaign. The site lists the Powell campus at 4850 W Powell Rd and offers background on the fundraising effort, but it does not yet share detailed renderings, construction phasing or an opening date. For now, the online materials mainly serve to rally support and keep the campaign in front of potential donors.
How this fits with earlier plans
The splashy aquarium announcement builds on the planning the zoo rolled out earlier this year. In March, Hoodline covered the zoo’s big splash with a $2.5 million state ask focused on an aquatic conservation and acclimation center, noting that a freestanding aquarium could follow. That earlier proposal described a smaller, behind-the-scenes facility meant to support freshwater mussel and fish propagation and acclimation work, with public exhibits envisioned as a later phase. Taken together, the two efforts signal a dual track: one aimed at research and conservation, the other at creating a high-profile visitor experience.
What’s next
How fast the aquarium moves from concept art to concrete will depend on funding, zoning, and design approvals, along with the usual gauntlet of permits. The zoo has also been weighing complementary development on the property, including a possible 130-room hotel as part of its longer-term growth plans, WOSU reported in May. The One Wild World campaign is expected to be the main vehicle for lining up the additional capital needed beyond the headline-making gift. So far, the zoo has not released a public timeline for schematic design, permitting, or an opening date.
For now, the roughly $50 million donation is the story: it gives the Columbus Zoo a substantial head start on a major capital project and leaves plenty of questions about construction details, exhibit plans, and how a new aquarium will fit into the region’s tourism ecosystem. The Columbus Business First exclusive offers the first public accounting of the donor size and project scope, and zoo leaders are expected to drip out more specifics as design work and fundraising gain momentum.
