News Summary
The John Ball Zoo is considering a significant aquarium project in Walker, targeting a 190-acre site with an estimated cost exceeding $350 million. The aquarium, projected for completion by 2031, aims to enhance wildlife protection and engage the community while generating significant economic benefits for the region. However, environmental challenges due to previous contamination at the proposed site remain a concern, requiring careful assessments before development. The project is expected to create around 2,500 jobs and contribute substantial tax revenue, making it a high-priority economic development initiative.
Walker, MI — John Ball Zoo is exploring the development of a large-scale aquarium on a 190-acre site in Walker, with a projected cost of over $350 million. The zoo’s CEO, Peter D’Arienzo, aims for the aquarium to open by 2031, hoping to enhance the zoo’s commitment to wildlife protection and community engagement while contributing significantly to the local economy.
The proposed site is located on the former Fenske landfill along the Grand River, an area that presents environmental challenges due to past contamination concerns. State environmental agencies have raised questions regarding liability and requisite cleanup efforts at the site, emphasizing the need for comprehensive assessments before development proceeds.
If successful, the aquarium is expected to generate a remarkable economic impact. Projections suggest that it could bring in over $3.4 billion in net economic benefits over its first eleven years, along with creating approximately 2,500 new jobs in the Kent County area. A study conducted in 2023 by Canopy Partners highlights that the aquarium could also contribute over $268 million in new state and local tax revenue shortly after its opening.
To finance the project, the aquarium may benefit from increased tax revenues generated by a successful 2024 ballot initiative aimed at raising the lodging tax in Kent County. This added revenue could aid in mitigating the financial burden of cleanup and development.
The aquarium seeks to position itself as a competitive attraction, rivaling major aquariums in other cities including Chicago, Atlanta, and Monterey. It aims to create an educational experience that connects with other regional attractions, fostering both tourism and community engagement.
The concept for the aquarium was originally proposed by the zoo in 2021. Since then, several locations were evaluated before ultimately narrowing the focus to Kent County in 2024, with the Walker site emerging as a leading candidate.
Currently, the property is under a due diligence period, and the zoo has an option agreement to purchase the site valid until May 2026. This agreement allows for further exploration of the site’s viability while addressing the environmental concerns that have been flagged.
As a high-priority economic development project, state officials are keenly interested in the aquarium’s potential. The project represents a significant step for the region not only in terms of economic revitalization but also in enhancing the community’s connection to wildlife and educational opportunities.
The historical usage of the Fenske landfill as a municipal landfill and industrial waste site adds complexity to the project. Necessary environmental assessments will be conducted to ensure that the site can be transformed into a safe and effective habitat for aquatic life and educational experiences.
As the John Ball Zoo moves forward with its plans, the success of the aquarium project could have lasting impacts on the Kent County area, bolstering economic growth and reaffirming the region’s commitment to conservation and education.
