John Ball Zoo has unveiled early plans for a large-scale waterfront aquarium and wetlands campus on a 190-acre property in Walker near Wilson Avenue and Butterworth Street — a site that previously housed the Fenske Landfill. The concept includes a 60-foot-tall aquarium with multiple levels, immersive exhibits, and a walkable green roof, surrounded by trails, wetland walkways, and conservation-focused spaces for public education and research.

The estimated cost of the project is $370 million, with funding expected to come from a mix of fundraising efforts and support from local, state, and federal sources. The development is projected to generate a $2.9 billion net economic impact on Kent County over 10 years and draw over one million visitors in its first year alone.

Highlights of the proposed design include deep-water tanks, coral reefs, and an interactive sturgeon exhibit. The plan also incorporates public wetlands and trail connections between Kent and Ottawa counties. The zoo is working with the state on environmental testing for the former landfill portion of the site to determine future use.

If timelines hold, the aquarium could open as early as 2031.
