Construction on the largest indoor waterpark in America could start this summer in Minnesota and be ready for a 2024 opening.

The proposed 320,000 square-foot waterpark, called Mystery Cove, would be built next to the Mall of America by the Triple Five Group, owners of the mall, and would include water slides, beaches, food hall, and there are plans for an attached hotel. Construction could start this summer and the waterpark could be open by 2024.

Most major hurdles have been cleared at this point after the City of Bloomington approved much of the public funding for the project yesterday according to the Minneapolis / St. Paul Business Journal (paywall). The total cost of the project is expected to be around $422 million with about a quarter of that being public money, including $30 million for construction, money for public infrastructure improvements, and other costs including the construction of a parking ramp.

The agreement between Bloomington and the Triple Five Group requires that Bloomington residents get discounted ticket prices, they will save about 25% off the projected $60 ticket price.

There are still a few things to get settled before construction can start, like parking, skyway access, and of course, the final financing for the project needs to close.

Triple Five also owns The West Edmonton Mall in Canada, which is similar to the Mall of America, and it has a 215,000 square-foot waterpark that attracts around 500,000 visitors a year.

The waterpark would be located next to IKEA, across the street from the Mall of America, currently, there is just a giant parking lot there. The waterpark and the mall would be connected by a skywalk.
