It was promised to open this summer but won't.
And what about the non-profit group Cleveland Aquarium Inc. that wants to open a new $50 million Cleveland Aquarium somewhere else in downtown Cleveland by 2012?
Or Great Lakes Aquarium of Cleveland Inc., a group that announced in January that it wants to build a $70 million aquarium on the lakefront on land occupied by the Port of Cleveland near Cleveland Browns Stadium, assuming the Port of Cleveland moved to East 55th Street?
Here's what a Jacobs spokesman tells Channel 3 News.
"We are still planning on opening it soon and are putting the last pieces of the puzzle together," said Paul Ertel, general manager of Nautica Entertainment, which is owned by Jacobs Investments.
Nautica is part of the Powerhouse complex, a complex that Jacobs completely renovated in 1988. The original Powerhouse building was constructed in 1897.
Jacobs and Marinescape NZ Limited are working together to put 123,000 square feet of aquarium exhibits, restaurant and banquet facilities, and an exhibit-related amphitheater in the entire lower level of the Powerhouse on the west bank of the Flats.
Ertel said the plan is to use the two existing smokestacks at the Powerhouse as "SeaTubes" to house some of the exhibits. The Marinescape-trademarked SeaTube is a horizontal, curved underwater tunnel offering panoramic views of marine life from under the sea.
On Wednesday, Jacobs announced that it is now completing the financing for the aquarium development project and it's being described as a "$50 million multi-phase development to be located in and adjacent to the Powerhouse," which would include Nautica.
Jacobs already secured a $2 million loan from the City of Cleveland for the project, which is to be paid back over 10 years at 3 percent interest.
Jacobs also confirmed that it received preliminary commitments for 100 percent of the financing for Phase 1 of the aquarium project, estimated to cost over $15 million.
Also on Wednesday, Jacobs announced the expansion of the Powerhouse's Windows on the River meeting/restaurant area and relocation of the Cleveland IMPROV to a new and expanded facility next to Shooter's on the Water in the Nautica complex to "pave the way for conversion of the Powerhouse as required for Phase 1 of the (aquarium) development."
Windows on the River also bought out the Powerhouse lease of Cyrus Waterfront Cafe and the assets of Rock Bottom Brewery in the Powerhouse to clear the way for the expansion and the aquarium.
Jacobs Entertainment Vice President of Development David C. Grunenwald said, "Our downtown location, with parking for over 2,000 vehicles and proximity to venues like the Nautica Queen, our 400-patron cruise ship, and Nautica Pavilion, a 5,000-seat concert pavilion, will attract all types of additional events, large and small."
So now construction for the Powerhouse aquarium, not the opening, will begin this summer. Although it has built aquariums around the world, this will be Marinescape's first North American aquarium.
The aquarium will place special emphasis on integrating the historical building's architectural elements. The overall project, planned for a total of 22 acres, will also feature exhibits on the Great Lakes, Lake Erie, the Cuyahoga River, a freshwater Asian exhibit and a Discover/Education exhibit.
It is expected to attract 400,000 to 500,000 visitors a year to Cleveland, make a $9.6 million to $27.2 million local econmic impact and create 40 full-time jobs with a payroll of $1.6 million, according to a Jacobs spokesman.
And the other aquarium plans that have been floated? Where do they stand?
The non-profit Cleveland Aquarium Inc., which has been around for about 10 years, is still looking for a downtown site and wants to start fund-raising for private and corporate donations by the end of 2010.
Cleveland Aquarium Inc. has experts from the Cleveland Metroparks Zoo and officials who were involved with the old Cleveland Aquarium.
When the Cleveland Aquarium at Gordon Park near East 55th Street closed in 1985, the fish were moved to the Cleveland Metroparks Zoo. The former Cleveland Aquarium at Gordon Park opened on Sept. 6, 1954. It was expanded in 1967 and again in the 1970s.
Possible locations for a new Cleveland Aquarium that have been discussed in the past include the North Coast Harbor, near the Rock and Roll Hall of Fame and Museum, the Great Lakes Science Center and Browns Stadium.
The Cleveland Aquarium group hired Boston-based architect Peter Chermayeff, to design a 125,000-square-foot facility.
According to reports from the early 1990s, the original city plan for the North Coast Harbor on Lake Erie included the Rock and Roll Hall of Fame & Museum, the Great Lakes Science Center and the Great Waters Aquarium, according to City of Cleveland records.
The "Great Waters Aquarium" was being promoted by Cleveland's then-Mayor Michael White but no funding for it ever materialized.
The Great Lakes Aquarium of Cleveland is the idea of two 1972 Berea High School graduates Bruce Gulke and Russ "Rusty" Hill. They have an initiative to create the Rock Harbor Aquarium of Cleveland.
Their Facebook page -- The Great Lakes Aquarium of Cleveland -- touts the fact that many people want a new aquarium so the interest is very high.
None of the other aquarium projects has ever reached the funded stage in any way.
