A possible year-plus shutdown for the Olympics worries patrons of the Rose Bowl Aquatics Center

When they landed the diving competition for the 2028 Summer Olympics last year, operators of the Rose Bowl Aquatics Center in Pasadena trumpeted it as a gold-medal achievement. But swimmers and others who use the facility are now learning that pre-Olympic construction probably will force them out of three immensely popular swimming pools for more than a year.

The Aquatics Center will close as early as next April, and not be returned to its regular users until after the Olympics conclude in the summer of 2028, people with knowledge of the plans confirmed to The Times.

Such a prolonged closure will send the more than 400,000 people who pour through the center’s turnstiles each year scrambling to find other places to swim, dive, play water polo and aqua-aerobicize. The center’s two 50-meter pools and an adjacent therapy pool will be closed, along with two expansive hot tubs, the people said.

Aquatics Center operators declined to discuss details of the shutdown, saying they plan to make an announcement Monday. They said it’s premature for them to discuss what improvements the Games will bring to the 36-year-old swim complex, as those negotiations have not been concluded.

Jacie Prieto Lopez, vice president of communications for LA28, the Olympics organizing group, confirmed that improvements would be made to the facility but said specifics were still being sorted out.

“We cannot comment on specific facility improvements as those remain under active discussion between LA28 and the Rose Bowl Aquatic Center,” Prieto Lopez said “But based on initial evaluations of the existing facility, improvements could include the pool, diving tower and mechanical systems.”

Opened in 1990, in part with profits from the 1984 Los Angeles Olympics, the Aquatic Center was once viewed as a state-of-the-art facility. But it has grown somewhat shopworn and in need of a makeover. The operators of the center expect LA28 will pay for some of that work.

While LA28 officials wouldn’t discuss details, people familiar with their view said the Olympic organizers would balk at bankrolling every upgrade pined for by the city of Pasadena (which owns the facility) and the nonprofit that operates the center.

The massive deck around the swimming pools has grown rough in places. The locker rooms are cramped. Aged pumps and filters need an upgrade. Who should pay for these improvements has been the subject of prolonged discussion between LA28 and the Rose Bowl Aquatics Center operators, the people familiar said.

“At the end of the day, it’s going to be a win-win for LA28 and the Aquatics Center,” said one of the people, who wasn’t authorized to speak publicly. “The LA28 group is putting in a lot of investment. That should account for the fact the Rose Bowl will be losing revenue during the closure.”

Aquatics Center loyalists, however, wonder how they will cope with the loss of their pools.

“The pool helps me keep my weight down. It keeps my blood sugar down. It’s just everything to me,” said Elizabeth Ramirez, a social worker from Alhambra, after emerging from a morning aqua-aerobics class. “So when it closes down, it’s gonna definitely have an impact on my health. … Hopefully they will be able to tell us [about] another place where we will be able to go.”

Lynn Roberts, with one leg stunted by childhood polio, finds her time in the pool “life changing, because in the water I can do the things that everyone else does.” She knows that Rose Bowl is looking for alternative locations, but so far there are no details. The thought of the pool being closed for more than a year is “a big thing,” she said, adding “People are very, very concerned.”

Like a dozen other regulars, Bonnie Stern talked about the social hub the Aquatics Center creates. It’s been her gateway to new friendships, a walking group, brunches and even a regular happy hour.

“We’re all really concerned. There’s such a wonderful community here,” said Stern, who works in the entertainment industry. “We haven’t heard yet where we can go. And where are we going to be able to find what we have now?”

The complex also rents space to a cafe and a separate shop, the Swim Guy. Michael Eisenberg, who co-owns the swim equipment business with his brother, Craig, worries about losing clientele.

“We spent a lot of money setting this up and building our relationships with customers and teams,” Michael Eisenberg said. “The RBAC asked us if we could stay open and service the community during construction, but I don’t see how we can do that, since all our teams and the public will be scattered to different pools in the area. My brother and I are kind of freaking out about it about how best to serve the teams and the public and the financial cost of closing.”

Aquatics Center executive director Melanie Sauer said the nonprofit and its many user groups — for youth swimming, Masters swimming, water polo and more — are working fervently to find alternative pools. Rose Bowl Masters Swimming (to which the writer of this article belongs) already has launched new workouts at Occidental College in Eagle Rock and is talking to other pool operators.

The financial losses during the closure could be significant. The Aquatic Center reported $8.6 million in receipts from admissions, merchandise and services in 2024, the most recent year reported on its federal tax filings. Another $1.6 million came in via gifts, grants, contributions and membership fees.

Sauer said that an “RBAC on the Road” program will seek to draw payments from user groups when they relocate to other pools. She said it’s premature to provide any details of those arrangements.

Organizers of the Games announced the shift to the Rose Bowl center — in the Arroyo Seco just south of the more than 100-year-old football stadium — in September of last year. Previously, the Games planned to have divers compete at the LA84 Foundation/John C. Argue Swim Stadium, immediately southwest of the Los Angeles Memorial Coliseum, which will host track and field events.

But the Exposition Park pool, used for the 1932 Los Angeles Olympics, was not deep or wide enough for diving. And it would have proven more costly to retrofit than the Rose Bowl pool.

“This facility requires minimal work, provides additional amenities for athletes, and accounts for up to $17.6 million in revenue increases and cost savings,” LA28 said when it announced the shift to the Rose Bowl pool.

People familiar with the plans for the Pasadena complex say that Olympic diving fans will be seated in bleachers that will be erected atop the “competition” pool, which sits closest to the parking lot. Additional seats may wrap around the north end of the dive pool.

That pool’s 10-meter platform, originally constructed with a donation from the late televangelist Gene Scott, will be torn down and replaced. One plan being considered by LA28 organizers would eschew the existing locker rooms in favor of temporary modular structures, the sources said.

LA28 officials believe that any short-term losses to the center will be more than made up for by the long-term gains from the international attention the pools will receive and the promise that other major swimming and diving events will be held there, according to people who have spoken to the Olympic organization. LA28 officials point to an analysis by the Southern California Assn. of Governments that projected the Games will generate more than $17 billion in gross domestic product for the region.

Both the 2028 Games and those future events will help fill Pasadena hotels, restaurants and shops, bolstering the local economy and adding tax dollars to the city treasury, according to supporters of the plan. The pool is being considered as the site of the 2028 Olympic diving trials, one source said.

“This historic opportunity will shine a global spotlight on our community,” the Aquatic Center proclaimed last year. “We look forward to keeping you updated as more details become available.”
