Part of that facade fell off the building on Wednesday.

The Natatorium, 111 12th St. N., will remain closed until a structural assessment can be completed and temporary repairs are finished, according to the city.

Park and Recreation staff became aware of the issue a few months ago and had a structural engineer working on an assessment and recommendation for a temporary fix, according to Patty Rearden, deputy director.

Some pool fees proposed to increase 50 cents

The issue doesn’t pose a public safety issue, Rearden said, but could cause roof damage if the facade failed. CTA was doing the assessment and staff was waiting for the results when the facade fell this week. Rearden said a funding source hasn’t yet been identified and staff is waiting on cost estimates before finalizing the plan.

It’s unknown when the facility will reopen, but it’s anticipated the repairs can be made within the next several days, according to the city.

In 2014, the city reduced operating hours and increased at the Natatorium in an effort to balance the maintenance needs at the facility.

The Natatorium was built in 1966 and is beyond its expected lifespan, city officials have said in the past.
