WATERLOO -- A number of contractors are still waiting to be paid for various projects under way in Exchange Park.

But record Cedar River flooding in the park has washed away some of those improvements, including Riverfront Stadium, and caused significant damage to Waterloo's park system citywide.

"The invoice for painting the Waterloo Rowing headquarters, what used to be called the boathouse, just came through (Tuesday)," said Paul Huting, director of the Leisure Services Commission. "That building is being deemed a total loss by the insurance company."

Volunteers were helping clean Riverfront Stadium Wednesday, in hopes the Waterloo Bucks can return to complete their season soon.

"They're shoveling thick mud out of there," Huting said. "It's going to need a thorough cleaning, and we may need to hire a contractor to complete the work."

The stadium also experienced in excess of $100,000 in damage to its electrical systems and it appears the "party deck" is a complete loss. A structural analysis is being planned for the stadium itself.

While the city's insurance policy could help repair buildings, other structures may not be covered, including apparent damage to the fences and playing fields at the youth baseball and softball complex.

"Backstops twisted, dugouts tumbled over, fences leaning, infields washed downstream," Huting said. "We haven't assessed to total cost on that yet.

"The obstacles in the skate park floated up onto the fence and are hung up," he added. "We think that's going to be a total loss."

Officials are waiting for the water to fall before assessing a new trail running through Exchange Park and the disc golf course, which is known to have suffered some minor damage.

Safety material below several city play structures washed away and the city will be evaluating the playgrounds before opening back up.

Elsewhere in the Waterloo park system:

The Riverview Recreation Area, formerly known as the Mitchell Avenue sand pits, remains under water and likely suffered heavy damage. That includes the all-terrain vehicle riding trails operated by a nonprofit riding club.

"The area that was a riding trail is now a huge sand dune," Huting said. "I'm thinking there will probably have to be a complete redo of the riding trails in there and it will be closed indefinitely."

Two picnic areas being constructed in the southern, passive portion of the Riverview area are still standing but may have been damaged.

Lafayette Park, also known as Pat's Pond, is full of water and a new electrical service installed within the past two weeks has been destroyed.

The city had just let a construction contract for a $500,000 renovation of the park, which must be completed before September under guidelines of the federal grants being used.

"We don't know how this is going to affect our very tight timeline on the renovation," Huting said, noting the city has already begun the process of seeking an extension on the completion date.

Bontrager, Liberty, Cedar Terrace and Lower Gates parks all had damage that has yet to be assessed.

Young Arena, which is operated by Leisure Services, reopened for business as usual today.

Huting said the damage and repair costs are just part of the equation, noting many programs and fee-generating venues have been closed for periods of time.

"Lost revenue is substantial from this," he said. "We're already refunding fees for sports programs, shelter reservations ? and the golf courses were closed for several days."
