ORANGE COUNTY, Fla. -- She's never seen public money handled so poorly. That's how the Orange County comptroller Tuesday described the review she just completed on the Expressway Authority.

The audit found the toll agency lost millions by paying sales taxes it didn't have to pay, but that's not all. Comptroller Martha Haynie said the record-keeping has been so poor, she doesn't even know the extent of the worst she's ever seen.

After almost 20 years on the job, she called what's in the 137-page report shocking. The Expressway Authority oversees 100 miles of roads that bring in $193 million in tolls every year and, according to the county's top watchdog, they don't do it well. "The depth and breadth, the pervasive lack of oversight, lack of control, was like nothing we've seen before," Haynie said.

For example, the toll agency paid more than $500,000 dollars to one company for maintenance work on the toll roads that it was already paying another company to do. The audit showed that the agency could've saved millions of dollars in sales taxes by purchasing more of its own materials, rather than having the contractors do it. And the audit singled out a $57,000 payment to a team-building company for 24 days worth of telephone coaching at $2,400 a day.

"There's a lot of details here that need to be addressed. We've already started the process of addressing those in a major way," Orange County Mayor Rich Crotty said.

Crotty said he asked for the audit and said the Expressway Authority has already hired a purchasing director to cut costs and is hiring an internal auditor. He and the board were about to ask for a toll increase before the audit started.

"The tolls haven't been raised in 16 years and I have no plan to change that," Crotty said Tuesday.

The comptroller said it's encouraging that the agency has already started making improvements and wants to fix the other problems by the end of the year.
