Several days after News 8 revealed taxpayers are not getting their money's worth from a local project funded by stimulus money, the city has launched a review of the program and is considering personnel changes.

In addition, News 8 has now obtained two state reviews that show the City of Dallas did not spend stimulus money correctly and must now repay thousands.

"It just again shows that the government doesn't do a good job with the taxpayers’ money," said Rep. Jeb Hensarling, (R), 5th District of Texas. “We never treat somebody else's money with the same respect we treat our own.”

On Thursday, News 8 uncovered exorbitant costs taxpayers are footing for items like light bulbs, water heaters and thermostats in Dallas' Weatherization Assistance Program. It's designed to weatherize homes of the low-income in an effort to reduce their utility bills.

A review of dozens of invoices paid by the city showed taxpayers bought single compact fluorescent light bulbs for as high as $8.10 each. A four-pack of the same brand and model sell for $5.85 at Home Depot.

Another contractor charged $1,500 for a 29-gallon Rheem water heater that sells online for as low as $381.

In addition, a thermostat for sale on the web at a cost of $33 cost taxpayers $120.

The prices don't include labor. Contractors bill that separately at up to $95 an hour.

At issue, what's reasonable to charge?

The city said the higher material costs include overhead, disposal and transportation. But, why does that come at a cost of up to a 400 percent markup from retail?

The city acknowledged it does not negotiate on prices for items but rather only compares what one contractor bids to that of another before settling on one to do the job.

"I don't know all the details," Hensarling said. "But, I do know enough to know the City of Dallas had better do some accountability."

The Texas Department of Housing and Community Affairs, which distributes the federal money and administers the weatherization program in Texas, has found more than 20 problems in three separate reviews - all of them critical of the state's WAP program for months. The reports - obtained by News 8 - cites poor organization, workmanship and record keeping among other things.

State monitors also questioned some of Dallas' costs and disallowed others.

Among the most worrisome, city contractors installed and charged for nine new refrigerators without ever proving the old ones were inefficient. The TDHCA said Dallas must repay $32,824 in material costs for not following the rules on the refrigerators and other items like dishwashers and doors.

The state also chastised managers of Dallas' program for not attending state training on weatherization.

But, in a memo to the city council on Friday, the day after News 8's first story aired, Assistant City Manager A.C. Gonzalez acknowledged to the council, mayor and senior city staff that the Weatherization Assistance Program has had "administrative deficiencies."

Gonzalez said the city created new protocols to better comply. He also added that a program review is now under way, which includes appropriate personnel actions.

Senior staff also pledged to the TDHCA that the city's program managers will receive proper state training.

Dallas said it also hired five new inspectors to keep a more consistent watch on work.

But, the city is challenging what the state wants it to pay back - conceding it will reimburse Austin for $14,424. Dallas officials claim they have documentation to prove other questionable items are allowed.

The city continues to spend more than a million dollars a month to weatherize homes, but it is still not negotiating sky-high material prices it pays, like the $8 light bulbs.
