Dallas County commissioners plan to sell $42 million in government bonds to help pay construction costs for the new Parkland Memorial Hospital. At Tuesday's weekly meeting, Commissioner John Wiley Price said he was concerned that the general obligation bonds would be repaid by taxpayers rather than by hospital revenue as originally proposed in 2008. "When we dealt with the voters, we talked about revenue bonds," he said. "There don't appear to be any revenue bonds" for the new hospital. The 2008 bond election allowed the county to issue $747 million in bonds to build the $1.27 billion public hospital.
