A plan to build a new, $1.3 billion Parkland Memorial Hospital will go before Dallas County voters in November. The hospital's board of managers has unanimously agreed to ask Dallas County commissioners to call a bond election as part of the Nov. 4 general election. Voters would be asked to underwrite about 60% of the new charity hospital's costs through the sale of general obligation and revenue bonds. For years, supporters of Dallas' charity hospital have been lobbying the county to replace the overcrowded, rundown facility.
