St. Charles Parish voters will be asked April 4 to allow the Louisiana hospital to borrow $11.5 million to build a new emergency room and make other capital improvements. Hospital CEO Federico Martinez Jr. said passing the proposal would allow the hospital to extend the repayment period of a $6.3 million loan to build its recent three-story expansion from seven years to 20. The balance would be used to build a new emergency room and lab, as well as other capital improvements.
