 The Carroll County Commissioners have come out against this project, and McKay is urging his colleagues to do the same. Public hearings are expected to be scheduled in two bills, which were formally introduced to the Frederick County Council on Tuesday. One piece of legislation would set up a temporary moratorium on residential development in areas where schools are overcrowded. It will allow the school system time to build additional classroom space to handle more students. A second bill would establish a property tax credit for rehabilitation work on historic properties.
