Quad-City Times: Gov. Terry Branstad is floating a compromise he hopes will generate state money to address water-quality concerns while balancing future needs for school infrastructure and other conservation, resource protection and recreational purposes. Branstad said he would be open to repurposing the penny sales tax for school infrastructure set to expire 2029 by continuing the tax and splitting the ongoing proceeds with five-eighths going to education and three-eighths going into a natural resources trust that Iowa voters approved in 2010.
