A public hearing will be held this evening in Greenfield, with regard to an Adair County redistricting plan. Members of the Adair County Temporary Redistricting Committee are set to meet at 7-p.m. in the Adair County Boardroom at the courthouse in Greenfield, to discuss the redistricting plan, which became a requirement following the results of the 2010 census, which showed a population shift in Iowa.
