Mayor Dan Horrigan went public Thursday with a request that Akron’s residents and visitors give a little more of their paychecks.Upping the city’s income tax from 2.25 to 2.5 percent would raise $16 million more, all for safety forces and the annual paving of 43 more miles of Akron’s “terrible” city streets, Horrigan said, standing behind a foldout lectern in front of a row of uniformed police officers and firefighters.
