Savannah and Chatham County officials announced today that they have reached an agreement that could maintain the Savannah-Chatham police department for another 10 years. According to a memo sent to the county commission and city council Monday from county manager Lee Smith and city manager Stephanie Cutter, the new document will address complaints from unincorporated residents about limited police coverage. Officials with the two governments will officially announce that document at a press conference at 10 a.m.
