The Ames Police Department is increasing parking enforcement in Campustown as Iowa State University students return. Cmdr. Geoff Huff says they've spent the last few weeks working on parking regulation education, especially in the Greek community where parking is especially hard to find. He says parking officers will pay special attention to cars left on Campustown streets for extended periods in those four- and six-hour limit areas. The Ames City Council last month directed the police department to increase parking enforcement in Campustown.
