It’s time for a fall cleanup on the streets of some cities in Iowa. Within the week, parts of Iowa are ready for snow, and that’s going to be a headache for city crews. Public works and police departments are getting tougher with owners of abandoned and inoperative cars who leave them on the streets when plows are due for a pass. Many cities tow away cars not moved by plowing time, and owners who don’t pay a fine to retrieve them lose the vehicles, which are then sold to dealers or auctioned off. In Davenport starting today (Monday), police will sweep the streets looking for junked, abandoned and illegally parked cars. Davenport police Captain David Struckman cites an ordinance requiring vehicles to be driven at least one mile every 24 hours.
