This activity involves maintaining and repairing 420 miles of paved streets, 33 miles of paved alleys, 74 miles of unpaved streets, and 140 miles of unpaved alleys.
Paved street maintenance includes both streets and alleys, either concrete or asphalt. Street repairs handled by this division include pothole repairs, crack sealing, breakdown and blow up repairs, mud jacking, erosion control in the parking areas, and surface cut repairs for utility contractors.
Dirt street maintenance includes roadways as required and as requests are received. Although the abutting property owners must purchase gravel to be placed on streets and alleys, City personnel are available to blade the area at no cost. In addition, dirt street crews provide for the upkeep of drainage ditches.
Street cleaning is provided through the use of street sweepers and flushers. Streets are scheduled for cleaning five times per year, and paved alleys are cleaned once. Night hours are used to clean the commercial areas of the city, and residential areas are cleaned during the day hours. Personnel are available around the clock to take care of street cleaning emergencies which include vehicle accidents and removal of hazardous items in the roadways.
Bridges & Culverts
Various bridges over the Big Sioux, Floyd River, and Perry Creek are maintained by this division. Culvert maintenance, installation, and repair is another responsibility.
Snow & Ice Control
The goal of the snow and ice control activity is to maintain and operate an effective and efficient transportation network by providing a systematic snow and ice control program. A snow and ice control plan has been developed to facilitate this objective. The City's policy is to provide maximum service on major arterial streets and collector roads to safely and orderly move the traffic on the City's 420 miles of paved streets, 33 miles of paved alleys, 74 miles of unpaved streets, and 140 miles of unpaved alleys.
Signs/Signals/Barricades works directly with City Engineering staff to provide accurate traffic signs, properly functioning traffic signals and street lights, as well as safe work zone barricades for internal City projects. Staff is responsible for over 21,000 traffic signs, 140+ traffic signals, and approximately 1,700 City-owned street lights. They also oversee street/line painting, construction of new traffic signals, City fiber optic communication locates, and coordinate all other street light repairs with MidAmerican Energy.
