Pavement Management Program

Owatonna's pavement management program ensures that the City's streets are maintained in top condition. Engineering staff continually work to track street conditions and plan maintenance schedules, which helps to keep costs at a minimum. It's used as a guide to determine when to construct, overlay, or seal coat existing streets, improve curb and gutters, or repair deteriorating pavement, Costs associated with managing the communities transportation system is partially funded through special assessments to property owners adjacent to the improvements.

Owatonna is committed to maintaining the City's streets in a cost efficient manner, ensuring streets are safe for all residents for years to come.

Infrastructure Design

Transportation System - Streets & Bridges

The City of Owatonna has approximately 162 centerline miles of city streets and the Street Department is responsible for maintenance, repair and snow plowing of those local streets and cul-de-sacs. It is also responsible for:

  • Maintaining traffic signals
  • Pavement markings
  • Stormwater Systems
  • Sanitary Systems
  • Street name and regulatory signs
  • Tree trimming along boulevards

The City of Owatonna has seventeen bridges located on the street system that are inspected and maintained to insure safe travel.

Transportation System - Signals

To determine when and if traffic signals may be needed (warranted), traffic engineers compare existing conditions against nationally accepted minimum guidelines - often called "warrants." When these warrants are met a traffic signal may be considered for installation. There are no requirements that a signal must be installed.

Traffic signals, like most things mechanical, will require periodic maintenance. One of the most common maintenance items is the changing of bulbs. If you observe a bulb out or what you perceive as a traffic signal malfunction please contact the city. To report any signals needing maintenance, call 507-444-4350
