Adding a Road to the City Road System

Process of Accepting a Road

Accepting a Road to the City Road System

Adding a road to the city road system would mean that all maintenance and snow removal would be managed through the city. More information on the process of adding a road to the city system can be found below.

 

Resident Interest

For residents with a concern or request to add a road to the city system, they may contact the city engineering department at 906-632-5734. Before any action is taken, the city will consider the following factors:

  • City Interest 
  • Economic and Public Benefit
  • Road Usage
  • Available resources
  • Future Impacts
  • Snow Removal
  • Potential Maintenance

 

Surveying and Research Needed:

In addition, the city may require technical documentation such as soils or environmental data produced by qualified professionals. All costs associated with preparation of the road for consideration shall be documented and the information provided to the city.

  • Road Widths and Surveys
    • Road rights-of-way for other than city primary roads shall be a minimum of sixty (60) feet in width.
    • All dead-end roads or streets shall have a “turn-around” with a minimum radius of one hundred twenty-five (125) feet.

  • Sight Distance, Grades, and Ditches
    • The minimum vertical sight distance shall be 400 feet.
    • The maximum permitted grade shall be 7%.
    • The width of roadbed shall be not less than 34 feet between shoulder points for non-primary roads.
    • Shoulder slopes shall be not less than 3 horizontals to 1 vertical with 4:1 preferred.
    • Ditch depth shall be a minimum of 1 foot below the shoulder point unless otherwise permitted by the City.
    • Back slopes shall be not less than 2:1.
    • In clay or silty soils, a minimum of a 24-inch sand subbase shall be provided beneath a crushed aggregate base.
