Frequently Asked Questions

How do I choose a road name?

All road names must comply with the following standards:

  • The road name cannot duplicate another road name elsewhere in the county. Similar sounding names, even when spelled differently, are considered duplicates.
  • Roads cannot be named after the surnames of living persons, except those named after family surnames that are prominent in county history, even if family members are still living. Documentation of historical significance is required when submitting this type of road name.
  • Road names, whether in English or a foreign language, must be grammatically correct, and easy to spell and pronounce. Staff will assign the appropriate road classification and this must be included on the road sign (street, way, etc.)
  • Road names, including punctuation, spacing and road classification shall be of a length to fit on a 36 inch sign blade (approximately 18 letters).
Do I have to provide road signs?

Any road with an official road name must be marked with a sign that is clearly visible and legible from the road. Road signs can be obtained from any sign vendor. The vendor must meet the county road sign specification M-4, which can be obtained from the Department of Public Works. If the road is maintained by the County, the road signs must consist of white lettering on a green background. For roads not maintained by the County, the signs must consist of green lettering on a white background.

The purchase and placement of road signs are the responsibility of the subdivider when a road is created a subdivision of land.

The purchase and placement of road name signs for all other roads are the responsibility of the party(ies) requesting the road name (applicant). If the road is maintained by the County, the road name signs will be maintained by the County. If the road is maintained by another agency (road maintenance agreement, homeowner’s association, community service district, etc.) the signs will be maintained by that entity.

If the road is not maintained by either the County or another agency, the road name signs must be maintained by the applicant.

Road name signs must be placed outside of the public right-of-way.
