Road Code

The County Code – Chapter 49. Streets and Roads – governs the construction of public roads. The road standards used to provide greater detail for the construction of these roads are also included as CHAPTER 49. STREETS AND ROADS – REGULATIONS. These standards are applied according to the Rural, Suburban, and Urban designations that have been adopted by the County Council.

Road Code Areas

The County Council has idenfitied each area of the County as urban, suburban, or rural for road code purposes:

  • Urban Road: a road segment in or abutting a Metro Station Policy Area, Town Center Policy Area, or other urban area expressly identified in a Council resolution. See a map of urban road code areas.
  • Rural Road: a road segment located in a rural policy area as defined in the County Growth Policy; and
  • Suburban Road: a road segment located elsewhere in the County.

A map of the road code areas is shown below. Detailed maps are provided of each of the 17 road code urban areas.
