9.3.3 Secondary Roadways

secondary roadways

Secondary roadways serve as connectors between primary roads and tertiary roads and typically connect primary roads to adjacent land use zones.  These roads are shown in orange on the visual analysis maps in Section 5.  Secondary roads accommodate moderate to slow traffic speeds with one moving lane in each direction.  On-street parking should be prohibited and left-turn lanes provided at intersections with primary roads.  Design characteristics include:

• Continuous through-traffic alignment between primary roads, either straight or curvilinear based upon the design speed topography and land pattern.

• Direct access to abutting property.

• A maximum of two moving traffic lanes in each direction, either undivided or a boulevard with planted median.

• On-street parking generally prohibited.

• Sidewalk separated from the road by a planting strip.

• Street lighting, signing, and planting that reflect the moderate-to-slow speed nature of traffic and the character of the land use area they are in.

• No grade greater than 10%.

Curbs, gutters, and sidewalks provided in all cantonment areas and other residential areas with densities greater than two dwelling units per acre.
