One of the key components of a walkable neighborhood is the sidewalk—the roadway for pedestrians. Characteristics of good sidewalks include:
- They are continuous—there are no gaps in the sidewalk network.
- They are installed on both sides of a street; while a sidewalk on one side of the street is certainly better than no sidewalk at all, this does not mean that a sidewalk should not exist on both sides of the street.
- They are separated from moving traffic. A planting strip is a common buffer, and if wide enough can include street trees. Parked cars or on-street bike lanes also provide separation of pedestrians from traffic.
- They are wide enough to comfortably accommodate at least two adults walking side by side, and are clear of obstructions both horizontally and vertically; this includes overgrowth, parked vehicles, and garbage or recycle containers.
- They are well maintained and free of cracks or lifted sections that could become tripping hazards and barriers to people in wheelchairs.
