Sidewalk Design
Design Summary
Preferred Design
While the width of the curb, furnishings and frontage zones may
be adjusted to reflect the needs of the site, the through zone
should always be at least 5’ wide in all locations. Wider
sidewalks are appropriate in areas with high levels of pedestrian
traffic.
Discussion
Sidewalks are comprised of four zones: curb, furnishings,
through pedestrian and frontage. The curb zone abuts the street
and provides a buffer between the sidewalk and the street. The
furnishings zone lies between the through zone and the curb
zone and provides a location for street furniture and other
public amenities such as trash receptacles, bicycle racks,
lighting, news racks, and water fountains. The through
pedestrian zone is the sidewalk space for walking and is located
between the furnishings zone and the frontage zone. The
through pedestrian zone is the widest zone and should be clear
of obstructions at all times. Finally, the frontage zone provides a
transition between the building or property line and the
through zone. The frontage zone may feature furniture and act
as an outdoor extension of restaurants or cafés.
Guidance
Sidewalks should be
• located on both sides of the street;
• constructed of durable, slip-resistant materials, like Portland cement;
• clearly delineated from zone to zone—furniture should not be placed in the through zone, etc.;
• kept clear of obstructions at all times in the through passage zone.
General maintenance should be conducted regularly to repair cracks and gaps and remove debris, which can present safety hazards
to pedestrians.
Tree Planting in Planting Zone
Trees surrounded in paving require special attention in order to reduce future paving destruction and increase longevity of the trees.
Canopy trees (as shown in this graphic) require an additional treatment in order to provide long term sustainability. The entire length
and width of the “Planting Zone” should receive a 2’ depth of Structural ‘CU-SOIL’ as the planting medium for the trees. The CU-SOIL
mix should extend from the curb back to the property line in continuously paved areas. Automatic irrigation and a 5’ X 5’ tree grate are
to be included as well in this design layout.
The exception to the use of Structural ‘CU-SOIL’ would be where palm trees are used. Palm trees do not require Structural Soil. 5’ X 5’
tree grates are required in areas surrounded by paving. An automatic irrigation system is also required.
