NOTES:
| |||||||||
1
|
Bike lanes should be made wider than minimum widths wherever
possible; if sufficient space exists, buffered bike lanes should be
provided. In C4 and C5 contexts, separated bike lanes are preferred.
Separated bike lanes are vertically separated from moving traffic
(placed above the curb) or horizontally separated by a buffer or planting
strip.
| ||||||||
2
|
An allee of trees are planted in a straight, evenly spaced row
alongside travel lanes. Trees may be planted closer than the typical
spacing, where desired.
| ||||||||
3
|
All dimensions are measured to face-of-curb.
| ||||||||
4
|
A one-way street may have one lane, which may exceed the widths
in this table with approval of the City Engineer.
