Current through Register 1525, July 5, 2024
Curb cuts
shall occur wherever an
accessible route
crosses a curb and at the following locations:
21.2.1
Curb cuts
are required at each corner of each intersection, located within the crosswalk and/or the pedestrian path of travel.
Curb cuts
shall be perpendicular to the curb at street crossings and each shall have a
level

Exception: Where pedestrian right-of-way established width will not accommodate a perpendicular
curb cut
and landing, a parallel public
sidewalk curb cut
with a
level
landing at its bottom shall be provided instead of a perpendicular
curb cut

curb cut
or a parallel
curb cut
with a level landing, an apex curb cut is allowed. Site constraints include the following:
a. Driver or pedestrian line of sight to or from the front of the level landing on the ramp is impaired, preventing safe observation of crosswalks or approaching traffic at the intersection by a significant immovable or unalterable streets cape feature such as a building, structure or historic element, etc.
b. Stop line is beyond the allowed limit as stated in the Manual on Uniform Traffic Control Devices.
c. Vaults containing electrical, telecommunications, etc. that are under or on the existing sidewalk.
