ADA Roadway Cross Slope
ADA Roadway Cross Slope
(OP)
I have several roadways and parking lot ADA crossings on a project where the longitudinal slope of the drive surface exceeds 2%. Is it required to create a 2% bench with grade breaks at all of the ADA crossings or is the cross slope able to exceed 2% across the drive area if the sidewalk approaches and ramps maintain a maximum 2% grade? This will be extremely tedious and labor intensive to provide transitions at all locations so I hoping to avoid this if it is allowed.

The way I read this is if there are no yield or stop signs, the cross slope can be more than 2%. If a stop sign is put in, it must comply with 2% cross slope. Not sure if this is compliant with the Fair Housing Act.
R302.6 Cross Slope. Except as provided in R302.6.1 and R302.6.2, the cross slope of pedestrian access routes shall be 2 percent maximum.
Advisory R302.6 Cross Slope. The cross slope requirements in R302.6 apply to sidewalks and other pedestrian circulation paths, pedestrian street crossings and at-grade rail crossings, and pedestrian overpasses and underpasses and similar structures (see R302.2). The cross slope of the pedestrian access route is measured perpendicular to the direction of pedestrian travel. Cross slope requirements are contained in R304.5.3 for curb ramps and blended transitions, and in R407.3 for ramps.
R302.6.1 Pedestrian Street Crossings Without Yield or Stop Control. Where pedestrian access routes are contained within pedestrian street crossings without yield or stop control, the cross slope of the pedestrian access route shall be 5 percent maximum.
Advisory R302.6.1 Pedestrian Street Crossings Without Yield or Stop Control. Pedestrian street crossings without yield or stop control are crossings where there is no yield or stop sign, or where there is a traffic signal that is designed for the green phase. At pedestrian street crossings without yield or stop control, vehicles can proceed through the intersection without slowing or stopping. Where pedestrian access routes are contained within pedestrian street crossings with yield or stop control, the cross slope of the pedestrian access route must be 2 percent maximum (see R302.6). At pedestrian street crossings with yield or stop control, vehicles slow or stop before proceeding through the intersection.
