ADA Roadway Cross Slope 1

green70, see this thread: ADA pedestrian crossing - cross slope over existing road exceeds 2%

My glass has a v/c ratio of 0.5

Maybe the tyranny of Murphy is the penalty for hubris. -

Thanks for the link. I did see that thread but was not clear on how that pertained to a new development. I am currently working on a very tight multi-family plan with a lot of fall across the site. Was hoping someone could help clear up for me if the 2% cross slope was required at all intersections. Can I get away without 3-4% at mid-block ramps? Another option I have considered is eliminating some of the accessible route locations. I assume this would require removing sidewalk entirely. My understanding is that if the sidewalk / crossing is there, it must be accessible. Planning is definitely going to push back on removing the walk.

Below is from page 75 of the US Proposed Accessibility Guidelines for Pedestrian Facilities in the Public ROW, July 26, 2011

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.

The cross slopes and slope only apply to the accessible route in ADA. Further, there are two other criteria that have to be met....is it economically feasible and can there be equivalent facilitation otherwise.
