Maximum cross-slope for non-ADA walkway
Maximum cross-slope for non-ADA walkway
(OP)
Does anyone know if there is a maximum cross-slope for non-ada walkways? I have a housewalk (3' wide) going from the front entry of a house to the house driveway(perpendicular to the driveway). The idea was to warp the sidewalk where it met the driveway. The driveway has a slope of 15% so the cross slope of the sidewalk where it meets the driveway would be 15%. I am wondering if the cross-slope of the walkway would exceed any building codes. I am only finding ADA cross slope minimums. Does someone know of any codes that would specify the cross slope for Non-ADA walkways?
Thanks,
Thanks,

I am not aware of any local or national codes that address your issue so it may come down to an "annoyance" issue for the users. What effect will it have when you're ready to sell your house?

Building Codes are different everywhere, but I would guess that if the 15% driveway is acceptable, the sidewalk transition would also be ok. Come to think of it, I doubt there's any specific language in the building code that even says you need a sidewalk from the driveway to the front door.

Warp it from 15% back to 2% in 5' feet or so. Match the longitudinal grade of the sidewalk to the high side of the driveway and warp down so you don't create a sump for water to collect.

If you transition/warp the difference at a 6% rate of change it would take 6.5 feet to make up for the 0.39'.
