The allowed slope for a ramp according ADA 1.5-3%. The recommended slope for drainage is 3-6%. Better hope you're really fucking precise. Oh, your road itself

Oh, your road itself is at a slope greater than 3%? Oops, you can't legally do it!
It's okay to have standards. It's not okay if they're bullshit.
- jaclaz 4y agoYou sure? ADA ramp max slope should be 1:12, i.e. 8.33% which is (IMHO) reasonable. https://www.ada-compliance.com/ada-compliance/ada-ramp https://www.ada-compliance.com/ada-compliance/ada-ramp
- Loughla 4y agoDon't make things up. Recommended slope for drainage on concrete and asphalt is .25-.5:12, or 1/4" to 1/2" over 1' of length. Recommended slope for wheelchair ramps are 1-1.5:12, or 1" to 1.5" over 1' of length.
