Tactile Warning Strip at Van Accessible Stall

[ijosifek]

Are Tactile Warning Strips required at all ramps regardless of purpose? The specific situation is a ramp coming from a building door to a van accessible loading area next to the parking stall. The ADA accessible route is only building to parking stall. I am guessing it is required but couldn't find the code that shows this specifically. The code focuses on where ramps are directed into vehicle traffic areas.

Is this the applicable code?

They're typically only required at curb ramps and blended transitions, platform edges, street intersections, or whenever a accessible route enters a vehicle way. Here's a link to the technical requirements for detectable warning for compliance with PROWAG. Regular ramps (not curb ramps) don't always need a detectable warning surface.

The link you provided seems to be to a draft version of the guidelines, not the final guidelines. The applicable code is whatever's been adopted by the jurisdiction you're in and the 2010 ADAS and/or PROWAG.

For example, in California, we adopt and heavily amend the 2010 ADAS into our Building Code as Chapter 11B. We added a section to ADAS (11B-247) that specifies where detectable warnings are required. Your state building code may have something similar. For reference, here's California's requirements for where they're required, which go beyond PROWAG and ADAS.

This is a project in Idaho. I guess I need to determine the correct term for this case. Maybe a pedestrian ramp and not a curb ramp. It is to a vehicular area (parking stall/loading area) but not into a vehicle travel way. Thanks for the help.

Any chance you can post a picture or link to something similar? If it leads a parking space / access aisle / loading zone, then it probably needs detectable warning.

For what I’m about to say, you need to make sure that you do indeed have a ramp, meaning a sloped walking surface steeper than 1:20.

When that is the case, you want to be careful as to how you treat this, as a “pedestrian ramp” (just referred to as a “ramp” in A117.1) or a “curb ramp” because the requirements are different. For example, ramps require edge protection and may require a handrail if the rise if greater than 6”; curb ramps require neither. Landing dimensions are also different. Sounds to me like you have and want a curb ramp.

Looks like a parallel curb ramp. Yes, detectable warning is almost certainly required here.

Edit: Even if it wasn't a ramp (in which case this would be a blended transition), detectable warning would be required.
