Common Sources of Confusion in the ADA and ABA Standards

2:30 pm EST December 06, 2018   |   Organized by: Great Lakes ADA Center


Date/Time: Thursday, December 6, 2018 at 2:30 PM Eastern Time Zone

Location: Webinar

Description: Certain provisions in the ADA and ABA Accessibility Standards are prone to misinterpretation and generate many of the technical inquiries the Access Board receives. This webinar will review and clarify these “hot spots” in the standards. Reviewers will untangle common sources of confusion, including those concerning application of the standards in new construction and alterations, employee work areas, toilet rooms, signs, detectable warnings, and other topics.

Questions for presenters:

  • If you are also covering PROWAG I would like to better understand the allowance for 5% max cross slope at intersections that are not controlled by a stop or yield (signalized intersections). Please provide specific examples of intersections that would require 2% cross slope max or 5% max and why.

  • As a designer for state DOT I have received a number of comments from people who are blind and their trainers regarding the layout of the detectable warning. They would prefer detectable warning units to be laid out to assist with orientation to the crossing. However current guidance from the Access Board is that they are NOT intended for way finding but only to alter the pedestrian that they are leaving the pedestrian zone and entering a vehicular or hazard zone. Is further guidance needed to reinforce their purpose? or is an alteration in their use warranted?
