Exterior Routes & Surfaces

Thursday, May 4, 2023
2:30 PM - 4:00 PM Eastern Time Zone


Access to buildings begins with an accessible route and ground surfaces to ensure people who use mobility devices and canes can move from site arrival, frequently outdoors, to the entrance.

This session will address the requirements for exterior routes and surfaces to ensure everyone has access within all spaces on a site. Access Board Accessibility Specialists will review the differences between accessible routes for building sites, outdoor recreation areas, trails, and beaches. Additionally, the presenters will share information on the concepts of stable, firm, and slip resistant surfaces in the outdoor environment. Playground surfaces will also be covered.

Video remote interpreting and real-time captioning will be provided in this webinar.

Questions can be submitted in advance of the session or may be posed during the live webinar. Participants can also earn continuing education credits.

Questions for presenters:

1 If a driveway to a drive aisle is bordered by a walkway at the same level, can bollards be used in lieu of raised sidewalks or truncated domes as an edge identifier? Can a driveway be of DG with a stabilized and adjacent to a turf block walkway (this to allow for permeability? Can turf blocks be used for accessible parking and if so how do you stripe them?
2 What % of slope to a depression in an access aisle not exceeding 1/2" in height would cause a wheelchair to begin to roll? What is the maximum/minimum distance between points of deviation not exceeding 1/2" in height in an access aisle if in general it does not exceed 2% slopes??
3 When do pedestrian exit paths from a building to a public way need to be constructed as accessible routes?
4 If a road has an 8% slope and there is a pull-out/drop off point to access a small building (single user restroom at public park in this case), does the pull out space have to be level in both directions, or can it match the slope of the road?
5 What about trying to get into the glass double doors of a USPS post office? Law not updated since 1992 ABA. Lots of mobility devices since then—like power wheelchairs and the 3-wheel scooters since then (made) and in use. Try working a chair and opening the doors. They only have to weight 5 pounds. Then there is a single glass inner lobby door too. Need automatic door openers (been around over 100 years) supermarkets got them in the 1950’s, as loosing business with people buying less. Unfair., Unjust and Unequal for persons with mobility issues Civil Rights. Create jobs, price come down and states and counties would follow suit. Then businesses. THEN there would be access for everybody. Do Something. Thank you. Libras Libertas, Donna Malahni Jackson.
6 Have only an iPhone—no computer. Plus doctor appointment that day. Please send me how this will be addressed. Donna
7 Can you go over when when edging or compliant railing is needed over a constructed walkway over wetlands or water is needed on trail/walkway? And what is the required height for the edging?
8 Are sidewalks located within a pubic right-of-way considered an accessible route and therefore must comply with ADA and be firm stable and slip-resistant?
9 Looking for information and direction on what type of improvements can be done to existing equestrian, and shared trail systems on public and private lands to increase accessibility for all. Are there recommendations for seeking funding assistance to improve the accessibility of existing trails?
10 What makes trails more ADA accessible? Any opinions on improvements to an existing trail verses creating a new trail all together in the aspect of cost and accessibility?
11 As we observe significant differences in round pebbled surfaces and compacted, smaller decomposed granite surfaces' 1)firmness and 2) stability, what test can be used onsite for the 3) slip-resistance, and what chemical stabilizers are currently providing sufficient slip-resistance?
12 There is a redesign of an exterior area near an accessible, the goal is to provide a nature loop for individuals to walk. The nature loop does not meet Trail standards, therefore, it's not a trail, what would be the appropriate code design standards?, the nature loop will have natural materials, but will be firm and stable.
