1. Accessible Routes
A facility has an interior walking surface that is 42 inches wide
throughout its length. At one location, the route narrows to 32
inches for a 30-inch-long segment. Which statement is most
accurate under the 2010 ADA Standards?
A. The 32-inch segment is permitted because the overall route
is wider than 36 inches.
B. The 32-inch segment is permitted if a second accessible
route is available.
C. The 32-inch segment is not permitted because a reduced
width of 32 inches may extend only 24 inches maximum.
D. The 32-inch segment is permitted whenever it occurs in an
existing facility.
The ADA Standards generally require accessible walking
surfaces to have a clear width of at least 36 inches. A reduction
to 32 inches is permitted only for a length of 24 inches
maximum, with qualifying wider segments separating reduced-
,width portions. A 30-inch-long restriction therefore exceeds the
permitted length.
2. Running Slope
A level interior corridor forms part of an accessible route. Its
running slope is measured at 1:18. Which conclusion is correct?
A. The slope complies because it is less than 1:12.
B. The slope complies because interior routes may be steeper
than ramps.
C. The slope does not comply as a walking surface because
walking surfaces are limited to a running slope of 1:20
maximum, unless treated as a ramp where the applicable
requirements are met.
D. The slope automatically qualifies as a curb ramp.
Walking surfaces that are part of an accessible route generally
have a maximum running slope of 1:20. A steeper slope is
addressed under the ramp provisions when the element
qualifies as a ramp. Simply describing a sloped walking surface
as a corridor does not eliminate the applicable slope
requirements.
3. Cross Slope
,What is the maximum cross slope generally permitted for an
accessible walking surface?
A. 1:20
B. 1:48
C. 1:50
D. 1:64
The 2010 ADA Standards limit the cross slope of accessible
walking surfaces to 1:48. This requirement is distinct from the
1:20 maximum running slope generally applicable to walking
surfaces.
4. Ramp Rise
A newly constructed ramp has a total vertical rise of 36 inches.
No intermediate landing is provided. Which statement is
correct?
A. The ramp complies because there is no maximum rise for a
single ramp run.
B. The ramp complies if its running slope is exactly 1:12.
C. The ramp complies if handrails are installed.
D. The ramp does not comply because a single ramp run may
rise no more than 30 inches.
, Under the ADA Standards, a single ramp run is limited to a
maximum rise of 30 inches. A 36-inch rise therefore requires the
ramp to be divided into multiple runs with appropriate landings.
5. Ramp Slope
Which running slope is generally the maximum permitted for an
accessible ramp?
A. 1:10
B. 1:12
C. 1:16
D. 1:20
The maximum running slope for a ramp is generally 1:12. A
ramp rising 1 inch for every 12 inches of horizontal run
therefore represents the steepest generally permitted slope
under the ADA Standards.
6. Ramp Landings
A ramp changes direction at an intermediate landing. What is
the primary accessibility concern with the landing?
A. It must always contain a detectable warning.
B. It must be at least 48 inches long regardless of ramp
configuration.
