2022 California Standards for Accessible Design Guide (effective January 1, 2023)
11B-403.7 Continuous gradient.
All walks with continuous gradients shall have resting areas, 60 inches (1524 mm) in length, at intervals of 400 feet (121,920 mm) maximum. The resting area shall be at least as wide as the walk. The slope of the resting area in all directions shall be 1:48 maximum.
ETA Editor's Note
CBC requirement 11B-403.7 is not present in the 2010 ADA Standards. Therefore, CBC requirements related to continuous gradients are more stringent.
