Type 1A curb ramps ramp the sidewalk down to a level landing. This curb ramp is commonly installed on narrow sidewalks. Truncated domes may be installed radial as shown or in a linear formation. See RC-67M for more details on truncated dome installations.

Level landings are required where pedestrians perform turning maneuvers (2.00% maximum longitudinal and cross slope). Slopes indicated are maximum slopes and cannot be exceeded. Diagonal curb ramps are not preferred. Any pedestrian facility that is “altered” must meet the latest standards.
