Figure 12(a)
Sides of Curb Ramps
Flared Sides

Note: If X is less than 48 inches, then the slope of the flared side shall not exceed 1:12.

This figure shows a typical curb ramp, cut into a walkway perpendicular to the curb face, with flared sides having a maximum slope of 1:10. The landing at the top, measured from the top of the ramp to the edge of the walkway or closest obstruction is denoted as "x". If x, the landing depth at the top of a curb ramp, is less than 48 inches, then the slope of the flared side shall not exceed 1:12.
