Does the sidewalk have a landing at the top of the curb ramp at least 36" in length and at least as wide as the curb ramp excluding the flared sides

Does the slope of the landing permit water to drain and not accumulate

If a landing does not exist, are there flared sides with a slope of no greater than 8.33%

Does the curb ramp have flared sides

If the sidewalk landing at the top of the curb ramp is at least 36", is the slope of the flared sides 10% or less

If the sidewalk landing at the top of the curb ramp is less than 36" wide, is the slope of the flared sides 8.33% or less

Does the detectable warning consist of a surface of truncated domes

Does the dome base measure .9" minimum / 1.4" maximum with a top diameter between 50% minimum and 65% maximum of the base diameter with a height of .2"

Does the curb ramp have a level area at least 48"long x 36"wide at the top of the curb ramp intersected by the crossings

Is the 48"x36" area oriented so that the 48" length is in the direction of the running slope of the curb ramp it serves
