ADA Curb Ramps

Is the curb ramp at least 36" wide [406.1, 405.5]

Does the curb ramp have a running slope of 8.33% or less [406.1, 405.2]

Does the curb ramp have a cross slope of 2% or less [406.1, 405.3]

Does the curb ramp have a gutter slope of 5% or less [406.2]

Are transitions on and off the curb ramp flush and free of abrupt level changes [405.4, 302]

Is the curb ramp free from blockage by legally parked cars [406.5]

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 [406.4]

Does the slope of the landing permit water to drain and not accumulate [405.10]

If a landing does not exist, are there flared sides with a slope of no greater than 8.33% [406.4]

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 [406.3]

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 [406.4]

If no flared sides, is there an obstruction or grass on each side of the curb ramp that discourages pedestrians from traveling across the ramp [406.3]

Does the curb ramp have detectable warnings (2010 ADA standards do not require detectible warnings on curb ramps. However, the Access Board is developing new guidelines that will address access to public rights-of-way, including detectible warnings at curb ramps.) [705]

Does the detectable warning surface contrast visually with adjacent walking surfaces either light on dark or dark on light [705.1.3]

Does the detectable warning extend across the entire width of the curb ramp (excluding flared sides) [705.2]

Does the detectable warning extend either the full depth of the curb ramp or at least 24" measured from the back of the curb on the ramp surface [705.2]

Does the detectable warning consist of a surface of truncated domes [705.1]

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" [705.1.1]

Do the domes have a center to center spacing between 1.6" and 2.4" with a base to base spacing of .65" minimum [705.1.2]

If the curb ramp is built up to the curb, is it at least 36" wide, with a top landing at least 36" deep and outside the path of anywhere cars are allowed to drive [406.5, 406.4]

If the curb ramp has flared sides, is the slope no greater than 5% [406.3]

If curb ramp is corner type, is the bottom of the landing at least 48" long and contained in the crosswalk [406.6]

Is the ramp of the curb ramp contained in markings [406.6]

If the curb ramp has flared sides, is there a segment of curb that extends at least 24" long on each side of the curb ramp and within the marked crossing [406.6]

If a sidewalk goes through a raised island, are there curb ramps [406.7]

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 [406.7]

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 [406.7]

Is the curb ramp a parallel or double curb ramp with a common bottom landing

is the ramp run slope no greater than 8.33% [405.2]

is the ramp cross slope no greater than 2% [405.3]

is the bottom landing no less than 36" long and 36" wide [406.4]
