Survey Form 4: Curb Ramps

Section	Item	Technical Requirements	Comments	Yes	No
4.7.1	Curb Ramp - Location:	Is there a curb ramp wherever an accessible route crosses a curb?
4.7.2 4.8.2	Slope:	Is the slope of the curb ramp 1:12 or less in new construction?
4.7.2	Transition:	Is the transition from the curb ramp to the walkway and to the road or gutter flush and free of abrupt changes?
	Counter Slope:	Are the running slopes of the road, gutter or accessible route adjoining the ramp no greater than 1:20?
4.7.3	Width:	Is the width of the curb ramp, not including the flared sides, at least 36 inches?
4.7.4 4.5.1	Surface:	Is the surface of the curb ramp stable, firm and slip-resistant?
4.7.5	Side Flares:	If the curb ramp is located where pedestrians must walk across it or where it is not protected by handrails or guard rails, does it have flared sides?
	Side Flare Slope	Do these flared sides have a slope of 1:10 or less?
		Where the space at the top of the ramp is less than 48 inches and wheelchair users must use the side flares for access, do the flared sides have a slope of 1:12 or less? (See Figure 12(a))
4.7.5	Returned Curbs:	If sharp return curb cuts are present, is pedestrian cross traffic prohibited by walls, guardrails, shrubbery, or other elements? (See Figure 12(b))
4.7.6 4.6.3	Built-up Curb Ramps:	Are built-up curb ramps located so that they do not project into vehicular traffic lanes or parking access aisles?
4.7.7	Detectable Warning:	Does the curb ramp have a detectable warning?
4.29.2	Domes:	Does the detectable warning consist of raised truncated domes?
	Size and Spacing:	Are the truncated domes 0.9 inches in diameter and 0.2 inches in height with a center-to-center spacing of 2.35 inches? All measurements are nominal. (See Figures below)
	Visual Contrast:	Does the detectable warning contrast visually with adjoining surfaces (light-on-dark or dark-on-light)? Is the material used to provide contrast an integral part of the walking surface?
4.7.8	Parked Vehicles:	Are curb ramps located or protected so that they will not be obstructed by parked vehicles?
4.7.9	Curb Ramps at Crosswalks:	Are curb ramps at crosswalks wholly contained within the crosswalk lines, except for the flared sides?
4.7.10	Diagonal Curb Ramps:	If diagonal (or corner-type) curb ramps have returned curbs or other well-defined edges, are these edges parallel to the direction of the pedestrian traffic flow?
	Bottom of Diagonal:	Is there at least 48 inches clear space within the crosswalk lines at the bottom of a diagonal curb ramp?
	Straight Curb:	If the diagonal curb ramp has flared sides, is there at least a 24 inch segment of straight curb located on each side of the curb ramp within the crosswalk lines?
4.7.11	Island:	Where an accessible pathway crosses an island, is the island cut through at street level? OR Are there curb ramps on both sides and a level area at least 48 inches long between them? (With a 6 inch high curb, the island will be at least 16 feet wide.)
