304 1 Public Sidewalk Curb Ramps Typical Placement Of

GENERAL NOTES Public sidewalk curb ramps shall be constructed in the public right of way at locations that will provide 1. continuous unobstructed pedestrian circulation paths to pedestrian areas, elements and facilities in the public right of way and to accessible pedestrian routes on adjacent sites. Curbed facilities with sidewalks and those without sidewalks are to have curb ramps constructed at all street intersections and at turnouts that have curbed returns. Partial curb returns shall extend to the limit prescribed by Index No. 515 to accommodate curb ramps. Ramps constructed at locations without sidewalks shall have a landing constructed at the top of each ramp, see Sheet 5. Varies The location and orientation of curb ramps shall be as shown in the plans. 2. (5' Min.) Curb ramp running slopes at unrestrained sites shall not be steeper than 1:12 and cross slope shall be 3. 0.02 or flatter. Transition slopes shall not be steeper than 1:12. Drop When altering existing pedestrian facilities where existing site development precludes the accommodation ng k of a ramp slope of 1:12, a running slope between 1:12 and 1:10 is permitted for a rise of 6" maximum l i t a 1:12 s e w and a running slope of between 1:10 and 1:8 is permitted for a rise of 3" maximum. Where compliance i 02 x e . op 0 d E l with the requirements for cross slope cannot be fully met, the minimum feasible cross slope shall be i S S provided. p p Ramp running slope is not required to exceed 8' in length, except at sites where the plans specify a i Trans m r . a t greater length. R S 02 . 0 y 02 . it 0 l If a curb ramp is located where pedestrians must walk across the ramp, then the walk shall have ti 4. U transition slopes to the ramp; the maximum slope of the transitions shall be 1:12. Ramps with curb returns may be used at locations where other improvements provide guidance away from that portion of curb perpendicular to the sidewalk; improvements for guidance are not required at curb ramps for linear pedestrian traffic. Curb ramp detectable warning surfaces shall extend the full width of the ramp and 24" deep. Detectable 5. warning surfaces shall be constructed in accordance with Specification 527. See Sheet 6 for detectable warning layouts. Transition slopes are not to have detectable warnings. Detectable warnings are required on sidewalks at intersecting roads, streets and railroads. For requirements for detectable Where Curb Ramps Are Constructed In Existing Sidewalks warnings on sidewalks at intersecting driveways, see Index 310.
