Flared sides The sloped transition zones located on the lateral sides of a curb ramp, designed to prevent pedestrians from tripping as they cross the ramp sideways.
Also referred to as side flares, these angled sections connect the sloped center of a curb ramp to the adjacent flat sidewalk flags. In NYC, if the sidewalk landing at the top of the ramp is narrower than 4 feet, the flare sides must be sloped at a gentle ratio of 1:10 or flatter. Incorporating properly constructed flared sides is a critical design step that prevents sudden vertical drop-offs, ensuring a smooth transition for all foot traffic.
Frequently Asked Questions About Flared sides
What are flared sides on a curb ramp?
The sloped transition areas on each side of the ramp that connect it to the adjacent sidewalk, preventing a vertical drop-off.
Why are they needed?
Pedestrians frequently cross a ramp sideways. Without flares, the ramp edge becomes an abrupt step and a fall hazard.
What slope applies to flares?
Where the top landing is narrow, flares must be gentler, commonly 1:10 or flatter. The applicable standard depends on the landing width.
Are flares always required?
No. Where a ramp is bounded by a wall, planting or other non-walkable surface, returned curbs may be used instead.
