Within play areas, ramps connecting ground level play components and ramps connecting elevated play components shall comply with Section 11B-1008.2.5.
11B-1008.2.5.1 Ground level.
Ramp runs connecting ground level play components shall have a running slope not steeper than 1:16.
11B-1008.2.5.2 Elevated.
The rise for any ramp run connecting elevated play components shall be 12 inches (305 mm) maximum.
ETA Editor's Note
The above restrictions on ramp slope for ramps connecting ground level play components, and on ramp rise for ramps connecting elevated play components, are more stringent than the ramp slope and rise restrictions prescribed at 2013 CBC 11B-405.2 & 11B-405.6, and at 2010 ADAS 405.2 and 405.6.
11B-1008.2.5.3 Handrails.
Where required on ramps serving play components, the handrails shall comply with Section 11B-505 except as modified by Section 11B-1008.2.5.3.
Exceptions:
1. Handrails shall not be required on ramps located within ground level use zones.
2. Handrail extensions shall not be required.

Handrail gripping surfaces with a circular cross section shall have an outside diameter of 0.95 inch (24 mm) minimum and 1.55 inches (39 mm) maximum. Where the shape of the gripping surface is non-circular, the handrail shall provide an equivalent gripping surface.
11B-1008.2.5.3.2 Handrail height.
The top of handrail gripping surfaces shall be 20 inches (508 mm) minimum and 28 inches (711 mm) maximum above the ramp surface.
