Transition surface
Definition
The graded surface — often a curb-cut ramp or flush concrete band — that connects an accessible path to the splash pad play zone without a step or barrier.
Transition surfaces are an ADA-compliance requirement for new splash pad builds. The grade change must be 1:20 or gentler, the surface must be firm and stable when wet, and the path width must accommodate a wheelchair turn radius.
Well-designed transitions are nearly invisible — a single concrete pour blending sidewalk to pad. Poorly designed transitions create the trip hazards parents notice immediately.
