Splash zone perimeter
Definition
The marked edge of the active splash pad — typically a curb, color change in surfacing, or low fence — defining where wet play is permitted and where parents and street shoes are expected to stay dry.
The splash zone perimeter is what keeps strollers, dogs, picnic blankets, and street-shoe foot traffic out of the wet play area. State codes increasingly require a clearly defined perimeter for both safety and chemistry reasons — every dry-shoe step into the wet zone introduces contaminants the recirc system has to filter out.
Perimeters are usually a 6-inch curb, a contrasting tile band, or a knee-high decorative fence. Some pads use bollards every 8 feet with chains or rope between. ADA-compliant pads include at least one curb-cut entry that meets reach and surface-transition rules.
