What is a sight-line study for a splash pad?
Quick answer
A sight-line study analyzes whether caregivers seated around the splash pad have unobstructed views of all play areas. Designers map view cones from every seating location and verify no shade structures, vegetation, or features block visibility of children. Critical for safety design.
Sight-line studies are a core safety-design exercise for splash pads. The landscape architect maps view cones from every potential caregiver location — benches, picnic tables, shade-structure seating, lawn areas — and overlays them on the play surface. Each child play zone must be visible from at least 60% of caregiver seating, and entry/exit paths must be visible from primary seating. Common sight-line killers include: tall theming features placed in the middle of the pad, shade structure columns blocking views, dense planting at adult eye height (3.5-5 feet), play features that visually isolate children behind their cores, and sloped grading that drops parts of the pad below sightline. The study uses 3D modeling software (Rhino, SketchUp, Lumion) and produces heat maps showing visibility coverage. Designers iterate until coverage is 80%+. Strong sight lines reduce the parental supervision burden, prevent stranger-danger blind spots, and support drowning-prevention layered safety. Specialized accessibility sight-line studies also verify wheelchair-seated caregivers can see the whole pad.
