Landscape architect vs civil engineer: who designs the splash pad?
Quick answer
Both. The landscape architect leads the holistic design — site layout, theming, planting, sight lines, accessibility, and user experience. The civil engineer stamps the technical drawings — grading, drainage, structural slab, plumbing hydraulics, and electrical bonding. Both signatures are required on the construction documents.
Splash pad design is a collaborative effort between two licensed professionals. The landscape architect (RLA — Registered Landscape Architect) leads conceptual and schematic design: site selection within the park, layout of features and amenities, theming, planting design, sight lines from caregiver seating, accessibility approach paths, sun-path orientation, and integration with surrounding context. The civil engineer (PE — Professional Engineer) handles the technical engineering: grading and drainage, structural slab design, plumbing hydraulic calculations, electrical bonding and grounding, stormwater management, and code compliance. Both stamp the construction documents — the landscape architect on layout and architectural sheets, the engineer on civil, structural, MEP. On smaller projects (under $250K) one firm employs both disciplines under one roof. On flagship destination pads, multiple specialty firms collaborate (water-feature consultant, accessibility specialist, lighting designer). Always verify both stamps before issuing for permit.
