This publication presents principles of universal playgrounds, designed to maximize accessibility for all children, with and without disabilities. First, the rationale for the universal playground is given including the importance of play and the value of integration. Next current guidelines for playground design are discussed including safety, accessibility, developmental issues, social/emotional development, intellectual development, sensory development, perceptual-motor development, physical development, and age factors. Playground adaptations to improve accessibility are considered for site development, parking and curbs, walkways, and surface treatments. Playground layout is then considered in some detail including standards for equipment clearance, traffic patterns, practical aesthetics, maintenance, and possible equipment. A table lists 36 equipment items, their goals and benefits, description, and possible modifications. Source information (addresses and telephone numbers) for 56 manufacturers and distributors of playground equipment are provided, as are 16 sources of playground surface materials. Sample layouts, a planning survey form, a universal playground action plan checklist, and a list of 10 additional resources complete the publication. (DB)
