With increased concern in recent years for the quality of our cultural and physical environment, there has been a corresponding increase in the need for information on standards used for planning playgrounds and parks, sports facilities, and outdoor areas for camping and hiking. Standards for various types of outdoor recreational facilities as used or proposed by recreation planners, agencies, and organizations are presented in this publication with emphasis on space requirements. Such standards may be used as guidelines to improve inadequate facilities or to develop new ones. A bibliography of source materials is included so the user can refer to the conditions under which relative requirements were developed. (JH)
