This paper will explore the relationship of open space to the design of new communities. Past approaches to planning new communities with open space in mind will be examined including new urbanist planning efforts. Case studies of past planned communities that have utilized open space as central organizing element will be examined including Radburn New Jersey, Greenbelt Maryland, and Village Homes in California. Past research on the value of open spaces to the community and public life of these developments will be explored. The paper will conclude with a framework for developing open space as a central organizing feature in future new communities.
