A master plan for a 3,700 acre new community in the secluded hills east of Cupertino presently used as a cement quarry. The plan is for reuse of the land after the quarrying operations have been completed. The aim was to develop a completely self-contained, mixed-use community which would minimize external traffic. The plan, aimed at providing for a mix of income levels, includes residential, commercial, recreational facilities and professional opportunities for future residents. A major consideration was to provide affordable housing for local working people. Attention was also paid to ecologically-sensitive ravines which have been incorporated as open space spines throughout the development.
