This report, funded under Title III of ESEA, describes the Berkeley Unified School District's search for a permanent solution to the problem of maintaining racial heterogeneity along with educational quality. Of the alternatives available, the educational park concept was found to be most promising. Early sections of the report deal exclusively with the planning processes relating to the dissolution of elementary school segregation in Berkeley. The remaining portions describe the longrange planning of an educational park complex and a prototype model of a middle school, grades 4-8, as part of that complex. Cost associated with the various innovations are carefully analyzed. (TT)
