The property at 1150 Eastern Avenue has served the affluent Arden Park neighborhood as an educational center since the early 1960's. The site possesses a rare and valuable Conditional Use Permit (CUP) to operate a school, which runs with the land. Originally, the campus was constructed on 12.77 acres as an elementary school, serving the neighborhood in that capacity until it transitioned into an adult education facility. In 1984, the property was declared surplus property by the San Juan Unified School District. The Subject Property was sold to River Oaks Center for Children, Inc. (formerly Re-Ed West) for the operation of a non-profit private school. The balance of the original school site was sold to Mission Oaks Park and Recreation District for a community park and the home of the Eastern Little League, which remains in operation today.

Local School Districts send students to the schools and pay a tuition for their specialized education. School districts typically place a student in a "non-public" school when they can no longer meet their unique individual educational needs or when students become too complex or disruptive or a danger to themselves or others if they remain in their neighborhood schools.
