Children living in the area attend Portola Hills Elementary.
Built in the mid-1990s, Portola Hills Elementary was subject to litigation between the SVUSD school district and the developer concerning land movement at the school site. The litigation was dismissed due to procedural issues regarding the statute of limitations. In 2004, three buildings were vacated for safety reasons due to damage potentially caused by the land movement and the students relocated in portable/temporary classrooms until a permanent solution could be made. As of mid-2008, the developer (USA Portola Center, LLC) entered into a School Facilities Funding and Mitigation Agreement with the school district for development originally known as "Portola Hills South" and now known as "Portola Center." That agreement requires the developer to pay the district $2,900,000 (in addition to any other new development mitigation fees), solely for use in the repair of the school.[2] As of June 2008, the district is moving forward with plans to repair two buildings and potentially demolish/rebuild the third provided approval is obtained from the Department of State Architecture.
