Chaffey Joint Union High School District Facility Master Plan (FMP)

Download Masterplan

Chaffey Joint Union High School District has determined that a comprehensive strategic plan is essential to assess facilities at each high school and identifies the needed improvements utilizing the basic principles:

Quality Learning Environment

The Facilities Master Plan identifies the essential improvements to achieve a high quality environment for learning, and provides safety and security provisions that reflect caring and respect for each student and staff.


Each student is entitled to the same high quality education regardless of the school of attendance. Offering the basic amenities (as applicable) at each of the schools in an environment that stimulates the learning process is essential.

Grass Roots Involvement

Staff and students at each school have the greatest interest in the facility improvements to be made since they “live” in the environment for a substantial part of their educational life. Meeting their expressed needs is essential to the success of the implementation of the FMP.

Fiscal Responsibility

Each school has a vast list of facility needs that far exceed the financial resources available to the District now and in the future. The District must maintain the public’s trust by prioritizing the identified needs and prudently, efficiently, and equitably utilizing its financial resources to maintain the long term viability of the District’s limited resources.


The District is engaging in an open process whereby all staff, students, and community have an opportunity to provide input to the facility needs. The District encourages input from diverse viewpoints and entertains differing opinions as it implements the FMP.


The implementation of the FMP will be highly scrutinized by the Board of Trustees and District leaders, who will provide oversight to the process and monitor the District’s use of funds as they become available.
