In 1975, the community bid a sad farewell to historic Main Hall at the East Campus when it was demolished because it did not meet earthquake and education codes. In 1978, the district celebrated the opening of the replacement administration and library building. It was joined by a new auditorium in 1981 (later named the Stratton L. Tarvin Presentation Center for the Performing Arts in honor of a long-time administrator). In 1980, Hanford Adult School was built on Campus Drive. In 1994, Earl F. Johnson High School was moved a few blocks south on Douty Street to a former elementary school. A $1 million modernization in 2002 expanded classroom space there. In 1997, the district began its biggest construction project in many years: A $18 million local bond and matching state grants funded the construction of classrooms, labs, a library, a performing arts building, an event center and more to transform West Campus into Hanford West High, an independent school. The 2001-2002 school year marked an important milestone for the 100+ year old district: Four independent high school graduations. Hanford West High's first graduating class numbered 291. Hanford High graduated 342; Earl F. Johnson had 21 graduates and Hanford Adult school gave out 41 high school diplomas. On August 13, 2009, a third comprehensive, state-of-the-art high school called Sierra Pacific High School opened with 217 freshmen. Phase two of Sierra Pacific High will include additional buildings, including an administration building, a second academic building, a wrestling room, a pool and aquatics center, maintenance facilities, and a library and media center according to student growth and the need. Sierra Pacific High School was built because the two existing comprehensive high schools were over their enrollment capacities. Hanford High School and Hanford West High School are each built to hold about 1,700 students, but the student population at each was approaching 2,000 students. The Board of the Hanford Joint Union High School believes it is in the best interest of all students to keep high school enrollment at or below 1,700 students each. Studies have shown that this is a size that is big enough to allow for a variety of quality academic and extra-curricular activities, but small enough to allow for the personal interactions that help drive student success. No plans have been made to build any more high schools in the near future in Hanford, but as the city continues
