LearnBoost welcomes Piner High
Piner High School was built in 1966 in semi-rural Sonoma County on Fulton Road near Piner Road just west of Santa Rosa. Initially it was surrounded by orchards and pastures. By 1975 the City of Santa Rosa expanded to the back fence of the school. In the late 1980s further expansion included more housing on two sides and Youth Community Park (including an award winning skate park) across the street.
Piner High School was opened with 9th, 10th, and 11th grades in the fall of 1966. The next year it became a four year high school, with the class of 1968 being the first graduating class of the school history. The class of 1975 was the last of the four year classes until 1996, when Piner was reestablished as a four year high school to alleviate overcrowding of local middle schools.
The central quad was completed for the fall of 1970, and the class of 1974 was the first class to enjoy crossing campus without going through the mud during rainy winters.
Piner High School was named for a family of squatters who occupied nearby lands for several decades in the late 1800s. Many locations in the area northwest of Santa Rosa took on this name, as the Piner family became quite notorious and certainly the most recognizable name in the area.
Piner High School is unusually designed in that there are no indoor hallways and student lockers are located on the outside of buildings, secured during non-school hours with hurricane fencing. Each building was constructed with wide overhangs and interconnecting covered walkways between buildings to shelter students from the weather.
All original classroom buildings are constructed with all classrooms accessed directly from the outdoors with main entrances on the outside of the square and secondary entrances through an atrium in the center of the building. Each classroom building was designated for a group of related academics, such as the Language Arts building, the science and math building, the social studies and business building, and the arts and shop building.
During restructuring in the 1990s the use of the buildings was altered so that some of the classroom buildings were designated for the use of one of five specialty schools within the larger school, including a small specialized school for those with learning handicaps.
In the past four years, Piner High School has remodeled more than half of the buildings, as well as adding new structures.
