Flood Walker of Santa Ana.","why_significant":"The nomination argues it is significant for its role in educating Orange's youth, first as Central Grammar School and then as the city's first junior high school from 1919 until the early 1960s. It is also valued as the largest, most imposing and most intact example of its architectural style in Orange, and the oldest remaining junior high school building in the county.","narrative":"Built in 1914 at 370 North Glassell Street in Orange, California, this two-story reinforced concrete school was designed by Santa Ana architect J. Flood Walker in the Lombardic Italian style. A red-clay-tile hipped roof, twin square towers, a central gable with arched corbel-tables, and decorative bands of glazed brick and tile in tan, rust and brown set it apart. The walls are coated in original Kellastone stucco, and a wide front lawn and pepper trees preserve its early setting. It opened as Central Grammar School, then became Orange's first junior high in 1919 when several local districts merged into the Orange Unified School District. For decades it hosted plays, assemblies, athletics and club meetings. Since the early 1960s it has housed district administration. It is considered the largest and best-preserved example of its style in the city, and the oldest remaining junior high school building in the county.","period_of_significance":"1914 - 1943","architect_builder":"Walker, J.
