Part 2: Preserving Historic Value, Providing Modern Seismic Safety

A California public school campus constructed in 1924, partially retro fitted in 1936, recognized as a historic place in 1977, vacated shortly after that in 1978, partially retrofitted again in 1989, shuttered in 2012, was brought back to life in 2018.
