The second, Edgemont Elementary School, was built on a large lot bounded by Elm, Acacia, and Jenevein avenues.
[3] With the passage of the Field Act by the California legislature following the devastating 1933 Long Beach earthquake, steps were taken to seismically upgrade existing schools or close them.
In 1941, the New Edgemont Elementary School was built a block west of the district's offices, at 875 W. Angus Avenue.
The district's third school, El Crystal, was built on a small hill overlooking San Bruno City Park in 1948.
The district's first intermediate school, housing San Bruno's seventh and eighth grade students, was Parkside, which opened in 1954 on Niles Avenue.
With the development of the massive Rollingwood and Crestmoor subdivisions in western San Bruno in the 1950s, the district built additional elementary schools.
Decima M. Allen was San Bruno's librarian from 1937 to 1955, overseeing the construction of the present main library next to the city hall in 1954; she also served on the school board for 25 years and was president of the Edgemont PTA.
As a San Bruno Herald reporter observed, Sandburg looked around at the school's children, smiled, and audibly marvelled at their young faces.
[7] In 2018, it was decided that El Crystal and Rollingwood would close, due to financial difficulties being experienced by the district.
