Gardiner W. Spring Auditorium

Chaffey High School, Ontario, CA

Opened in 1939 and named for a former superintendent of the Chaffey Union High School District, Spring Auditorium was a standout space known for both its acoustics and its design.

In 2017, EverGreene was engaged to conduct finishes investigations and conservation testing. The team discovered that the acoustic plaster ceiling contained asbestos, requiring abatement and full replacement of both the ceiling and mural. With that, the project shifted from conservation to careful replication.

EverGreene thoroughly documented the ceiling using digital photography and created pounce patterns in its Brooklyn-based design studio. Using a rectified grid system, the team accurately recreated the mural on a new acoustic plaster surface. Original decorative painting was also reinstated throughout the auditorium and surrounding public spaces.

The auditorium was rededicated in July 2019 and remains a valued gathering place for the district and its community.
