Maritime Museum, Aquatic Park Historic District
San Francisco Maritime National Historic Park, CA

Maritime Museum opened to the public in January 1939. The building featured a slate mural designed and carved by sculptor Sergeant Johnson under the direction of the Works Progress Administration of the New Deal. The mural is located at the south-facing principal entrance of the building and has been in a condition of disrepair and deterioration for many years. The slate façade is a significant work of art in addition to being an important architectural feature of this prominent City landmark.

ARG assessed the condition of sculpture, developed conservation treatments, and provided cost estimates for preservation of the bas-relief sculpture. We also prepared construction documents for this preservation effort, which included an innovative method for removing soluble salts from the panels using ultra-sonic cleaning technology and surface treatments for the masking of incised graffiti.
