Dec. 26-31, 1956: California has been a frequent beneficiary of Seabee firefighting forces. Forest and brush fires have been a special hazard during the state’s dry season. Seabees from the Naval Construction Battalion Center (NCBC), Port Hueneme, California, manned the fire lines in the Malibu Canyon – Zuma Point area and helped contain one of the worst brush fires in California history. Seabees fought the blaze alongside civilian firefighters. In addition, Seabees were busy putting out small fires that cropped up along the highway, digging trenches, cutting fire breaks in the valley and gullies surrounding the Zuma Mountain Range, helping residents protect their homes from the ravenous flames.
