The Pacific Coast Railway built an electrified line from Santa Maria to Betteravia in 1906.
In 1950, the Union Sugar Company decided it no longer wanted to remain in the renting business and gave notice to all residents to evacuate. The homes were sold for an average of $50 each. Most of the homes were bought by their renters and moved, and some were bought by other individuals.
On March 8 1988, the sugar plant, then owned by Imperial Holly (now known as Imperial Sugar), suffered a dust explosion and fire which resulted in the injury of eight employees, seven critically. Following the closure of Holly's Betteravia sugar plant in 1993, Betteravia became a ghost town with many vacant and demolished buildings.
