History
Port Costa was founded in 1879 as a crossing point for railroad ferries. For a time, it was the United States' busiest wheat-shipping port and had a reputation as a colorful, sometimes violent community. After California's wheat output dropped in the early 20th century and other industries rose in Contra Costa County, Port Costa lost population and importance. Since the late 1960s, it has mainly been a small shopping venue for antique hunters.
