Grover Beach was originally known as Town of Grover, which was founded in August 1, 1887 by Dwight William Grover. This occurred when he filed his plans at the San Luis Obispo County Court House and eventually founded what was to be known as City of Grover City. There was a popular vote that allowed incorporating on December 21, 1959 as City of Grover City. However, the name seemed redundant so some people were seeking better names, especially ocean-oriented names. In 1992, there was another popular vote, where the town's name was officially changed from "City of Grover City" to "Grover Beach" to emphasize the seaside location.
