  • On Oct. 21, 1914, Walnut Creek incorporates as Contra Costa County’s eighth city. The city comprised 500 acres. A primary initiative for incorporation was the desire of downtown businesses to pave Main Street, which was finally accomplished in 1921. Harry Spencer is elected first president (mayor) of the Board of Trustees. The Board was renamed the City Council in 1929.

    Population: 500

  • With a grant from the Carnegie Library Foundation, Walnut Creek’s first library opens at Main and East (now Giammona) Streets on land donated by Robert Noble Burgess.

    Population: 520 (est.)

  • The City finally completes the paving of Main Street. Subsequently, Main Street is designated a State Highway, doubling as sections of Highways 21 and 24. By the 1950s, Main Street traffic is often at a standstill on weekday afternoons and Saturdays.
