By 1910, because of an ongoing struggle to secure an adequate water supply, the townsmen voted for Hollywood to be annexed into the City of Los Angeles, as the water system of the growing city had opened the Los Angeles Aqueduct and was piping water down from the Owens River in the Owens Valley. Another reason for the vote was that Hollywood could have access to drainage through Los Angeles sewer system.The name of Prospect Avenue was changed to Hollywood Boulevard and all the street numbers in the new district changed.
