Georgetown existed as an independent city from 1904 to 1910, when it was annexed by Seattle. Georgetown incorporated in 1904 largely as a defense against the prospect that Seattle would adopt local Prohibition, which could impact Georgetown's ability to keep operating saloons and breweries as an unincorporated area adjoining a dry city. With Seattle increasingly cracking down on public sinfulness within its boundaries, Georgetown caught the windfall with its twenty-four 24 hour saloons, some of which advertised lodging arrangements, and horse racing track. Once Seattle rejected local-option Prohibition, a movement for annexation gained widespread support. Following presentation of a petition for an annexation vote in 1909, a special election was held on March 29, 1910. The annexation proposition passed with 389 votes in favor and 238 opposed. The City of Georgetown, with its 4000 residents, was officially consolidated with Seattle on April 4, 1910. The Old Georgetown City Hall (1909) is now on the National Register of Historic Places as is the Georgetown Steam Plant (1906).
