The 1890 establishment of the Seattle, Renton, and Southern Railway and aggressive promotion of real estate brought settlers to the mill town of Columbia. The town’s thriving lumber industry helped supply Seattle with timber for reconstruction after the Great Fire of 1889, and many goods were also shipped to Columbia from Seattle via the railroad. Columbia was incorporated in 1892 with a five-member Town Council which quickly established a Board of Health to employ a "reputable physician" charged with examining cases of contagious disease. A volunteer fire department was created in 1902 including a hose company and, soon thereafter, a chemical company. In 1903, Columbia reached a contractual agreement with the City of Seattle for the purchase of water. Also in that year, the Snoqualmie Falls Power Company received a franchise to install and operate an electrical power plant for the town. Columbia achieved city of the third class status in 1905 when its population reached 1500, the required total established by State law. The Mayor called a special election in September of 1905 and the public voted in favor of the "advancement of the Town of Columbia to a city of the third class." Annexation to the City of Seattle came in 1907 following a petition by citizens to the City Council to hold a special election on the matter. Although opposition to annexation had initially been strong, due to citizens’ desire for local control, the March 5 vote was overwhelming, 109-3 in favor of annexation to Seattle. Consolidation occurred on May 3, 1907. The Columbia City neighborhood, with much of its historical core intact, was designated a Seattle Landmark District in 1978.
