Urbandale was incorporated as a city on April 16, 1917. In its early days, Urbandale served as a streetcar suburb of Des Moines with four coal mines. Urbandale served as the end of the Urbandale Line after plans to build a railroad from Des Moines to Woodward were abandoned because of right-of-way issues. The coal mines had closed by the end of the 1940s while streetcar service ended in 1951. In 1920, shortly after the city incorporated, Urbandale had 298 people.
