In the 1940s, a hilltop was shaved away to produce landfill for the expanding San Francisco Airport, which received an "international" designation in 1954 with the completion of the Central Terminal. Spurred largely by the desire to secure the Mills estate for residential use and by the efforts of Millbrae's weekly newspaper, the Millbrae Sun, residents heatedly discussed incorporation for over a decade before voting to incorporate. Finally, on January 14, 1948, residents of Millbrae traveled to Sacramento to present their new city's charter. W.F. Leutenegger was elected mayor to represent Millbrae's nearly 8,000 residents. That year, Green Hills Elementary School opened as Millbrae's first new school in over 25 years, in anticipation of the educational needs of the post-war "baby boom" children. The new city's chief industries were agriculture, floriculture, dairy, and porcelain manufacturing.
