Chief Engineer, City and County of San Francisco, 09/1912-1932. During the Progressive Era, San Francisco, like many other US cities, purchased local utilities to break private monopolies that were seen as contrary to the public good; the City Government of San Francisco bought the Spring Valley Water Company to insure that water would flow without interruption to the city. During the city's critical rebuilding period after the Great Earthquake of 1906, O'Shaughnessy served as the influential City Engineer; it was under him, that many tunnels and reservoirs were built in the city and exploratory plans began for the Golden Gate Bridge in 1919; he also presided over the building of the mammoth and complex Hetch Hetchy Water and Power project, which involved constructing dams, reservoirs, pumping stations, power plants, a railroad and an aqueduct to provide water to post-Earthquake San Francisco; controversial as it was from an environmental standpoint, the completion of Hetch Hetchy enabled rapid growth in the Bay Area;
Michael O'Shaughnessy died, ironically, of heart failure just 16 days before water originating from the new Hetch Hetchy Reservoir in Yosemite began flowing through taps in San Francisco on 10/12/1934.
