I acknowledge that “The Los Angeles Coroner's Inquest concluded the disaster was primarily caused by the unsuitable soil conditions on which the eastern abutment of the dam was built, but which would have been impossible for the geologists of the 1920s to detect.” (Guyer, 2011, p. 12), but we cannot neglect the fact that he did not take the actions of enlarging the base after the height increase of the dam. The fact that Mulholland was a self-taught and he was giving the power to handle such a big project on his own was problematic, because clearly he lacked necessary skills and training as a professional engineer to fulfil the assignment. However, the positive outcomes of this tragedy are that for all projects from that time to date are conducted
