The St Francis Dam disaster of 1928 is considered the worst American civil engineering disaster of the 20th century William Mulholland, of which Mulholland Drive is named after, hastily oversaw the project. He ignored geologists warnings to not build the dam due to unstable foundations and went a step further by opting to use cheaper materials to get the job done quicker. Why? Because LA needed more water and fast. But this dam construction came right after building the first ever long distance
