This airplane photo of the Santa Monica Bay area, on which the site where Bell plans to estalish a cement plant and allied industries is outlined by Bell's own engineers, is an exhibit in the cement plant case before the city planning commission. Even minor blasting, such as would be done daily at the quarry, would be damaging to homes and annoying to residents, according to Rieber. Major blasts, in which as high as 70 tons of black powder would be used, would rock the countryside for miles around, Rieber tesified before the commission. Photo dated: October 11, 1929.
