The airport site, though relatively flat, was lowered in some areas and raised in others, requiring the moving of 110 million cubic yards of earth. 110 million cubic yards is approximately one-third the amount of dirt moved during the Panama Canal project. This amount of earth, if dumped into a single pile, would cover 32 city blocks to a depth of one-quarter mile.
