Permanent construction of the sort Flagler was referring to would not come cheaply, however. Early in 1910, Flagler wrote to John Carrere, designer of the Ponce de Leon Hotel in St. Augustine, that repairing the damage caused by the hurricane had actually cost him $1 million, and reiterated that it had taught him a valuable lesson about upgrading the quality of the work. He estimated that it would require at least another $9 million to push the track to Key West, a figure that did not include the costs of a terminal and docking facilities.
