The landscape of eastern Hillsborough County underwent a visible transformation by the mid-1950s, as agricultural settlements like Sydney and Dover were increasingly defined by industrial extraction. Large swaths of land are marked as Strip Mines, with later updates showing the extensive Reclaimed Strip Mine areas that characterize the region's phosphate mining history. These industrial zones exist alongside established community landmarks, including Dover Ch and the Trapnell Sch.
