 A turning point for development in the Everglades came in 1969 when a replacement airport was proposed as Miami International Airport outgrew its capacities . Developers began acquiring land , paying $ 180 an acre in 1968 , and the Dade County Port Authority ( DCPA ) bought 39 square miles ( 100 km2 ) in the Big Cypress Swamp without consulting the C & SF , management of Everglades National Park or the Department of the Interior . Park management learned of the official purchase and agreement to build the jetport from The Miami Herald the day it was announced . The DCPA bulldozed the land it had bought , and laid a single runway it declared was for training pilots . The new jetport was planned to be larger than O 'Hare , Dulles , JFK , and LAX airports combined ; the location chosen was 6 miles ( 9 @.@ 7 km ) north of the Everglades National Park , within WCA 3 . The deputy director of the DCPA declared : " This is going to be one of the great population centers of America . We will do our best to meet our responsibilities and the responsibilities of all men to exercise dominion over the land , sea , and air above us as the higher order of man intends . "
