the 1960s around the idea of beautifying the riverfront and turning Havermale Island into a park. With support around beautification growing, Spokane Unlimited would go on to commission a feasibility study in 1970 for using a marquee event, proposed to be in 1973 to celebrate the centennial of Spokane, to fund the beautification. However the report stated that a local event would not have the stature to bring in enough funding for the group's beautification aspirations, and that it needed to go bigger; it suggested that Spokane host an international exposition that could bring in state and federal dollars, as well as tourists from outside Spokane, to fund a riverfront transformation. The idea to host caught on—inquiries were made to the Bureau of International Expositions as well as an additional study that was commissioned in the fall of 1970, and results both came back very positive. The 1974 world expo was identified as the target event. Efforts to host the expo just three-and-a-half years later began immediately and was a tall order considering that Spokane would be the smallest city at the time to ever host a World's fair, and that the proposed site had 16 owners, including the railroads. Funding came from local, state, and federal sources, including a new business and occupation tax that the Spokane City Council passed in September 1971 after a ballot bond measure to provide local funding failed the month prior. The event was officially recognized by then-President Richard Nixon in October 1971, and the following month, the Bureau of International Expositions gave their sign-off on the event as well. Construction With approvals and funding falling in place, one last challenge was transforming the site and removing the railroads. Through intense negotiations, the Expo '74 planners, including King Cole were miraculously able to convince the railroads to agree to a land swap and donate the land needed for the Expo site. The railroads were consolidated onto the Northern Pacific Railway lines further to the south in Downtown Spokane, freeing up the site for construction. Construction that would transform the site to host the environmentally-themed Expo '74 would begin in 1972. Spokane was the smallest city to host a world's fair recognized by the Bureau International des Expositions until Knoxville, Tennessee held the 1982 World's Fair eight years later (although the Spokane metropolitan area is still smaller than the Knoxville metropolitan area). World's Fairs began
