Portland's Civil Defense program of the 1940s and 1950s was once a national model. In 1956, Portland became the first city in the nation with an underground emergency response headquarters, built inside Kelly Butte. The CBS networked featured the city's civil defense program in their 1957 film A Day Called X. By the early 1960s, however, state and city leaders deemed this civil defense project a waste of funds and canceled the program.
