In response to this devastation, Rapid City received an outpouring of private donations and millions of dollars in federal aid. It was able to complete a major part of its 1949 plan: clearing the area along the Rapid Creek and making the floodplain a public park. In other areas, new homes and businesses were constructed to replace those that had been destroyed. Rushmore Plaza Civic Center and a new Central High School were built in part of the area that was cleared. The high school opened in 1978, with the graduating class that year attending classes in both the original school (housed in what is now Rapid City High School and community theater) and the new one.
