The South Dakota Ellsworth Development Authority has been steadily working over the years since the Base Realignment and Closure (BRAC) hearings in 2005 to keep Ellsworth Air Force Base off of any future closure lists. The Rapid City Journal reports that the group has been doing this by helping to keep base facilities updated and trying to buy plots of land near the accident potential zone to keep civilian homes out of potential danger. These steps were identified as potential problems that the base faced during the last round of BRAC hearings in 2005.
