The urban renewal of downtown during the 1970s has lost much of its impact due to suburban development, including the Southern Hills Mall. Department store J. C. Penney, moved from their downtown location in Sioux City, which opened in 1975 moved into Target's former location in 2004. The Sioux City Public Museum is renovating the building, moving from the undersized historic Pierce Mansion. In 2007, another department store, Younkers closed their location in downtown Sioux City, only choosing to operate in Southern Hills Mall. Hom Furniture has moved into this space from a much smaller store in Sioux City.
