On March 6, 1972,
General Growth Properties announced plans to build a new mall at the intersection of Southeast 14th Street and Army Post Road. The mall was known as Army Post Plaza during the planning and construction stages, but it was renamed Southridge Mall shortly before construction was completed. Southridge Mall opened on October 15, 1975, two months after
Valley West Mall opened in
West Des Moines.
Younkers was the first anchor to open, with
Sears following in 1977. An expansion in 1978 added
Montgomery Ward as a third anchor, while a
Richman Gordman department store became the mall's fourth anchor in 1982. Plans to add
Dillard's to Southridge in 1987 were immediately opposed by Younkers, who claimed that the store's lease limited Southridge to four department stores. Younkers sued Southridge's management over this issue, but a federal
magistrate ruled against Younkers in June 1990 even though Dillard's backed out of its plan to build at Southridge before the ruling. After the failure to attract Dillard's,
Target became the mall's fifth anchor in 1992 while the rest of the mall was renovated; the expansion increased Southridge's floor space to just over 1 million square feet (93,000 m2). Richman Gordman closed in 1992 after the chain declared
bankruptcy, and
JCPenney moved from downtown Des Moines to Southridge two years later to replace that anchor spot. On January 24, 2011, it was announced that JCPenney would close its store in June 2011, though one JCPenney store in Des Moines at
Valley West Mall would remain open. General Growth Properties, which was originally based in Des Moines, sold Southridge to the Equitable Life Assurance Society in 1984 as part of its
real estate investment trust liquidation that year. General Growth continued to manage Southridge until a partnership of the
Simon Property Group and
Macerich acquired the mall in March 1998 as part of a 12-mall deal. Macerich manages the mall as part of the deal. The occupancy rate at Southridge declined in the 2000s, as competition from
Jordan Creek Town Center and other shopping areas such as
Merle Hay Mall affected the mall's business. Renovation work in late 2006 and 2007 resulted in a new children's play area in the food court,
Wi-Fi access, new seating areas, and remodeled restrooms.
Steve & Barry's opened a new store near JCPenney on October 24, 2007, but that store closed at the end of 2008 as the chain liquidated its remaining stores. By December 2009, 40 out of 91 inline store spaces were reported as vacant. Some of the empty storefronts at Southridge had been filled with tenants that are not usually associated with malls, such as churches, offices and an animal shelter. In 2009,
U.S. News & World Report named Southridge as one of 84 "endangered malls" due to its low sales per square foot and vacancy rate. On May 3, 2016, Sears announced that they would be closing in August 2016. On April 18, 2018, Younkers announced that they would close its location, as the parent, Bon-Ton Stores, was going out of business. The store closed on August 29, 2018. This left Target as the only remaining anchor. ==Renovations==
