Problem:Passage: Edward J. DeBartolo Corporation formed a joint venture with Homart Development Company, a shopping mall development subsidiary of the department store chain Sears, to begin development on Castleton Square in 1971. DeBartolo announced the mall's development in January of that year and began groundbreaking soon afterward. The original plans called for a Y-shaped enclosed mall with three anchor stores: Sears, J. C. Penney, and Rike Kumler Co. (Rike's), a department store chain based out of Dayton, Ohio. The mall would be situated on 82nd Street just outside the Interstate 465 beltway within the Castleton neighborhood on the northeastern side of Indianapolis. It was the second of three malls built by DeBartolo as a part of its expansion into Indianapolis, following Lafayette Square Mall in 1968 and preceding Washington Square Mall in 1974. The company chose to build on the northeastern side of the Indianapolis metropolitan area, as the area was projected for further suburban growth in the intervening years. Similarly, research conducted by Sears showed a trend in residential growth to the city's northeast side, thus creating a market which the chain deemed suitable for a new store. To accommodate for mall traffic, the Indiana Department of Transportation expanded 82nd Street to a four-lane divided highway. Federated Department Stores (now Macy's, Inc.), then-owners of the Rike's chain, confirmed that the third anchor of Castleton Square would instead be Lazarus, a Columbus, Ohio-based chain then also under their ownership. Also confirmed as tenants for the mall by 1972 were a Kroger supermarket, an F. W. Woolworth Company dime store, and a three-screen movie theater. Inline tenants would include Robert Hall Clothes, Hickory Farms, Kinney Shoes, Zales Jewelers, Waldenbooks, and Orange Julius.
