Hilltop Horizon, formerly known as Hilltop Mall, East Bay Science and Technology Center and The Shops At Hilltop, was a regional shopping center in the Hilltop neighborhood of Richmond, California. Hilltop is managed and co-owned by Prologis, Inc. The anchor store is Walmart. There are 3 vacant anchor stores that were once Macy's, JCPenney and Sears. History Hilltop Mall opened in September 1976, built on land previously occupied by an oil storage tank farm owned by the Chevron Corporation. The mall was developed by A. Alfred Taubman, who also developed several other shopping malls in the East and South Bay Area, including Eastridge Center in San Jose, Stoneridge Shopping Center in Pleasanton, and Sunvalley Mall in Concord. Originally, it was anchored by red-tiled Capwell's, JCPenney and Macy's. Both Macy's and JCPenney originally had stores in downtown Richmond, but while Macy's had closed its downtown store a couple of years earlier, JCPenney kept its downtown store open for a year after Hilltop opened. Capwell's changed its name to Emporium-Capwell in 1979, before becoming simply The Emporium in 1990. Sears was added in 1990 in a newly built north wing addition, which was an expansion of this property. Once opened, the mall attracted the major anchor stores from Richmond's downtown, with several major national chain stores closing downtown locations (although many acknowledge that the trend predated Hilltop due to economic and safety issues). 1996: Emporium closes The mall remained largely unchanged until 1996, when the Emporium store closed following its merger with Federated, who owned Macy's. The store remained vacant until October 1998, when Macy's refurbished and relocated their existing store into the former Emporium space and closed the original Macy's store. The space would remain vacant until Walmart took over the space in Spring 2007. 1998: Sale to GM Pension Trust The GM Pension Trust assumed full ownership of Hilltop Mall in 1998, retaining Taubman Centers as manager. In 2004, the GM Pension Trust sold a half-interest in a portfolio of shopping centers, including Hilltop, to The Mills Corporation, which also assumed management of the center. After several years of delay, Walmart opened on April 11, 2007 on the site Macy's vacated in 1998. 2007: Sale to Simon Property Group In July 2007, Simon Property Group purchased the entire Mills Corporation portfolio, including other Bay Area properties: Stoneridge Shopping Center in Pleasanton, California and Great Mall in Milpitas, California.
