Downtown Richmond is the old center of Richmond, California. The area is roughly bordered by 6th street to the west, 23rd Street to the east, Barrett Avenue to the north, and Macdonald Avenue to the south.[citation needed] The area once featured major department stores and other chains such as J.C. Penney, Macy's, S. H. Kress & Co., and Sears before Hilltop Mall was built in the 1970s.[citation needed]The area is currently undergoing a revitalization effort by the city, which has included the Richmond Shopping Center anchored by a supermarket. The Richmond Transit Village—coined Metro Walk by the developers, the Olson Company—has also been built, along with remodeling of the Richmond BART and Amtrak station and a bus transit center served by AC Transit and Golden Gate Transit. A Kaiser Permanente hospital and a Social Security Administration processing center provide for a majority of the jobs in the area.
