CHICAGO (CBS) — Less than a year after Wal-Mart won approval of plans to build a 150,000-square-foot supercenter in the Chatham neighborhood, the company also was planning to build a 10,000-square-foot convenience store less than two blocks away.

Wal-Mart spokesman Steven Restivo confirmed Wednesday afternoon that the company will open a Wal-Mart Express store in an existing 10,000-square-foot building just east of a Potbelly sandwich shop at the corner of 83rd Street and Holland Drive.

It would be Wal-Mart’s smallest format store yet, about the size of most 7-Eleven stores and would carry similar grocery items as most typical convenience stores.

The store would be located less than two blocks from a planned Supercenter in Chatham.

Last July, the City Council signed off on plans to build a Wal-Mart Supercenter at 83rd Street and Stewart Avenue in the Chatham neighborhood. When completed next year, it would be the city’s third Wal-Mart, along with its existing store in the Austin neighborhood, and a store slated to open in the Pullman neighborhood next year.

The Wal-Mart Express planned for Chatham would be the second small Wal-Mart store in Chicago.

Last month, the company confirmed plans to open a a Neighborhood Market store at the Presidential Towers apartment complex in the West Loop neighborhood.

That store would be more than twice the size of the Chatham store. The West Loop location would be a a 26,000 square-foot store on the ground floor of Presidential Towers, 555 W. Madison St.

The West Loop store will sell meat, fresh produce and other groceries, and will include a pharmacy, deli and bakery. The store will also sell pet supplies, household supplies and paper goods.
