The tract of land on which it sits was annexed by the city of Hobart from unincorporated Ross Township in 1993.

There are three vacant anchors stores that were once Dick's Sporting Goods, Carson Pirie Scott, and Sears.

The former Carson's had housed the cafeteria-style "The Garden Restaurant" by the entrance near the security garage on the south side of the mall from 1975 to 1989.

[6] Westfield Southlake underwent a significant expansion in 2006 that added Dick's Sporting Goods and a Borders bookstore, as well as several structures in the mall's outlot areas, including a 12-screen AMC theater, a Fifth Third Bank branch, Chipotle Mexican Grill, Potbelly Sandwich Works, Red Robin, and Buffalo Wild Wings.

In July 2011, Borders announced it would be closing all of its stores by the end of September due to Chapter 7 Bankruptcy liquidation, including the Southlake Mall location.

[12] On April 18, 2018, Carson's announced it would be closing as parent company The Bon-Ton Stores was going out of business.

[17] On November 25, 2022, Kids Empire, an indoor playground and party zone, announced that they would be filling a portion of the former Dick's Sporting Goods.
