Nordstrom: 169,000 square feet (15,700 m2); original tenant of MainPlace 1987, closed 2017[2] MainPlace Mall was built on the site of the much smaller open-air center that Los Angeles-based department store Bullock's opened in 1958, first called Bullock's Fashion Square.

There was parking for 3000 cars and opening day drew crowds of 40,000 people from across Orange County, according to the Los Angeles Times.

[6] After a period of decline, JMB Property demolished most of the shopping center, except for the anchors, and had it replaced by MainPlace in 1987.

[13][2] By 2019, MainPlace Mall had seen 35 store closures and a $54 million drop in gross sales over a two-year period.

In March 2019, it was announced that a US$300,000,000 project would transform the mall into an outdoor center by removing its central portion, adding a food hall in "European marketplace" style, an interactive play center for children, upgrades to its movie theater, a grocery store, and two apartment communities with 700 new residential units.
