By 1976, a 9,000 square foot addition (in dark gray) has been built on the mall's northeast corner. This was the only expansion ever done to the mall. Moreover, various stores have been rebannered. Even more have closed up and moved on. The complex is in a downward spiral, with half of its leasable space sitting vacant.

In the late 1980s, WHITTIER DOWNS was on its last legs. A redevelopment was announced in November 1987, which got underway in early 1988. The mall was bulldozed. A portion of KING COLE SQUARE (in black) was left standing and was incorporated into the new SANTA FE SPRINGS MARKETPLACE. Sections in dark gray were built in 1988 and 1989, while those shown in lighter gray were completed in 1991.
