A site plan of the mall from the same time. Hinshaw's had been enlarged in the early 1960s. By the early '70s, the store had expanded into an adjacent supermarket space and an adjoining parking garage had been completed. In 1974, the shopping concourse was enclosed and climate-controlled. On the southwest corner of the site, three outparcel stores were built; Von's (in the late '50s) and Thrifty Drug and The Akron (in 1978).

What remained of the mall post-temblor was knocked down. Hinshaw's, which had incurred minor damage, was left standing and was incorporated into THE QUAD AT WHITTIER, a new open-air power center. Structures in dark gray were complete by 1991. Those in medium gray were dedicated in 1992, with components indicated in light gray being finished in 1995.
