• Oak Grove Merchants' Association flyer, circa 2000

Oak Grove Plaza opened for business in 1965, with Lucky Stores, Wells Fargo Bank and Standard Oil (now Chevron) as the first businesses serving the growing needs of families near the border of Walnut Creek and Concord.

Back then, Treat Boulevard wasn’t the bustling boulevard it is today. As a matter of fact, Treat Boulevard didn’t extend further than Bancroft Road. David Zuckerman, developer of Oak Grove Plaza and homes in the Diablo Valley, saw the need to extend Treat Boulevard further east. This allowed families more direct access to the new private high schools in the area, Carondelet and De La Salle. The new access also spurred more development in the area, including the building of homes, apartments, as well as the building of the Latter Day Saints’ facility on Treat near Oak Grove Plaza. New residents in the area led to the expansion of Oak Grove Plaza.


With the addition of Trader Joe’s and other new merchants, Oak Grove Plaza has become a favorite destination of shoppers and diners throughout Central Costa Costa County. With plenty of free accessible parking and personal service, Oak Grove Plaza merchants continue to do what we’ve always done best—taking care of the needs of our local friends and neighbors.
