At their meeting on Thursday, directors voted 8-1 to select San Francisco-based TransMart. The lone "no" vote was cast by Director Tom Radulovich of San Francisco.
BART officials hope that having more businesses at their stations will bring them more revenue to pay for core services and also provide more conveniences for passengers.
Among the types of businesses that could be located at BART stations are vendors of take-away food and convenience items, local farmers markets, books and magazines, financial services, technology and communications centers, health and wellness centers, and beauty centers.
However, the new businesses won't start operating anytime soon, as TransMart will first do two studies.
The first study will analyze station capacity and passenger flow and the second will look at utilities, patron access, signage and transit equipment.
If the project goes forward, TransMart will oversee all vendors and select subcontractors that would operate businesses at the various BART stations.
