The increases take effect Dec. 7 and will be in effect for at least six months.

BART officials evaluate parking lot usage every six months and adjust parking fees up or down based on usage. Lots that are full might see a fee increase of 50 cents, up to a maximum of $3 per day at most stations, while lots that are less than 95 percent full might see a decrease.

Parking fees can be paid for with a Clipper Card, which must be linked to BART’s parking program, EZ Rider, in advance of use. Parking fees can also be paid with cash or with a Blue Ticket, which must also be used to enter the fare gates.
