Parked cars are blocking my driveway, or mailbox or intersection. Can I get a “No Parking” sign or yellow curb paint?

Due to multiple factors, the city no longer paints curbs. If signage has been defaced or removed at or near a mail box unit, one may possibly be supplied by the postal service. If a driveway is being blocked, reporting to the city's code enforcement department (503-668-5566) is the best option.
