License Plate 8PDJ791 in California, United States

Blocked Driveway & Illegal Parking at 2618 Sutter St Lower Pacific Heights. Dark blue Toyota Camry with license plate CA 8PDJ791 The people on our block at 2618 sutter do not have a parking permit, but continually take the space in front of their house and never get cited. they can easily park across their driveway, but always take the space instead. parking is difficult in our area and they rob the rest of us of a valuable parking space. can something be done?
