The sign for "Berkeley" uses a "B" hand (a flat hand) that moves downward a couple times. The fingertips are pointed upward, the palm is forward.
BERKELEY, California:
Model: Byron Cantrell (Native Deaf, Deaf School/Georgia, Deaf wife, Deaf kids, long-time ASL instructor.)
Notes:
Here is a video of Byron doing the sign "Berkeley." He is repeating the sign numerous times in an effort to show you how it moves. In everyday life you just need to use two downward movements. (Down, up, down).
