While I've never tried either of the spots listed below, they should work.
The intersection of Nurse Slough Road and Highway 12 should offer good views of aircraft banking in for RWY3R when working the pattern. This spot, however, is tricky because it does get backlit quite early in the day when pattern work isn't being done. The sample shots are heavily cropped, but show what theoretically should be possible.
The sports complex front lawn should offer a good view for RWY21R departures in the afternoon. You're a little further from runway centerline than the corner spot, but also a little further from runway threshold so the shots should look similar. This spot should also offer good views of aircraft parked on the remote stands.
