Rockridge Park is a small "parkette" bounded by Rockridge Blvd, South,  Rockridge Blvd. North, and Rockridge Place in, would you believe -- Upper Rockridge.   The City of Oakland's website gives the park an address of 6090 Rockridge Blvd., Oakland, CA, but that address does not really exist.  The park has no real facilities, but is a pleasant green space with a few nice trees and some colorful plants at the point where Rockridge Blvd. splits into north and south sections, External Link:
