Narrative:

X on a training flight in a beech duchess. I was departing the san carlos airport using runway 30 and using a belmont slough departure. While at approximately 700 ft MSL another aircraft, cherokee Y, passed near and to my right traveling in the opposite direction. Y was observed to take evasive action, and that is when we spotted it. I believe the cause of this event was two fold. First, pilot error on the part of the pilot of Y upon entering the san carlos traffic pattern and lack of good judgement. Second, ATC failing to notice that this aircraft was entering the traffic area at the departure end of the active runway! Note: I recognized the aircraft in question and I could also read the n-number as it passed off my wing.
