I think some of the waypoints around KSJC are missing I don’t know what is with the Bay Area missing so many waypoints, especially near KSFO so all you have to do is just visualize it.
When I take off from KSJC heading north (like KPDX, KSEA, or KMSP), I turn right after about 10 to 15 seconds after leaving the ground at KSJC. I would turn right until I am right downwind of Runway 30R. Continue downwind until you are able to turn right again without flying over KSJC if you were to fly straight ahead.
Follow the path below:
Takeoff from Runway 30R, loop to right downwind runway 30r, pass the red line (as you can see, the red line is after the thresholds of Runways 30R and 30L. After passing the red line, you can now head for your destination.
Continue south if you are heading south (KBUR, KLAS, KSAN, KLAX, KONT @Daniel14, etc)
If you are heading west (Hawaii, Tokyo, Beijing), pass the red line and turn right to proceed onto your flight plan.
The path above demonstrates the path if I were to head north as if I was departing for KSEA.
Heading east to me is a little weird. For example, if you want to fly to KDFW or KDAL, you can either take the SID leading north or the SID leading south. It really depends on your flight plan. If you are heading directly east like KCLT or KDEN, you would follow the path in the second picture below.
My point is: There are some missing waypoints near KSJC and your flight plan really determines what SID you should take. **Main thing when taking off from 30R is to always turn right, go downwind, pass the red line which means passing the thresholds of Runways 30R and 30L, and then continue on your flight plan.
