Narrative:

As we were cleared for takeoff we were also given a revised level off altitude of 3000 ft. After being handed off to socal departure; we were made aware of VFR traffic at 3500 ft. We did see him and I tried to shallow out my climb; however we still received a TCAS RA commanding us to descend. The RA was not preventable with our takeoff clearance and us simply flying the channel 2 departure. The VFR traffic was close enough to trigger the RA. Flying the noise abatement departure takes some attention and it is not ideal having to descend out of 2700 ft to avoid traffic flying it. I don't feel that we made a mistake in this case; but want to raise attention to this issue.
