Narrative:

As we held short of runway 25 in sba a small cessna was cleared for takeoff. We were next in line and cleared for takeoff and assigned runway heading; maintain 3;000 ft. We were never instructed to keep the cessna in sight so I assumed that the controller would have turned the cessna so it would not be in our flight path. As we climbed through 1;000 ft we received a 'traffic; traffic' TA followed by an RA to descend. When I looked at the TCAS display; I noticed that the traffic was only 100 ft above us.the pilot flying complied with the RA. I began looking for the traffic and saw the cessna. At this point it was approximately 200 ft above us. We told tower that we initiated a TCAS descend and that we were now resuming our climb. The only response from the controller was; 'contact departure.'

Title: Alerted to and provided avoidance guidance by TCAS TA and RA warnings; a BE-400 flight crew experienced a NMAC with a small Cessna which departed SBA ahead of them. ATC had failed to provide appropriate warnings or separation clearances prior to clearing them for takeoff.
